I am making an SDI application with split windows and different views for each side, like Windows Explorer.  I am having troulbe derving the CTreeListView classes.  I must reference the CList/TreeView derived class to set the runtime class in CreateView.  I included the header files for those classes in the implementation file of CMainFrame.  When I build it gives me the error: "CTree/ListView:base class undefined"  in the header files of CTree/ListView.

This error happens because the CTreeView/CListView classes aren't covered by 'stdafx.h'
by default. To include them, put this line into your stdafx.h:

#include <afxcview.h>

Hope that helped :)
