"undeclared identifier"

[Vlatko]

I want to use the mciSendString API Function in my app but the compiler reports an "undeclared identifier" error. How can i correct this. Should I include some *.h files or what?

Try including Windows.h.

Nope.I've tried that. It still reports the same error.

Include mmsystem.h.
