I am writing an SDI .exe in W98 using VC++ 5.0.  I want to display a List Control in Report mode with several columns, the size of the main window, with menus.

Using the class wizard, I derived a CMyListView class from the CListView base class, which produced the relevant .h & .cpp files.  The build produced Error C2504: Base class undefined!

You need to include the relevant header in your stdafx.h

Make sure you include afxcmn.h and afxcview.h

Here is the relevant section form my stdafx.h

#include <afxwin.h>         // MFC core and standard components
#include <afxext.h>         // MFC extensions
#include <afxole.h>         // MFC OLE classes
#include <afxodlgs.h>       // MFC OLE dialog classes
#include <afxdisp.h>        // MFC OLE automation classes
#include <afxcmn.h>                  // MFC support for Windows Common Controls
#include <afxcview.h>
#include <afxtempl.h>

You can omit the OLE lines if you are not using OLE

You can omit the afxtempl.h line if you are not using CList, CMap or CArray

did you create the new class as a generic class or as an MFC class ?
