I have only two questions to do before to rate this thread as excellent

The first one is: I found that to play sound syncronously I've to insert into the command line the keyword "WAIT". Is it true? And is it needed to not insert it to play asyncronoulsy?

The second one is: is the max output volume level equals to 1000 or not?

Moreover I'd like to have MS documentation about MCI functions. So I've seen both MSDN and other sites, and all the links to the page where should be the documentation is unavailable. Have you a direct link to that? If you don't, it's the same: you've already done a lot for me!
