I used that MCI sendstring API code that you're so fond of posting on a regular basis but when i try to use it (on those occasions when it doesnt hang VB), I get the following error msg:

"MMSYSTEM257 Invalid MCI device. Use the ID returned when opening the MCI device"

I cant see why it wont work as it's a pretty simple copy-and-paste job (i only changed a couple of "Private" declarations to "public" ones)

Any ideas on where i've gone wrong?

Thanx
