I have a very perculiar problem to sort out.

The problem is I have a number of users in a system which is determined within a program which I cannot hook into. But each user has a directory called profile and when they are in the system there is a file in that directory which cannot be opened. A typical example would be:

There is a user Peter which has a permanent number called user 26.

Therefore in the program loadpoint it would like:

\\PROFILE\USER26\Insystem.DBF

If you try and open this file when the user is NOT in the system everything is fine. If you try and open the file if the user is in the system then you get a message 'File access is denied U:\Profile\User26\Insystem.dbf'

What I would like to do is to scan each of the user directories to see whether the users are in the system. Is there anyway I can check to see if you can open this file for example if you can't I get a MessageBox User is in system or User is not in system.

Many Thanks
