This is the MCI control code that I wrote for my UglyCD
player. It is fairly full featured, but if you need more, feel free to modify it to your needs. I
have neglected the error checking code, and every call to mciSendCommand should really be checked for
its return value. As usual, this code is usable at your own risk. If you have any questions, you are
always free to ask.
