>Thank you Sergey,
>I appreciated your help again. Allow me to use this reply to ask you very simple for you question. In our app I am trying to lock all tables so we can do the process that requires exclusive access to those tables. Now, users can use those tables exclusive already at that moment. I opened FoxPro in another session to simulate another workstation and used a couple of the tables exclusive. In the script I am checking if those tables are used.
