//	Note! 
// 
//		If this DLL is dynamically linked against the MFC 
//		DLLs, any functions exported from this DLL which 
//		call into MFC must have the AFX_MANAGE_STATE macro 
//		added at the very beginning of the function. 
// 
//		For example: 
// 
//		extern "C" BOOL PASCAL EXPORT ExportedFunction() 
//		{ 
//			AFX_MANAGE_STATE(AfxGetStaticModuleState()); 
//			// normal function body here 
//		} 
// 
//		It is very important that this macro appear in each 
//		function, prior to any calls into MFC.  This means that 
//		it must appear as the first statement within the  
//		function, even before any object variable declarations 
//		as their constructors may generate calls into the MFC 
//		DLL. 
// 
//		Please see MFC Technical Notes 33 and 58 for additional 
//		details.
