Thanks for the reply. That's actually how I was doing it before I found out that you could pass parameters using SetTimerEx. Even with this method you need to declare several arrays for your different commands, and I'm just not sure if that's a good method... I also read that GetTickCount()'s not very stable and tickcount() expires after 24 days of non-stop playback (although that's still a hell of a long time!).
