FileXtra4 & CD Reader/writer Drives

Question

I have been using FileXtra4 and it has worked wonderfully for
me. I have found the method for locating the CD volume path, very
useful
Recently, I have been using it on PC's with only one CD/DVD
drive. This drive is both the reader and the writer. When I have a
projector on the desktop that is looking for the CD volume, it can
not find it.
Also, this problem doesn't occur on laptops, where the reader
& writer drives are combined.
Has anyone else experienced this? Any solutions?

Answer 1

I believe the problem occurs after it has identified the
reader writer CD/DVD volume (using the FileXtra4 VolumeTests())
So this the code that runs after that:
on test_FileExists
global gFile, gDrive, gPath, gTest
fxObj = xtra("FileXtra4").new()
thePath = gDrive & "Content\Files\start.dxr"
gPath = thePath
put thePath
--get's result of sort after file existence
put "test_FileExists(): length of path == " &
string(thePath.length)
put "fx_FileExists() returns " &
string(fxObj.fx_FileExists(thePath))
errCode = fxObj.fx_ErrorNumber()
gTest = errCode
put "FileXtra4 error code: " & string(errCode)
--if file there go to it, else if it ain't there - alert.
if errCode = 0 then
gFile = "success"
go next
else if errCode <> 0 then
put " error string: " & fxObj.fx_ErrorString()
alert ("Please place the S.T.O.P. Passport CDROM in to your
CD drive and re-launch this programme")
Quit
end if
fxObj = 0
end
