Using PlaySound in MFC? Possible??? 1

[Rmck87]

Hello, I would like to play a wav file whenever I press a button in a dialog-based MFC Application. So, I have used this code in my include block:

#pragma comment(lib, "Winmm.lib")
#include <Mmsystem.h>

...

and this code to play the file:

if (!PlaySound("C:\\...filename...\\song.wav, NULL, SND_FILENAME)
{
exit(1); //error
}



However, the program will not compile, because it does not recognize PlaySound as a proper identifier. It claims that it is an undeclared identifier. Any help would be much appreciated.

Thanks in advance!

Given that your attempted snippet contains several syntax errors to being with, how about

1. posting actual code, inside [code][/code] tags to preserve readability.

2. posting actual error messages. "an error" really doesn't tell us anything.

Ok, here's the code hopefully a little easier to read:

My includes:

#pragma comment(lib, "Winmm")
#include <Mmsystem.h>
#include "stdafx.h"
#include "ThreadWatcher.h"
#include "ThreadWatcherDlg.h"
#include <cstdlib>

My sound calling block:

if (!PlaySound("C:\\Documents and Settings\\My Documents\\ThreadWatcher\\ThreadWatcher\\containfail.WAV", NULL, SND_FILENAME))
			{
			exit(1); //error
			}

containfail.wav is the filename of the wav file I would like to play.
ThreadWatcher is the name of the application I am writing.



And here are the errors I am receiving:

.\ThreadWatcherDlg.cpp(257) : error C2065: 'SND_FILENAME' : undeclared identifier

.\ThreadWatcherDlg.cpp(257) : error C3861: 'PlaySound': identifier not found

It doesn't like SND_FILENAME, or PlaySound


I just assumed they were related errors, so I only mentioned PlaySound as the error.


Thanks again...

What includes windows.h ?

Also (AFAIK), stdafx.h is the magic file which marks the end of the pre-compiled headers. As I understand it, if you're using pre-compiled headers, then the list of includes before "stdafx.h" has to be consistent across ALL source files. Any variation gets ignored.

I'm assuming that your stdafx.h includes windows.h, in which case the answer would be to move
[tt]#pragma comment(lib, "Winmm")
#include <Mmsystem.h>[/tt]
down a couple of lines, so they're after stdafx.h

you were right. Thank you. "stdafx.h" has "windows.h" included in it, btw.

Thanks for the help!
