Overview
Foxit PDF SDK ActiveX is a visual programming component that offers PDF displaying capability with lowest
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.
The ActiveX version is much easier to use and has much more 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.
From version 5.0, ActiveX incorporates Signature module and many advanced PDF features, such as
asynchronous feature. Signature module allows developers to enable their applications to digitally sign PDF
documents using third-party digital certificates located in the Windows system certificate store. It also
supports digital signature verification (which authenticates the source and verifies the integrity of content of
digitally signed PDF documents), signature print control and more.
From version 5.2, ActiveX provides native 64-bit support.
Foxit offers two versions of ActiveX – standard version and professional version, 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: page organization, setting password and permission, printing pop-up annotations,
importing/exporting annotation data, importing/exporting form data, running JavaScript, converting PDF to
text, etc.
Based on your requirements you are able to pick and choose which ActiveX version and which ActiveX
module would be best for your application. Please Scaling
that the three modules can only be added to Professional version as the add-ons. Please contact
sales@foxitsoftware.com for license details.
In this developer’s guide,
All the functions marked with an asterisk (*) are available only in the professional version
All the functions marked with a hash sign (#) are available only in the Form Module
All the functions marked with a caret (^) are available only in the Annotation Module
All the functions marked with an ampersand (&) are only available in Signature Module.
Foxit PDF SDK ActiveX runs on Windows XP 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.
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 functions once inside your program before you call ANY other
functions of the ActiveX. You don’t need to call this function if you just want to evaluate the ActiveX.
GUID for standard version: 0F6C092B-6E4C-4976-B386-27A9FD9E96A1
GUID for professional version: F53B7748-643C-4A78-8DBC-01A4855D1A10

4) Open a PDF document
Now you can run this basic program and open PDF documents by click the yellow folder
5) How to call functions
To call other functions, they should be used by following axFoxitPDFSDK1.
Programming Guide
24 / 206
In this example, these two lines are to open fw9.pdf on your desktop, and then rotate the first page
to right by 90 degree.
6) How to create your own projects
You can see more options in this list and create your own project from there.
Getting Started: Basic PDF Functions
The following part contains references to the AX_Pro_Demo. To get a full understanding of how the functions
works, the user should set breakpoints and step through the code. File names and line numbers for specific
function calls are provided.
1) Unlocking the SDK
The evaluation version of the ActiveX SDK will apply a watermark across any rendered PDF page.
Programming Guide
25 / 206
Customers who pay for the SDK will receive a license key to remove the watermark.
The license key will contain a license id and an unlock code that you will pass in as parameters to
the UnLockActiveX function. There is an example of this in AX_Pro_DemoDlg.cpp.
BOOL CAX_Pro_DemoDlg::OnInitDialog()
{
CDialog::OnInitDialog();
// code
m_AX.UnLockActiveX(_T("Licence_ID"),_T("Unlock_code"));
// code
}
2) Opening a PDF File
Call the OpenFile function to open a PDF file for viewing. There is a working example in
AX_Pro_DemoDlg.cpp.
void CAX_Pro_DemoDlg::OnFileOpen()
{
//code
m_AX.OpenFile(fdg.GetPathName() ,NULL );
Programming Guide
26 / 206
// code
}
The user can trigger the OnFileOpen event by going to File > Open > browse to a PDF file > click on
Open or by using the file open folder icon.
3) Go to a specific page
Use the GoToPage function to navigate directly to the page number specified as the parameter.
Page indexing is zero based. So call GoToPage(0) to get to the first page.
The AX_Pro_Demo has arrows for navigating to the first, previous, next, and last page of a
multipage document. To see these functions in action, run the demo and open a multiple page PDF.
In AX_Pro_DemoDlg.cpp, you will see the corresponding events that are triggered when the arrow
buttons for navigating pages are pressed. You will see the GoToPage function is called with the
appropriate index value.
void CAX_Pro_DemoDlg::OnFirstPage()
{
m_AX.GoToPage(0);
}
void CAX_Pro_DemoDlg::OnLastPage()
{
int count = m_AX.GetPageCount();
m_AX.GoToPage(count-1);
}
Programming Guide
27 / 206
void CAX_Pro_DemoDlg::OnNextPage()
{ int count = m_AX.GetPageCount();
int current = m_AX.GetCurPage();
if(current+1 <= count-1)
m_AX.GoToPage(current+1);
}
void CAX_Pro_DemoDlg::OnPrevPage()
{
int count = m_AX.GetPageCount();
int current = m_AX.GetCurPage();
if(current-1 >= 0)
m_AX.GoToPage(current-1);
}
4) Zoom in and out of a page
Call SetZoomLevel to zoom in and out of the PDF page. The AX_Pro_Demo has menu buttons for
zoom in, zoom out, actual size, fit page, and fit width. All of these buttons trigger events that call
SetZoomLevel.
