As per below comments
/*

which

// }
*/
AFX_MANAGE_STATE needs to be used with exported functions .
Thats true but that doesnt mean it shouldnt be used elsewhere. In your
case, since you want to access app module's state when accessing
mainwindow, use the following:
AFX_MANAGE_STATE(AfxGetAppModuleState()) ;
This should return a non null main window pointer.
Also, why are you using a Regular DLL? Why not an extension DLL?
