There is no reason that you can't use the windows API from an MFC application.  MFC provides a wrapper to most (but not all) of the API, where it doesn't just use API calls.  (You can use API calls even where it does provide a wraper, but that defeats the purpose of using MFC).

If you have a CWnd object that you and you wish to pass its window handle to the function, I believe you cna just specify the CWnd instead of the handle (not a pointer to the CWnd), as I think there is a HWND conversion operator.  If not, then you can just specify the m_hWnd data member.

Let me know if you have questions.

It is customary to explicitly use the global scope.  E.g., ::SHGetSpecialFolderLocation(...)
It lets the programmer use the API even if there's a similarly named member function in scope (as is the case with lots of MFC functions).

Good point.  That insures there is no problem in the future if an interface function with the same name, but different parameters, is added to MFC.

Unfortuantely, communication is not my specialty.  (even with humans--my wife would say.)
