Newbie code question (and maybe I need a 1hr tutorial for some $)

[Stone]

Hello,

I am a competent vb6 programmer and understand a bit of C structures.
However the C++ system is mystifying me..I simply will have to learn it
to now.... I have 2 questions.

1> Can anyone tell me how code "Program 4. Microphone Select"
at http://www.codeproject.com/audio/ADMixer.asp can be changed to simply
self close by clicking the IDOK button routine programmatically? This is the
simple effort that triggered my current angst.! (I 'think' need to set a
state
in BOOL CSelectDlg::OnInitDialog" to fake the IDOK event or trigger to
the OnDestroy routine). Frankly I know this is simple, but I am guessing!

2> Can someone spare 30 minutes or a hour to walk me through this example to
explain this in more detail. I have VC6++ and would be happy to pay for the
consulting. Let me know and I'll get you an email to contact me directly

Thanks... -stone

That question has nothing to do with C++, and everything with Windows
and MFC. You are more likely to get a good peer reviewed anwser if you
post this question to a Windows or MFC newsgroup such as
or
To learn what is topical here or not and
which newsgroup is the best place to ask a particular question, read

You are probably better of with a couple of good books, at least one
about the C++ language itself (without OS specific stuff) and one about
Windows/MFC programming. This is cheaper and more effective than
consulting; C++ is not the kind of language you can learn in a day or
even a month. Book reviews can be found here:

Good luck with your study!
