Hi,
I want to play a wave file when I click on a button
#include <MMSystem.h>
....

int CDialog::OnBtnClick(...)
{
PlaySound("123.wav", NULL, SND_FILENAME);

}


But PlaySound and SND_FILENAME identifiers are not found. Any ideas?
Thanks
Jack

The documentation for PlaySound says:

Header: Declared in Mmsystem.h; include Windows.h

That means you are supposed to include Windows.h, not mmsystem.h

Also note that the next line of the documentation says you must link to
Winmm.lib. Add that filename in 'Additional Dependencies' in the linker
section of the project properties.

Where did the #include <mmSystem.h> appear? Before or after the #include "stdafx.h"? If
before, then this is treated as an ill-formed comment and has no effect! Sadly, you only
gave the #include as if it is the ONLY #include in your application, which I doubt.
Context matters.

To add to what Scott and Joe already pointed out, you may want to use
_T("...") decorator for "123.wav" string literal, or else you may have
some other error in Unicode builds (after you fix the #incldude thing).

Here is the entire module, please take a look, thanks
it still does not compile with identifiers not found (PlaySound and
SND_FILENAME).Strange......
