Thanks in advance.

I would say, learn to program instead of using Wizards, stay away from MFC
for all but the simplest of programs, and ask questions in the right places.
In your case a Windows programming group like
comp.os.ms-windows.programmer.tools.mfc. Your question has nothing at all to
do with the C++ language.

What's a box?

See the welcome message posted twice per week in comp.lang.c++ or
available at http://www.slack.net/~shiva/welcome.txt

This issue is covered in Marshall Cline's C++ FAQ. See the topic
"[5.9] Which newsgroup should I post my questions?" It is always good
to check the FAQ before posting. You can get the FAQ at:

1. Don't top-post.
2. If you are told to read the FAQ, do so.
3. (In case you still haven't guessed) Tree-view controls are OT in c.l.c++
