When I add a class derived from CTreeView with ClassWizard, Visual C++
4.0 throws this error message at me:

MyProgTreeView.h(8) error C2504: 'CTreeView' : base class undefined

the line look like this:

class CMyProgTreeView : public CTreeView

Someone please tell me what is going on!

Try:

#include "afxcview.h"

You need to add this. I added it to stdafx.h

#include <afxcview.h> // MFC Common controls

Try including <afxcmn.h> in your header.

You need to include #include <afxcview.h> in stdafx.h. (It's noted in the
overview for CTreeView in the help file.)
