Introduction 4 Understanding automation Before you begin to work with macros, you need to understand the concept of automation. This section provides basic information about automation and about the macro-programming formats that are supported by the software. This section answers the following questions: • What is automation? (see page 5) • Which automation environments are supported? (see page 6) • What are the main elements of automation? (see page 11) • How is automation coding structured? (see page 14) What is automation? Many actions that you perform in the software can be combined with other, related actions into a single automated solution. Automating repetitive tasks saves time, reduces effort, and lets you perform operations that are too complex to perform manually. Automation can be used by programmers and nonprogrammers alike. This documentation does not teach programming skills to nonprogrammers; rather, it helps experienced programmers develop useful solutions within the software. If you are not a programmer, you may want to refer to other programming-related resources before continuing to read this documentation. What is a macro? Most macros are created to automate a series of tasks within an application. The simplest meaning of the term “macro” is the recording of a group of related actions that can be played back automatically, in sequence, whenever you need to perform them. Macros consist of instructions that are written in a programming language, and some programming languages provide access to additional, more advanced, actions that cannot be recorded. For the purposes of this documentation, a macro refers to a coded solution that performs tasks in the application by automating functions and subroutines (see “How are functions and subroutines built?” on page 16). Although you can record a sequence of actions in the software, the real power of automation is that you can add conditions and looping mechanisms to a recording. As an example, let’s consider a simple macro that applies a red fill and a 1-point outline to a selected shape. By adding a condition and a looping mechanism to the code, you can produce a macro that seeks out each selected shape and applies only the fill to text shapes and only the outline to all other shape types. Corel DESIGNER Technical Suite X5 Macro Programming Guide 5 After you create a macro, you can ensure that it has the desired outcome by setpping through its code one line a a time, or “debugging” it. When you are happy with the macro, you can keep it for future use and even share it with others. Which sample macros are available? The software includes sample VBA macros, which supply additional functionality, demonstrate automation in the suite, and provide sample code. The following sample VBA macros are included for Corel DESIGNER: • File converter (FileConverter.gms) — converts a vector or bitmap to a specified vector or bitmap format. You can choose export parameters by using dialog boxes associated with particular filters. You can also save each page as a separate file and set various page properties, such as size, orientation, and background color. The following file formats are supported: AI, BMP, CDR, CGM, CMX, CPT, DES, DSF, DXF, EPS, GIF, JPEG, PCT, PNG, PPF, SVG, SWF, TIF, WMF, and WPG. The following sample VBA macros are included for CorelDRAW: • File converter (FileConverter.gms) — converts a vector or bitmap to a specified vector or bitmap format. You can choose export parameters by using dialog boxes associated with particular filters. You can also save each page as a separate file and set various page properties, such as size, orientation, and background color. The following file formats are supported: AI, BMP, CDR, CGM, CMX, CPT, DSF, DXF, EPS, GIF, JPEG, PCT, PNG, PPF, SVG, SWF, TIF, WMF, and WPG. • Calendar wizard (CalendarWizard.gms) — generates customized calendars. You can choose the date range, layout, font, color, language, and many other options. You can also add holidays and moon phases. The following sample VBA macro is included for Corel PHOTO-PAINT: • HTML slide show creator (Slideshow.gms) — generates an HTML slide show from the images you specify. Open files can be added, ordered, and published as a series of HTML files, each of which displays one image and provides navigation buttons. You can create a title, alternate text, and a name for each slide. You can also choose a location and a name for the delineation folder; select the image folder; and specify notes, a caption, a URL, and more. Which automation environments are supported? For CorelDRAW versions 6 through 9, the only method of automating tasks was using the Corel SCRIPT™ language. Solution developers used Corel SCRIPT to create intelligent mini-applications for drawing shapes, repositioning and resizing shapes, opening and closing documents, and setting styles within CorelDRAW. Although the Corel SCRIPT language was useful for automating basic tasks, a more flexible and powerful solution became necessary. For version 10, CorelDRAW was enhanced with support for the Microsoft Visual Basic for Applications (VBA) engine, which handled behind-the-scenes automation. The addition of VBA made CorelDRAW immediately accessible to millions of VBA and Microsoft Visual Basic (VB) developers around the world. Since then, VBA has been supported by every version of the CorelDRAW software suite. More recently, the software suite added support for Microsoft® Visual Studio® Tools for Applications (VSTA), the successor to VBA. Currently, the software suite supports VBA version 6.4 and VSTA version 2.0. Understanding automation 6 Although CorelDRAW no longer includes the Corel SCRIPT editor, it does include the Corel SCRIPT run-time engine. Therefore, you can easily migrate scripts that were written for earlier versions of CorelDRAW to later versions of the software. For information on using Corel SCRIPT with CorelDRAW, see “Working with scripts” in the main Help file for CorelDRAW (draw.chm). In Corel PHOTO-PAINT, you can automate tasks by using VBA or VSTA to create a macro, or by using Corel SCRIPT to create a script. A macro is the better choice if you want to write the code that is required to carry out the task (by using VBA or VSTA), while a script is the better choice if you want to record the steps that are required to carry out the task (by using Corel SCRIPT). For information on using Corel SCRIPT with Corel PHOTO-PAINT, see “Working with scripts” in the main Help file for Corel PHOTO-PAINT (corelpp.chm). By supporting VBA and VSTA, the software suite offers a platform for the following: • developing powerful corporate graphical solutions — such as automated ticket generators, customized calendars, and batch file-processors • streamlining workflows — such as with on-the-fly page-layout mechanisms • customizing default software features — such as the creation, alignment, or transformation of objects • ...and much more! VBA and VSTA each provide their own fully integrated development environment (IDE), with contextual popup lists, syntax highlighting, line-by-line debugging, and visual designer windows. These features are particularly helpful to inexperienced developers. For more information on VBA and VSTA, see the following topics: • “What is VBA?” on page 7 • “What is VSTA?” on page 10 What is VBA? Microsoft Visual Basic for Applications (VBA) is a built-in programming environment that can be used to automate repetitive functions and create intelligent solutions in the software that supports it. VBA is a subset of the Microsoft Visual Basic (VB) object-driven programming environment. Usually, VBA is integrated into another application to customize functionality within that application. VBA is both a language and an editor. The VBA language cannot be used without its editor, and the VBA editor is the only utility in which VBA code can be edited or VBA programs can be run. The VBA language is an event-driven programming language. In other words, it is used to write code that produces a response to an action, such as clicking a button or choosing an option from a list box. When the action occurs, the appropriate event is called, and the code for that event is executed. Events can be simple or complex. For instance, you can code a single line that displays a message box or write an entire procedure that interacts with a database. With traditional procedural programming (or “object-driven programming”), the program starts at the first line and executes one line at a time. VB provides an example of an object-driven programming environment. Most of the code examples provided in this documentation are written in VBA. Understanding automation 7 The VBA editor — called the “Macro Editor” (formerly the “Visual Basic Editor”) in Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT — is an integrated development environment (IDE) that lets you manipulate the objects that are exposed by the object model of the application. To help you code macros, the Macro Editor provides context-sensitive Help for all the object-model elements that are available to you. VBA is an in-process automation controller. In other words, VBA can be used to control software features that can be automated, and VBA runs efficiently by bypassing the interprocess synchronization mechanisms. However, the automation that the in-process VBA can access can also be accessed by the following: • external out-of-process automation controllers (OLE clients) • applications that are developed in programming languages (such as VB, Visual C++, Windows® Script Host, and C++) that can be used to develop OLE clients • the VBA engines of other applications VBA provides a set of tools for customizing the graphical user interface of the software. These tools let you process and present data efficiently and effectively. Advantages of using VBA include the following: • familiarity of the VB language • rapid application development (RAD) IDE • fast run-time performance of the resulting integrated solutions • extensible forms package that supports ActiveX® controls for creating user interfaces • access to the full Windows application programming interface (API) and the underlying file system • connectivity to corporate data • integration with other software that is based on component object models (COMs) VBA lets you customize an application to suit your needs, or even integrate it with another VBA-enabled application by referencing the object-model components of the second application. Although VBA was developed by Microsoft and is built into almost all its desktop applications (including Microsoft Office), Microsoft licenses the technology to other companies (including Corel Corporation; Autodesk, Inc., in AutoCAD®; and IntelliCAD Technology Consortium, in IntelliCAD®). Software products that support VBA can typically be used to control each other, and they can even be used to control some software products that do not support VBA. Consequently, you can use VBA to build solutions in Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT that access a wide variety of other software products: databases, word processors, XML editors, and more. For a complete list of applications that support VBA, see the Microsoft website. Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT includes VBA version 6.4. How does VBA differ from VB and VBScript? The VB programming system is an advanced set of programming tools that provides advanced functionality and components for the Windows operating system and other Windows-based programs. For example, unlike VBA or VBScript, VB lets you create application extensions (DLL files) and stand-alone executable programs (EXE files). (The programs that you create with VBA must run inside the host application.) VB is a “visual”version of the BASIC programming language — that is, it provides visual cues within the editor. As a result, VB is an easy language to learn. In addition, Microsoft has greatly enhanced the original BASIC language, so that VB is both powerful and fast (although not as powerful as Java or C++, nor as fast as C). Understanding automation 8 VBA is a subset of the VB programming language, and it uses the programming structure of VB to manipulate the object-model elements that are exposed by an application. The manipulation of these objects results in small packets of code procedures within the application. These code procedures and resulting projects are called “addins.” VBScript (sometimes referred to as Microsoft Visual Basic, Scripting Edition) is also a subset of the VB programming language. VBScript is a Web-based HTML document scripting language. How does VBA differ from Java and JavaScript? VBA is similar to Java and JavaScript® in that it is a high-level, procedural programming language with full garbage collection and very little memory-pointer support. (For more information, see “How are memory pointers used, and how is memory allocated?” on page 17.) In addition, code that is developed in VBA, much like code developed in Java and JavaScript, supports on-demand compilation and can be executed without being compiled. VBA is also similar to JavaScript in that it cannot be executed as a stand-alone application. JavaScript is embedded within Web pages as a mechanism for manipulating the document object model (DOM) of the Web browser. Likewise, VBA programs are executed inside a host environment (such as Corel DESIGNER, CorelDRAW, or Corel PHOTO-PAINT) to manipulate the object model of the host. Most VBA applications can be compiled to p-code to make them run more quickly, although the difference is hardly noticeable because of the sophistication of today’s computer hardware. Similar compilation is possible with Java, but not with JavaScript. Finally, whereas VBA uses a single equals sign ( = ) for both comparison and assignment, Java and JavaScript use a single equals sign ( = ) for assignment and two equals signs ( == ) for Boolean comparison. (For more information, see “How are Boolean comparisons and assignments used?” on page 18.) How does VBA differ from C and C++? Like C and C++, VB uses functions. In VB, functions can be used to return a value, but subroutines cannot be used in that way. However, functions are used in C and C++, regardless of whether you want to return a value. (For more information, see “How are functions and subroutines built?” on page 16.) VBA allocates and frees memory transparently. In C and C++, however, the developer is responsible for most memory management. As a result, using strings in VBA is even simpler than using the CString class in C++. Finally, whereas VBA uses a single equals sign ( = ) for both comparison and assignment, C and C++ use a single equals sign ( = ) for assignment and two equals signs ( == ) for Boolean comparison. (For more information,see “How are Boolean comparisons and assignments used?” on page 18.) How does VBA differ from WSH? Windows Script Host (WSH) is an out-of-process automation controller that lets you do occasional scripting and automation of Windows tasks and can be used to control software. Although WSH is a useful addition to the Windows operating system, WSH scripts tend to be slow because they must run out of process, and they cannot be compiled (and must be interpreted as they are executed). WSH is a host for a number of scripting languages, each of which has its own syntax. However, the standard language that WSH uses is a macro language that resembles VB, so for standard scripts, the syntax is the same as in VBA. Understanding automation 9 What is VSTA? The successor to VBA, Microsoft Visual Studio Tools for Applications (VSTA) is based on Microsoft Visual Studio 2008. In Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT, the VSTA feature supports the .NET framework and enables development in two programming languages: Visual Basic .NET and Visual C#. Most of the code examples provided in this documentation are written in VBA. The VSTA Editor in Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT is an integrated development environment (IDE) that lets you create VSTA solutions for the software. Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT includes VSTA version 2.0. How does VSTA compare with VBA? Both VSTA and VBA allow you to create powerful macro solutions. With VSTA, you use the VSTA Editor as an IDE, and you use Visual Basic .NET or Visual C# as a programming language. With VBA, you use the Macro Editor as an IDE, and you use VBA as a programming language. If you want to perform any of the following tasks, you can use either VSTA or VBA: • customize or extend the features of the software • interact with other applications that use Visual Basic 6 — or with other compatible components that are external to the software • interact with Web-based services • customize the IDE with add-ins • create macro projects — with multi-threading support, if desired • access macro projects programmatically • generate macro code dynamically • store macro code in a pre-compiled format • hide macro code from other macro authors • debug macro projects • create customized user interfaces for macro projects However, if you want to perform any of the following tasks, you must use VSTA: • access the .NET framework natively — to support using Managed Add-in Framework (MAF), referencing .NET assemblies directly, running customized code on the Common Language Runtime (CLR), enforcing .NET security policies, or creating user interfaces by using .NET WinForms • fully customize the IDE • create macro projects that are certified to run on Windows Vista • create macro projects that support 64-bit processors • create macro projects that support server-side customizations • create macro projects that support all data types, including BigDecimal and Int64 • create macro projects and macro assemblies that persist without the use of structured storage • open and modify macro projects in Visual Studio • compile macro projects to DLL assemblies Understanding automation 10 • run macro projects out of process • run macro projects without causing the host application to stop execution at errors or breakpoints • isolate macro projects from one another; run macro projects independently, and stop them during runtime without affecting other running projects • author macros within managed code • prevent servers from running customized user interfaces for macro projects What are the main elements of automation? If you’ve ever developed object-oriented code in C++, Borland Delphi, or Java, you’re already familiar with programming-related concepts such as “objects,” “classes,” “properties,” and “methods.” However, let’s reexamine these terms as they apply to automating Corel DESIGNER, CorelDRAW, and Corel PHOTOPAINT. This section answers the following questions: • What is an object model? (see page 11) • What is a class? (see page 12) • What is a collection? (see page 12) • What is a property? (see page 13) • What is a method? (see page 13) • What is an event? (see page 13) • What is an enumeration? (see page 13) • What is a constant? (see page 14) What is an object model? An object model represents the hierarchy of items (or “objects”) that make up an application and defines the interrelationships of the objects within that hierarchy. In an object model, each object is a child of another object, which is a child of yet another object, and so on. Furthermore, each object in an object model is defined by a property, a method, or an event, or a combination of these items. Besides providing a high level of structure, an object model also lets you use object types (or “classes”) in various ways. For example, a Shape object of type “group” is used to contain other Shape objects, each of which is from type “group” or some other type, such as “rectangle,” “curve,” or “text.” This high level of organization makes the object model easy to use, yet powerful. How is an object model used in automation? Automating Corel DESIGNER, CorelDRAW, or Corel PHOTO-PAINT is accomplished by using the object model of the application to access the various objects in a document and make changes to those objects. In Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT, the Application object represents the top of the object hierarchy: the program itself. All objects are children or grandchildren (or great-grandchildren, and so on) of the application. Understanding automation 11 Starting with the Application object, you can “drill down” through the layers of hierarchy in the object model until you find the desired, and usually the more specific, object. To reference the desired object, you must use a standard notation to separate each level of the object hierarchy. As in many object-oriented languages, the automation environment requires the use of a period or “dot operator” ( . ) to indicate that the object on the right is a member (or child) of the object on the left. Application.Documents(1).Pages(1).Layers(1).Shapes(1).Name = "ABC" An object requires its full hierarchical (or “fully qualified”) reference unless a shortcut is available to it (or unless it has an implicit or implied meaning). An object shortcut is merely a syntactic replacement for the long-hand version of an object. For example, the shortcut object ActiveLayer replaces the long-hand version Application.ActiveDocument.ActivePage.ActiveLayer, while the object shortcut ActiveSelection replaces the long-hand version Application.ActiveDocument.Selection. For more information on object shortcuts, see “How are object shortcuts used?” on page 22. What is a class? A class is the definition or description of an object. A class outlines the properties, methods, and events that apply to a type of object in an application; it acts as a template for all objects of that type class. To use a metaphor, the class “car” is a small vehicle with an engine and four wheels. An object is an instance of a class. To extend the car metaphor, the actual, physical car purchased for the purposes of driving is an object (that is, an instance of the class “car”). In the context of Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT, each open document is an instance of the Document class, each page in the document is an instance of the Page class, and each layer (and each shape on each layer) are more instances of more classes. For example, Document represents the Document class in the software program. However, ActiveDocument represents an object within that class because it makes specific reference to one object. As previously discussed, objects are often made up of other smaller objects. For example, a car contains four objects of the class “wheel,” two objects of the class “headlight,” and so on. Each of these child objects has the same properties and methods of its class-type. This parent/child relationship of objects is an important one to recognize, particularly when referencing an individual object. Some classes “inherit” features from their parents. For example, in the context of Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT, the Shape type has many subtypes (or “inherited types”), including Rectangle, Ellipse, Curve, and Text. All these subtypes can make use of the basic members of the Shape type, including methods for moving and transforming the shape and for setting its color. However, the subtypes also have their own specialist members; for example, a Rectangle can have corner radii, whereas Text has an associated Font property. What is a collection? A collection is similar to an array of objects; it is an object that contains a group of objects that are similar in type. These objects share the same properties, methods, and events, and they are uniquely identified within the collection by their index number or their name. Collection objects act in the same manner and are always plural. Understanding automation 12 For example, Documents represent the Documents collection class in the software program. However, Documents.Item (1) references the first Document object in that collection. What is a property? A property is like an adjective in that it represents an attribute or characteristic quality of an object. Properties can be returned or set, or they can be read-only. Most classes have properties. As an illustration, the properties of the class “car” are that it is small, it has an engine, and it has four wheels. Every instance of the class “car” (that is, every object in that class) also has properties such as color, speed, and number of seats. Read-only properties are fixed by the design of the class; for example, the number of wheels or seats does not (usually) vary from car to car. However, other properties can be changed after the object has been created; for example, the speed of the car can go up and down, and, with a bit of help, its color can be changed. In the context of Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT, Document objects have a name, a resolution, and horizontal and vertical ruler units; individual shapes have outline properties and fill properties, as well as a position and a rotation factor; and text objects have text properties, which may include the text itself. For example, ActiveDocument.Name represents the Name property of a Document object; it specifies the name of the active document. What is a method? A method is like a verb in that it represents an action that can be performed by or on an object. In the example of a class “car,” the car can be made to go faster and slower, so two methods for the class are “accelerate” and “decelerate.” In the context of Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT, documents have methods for creating new pages, layers have methods for creating new shapes, and shapes have methods for applying transformations and effects. For example, ActiveDocument.Close represents the Close method of a Document object; it closes the active document. What is an event? An event is like a noun in that it represents an action that takes place within an object. An event is triggered by an action, such as a mouse click, a key press, or a system timer. An event can be coded to trigger appropriate response in its object. For example, the ActiveDocument.AfterSave event triggers an action in the Document object after it has been saved. What is an enumeration? An enumeration (also called an “enumerated type”) represents a fixed value in the procedures and functions of the coding for a macro. Whereas a variable temporarily stores a changing data value, the value of an enumeration does not change. Understanding automation 13 What is a constant? A constant is an instance of an enumeration, and an enumeration groups similar constants together. For example, AddinFilter is an enumeration, yet it contains several constants, including AddinFilterNone and AddinFilterNew. How is automation coding structured? Your programming knowledge should help you learn to automate the software, regardless of your level of experience with Microsoft Visual Basic for Applications (VBA) or Microsoft Visual Studio Tools for Applications (VSTA). This section answers the following questions on the structure and syntax of the VBA language: • How are variables declared? (see page 14) • How are functions and subroutines built? (see page 16) • How are lines ended? (see page 16) • How are comments included? (see page 17) • How are memory pointers used, and how is memory allocated? (see page 17) • How is scope defined? (see page 18) • How are Boolean comparisons and assignments used? (see page 18) • How are logical and bitwise operators used? (see page 19) • How are message boxes and input boxes provided? (see page 19) • How are objects referenced? (see page 20) • How are collections referenced? (see page 20) • How are object shortcuts used? (see page 22) • How are event handlers provided? (see page 23) The Macro Editor formats all VBA coding for you (see “Formatting code automatically” on page 33). The only way to customize the formatting is to change the size of the indentations. VBA can be used to create object-oriented classes. However, this function is a feature of the programming language and is therefore not discussed in detail in this documentation. How are variables declared? In VBA, the construction for declaring variables is as follows: Dim foobar As Integer The built-in data types are Byte, Boolean, Integer, Long, Single, Double, String, Variant, and several other less-used types including Date, Decimal, and Object. Variables can be declared anywhere within the body of a function, or at the top of the current module. However, it is generally a good idea to declare a variable before it is used; otherwise, the compiler interprets it as a Variant, and inefficiencies can be incurred at run time. Understanding automation 14 Booleans take False to be 0 and True to be any other value, although converting from a Boolean to a Long results in True being converted to a value of –1. To get more information about one of the built-in data types, type it in the Code window of the Macro Editor, select it, and then press F1. Data structures can be built by using the following VBA syntax: Public Type fooType item1 As Integer item2 As String End Type Dim myTypedItem As fooType The items within a variable declared as type fooType are accessed by using dot notation: myTypedItem.item1 = 5 How are strings declared? Using strings is much simpler in VBA than in C. In VBA, strings can be added together, truncated, searched forwards and backwards, and passed as simple arguments to functions. To add two strings together in VBA, simply use the concatenation operator ( & ) or the addition operator ( + ): Dim string1 As String, string2 As String string2 = string1 & " more text" + " even more text" In VBA, there are many functions for manipulating strings, including InStr(), Left(), Mid(), Right(), Len(), and Trim(). How are enumerations declared? To declare an enumeration in VBA, use the following construction: Public Enum fooEnum ItemOne ItemTwo ItemThree End Enum By default, the first item in an enumerated type is assigned a value of 0. How are arrays declared? To declare an array in VBA, use parentheses — that is, the ( and ) symbols: Dim barArray (4) As Integer The value defines the index of the last item in the array. Because array indexes are zero-based by default, there are five elements in the preceding sample array (that is, elements 0 thru 4, inclusive). Understanding automation 15 Arrays can be resized by using ReDim. For example, the following VBA code adds an extra element to barArray but preserves the existing contents of the original five elements: ReDim Preserve barArray (6) Upper and lower bounds for an array can be determined at run time by using the functions UBound() and LBound(). Multidimensional arrays can be declared by separating the dimension indexes with commas, as in the following VBA example: Dim barArray (4, 3) How are functions and subroutines built? VBA uses both functions and subroutines (or “subs”). Functions can be used to return a value, but subs cannot. In VBA, functions and subs do not need to be declared before they are used, nor before they are defined. In fact, functions and subs need to be declared only if they actually exist in external system DLLs. Typical functions in a language such as Java or C++ can be structured as follows: void foo( string stringItem ) { // The body of the function goes here } double bar( int numItem ) { return 23.2; } In VBA, however, functions are structured as in the following example: Public Sub foo (stringItem As String) ' The body of the subroutine goes here End Sub Public Function bar (numItem As Integer) As Double bar = 23.2 End Function To force a function or sub to exit immediately, you can use Exit Function or Exit Sub (respectively). How are lines ended? In VBA, each statement must exist on its own line, but no special character is required to denote the end of each line. (In contrast, many other programming languages use a semicolon to separate individual statements.) To break a long VBA statement over two or more lines, each of the lines (other than the last line) must end with an underscore ( _ ) preceded by at least one space: newString = fooFunction ("This is a string", _ 5, 10, 2) You can combine several statements in a single VBA line by separating them with colons: a = 1 : b = 2 : c = a + b Understanding automation 16 A VBA line cannot end with a colon. VBA lines that end with a colon are labels that are used by the Goto statement. How are comments included? Comments in VBA — similarly to in ANSI, C++, and Java — can be created only at the end of a line. Comments begin with an apostrophe ( ' ) and terminate at the end of the line. Each line of a multi-line comment must begin with its own apostrophe in VBA: a = b ' This is a really interesting piece of code that ' requires so much explanation that I needed to break ' the comment over multiple lines. To comment out large sections of VBA code, use the following syntax (similarly to in C or C++): #If 0 Then ' That's a zero, not the letter 'oh'. ' All this code will be ignored by ' the compiler at run time! #End If How are memory pointers used, and how is memory allocated? VBA does not support C-style memory pointers. Memory allocation and garbage