The example below shows how to use the PDFCreator control as a library in an MFC console application. The file Win32ConsoleApp.cpp is the only file (in addition to stdafx.cpp) that is produced by the Visual Studio wizard.
// Win32ConsoleApp.cpp : Defines the entry point for the console
// application.
// This sample demonstrates how we can use instantiate a
// PDFCreactiveX COM object and use its IPDFCreactiveX.
#include "stdafx.h"
// 1- Register the ActiveX COM control or class using ' regsvr32.exe "C:\My Installation Path\PDFCreactiveX.dll"'
// 2- Add a #import directive to .cpp or .h file where you want to use the control or to
// the stdafx.h file where it will be accessible to all files in the project that use the precompiled header
// raw_interfaces_only
#import "C:\Program Files\Amyuni PDF Suite\PDFCreactiveX.dll" no_namespace
// The line above will open the type library that is embedded as a resource inside the PDFCreactiveX.dll and after it reads this type library, it will generate two C++ files with the .tlh and .tli extenstions in the temp folder of the project. These two files will be included verbatim automatically by the preprocessor. The pdfcreactivex.tlh file will contain the GUIDs of the COM classes and COM interfaces that are found in the type library. It will also create smart pointer wrappers for the interfaces that we can use directly.
