Ok, this might seem wierd but,

I have a file on disk call 'MyFile.cnv'. It's just a VFP table with a wierd extension. In a method I have:

cTableName = 'c:\MyFolder\Myfile.cnv'
THISFORM.cFile = JUSTFNAME(cTableName)
cStem = juststem(thisform.cFile)

Now, if I use the table in the default DataSession. Run my form (it has a private datasession), and call that method all of the following return .F.

used(cTableName)
used((cTableName))
used(juststem(thisform.cFile))
used(thisform.cFile)
used((thisform.cFile))
used(cStem)
used((cStem))
used(dbf( any of the above )) fails with a 'No Alias found' error.

Shouldn't at least 1 of the above return .T.

The only workaround I could find was trying to open it with LLFF

x = fopen(cTableName)
if x = -1
? 'open'
else
? 'not open'
endif

Anybody have any ideas?
