I have an MFC-based application that uses an extension DLL. The extension DLL exports a class(CExtensionClass) that is to be used in the main application(CMainApp).
If there is a class(CMyClass) defined in the main application project and I want to use it in the extension DLL, is that possible?
Right now if I include the "MyClass.h" header in the CExtensionClass.cpp file, everything compiles OK. When I create an object, myClassObj, then the compiler throws the "unresolved external symbol" errors.
Thanks for the help,