void CAX_Pro_DemoDlg::OnZoomIn()
{
Programming Guide
28 / 206
zoomfactor = m_AX.GetZoomLevel();
if(zoomfactor + 10 == 6400)
zoomfactor = 6400;
else
zoomfactor = zoomfactor + 10;
m_AX.SetZoomLevel( zoomfactor );
}
void CAX_Pro_DemoDlg::OnZoomOut()
{
zoomfactor = m_AX.GetZoomLevel();
if(zoomfactor - 10 > 0)
zoomfactor = zoomfactor - 10;
m_AX.SetZoomLevel( zoomfactor );
}
void CAX_Pro_DemoDlg::OnActualSize()
{
m_AX.SetZoomLevel(0);
}
void CAX_Pro_DemoDlg::OnFitPage()
{
m_AX.SetZoomLevel(1);
}
Programming Guide
29 / 206
void CAX_Pro_DemoDlg::OnFitWidth()
{
m_AX.SetZoomLevel(2);
}
5) Rotate a Page
Call SetRotate to rotate the PDF page. The AX_Pro_Demo has menu buttons for rotate right and
rotate left. These buttons trigger events that call SetRotate.
void CAX_Pro_DemoDlg::OnRotateRight()
{
if(rotatefactor == 3)
rotatefactor = 0;
else
rotatefactor++;
m_AX.SetRotate(rotatefactor);
}
void CAX_Pro_DemoDlg::OnRotateLeft()
{
if(rotatefactor == 0) rotatefactor=3;
else rotatefactor--;
m_AX.SetRotate( rotatefactor );
}
6) Print a PDF document
Call PrintWithDialog to bring up the print dialog page. On that page you can manually adjust printer
settings. Using the ActiveX SDK you can also programmatically set printer settings. Clicking on the
Programming Guide
30 / 206
printer icon.
or going to File > Print will trigger the OnFilePrint() event that calls the PrintWithDialog function to
bring up the print dialog settings.
void CAX_Pro_DemoDlg::OnFilePrint()
{
CPDFPrinter printer = m_AX.GetPrinter();
if (!printer)
{
return;
}
Programming Guide
31 / 206
//printer.SetPrinterName( "foxit PDF" );
printer.SetPrinterRangeMode( 3 );
printer.SetPrinterRangeFrom( 2 );
printer.SetPrinterRangeTo( 3 );
printer.SetPaperSize( 8 );
printer.SetNumOfCopies( 2 );
printer.PrintWithDialog();
}
7) Hide/Show UI elements
The ActiveX SDK provides functions for modifying the user interface. For example, the ShowToolBar()
function takes a boolean parameter. This is what the user interface looks like when
ShowToolBar(FALSE) is called by the application code.
ShowToolBar(TRUE) adds the toolbar to the user interface.
In AX_Pro_DemoDlg.cpp, the ShowToolBar function is called with FALSE as the default setting. As an
exercise, the user can change m_ToolState to be TRUE to enable the toolbar when the demo is run.
BOOL CAX_Pro_DemoDlg::OnInitDialog()
{
// code
m_ToolState = FALSE;
// code
Programming Guide
32 / 206
m_AX.ShowToolBar( m_ToolState );
// code
}
8) Iterate the tree outline of the PDF document
If the user wants to build a table of contents for a PDF document, they can use the
GetOutlineFirstChild() and GetOutlineNextSibling() functions to iterate through the outline tree of
the PDF. Here’s an example of a TOC using the AX_Pro_Demo.
In AX_Pro_DemoDlg.cpp in the CAX_Pro_DemoDlg::OnFileOpen() function there is code that shows
how the TOC is generated when the file is first open in the demo. To get a closer understanding, it is
recommended that the developer set a breakpoint at the beginning of this function and step
through. See where GetOutlineFirstChild and GetOutlineNextSibling are called.
void CAX_Pro_DemoDlg::OnFileOpen()
Programming Guide
33 / 206
{
// code
CPDFOutline outline;
outline = m_AX.GetOutlineFirstChild( outline.m_lpDispatch );
if (outline != NULL)
{
outline = NULL;
ProcOutline(outline,NULL);
}
OnMENUITEMexpandtree();
if (m_outlinetree.GetCount()>0)
{
ShowBookMark();
m_bhidebookmark = TRUE;
}
else
{
HideBookMark();
m_bhidebookmark = FALSE;
}
}
9) Search
The AX_Pro_Demo has a search icon in the toolbar that allows a user to search through a PDF for
specific words or phrases.
Programming Guide
34 / 206
This Find dialog box appears when the icon is clicked on,
The FindFirstEx() function finds the first occurrence of the string in the PDF document. The
parameters are the search string, a boolean to indicate if the user wants to match case, a Boolean
to indicate if the user wants to match the entire word. In FindDlg.cpp in the CFindDlg::OnOK()
function there is an working example of FindFirstEx() and FindNext().
void CFindDlg::OnOK()
{
UpdateData(true);
If (TRUE == m_bFirst)
{
// code to initialize the var parameter
m_pAX->FindFirstEx(var, m_check1, m_check2);
// code
}
else
//FindNext(BOOL) TRUE:down search, FALSE:up search
m_pAX->FindNext(TRUE);
}
