  form:

     #define mmsystem "WINMM.DLL"
     DECLARE integer mciSendString IN mmsystem string, string, integer,;
        integer
     =mciSendString("open cdaudio","",0,0)

2. Add a command button to the form, and set its Caption property to Play. Enter
  the following code in the Click event of the button:

     =mciSendString("play cdaudio","",0,0)

3. Add another command button to the form, and set its Caption property to Stop.
  Enter the following code in the Click event of the button:

     =mciSendString("stop cdaudio","",0,0)

4. Add another command button to the form, and set its Caption property to
  Eject. Enter the following code in the Click event of the button:

     =mciSendString("set cdaudio door open","",0,0)

5. Add a final command button to the form, and set its Caption property to Exit.
  Enter the following code in the Click event of the button:
