I'm just getting started with windows programming, and am looking for some reliable information on this subject. Is it preferred technique to mix program code written with MFC classes and functions with non-MFC, ordinary C++ windows code? I understand that this can be done, but, I have no experience actually mixing MFC classes with traditional user defined classes and objects. I would appreciate any generalized suggestions, or, citations of specific references. Thanks.

Yes, you can feel free to use non-MFC classes in your code, especially for code outside the GUI. Note that MFC also provides a number of non-GUI utility classes that you may find useful.

MFC is just a set of classes that wrap Win32 functionality. You'll NEED to write your own classes in addition to do anything non-trivial with MFC, I would have thought, and to the compiler, there is no real fundamental difference between your classes and Microsofts ( except I trust yours will not leak memory ).

Do you mean C++ *windows* code, or just C++ code ? I'm not sure why you would want to mix Win32 and MFC code, but it can certainly be done.

Whoever has a ON_WM_CHAR() Message Map in place and the Wnd has focus.

Yeah that sounds right...
But when I try to set the focus to m_pMainWnd
in InitInstance with m_pMainWnd->SetFocus() I still don't get
WM_CHAR in the frame window ?
Can u help?
|

So you've checked with Spy++ or WinSpector to see if the WM_CHAR is actually getting to your window right?

|
|
Yeah I tried both with Spy++ and
Breakpoing but I never saw WM_CHAR for framewnd
|
|
|
|
|
Well it sounds like it doesn't have focus or something is preventing WM_CHAR from getting through. Are you seeing WM_KEYDOWN, WM_KEYUP in Spy++??

Yes I see them but they go to the CView window...
Even when I change the focus to the frame window they still go there (to CView window)

Put TRACE statements in your CView::OnSetFocus() and CView::OnKillFocus() and you will probably find the View has focus, even though you think the MainFrame does.
Why do you want to get at keystrokes in your MainFrame anyway.

Ah ... 
Thanx Neville now I understand it.
MFC always switch the focus to CView and that's why my WM_CHAR never goes
to MainFrame.
I don't have a particular reason to get the keys in MainFrame...
I just start lerning MFC and I was wandering why CView but not MainFrame gets
WM_CHAR
Well 10x again for the help

The MFC Framework is a large and reasonably complex beast. Document/View is great stuff, but sometimes you have to fight with it to do what you want.
If you do need to get keys in your MainFrame then use CMainFrame::PreTranslateMessage(). That's what I do in ED (see sig).

Hi
I write a sound (*.wav) file, but when I want to play the file with sndPlaySound I get a little blurp from the PC speaker. The particuler file is played with other applications, and other files play fine in my program. The file is closed before I play it. What is wrong?
|
|
|
|
|
what options are you using?
you can also try the PlaySound function
|

I've tried PlaySound, same effect.
|
|
|
|
|
what are you sending as the second parameter to sndPlaySound?
|
|

Joshua Nussbaum wrote:

at the moment it's:
sndPlaySound("c:\\myKlanke\\DieSin.wav",SND_NOSTOP | SND_ASYNC);
|
|
|
|
|
have you tried it with just SND_ASYNC?
or try SND_SYNC
|
|
|

Joshua Nussbaum wrote:

just tried both, still same result. Maybe I should just try different flag settings...?
|
|
|
|

can you run your code on a different computer, just to illiminate the possiblity of a hardware or driver issue.
