Playing WAV file

I need my app to play a simple wav file to notify user of certain things.
I'm currently using the "sndPlaySoundA" API, but it doesn't allow me to set the volume that it must play the file at.

Is there a way to set the volume for this API or another easy way to play a wav file and set the volume JUST for that specific file? (so that it doesn't change the system volume)

Anyone??

Cant rember where i found this (probly here at the forums) but i use this with mp3s.

In a modual.

VB Code:

Thanks for the reply but it looks to me like that sets the master volume, which is not what I want to do. I just want to change the volume at which my file is played.
