Thanks Erik, that worked form me. I'm not sure I understand all that is going on in this code, but I plan to study it.

BTW is there a way to prevent the message "Property setting will not take effect until environment reloaded"? It displays once for every table in the database.

The common way to handle this is with a routine that runs before thetables are opened, that loops through the cursors in the DE, and changes the database property depending on some current setting: a registry entry, a public variable, form property, etc. My framework has a ChangeDataPath routine that is called from the form.load that does this.
