when using theSoundPlayer to play a wav file, how do i determine if the wav file is still being played?

If you use PlaySync the method will not return until the file is finished, otherwise there is no event when the player stops. For example you could use PlaySync in a background thread and Invoke back to your UI thread to signal when it has finished.

 is there also a way to play a sound or vibrate the phone when making an outgoing call?  i'd like to make the phone vibrate when a call is connected or when a call doesn't make through.  i tried using systemstatus but i think sounds and vibrations are nulled when an outgoing call is being made.

The system disabled loudspeaker sound when a voice call is active. I suspect vibration is disabled for the same reason - the user will be holding the phone to their ear and it could come as a bit of a shock!
