Programming Guide

Overview
Foxit PDF SDK ActiveX is a visual programming component that offers PDF displaying
capability with minimal resource demand and redistribution size. It can be easily
integrated into a wide range of applications.
Foxit PDF SDK ActiveX uses the same parsing and rendering engine as Foxit Reader.
Therefore it can display PDF files with the same high quality and fast speed as Foxit
Reader.
Compared to the DLL version of Foxit SDK, the ActiveX version is much easier to use and
has much more rich features built inside. A programmer can simply drag and drop the
component into their application and instantly add PDF displaying functionality. In addition,
the ActiveX allows users to navigate, zoom, rotate, scroll and print out PDF documents.
Version 4.0 incorporates Annotation Module and many advanced PDF features. It enables
you to build your own annotations and allows users to fill out, import or export PDF form
data. Version 4.0 also introduces more functions and events, giving programmers flexible
control over the component and more access to the PDF documents.
Foxit offers two versions of ActiveX 4.0 (standard and professional), which are provided
with different GUID numbers that allows you to register both versions onto the same
computer and access them with their own GUID. Compared with the professional version,
the standard version doesn’t include the following features: creating/editing annotation,
importing/exporting form data, running JavaScript, converting PDF to text, etc. Based on
your requirement needs you are able to pick and choose which ActiveX 4.0 version would
be best for your application. You can purchase either the standard or professional version
online. For the Form and Annotation Module, please contact sales@foxitsoftware.com for
licensing details. In this developer’s guide, all the properties and functions marked with an
asterisk (*) are available only in the professional version, all the properties and functions
marked with an asterisk (#) are available only in the Form Module and all the properties
and functions marked with an asterisk (^) are available only in the Annotation Module.
Foxit PDF SDK ActiveX runs on Windows 95/NT or later. This is a standalone component
and does not require any extra PDF software installed. Please note a user might need to
have administrator rights to register the ActiveX under Windows successfully.
There are several complete demo programs written in different languages, including
Visual Basic, Visual C++, Delphi, showing how to use the properties and methods of the
ActiveX. To download these methods please visit www.foxitsoftware.com.
Based on the professional version, Foxit PDF SDK AcitveX 4.0 adds many new interfaces
to support PDF Form Fields, which will allow users to add, delete, import or export, form
data in their PDF documents. The Form Module is licensed separately from ActiveX 4.0
Professional. If you would like to use this module, please contact us at

UNLOCK Code: If you have purchased Foxit PDF SDK ActiveX and received the full
version of the ActiveX and the unlock code, you should call UnLockActiveX or
UnLockActiveXEx functions once inside your program before you call ANY other functions
of the ActiveX. This function is described in the Reference section. You don’t need to call
this function if you just want to evaluate the ActiveX.
GUID for standard version：360BA9D0-6B2C-4DE1-A500-0D29AD6F5C2F
GUID for professional version：DDFACF72-E3B5-4A0B-A71F-F39678A34812

Programming Guide

Tutorials
The Foxit SDK ActiveX control comes with a single OCX file. To install it, please use
command "regsvr32 OCX name". You may need to specify the proper path if OCX is not
stored in current directory.
The ActiveX control handles user interface for you. It also supplies multiple properties and
methods so that your application is able to control the ActiveX.
The following is a example, suppose we had already created an ActiveX control called
FoxitReaderSDK.

1) Open a PDF File
We will open a PDF document named “testdoc.pdf”
// NOTE: If you are evaluating ActiveX, you don’t need to unlock it,
// then evaluation marks will be shown on all PDF pages.
// For paid customers, please unlock the ActiveX first.
FoxitReaderSDK.UnLockActiveX(“license_id”,”unlock_code”);
FoxitReaderSDK.OpenFile(“testdoc.pdf”,””);

2) Go to a specific page
We will go to the third page of the document
FoxitReaderSDK.GoToPage(2). //The index of first page is 0.

3) Zoom a page
If you want to show a PDF page with its original size, you can use the following code
in VC:
FoxitReaderSDK.SetZoomLevel(0);
Or
FoxitReaderSDK. SetZoomLevel(100);
If you want to set the zoom factor to 200%, use the following code:
FoxitReaderSDK. SetZoomLevel(200);
For more information, see Function Reference section of this guide.

4) Rotate a page
A PDF page can be displayed in four directions: upright, rotated 90 degree, rotated
180 degree, or rotated 270 degree. To display it in different direction, you only need to
call “SetRotate” () to change the Rotate property.
If you want to rotate the page (90 degrees) clockwise, you can use the following code
in VC:
FoxitReaderSDK. SetRotate(1);

Programming Guide

5) Print a PDF document
What you need to do is call “PrintWithDialog” method, a print dialog will pop up
and you will be able to specify parameters and then print out the PDF document. If
you want to print without popping up a dialog, you need to use the PDFPrinter
interface.

6) Hide or show UI elements
You can call “ShowToolBar” to show or hide the toolbar. Likewise, you may call
“ShowBookmark” to show or hide the bookmark panel and call “ShowStatusBar” to
show or hide the status bar. If you prefer to build your own toolbar, you may hide the
built-in ActiveX toolbar and then create your own outside the ActiveX.

7) Iterate the whole outline tree
You can call “GetOutlineFirstChild” or “GetOutlineNextSibling” to iterate the
whole outline tree, allowing you to view the outline information from PDFOutline
Interface.

8) Search a PDF document
You can call “FindFirst” to find the first instance of the given text in the whole
document. If no occurrence is found, then the function returns 0. If an occurrence is
found, the function returns a nonzero value and the occurrence will be highlighted.
Select “FindNext” again to search for the next occurrence.
If you want to search for text inside PDF files without opening and displaying
them, you may use the “FindFileFirst” or “FindFileNext”.

9) *Annotations tools
End users can draw lines, circles and other shapes on a PDF document by using
different markup tools. Your application may also change “CurrentTool” property
programmatically, for example, to the “Line Tool”.

10) #Form Application
In version 3.0, Foxit ActiveX provides an interface for PDF forms. By calling
“GetCurrentForm”, you can obtain the IForm interface pointer for the current PDF
document. Then you can use properties and methods in IPDFForm and
IPDFFormField interface classes to perform actions to PDF forms. The following code
shows how to add a form button in a PDF page:
CPDFformField button1 =
form1.AddField("button1","button",m_nCurPage,0,0,55,30);
button1.SetButtonCaption("N","Normal");
button1.SetButtonCaption("R","Rollover");
button1.SetButtonCaption("D","Down");
button1.SetBehavior("push"); // push;Invert; None; Outline;
button1.SetTooltip("reset all form");
button1.SetTextFont("Courier");
12

Programming Guide

button1.SetTextSize(15);
button1.SetJavaScriptAction("down","app.alert(\"Mouse Down!\")");

11）^Annotation Application
In version 4.0, Foxit ActiveX provides some interfaces to operate Annotation objects.
You can build your own annotations with these interfaces.

Programming Guide

Quite often, when a user navigates within a PDF file, he would like to go back to a previous
reading point. View is a concept that defines certain reading point or displaying status.
Certain user actions will create new views. For example, if a user turns to a new page, and
then zoom in the page, these two actions will create two new views. A program may call
this group of methods to allow user to jump among different views conveniently.

to click and drag a rectangle and then release the mouse, the program will call
ConvertClientCoodToPageCood to convert the mouse coordinates into PDF coordinates
and then call SetViewRect to display the specified area in full view.
