Can someone out there try this and see if they get the same response.

Open a table as shared from a database in a private datasession.
Then run the following command on the fullpath to the table you have opened, using another form with its own private data session.

lcfile = FULLPATH TO THE TABLE YOU HAVE OPENED e.g. c:\temp\table1.dbf
lnfilehandle=fopen(lcfile,0)

Is the result in lnfilehandle less than 0, which indicates that fopen could not get a readonly open, which I think means that the table is being seen as exclusively opened.

Let me know your results.

I am trying this where the table resides on our Novell server, but I would be interested in any results.

Thanks for your time.
