Hey all, Need a wee bit of information.

What code is involved in making a sound go off from a file? like for example,
Lets say i have a button, and i click it, i want it to activate a sound file that i have on my computer somewhere. How would i do that?

And furthermore, what fileformat would it have to be in order for the sound to work?

Any help would be appriciated