collection are automatic and transparent, just as in Java and JavaScript (and some C++ code). How are arguments passed? Most languages, including C++ and Java, pass an argument to a procedure as a copy of the original. If the original must be passed, then one of two things can happen: • a memory pointer is passed that directs the procedure to the original argument in memory • a reference to the original argument is passed Microsoft Visual Basic (VB) has the same requirements for passing arguments. In VB, passing a copy of the original argument is called “passing by value” and passing a reference to the original is called “passing by reference.” By default, function and subroutine parameters are passed by reference. A reference to the original variable is passed in the argument of the procedure; changing the value of that argument, in effect, changes the value of the original variable value as well. In this way, more than one value can be returned from a function or subroutine. To explicitly annotate the code to indicate that an argument is being passed by reference, you can prefix the argument with ByRef. If you want to prevent a procedure from changing the value of the original variable, you can force the copying of an argument. To do this in VBA, prefix the argument with ByVal, as shown in the example that follows. The functionality of ByRef and ByVal is similar to the ability of C and C++ to pass a copy of a variable, or to pass a pointer to the original variable. Understanding automation 17 Private Sub fooFunc (ByVal int1 As Integer, _ ByRef long1 As Long, _ long2 As Long) ' Passed ByRef by default In the preceding VBA example, arguments long1 and long2 are both, by default, passed by reference. Modifying either argument within the body of the function modifies the original variable; however, modifying int1 does not modify the original because it is a copy of the original. How is scope defined? You can define the scope of a data type or procedure (or even an object). Data types, functions, and subroutines (and members of classes) that are declared as private are visible only within that module (or file). By contrast, functions that are declared as public are visible throughout all the modules; however, you may need to use fully qualified referencing if the modules are almost out of scope — for example, if you are referencing a function in a different project. Unlike C, VBA does not use braces — that is, the { and } symbols — to define local scope. Local scope in VBA is defined by an opening function or subroutine definition statement (that is, Function or Sub) and a matching End statement (that is, End Function or End Sub). Any variables declared within the function are available only within the scope of the function itself. How are Boolean comparisons and assignments used? In Microsoft Visual Basic (VB), Boolean comparison and Boolean assignment are both performed by using a single equals sign ( = ): If a = b Then c = d By contrast, many other languages use a double equals sign for Boolean comparison and a single equals sign for Boolean assignment: if( a == b ) c = d; The following code, which is valid in C, C++, Java, and JavaScript, is invalid in VBA: if( ( result = fooBar( ) ) == true ) The preceding example would be written in VBA as the following: result = fooBar( ) If result = True Then For other Boolean comparisons, VBA uses the same operators as other languages (except for the operators for “is equal to” and “is not equal to”). All the Boolean-comparison operators are provided in the following table. Comparison VBA operator C-style operator Is equal to = == Is not equal to <> != Is greater than > > Is less than < < Understanding automation 18 Comparison VBA operator C-style operator Is greater than or equal to >= >= Is less than or equal to <= <= The result of using a Boolean operator is always either True or False. How are logical and bitwise operators used? In VBA, logical operations are performed by using the keywords And, Not, Or, Xor, Imp, and Eqv, which perform the logical operations AND, NOT, OR, Exclusive-OR, logical implication, and logical equivalence (respectively). These operators also perform Boolean comparisons. The following code shows a comparison written in C or a similar language: if( ( a && b ) || ( c && d ) ) This example would be written as follows in VBA: If ( a And b ) Or ( c And d ) Then Alternatively, the preceding VBA code could be written in the following full long-hand form: If ( a And b = True ) Or ( c And d = True ) = True Then The following table provides a comparison of the four common VBA logical and bitwise operators, and the Cstyle logical and bitwise operators that are used by C, C++, Java, and JavaScript. VBA operator C-style bitwise operator C-style Boolean operator And & && Not ~ ! Or | || Xor ^ How are message boxes and input boxes provided? In VBA, you can present simple messages to the user by using the MsgBox function: Dim retval As Long retval = MsgBox("Click OK if you agree.", _ vbOKCancel, "Easy Message") If retval = vbOK Then MsgBox "You clicked OK.", vbOK, "Affirmative" End If Understanding automation 19 You can also get strings from the user by using InputBox function: Dim inText As String inText = InputBox("Input some text:", "type here") If Len(inText) > 0 Then MsgBox "You typed the following: " & inText & "." End If If the user clicks Cancel, the length of the string returned in inText is zero. For information on creating more complex user interfaces, see “Making macros user-friendly” on page 56. How are objects referenced? If you want to create a reference to an object so that you can treat that reference like a variable (sh, in the following VBA example for Corel DESIGNER and CorelDRAW), you can use the Set keyword. Dim sh As Shape Set sh = ActiveSelection.Shapes.Item(1) After you create this reference, you can treat it as though it were the object itself. sh.Outline.Color.GrayAssign 35 If the selection is changed while sh is still in scope, sh references the original shape from the old selection and is unaffected by the new selection. You cannot simply assign the object to the variable as in the following example: Dim sh As Shape sh = ActiveSelection.Shapes.Item(1) To release an object, you must set its reference value to Nothing. Set sh = Nothing You can also test whether a variable references a valid object by using the Nothing keyword. If sh Is Nothing Then MsgBox "sh is de-referenced." Objects do not need to be explicitly released. In most cases, VB releases the object upon disposal of the variable when you exit the function or subroutine. How are collections referenced? Many objects are members of collections. A collection is similar to an array, except that it contains objects rather than values. However, members of collections can be accessed in the same way as arrays. For example, a collection that is used frequently in Corel DESIGNER and CorelDRAW is the collection of shapes on a layer: The object ActiveLayer references either the current layer or the layer that is selected in the Object Manager docker. Corel DESIGNER and CorelDRAW contains many collections: A document contains pages, a page contains layers, a layer contains shapes, a curve contains subpaths, a subpath contains segments and nodes, a text range contains lines and words, a group contains shapes, and the application contains windows. All these collections are handled by VBA in the same way. Understanding automation 20 How are the items in a collection referenced? To reference the shapes on a layer, the collection of shapes for that layer is used: ActiveLayer.Shapes. To reference the individual shapes in the collection, the Item() property is used. Here is a VBA example for Corel DESIGNER and CorelDRAW: Dim sh As Shape Set sh = ActiveLayer.Shapes.Item(1) Most elements of a collection start at 1 and increase. For the collection ActiveLayer.Shapes, Item(1) is the item at the “top” or “front” of the layer — in other words, it is the item that is in front of all other shapes. Furthermore, because each item in the ActiveLayer collection is an object of type Shape, you can reference any item in VBA merely by appending the appropriate dot-notated member: ActiveLayer.Shapes.Item(1).Outline.ConvertToObject Sometimes, individual items have names. If the item you are looking for has an associated name (and you know what the name is and which collection the item is in), you can use that name to reference the item directly, as in the following VBA example for Corel DESIGNER and CorelDRAW: Dim sh1 As Shape, sh2 As Shape Set sh1 = ActiveLayer.CreateRectangle(0, 5, 7, 0) sh1.Name = "myShape" Set sh2 = ActiveLayer.Shapes.Item("myShape") Also, because an item is usually the implied or default member of a collection, it is not strictly required. For this reason, the last line of the preceding VBA code can be rewritten as follows: Set sh2 = ActiveLayer.Shapes("myShape") How are the items in a collection counted? All collections have a property called Count. This read-only property gives the number of members in the collection, as in the following VBA example for Corel DESIGNER and CorelDRAW: Dim count As Long count = ActiveLayer.Shapes.Count The returned value is not only the number of items in the collection: Because the collection starts from 1, it is also the index of the last item. How are the items in a collection parsed? It is often necessary to parse through the members of a collection to check or change the properties of each item. By using the Item() and Count members, it is straightforward to step through a collection of items. With each iteration, it is possible to test the properties of the current item, or to call its methods. Understanding automation 21 The following VBA code for Corel DESIGNER and CorelDRAW restricts all shapes on the layer to no wider than ten units: Dim I As Long, count As Long count = ActiveLayer.Shapes.Count For I = 1 to count If ActiveLayer.Shapes.Item(i).SizeWidth > 10 Then ActiveLayer.Shapes.Item(i).SizeWidth = 10 End If Next I There is, however, a more convenient way of parsing a collection in VBA. Instead of using the Count property and a For-Next loop, this technique uses a For-Each-In loop: Dim sh As Shape For Each sh In ActiveLayer.Shapes If sh.SizeWidth > 10 Then sh.SizeWidth = 10 End If Next sh If you want to copy the selection and then parse it later when it is no longer selected, copy the selection into a ShapeRange object: Dim sr As ShapeRange Dim sh As Shape Set sr = ActiveSelectionRange For Each sh In sr ' Do something with each shape Next sh How are object shortcuts used? Shortcuts are provided for some frequently accessed objects. Using shortcuts requires less typing, so shortcuts are easier to use than their longhand versions. (Also, using shortcuts can improve run-time performance because the compiler does not need to determine every object in a long dot-separated reference.) For Corel DESIGNER and CorelDRAW, a shortcut can be used on its own as a property of the Application object. The following table provides these shortcuts and their long forms. (For a description of any item, see the “Object Model Reference” section of the Macros Help file for Corel DESIGNER [des_om.chm] or CorelDRAW [draw_om.chm].) Shortcut Long form ActiveLayer ActivePage.ActiveLayer ActivePage ActiveDocument.ActivePage Understanding automation 22 Shortcut Long form ActiveSelection ActiveDocument.Selection ActiveSelectionRange ActiveDocument.SelectionRange ActiveShape ActiveDocument.Selection.Shapes(1) ActiveView ActiveWindow.ActiveView ActiveWindow ActiveDocument.ActiveWindow For Corel PHOTO-PAINT, a shortcut can be used on its own as a property of the Corel PHOTO-PAINT Application object. The following table provides these shortcuts and their long forms. (For a description of any item, see the “Object Model Reference” section of the Corel PHOTO-PAINT Macros Help file [pp_om.chm].) Shortcut Long form ActiveLayer ActivePage.ActiveLayer ActiveWindow ActiveDocument.ActiveWindow For Corel DESIGNER and CorelDRAW, the following shortcuts can also be used as members of a given Document object: • • • • ActiveLayer ActivePage ActiveShape ActiveWindow For Corel PHOTO-PAINT, the following shortcuts can also be used as members of a given Document object: • ActiveLayer • ActiveWindow For Corel DESIGNER and CorelDRAW, the Document object also has the properties Selection and SelectionRange, which let you get the selection or selection range (respectively) from a specified document regardless of whether that document is active. How are event handlers provided? While running, Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT raise various events to which macros can respond through the use of event handlers — subroutines with specific, defined names. Each macro project defines its event handlers in one of the following code modules: • ThisMacroStorage — for macro projects that are stored in Global Macro Storage (GMS) files • ThisDocument — for macro projects that are stored in documents The GlobalMacroStorage object is a virtual object that represents each and all open documents. The GlobalMacroStorage object has several events that are raised at the time of any event, such as opening, printing, saving, or closing a document (although the range of events is actually greater than this because each one has a “before” and “after” event). Understanding automation 23 To respond to an event, you must provide an event handler — a subroutine in any ThisMacroStorage module with a specific name for which the application is pre-programmed to search. However, the application does check all ThisMacroStorage modules in all installed projects; for this reason, you can create an event-driven solution and distribute it as a single project file just as you would provide any other solution. Each project can have only one ThisMacroStorage module, and it is automatically created when the project is first created. In VBA, you can add event handlers to a ThisMacroStorage module by using the Macro Editor. For example, a Corel DESIGNER or CorelDRAW macro solution may need to respond to the closing of a document by logging the closure in a file as part of a workflow-management system. To respond to the opening of a document, the solution must respond to the OpenDocument event for the GlobalMacroStorage class. To create this event handler in VBA, do the following: • Open a ThisMacroStorage module for editing in the Macro Editor. • Next, choose GlobalMacroStorage from the Object list box at the top of the Code window, and then choose DocumentOpen from the Procedure list box. The Macro Editor creates a new, empty subroutine called GlobalMacroStorage_DocumentOpen()— or, if that subroutine already exists, the Macro Editor places the cursor into it. To then add the name of the opened file to the log, you need only write some code. To reduce the size of the ThisMacroStorage module, you can assign this event-logging task to a public subroutine in another module. This technique lets the run-time interpreter more easily parse all the ThisMacroStorage modules each time an event is raised. The following VBA code illustrates this example for Corel DESIGNER and CorelDRAW: Private Sub GlobalMacroStorage_OpenDocument(ByVal Doc As Document, _ ByVal FileName As String) Call LogFileOpen(FileName) End Sub Here is a small sample of the events available in Corel DESIGNER and CorelDRAW: Event Description Start Raised when the user starts the application DocumentNew Raised when a document is created; passes a reference to the document DocumentOpen Raised when a document is opened; passes a reference to the document DocumentBeforeSave Raised before a document is saved; passes the file name of the document as a parameter DocumentAfterSave Raised after a document is saved; passes the file name of the document as a parameter DocumentBeforePrint Raised before the Print dialog box is displayed DocumentAfterPrint Raised after a document is printed SelectionChange Raised when a selection changes DocumentClose Raised before a document is closed Understanding automation 24 Event Description Quit Raised when the user quits the application Event handlers for frequent events — such as events related to the Shape class — should be as efficient as possible, to keep the application running as quickly as possible. Understanding automation 25 Getting started with macros Now that you understand a bit about automation, you’re ready to get started with macros. This section provides an overview of the macro-related tools and features of Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT. This section contains the following topics: • “Setting up the automation feature” on page 26 • “Using the Macros toolbars” on page 27 • “Using the Macro Manager docker” on page 28 • “Using the Add-in Manager” on page 29 • “Using the Macro Editor” on page 30 • “Using the VSTA Editor” on page 42 Setting up the automation feature Before you can develop and run macros in the software, you may need to set up the automation features for VBA and VSTA. When you perform a “typical installation” of the software, the VBA and VSTA features are installed by default. However, you can manually install them if necessary. You can also specify various options for VBA. For details on setting up the automation feature, see the following procedures: • “To install the VBA and VSTA features” on page 26 • “To specify VBA options” on page 27 To install the VBA and VSTA features 1 Insert the installation disc into your computer. If the installation wizard does not start automatically, locate and run the Setup.exe file on the installation disc. 2 Follow the on-screen instructions for modifying the software. 3 On the Features page of the setup, enable the following check boxes in the Utilities list box: • Visual Basic for Applications 6.4 • Visual Studio Tools for Applications Corel DESIGNER Technical Suite X5 Macro Programming Guide 26 To specify VBA options 1 Click Tools ` Options. 2 In the Workspace list of categories, click VBA. 3 In the Security area, specify how to control the risk of running malicious macros by clicking Security options. If you want to bypass this security feature, enable the Trust all installed GMS modules check box, and then proceed to step 6. 4 On the Security level page of the Security dialog box, enable one of the following options: • Very high — allows only macros installed in trusted locations to run. All other signed and unsigned macros are disabled. • High — allows only signed macros from trusted sources to run. Unsigned macros are automatically disabled. • Medium — lets you choose which macros run, even if they are potentially harmful. • Low (not recommended) — allows all potentially unsafe macros to run. Enable this setting if you have virus-scanning software installed, or if you check the safety of all documents that you open. 5 On the Trusted publishers page of the Security dialog box, review which macro publishers are trusted. Click View to display details on the selected macro publisher, or click Remove to delete the selected macro publisher from the list. If desired, you can enable or disable the Trust access to Visual Basic project check box for the selected macro publisher. 6 Disable the Delay load VBA check box if you want to load the VBA feature at start-up. Using the Macros toolbars Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT feature a Macros toolbar that provides easy access to several macro-related featues, such as the Macro Editor. The Macros toolbar in Corel DESIGNER and CorelDRAW The Macros toolbar in Corel PHOTO-PAINT Using the Macros toolbar in Corel DESIGNER and CorelDRAW In Corel DESIGNER and CorelDRAW, the Macros toolbar features the following buttons: • Macro Manager button • Run Macro button • Macro Editor button — opens the Macro Manager docker — runs a macro — opens the Macro Editor Getting started with macros 27 • Disable application events button running macros • Start Recording button • Pause Recording button • Stop Recording button — switches the Macro Editor between its modes for designing and — records a macro — pauses the recording of a macro — stops the recording of a macro To display the Macros toolbar in Corel DESIGNER and CorelDRAW, click Window ` Toolbars ` Macros. A check mark next to the command indicates that the toolbar is displayed. Using the Macros toolbar in Corel PHOTO-PAINT In Corel PHOTO-PAINT, the Macros toolbar features the following buttons: • Macro Manager button • Run Macro button • Macro Editor button — opens the Macro Manager docker — runs a macro — opens the Macro Editor • Disable application events button running macros — switches the Macro Editor between its modes for designing and To display the Macros toolbar in Corel PHOTO-PAINT, click Window ` Toolbars ` Macros. A check mark next to the command indicates that the toolbar is displayed. Using the Macro Manager docker In Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT, macros are stored in code modules, which are stored in macro projects. The Macro Manager docker provides a list of all existing VBA macro projects, plus the code modules and macros that are stored in them. You can use the Macro Manager docker to perform various tasks related to macro projects, code modules, and macros (see “Creating macros” on page 44). The Macro Manager docker in Corel DESIGNER and CorelDRAW, with a macro selected Getting started with macros 28 The Macro Manager docker in Corel PHOTO-PAINT, with a macro selected To display the Macro Manager docker, do one of the following: • Click Tools ` Macros ` Macro Manager. • Click the Macro Manager button on the Macros toolbar. Using the Add-in Manager An add-in is a separate module that extends the functionality of an application. The Add-in Manager for Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT displays a list of all registered add-ins for the application. The Add-in Manager To open the Add-in Manager, click Tools ` Macros ` Add-in Manager. You can then use the Add-in Manager to perform various tasks related to add-ins. To Do the following Display the description for an add-in Select the add-in Load an add-in Select the add-in, enable the Loaded/Unloaded check box, and then click OK Getting started with macros 29 To Do the following Load an add-in each time the application is started Select the add-in, enable the Load on startup check box, and then click OK Unload an add-in Select the add-in, disable the Loaded/Unloaded check box, and then click OK You can use a registered add-in by clicking Tools ` Macros ` Add-ins and then choosing the add-in. Using the Macro Editor Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT provide an integrated development environment (IDE) for creating VBA macro projects. Called the Macro Editor, this IDE is similar to the one included with the full version of Visual Basic. You can use the Macro Editor to perform various tasks related to VBA macros, such as the following: • browsing the contents of a VBA macro project • developing and debugging VBA macro code • setting object properties for VBA macros • creating dialog boxes or “forms” for VBA macros You cannot use the Macro Editor to compile executable (EXE) program files. The Macro Editor features three main areas: • Project Explorer — lets you browse macro projects and their contents. For more information, see “Using the Project Explorer” on page 31. • Code window — lets you work with macro code. For more information, see “Using the Code window” on page 32. • Properties window — lists all editable properties for the selected object. For more information, see “Using the Properties window” on page 36. The Macro Editor also features four main toolbars: • Standard toolbar — is the default toolbar • Debug toolbar — contains buttons for common debugging tasks • Edit toolbar — contains buttons for common code-editing tasks • UserForm toolbar — contains buttons specific to designing dialog boxes For more information on these toolbars, see “Using the Macro Editor toolbars” on page 36. Getting started with macros 30 4 5 1 2 6 3 7 The Macro Editor features the following: 1) Project Explorer; 2) Code window; 3) Properties window; 4) Standard toolbar; 5) Debug toolbar; 6) Edit toolbar; 7) UserForm toolbar The Macro Editor also lets you access the Object Browser, which displays the entire object model of each referenced component and of the host application. For more information, see “Using the Object Browser” on page 37. Although the Macro Editor opens in a separate window from its host application, it runs within the process of that application. To display the Macro Editor, do any of the following: • Click Tools ` Macros ` Macro Editor on the main menu in the application. • Click the Macro Editor button on the Macros toolbar. • Right-click Visual Basic for Applications in the Macro Manager docker, and then click Show IDE. • Press Alt + F11. To switch between the Macro Editor and the application, use the Windows taskbar, or press Alt + F11 or Alt + Tab. For more detailed information on constructing code procedures and setting properties, please see the Microsoft Visual Basic for Applications Help file, which is available from the Help menu in the Macro Editor. Using the Project Explorer The Project Explorer is essential for navigating macro projects and their contents: documents and objects, forms, modules, and class modules (or “classes”). Getting started with macros 31 Each type of component in the Project Explorer has an icon assigned to it: Icon Item macro project folder document or object (Corel DESIGNER) document or object (CorelDRAW) document or object (Corel PHOTO-PAINT) form module class module (or “class”) To display or hide the Project Explorer, do any of the following: • Click View ` Project Explorer. • Click the Project Explorer button • Press Ctrl + R. on the Standard toolbar. Using the Code window The Code window is where you spend most of your time when working on macros. A standard code editor in the style of Microsoft Visual Studio, the Code window lets you do the following: • format code automatically Getting started with macros 32 • • • • color syntax automatically check syntax automatically jump to definitions use contextual pop-up lists and automatic completion If you are already familiar with any of the Microsoft Visual Studio editors, the Code window will be entirely familiar to you. The Code window To display the Code window, do one of the following: • Click View ` Code. • Press F7. Formatting code automatically The Macro Editor formats code automatically for you. Even the capitalization of keywords, functions, subroutines, and variables is taken care of by the Macro Editor, irrespective of what you type. You cannot custom-format code, although you can set the indentation for each line, as well as the placing of custom line breaks. If you use the returned value when calling a function, the parentheses around the parameters are mandatory (just as in most modern programming languages): a = fooFunc (b, c) However, if the returned value from a function call is being discarded, or if you are calling a subroutine, the parentheses must be left out (unlike in most other languages): barFunc d, e fooBarSub f Getting started with macros 33 If you prefer always to see the parentheses, use the Call keyword before the function call or subroutine call: Call barFunc (d, e) Call fooBarSub (f) Coloring syntax automatically As you develop code in the Code window, the Macro Editor colors each word according to its classification. Word color Classification Blue Automation keyword or programming statement Green Comment Black All other text The Code window also uses the following colorization techniques: Colorization technique Classification Red text Line of code containing errors White text on blue background Selected text Text highlighted in yellow Line where execution is paused for debugging White text on red background and red dot in the left margin Breakpoint set for debugging purposes Blue dot in the left margin Bookmark set in the code For more information, see “Setting breakpoints” on page 54. These syntax-colorization techniques make the code much easier to read. Syntax coloring and highlighting Breakpoints and bookmarks are lost when you quit the application. The Macro Editor lets you modify the default colors for syntax highlighting. Click Tools ` Options, and choose your settings on the Editor Format page. Getting started with macros 34 Checking syntax automatically Every time you move the cursor out of a line of code, the Macro Editor checks the syntax of the code in that line; if an error is found, the line is colored red and a pop-up warning is displayed. This real-time checking is useful (particularly when you are learning to program macros) because it indicates many possible errors in the code without having you run the code. The Macro Editor lets you disable pop-up warnings. Click Tools ` Options, click the Editor tab, and then disable the Auto Syntax Check check box. Although the Macro Editor still checks the syntax and colors erroneous lines red, it stops displaying a warning when you paste text from another line of code. Jumping to definitions The Macro Editor lets you jump directly to the definition of a variable, function, or object. Desired definition Procedure Destination Variable Right-click the variable in the Code window, and then click Definition. The definition of the variable in the code Function Right-click the function in the Code window, and then click Definition. The definition of the function in the code Object Right-click the object in the Code window, and then click Definition. The definition of the object in the Object Browser To return to where you requested the definition, right-click anywhere in the Code window, and then click Last Position. Using contextual pop-up lists for automatic completion The Macro Editor adds the functions you write and the variables you define to an internal list that contains all built-in keywords and enumerated values. As you type, the Macro Editor displays a contextual list of words that are valid candidates for insertion at the current position. This auto-completion feature makes code development quicker and more convenient. An auto-completion pop-up list Getting started with macros 35 If you type the first few characters of the word you want to use, the pop-up list advances to the nearest candidate that matches those characters. Select the desired word, and then do one of the following: • type the character to follow the word (typically a space, line feed, parenthesis, period, or comma) • enter only the word by pressing Tab or Ctrl + Enter To force the pop-up menu display, press Ctrl + Spacebar; the menu scrolls to the word that most closely matches the characters that you have typed so far. This technique is particularly useful for filling parameter lists when calling a function or subroutine. If there is only one exact match, the Macro Editor inserts the word without popping up the list; to display the pop-up list for the selected keyword at any time without auto-filling it, press Ctrl + J. Using the Properties window The Properties window lists all editable properties for the selected object. Many macro objects — including projects, modules, and forms and their controls — have property sheets that can be modified. The Properties window, with the properties of a form displayed The Properties window is automatically updated when you select an object, or when you change the properties of the selected object by using other methods (for example, by using the mouse to move and resize form controls). To display or hide the Properties window, do any of the following: • Click View ` Properties Window. • Click the Properties Window button • Press F4. on the Standard toolbar. Using the Macro Editor toolbars The Macro Editor features four toolbars — Standard, Debug, Edit, and UserForm — that you can use to perform macro-related tasks. The Standard toolbar is the default toolbar. The Standard toolbar Getting started with macros 36 The Debug toolbar contains buttons for common debugging tasks (see “Debugging macros” on page 52). The Debug toolbar The Edit toolbar contains buttons for common code-editing tasks. The Edit toolbar The UserForm toolbar contains buttons specific to designing dialog boxes (see “Designing dialog boxes” on page 60). The UserForm toolbar To display or hide a toolbar, click View ` Toolbars, and then click the corresponding command. A check mark next to a command indicates that its toolbar is currently displayed. You can “float” a toolbar by dragging it from the menu bar. You can dock a toolbar by dragging it to the menu bar. Using the Object Browser The Object Browser is one of the most useful tools that is provided by the Macro Editor. In an easy-to-use, structured format, the Object Browser displays the entire object model of each referenced component and, most importantly, of Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT. Referenced components include all ActiveX or Object Linking and Embedding (OLE) objects that are used by the project. The Object Browser window features the following items: • Project/Library list box — lists all referenced components (projects and libraries). Choosing a project or library from this list updates the Object Browser to display only the items for that project or library. Generally, displaying only one project or library at a time makes it easier to use the Object Browser. • navigation buttons — let you cycle through your selections from the Object Browser • Copy to Clipboard button — copies the current selection to the Clipboard • View Definition button — displays where the current selection is defined in the Code window • Help button — displays a Help topic for the current selection. You can also access this Help topic by pressing F1. • search controls — let you search the selected project or library for a given string. For more information, see “Using the search controls” on page 42. • Search Results window — displays the results of a search. For more information, see “Using the search controls” on page 42. • Class list — displays all class-related items for the selected project or library. For more information, see “Using the Class list” on page 38. Getting started with macros 37 • Member list — displays the members of the selected class. For more information, see “Using the Member list” on page 39. • Information window — displays information about the selected class or class member. For more information, see “Using the Information window” on page 41. navigation buttons Project/ Library list box Help button search controls Search Results window View Definition button Class list Copy to Clipboard button Member list Information window The Object Browser window To open the Object Browser from within the Macro Editor, do any of the following: • Click View ` Object Browser. • Click the Object Browser button • Press F2. on the Standard toolbar. To reference the object model of another application, click Tools ` References. Referenced components can be accessed by the macro code. Using the Class list Every project and library has an object model that contains the following class-related items, which are displayed in the Class list: • global values • classes • modules • types • enumerations Global values apply to an entire project or library, and they include individual members from enumerations (such as text-paragraph alignments, shape types, and import/export filters). Classes contain properties, methods, and events. For more information, see “What is a class?” on page 12. Getting started with macros 38 For documentation on all classes available to Corel DESIGNER, CorelDRAW, or Corel PHOTOPAINT, see the “Object Model Reference | Classes” section of the Macros Help file for the application. Modules contain macro code. For documentation on all modules available to Corel DESIGNER or CorelDRAW, see the “Object Model Reference | Modules” section of the Macros Help file for the application. Types are customized data types that supplement the built-in data types that are provided by the automation environment (see “How are variables declared?” on page 14). For documentation on all types available to Corel DESIGNER or CorelDRAW, see the “Object Model Reference | Types” section of the Macros Help file for the application. Enumerations represent fixed values in the procedures and functions of the coding for a macro. For more information, see “What is an enumeration?” on page 13. For documentation on all enumerations available to Corel DESIGNER, CorelDRAW, or Corel PHOTOPAINT, see the “Object Model Reference | Enumerations” section of the Macros Help file for the application. Each type of item in the Class list has an icon assigned to it: Icon Item global value class module type enumeration To access the Help topic for a selected item, click the Help button, or press F1. Using the Member list When you choose an item from the Class list, the members of that item appear in the Member list. Class members include the following: • properties • methods • events Getting started with macros 39 • constants A property can be a simple type (such as a Boolean, integer, or string), or it can be a class or enumeration from the Class list. A property that is based on a class from the Class list inherits all members of that class. Many classes have a default property. The default property is implied if no property name is given when getting or setting the value of the parent object. For example, collection types have the default property Item, which can be indexed; in such instances, it is not necessary to specify the Item property. Here, ActiveSelection.Shapes.Item(1).Selected = False is the same as the shorter ActiveSelection.Shapes(1).Selected = False because Item is the default or implied property of a collection of shapes. For documentation on all properties available to Corel DESIGNER, CorelDRAW, or Corel PHOTOPAINT, see the “Object Model Reference | Properties” section of the Macros Help file for the application. Methods are commonly known as “member functions” — functions that a class can perform on itself. A good example is the Move method of the Shape class in Corel DESIGNER and CorelDRAW, which moves a shape by using an [x, y] vector. The following code moves the selected shapes 2 measurement units to the right and 3 measurement units upwards: ActiveSelection.Move 2, 3 If the return value of a function is not used, the function call does not take parentheses around the argument list unless the Call keyword is used. For documentation on all methods available to Corel DESIGNER, CorelDRAW, or Corel PHOTOPAINT, see the “Object Model Reference | Methods” section of the Macros Help file for the application. Events are associated with some classes. You can set up an event handler that is called when that event occurs in the application; this functionality lets you develop sophisticated applications that respond automatically to what is happening within the application. Commonly handled events include the BeforePrint, BeforeSave, PageActivate, SelectionChange, and ShapeMove events of the Document class in Corel DESIGNER and CorelDRAW. For documentation on all events available to Corel DESIGNER, CorelDRAW, or Corel PHOTOPAINT, see the “Object Model Reference | Events” section of the Macros Help file for the application. The constants displayed in the Member list are members of enumerations or are defined as public in a module. Enumerations group related items from a closed list — such as Corel DESIGNER and CorelDRAW shape types, import/export filters, and alignments — for use anywhere an integer value is required. In Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT, many constants begin with cdr (for example, cdrEPS and cdrLeftAlignment), while others begin with clr, cui, pdf, pnt, or prn. Visual Basic also has its own constants, including ones (such as vbKeyEnter) for keystrokes and ones (such as vbOK) for dialog-box buttons. Getting started with macros 40 For documentation on all constants available to Corel DESIGNER, CorelDRAW, or Corel PHOTOPAINT, see the “Object Model Reference | Constants” section of the Macros Help file for the application. Each type of item in the Member list has an icon assigned to it: Icon Item property default property method event constant To access the Help topic for a selected item, click the Help button, or press F1. Using the Information window The Information window provides information about the selected class or class member. This information includes the following: • a prototype of the item • an indication of whether the item is a read-only property • the parent of the item • a short description of the item The Information window for the Document.Application property in Corel PHOTOPAINT The Information window provides hyperlinks to all referenced types and classes that are defined within the current object model. For example, the information for the Document.Application property in Corel PHOTOPAINT (see the preceding figure) includes the following hyperlinks: • Application — accesses the Application class, because Application is both the type of the Document.Application property and a class in the PHOTOPAINT library • PHOTOPAINT — accesses the class for the PHOTOPAINT library, which contains all classes in the Corel PHOTO-PAINT object model • Document — accesses the Document class, which is the parent of the Application property Getting started with macros 41 When the Information window is not tall enough to reveal its complete contents, a scroll bar is provided. To increase the height of the Information window, drag the top border of the window upwards. Using the search controls The search controls let you search the selected project or library for a given string. Searching is useful when you can only partly remember the name of a class or class member, or when you want to find classes and members that have similar names (such as those containing the word “open”). Searching an object model To search the classes and members of the selected object model, type a string into the Search box, and then click the Search button . The Search Results window displays, in alphabetical order, all matches. Clicking a match advances the Class list and Member list to that item and displays the Information window for that item. Matching class names have a blank Member column in the Search Results window. To hide the Search Results window, click the Hide Search Results button . Using the VSTA Editor Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT provide an integrated development environment (IDE) for creating VSTA macro projects. Called the VSTA Editor, this IDE is similar to the Macro Editor (which is the IDE for VBA macro projects in Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT). You can use the VSTA Editor to perform various tasks related to VSTA macros. Getting started with macros 42 By default, the software creates VSTA folders at the following location: • for Corel DESIGNER: My Documents\Corel\VSTA\Corel DESIGNER • for CorelDRAW: My Documents\Corel\VSTA\CorelDRAW • for Corel PHOTO-PAINT: My Documents\Corel\VSTA\Corel PHOTO-PAINT Be sure to load VSTA add-ins from the following location: • for Corel DESIGNER: My Documents\Corel\VSTA\Corel DESIGNER\Addins • for CorelDRAW: My Documents\Corel\VSTA\CorelDRAW\Addins • for Corel PHOTO-PAINT: My Documents\Corel\VSTA\Corel PHOTO-PAINT\Addins You can open the VSTA Editor from within Corel DESIGNER, CorelDRAW, or Corel PHOTO-PAINT. Although the VSTA Editor opens in a separate window, it runs within the process of its host application. To open the VSTA Editor, do any of the following: • Click Tools ` Macros ` VSTA Editor on the main menu in the application. • Press Alt + Shift + F12. To switch between the VSTA Editor and the application, use the Windows taskbar, or press Alt + Shift F12 or Alt + Tab. For more detailed information on VSTA and its programming environment, please consult the Help menu in the VSTA Editor. Getting started with macros 43 Creating macros Now that you are familiar with the concept of automation and with the macro-related tools and features of Corel DESIGNER, CorelDRAW, and Corel PHOTO-PAINT, you are ready to create macros. This section contains the following topics: • “Creating macro projects” on page 44 • “Writing macros” on page 47 • “Recording macros” on page 48 • “Running macros” on page 51 • “Debugging macros” on page 52 Creating macro projects The process of creating a macro begins with creating a macro project. A macro project can be created in one of two ways: • as a Global Macro Storage (GMS), or “project,” file • in a document For best results in storing and distributing a macro project, it is highly recommended that you use a GMS file. GMS files are stored in the GMS folder for the application, which is installed at the following locations: • for macro projects that ship with the software: X:\Program Files\Corel\ \ (where X: is the drive and Program Files\Corel\ is the path where the software is installed, and where is the application subfolder) • for user-created macro projects on Windows 7 and Windows Vista®: X:\Users\ \AppData\Roaming\Corel\ \ (where X: is the drive where the software is installed, is the name of the user, is the folder where the software is installed, and is the application subfolder) • for user-created macro projects on Windows XP: X:\Documents and Settings\ \Application Data\Corel\ \ (where X: is the drive where the software is installed, is the name of the user, is the folder where the software is installed, and is the application subfolder) The Macro Manager docker provides basic tools for working with macro projects. For access to more advanced tools, you can use the Macro Editor (for VBA macro projects) or the VSTA Editor (for VSTA macro projects). Corel DESIGNER Technical Suite X5 Macro Programming Guide 44 In the Macro Editor, a VBA macro project is broken into four types of components, which are displayed as the following folders in the Project Explorer (see “Using the Project Explorer” on page 31): • Objects — contains a single item that is used mostly for event handling: ThisMacroStorage for GMS-based macro projects, or ThisDocument for document-based macro projects. For normal code, this module is not used. • Forms — contains customized dialog boxes and user interfaces, plus the code to control them • Modules — contains code modules, for storing general code and macros • Class Modules — contains object-oriented Visual Basic class modules (which are not discussed in this documentation) In the Macro Editor, you cannot move a component from one folder to another within the same project. However, you can drag a component to another project to make a copy of it there. For details on creating macro projects, see the following procedures: • “To create a macro project” on page 45 • “To add a dialog box to a macro project” on page 46 • “To add a code module to a macro project” on page 46 • “To add a class module to a macro project” on page 47 To create a macro project • In the Macro Manager docker, do one of the following: • Click Visual Basic for Applications in the list, click New, and then click New macro project. • Right-click Visual Basic for Applications in the list, and then click New macro project. Project names must follow normal variable-naming conventions: They must begin with an alphabetic character, and they must not contain spaces nor special characters other than underscores ( _ ). You can also Load a macro project Do one of the following: •Click Visual Basic for Applications in the list, click Load, and then choose the project. •Right-click Visual Basic for Applications in the list, click Load macro project, and then choose the project. Rename a macro project Right-click the project in the list, and then click Rename. You can also rename a macro project from within the Macro Editor. Click the project in the Project Explorer, and then edit the (Name) value in the Properties window. Press Enter to commit your changes. Creating macros 45 You can also Right-click the project in the list, click Copy to, and then choose the target location for the copy. Copy a GMS-based macro project NOTE: You cannot copy a document-based macro project. Such projects are stored within a document and cannot be managed separately from that document. Unload a GMS-based macro project Right-click the macro project in the list, and then click Unload macro project. NOTE: You can close a document-based macro project only by closing the document in which it is stored. Some macro projects are locked and cannot be modified. To add a dialog box to a macro project 1 In the Project Explorer of the Macro Editor, right-click the project. 2 Click Insert ` UserForm. A form is added to the Forms folder for the project. Some macro projects are locked and cannot be modified. For more information, see “Providing dialog boxes for macros” on page 58. To add a code module to a macro project • Do one of the following: • In the Macro Manager docker, click the project in the list, click New, and then click New module. • In the Macro Manager docker, right-click the project in the list, and then click New module. • In the Project Explorer of the Macro Editor, right-click the project, and then click Insert ` Module. You can also Display or hide all code modules in the Macro Manager docker In the Macro Manager docker, click the Simple mode button . Edit a code module In the Macro Manager docker, do one of the following: •Click the module in the list, and then click the Edit button . •Right-click the module in the list, and then click Edit. The code module opens in the Macro Editor. In the Macro Manager docker, right-click the module in the list, and then click Rename. Rename a code module Creating macros 46 You can also In the Macro Manager docker, do one of the following: •Click the module in the list, and then click the Delete button . •Right-click the module in the list, and then click Delete. Delete a code module Some macro projects are locked and cannot be modified. To add a class module to a macro project 1 In the Project Explorer of the Macro Editor, right-click the project. 2 Click Insert ` Class Module. A new class module is added to the Class Modules folder for the project. Some macro projects are locked and cannot be modified. Detailed documentation on creating class modules is beyond the scope of this documentation. Writing macros You can manually code a macro by writing it in the Macro Editor or the VSTA Editor. (Alternatively, in Corel DESIGNER and CorelDRAW, you can create a VBA macro by recording it. For information, see “Recording macros” on page 48.) Macros that are developed in the Macro Editor or the VSTA Editor can take advantage of full programming control, including conditional execution, looping, and branching. In effect, you can write macros that are programs in their own right. In this documentation, all macro code is referred to as a macro. In some contexts, however, a macro is just those parts of the code that can be run by Corel DESIGNER, CorelDRAW, or Corel PHOTOPAINT. To write a macro, you must first add it to a code module for the desired macro project. You can edit, rename, or even delete macros. For details on writing macros, see the following procedures: • “To add a macro to a macro project” on page 47 • “To edit a VBA macro” on page 48 • “To delete a VBA macro” on page 48 To add a macro to a macro project • In the Macro Manager docker, do one of the following: • Click the desired container module in the macro project, click New, and then click New macro. • Right-click the desired container module in the macro project, and then click New macro. Creating macros 47 Some macro projects are locked and cannot be modified. To edit a VBA macro • In the Macro Manager docker, do one of the following: • Click the macro in the list, and then click the Edit button • Right-click the macro in the list, and then click Edit. The macro opens in the Macro Editor. . Some macro projects are locked and cannot be modified. For detailed information on manually coding macros, see “How is automation coding structured?” on page 14. To delete a VBA macro • In the Macro Manager docker, do one of the following: • Click the macro in the list, and then click the Delete button • Right-click the macro in the list, and then click Delete. . Some macro projects are locked and cannot be modified. Recording macros Corel DESIGNER and CorelDRAW offers a recording feature that lets you create a macro without needing to manually code it. For many simple and repetitive tasks, recorded macros are a quick, efficient solution: They store the sequence of keys that you press and the mouse actions that you perform within the application. You may prefer to create macros by recording them if you are not familiar with the object model for the application, or if you are not sure which objects and methods to use. In Corel PHOTO-PAINT, actions can be recorded as Corel SCRIPT scripts but not as VBA or VSTA macros. For information on recording scripts, see “Working with scripts” in the main Help file for Corel PHOTO-PAINT (corelpp.chm). If you want to store a recorded macro for future use, you can save it by using the Record Macro dialog box. Saving a recorded macro is particularly useful if you want to extend or customize its functionality by editing it in the Macro Editor. Creating macros 48 The Record Macro dialog box However, if you want to use a recorded macro during the current session only, you can record a temporary macro. For details on recording macros, see the following procedures: • “To record and save a macro” on page 49 • “To record a temporary macro” on page 50 To record and save a macro 1 Do one of the following: • Click Tools ` Macros ` Start recording, or click the Start recording button on the Macros toolbar, to store the macro in the default macro project for recordings. • In the Macro Manager docker, click the project in which to store the macro, and then click the Record button . The Record Macro dialog box appears. 2 In the Macro name box, type a name for the macro. Macro names can contain numerals, but they must begin with a letter. Macro names cannot contain spaces or non-alphanumeric characters other than underscores ( _ ). 3 Type a description of the macro in the Description box, and then click OK. 4 Perform the actions that you want to record. The application begins recording your actions. If you want to pause recording, do one of the following: • Click Tools ` Macros ` Pause recording. Repeat this step to resume recording. • Click the Pause recording button this step to resume recording. 5 on the Macros toolbar or in the Macro Manager docker. Repeat To stop recording, do one of the following: • Click Tools ` Macros ` Stop recording. Creating macros 49 • Click the Stop recording button • Press Ctrl + Shift + O. on the Macros toolbar or in the Macro Manager docker. You cannot record a macro if all available macro projects are locked.. Not all actions can be recorded — some because of their complexity (although many such actions can be manually coded in the Macro Editor). When an action cannot be recorded, a comment is placed in the macro code (“The recording of this command is not supported.”), but the recording process continues until you stop it. You can view any comments in the code by opening the macro in the Macro Editor. You can specify the default macro project for recordings by right-clicking the project in the Macro Manager docker, and then clicking Set as recording project. However, you cannot specify a locked macro project. You can cancel recording a macro, and discard any commands recorded thus far, by clicking Tools ` Macros ` Cancel recording. You can also Save the actions in the Undo list as a VBA macro Click Tools ` Undo, perform the actions that you want to record, and then click the Save list to a VBA macro button in the Undo docker. To record a temporary macro 1 Do one of the following: • Click Tools ` Macros ` Record temporary macro. • Press Ctrl + Shift + R. 2 Perform the actions that you want to record. The application begins recording your actions. If you want to pause recording, do one of the following: • Click Tools ` Macros ` Pause recording. Repeat this step to resume recording. • Click the Pause recording button this step to resume recording. 3 on the Macros toolbar or in the Macro Manager docker. Repeat To stop recording, do one of the following: • Click Tools ` Macros ` Stop recording. • Click the Stop recording button on the Macros toolbar or in the Macro Manager docker. • Press Ctrl + Shift + O. The macro is temporarily saved to the default recording project. When the current session is ended, the macro is deleted from that project. You cannot record a temporary macro if all available macro projects are locked. Not all actions can be recorded. Creating macros 50 You can specify the default recording project by right-clicking the project in the Macro Manager docker, and then clicking Set as recording project. (You cannot specify a locked macro project.) If you want, you can create multiple temporary recordings by assigning each one to its own macro project. You can cancel recording a macro, and discard any commands recorded thus far, by clicking Tools ` Macros ` Cancel recording. Running macros You can run saved macros in one of two ways: • from directly within Corel DESIGNER, CorelDRAW, or Corel PHOTO-PAINT • from within the Macro Editor The Run Macro dialog box You can also run any temporary macro recorded in Corel DESIGNER or CorelDRAW. For details on running macros, see the following procedures: • “To run a saved macro” on page 51 • “To run a temporary macro” on page 52 To run a saved macro • Do one of the following: • Click Tools ` Macros ` Run macro, or click the Run macro button on the Macros toolbar. From the Macros in list box, choose the project or file in which the macro is stored. From the Macro name list, choose the macro. Click Run. • In the Macro Manager docker, double-click the macro in the list. • In the Macro Manager docker, click the macro in the list, and then click the Run button . • In the Macro Manager docker, right-click the macro in the list, and then click Run. • In the Macro Editor, click anywhere in the subroutine that forms the macro, and then click Run ` Run macro. Creating macros 51 To run a temporary macro • Do one of the following: • Click Tools ` Macros ` Run temporary macro. • Press Ctrl + Shift + P. This option is enabled only after you record a temporary macro. If you have created multiple temporary macros, you must specify which macro project contains the one that you want to run. Right-click the project in the Macro Manager docker, and then click Set as recording project. Debugging macros To ensure that your macros run as expected, it’s important to debug them. The Macro Editor provides four windows for debugging VBA code. The Macro Editor also provides two strong debugging facilities that are common to language editors: setting breakpoints, and stepping through code. The Macro Editor also supports two advanced debugging techniques that are not discussed in this documentation: Making changes to the code while it is running, and watching and changing variables. Using the debugging windows The Macro Editor provides four windows for debugging VBA code: the Call Stack window, the Immediate window, the Locals window, and the Watches window. All of these windows provide important information about the state of functions and variables while an application is running. The Call Stack window is a modal dialog box that lists which function calls which function. In long, complicated applications, this information is useful for tracing the steps to a particular function being called. To visit a function listed in the window, select the function name and then click Show, or else close the window. To display the Call Stack window, click View ` Call Stack. The Call Stack window Creating macros 52 The Immediate window lets you type in and run arbitrary lines of code while a macro is paused. This functionality is useful for getting or setting the property of an object in the document, or for setting the value of a variable in the code. To run a piece of code, type it in the Immediate window, and then press Enter; the code is executed immediately. To display the Immediate window, click View ` Immediate window. The Immediate window The Locals window displays all variables and objects that exist within the current scope. The type and value for each variable are listed in the columns next to the name of the variable. Some variables and objects have several children, which can be displayed by clicking the button next to the parent. Many variables let you edit their value by clicking it. To display the Locals window, click View ` Locals window. The Locals window The Watches window is used to watch specific variables or object properties. This functionality is useful for watching just one or two values rather than searching for them among all the values in the Locals window. To display the Watches window, click View ` Watch window. Creating macros 53 The Watches window To add a value to the Watches window, do one of the following: • Select the variable or object and its property, and then drag the selection onto the Watches window. • Click the item, and then click Debug ` Quick watch. The Add Watch dialog appears. The Add Watch dialog box Select the item that you want to watch, select any conditions for this watch, and then click OK. If the condition becomes true, the application pauses to let you examine the code. Setting breakpoints A breakpoint is a marker in a line of code that causes execution to pause. To continue, you must either restart the execution or step through the subsequent lines of code. To set or clear a breakpoint, click the line, and then click Debug ` Toggle breakpoint. By default, the line is highlighted in dark red, and a red dot is placed in the margin. To restart the code after it pauses at a breakpoint, click Run ` Continue. To pause the execution of the code (immediately exiting from all functions and discarding all return values), click Run ` Reset. You can also “run to cursor” — that is, execute the code until it reaches the line that the cursor is on, and then pause at that line. To do this, click the line where you want execution to pause, and then click Debug ` Run to cursor. Creating macros 54 To clear all breakpoints, click Debug ` Clear all breakpoints. If the line with the breakpoint (or the cursor, when “running to cursor”) is not executed because it is in a conditional (if-then-else) block, the code does not stop at that line. Breakpoints are not saved. They are lost when you close the Macro Editor. Stepping through the code When execution pauses at a breakpoint, you can continue through the code one line at a time. This functionality, called “stepping through the code,” lets you do the following: • examine the values of individual variables after each line • determine how the code affects the values • determine how the values affect the code To step through the code, click Debug ` Step into. The execution advances to every line in all called functions and subroutines. To step through each line of the current function or subroutine but not through the lines of each called function or subroutine, click Debug ` Step over. The called functions and subroutines are executed, but not line-by-line. To execute the rest of the current function or subroutine but pause when the function or subroutine returns to the point where it was called, click Debug ` Step out. This technique is a quick way of returning to the point of entry of a function, to continue stepping through the code of the calling function. Creating macros 55 Making macros user-friendly An important part of many macro solutions is the user interface. A well-designed interface improves the ease-ofuse, power, and acceptance of a macro solution. Simple user interfaces can be created with toolbars, while more complex interfaces can be created with dialog boxes or dockers — and can even allow the user to interact with the mouse. However, for some macro solutions, a user interface alone is not enough. To make a macro solution as userfriendly as possible, you can provide documentation for it. This section contains the following topics: • “Providing toolbars for macros” on page 56 • “Providing dialog boxes for macros” on page 58 • “Providing user interaction for macros” on page 65 • “Providing documentation for macros” on page 68 Providing toolbars for macros A toolbar provides a basic interface that enhances the user’s experience with your macro solution. Toolbars are useful because their buttons are memorable even if small, and because those buttons can be set to display meaningful captions and helpful tooltips. Designing toolbars for macros When creating toolbars, you should plan carefully. Having multiple small toolbars containing a few related buttons is better than having one big toolbar containing all of the buttons for all of your macros. By breaking your buttons into small groups, it is much easier to deploy them with the projects to which they belong. For more information, see the following procedures: • “To create a macro toolbar” on page 57 • “To add buttons to a macro toolbar” on page 57 Associating images or icons with macros Macro commands can have an image or icon associated with them. This image or icon can be displayed or hidden on toolbars and menus, and it can be sized as small (16 × 16 pixels), medium (32 × 32 pixels), or large (48 × 48 pixels). For more information, see the following procedure: • “To associate an image or icon with a macro” on page 57 Corel DESIGNER Technical Suite X5 Macro Programming Guide 56 Setting captions and tooltips for macros Each macro can have both a caption and a tooltip. The caption is displayed whenever the menu command is used and can be displayed as part of a button, while the tooltip appears when the pointer hovers over the button or menu item. For more information, see the following procedures: • “To set a caption for a macro” on page 57 • “To set a tooltip for a macro” on page 58 To create a macro toolbar 1 Click Tools ` Options. 2 Click Workspace ` Customization ` Command bars. 3 Click New. 4 Type a name for the toolbar. 5 Enable the check box next to the name of the toolbar. To add buttons to a macro toolbar 1 Click Workspace ` Customization ` Commands. 