Playing an audio CD using the windows API?

How can I play a track from an audio CD using the windows API. can anyone please provide the code.


thanks in advance



John.

Use the
Private Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" (ByVal lpstrCommand As String, ByVal lpstrReturnString As String, ByVal uReturnLength As Long, ByVal hwndCallback As Long) As Long

Download the file attached. Contains code for playing CDs and basically, the whole deal for making a CD Player.

I can't download your text file. I get an error that says, HTTP error 400, page cannot be loaded or file removed.



Pls help


thanks in advance

I downloaded it but it looks like s**t.
