 //	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.

	// 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