2 Choose Macros from the Commands list box. The list displays the fully qualified names of all of the public, parameter-free subroutines from all of the installed project (GMS) files. 3 Drag a macro from the list to the toolbar. The macro appears on the toolbar with the default macro icon. To associate an image or icon with a macro 1 Click Workspace ` Customization ` Commands. 2 Choose Macros from the Commands list box. The list displays the fully qualified names of all of the public, parameter-free subroutines from all of the installed project (GMS) files. 3 Select a macro in the Command list. 4 Click the Appearance tab, and then do one of the following: • To apply a Windows bitmap (BMP) image to the macro, click Import, navigate to where the image is stored, and select it. The colors in the image are mapped to their closest available matches. • To create a customized icon for the macro, edit the pixels displayed in the Image area. To set a caption for a macro 1 Click Workspace ` Customization ` Commands. 2 Choose Macros from the Commands list box. The list displays the fully qualified names of all of the public, parameter-free subroutines from all of the installed project (GMS) files. Making macros user-friendly 57 3 Select a macro in the Command list. 4 Click the Appearance tab, and then type the caption in the Caption box. To specify a character in the caption as an accelerator that can be activated in combination with the Alt key, type an ampersand ( & ) in front of that character. This accelerator key applies only to menu commands, which display accelerator characters with an underscore ( _ ). To set a tooltip for a macro 1 Click Workspace ` Customization ` Commands. 2 Choose Macros from the Commands list box. The list displays the fully qualified names of all of the public, parameter-free subroutines from all of the installed project (GMS) files. 3 Select a macro in the Command list. 4 Click the General tab, and then type the tooltip in the Tooltip help box. Providing dialog boxes for macros A dialog box provides a user-friendly interface for more complex macro solutions. For best results, all dialog boxes must provide the following: • a meaningful title • an obvious function for cancelling or closing the dialog box • an easy-to-use layout • a Help button from which users can access how-to documentation • a tooltip (that is, a ControlTipText string) for every control There are two types dialog boxes: modal and modeless. Understanding modal dialog boxes A modal dialog box locks the application until the user acts on and then closes the dialog box. Most built-in dialog boxes for macro solutions are modal, and most modal dialog boxes provide the following buttons: • OK — performs an action and then closes the dialog box. This button is the default. • Cancel — closes the dialog box without performing an action. This button provides the same functionality as the Close button in the upper-right corner of a dialog box. In addition, some modal dialog boxes provide the following button: • Apply — performs an action that can be commited by clicking the OK button or cancelled by clicking the Cancel button Finally, most wizard-style dialog boxes provide the following buttons: • Previous — returns to the previous page. This button can be disabled on the first page of the dialog box. • Next — advances to the next page. This button can be replaced by a Finish button on the last page of the dialog box. • Finish — performs the action for the dialog box and then closes the dialog box Making macros user-friendly 58 Understanding modeless dialog boxes A modeless dialog box does not lock the application, so the user can leave the dialog box open and continue working in the application. In this way, modeless dialog boxes behave like dockers. Most modeless dialog boxes provide the following buttons: • Apply or Create — performs an action (and can, in fact, be specially labeled to describe that action). This button is typically the default. • Close –– closes the dialog box. This button is used after the action is applied. Choosing between modal and modeless dialog boxes Before you can create a dialog box for your macro solution, you must decide whether to make it modal or modeless by considering what you want the dialog box to achieve. For example, let’s say that you are creating a “one-shot” end-to-end solution such as a customized Print dialog box or Save dialog box. In this case, you would provide a modal dialog box because it is unlikely that the user would want to apply the specified settings repeatedly. On the other hand, let’s say that you are creating a solution for setting up an effect to apply to a selection of shapes. To let the user specify the desired settings and then apply them repeatedly, you would provide a modeless dialog box. After choosing which type of dialog box to provide, you are ready to set it up. For information, see “Setting up dialog boxes” on page 59. After setting up a dialog box, you are ready to code it. For information, see “Coding dialog boxes” on page 62. Setting up dialog boxes The Form Designer in the Macro Editor provides easy access to the tools for setting up a dialog box. You can access the Form Designer by creating a new, blank dialog box. In the Project Explorer, right-click the project to which you want to add a dialog box, and then click Insert ` UserForm. A blank form in the Form Designer Making macros user-friendly 59 The Form Designer provides two main features for designing dialog boxes: • the Form Designer toolbox • The UserForm toolbar The Form Designer also provides functions for naming and testing dialog boxes. Designing dialog boxes The Form Designer toolbox is the main utility for designing dialog boxes. It lets you add controls to a dialog box by dragging them from the toolbox. The Form Designer toolbox The Form Designer toolbox lets you add the following controls to a dialog box: Icon Control name Function Label Provides static text, such as instructions or captions TextBox Provides an area for typing text. For information on coding this control, see “Providing text boxes in dialog boxes” on page 62. ComboBox Provides a list from which a single item can be selected; optionally, also provides an area for typing text. For information on coding this control, see “Providing combination boxes and list boxes in dialog boxes” on page 63. ListBox Provides a list from which multiple items can be selected. For information on coding this control, see “Providing combination boxes and list boxes in dialog boxes” on page 63. CheckBox Provides a check box that can be enabled (by clicking to display a check mark), disabled (by clicking to remove the check mark), or grayed (that is, made unavailable) OptionButton Provides a “radio button” that is linked to other radio buttons with the same GroupName property, such that only one of the buttons can be enabled at a time Making macros user-friendly 60 Icon Control name Function ToggleButton Provides a button that can be toggled (to appear pressed or not pressed) Frame Groups items together so that they move with the frame CommandButton Provides a button that can be clicked to commit an assigned action. For information on coding this control, see “Providing buttons in dialog boxes” on page 63. TabStrip Provides separate views of related controls MultiPage Provides multiple pages of controls ScrollBar Provides immediate access to a range of values by scrolling SpinButton Enhances another control (such as a TextBox control) so that the value for that control can be set more quickly Image Provides an image. For information on coding this control, see “Providing images in dialog boxes” on page 65. The Form Designer toolbox also features a Pick tool on a dialog box. , which lets you select and move the controls To display a Help topic containing information about a selected dialog-box control in the Form Designer, press F1. The Form Designer also provides access to the UserForm toolbar, which you can use when designing a dialog box. For information on this toolbar, see “Using the Macro Editor toolbars” on page 36. Naming dialog boxes After you have finished designing your dialog box, you may want to change its title. Click the dialog box to select it, and then in the Properties window, change the Caption property. For clarity, you can give each dialog box a unique, descriptive name by using the Properties window. However, remember to follow the standard programming conventions for naming variables. Testing dialog boxes At any time, you can test your dialog box by pressing F5 to run it. After you finish setting up your dialog box, you can start coding it. For information, see “Coding dialog boxes” on page 62. Making macros user-friendly 61 Coding dialog boxes After setting up a dialog box, you can develop the VBA code for displaying it. You can also develop the code for providing its text boxes, combination boxes and list boxes, buttons, and images. Displaying dialog boxes The Show method for a dialog box lets you determine how the dialog box is displayed. For example, the following code uses the Show method to display the dialog box frmFooForm: frmFooForm.Show In addition, the Show method provides a Modal parameter, which lets you specify whether the dialog box is modal or modeless. A value of vbModal (or 1) for this parameter creates a modal dialog box, while a value of vbModeless (or 0) creates a modeless dialog box. The following VBA example creates a modeless dialog box: frmFooForm.Show vbModeless To open a dialog box from a macro that is available from within the application itself, you must create a public subroutine within a code module. However, a subroutine cannot be made available from within the application if the subroutine exists either within the code for a dialog box or within a class module. In addition, the subroutine cannot take any parameters. The following VBA example subroutine opens frmFooForm as a modeless dialog box: Public Sub showFooForm() frmFooForm.Show vbModeless End Sub When a dialog box loads, it triggers its own UserForm_Initialize event. From this event handler, you must initialize all the relevant controls on the dialog box. For more information, see “How are event handlers provided?” on page 23. Finally, you can also use the Show method to open additional dialog boxes from within the current one, as in the following VBA example: UserForm2.Show vbModal However, control is not returned to you until all open dialog boxes are unloaded. Providing text boxes in dialog boxes Text boxes (that is, TextBox controls) are the mainstay of user input. They are simple to use and quick to program, and they are suitable for a number of purposes. To set the text in a text box when initializing it, set the Text (default or implicit) property for the TextBox control, as in the following VBA example: txtWidth.Text = "3" txtHeight = "1" To get the value of a TextBox control, get its Text property in the Properties window, as in the following VBA example: Call SetSize(txtWidth.Text, txtHeight.Text) Making macros user-friendly 62 Providing combination boxes and list boxes in dialog boxes In a combination box (that is, a ComboBox control), the user can either choose an item from the list or type a value into the text box. You can prevent users from being able to type into a ComboBox control by setting its Style property (in the Properties window) to fmStyleDropDownList. In a list box (that is, a ListBox control), the user can choose one or more items (typically, from between three and ten items) from the list. To populate a list of any type, you must call the member function AddItem for the list. This function takes two parameters: the string or numerical value, and the position in the list. The position parameter is optional, so omitting it inserts the item at the last position in the list. For example, the following VBA code populates the list ComboBox1 with four items: ComboBox1.AddItem 1 ComboBox1.AddItem 2 ComboBox1.AddItem 3 ComboBox1.AddItem 0, 0 To test which item is selected when the OK button is clicked, test the ListIndex property for the list. To get the value of the caption for a selected combination box or list box, test the Text property for the item, as in the following VBA example: Dim retList As String retList = ComboBox1.Text Providing buttons in dialog boxes You can add a button to a dialog box by using the CommandButton control. Click the dialog box to add a default-sized button, or drag to create a custom-sized one. Click the caption to edit it, or select the button and edit its Caption property in the Properties window. You might also want to change the name of the button to something more descriptive, such as buttonOK or buttonCancel. Designing buttons in the Form Designer Making macros user-friendly 63 Most dialog boxes have an OK button and a Cancel button. However, no button functions until its dialog box has code for handling the click event for the button. (This is because dialog boxes in VBA and VSTA are eventdriven.) For an OK button, you can set its Default property to True so that the event handler for the button is called when the user presses Enter to activate the dialog box. That way, the click-event handler for the button performs the functionality of the dialog box and then unloads that dialog box. If the dialog box is used to set the size of the selected Corel DESIGNER or CorelDRAW shapes by setting their width and height, then the click-event handler for the OK button could resemble the following VBA code sample (which assumes you have already created two text boxes called txtWidth and txtHeight): Private Sub buttonOK_Click() Me.Hide Call SetSize(txtWidth.Text, txtHeight.Text) Unload Me End Sub Similarly, the size-setting Corel DESIGNER or CorelDRAW subroutine could resemble the following: Private Sub SetSize(width As String, height As String) ActiveDocument.Unit = cdrInch ActiveSelection.SetSize CDbl(width), CDbl(height) End Sub From inside the code module for the dialog box, the dialog-box object is implicit, so all the controls can be simply accessed by name. From other modules, the controls must be accessed through their full name (as in UserForm1.buttonOK). The Cancel button is the simplest control: it must dismiss the form without doing anything else. To add a cancel action to a Cancel button, double-click the button from within the Form Designer to display its code in the Code window. This creates a new subroutine called cmdCancel_Click: The Code window with code for a Cancel button Making macros user-friendly 64 The following VBA code, if applied to a Cancel button, dismisses the dialog box when the button is clicked: Private Sub cmdCancel_Click() Unload Me End Sub If you continue by setting the Cancel property for the dialog box to True, then when the user presses Escape, the cmdCancel_Click event is triggered and the provided code unloads the form. Providing images in dialog boxes The Image control is used to place graphics on a dialog box. The image (a bitmap) is contained in the Picture property, so you can either load an RGB image from a file (such as a GIF, JPEG, or Windows Bitmap BMP file) or paste one into the property. At run time, you can change the Picture property if you want to load a new image into the Image control. To change the Picture property, use the function LoadPicture and provide a path to the new image file, as in the following VBA example: Image1.Picture = LoadPicture("C:\Images\NewImage.gif") Providing user interaction for macros One way to make your macro solutions more user-friendly is to optimize them for user interaction, such as mouse input. A macro that captures mouse actions gives users real-time influence on the result of that macro. The Corel DESIGNER and CorelDRAW object models provide three main ways to receive mouse input from users, as explained in the following topics: • “Capturing mouse clicks” on page 65 • “Capturing mouse drags” on page 66 • “Capturing coordinates” on page 67 Capturing mouse clicks To get the position of a single mouse click, you can use the GetUserClick method of the Document class. This method pauses the macro until the specified period of time elapses, or until the user clicks in the document or presses Escape. Here is a VBA example that uses the Document.GetUserClick method: Dim doc As Document, retval As Long Dim x As Double, y As Double, shift As Long Set doc = ActiveDocument doc.Unit = cdrCentimeter retval = doc.GetUserClick(x, y, shift, 10, True, cdrCursorPick) The following parameters for the Document.GetUserClick method are coded into the preceding example: • The variable x returns the horizontal position of the mouse click. • The variable y returns the vertical position of the mouse click. Making macros user-friendly 65 • The parameter shift returns the combination of the Shift, Ctrl, and Alt keys that is held down by the user when clicking the mouse. The Shift, Ctrl, and Alt keys are assigned values of 1, 2, and 4 (respectively), the sum of which is the returned value. • The value 10 specifies the number of seconds for the user to click in the document. • The value True specifies that the SnapToObjects parameter is enabled. • The value cdrCursorPick specifies that the icon for the Pick tool is used for the cursor icon. (You cannot use a custom icon.) One of the following values is returned: • 0 — The user successfully completes the click. • 1 — The user cancels by pressing Escape. • 2 — The operation times out. The returned coordinates are relative to the origin of the page and, unless explicity specified, are in document units. To get the shapes under the returned click point, you can use the method SelectShapesAtPoint (which is a member of Page), as in the following VBA example: doc.ActivePage.SelectShapesAtPoint x, y, True A value of True selects unfilled objects, while False does not select unfilled objects. Capturing mouse drags To get the position of a mouse drag (or an area or rectangle), you can use the GetUserArea method of the Document class. This method pauses the macro until the specified period of time elapses, or until the user clicks, drags, and releases in the document or presses Escape. Here is a VBA example that uses the Document.GetUserArea method: Dim doc As Document, retval As Long, shift As Long Dim x1 As Double, y1 As Double, x2 As Double, y2 As Double Set doc = ActiveDocument doc.Unit = cdrCentimeter retval = doc.GetUserArea(x1, y1, x2, y2, shift, 10, True, cdrCursorExtPick) ActivePage.SelectShapesFromRectangle x1, y1, x2, y2, False The following parameters for the Document.GetUserArea method are coded into the preceding example: • The variables x1 and y1 return the horizontal and vertical positions (respectively) of the upper-left corner of the area. • The variables x2 and y2 return the horizontal and vertical positions (respectively) of the lower-right corner of the area. • The parameter shift returns the combination of the Shift, Ctrl, and Alt keys that is held down by the user when dragging the mouse. The Shift, Ctrl, and Alt keys are assigned values of 1, 2, and 4 (respectively), the sum of which is the returned value. • The value 10 specifies the number of seconds for the user to click in the document. • The value True specifies that the SnapToObjects parameter is enabled. Making macros user-friendly 66 • The value cdrCursorExtPick specifies the icon to use for the cursor. In the preceding example, the code ends by selecting the shapes that lie completely within the area by using the Page.SelectShapesFromRectangle method. One of the following values is returned: • 0 — The user successfully completes the selection. • 1 — The user cancels by pressing Escape. • 2 — The operation times out. This method returns two points that are interpreted as the corners of a rectangle. However, the two points can also be used as the start point and end point of a mouse drag. The returned coordinates are relative to the origin of the page and, unless explicity specified, are in document units. Capturing coordinates When capturing mouse actions, or when developing a complex macro solution, you may want to convert between screen coordinates and document coordinates. This conversion is done with the methods ScreenToDocument and DocumentToScreen of the Window class. The following VBA example converts a set of screen coordinates into a point in the document that is visible in the active window: Dim docX As Double, docY As Double ActiveDocument.Unit = cdrMillimeter ActiveWindow.ScreenToDocument 440, 500, docX, docY The following VBA example returns the screen coordinates of a point in the document as it appears on the screen: Dim screenX As Long, screenY As Long ActiveDocument.Unit = cdrMillimeter ActiveWindow.DocumentToScreen 40, 60, screenX, screenY In both examples, the converted coordinates are returned in the last two parameters. Screen coordinates start from the upper-left corner of the screen, so positive y-values are down the screen, whereas negative y-values are up the screen. You can test whether a set of coordinates (that is, a point) is inside, outside, or on the outline of a curve by using the Shape.IsOnShape method. For a set of document coordinates, this method returns one of the following: • cdrInsideShape — if the coordinate is inside the shape • cdrOutsideShape — if the coordinate is outside the shape • cdrOnMarginOfShape — if the coordinate is on or near the outline of the shape Making macros user-friendly 67 For example, the following VBA code tests where the point (4, 6) is in relation to the active shape: Dim onShape As Long ActiveDocument.Unit = cdrInch onShape = ActiveShape.IsOnShape(4, 6) Providing documentation for macros To make a macro as user-friendly as possible, you can provide documentation for it. One solution is to create a Readme file or a printed manual. Another solution is to incorporate the documentation directly into the user interface for the macro, but this method uses up valuable on-screen “real estate.” Yet another solution is to create an online Help system, but this method requires special tools and a fair amount of additional work. Perhaps the simplest way to provide macro documentation is in the form of a plain-text file. In fact, upon installation, a macro project can create a registry value that points to the location of this file. In VBA, the following function can be used to open a plain-text file (where the parameter file provides the full path to the file, such as C:\ReadMe.txt): Public Sub launchNotepad(file As String) Shell "Notepad.exe" & " " & file, vbNormalFocus End Sub A much more powerful solution is to provide documentation in HTML format. HTML provides numerous benefits over plain-text, including support for graphics and for hypertext links (such as to specific locations in the document — for example, index.html#middle). In VBA, the following function can be used to open an HTML file (where the parameter url provides the full path to the file — such as C:\ReadMe.txt — or a URL for the file): ' Put this Declare statement before all Subs and Functions! Declare Function ShellExecute Lib "shell32.dll" _ Alias "ShellExecuteA" (ByVal hwnd As Long, _ ByVal lpOperation As String, ByVal lpFile As String, _ ByVal lpParameters As String, ByVal lpDirectory As String, _ ByVal nShowCmd As Long) As Long Public Sub launchBrowser(url As String) ShellExecute 0, vbNullString, url, vbNullString, vbNullString, 5 End Sub Making macros user-friendly 68 Organizing and deploying macros When you’ve finished developing your macro solution, you can make it available to other users. This section contains the following topics: • “Organizing macros” on page 69 • “Deploying macros” on page 69 Organizing macros To make your macro solutions easy to deploy, you can organize them. Here are some tips: • To sort your macros, use a separate code module for each macro, and then group related macros into a single GMS file. • To help users find the entry point to a macro, place all public subroutines into a single code module so that the macro can be called from within the application. Deploying macros You can deploy macro solutions to users for installation. You can deploy GMS files or workspaces, or both. Deploying GMS files Every document has an intrinsic GMS file. For this reason, you can explicitly distribute a macro as part of a document because when that document is opened, the user has immediate access to its macros. This deployment technique lets you, for example, set up a macro to track how much time the user has spent editing a document. Alternatively, you can distribute the code module that contains the macro. However, this deployment method requires users to manually integrate the code module into an existing project file. The simplest and most reliable way to deploy a macro project is to use its GMS file. To begin, you must export the GMS file from your computer. Then, each user must import the GMS file by using the Macro Manager docker. For more information, see the following procedures: • “To export a GMS file” on page 70 • “To import a GMS file” on page 70 Deploying workspaces Some macro solutions include a customized workspace that contains relevant toolbars, menus, and shortcut keys. You can deploy the features of a customized workspace to users by creating a Corel workspace (XSLT) file. Corel DESIGNER Technical Suite X5 Macro Programming Guide 69 You can export a subset of workspace features — such as individual menus, individual toolbars, or complete sets of shortcut keys — if you want users to install only those features, or you can export the entire workspace if you prefer. For more information, see “To export workspace features” on page 70. Users can install customized workspace features by importing the XSLT files that you provide. For more information, see “To import workspace features” on page 71. In Corel DESIGNER and CorelDRAW, users can also import workspace features by using the Application.ImportWorkspace method. To export a GMS file • Locate the GMS file on your computer, and make it available to your users. User-created macro projects are typically stored at the following locations: • on Windows 7 and Windows Vista: X:\Users\ \AppData\Roaming\Corel\ \ (where X: is the drive where the software is installed, is the name of the user, is the folder where the software is installed, and is the application subfolder) • on Windows XP: X:\Documents and Settings\ \Application Data\Corel\ \ (where X: is the drive where the software is installed, is the name of the user, is the folder where the software is installed, and is the application subfolder) To import a GMS file 1 Save the GMS file to your computer. User-created macro projects are typically stored at the following locations: • on Windows 7 and Windows Vista: X:\Users\ \AppData\Roaming\Corel\ \ (where X: is the drive where the software is installed, is the name of the user, is the folder where the software is installed, and is the application subfolder) • on Windows XP: X:\Documents and Settings\ \Application Data\Corel\ \ (where X: is the drive where the software is installed, is the name of the user, is the folder where the software is installed, and is the application subfolder) 2 In the Macro Manager docker, do one of the following: • Click Visual Basic for Applications in the list, click Load, and then choose the project. • Right-click Visual Basic for Applications in the list, and then click Load macro project. To export workspace features 1 Right-click the menu bar, and click Customize ` Workspace ` Export Workspaces. 2 In the list, enable the check boxes next to the workspace features that you want to export: • Dockers — includes the sizes and positions of dockers • Menus — lets you choose which menus to include Organizing and deploying macros 70 • Shortcut Keys — includes all available shortcut keys • Status Bar — includes the status bar • Toolbars — lets you choose which toolbars to include Enable all check boxes if you want to export the entire workspace. 3 Click Save. 4 In the File name box, type a filename. The specified workspace features are saved to a single Corel workspace (XSLT) file with the specified filename. If you want, you can export each workspace feature to a separate file. Simply export one item at a time to create a series of XSLT files. When you export shortcut keys, you export all shortcut keys. If you want to distribute only a few keys, create a new workspace, remove all shortcut keys from it, and then add only the desired keys. To import workspace features 1 Right-click the toolbar, and click Customize ` Workspace ` Import Workspaces. 2 Click Browse. 3 Select the desired Corel workspace (XSLT) file, and then click Next. 4 In the list, enable the check boxes next to the workspace features that you want to import: • Dockers — includes the sizes and positions of dockers • Menus — lets you choose which menus to include • Shortcut Keys — includes all available shortcut keys • Status Bar — includes the status bar • Toolbars — lets you choose which toolbars to include Enable all check boxes if you want to import the entire workspace. 5 Click Next. 6 Choose a destination for the workspace features by doing one of the following: • Enable the Current workspace option to import the specified workspace features into the current workspace, and then click Next. • Enable the New workspace option to import the specified workspace features into a new workspace. Click Next, and provide details about the workspace. Click Next. 7 Confirm the details of the import, and then click Finish. The specified workspace features are imported into the specified workspace. If the name of an incoming toolbar is the same as an existing toolbar, the incoming toolbar is renamed. If an imported command calls an uninstalled macro, it does not function. Organizing and deploying macros 71 Understanding the Corel DESIGNER and CorelDRAW object models In Corel DESIGNER and CorelDRAW, the Application object is the root of all other objects and is used if no other root object is specified. You can use the application’s Application object to reference the application’s object model from an out-of-process controller. Here’s a Visual Basic example for Corel DESIGNER: Dim des As CorelDESIGNER.Application Set des = CreateObject("CorelDESIGNER.Application") Here’s a Visual Basic example for CorelDRAW: Dim cdr As CorelDRAW.Application Set cdr = CreateObject("CorelDRAW.Application") If desired, you can avoid using the CreateObject keyword in the preceding example by importing the target type library and using the data types directly. The Application object contains a Documents collection of all open Document objects (or “documents”) in the application. When a Corel DESIGNER or CorelDRAW document is created or opened, a corresponding Document object is added to the Documents collection for the Application object. Each Document object contains a Pages collection of all the Page objects (or “pages”) in that document. Each Page object contains a Layers collection of all the Layer objects (or “layers”) on that page. Finally, each Layer object contains a Shapes collection of all the Shape objects (or “shapes”) on that layer. In addition, the object model contains a set of filter objects, which provide support for files from other technicalgraphics applications. Import filters are governed by the Layer class, while export filters are governed by the Document class. Documents, pages, layers, shapes, and filters are among the most important objects in the Corel DESIGNER and CorelDRAW object models. Understanding these objects — and their relationships to one another — is the key to understanding the Corel DESIGNER and CorelDRAW object models. This section contains the following topics: • “Working with documents” on page 73 • “Working with pages” on page 93 • “Working with layers” on page 99 • “Working with shapes” on page 103 • “Working with import filters and export filters” on page 143 All code examples in this section are written in VBA. Corel DESIGNER Technical Suite X5 Macro Programming Guide 72 For a visual representation of the application’s entire object model, please see the object-model diagram at X:\Program Files\Corel\ \Data (where X: is the drive and is the folder where the software is installed): • for Corel DESIGNER: Corel DESIGNER Object Model Diagram.pdf • for CorelDRAW: CorelDRAW Object Model Diagram.pdf Working with documents Each open document, or Document object, is a member of the Application.Documents collection. The documents in that collection appear in the order in which they were created or opened. Corel DESIGNER and CorelDRAW provide a number of properties, methods, and events for working with documents, the most useful of which are listed in the following table. Class Member Description ActiveView OriginX property and OriginY property Combine to specify the origin of the active view SetViewPoint method Specifies the origin of the active view ActiveView For more information, see “Panning” on page 86. For more information, see “Panning” on page 86. ActiveView Zoom property Specifies the zoom factor of the active view For more information, see “Zooming” on page 85. AddInHook New event Is triggered when a document is created For more information, see “Creating documents” on page 82.

Imported files are placed on document layers, so information on importing files is provided in the section on working with layers (see “Importing files into layers” on page 102) rather than in this section on working with documents. Creating documents The Application object has two methods for creating documents: CreateDocument and CreateDocumentFromTemplate. The Application.CreateDocument method creates an empty document based on the default page size, orientation, and styles: Application.CreateDocument() As Document The Application.CreateDocumentFromTemplate method creates an untitled document from a specified template (CDT) file: Application.CreateDocumentFromTemplate(Template As String, _ [IncludeGraphics As Boolean = True])As Document Both of these functions return a reference to the new document, so they are typically used in the following manner: Dim newDoc as Document Set newDoc = CreateDocument The new document becomes active immediately and can be referenced by using the Application.ActiveDocument property. For more information on this property, see “Activating documents” on page 83. If you want, you can use event handlers to respond to events that are triggered by creating a document: • AddinHook.New • Application.DocumentNew • GlobalMacroStorage.DocumentNew Opening documents To open a document, you can use the Application.OpenDocument method. VBA example for Corel DESIGNER: Dim doc As Document Set doc = OpenDocument("C:\graphic1.des") VBA example for CorelDRAW: Dim doc As Document Set doc = OpenDocument("C:\graphic1.cdr") Understanding the Corel DESIGNER and CorelDRAW object models 82 If you want, you can use event handlers to respond to events that are triggered by opening a document: • Application.DocumentOpen • Document.Open • GlobalMacroStorage.DocumentOpen Activating documents Each open document is a member of the Application.Documents collection. The documents in that collection appear in the order in which they were created or opened. To reflect the actual stacking order of the documents, you must use the Application.Windows collection. The Application.ActiveDocument property provides direct access to the active document — that is, the document that is in front of all the other documents in the application window. ActiveDocument is an object of type Document and, therefore, has the same members — properties, methods, and objects — as the Document class. If no documents are open, ActiveDocument returns nothing. You can check for open documents by using the following VBA code: If Documents.Count = 0 Then MsgBox "There aren't any open documents.", vbOK, "No Docs" Exit Sub End If The Document.Activate method activates a document so that it can be referenced by ActiveDocument. The following VBA code activates the third open document (if three or more documents are open): Documents(3).Activate Using the Document.Activate method on the Application.ActiveDocument property has no effect. If you want, you can specify which open document to activate by referencing the one of the following properties: • Document.FilePath — checks only the file path (for example, C:\MyFiles) • Document.FileName — checks only the filename (for example, Test.cdr) • Document.FullFileName — checks both the file path and the filename (for example, C:\MyFiles\Test.cdr) You can check the filename of each open document by using the following VBA code: Public Function findDocument(filename As String) As Document Dim doc As Document For Each doc In Documents If doc.FileName = filename Then Exit For Set doc = Nothing Next doc Set findDocument = doc End Function Understanding the Corel DESIGNER and CorelDRAW object models 83 You can then activate the returned document by using the Document.Activate method. Setting document properties You can specify the reference point, unit of measurement, and drawing scale for a document by using the corresponding properties of the Document class. The Document.ReferencePoint property specifies the reference point for a document. This point is referenced when positioning the objects in that document. The Document.Unit property specifies the unit of measurement for a document. This unit is used to position and size the objects in that document. The Document.WorldScale property specifies the drawing scale for a document. The drawing scale lets you make the distances in a drawing proportionate to real-world distances; for example, you can specify that 1 inch in the drawing corresponds to 1 meter in the physical world. These properties affect all elements in your document, such as the objects that you draw. For optimal results, choose the settings that best fit your macro solution. Displaying documents You can simultaneously display multiple windows for a single document. For example, a large document can be displayed with one window zoomed in to the upper-right corner of the document and another zoomed in to the lower-right corner. Although the individual windows can be zoomed and panned independently, turning the page in one window affects all windows. By using the View Manager, you can create views that have individual display settings. Choosing a saved view displays the page according to the settings for that view. In VBA, the Window object provides access to the windows that contain each View object for (or view of) a given document. The Window object represents a frame, while the View object displays the document inside that frame. Besides letting you work with windows and views, the application lets you display documents by zooming and panning. Working with windows Each Document object has a Windows collection for displaying that document. To switch between windows, use the Window.Activate method: ActiveDocument.Windows(2).Activate The Document.ActiveWindow property provides direct access to the active window — that is, the document window that is in front of all other document windows. The next window and previous window for the active document are referenced in the Window.Next and Window.Previous properties: ActiveWindow.Next.Activate Understanding the Corel DESIGNER and CorelDRAW object models 84 To create a new window, use the Window.NewWindow method: ActiveWindow.NewWindow To close a window (and the document, if it has only one open window), use the Window.Close method: ActiveWindow.Close If you want, you can use event handlers to respond to events that are triggered by activating a window: • Application.WindowActivate • GlobalMacroStorage.WindowActivate You can also use event handlers to respond to events that are triggered by deactivating a window: • Application.WindowDeactivate • GlobalMacroStorage.WindowDeactivate Working with views The Window.ActiveView property and the Document.Views property both represent document views. Each Window object has one ActiveView object, which represents the current view of the document; saving the display settings for an ActiveView object creates a view. In contrast, each Document object has a collection of View objects in its Views property; choosing a View object activates the corresponding saved view, which contains the display settings for the corresponding ActiveView object. The only way to access an ActiveView object is from the Window.ActiveView property. You can create a View object and add it to a Document.Views collection. The following VBA code adds the current ActiveView settings to the Views collection: ActiveDocument.Views.AddActiveView "New View" You can also create a view with specific settings by using the Document.CreateView method. The following VBA code creates a new View object that accesses the position (3, 4) in inches, uses a zoom factor of 95%, and displays page 6: ActiveDocument.Unit = cdrInch ActiveDocument.CreateView "New View 2", 3, 4, 95, 6 To apply a saved view to the active window, call the View.Activate method: ActiveDocument.Views("New View").Activate Zooming To zoom an ActiveView object by a set amount, set the ActiveView.Zoom property by specifying a double value in percent. For example, the following VBA code sets the zoom factor to 200%: ActiveWindow.ActiveView.Zoom = 200.0 Understanding the Corel DESIGNER and CorelDRAW object models 85 You can also zoom by using the following methods of the ActiveView class: • SetActualSize • ToFitAllObjects • ToFitArea • ToFitPage • ToFitPageHeight • ToFitPageWidth • ToFitSelection • ToFitShape • ToFitShapeRange Panning To pan an ActiveView object, you can move its origin by modifying the ActiveView.OriginX and ActiveView.OriginY properties. The following VBA code pans the document 5 inches to the left and 3 inches up: Dim av As ActiveView ActiveDocument.Unit = cdrInch Set av = ActiveWindow.ActiveView av.OriginX = av.OriginX - 5 av.OriginY = av.OriginY + 3 Alternatively, you can use the ActiveView.SetViewPoint method: Dim av As ActiveView ActiveDocument.Unit = cdrInch Set av = ActiveWindow.ActiveView av.SetViewPoint av.OriginX - 5, av.OriginY + 3 Modifying documents You can modify a document regardless of whether it is active. Modifying an inactive document does not activate that document. To activate a document, you must use its Activate method (see “Activating documents” on page 83). The following VBA code adds a layer named “fooLayer” to the third open document: Dim doc As Document Set doc = Documents(3) doc.ActivePage.CreateLayer "fooLayer" Understanding the Corel DESIGNER and CorelDRAW object models 86 The following VBA code uses the findDocument() function to add a layer named “fooLayer” to the inactive document named barDoc.cdr: Dim doc As Document Set doc = findDocument("barDoc.cdr") If Not doc Is Nothing Then doc.ActivePage.CreateLayer "fooLayer" Creating command groups for documents Two very useful methods of the Document class combine to create a “command group,” which can reduce a series of programmed, document-related actions to a single, undoable step. These methods — BeginCommandGroup and EndCommandGroup — are demonstrated in the following VBA example: Dim sh As Shape ActiveDocument.BeginCommandGroup "CreateCurveEllipse" Set sh = ActiveLayer.CreateEllipse(0, 1, 1, 0) sh.ConvertToCurves ActiveDocument.EndCommandGroup The preceding code sets the Undo string in the Edit menu as Undo CreateCurveEllipse. Clicking this command undoes not only the ConvertToCurves operation but also the CreateEllipse operation. A command group can contain many hundreds of commands, if required. Creating command groups can make your macros appear to be fully integrated into the application. Saving documents Two methods can be used for saving documents: Document.SaveAs and Document.Save. The Document.SaveAs method saves a document by using the specified file path and filename. You can use this method to save a previously unsaved document or to save an existing document to a different file. The Document.SaveAs method provides an optional parameter that lets you access the StructSaveAsOptions class to specify additional settings. The Document.Save method saves over an existing document file — that is, by using the existing file path and filename for the document. If you want, you can use event handlers to respond to events that are triggered by opening the Save dialog box: • Application.DocumentBeforeSave • Document.BeforeSave • GlobalMacroStorage.DocumentBeforeSave You can also use event handlers to respond to events that are triggered by saving a document and closing the Save dialog box: • Application.DocumentAfterSave • Document.AfterSave • GlobalMacroStorage.DocumentAfterSave Understanding the Corel DESIGNER and CorelDRAW object models 87 Finally, you can also use event handlers to respond to events that are triggered when the user responds to a request to save a document: • Application.QueryDocumentSave • Document.QuerySave • GlobalMacroStorage.QueryDocumentSave Exporting files from documents Files of all supported formats can be exported. Files are exported at the Document level because the range of exported objects can extend over multiple layers and multiple pages. However, files are imported at the Layer level because each imported object is assigned to a specified layer on a specified page (see “Importing files into layers” on page 102). The Document class has three file-export methods — Export, ExportEx, and ExportBitmap — all of which can export to the bitmap and vector formats. The wide selection of supported file formats is due to the vast number of filters that are available to the application. Each filter lets you work with the files from another graphics application. To learn more about working with these filters, see “Working with import filters and export filters” on page 143. If you want, you can use event handlers to respond to events that are triggered by opening the Export dialog box: • Application.DocumentBeforeExport • Document.BeforeExport • GlobalMacroStorage.DocumentBeforeExport You can also use event handlers to respond to events that are triggered by exporting a document and closing the Export dialog box: • Application.DocumentAfterExport • Document.AfterExport • GlobalMacroStorage.DocumentAfterExport Finally, you can also use event handlers to respond to events that are triggered when the user responds to a request to export a document: • Application.QueryDocumentExport • Document.QueryExport • GlobalMacroStorage.QueryDocumentExport Understanding the Document.Export method To export a page, you require only the Document.Export method, a filename, and a filter type. The following VBA code exports the current page to a TIFF bitmap file: ActiveDocument.Export "C:\ThisPage.eps", cdrTIFF Understanding the Corel DESIGNER and CorelDRAW object models 88 However, the preceding code gives little control over the output of the image. More control is obtained by including a StructExportOptions object, as in the following VBA code: Dim expOpts As New StructExportOptions expOpts.ImageType = cdrCMYKColorImage expOpts.AntiAliasingType = cdrNormalAntiAliasing expOpts.ResolutionX = 72 expOpts.ResolutionY = 72 expOpts.SizeX = 210 expOpts.SizeY = 297 ActiveDocument.Export "C:\ThisPage.eps", cdrTIFF, cdrCurrentPage, expOpts A StructPaletteOptions object can also be included in the function call for palette-based image formats, if you want to provide the settings for automatically generating the palette. Understanding the Document.ExportEx method The Document.ExportEx method is the same as the Document.Export method, except that ExportEx can retreive the dialog-box settings for a filter and apply those settings to the export: Dim eFilt As ExportFilter Set eFilt = ActiveDocument.ExportEx("C:\ThisPage.eps", cdrEPS) If eFilt.HasDialog = True Then If eFilt.ShowDialog = True Then eFilt.Finish End If Else eFilt.Finish End If Understanding the Document.ExportBitmap method The Document.ExportBitmap method is similar to the Document.ExportEx method in that it returns an ExportFilter object that can be used to display the Export dialog box. However, the ExportBitmap method simplifies the coding by taking the individual members of the StructExportOptions object as parameters: Dim eFilt As ExportFilter Set eFilt = ActiveDocument.ExportBitmap("C:\Selection.eps", _ cdrTIFF, cdrSelection, cdrCMYKColorImage, _ 210, 297, 72, 72, cdrNormalAntiAliasing, _ False, True, False, cdrCompressionLZW) eFilt.Finish Understanding the Corel DESIGNER and CorelDRAW object models 89 Publishing documents to PDF Publishing documents to PDF is a two-step process. The first step is to specify the PDF settings (although this step can be skipped by specifying those settings from the application or by using the default settings). The second step is to export the file. To specify the PDF settings, you can use the Document.PDFSettings property. This property is an object of type PDFVBASettings and contains properties for all PDF settings that can be set in the Publish To PDF dialog box. The following VBA code for CorelDRAW exports pages 2, 3, and 5 to a PDF file named MyPDF.pdf: Dim doc As Document Set doc = ActiveDocument With doc.PDFSettings .Author = "Corel Corporation" .Bookmarks = True .ColorMode = pdfRGB .ComplexFillsAsBitmaps = False .CompressText = True .DownsampleGray = True .EmbedBaseFonts = True .EmbedFonts = True .Hyperlinks = True .Keywords = "Test, Example, Corel, CorelDRAW, PublishToPDF" .Linearize = True .PageRange = "2-3, 5" .pdfVersion = pdfVersion13 .PublishRange = pdfPageRange .TrueTypeToType1 = True End With doc.PublishToPDF "C:\MyPDF.pdf" The following VBA example gives more control to the user by displaying the Publish to PDF Settings dialog box: Dim doc As Document Set doc = ActiveDocument If doc.PDFSettings.ShowDialog = True Then doc.PublishToPDF "C:\MyPDF.pdf" End If Profiles for PDF settings can be saved and loaded by using the PDFVBASettings.Save method and PDFVBASettings.Load method (respectively). Understanding the Corel DESIGNER and CorelDRAW object models 90 Printing documents Using VBA to print documents is straightforward: almost all settings that are available in the Print dialog box are available to the Document.PrintSettings property. When these properties are set, printing the document is simply a matter of calling the Document.PrintOut method. For example, the following VBA code prints three copies of pages 1, 3, and 4 to a level-3 PostScript® printer: With ActiveDocument.PrintSettings .Copies = 3 .PrintRange = prnPageRange .PageRange = "1, 3-4" .Options.PrintJobInfo = True With .PostScript .DownloadType1 = True .Level = prnPSLevel3 End With End With ActiveDocument.PrintOut Each page in the Print dialog box has a corresponding object-model class that contains all settings for that page. The following table lists these classes. Page in Print dialog box Class in object model General PrintSettings Layout PrintSettings and PrintLayout Separations PrintSeparations and PrintTrapping Prepress PrintPrepress PostScript PrintPostScript Misc PrintOptions You cannot set layout options in VBA. However, if necessary, you can open the Print dialog box by using the PrintSettings.ShowDialog method. You can print only the selected objects in a document by setting the PrintSettings.PrintRange property to prnSelection. You can use a specific printer in the Application.Printers collection by specifying it in the PrintSettings.Printer property. You can save a printing profile by using the PrintSettings.Save method. You can access a saved printing profile by using the PrintSettings.Load method, but be sure to specify the full path to the profile. Understanding the Corel DESIGNER and CorelDRAW object models 91 You can reset the print settings by using the PrintSettings.Reset method. If you want, you can use event handlers to respond to events that are triggered by opening the Print dialog box: • Application.DocumentBeforePrint • Document.BeforePrint • GlobalMacroStorage.DocumentBeforePrint You can also use event handlers to respond to events that are triggered by printing a document and closing the Print dialog box: • Application.DocumentAfterPrint • Document.AfterPrint • GlobalMacroStorage.DocumentAfterPrint Finally, you can also use event handlers to respond to events that are triggered when the user responds to a request to print a document: • Application.QueryDocumentPrint • Document.QueryPrint • GlobalMacroStorage.QueryDocumentPrint Closing documents You can close a document by calling the Document.Close method. The following VBA code closes the active document and activates the document behind it: ActiveDocument.Close If the code closes a document that is not active, the document referenced by the Application.ActiveDocument property does not change. You must explicitly test the Dirty property for a document and take appropriate action if that document has been modified. You can also close a document by using the Close method of the Document object itself (as in doc.Close). If you want, you can use event handlers to respond to events that are triggered by closing a document: • Application.DocumentClose • Document.Close • GlobalMacroStorage.DocumentClose You can also use event handlers to respond to events that are triggered when the user responds to a request to close a document: • Application.QueryDocumentClose • Document.QueryClose • GlobalMacroStorage.QueryDocumentClose Understanding the Corel DESIGNER and CorelDRAW object models 92 Working with pages Each page, or Page object, is a member of the Document.Pages collection for the document in which it appears. The pages in a Document.Pages collection appear in the order in which they appear in that document — for example, the fifth page in the active document is ActiveDocument.Pages.Item(5). If pages are added, reordered, or deleted, the affected Pages collection is immediately updated to reflect the new page order of that document. Corel DESIGNER and CorelDRAW provide a number of properties, methods, and events for working with pages, the most useful of which are listed in the following table. Class Member Description Application ActivePage property Provides direct access to the active page of the active document For more information, see “Activating pages” on page 96.

