////////////////////////////////////////////////////////////////////////////////////////////////////
// This example was designed for using in Microsoft Visual C# from 
// Microsoft Visual Studio 2003 or above.
//
// 1. Adobe Acrobat 6.0 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 5.0 or above should be installed, too.
//
// 3. Add references to "Adobe Acrobat X.0 Type Library" and "UDC 5.0 Type Library" using 
//    the Project | Add Reference menu > COM tab.
//    The version number in the type library name may be different depending on Acrobat's version 
//    installed on your computer.
