[newbie][long]Pure virtual function call :(

Noone Nowhere

Hi.

I'm Visual C++ 6 newbie. I'm trying to compile some simple
source from Rick Leinecker's book (Visual C++ Bible). It's
MFC AppWizard exe. I'm usign VC++ 6. The problem is, when I
compiling I get an error like below. I think sources are ok.
Maybe it's my environment problem? Some configuration mistake
(now it's default). However, sources are available:
http://www.haragi.webpark.pl/learnide.zip
If someone would like to help... ;) sorry about so low level
of my question, but I really don't know how to solve the problem.
I've found similar threads on newsgroups, but without any answer.
Google found also http://tinyurl.com/bacyw, and
http://support.microsoft.com/kb/q181265/, but I don't think it's
the exactly my problem way to solve. Maybe I'm wrong, but as I said,
I'm newbie ;). Big thanks for answer.

That's no low-level question -- as you call it. If you got the project off a
cd from the book -- it should work as-is -- however -- if you created it and
re-entered the code, there could be many conflicts -- try turning of
precompiled headers in your project.
