Hello Chris,
My solution to the same problem is to check for a volume serial number
first, then if there is one, check for the file I'm looking for. You
can do this with the following function...
function GetVolumeSN pDiskLetter
local volumeSerialNumber
-- Supports both "C", "C:" and "C:\" styles
put char 1 of pDiskLetter & ":" into pDisk
set the hideConsoleWindows to true
put shell("dir " & pDisk) into tDirData
get matchText(tDirData,"Volume Serial Number is
(.*)\n",volumeSerialNumber)
if it is true then
return volumeSerialNumber
else
return empty
end if
end GetVolumeSN
If the function returns a Serial Number, I know a disk is located at
that drive letter. I then do my "if there is a file..." stuff. If the
function returns nothing (empty) then I know there is no disk in the
drive and I don't check it.
This seems to avoid the whole "no disc" error in Windows XP SP2. I
don't know about other versions... you'll have to test it out.
I hope that helps!

I would think this has to be a common problem, so I'm wondering how the
rest of you have gotten around it.
The single-user version of our software comes with media content on a
series of CDs. Things have been working pretty well, except in a case
where a user might have more than one CD drive (we're talking Windows
only here). I have written a routine that scans through each available
drive looking for our CD. The problem is, if there is no CD in the
drive(s) at all, a "no disk" error, generated by Windows, pops up. This
error will appear for each drive that does not have a CD in it. My
question is, is there some way to suppress this error? I'm simply using
a "if there is a file" type of check to determine if our CD is in one of
the drives. Is there some other method available to me? A command line
utility perhaps?
Any suggestions would be appreciated.
Thanks,
Chris
