Hi,
I've got problem with playing sounds from windows.form program that contains folder sounds with 1 sound.wav

spWave.SoundLocation = "sounds/blue_buff.wav";
spWave.Play();

This patch saying is wrong and program crash ... any ideas?

My first doubt is on the location variable. To be sure, Hard code the full absolute path starting from drive letter like "c:...".

Your current working directory depends upon what type of project you have created. Using Visual studio might be different from others.

Also there is very little reference to the rest of your code i.e. if the class type of spWave is correct etc.