For detailed information on any property, method, or event, see “Object Model Reference” section in the Macros Help file for the application. For more information on page-related activities, see the following topics: • “Creating pages” on page 95 • “Activating pages” on page 96 • “Reordering pages” on page 96 • “Sizing pages” on page 97 • “Modifying pages” on page 98 • “Deleting pages” on page 98 Creating pages The methods for creating pages belong to the Document class. Both the Document.AddPages method and the Document.AddPagesEx method add the specified number of pages to the end of a document. The difference between these methods is that AddPages uses the default page size, while AddPagesEx uses a specified size. Similarly, both the Document.InsertPages method and the Document.InsertPagesEx method insert the specified number of pages at the specified location in a document. The difference between these methods is that InsertPages uses the default page size, while InsertPagesEx uses a specified size. As an example, the following VBA code uses the AddPages method to add three default-sized pages to the end of the document: Public Function AddSomeSimplePages() as Page Set AddSomeSimplePages = ActiveDocument.AddPages(3) End Function The following VBA example uses the AddPagesEx method to add to the end of the document three pages that are 8.5 inches wide by 11 inches high: Public Function AddSomeSpecifiedPages() as Page Dim doc as Document Set doc = ActiveDocument doc.Unit = cdrInch Set AddSomeSpecifiedPages = doc.AddPagesEx(3, 8.5, 11) End Function Understanding the Corel DESIGNER and CorelDRAW object models 95 The preceding examples return the first page that was added; all other added pages follow this page. You can therefore reference any of the added pages by incrementing the Index property of the returned page: Dim firstNewPage As Page, secondNewPage As Page Set firstNewPage = AddSomeSimplePages Set secondNewPage = ActiveDocument.Pages(firstNewPage.Index + 1) If you want, you can use event handlers to respond to events that are triggered by creating a page: • Document.PageCreate Activating pages Each page is a member of the Document.Pages collection for the document in which it appears. The pages in a Document.Pages collection appear in the order in which they appear in that document — for example, the fifth page in the active document is ActiveDocument.Pages.Item(5). If pages are added, reordered, or deleted, the affected Pages collection is immediately updated to reflect the new page order of that document. You can access the active page of the active document by using the Application.ActivePage property (or ActiveDocument.ActivePage, or simply ActivePage). A reference to the active page in the active document, of type Page, is returned. Dim pg As Page Set pg = ActivePage You can access the active page of a document, regardless of whether that document is active, by using ActivePage property for that document: Public Function getDocsActivePage(doc As Document) As Page Set getDocsActivePage = doc.ActivePage End Function You can switch pages by finding the desired page and then invoking its Activate method. The following VBA code activates page 3 in a document: ActiveDocument.Pages(3).Activate If you want, you can use event handlers to respond to events that are triggered by activating a page: • Document.PageActivate You can also use event handlers to respond to events that are triggered by deactivating a page: • Document.PageChange Reordering pages A page can be moved to another location in a document by using its MoveTo method. The following VBA code moves page 2 to the position of page 4: ActiveDocument.Pages(2).MoveTo 4 Activating a page in an inactive document does not activate that document. To activate a document, you must use its Activate method (see “Activating documents” on page 83). Understanding the Corel DESIGNER and CorelDRAW object models 96 Sizing pages You can specify the size and orientation of pages, specifying the default page size, and use defined page sizes. Specifying the size and orientation of pages You can size a page by using its SetSize method, which applies two size values (width and height) to the page. The following VBA code changes the size of the active page in the active document to A4: ActiveDocument.Unit = cdrMillimeter ActivePage.SetSize 210, 297 ActivePage.Orientation = cdrLandscape For the SetSize method, the first number is always the page width and the second number is always the page height. Reversing the two numbers switches the orientation of the page. Specifying the default page size The default page size for a document is determined by the value of the item that has an index of 0 in the Document.Pages collection. You can specify the default page size by changing the value of this item: Dim doc As Document Set doc = ActiveDocument doc.Unit = cdrMillimeter doc.Pages(0).SetSize 297, 210 Alternatively, you can use the Document.MasterPage property to specify the default page size: Dim doc As Document Set doc = ActiveDocument doc.Unit = cdrMillimeter doc.MasterPage.SetSize 297, 210 Using defined page sizes Page sizes can be defined by either the application or the user. All defined page sizes are stored in the Application.PageSizes collection, and the name of each PageSize object in that collection is defined by its Name property: Dim pageSizeName As String pageSizeName = Application.PageSizes(3).Name Page sizes can be specified by name. For example, the following VBA code gets the PageSize object named “Business Card”: Dim thisSize As PageSize Set thisSize = Application.PageSizes("Business Card") Understanding the Corel DESIGNER and CorelDRAW object models 97 You can get the actual dimensions of a PageSize object by using its Width and Height properties. The following VBA code retrieves the width and height (in millimeters) of the third PageSize object: Dim pageWidth As Double, pageHeight As Double Application.Unit = cdrMillimeter pageWidth = Application.PageSizes(3).Width pageHeight = Application.PageSizes(3).Height Although each PageSize object provides a Delete method, this method can be used only on user-defined page sizes. You can determine whether a PageSize object is user-defined by testing its BuiltIn Boolean property: Public Sub deletePageSize(thisSize As PageSize) If Not thisSize.BuiltIn Then thisSize.Delete End Sub You can specify a particular unit of measurement for a page size by setting the units for the document before getting its width and height. Modifying pages You can modify a page regardless of whether it is active. Activating a page in an inactive document does not activate that document. To activate a document, you must use its Activate method (see “Activating documents” on page 83). By explicitly referencing the page that you want to modify, you can make those changes without activating the page. The following VBA code deletes all shapes on page 3 of the active document without activating that page: Public Sub DeleteShapesFromPage3() Dim doc As Document Set doc = ActiveDocument doc.Pages(3).Shapes.All.Delete End Sub Deleting pages You can delete a page by using its Delete method, as in the following VBA example: ActivePage.Delete The Page.Delete method deletes all shapes on that page, deletes the page from the Pages collection for that document, and then updates that collection to reflect the change. If you want to delete more than one page, you must use the Delete method for each unwanted page. However, you cannot delete all pages in a document. You can avoid trying to delete the last remaining page in a document by using the following VBA code: If ActiveDocument.Pages.Count > 1 Then ActivePage.Delete Understanding the Corel DESIGNER and CorelDRAW object models 98 If you want, you can use event handlers to respond to events that are triggered by deleting a page: • Document.PageDelete Working with layers Layers are invisible planes that let you organize the objects on a page. You can group related objects into layers, and you can change the vertical order (or “stacking order”) of those layers to change the appearance of the page. Master layers apply to all pages in a document, while local layers apply to a single page. Each layer, or Layer object, is a member of the Page.Layers collection for the page on which it appears. The layers in a Page.Layers collection appear in the order in which they appear on that page — the first layer is the one at the top of the “stack,” and the last layer is the one at the bottom. If layers are added, reordered, or deleted, the affected Page.Layers collection is immediately updated to reflect the new layer order of that page. Corel DESIGNER and CorelDRAW provide a number of properties, methods, and events for working with layers, the most useful of which are listed in the following table. Class Member Description Document ActiveLayer property Provides direct access to the active layer for a document For more information, see “Activating layers” on page 101. Document LayerActivate event Is triggered when a layer is activated For more information, see “Activating layers” on page 101. Document LayerChange event Is triggered when a layer is deactivated For more information, see “Activating layers” on page 101. Document LayerCreate event Is triggered when a layer is created For more information, see “Creating layers” on page 100. Document LayerDelete event Is triggered when a layer is deleted For more information, see “Deleting layers” on page 103. Layer Activate method Activates a layer For more information, see “Activating layers” on page 101. Layer Delete method Deletes a layer For more information, see “Deleting layers” on page 103. Layer Editable property Controls whether a layer is editable For information, see “Locking and hiding layers” on page 101. Layer Import method or ImportEx method Imports a file into a layer For information, see “Importing files into layers” on page 102. Understanding the Corel DESIGNER and CorelDRAW object models 99 Class Member Description Layer MoveAbove method or MoveBelow method Moves a layer Name property Specifies the name of a layer Layer For information, see “Reordering layers” on page 101. For information, see “Renaming layers” on page 102. Layer Visible property Controls whether the contents of a layer are visible For information, see “Locking and hiding layers” on page 101. Page ActiveLayer property Provides direct access to the active layer for a page For more information, see “Activating layers” on page 101. Page CreateLayer method Inserts a new layer at the top of the list of non-master layers For more information, see “Creating layers” on page 100. Page Layers property Contains the collection of layers for a page For more information, see “Activating layers” on page 101. For detailed information on any property, method, or event, see “Object Model Reference” section in the Macros Help file for the application. For more information on layer-related activities, see the following topics: • “Creating layers” on page 100 • “Activating layers” on page 101 • “Locking and hiding layers” on page 101 • “Reordering layers” on page 101 • “Renaming layers” on page 102 • “Importing files into layers” on page 102 • “Deleting layers” on page 103 Creating layers You can create a layer by using the Page.CreateLayer method. Creating a layer inserts a new layer at the top of the list of non-master layers. The following VBA code creates a new layer called “My New Layer”: ActivePage.CreateLayer "My New Layer" If you want, you can use event handlers to respond to events that are triggered by activating a layer: • Document.LayerCreate Understanding the Corel DESIGNER and CorelDRAW object models 100 Activating layers Each layer is a member of the Page.Layers collection for the page on which it appears. The layers in a Page.Layers collection appear in the order in which they appear on that page — the first layer is the one at the top of the “stack,” and the last layer is the one at the bottom. If layers are added, reordered, or deleted, the affected Page.Layers collection is immediately updated to reflect the new layer order of that page. The Document.ActiveLayer property provides direct access to the active layer for a document, while the Page.ActiveLayer property provides direct access to the active layer for a page. You can activate a layer by using the Layer.Activate method: ActivePage.Layers("Layer 1").Activate Activating a locked layer does not unlock it. Similarly, activating a hidden layer does not make it visible. For information on unlocking and displaying layers, see “Locking and hiding layers” on page 101. If you want, you can use event handlers to respond to events that are triggered by activating a layer: • Document.LayerActivate You can also use event handlers to respond to events that are triggered by deactivating a layer: • Document.LayerChange Locking and hiding layers Layer objects feature the properties Editable and Visible, which control (respectively) whether the layer is editable and whether its contents are visible. Both properties are Boolean. By setting both the properties to True, you unlock and display the layer for editing. By setting either property to False, however, you lock the layer such that it cannot be edited. The following sample VBA code locks, but displays, the layer on the active page: ActivePage.Layers("Layer 1").Visible = True ActivePage.Layers("Layer 1").Editable = False The result of any changes to these properties is immediately displayed in the Object Manager. The preceding example affects only the active page. You can access the layer settings for a given page by specifying a page from the Document.Pages collection, or by referencing the Document.ActivePage property. To make the changes to all pages in a document, use the Document.MasterPage property: ActiveDocument.MasterPage.Layers("Layer 1").Visible = True For more information on working with pages, see “Working with pages” on page 93. Reordering layers You can reorder layers by using the following two methods of the Layer class: MoveAbove and MoveBelow. Both methods move the specified layer above or below the layer that is referenced as a parameter. Understanding the Corel DESIGNER and CorelDRAW object models 101 The following VBA code moves the layer called “Layer 1” to immediately below the layer “Guides”: Dim pageLayers As Layers Set pageLayers = ActivePage.Layers pageLayers("Layer 1").MoveBelow pageLayers("Guides") The change is immediately reflected in the Object Manager (although it may be apparent only in the Layer Manager). Renaming layers You can rename a layer by editing its Name property. The following VBA code renames “Layer 1” as “Layer with a New Name”: ActivePage.Layers("Layer 1").Name = "Layer with a New Name" Importing files into layers Files of all supported formats can be imported. Files are imported at the Layer level because each imported object is assigned to a specified layer on a specified page. However, files are exported at the Document level because the range of exported objects can extend over multiple layers and multiple pages (see “Exporting files from documents” on page 88). The Layer class has two file-import methods: Import and ImportEx. The wide selection of supported file formats is due to the vast number of filters that are available to the application. Each filter lets you work with the files from another graphics application. To learn more about working with these filters, see “Working with import filters and export filters” on page 143. Understanding the Layer.Import method The Layer.Import method provides basic functionality for importing files. The following VBA code imports the file C:\logotype.gif into the active layer at the center of the page: ActiveLayer.Import "C:\logotype.gif" Importing a file selects the contents of that file and deselects any other selected objects in the document. You can therefore reposition or resize the imported objects by getting the document selection: ActiveDocument.Unit = cdrInch ActiveSelection.SetSize 3, 2 Some file formats can be imported by using one of several filters, so it is important to understand the benefits of each available filter. For example, when importing an Encapsulated PostScript (EPS) file, you can choose between the EPS filter and the PDF filter. The EPS filter lets you do the following: • import an EPS file as a placeable object that can be printed but not modified • interpret the PostScript portion of the file, so that you can import the original artwork from within the file rather than its low-resolution header Understanding the Corel DESIGNER and CorelDRAW object models 102 To specify which filter to use, you can include the optional parameter Filter, as in the following VBA example: ActiveLayer.Import "C:\map.eps", cdrPSInterpreted Understanding the Layer.ImportEx method The Layer.ImportEx method provides much better control over the import filter through its optional use of a StructImportOptions object. The following VBA code imports the specified file as a linked file: Dim iFilt As ImportFilter Dim importProps As New StructImportOptions importProps.LinkBitmapExternally = True Set iFilt = ActiveLayer.ImportEx("C:\world-map.epsf", cdrAutoSense, importProps) iFilt.Finish Deleting layers As previously discussed, each layer is a member of the Page.Layers collection for the page on which it appears. You can delete a layer by calling its Delete method. Deleting a layer removes that layer from the document, taking with it all shapes on that layer on all pages in the document. The following VBA code deletes the layer called “Layer 1”: ActivePage.Layers("Layer 1").Delete If you want, you can use event handlers to respond to events that are triggered by deleting a layer: • Document.LayerDelete Working with shapes Every document is made up of shapes, or Shape objects, which are created by using the drawing tools. Any changes that are made to the properties of a shape — such as by moving the shape, changing its size, or giving it a new fill — are immediately visible to the object model. The shapes on a document page are stored on layers. Each shape is a member of the Layer.Shapes collection for the layer on which it appears. The shapes in a Layer.Shapes collection appear in the order in which they appear on that layer — the first shape is the one at the top of the “stack,” and the last shape is the one at the bottom. If shapes are added, reordered, or deleted, the affected Layer.Shapes collection is immediately updated to reflect the new shape order of that layer. In addition, each document page has a Shapes collection, which contains all Layer.Shapes collections for that page. The first shape in a Page.Shapes collection is the one at the very top of that page, and the last shape is the one at the very bottom. Corel DESIGNER and CorelDRAW provide a number of properties, methods, and events for working with shapes, the most useful of which are listed in the following table.

For detailed information on any property, method, or event, see “Object Model Reference” section in the Macros Help file for the application. For more information on shape-related activities, see the following topics: • “Creating shapes” on page 114 • “Determining shape type” on page 126 • “Selecting shapes” on page 126 • “Duplicating shapes” on page 129 • “Transforming shapes” on page 130 • “Coloring shapes” on page 134 • “Applying effects to shapes” on page 139 • “Projecting shapes” on page 141 • “Searching for shapes” on page 143 • “Deleting shapes” on page 143 Creating shapes Every document is made up of shapes, or Shape objects, which are created by using the drawing tools. The shapes on a document page are stored on layers, so the various shape-creation methods belong to the Layer class. Understanding the Corel DESIGNER and CorelDRAW object models 114 For information on creating specific types of shapes, see the following subtopics: • “Creating rectangles” on page 115 • “Creating ellipses” on page 116 • “Creating lines and curves” on page 117 • “Creating text objects” on page 119 • “Creating dimension objects” on page 121 • “Creating symbols” on page 123 Supported shapes not discussed in this section include polygons (or Polygon objects) and customized shapes (or CustomShape objects). Customized shapes that are supported include callout shapes (or CalloutShape objects) and tables (or TableShape objects). Shapes are measured in document units. You can specify the unit of measurement for a document by using the Document.Unit property (see “Setting document properties” on page 84). If you want, you can use event handlers to respond to events that are triggered by creating a shape: • AddinHook.ShapeCreated • Document.ShapeCreate Creating rectangles You can add rectangles (or Rectangle objects) to your documents by using one of the following methods: • Layer.CreateRectangle • Layer.CreateRectangle2 • Layer.CreateRectangleRect These methods return a reference to the new Shape object. They differ only in the parameters that they take, so you can choose the method that best suits your macro solution. You can also use these rectangle-creation methods to create squares. The CreateRectangle method creates a rectangle by using four parameters that specify the following: • the distance between the left, top, right, and bottom sides of the rectangle (in that order) • the corresponding edges of the page frame The following VBA example uses the CreateRectangle method to create a 2" × 1" rectangle that is positioned 6" up from the bottom of the page frame and 3" in from the left side of the page frame: Dim sh As Shape ActiveDocument.Unit = cdrInch Set sh = ActiveLayer.CreateRectangle(3, 7, 6, 5) The CreateRectangle2 method creates a rectangle based on the coordinates of its lower-left corner, its width, and its height. Understanding the Corel DESIGNER and CorelDRAW object models 115 The following VBA example uses the CreateRectangle2 method to create the same rectangle as the previous example: Dim sh As Shape ActiveDocument.Unit = cdrInch Set sh = ActiveLayer.CreateRectangle2(3, 6, 2, 1) Finally, the CreateRectangleRect method creates a rectangle based on its bounding box (or Rect object). These three rectangle-creation methods provide optional parameters for specifying corner roundness. The CreateRectangle method specifies corner roundness by using parameters for the upper-left, upper-right, lower-left, and lower-right corners (in that order). These parameters take integer values (which range from the default 0 to 100) that define the radius of the four corners as a whole-number percentage of half of the length of the shortest side. The following VBA example re-creates the 2" × 1" rectangle from the previous examples. However, this time, the four corner radii are set to 100%, 75%, 50%, and 0% of half of the length of the shortest side (that is, to 0.5", 0.375", 0.25", and a cusp): Dim sh As Shape ActiveDocument.Unit = cdrInch Set sh = ActiveLayer.CreateRectangle(3, 7, 6, 5, 100, 75, 50, 0) The CreateRectangle2 method and the CreateRectangleRect method define the corner radii in the same order as the CreateRectangle method (that is, upper-left, upper-right, lower-left, and lower-right). However, CreateRectangle2 and CreateRectangleRect take double (floating-point) values that measure the corner radii in document units. When using CreateRectangle2 or CreateRectangleRect, you must limit the size of the corner radii to less than half of the length of the shortest side of the rectangle. The following VBA example uses the CreateRectangle2 method to create the same round-cornered rectangle as the previous example: Dim sh As Shape ActiveDocument.Unit = cdrInch ActiveDocument.ReferencePoint = cdrBottomLeft Set sh = ActiveLayer.CreateRectangle2(3, 6, 2, 1, 0.5, 0.375, 0.25, _ 0) Creating ellipses You can add ellipses (or Ellipse objects) to your documents by using one of the following methods: • Layer.CreateEllipse • Layer.CreateEllipse2 • Layer.CreateEllipseRect These methods return a reference to the new Shape object. They differ only in the parameters that they take, so you can choose the method that best suits your macro solution. Understanding the Corel DESIGNER and CorelDRAW object models 116 You can also use the ellipse-creation methods to create circles, arcs, and pie shapes. The CreateEllipse method creates an ellipse by using four parameters that specify the following: • the distance between the left, top, right, and bottom sides of the ellipse (in that order) • the corresponding edges of the page frame The following VBA example creates a 50-millimeter circle: Dim sh As Shape ActiveDocument.Unit = cdrMillimeter Set sh = ActiveLayer.CreateEllipse(75, 150, 125, 100) The CreateEllipse2 method creates an ellipse based on its center point, its horizontal radius, and its vertical radius. (If only one radius is given, a circle is created.) The following VBA example uses the CreateEllipse2 method to create an ellipse: Dim sh As Shape ActiveDocument.Unit = cdrMillimeter Set sh = ActiveLayer.CreateEllipse2(100, 125, 50, 25) The following VBA example uses the CreateEllipse2 method to create the same 50-millimeter circle as the CreateEllipse example: Dim sh As Shape ActiveDocument.Unit = cdrMillimeter Set sh = ActiveLayer.CreateEllipse2(100, 125, 25) Finally, the CreateEllipseRect method creates an ellipse based on its bounding box (or Rect object). These three ellipse-creation methods provide three optional parameters for creating an arc or a pie shape. The StartAngle and EndAngle parameters — which are double values that are measured with zero being horizontally right on the page and with positive values being degrees from zero and moving counterclockwise — are used to define the start angle and end angle of the shape (respectively). In addition, the Pie parameter — which is a Boolean value — defines whether the shape is an arc (False) or a pie shape (True). The following VBA code uses the CreateEllipse method to create a “C” shape: Dim sh As Shape ActiveDocument.Unit = cdrMillimeter Set sh = ActiveLayer.CreateEllipse(75, 150, 125, 100, 60, 290, False) Creating lines and curves You can add lines and curves (or Curve objects) to your documents. To create a line or a curve, you must first create a Curve object “in memory” by using the Application.CreateCurve method. Each Curve object has at least one subpath (or SubPath object). You can add a subpath to a line or a curve by using the Curve.CreateSubPath method. Understanding the Corel DESIGNER and CorelDRAW object models 117 Each SubPath object has at least one segment (or Segment object), which can be line-type or curve-type. You can add a line-type segment to the end of a subpath by using the SubPath.AppendLineSegment method; you can add a curve-type segment by using the SubPath.AppendCurveSegment method or the SubPath.AppendCurveSegment2 method. The SubPath.AppendLineSegment method requires one set of Cartesian coordinates, which defines the end of the new segment. The SubPath.AppendCurveSegment method requires one set of Cartesian coordinates, which defines the end of the new segment. Optionally, you can specify two sets of polar coordinates if you want to define the lengths and angles of the starting and ending control handles for the segment. The SubPath.AppendCurveSegment2 method requires three sets of Cartesian coordinates: one to define the end of the new segment, and two to define the positions of the starting and ending control handles for the segment. You can add a segment to the beginning of a subpath by setting the AppendAtBeginning parameter for the segment-creation method to True. Finally, each Segment object has at least one node (or Node object). You can add a node to a segment by using the Segment.AddNodeAt method. You can close a Curve object by setting its Closed property to True. After creating a curve “in memory,” you can apply it to a layer by using the Layer.CreateCurve method. A reference to the new Shape object is returned. The following VBA code creates a D-shaped curve that is closed: Dim sh As Shape, spath As SubPath, crv As Curve ActiveDocument.Unit = cdrCentimeter Set crv = Application.CreateCurve(ActiveDocument) 'Create Curve object Set spath = crv.CreateSubPath(6, 6) ' Create a SubPath spath.AppendLineSegment 6, 3 ' Add the short vertical segment spath.AppendCurveSegment 3, 0, 2, 270, 2, 0 ' Lower curve spath.AppendLineSegment 0, 0 ' Bottom straight edge spath.AppendLineSegment 0, 9 ' Left straight edge spath.AppendLineSegment 3, 9 ' Top straight edge spath.AppendCurveSegment 6, 6, 2, 0, 2, 90 ' Upper curve spath.Closed = True ' Close the curve Set sh = ActiveLayer.CreateCurve(crv) ' Create curve shape The Layer class provides three additional methods that act as shortcuts for creating a basic line or basic curve that has a single segment on a single subpath: • Layer.CreateLineSegment — creates a basic line based on the given starting point and ending point Understanding the Corel DESIGNER and CorelDRAW object models 118 • Layer.CreateCurveSegment — creates a basic curve based on the given starting point and ending point and, optionally, on the lengths and angles of the starting and ending control handles for the curve • Layer.CreateCurveSegment2 — creates a basic curve based on the given starting point and ending point and on the given positions of the starting and ending control handles for the curve These three methods return a reference to the new Shape object. Creating text objects You can add text (or Text objects) to your documents. Two types of text are supported: artistic text and paragraph text. An artistic-text object is a short line of text to which you can apply graphical effects. In contrast, a paragraph-text object is a large block of text — stored in a rectangular container called a “frame” — to which you can apply more complex formatting. To create an artistic-text object, you can use one of the following methods: • Layer.CreateArtisticText — creates basic artistic text • Layer.CreateArtisticTextWide — creates artistic text that is in Unicode format Both of these methods require you to specify the position and content of the artistic-text object. Optionally, both of these methods let you set such text attributes as font style, font size, formatting, and alignment. In addition, both of these methods return a reference to the new Shape object. The following VBA code uses the CreateArtisticText method to create a basic artistic-text object that places the words “Hello World” at the specified position: Dim sh As Shape ActiveDocument.Unit = cdrInch Set sh = ActiveLayer.CreateArtisticText(1, 4, "Hello World") You can fit artistic text to a path by using the Text.FitTextToPath method, which simply attaches the text to the outline of a shape such that the text flows along the path of that shape. The following VBA code creates a new artistic-text object and attaches it to the selected shape: Dim sh As Shape, sPath As Shape ActiveDocument.Unit = cdrInch Set sPath = ActiveShape Set sh = ActiveLayer.CreateArtisticText(1, 4, "Hello World") sh.Text.FitToPath sPath To create a paragraph-text object, you can use one of the following methods: • Layer.CreateParagraphText — creates basic paragraph text • Layer.CreateParagraphTextWide — creates paragraph text that is in Unicode format Both of these methods require you to specify the size of the paragraph-text frame by setting its position from the left, top, right, and bottom sides of the page frame (in that order). Optionally, both of these methods let you specify the desired text and set such text attributes as font style, font size, formatting, and alignment. In addition, both of these methods return a reference to the new Shape object. Understanding the Corel DESIGNER and CorelDRAW object models 119 The following VBA code uses the CreateParagraphText method to create a basic paragraph-text object that centers the words “Hi There” in a frame of the specified size: Dim sh As Shape ActiveDocument.Unit = cdrInch Set sh = ActiveLayer.CreateParagraphText(1, 4, 5, 2, "Hi There", _ Alignment := cdrCenterAlignment) You can format existing paragraph text by using text ranges (or TextRange objects). Text ranges are handled in two ways, both of which involve frames (or TextFrame objects): • “frames” method — The Text.Frames property represents a series of text frames, each of which has its own text range. • “story” method — The Text.Story property represents a text range that includes all text in a