what drive letters are your devices.

u can find the paths and drive letters but not sure about the cdrom drive or DVD drive.

u may have to find them all then look for file to verify on the top level its indeed the place u need.

That's the main problem.

In my Pc the CD-rom drive letters are E and F but in another PC they will be another different letters.

If I create a game which reads data from a CD, I must get the CD-rom drive letter before it starts to work.

Is there no way of getting the possible CD-ROM drives and then make the program search for the path it self.

You can use the "drivelist" command to get a list of all drives on the machine then search each drive in turn (except A of course!) for a file you know exists and is part of your game. When you find it, you've got their CD drive. Then save that value into a text file which you load the next time your game is run - if the file has gone the 2nd time around, repeat the first procedure and create the text file again (if, say, they've changed their drive letter). Not wonderfully "pretty" way of doing it - but it will work.

Cheers,

Thank you very much.

I've got DB, not DBPro.

Will "drivelist" work with DB??

we have the same idea there rich, looking for a file to verify.

maybe this could be a noted component to adress in some later patches about cdrom support.

interesting method, I'll keep that in mind when I'll ever have to use it...

you might first check 'popular' cdrom drive letters like 'D:' or 'E:', in most cases you won't have to check another drive after that

Thank you very much. That's what I've though. I'll use an empty file to recognize what CD is inside.
