Well, there are two "standard" ways to do this, neither of which can be done natively from runrev. The first is to call the WinAPI function GetDriveType(). If the result is DRIVE_CDROM then you've found your drive, otherwise check the next drive. This would be straightforward to code as an external. The second way is to look at HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices\ in the registry, take only the keys that start with \DosDevices\, and work your way through those. Unfortunately, the runrev queryRegistry() function doesn't work that way - you have to give it a fully qualified keypath and can't enumerate through the possibilities. The registry trick also has the drawback of possibly not working across all Win versions. I haven't looked at them all, so I don't know for sure. It does work on our Win2k systems here. In short, I think you're stuck with a bit of C coding in an external dll. -- -Mark Wieder [EMAIL PROTECTED] _______________________________________________ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
