>HI!
>I have three identical databases with exact same tables. Lets say first is 'A', second 'B' and third 'C'. Initially DE was populated by tables from 'B'. When I try to switch to 'A' or 'C' or even try to start in 'A' or 'C' I get an error saying, "File l:\...\..\B doesn't exist". I checked the procedure several times which replaces the database name with currently open database, either being 'A' or 'C', and debugged it several times. The database names and other properties are replaced without any problem but when VFP reloads DE by DE.Opentables() it gives me the error.

I guess that during this process you can get in troubles by any bound control on your form.
