    Eh?

    There is [I presume] no difference between playing a 2 second, 20 second or 3-4 minute .WAV file.

    Perhaps this article will explain what you need to do:
    http://www.microsoft.com/msj/0698/sound/sound.aspx

    This assumes you are using Windows. If you are using Linux/Unix to write your game, I can't help, and you'll need to explain this to us.

    Thanks for the response, but I was looking for something more like the playsound function.

    Thanks

    And why do you think you can't use the PlaySound function in the first place - the above was just what I found when searching for "Play DirectSound" - if you are not using DirectSound bur prefer to use the multimedia functions, then I don't see a problem with that.

    So, what is it you are after, a full example version of PlaySound?

    Thanks, I have looked on the internet and I have been unable to figure out how to use playsound. I am looking for a example on how to use it. Im very confused on how to use playsound.

    Thanks

    So, why don't you post a small piece of the code you are working on, with suitable questions on the bits you don't understand/can't get to work.

    It looks to me like the PlaySound is really simple to use - something like:
    Code:
    #include <Windows.h>
    
    int main()
    {
         TCHAR name = "c://blah.wav";
         BOOL f;
    
         f = PlaySound(name, NULL, SND_FILENAME);
         if (!f) {
             printf("Error\n");
         }
         return 0;
    }
    I haven't tried that, and of course, the "name" has to be a valid wave-file of some sort.

    Here is the Code
    Code:
    #include <iostream>
    #include <string>
    #include <windows>
    #include <cstdlib>
    #include <mmsystem.h>
    #pragma comment(lib,"Winmm.lib")
    using namespace std;
    
    int main()
    {
    	cout << "Hello world" << endl;
    	system ("PAUSE");
    	
    PlaySoundA("fanfare.wav", 0, SND_RESOURCE | SND_NODEFAULT);
    return 0;
    
    	return 0;
    }
    That was the best I could do (and it wont complile)

    Thanks

    Code:
    PlaySoundA("fanfare.wav", 0, SND_RESOURCE | SND_NODEFAULT);
    Are you sure that the red code is correct?

    I thought "SND_FILENAME" would make more sense from the parameters you use - but I'm not sure at all.

If no association is found in the registry, the name is interpreted as a filename.
    I don't think "fanfare.wav" is a resource, but rather a filename.

    How can I put a full length song (3-4 Minutes) in a game.
    For PlaySound(), there is a limit to the WAV file size. When I once tried to play a full song with PlaySound() I got an error.

    MSDN says:
    Remarks
    The sound specified by pszSound must fit into available physical memory and be playable by an installed waveform-audio device driver....
    I assume "available physical memory" depends on how much RAM you have, how much RAM is being used by Windows and other applications.... And maybe how much physical RAM Windows is willing to allocate to your program....

    codeproject.com has a DirectSound example that can play a whole song.

    You mean, my example that I posted earlier isn't good enough? It does exactly what I said you should change, using SND_FILENAME as the documentation says. I'm sorry, I'm not going to write the same thing again. Of course, you WILL have to change [or copy a file to match] blah.wav. But I think you are capable of that.

    But since I wanted to make sure I wasn't telling porkies, I produced this, that runs on my machine:
    Code:
    #include <windows.h>
    #include <stdio.h>
    
    int main(int argc, char **argv)
    {
    	BOOL f;
    	f = PlaySound("c:\\winnt\\media\\tada.wav", 0, SND_FILENAME);
    	if (!f) 
    		printf("Error\n");
    	else
    		printf("Done!\n");
    	return 0;
    }
    Of course, I missed the note about the wav file fitting in memory, so if you want to play 4 minutes of 40 KHz samples, you are looking at needing 40MB or thereabouts. (40 KHz * 2 channels * 2 bytes per sampel * 240 seconds)
