Simple MFC question....

Clean and recompile; it''s possible the precompiled headers didn''t update properly.

Don''t listen to me. I''ve had too much coffee.

Yes with mfc and some other applications when ever you start getting some strange errors...before spending hours trying to figure out hit alt-b and then R this will rebuild all.

Always remember this it saves lots of time

I tried that before I posted the message, any other ideas? I can add a new class based on CEditView with no problem. Does it have something to do with the fact that I already have a CHtmlView class in the project?

Are you sure you have put #include <afxcview.h>?

No, i didn''t include that file, i just ran the class wizard. I added that include statement and it didn''t chance the results. I tried to create a new project and add a class based on CListView to it. I got the same error message.

Next, i tried creating another new project but in the setup wizard I chose to use CListView as the base class for my project and I then added a class based On CHtmlView to the project and everything work properly. Why doesn''t it work when I do the oposite.

I also tried to create a project that was not based on the document/view architecture. I then added a class based on CListView to that project. Again I get an error message telling me that the base class is undefined.

I still don''t like MFC.

Can you post the code where your class that derive from CListView is declared?

thx

Did you specify the derivation in the ClassWizard? Or did you add it later?

Make absolutely sure that the first file that your .cpp file includes is "stdafx.h"

then right under that you can include or whatever it is

When you derive a class with the Wizard you have first to choose beteewn:

MFC Class
Generic Class
Form Class

I want to think you did it with the first option. If you do it so, you only have then to add #include <afxcview.h>

That''s all, really, I have done it now

Hi.
My mind is similar to yours, but I know where you are.

Things to check:
1) Project|Settings|C/C++|Pre-compiled header:
for StdAfx.cpp: Generate Pre-compile header: Stdafx.h
for others .cpp: Use Precompile header: Stdafx.h
2) Every .cpp file includes StdAfx.h at the TOP
3) all your #include <afx*.h> should be inside StdAfx.h
4) It is also good (for myself ) to have STL included in StdAfx.h
5) Rebuild-All.

p/s: 0) Which version of MSVC you are using? My office have MSVC5 .
