// To use: You must #include <afxole.h> in your stdafx.h.
//         You must also initialize/uninitialize COM.  One way to do this is
//         in your derived CWinApp::InitInstance(), add the following line:
//
//          ::CoInitialize(NULL);
//
//         And in your derived CWinApp::ExitInstance(), add the following line:
//
//          ::CoUnitialize();
