Tim,
The bad part about using playsound - is the fact that not all pocket pcs are
created equal. Filenames do change from time to time - which is why
playsound will play the default system wav file if it can't find the file
you specified as a parameter. In order to make sure that the wav file that
you want to play is on the device - you would have to include it with your
application.
Actually there is a function in C++ that produces a simple DTMF beep...
I've wrapped it in a dll that can be PInvoked from .NET - and it works from
the 10 + pocket pcs that I have. Let me know if you would like the source -
happy to help.
