Converting AutoCAD Drawings to PDF


//////////////////////////////////////////////////////////////////
// This example was designed for using in Microsoft Visual C++ from 
// Microsoft Visual Studio 2003 or above.
//
// 1. Autodesk AutoCAD 2000 or above should be installed and activated on your PC.
//    Autodesk AutoCAD LT 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 AutoCAD libraries for 32-bit version of Windows.
// For 64-bit version please change "C:\\Program Files\\" to
// "C:\\Program Files (x86)\\" in all pathes.