series of text frames. A text range can be treated as a single block of text, such that any changes to text properties (such as font style and font size) are applied to all text in that text range. Alternatively, a text range can be broken down into the following smaller text ranges: • columns (or TextColumns objects) • paragraphs (or TextParagraphs objects) • lines (or TextLines objects) • words (or TextWords objects) • characters (or TextCharacters objects) The object model supports all paragraph-formatting options and character-formatting options that are offered by the application. The following VBA code formats the specified text range by using the Text.Story property. The first paragraph of the story is changed to a heading style and the second and third paragraphs into a body-text style: Dim txt As TextRange ' Format the first paragraph Set txt = ActiveShape.Text.Story.Paragraphs(1) txt.ChangeCase cdrTextUpperCase txt.Font = "Verdana" txt.Size = 18 txt.Bold = True ' Format the second and third paragraphs Set txt = ActiveShape.Text.Story.Paragraphs(2, 2) txt.Font = "Times New Roman" txt.Size = 12 txt.Style = cdrNormalFontStyle You can place selected text inside closed shapes by using the Shape.PlaceTextInside method. Understanding the Corel DESIGNER and CorelDRAW object models 120 The following VBA code creates a 5" × 2" ellipse and places the selected text inside it: Dim txt As Shape, sh As Shape ActiveDocument.Unit = cdrInch Set txt = ActiveShape Set sh = ActiveLayer.CreateEllipse(0, 2, 5, 0) sh.PlaceTextInside txt Creating dimension objects You can add dimension objects (or Dimension objects) to your Corel DESIGNER documents. Dimension objects let you display the size of a shape or the distance or angle between multiple shapes. Dimension objects are widely used in both technical illustration and computer-aided design (CAD). A dimension object consists of two parts: • a line that demarcates the area — linear or angular — to be measured • text that displays the measurement of the dimension line Corel DESIGNER supports both linear dimension objects (or DimensionLinear objects) and angular dimension objects (or DimensionAngular objects). You can create dimension objects by using the following methods: • Layer.CreateLinearDimension — creates a linear dimension object • Layer.CreateAngularDimension — creates an angular dimension object The properties of a dimension object are set upon its creation. However, you can adjust those properties at any time by accessing the various properties of the corresponding DimensionLinear object or DimensionAngular object. You can link a dimension object to its target shape, such that the dimension line and its measurement are updated as the shape is manipulated. To create a linked dimension object, you must assign the end points of the dimension line to the snap points of the target shape. The following VBA example illustrates the concept of a linked dimension object. A linear dimension object and an angular dimension object are created and then linked to the specified rectangle. If the rectangle is moved, the dimension lines continue to “stick” to the snap points; if the rectangle is resized, the dimension measurements change accordingly. Sub Example1() Dim shp1 As Shape, shp2 As Shape, shp3 As Shape Dim Vertex As New SnapPoint ' Create a rectangle Application.Unit = cdrInch ActiveDocument.Unit = cdrInch Set shp1 = ActiveLayer.CreateRectangle2(0, 0, 5, 2.5) ' Create a linear dimension that is linked to snap points of the ' rectangle and get a reference to the Dimension object Set shp2 = _ ActiveLayer.CreateLinearDimension(cdrDimensionVertical, _ Understanding the Corel DESIGNER and CorelDRAW object models 121 shp1.SnapPoints(2), shp1.SnapPoints(3), TextX:=2) ' Modify the properties of the dimension object With shp2.Dimension 'Set the dimension's units to inches and display them .Linear.Units = cdrInch .Linear.ShowUnits = True End With ' Create an angular dimension on the rectangle's other snap points ' and set its properties at creation time Vertex.PositionX = ActiveDocument.DrawingOriginX - 2 Vertex.PositionY = ActiveDocument.DrawingOriginY Set shp3 = ActiveLayer.CreateAngularDimension(Vertex, _ shp1.SnapPoints(2), shp1.SnapPoints(3), 0, 0, _ Precision:=3, ShowUnits:=True, _ Units:=cdrDimensionUnitDegrees, OutlineWidth:=0.014, _ Arrows:=ArrowHeads(1), TextSize:=10) End Sub Alternatively, you can create a static dimension object that is not linked to any shape, such that the dimension line and its measurement do not change as the shapes in the document are manipulated. To create a static dimension object, you must create free snap points on the layer and then attach the dimension line to those snap points. The following VBA example illustrates the concept of a static dimension object. The dimension object is not linked to any shape, so it measures a static distance. Only changing the location of the free snap points for the dimension line modifies the measurement of the dimension object. Sub Example2() Dim Shape1 As Shape Dim Snap1 As New SnapPoint, Snap2 As New SnapPoint 'Initialize the snap points on the canvas Snap1.PositionX = 0 Snap1.PositionY = 0 Snap2.PositionX = 0 Snap2.PositionY = 10 'Create a linear dimension linked to the rectangle's snap points 'and get a reference to the dimension object Set Shape1 = _ ActiveLayer.CreateLinearDimension(cdrDimensionVertical, _ Snap1, Snap2) ' Modify the dimension object's properties Understanding the Corel DESIGNER and CorelDRAW object models 122 With Shape1.Dimension 'Set the dimension's units to inches and display them .Linear.Units = cdrInch .Linear.ShowUnits = True End With End Sub Creating symbols A symbol (or Symbol object) is a reusable graphic element that is defined in a symbol library. Using symbols in your documents provides the following benefits: • lower file-size — Each symbol is defined only once, regardless of how many actual instances of that symbol appear in the document. • increased productivity — Any changes made to a symbol definition are automatically propagated to all instances of that symbol in the document. • improved workflow — Symbol libraries are a convenient way to store and reuse common graphic elements. Symbol libraries come in two varieties: external and internal. External symbol libraries use the filename extension CSL and contain symbol definitions that must be manually added to the workspace at the application level. You cannot modify a symbol that is defined in an external library unless you open the associated external library (CSL) file; simply importing the file as a library does not let you modify its contents. External symbol libraries must be published to a location that all users can access. A common mapped drive is a good solution, but a corporate intranet is a better one. However, if the security of the symbols is not important, the best solution is a corporate Internet site. Internal symbol libraries exist at the document level. Defining a new symbol in a document — or adding an instance of an external-library symbol to a document — automatically adds that symbol to the internal library for that document. For this reason, each document has its own unique internal symbol library. Inserting an instance of a symbol from an external symbol library creates a link to the definition for that symbol in that external symbol library. If, at any point, the document cannot access the external symbol library, the symbol definition in the internal symbol library for that document is used instead. The Application.SymbolLibraries property contains the collection of all external symbol libraries (or SymbolLibrary objects) that are available to the application; the Document.SymbolLibrary property returns just the internal symbol library for that document. The SymbolLibrary.Symbols property contains the collection of all symbol definitions (or SymbolDefinition objects) in that symbol library. A SymbolDefinition object is also returned by the Symbol.Defintion property; therefore, you can modify the defintion of a symbol by using the various properties and methods of the SymbolDefinition class. To remove a symbol definition from the internal symbol library for a document, you must delete all instances of the symbol from the document and then run the SymbolLibrary.PurgeUnusedSymbols method. Simply removing all instances of a symbol from a document does not automatically remove its symbol definition from the internal symbol library for that document. Understanding the Corel DESIGNER and CorelDRAW object models 123 The following VBA code demonstrates the basics of using symbols: Sub AddRemoveSymbols() Dim objSymLibSwitchA As SymbolLibrary Dim shpSymBreaker2 As Shape, shpSymBreaker2A As Shape ActiveDocument.Unit = cdrMillimeter 'Add the switchesA external symbol library to the global 'workspace. Set objSymLibSwitchA = SymbolLibraries.Add _ ("C:\libs\switches\switchesA.csl") 'Add the breaker2 symbol to the active layer. 'NOTE: This automatically adds the symbol definition to the 'internal symbol library for the document. Set shpSymBreaker2 = ActiveLayer.CreateSymbol(15, 20, _ "breaker2", SymbolLibraries("switchesA")) 'Add another instance of the breaker2 symbol, this time from the 'internal symbol library. NOTE: We did not specify a library, so 'the library for the local document is used by default. Set shpSymBreaker2A = ActiveLayer.CreateSymbol(30, 20, _ "breaker2") 'Remove the switchesA library from the global workspace. SymbolLibraries("switchesA").Delete 'Delete the two breaker2 symbols. shpSymBreaker2.Delete shpSymBreaker2A.Delete 'At this point, the internal symbol library for the document 'still has the definition of breaker2 stored. To remove this 'definition, we must purge the unused symbols from the library. 'The definition is unused because there are no instances that 'reference it. ActiveDocument.SymbolLibrary.PurgeUnusedSymbols End Sub A symbol can contain (or “nest”) other symbols. A top-level symbol can contain symbols, and each of those symbols can contain a symbol, and so forth. In the object model, the SymbolDefinition.NestedSymbols property returns (as a SymbolDefinitions object) the collection of nested symbols for a symbol definition. While there is no restriction on how many nesting levels can be created, the symbol cannot be rendered without access to its symbol definition (whether external or internal). In addition, even if the first and second nesting layers of a symbol are rendered correctly, a symbol on the third nesting layer may not be rendered correctly without access to its required symbol definition. Understanding the Corel DESIGNER and CorelDRAW object models 124 Symbols and nested symbols The following VBA code demonstrates the basics of using nested symbols: Sub MakeNestedSymbol() Dim shp1 As Shape, shp2 As Shape, shp3 As Shape, shpSym As Shape Dim shpRng As New ShapeRange 'Create a pair of rectangles and a circle. Set shp1 = ActiveLayer.CreateRectangle2(0, 0, 10, 20) Set shp2 = ActiveLayer.CreateRectangle2(50, 50, 20 ,10) Set shp3 = ActiveLayer.CreateEllipse(10, 10, 20) 'Make a symbol out of the circle. NOTE: This circle is 'automatically added to the internal symbol library for the 'document. Set shpSym = shp3.ConvertToSymbol("circle") 'Add the rectangles and the circle symbol to a shape range. shpRng.Add shp1 shpRng.Add shp2 shpRng.Add shpSym 'Convert the shape range into a symbol. NOTE: This symbol is 'added to the internal symbol library for the document. It is 'also is a nested symbol because it contains the symbol circle. shpRng.ConvertToSymbol "shapes" End Sub Understanding the Corel DESIGNER and CorelDRAW object models 125 Determining shape type Each Shape object has a read-only Type property, which returns the shape type (for example, rectangle, ellipse, curve, text, or group). The properties and methods that are available to a shape vary with shape type; therefore, it’s a good idea to determine the shape type before applying any properties or methods to that shape. The following sample VBA code determines whether a shape is text. If the shape is text, the code determines whether it is artistic text or paragraph text. If the shape is artistic text, it is rotated by 10 degrees. Dim sh As Shape Set sh = ActiveShape If sh.Type = cdrTextShape Then If sh.Text.IsArtisticText = True Then sh.Rotate 10 End If End If Selecting shapes Each shape is a member of the Layer.Shapes collection for the layer on which it appears. The shapes in a Layer.Shapes collection appear in the order in which they appear on that layer — the first shape is the one at the top of the “stack,” and the last shape is the one at the bottom. If shapes are added, reordered, or deleted, the affected Layer.Shapes collection is immediately updated to reflect the new shape order of that layer. In addition, each document page has a Shapes collection, which contains all Layer.Shapes collections for that page. The first shape in a Page.Shapes collection is the one at the very top of that page, and the last shape is the one at the very bottom. If you want to access individual shapes, you can select them. When you select shapes, you create a “selection” that contains only those shapes. The Shape.Selected property takes a Boolean value that indicates whether a shape is selected: True if the shape is selected, False otherwise. You can select a shape by changing the value of its Selected property to True; this technique adds the shape to the current selection — that is, rather than creating a new selection that contains only that shape. If you want to create a new selection from a shape — that is, by selecting a specified shape and deselecting any other selected shapes — you can use the Shape.CreateSelection method, as in the following VBA example: Dim sh As Shape Set sh = ActivePage.Shapes(1) If sh.Selected = False Then sh.CreateSelection You can select multiple shapes by using the ShapeRange.CreateSelection method. The following VBA code uses this method — in combination with the Shapes.All method — to select all shapes on the active page (except those on locked or hidden layers): ActivePage.Shapes.All.CreateSelection Understanding the Corel DESIGNER and CorelDRAW object models 126 You can access a selection in one of two ways: • Use the Document.Selection method to return a special Shape object that contains the actual selection. This Shape object is automatically refreshed when the selection is updated. • Use the Document.SelectionRange property to return a ShapeRange object that contains a copy of the selection. This ShapeRange object represents a “snapshot” of the selection (at the time when the ShapeRange object was created), so it is not automatically refreshed when the selection is updated. To summarize, you can access a selection directly, or you can access a copy of that selection; alternatively, you can access a subset of the shapes in a selection. You can also reorder the shapes in a selection. When you no longer require a selection, you can deselect one or all of its shapes. For more information on selecting shapes, see the following subtopics: • “Accessing selections directly” on page 127 • “Accessing copies of selections” on page 128 • “Accessing the shapes in a selection” on page 128 • “Reordering the shapes in a selection” on page 129 • “Deselecting shapes” on page 129 Accessing selections directly As previously discussed, you can use the Document.Selection method to access the contents of a selection directly. A Shape object is returned, and this Shape object is updated to reflect any changes made to the selection. The following VBA code returns the selection for the active document: Dim sel As Shape Set sel = ActiveDocument.Selection The shortcut for ActiveDocument.Selection is ActiveSelection, which returns a Shape object of subtype cdrSelectionShape. The Shape subtype has a member collection called Shapes, which represents a collection of all the selected shapes in the document. The shapes in the ActiveSelection.Shapes collection can be accessed as in the following VBA example: Dim sh As Shape, shs As Shapes Set shs = ActiveSelection.Shapes For Each sh In shs sh.Rotate 15 'Rotate each shape by 15 degrees counterclockwise Next sh After you use the ActiveSelection command to select shapes, you cannot subsequently use the command to access those shapes. Instead, you must create a copy of the selection by using one of the following methods: • Recreate the selection as an array of Shape objects. • Recreate the selection as a Shapes collection. • Create a “snapshot” of the selection as a ShapeRange object (see “Accessing copies of selections” on page 128). Understanding the Corel DESIGNER and CorelDRAW object models 127 Accessing copies of selections As previously discussed, you can use the Document.SelectionRange property to make a copy of the shapes in a selection. However, the returned ShapeRange object is not refreshed when the selection is updated because it represents a “snapshot” of the selection at the moment when that ShapeRange object was created. The following VBA code returns a copy of the selection for the active document: Dim selRange As ShapeRange Set selRange = ActiveDocument.SelectionRange The shortcut for the ActiveDocument.SelectionRange command is ActiveSelectionRange, which returns a ShapeRange object. This object contains a collection of references to the shapes that were selected at the moment when the property was invoked. The shapes in the ActiveSelectionRange collection can be accessed as in the following VBA example: Dim sh As Shape, shRange As ShapeRange Set shRange = ActiveSelectionRange For Each sh In shRange sh.Skew 15 ' Skew each shape thru 15° counterclockwise Next sh After you use the ActiveSelectionRange command to create a copy of the current document selection, you can subsequently access the returned ShapeRange object to access any of its shapes. You can even add shapes to or remove shapes from the returned ShapeRange object. You can then use the ShapeRange.CreateSelection method if you want to replace the current selection with the modified ShapeRange object. The following VBA code creates a ShapeRange object from the current document selection, removes the first and second shapes from that shape range, and then replaces the original selection with this modified ShapeRange object: Dim shRange As ShapeRange Set shRange = ActiveSelectionRange shRange.Remove 1 shRange.Remove 2 shRange.CreateSelection If you want to add a specified ShapeRange object to the current selection (rather than use it to replace the current selection), you can use the ShapeRange.AddToSelection method. Accessing the shapes in a selection You can use a similar process for accessing the shapes in a selection as you can for accessing the shapes in a selection range. Here is a a VBA code sample for accessing the shapes in a selection: Dim shs As Shapes, sh As Shape Set shs = ActiveSelection.Shapes For Each sh In shs ' Do something with the shape, sh Next sh Understanding the Corel DESIGNER and CorelDRAW object models 128 Here is a VBA code sample for accessing the shapes in a selection range: Dim sRange As ShapeRange, sh As Shape Set sRange = ActiveSelectionRange For Each sh In sRange ' Do something with the shape, sh Next sh Remember that the ActiveSelection.Shapes command provides direct access to the current selection, while the ActiveSelectionRange command provides a copy of the current selection. Use ActiveSelection.Shapes if you want to access the current selection; use ActiveSelectionRange if you want to create a “snapshot” of the current selection that you can access later. Reordering the shapes in a selection The ActiveSelection.Shapes command and the ActiveSelectionRange command return shapes in the reverse order from which they were selected: the first shape is the last one selected, and the last shape is the first one selected. Please keep this fact in mind when reordering the shapes in a selection. Deselecting shapes You can deselect any shape by changing the value of its Shape.Selected property to False. You can deselect all shapes by using the Document.ClearSelection method. The following VBA code uses the ClearSelection method to deselect all shapes in the active document: ActiveDocument.ClearSelection If you want, you can use event handlers to respond to events that are triggered by deseleting a shape: • Document.ShapeChange You can also use event handlers to respond to events that are triggered by deactivating a selection: • Application.SelectionChange • Document.SelectionChange • GlobalMacroStorage.SelectionChange Duplicating shapes You can use the Shape.Duplicate method to duplicate a shape, and you can use the ShapeRange.Duplicate method to duplicate a range of shapes. ActiveSelection.Duplicate The Duplicate method provides two optional parameters, OffsetX and OffsetY, which offset the duplicate from the original (horizontally and vertically, respectively). The following VBA code positions the duplicate two inches to the right and one inch above the original: ActiveDocument.Unit = cdrInch ActiveSelection.Duplicate 2, 1 Understanding the Corel DESIGNER and CorelDRAW object models 129 Transforming shapes You can transform shapes in various ways, as explained in the following topics: • “Sizing shapes” on page 130 • “Stretching shapes” on page 132 • “Skewing shapes” on page 132 • “Rotating shapes” on page 132 • “Positioning shapes” on page 133 If you want, you can use event handlers to respond to events that are triggered by transforming a shape: • Document.ShapeTransform Sizing shapes You can return the width and height of a shape (in document units) by using the Shape.SizeWidth and Shape.SizeHeight properties, as in the following VBA example: Dim width As Double, height As Double ActiveDocument.Unit = cdrMillimeter width = ActiveShape.SizeWidth height = ActiveShape.SizeHeight You can also use the Shape.SizeWidth and Shape.SizeHeight properties to resize an existing shape by specifying new values for those properties. The following VBA example uses these properties to set the size of the active shape to a width of 50 millimeters and a height of 70 millimeters: ActiveDocument.Unit = cdrMillimeter ActiveShape.SizeWidth = 50 ActiveShape.SizeHeight = 70 You can return both the width and the height of a shape (in document units) by using the Shape.GetSize method, as in the following VBA example: Dim width As Double, height As Double ActiveDocument.Unit = cdrMillimeter ActiveShape.GetSize width, height You can resize a shape by using the Shape.SetSize method to specify a new width and new height for it, as in the following VBA example: ActiveDocument.Unit = cdrMillimeter ActiveShape.SetSize 50, 70 You can also resize a shape by using the Shape.SetSizeEx method. Besides the new width and new height for the shape, this method takes a reference point for the resize (instead of using the center point of the shape). The following VBA code uses the SetSizeEx method to resize the current selection to 10 inches wide by 8 inches high about the reference point (6, 5) in the document: ActiveDocument.Unit = cdrInch ActiveSelection.SetSizeEx 6, 5, 10, 8 Understanding the Corel DESIGNER and CorelDRAW object models 130 If you want to take the outline of a shape into account when returning the size of that shape, you must use the Shape.GetBoundingBox method. The bounding box for a shape surrounds both the shape and its outline; however, the actual dimensions of a shape specify its width and height irrespective of the size of its outline. The following VBA example uses the GetBoundingBox method to return the size of the active shape: Dim width As Double, height As Double Dim posX As Double, posY As Double ActiveDocument.Unit = cdrInch ActiveDocument.ReferencePoint = cdrBottomLeft ActiveShape.GetBoundingBox posX, posY, width, height, True The Shape.GetBoundingBox method takes parameters that specify the position of the lower-left corner of the shape, the width of the shape, and the height of the shape. The final parameter is a Boolean value that indicates whether to include (True) or exclude (False) the outline of the shape. The Shape.SetBoundingBox method lets you set the size of a shape by specifying the size of its bounding box; however, this method lacks the parameter for specifying whether to include the outline in the new size. If you want to calculate the size and position of the bounding box of a shape without including its outline, you can use the GetBoundingBox method twice (once including the outline and once excluding it), as in the following VBA example: Public Sub SetBoundingBoxEx(X As Double, Y As Double, _ Width As Double, Height As Double) Dim sh As Shape Dim nowX As Double, nowY As Double Dim nowWidth As Double, nowHeight As Double Dim nowXol As Double, nowYol As Double Dim nowWidthol As Double, nowHeightol As Double Dim newX As Double, newY As Double Dim newWidth As Double, newHeight As Double Dim ratioWidth As Double, ratioHeight As Double Set sh = ActiveSelection sh.GetBoundingBox nowX, nowY, nowWidth, nowHeight, False sh.GetBoundingBox nowXol, nowYol, nowWidthol, nowHeightol, True ratioWidth = Width / nowWidthol ratioHeight = Height / nowHeightol newWidth = nowWidth * ratioWidth newHeight = nowHeight * ratioHeight newX = X + (nowX - nowXol) newY = Y + (nowY - nowYol) sh.SetBoundingBox newX, newY, newWidth, newHeight, False, _ cdrBottomLeft End Sub Understanding the Corel DESIGNER and CorelDRAW object models 131 Stretching shapes You can stretch a shape (or scale it by stretching is proportionately) by using the Shape.Stretch method or the Shape.StretchEx method. Both methods take a decimal value for the stretch, where 1 is 100% (or no change); you cannot use zero, so you must use a very small value instead. The following VBA code uses the Shape.Stretch method to stretch the selection to half its current height and twice its width, about the midpoint of the bottom edge of its bounding box: ActiveDocument.ReferencePoint = cdrBottomMiddle ActiveSelection.Stretch 2, 0.5 If you want to specify the reference point about which to perform a stretch, you can use the Shape.StretchEx method. The following VBA code performs the same stretch as the previous code, but it performs that stretch about the point (4, 5) on the page (in inches): ActiveDocument.Unit = cdrInch ActiveSelection.StretchEx 4, 5, 2, 0.5 The Shape.Stretch and Shape.StretchEx methods provide an optional Boolean parameter that determines how to stretch paragraph text. A value of True stretches the characters, while False stretches the bounding box and re-flows the text within it. Skewing shapes You can skew a shape by using the Shape.Skew method or the Shape.SkewEx method. These methods let you specify the horizontal-skew angle (in degrees, where positive values move the top edge to the left and the bottom edge to the right) and the vertical-skew angle (in degrees, where positive values move the right edge upwards and the left edge downwards). Skews of angles close to or greater than 90° are not allowed. The horizontal skew is applied before the vertical skew. The difference between the Shape.Skew and Shape.SkewEx methods is the point about which the skew is performed: Skew uses the center of rotation for the shape, while SkewEx uses the specified reference point. You can determine the center of rotation for a shape by returning the values of its Shape.RotationCenterX and Shape.RotationCenterY properties. Changing these values moves the center of rotation for that shape. The following VBA code uses the Shape.Skew method to skew the selection (about its center of rotation) by 30° horizontally and by 15° vertically: ActiveSelection.Skew 30, 15 Rotating shapes You can rotate a shape by using the Shape.Rotate method or the Shape.RotateEx method. These methods rotate the shape by the given angle (in degrees). However, the difference between these methods is the point about which they perform the rotation: Rotate uses the center of rotation for the shape, while RotateEx uses the specified reference point. Understanding the Corel DESIGNER and CorelDRAW object models 132 You can determine the center of rotation for a shape by returning the values of its Shape.RotationCenterX and Shape.RotationCenterY properties. Changing these values moves the center of rotation for that shape. The following VBA code uses the Shape.Rotate method to rotate the selection (about its center of rotation) by 30°: ActiveSelection.Rotate 30 The following VBA code uses the Shape.RotateEx method to rotate each selected shape by 15° clockwise about its lower-right corner: Dim sh As Shape ActiveDocument.ReferencePoint = cdrBottomRight For Each sh In ActiveSelection.Shapes sh.RotateEx -15, sh.PositionX, sh.PositionY Next sh Positioning shapes You can return the horizontal and vertical position of a shape by using the Shape.PositionX and Shape.PositionY properties (respectively). Alternatively, you can use the Shape.GetPosition method to return both the horizontal position and the vertical position of a shape. You can use the Shape.GetBoundingBox method if you want to return the position of a shape, including its outline. For more information on this method, see “Sizing shapes” on page 130. The following VBA code uses the Shape.GetPosition method to return the position of the selection relative to the current reference point of the active document, which the code explicitly sets to the lower-left corner: Dim posX As Double, posY As Double ActiveDocument.ReferencePoint = cdrBottomLeft ActiveSelection.GetPosition posX, posY You can also use the Shape.PositionX and Shape.PositionY properties to set the horizontal and vertical position of a shape (respectively), thereby moving that shape to the specified position. Alternatively, you can use the Shape.SetPosition method to move a shape to specified horizontal and vertical position, or you can use the Shape.SetPositionEx method to move the shape to a specified point. You can also use the Shape.SetSizeEx and Shape.SetBoundingBox methods to set the position of a shape. For more information on these methods, see “Sizing shapes” on page 130. Understanding the Corel DESIGNER and CorelDRAW object models 133 The following VBA code uses the Shape.SetPosition method to set the position of the lower-right corner of each selected shape in the active document to (3, 2) in inches: Dim sh As Shape ActiveDocument.Unit = cdrInch ActiveDocument.ReferencePoint = cdrBottomRight For Each sh In ActiveSelection.Shapes sh.SetPosition 3, 2 Next sh If you want, you can use event handlers to respond to events that are triggered by positioning a shape: • Document.ShapeMove Coloring shapes You can add color to a shape by applying a fill (or Fill object) to it. The fill type for a shape is recorded by the Fill.Type property as one of the following constants for the cdrFillType enumeration: • cdrUniformFill — uniform fill • cdrFountainFill — fountain fill • cdrPatternFill — pattern fill • cdrTextureFill — texture fill • cdrPostScriptFill — PostScript fill • cdrHatchFill — hatch fill • cdrNoFill — no fill The following VBA code returns the type of fill that is applied to the active shape: Dim fillType As cdrFillType fillType = ActiveShape.Fill.Type You cannot change the fill type for a shape by modifying its Fill.Type property. Instead, you must use the appropriate Fill.Apply...Fill method, as described in the subsections that follow. You can also add color to a shape by applying an outline (or Outline object) to it. In addition, the object model provides a variety of properties and methods for working with the colors (or Color objects) that you apply to shapes. For information on applying fills and outlines and on working with colors, see the following subtopics: • “Applying uniform fills” on page 135 • “Applying fountain fills” on page 135 • “Applying pattern fills” on page 136 • “Applying texture fills” on page 136 • “Applying PostScript fills” on page 136 • “Applying hatch fills” on page 136 • “Applying outlines” on page 137 Understanding the Corel DESIGNER and CorelDRAW object models 134 • “Working with color” on page 138 In your macros, you can include queries that search for shapes that have specific fill properties, outline properties, or color properties. For information, see “Including queries in macros” in the Macros Help file for the application. Applying uniform fills Uniform fills consist of a single, solid color. A uniform fill is represented by the Fill.UniformColor property as a Color object. You