Could somebody help me play a CD with MCI Commands through C++ by sending me a tutorial or a link to a tutorial. I am kind of new and the stuff I found about it is really complicated...mabey the stuff you guys send me is easier!?

Smelly,

MCI is awfully easy to use. It involves basically using the mciSendCommand, and sending the right commands. You would start out by sending MCI_OPEN to the MCI_DEVTYPE_CD_AUDIO device, then sending MCI_PLAY, MCI_SEEK, MCI_STOP, etc. to control the playing.

There is full source code in the VC++ documentation. Here is the listing of a file from the sample app CDINFO:
