Overview
Foxit Reader 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 Reader 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 3.0 incorporates many advanced PDF features. It supports annotation and allows
users to fill out, import or export PDF form data. Version 3.0 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 3.0 (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 3.0 version would
be best for your application. You can purchase either the standard or professional version
online. For the Form Module, which is a new module in Version 3.0, 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.
Foxit Reader 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 Reader SDK AcitveX 3.0 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 3.0 Professional. If you would like to use this module, please contact us at
sales@foxitsoftware.com.

Programming Guide

UNLOCK Code: If you have purchased Foxit Reader 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：DB2189DF-ABF4-445A-A4E5-BF32F2CEA4D9
GUID for professional version：358327D8-B2C5-402f-B1F5-DD89FAA68B26

Programming Guide

Tutorials
The Foxit Reader SDK ActiveX control comes with a single OCX file. To install it, please
use command "regsvr32 foxitreader_ax.ocx". You may need to specify the proper path if
foxitreader_ax.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
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");

Programming Guide

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

Programming Guide

[None]
Return value:
If next view exists, then it will return true. Otherwise, it will return false.
Comment:
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.

GoForwardStack
Jump to the next view.
Prototype:
Void
GoForwardStack ();
Parameters:

Programming Guide

[None]
Return value:
[None]

ExistBackwardStack
Detect the existence of previous view.
Prototype:
BOOL ExistBackwardStack ();
Parameters:
[None]
Return value:
If previous view exists, then it will return true. Otherwise, it will return false.

GoBackwardStack
Jump to previous view,
Prototype:
void
GoBackwardStack ();
Parameters:

SetViewRect
Display a rectangle of current PDF page.
Prototype:
Void SetViewRect (float Left, float Top, float Width, float Height);
Parameters:
Left
The horizontal coordinate of the top left corner.
Top
The vertical coordinate of the top left corner.
Width
The width of the rectangle.
Height
The height of the rectangle.
Return value:
[None]
Comment:
This function will show a rectangle of current PDF page. The coordinate here is PDF
coordinate, not device coordinate. And the unit is PDF point. The function will keep the
position and size of ActiveX window unchanged and adjust the position and the zoom
factor of current PDF page so that the designate rectangle of current PDF page will be
shown fully inside the ActiveX window. A typical application is: the end user use the mouse
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.

ConvertClientCoordToPageCoord

Programming Guide

Converts a point in ActiveX control window's client co-ordinates into PDF page coordinate.
Prototype:
BOOL
ConvertClientCoordToPageCoord (long nClientX, long nClientY,

pnPageIndex For returning page number in which the given point falls on
pPageX
For returning x coordinate of the point inside the PDF page
(in PDF co-ordinate system)
pPageY
For returning y coordinate of the point inside the PDF page
(in PDF co-ordinate system)
Return value:
Return value indicates whether the conversion is successful. The client area contains the
PDF page being shown as well as some grey background. If the point is located in the grey
background, the conversion will fail.

ConvertPageCoordToClientCoord
Converts PDF page coordinates to the coordinates inside ActiveX control window's client
area.
Prototype:
BOOL ConvertPageCoordToClientCoord (long nPageIndex, float dPageX, float dPageY,
long* pnClientX, long* pnClientY);
Parameters:
nPageIndex page number
dPageX
X coordinate inside the PDF page (in PDF co-ordinate system)
dPageY
Y coordinate inside the PDF page (in PDF co-ordinate system)
pnClientX
For returning X coordinate in the ActiveX control window's client area. A
negative result indicates that the point is outside the ActiveX control
window's client area.
pnClientY
For returning Y coordinate in the ActiveX control window's client area. A
negative result indicates that the point is outside the ActiveX control
window's client area.
Return value:
Return value indicates whether the conversion is successful. If the document is not opened
properly or if the page number is incorrect, then the return value will be false. Otherwise,
the return value will be true.