can apply a uniform fill to a shape by using the Fill.ApplyUniformFill method. The following VBA example applies a red uniform fill to the active shape: ActiveShape.Fill.ApplyUniformFill CreateRGBColor(255, 0, 0) You can change the color of a uniform fill by modifying its Fill.UniformColor property. The following VBA example changes the uniform fill of the active shape to deep navy blue: ActiveShape.Fill.UniformColor.RGBAssign 0, 0, 102 You can remove the uniform fill from a shape by using the Fill.ApplyNoFill method. Applying fountain fills Fountain fills display a progression between two colors. A fountain fill is represented by the Fill.Fountain property as a FountainFill object, which specifies the various properties for the fountain fill: start color, end color, angle, blend type, and so on. The colors in a fountain fill are represented by a FountainColors collection. You can apply a fountain fill to a shape by using the Fill.ApplyFountainFill method. This method provides optional parameters for various fountain-fill settings, such as the midpoint and offset of the blend. The following VBA example creates a simple linear fountain fill, from red to yellow, at 30 degrees to the horizontal: Dim startCol As New Color, endCol As New Color startCol.RGBAssign 255, 0, 0 endCol.RGBAssign 255, 255, 0 ActiveShape.Fill.ApplyFountainFill startCol, endCol, cdrLinearFountainFill, 30 You can add a color to a fountain fill by using the FountainColors.Add method. Color positions are integer values in percent, where 0% is the start-color position and 100% is the end-color position. The following VBA example adds a green color to the fountain fill at a position about one-third (33%) of the way from the existing red color: Dim fFill As FountainFill Set fFill = ActiveShape.Fill.Fountain fFill.Colors.Add CreateRGBColor(0, 102, 0), 33 You can move a color in a fountain fill by using the FountainColor.Move method. The following VBA code moves the green color from the previous example to a position that is 60% of the way from the red (that is, more towards the yellow): ActiveShape.Fill.Fountain.Colors(1).Move 60 Understanding the Corel DESIGNER and CorelDRAW object models 135 You can use the FountainColors.Count property to determine the number of colors between the start color and end color of a fountain fill. (For the preceding example, this value is 1.) The first color in the collection is that start color, and its index number is 0; this color cannot be moved, but its color can be changed. The last color in the collection is the end color, and its index number is (Count + 1); this color cannot be moved, but its color can be changed. The following VBA code changes the end color from yellow to blue: Dim cols As FountainColors Set cols = ActiveShape.Fill.Fountain.Colors cols(cols.Count + 1).Color.RGBAssign 0, 0, 102 You can remove the fountain fill from a shape by using the Fill.ApplyNoFill method. Applying pattern fills Pattern fills display a series of repeating vector objects or bitmap images. A pattern fill is represented by the Fill.Pattern property as a PatternFill object, which specifies the various properties for the pattern fill: foreground color, background color, tile offset, and so on. The collection of available pattern fills is stored in the PatternCanvases collection. You can apply a pattern fill to a shape by using the Fill.ApplyPatternFill method. You can remove the pattern fill from a shape by using the Fill.ApplyNoFill method. Applying texture fills Texture fills are fractally generated and fill a shape with one image rather than a series of repeating images. A texture fill is represented by the Fill.Texture property as a TextureFill object, which specifies the various properties for the texture fill: origin, resolution, tile offset, and so on. The properties for a texture fill are stored in a TextureFillProperties collection. You can apply a texture fill to a shape by using the Fill.ApplyTextureFill method. You can remove the texture fill from a shape by using the Fill.ApplyNoFill method. Applying PostScript fills PostScript fills are texture fills that are designed by using the PostScript language. A PostScript fill is represented by the Fill.PostScript property as a PostScriptFill object, which specifies the various properties for the PostScript fill. You can apply a PostScript fill to a shape by using the Fill.ApplyPostScriptFill method. You can remove the PostScript fill from a shape by using the Fill.ApplyNoFill method. Applying hatch fills Hatch fills are composed of vector-based lines and can be used to clearly distinguish the materials or object relationships in a drawing. A hatch fill is represented by the Fill.Hatch property as a HatchFill object, which specifies the various properties for the hatch fill. Understanding the Corel DESIGNER and CorelDRAW object models 136 The collection of available hatch-fill patterns is stored in the HatchPatterns collection, and each document stores its own library of hatch-fill patterns in a HatchLibraries collection. You can apply a hatch fill to a shape by using the Fill.ApplyHatchFill method. You can remove the hatch fill from a shape by using the Fill.ApplyNoFill method. Applying outlines You can use the various properties and methods of the Outline class to define the outline of a shape. The Outline.Type property uses the following constants of the cdrOutlineType enumeration to record whether the specified shape has an outline: • cdrOutline — indicates that the shape has an outline • cdrNoOutline — indicates that the shape does not have an outline If a shape has no outline, setting its Outline.Type property to cdrOutline applies the document-default outline style. If a shape has an outline, setting its Outline.Type property to cdrNoOutline removes that outline. The Outline.Width property for an outline sets its width in document units. In the following VBA example, the outline of the selected shapes is set to 1 millimeter: ActiveDocument.Unit = cdrMillimeter ActiveSelection.Outline.Width = 1 If a shape does not have an outline, its Outline.Width value is 0. Changing this value applies an outline and automatically changes the value for the Outline.Type property from cdrNoOutline to cdrOutline. Similarly, if a shape has an outline, its Outline.Width value is greater than 0. Changing this value to 0 removes the outline and automatically changes the value for the Outline.Type property from cdrOutline to cdrNoOutline. The Outline.Color property for an outline defines its color, as in the following VBA example: ActiveSelection.Outline.Color.GrayAssign 0 ' Set to black Setting the color of an outline automatically sets the Outline.Type property of that outline to cdrOutline and applies the default outline width. The Outline.Style property for an outline specifies the dash settings of that outline. These dash settings are defined by the following properties of the OutlineStyle class: • DashCount — represents the number of pairs of dashes and gaps in an outline. This value ranges from 1 to 5. • DashLength — represents the length of each dash in an outline. This value is calculated as a multiple of the outline width, which is measured in document units. For example, if DashLength(1) is 5 and the outline is 0.2" wide, the length of the dash is 1"; however, if the width of the line is changed to 0.1", the length of the dash becomes 0.5". Understanding the Corel DESIGNER and CorelDRAW object models 137 • GapLength — represents the length ofeach gap in an outline. This value is calculated as a multiple of the outline width, which is measured in document units. • Index — represents the index number of a predefined outline style in the OutlineStyles collection for the application. The OutlineStyles collection is customizable, so the index number that is associated with each outline style in the collection may vary from user to user; however, the expression OutlineStyles.Item(0) always specifies a solid line. Outline objects have many other properties, including the following: • StartArrow and EndArrow — specify the arrowhead on each end of an open curve • LineCaps and LineJoin — respectively, specify the type of line caps (butt, round, or square) and line joins (bevel, miter, or round) • NibAngle and NibStretch — specify the shape of the nib used to draw the outline • BehindFill and ScaleWithShape — respectively, draw the outline behind the fill and scale the outline with the shape Outline objects also have methods, including the following: • ConvertToObject — converts the outline to an object • SetProperties — sets most of the available outline properties in a single call Working with color The Color class defines the fill colors and outline colors that you apply to shapes. This class provides a number of properties and methods for working with color. You can determine the color model of a color by accessing its Color.Type property, as in the following VBA example: Dim colType As cdrColorType colType = ActiveShape.Outline.Color.Type The Color.Type property is defined by the cdrColorType enumeration, which provides the following constants (among many others) for supported color models: • cdrColorCMYK — specifies the CMYK color model • cdrColorRGB — specifies the RGB color model • cdrColorGray — specifies the grayscale color model The color components for each supported color model are defined by additional properties of the Color class, as demostrated by the following VBA examples: • CMYK color model — is defined by the Color.CMYKCyan, Color.CMYKMagenta, Color.CMYKYellow, and Color.CMYKBlack properties • RGB color model — is defined by the Color.RGBRed, Color.RGBGreen, and Color.RGBBlue properties • grayscale color model — is defined by the Color.Gray property The range of values that is supported by a color component depends on the color model for that component. To create a color, you can use the automation keyword New, as in Dim col As New Color. Understanding the Corel DESIGNER and CorelDRAW object models 138 To assign a color model to a new color, you can use the desired ...Assign method (such as Color.CMYKAssign, Color.RGBAssign, or Color.GrayAssign). Each of these methods provides one parameter for each color component in its respective color model. For example, col.RGBAssign 0, 0, 102 assigns a deep-blue RGB color to the new color that was created in the previous tip. To use the application’s color-management settings to change the color model that is assigned to a color, you can use the desired ConvertTo... method (such as Color.ConvertToCMYK, Color.ConvertToRGB, or Color.ConvertToGray). For example, ActiveShape.Fill.UniformColor.ConvertToRGB converts the fill of the active shape to the RGB color model. You can copy the properties of one color to another color by using the Color.CopyAssign method, as in the following VBA example: Dim sh As Shape Set sh = ActiveShape sh.Outline.Color.CopyAssign sh.Fill.UniformColor The color “none” does not exist. To set a fill color or outline color to “none,” you must instead set the fill type or outline type to “none.” Applying effects to shapes The object model provides a number of methods for applying effects to shapes. For information on these methods, see the following subtopics: • “Applying blends” on page 139 • “Applying contours” on page 140 • “Applying customized effects” on page 140 • “Applying distortions” on page 140 • “Applying drop shadows” on page 141 • “Applying envelopes” on page 141 • “Applying extrusions” on page 141 • “Applying lenses” on page 141 • “Applying perspective” on page 141 Applying an effect returns an Effect object, which lets you access various properties and methods for the created effect. For example, you can use the Effect.Separate method to separate the shapes that are generated by an effect from the shape to which that effect is applied. In addition, you can use the Effect.Clear method to remove an effect from a shape. Applying blends The Shape.CreateBlend method creates a blend between the current shape and the shape that is specified as a parameter. This method provides optional parameters for various blend settings, such as the acceleration of the blend and the path along which the blend is created. Understanding the Corel DESIGNER and CorelDRAW object models 139 The following VBA code creates a basic ten-step blend: Dim sh As Shapes, eff As Effect Set sh = ActiveSelection.Shapes Set eff = sh(1).CreateBlend(sh(2), 10) In the preceding example, the number of shapes in the blend is twelve: the start and end shapes, plus the ten blend steps that are created. The Shape.CreateBlend method returns an Effect object, the Effect.Blend property for which you can use to modify the created blend. Applying contours The Shape.CreateContour method applies a contour to a shape. This method provides optional parameters for various contour settings, such as the colors and acceleration of the contour. The following VBA code creates a three-step contour at a five-millimeter spacing: Dim eff As Effect ActiveDocument.Unit = cdrMillimeter Set eff = ActiveShape.CreateContour(cdrContourOutside, 5, 3) The Shape.CreateContour method returns an Effect object, the Effect.Contour property for which you can use to modify the created contour. Applying customized effects The Shape.CreateCustomEffect method applies a customized effect to a shape. This method provides parameters for various effect settings. The Shape.CreateCustomEffect method returns an Effect object, the Effect.Custom property for which you can use to modify the created effect. Applying distortions The following methods apply a distortion to a shape: • Shape.CreatePushPullDistortion — applies a Push-and-pull distortion • Shape.CreateTwisterDistortion — applies a Twister distortion • Shape.CreateZipperDistortion — applies a Zipper distortion • Shape.CreateCustomDistortion — applies a customized distortion These methods provide parameters for various distortion settings. The distortion-creation methods return an Effect object, the Effect.Distortion property for which you can use to modify the created distortion. If you want, you can use event handlers to respond to events that are triggered by distorting a shape: • Document.ShapeDistort Understanding the Corel DESIGNER and CorelDRAW object models 140 Applying drop shadows The Shape.CreateDropShadow method applies a drop shadow to a shape. This method provides optional parameters for various drop-shadow settings, such as the feathering and offset of the drop shadow. The Shape.CreateDropShadow method returns an Effect object, the Effect.DropShadow property for which you can use to modify the created drop shadow. Applying envelopes The following methods apply an envelope to a shape: • Shape.CreateEnvelope — applies a basic envelope • Shape.CreateEnvelopeFromCurve — applies an envelope by using the specified curve as a template • Shape.CreateEnvelopeFromShape — applies an envelope by using the specified shape as a template These methods provide parameters for various envelope settings. The envelope-creation methods return an Effect object, the Effect.Envelope property for which you can use to modify the created envelope. Applying extrusions The Shape.CreateExtrude method applies an extrusion to a shape. This method provides optional parameters for various extrusion settings, such as the angle and color of the extrusion. The Shape.CreateExtrude method returns an Effect object, the Effect.Extrude property for which you can use to modify the created extrusion. Applying lenses The Shape.CreateLens method applies a lens to a shape. This method provides optional parameters for various lens settings, such as the color and magnitude of the lens. The Shape.CreateLens method returns an Effect object, the Effect.Lens property for which you can use to modify the created lens. Applying perspective The Shape.CreatePerspective method applies perspective to a shape. This method provides optional parameters for specifying horizontal and vertical vanishing points. The Shape.CreatePerspective method returns an Effect object, the Effect.Perspective property for which you can use to modify the created perspective effect. Projecting shapes Isometric projections are two-dimensional objects that are converted into apparent three-dimensional objects. In Corel DESIGNER, you can project a single shape by using the Shape.Project method, or you can project a range of shapes by using the ShapeRange.Project method. Understanding the Corel DESIGNER and CorelDRAW object models 141 Shapes in a range are projected parallel to each other, so they do not converge to a vanishing point. You can project shapes onto three isometric planes: • top • front (default) • right You can also originate the projection from a specified reference point: • top left • top middle • top right • middle left • center (default) • middle right • bottom left • bottom middle • bottom right Finally, you can apply a projection to a duplicate of the specified object or to the original object. The following VBA code sample illustrates how to create a projection: Sub MakeProjection() Dim shp1 As Shape, shp2 As Shape, shp3 As Shape Dim shpRng As ShapeRange 'Create a pair of rectangles and a circle. ActiveDocument.Unit = cdrMillimeter Set shp1 = ActiveLayer.CreateRectangle2(0, 0, 10, 20) Set shp2 = ActiveLayer.CreateRectangle2(50, 50, 20, 10) Set shp3 = ActiveLayer.CreateEllipse(10, 10, 20, 20) 'Add the rectangles to a ShapeRange. Set shpRng = ActiveLayer.FindShapes(Type:=cdrRectangleShape) 'Project the shapes onto the top isometric plane, 'using the upper-right corner of the ShapeRange bounding box 'as the anchor point. Modify the original object. shpRng.Project cdrProjectTop, cdrTopRight 'Project a duplicate of the circle onto the right isometric plane, 'using the default reference point. shp3.Project Plane:=cdrProjectRight, ApplyToDuplicate:=True End Sub Understanding the Corel DESIGNER and CorelDRAW object models 142 Searching for shapes In your macros, you can include queries that search for shapes that have specific shape properties, fill properties, outline properties, or color properties. To do this, you use Corel Query Language (CQL) in conjunction with one of the following methods: • Shape.Evaluate — returns the result of a given expression that evaluates the properties of the current shape • Shapes.FindShape — returns a single shape that has the specified properties • Shapes.FindShapes — returns, as a shape range, all shapes that have the specified properties You can specify the shape properties for which to search. For example, the expression ActiveShape.Evaluate("@name") searches searches the Name property of all selected shapes. Consider the following VBA code sample, in which the Type property and the Width property are used to select all rectangles that are wider than two inches: ActivePage.Shapes.FindShapes(Query := "@type = 'rectangle' and _ @width > {2 in}").CreateSelection For comprehensive information on using CQL, see “Including queries in macros” in the Macros Help file for the application. Deleting shapes If you want, you can use event handlers to respond to events that are triggered by deleting a shape: • Document.ShapeDelete Working with import filters and export filters As previously discussed, methods are available for importing files (see “Importing files into layers” on page 102) and exporting files (see “Exporting files from documents” on page 88). These file-import and file-export methods can also be used for performing batch conversions or modifying file repositories. The wide selection of supported file formats is due to the vast number of filters that are available to the application. Each filter lets you work with the files from another graphics application. To learn more about working with these filters, see the following topics: • “Working with import filters” on page 144 • “Working with export filters” on page 146 Understanding the Corel DESIGNER and CorelDRAW object models 143 Working with import filters To ensure the portability of a file-import script, you must use the default ImportFilter object (rather than the filter-specific object DSFImport), as in the following VBA example: Sub OpenRectangle() Dim FilterObject As ImportFilter 'Initialize FilterObject Set FilterObject = ActiveLayer.ImportEx("C:\devo\rect.dsf", _ cdrDSF) 'Set the advanced features of the filter FilterObject.DefaultLinestyle = 1 'Dashed FilterObject.DeleteInvisibleObjects = True 'Invoke the filter FilterObject.Finish End Sub For best results, use the filter-specific object DSFImport only to learn the specific interfaces that are supported by a filter. For example, the following screenshot demonstrates that the ImportFilter object exposes only generic interfaces in Microsoft® IntelliSense® because the ImportFilter interface is generic (and not filter-specific). The ImportFilter object does not contain the DefaultLinestyle and DeleteInvisibleObjects properties; however, you can still set these properties in the ImportFilter interface if they are supported by the specified import filter. As previously discussed, using the ImportFilter object (rather than the filter-specific object DSFImport) ensures that a file-import script can be used on any other workstation running the same version of the application. To reference the properties, methods, and enumerations for a specific filter, locate that filter in the Object Browser. For example, the following screenshot demonstrates that the line-style dsfDashed2 can be specified by assigning a value of 7 to the DefaultLinestyle property. Understanding the Corel DESIGNER and CorelDRAW object models 144 To access the object model for a filter, click Tools ` References from within the Macro Editor. In the References dialog box that appears, click Browse, and navigate to the Filters folder of the installed software. Select the dynamic-link library (DLL) file for the desired filter, and then click OK. When the References dialog box reappears, enable the checkbox that corresponds to the desired filter, and then click OK. You can now access the object model for the filter, as in the following VBA example: Sub OpenRectangleDSF() Dim FilterObject As DSFImport Dim Style As DsfLinestyle 'Initialize FilterObject Set FilterObject = ActiveLayer.ImportEx("C:\devo\rect.dsf", _ cdrDSF) 'Set the advanced features of the filter Style = dsfDashed FilterObject.DefaultLinestyle = Style FilterObject.DeleteInvisibleObjects = True 'Invoke the filter FilterObject.Finish End Sub Working with an import filter is made much easier by having the script access the object model for that filter; however, as discussed, this technique reduces the portability of the script. When used at another workstation, the script must first be updated with the correct location of the DLL file for the filter. Understanding the Corel DESIGNER and CorelDRAW object models 145 Working with export filters The following VBA example shows how to save a document as an AutoCAD DXF file by using an export filter: Sub SaveRectangleDXF() Dim FilterObject As DXFExport Dim BitmapType As DxfBitmapType Dim TextAsCurves As Boolean Dim Units As DxfUnits Dim Version As DxfVersion 'Initialize FilterObject Set FilterObject = ActiveDocument.ExportEx("C:\devo\rect.dxf", _ cdrDXF) 'Set the advanced features of the filter BitmapType = dxfBitmapGIF FilterObject.BitmapType = BitmapType Units = dxfInches FilterObject.Units = Units TextAsCurves = False FilterObject.TextAsCurves = TextAsCurves Version = dxfVersion2000 FilterObject.Version = Version 'Invoke the filter FilterObject.Finish End Sub In the preceding example, a call is made to ActiveDocument.ExportEx method, and the interface for the export filter (DXFExport) is invoked. However, you can use the generic export interface (ExportFilter): Sub SaveRectangle() Dim FilterObject As ExportFilter 'Initialize FilterObject Set FilterObject = ActiveDocument.ExportEx("C:\devo\rect.dxf", cdrDXF) 'Set the advanced features of the filter FilterObject.BitmapType = 1 'GIF FilterObject.Units = 0 'Inches FilterObject.TextAsCurves = False FilterObject.Version = 1 'AutoCAD 2000 'Invoke the filter FilterObject.Finish End Sub Understanding the Corel DESIGNER and CorelDRAW object models 146 The following VBA example demonstrates how to invoke the Export dialog box: Sub ShowExportDialog() Dim FilterObject As ExportFilter Dim vntReturn As Variant 'Initialize FilterObject Set FilterObject = ActiveDocument.ExportEx("C:\devo\rect.dxf", cdrDXF) 'If FilterObject supports a dialog, invoke it If (FilterObject.HasDialog = True) Then vntReturn = FilterObject.ShowDialog 'Verify that the user clicked "OK" and not "Cancel" If (vntReturn = True) Then 'Invoke the filter FilterObject.Finish End If End If End Sub The preceding example requires you to check the return value of the dialog box, and to invoke the Finish method for when the user clicks OK. Understanding the Corel DESIGNER and CorelDRAW object models 147 Glossary argument See “parameter.” array A set of sequentially indexed objects of the same data type (or “array elements”) Each array element has the same data type (although elements can have different values), and the entire array is stored contiguously in memory (with no gaps between elements). For example, you could have an array of integers or an array of characters or an array of anything that has a defined data type. By default, array indexes are zero-based. Arrays can have more than one dimension. A one-dimensional array is called a “vector,” while a two-dimensional array is called a “matrix.” automation The process of recording or scripting a macro class The definition of each property, method, and event that applies to a type of object in the application class module A type of module that contains the definition of an object-oriented Visual Basic class, including the definitions of the properties and methods for that class collection A group of objects that have similar characteristics and similar actions but that are uniquely identified by index names or index numbers Collections are always plural.

An event is triggered by an action — such as a click, key press, or system timer — and you can write code that causes an object to respond to that event. event-driven programming A style of programming, unlike traditional procedural programming (in which the program starts at line 1 and executes line by line), that executes code in response to events Visual Basic for Applications is an event-driven programming language. Most of the code you create is written to respond to an event. Compare with “object-oriented programming.” event handler A subroutine that is programmed to cause the application to respond to a specific event form A type of module that is used for customized dialog boxes and user interfaces, and that includes the code to control them function A procedure that performs a given task in a macro and that can be used to return a value A function procedure begins with a Function statement and ends with an End Function statement. In VBA and VSTA, functions do not need to be declared before being used, nor before being defined. gap A space between dashes in an outline style global value A value that applies to a given project in its entirety GMS file Also called a “project file” (and short for “Global Macro Storage file”), the location to which the Macro Editor stores all modules for a project Glossary 149 index number A reference to an object in a collection that contains more than one object An index number is used to identify each object in a collection. The index number can range from 1 to the number of available objects within the collection. macro A recorded or scripted set of tasks that can be repeatedly invoked within an application A macro is a symbol, name, or key that represents a list of commands. method An operation that an object can have performed on itself modal dialog box A dialog box thatlocks the application and must be acted upon (that is, either submitted or cancelled) before the macro can be resumed Most built-in dialog boxes that can be controlled by automation coding are modal. modeless dialog box A dialog box that does not lock the application and can be left open while the user continues working in the application Modeless dialog boxes behave like dockers. module A container that is used by a GMS file for storing project components Generic modules are used for general code and for macros. Other types of modules include forms and class modules. object When referring to an object model, an instance of a class object model A high-level structure of the relationship between the parent objects and child objects in an application For example, the Application object represents the beginning of the object hierarchy. From the Application object, you can “drill down” and navigate through the object model until you find the desired object. To reference an object with Visual Basic code, you separate each level of the object hierarchy with the dot operator ( . ). object-oriented programming A style of programming that places emphasis on creating and using objects Compare with “event-driven programming.” parameter Synonymous with “argument,” a value that is passed to a routine and that defines a characteristic of an object in the Visual Basic programming environment Glossary 150 Parameters are attributes that appear after a recorded command in the Recorder docker. For example, dialogbox options are not recorded as separate commands in the Recorder docker; they are recorded as attributes of the command that initially invoked the dialog box. passing by reference The act of passing an argument to a function or subroutine by using a reference to the original By default, function parameters and subroutine parameters are passed by reference. To explicity indicate that you want to pass an argument by reference, prefix the argument with ByRef. passing by value The act of passing an argument to a function or subroutine by using a copy of the original To explicity indicate that you want to pass an argument by value, prefix the argument with ByVal. property A characteristic of a class Properties can be returned or set. In addition, properties can be designated as read-only (to indicate that they are fixed by the design of the class). range A series of similar objects scope The visibility of a data type, procedure, or object shortcut object A syntactic replacement for the longhand version of an object String A data type consisting of a sequence of contiguous characters that represent the characters themselves rather than their numeric values A string can include letters, numbers, spaces, and punctuation. The String data type can store fixed-length strings ranging in length from 0 to approximately 63K characters and dynamic strings ranging in length from 0 to approximately 2 billion characters. The dollar sign ( $ ) type-declaration character represents a string in Visual Basic. sub See “subroutine.” subroutine Sometimes called a “sub,” a procedure that performs a given task in a macro but cannot be used to return a value A subroutine procedure begins with a Sub statement and ends with an End Sub statement. In VBA and VSTA, subroutines do not need to be declared before being used, nor before being defined. variable An item that can be created (or “declared”) for the purposes of storing data Glossary 151 The built-in data types are Boolean, Double, Integer, Long, Single, String, Variant, and several other lessused types including Date, Decimal, and Object. If a variable is not declared before being used, the compiler interprets it as a Variant. Variant The data type for all variables that are not declared as another type, such as Dim, Private, Public, or Static The Variant data type has no type-declaration character. VBA A built-in programming language that can automate repetitive functions and create intelligent solutions in a software application VBA is a subset of the Microsoft Visual Basic (VB) object-driven programming environment, but it is considered “for applications” because it is most often integrated into another application to customize the functionality of that application. Visual Basic for Applications See “VBA.” Visual Studio Tools for Applications See “VSTA.” VSTA The successor to VBA VSTA is based on Microsoft Visual Studio 2008. The integrated development environment (IDE) for VSTA can be used to support two additional programming languages (Visual Basic .NET and C#) and to take advantage of the .NET framework natively.
