Hello. I did at lot of Googling about the subject. The article you are referring, talks about receiveing and handling WM_DEVICECHANCE messages. In this case, there are no such messsage, and that's the problem. My guess is that it's a driver issue. My question was (and still is): What's the mechanism for the driver to detect that the CD/DVD has been replaced (and consequently send a WM_DEVICECHANCE message)? In other words: What do I have to do with the CD's/DVD's in order to make Windows (and it's cdrom driver) discover that CD/DVD has been replaced?
