// 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.
