//////////////////////////////////////////////////////////////////
// This example was designed for using in Microsoft Visual C++ from 
// Microsoft Visual Studio 2003 or above.
//
// 1. Adobe Acrobat Writer 4.0 or above should be installed and activated on your PC.
//    Adobe Acrobat Reader does not have COM interface and cannot be used as COM-server!
//
// 2. Universal Document Converter 5.2 or above should be installed, too.
//
// 3. You must initialize the COM before you call any COM method.
// Please insert "::CoInitialize(0);" in your application initialization
// and "::CoUninitialize();" before closing it.
//
// 4. Import Acrobat libraries for 32-bit version of Windows.
// For 64-bit version please change "C:\\Program Files\\" to
// "C:\\Program Files (x86)\\" in all pathes.
#pragma message("Import Acrobat API")
// Acrobat 4.0 -> "C:\\Program Files\\Adobe\\Acrobat 4.0\\Acrobat\\acrobat.tlb"
// Acrobat 5.0 -> "C:\\Program Files\\Adobe\\Acrobat 5.0\\Acrobat\\acrobat.tlb"
