>In my project there are two applications that use a common table to relay information from one to the other. At one point I need to open the table exclusively so it can be cleaned up. If the App1 has it open and App2 is trying to open it exclusively then the" FIle Access is Denied" error comes up. Is there a way to determine by App2, whether or not App1(or any other app) has the table opened. This is a free table.

If you're running the app in VFP 5.0 there's a function call: ISEXCLUSIVE( cTableAlias ) that will do what you want.
