If you write for Windows, MSDN is the best place you can search for answers.
See ya'
I know this doesn't concern your post, but tutorials #21 is the place where sound is used. It does work in my games, but is there a flag I can set in PlaySound() so that more than one sound can play at a time?
Thanks for this great forum

No, for that you'll have to use a different API like SDL, OpenAL or DirectSound... (I prefer OpenAL since it's kinda like OpenGL)
OpenAL I believe to be easier than DirectSound, plus it is like OpenGL. You can use 2d or 3d sound effects which are quite easy to create. Sounds are positioned kind of like translating an object in OpenGL, a simple one-liner. The listener position is the same way, and velocities can also be programmed the same way. Windows API for multimedia kind of blows for games, but works well for simpler apps, in other words, use OpenAL.

Actually, there's a trick that you can use to play multiple sounds with that function... Just spawn a thread that calls PlaySound for every aditional sound. It's a cheap hack, but should work (I haven't tested).
Example:
PlaySound(blabla1);
PlaySound(blabla2);
That will only play the second because it intrrupts the first
Instead have something like this:
int tPlaySound(char *filename)
{
PlaySound(filename);
return 0;
}
CreateThread(..., (void *)tPlaySound, (char *)"blabla1", ...);
CreateThread(..., (void *)tPlaySound, (char *)"blabla2", ...);
that'll play both, or at least should.
