Re: [MS_AccessPros] record locking

Hendra-

First, I never use "Edited Record" - I prefer No Locks. The downside is if two users edit the same record at the same time (A starts to edit, then B starts to edit, then A or B save before the other is done), one user will get an error message stating that the record was changed by another user. You can trap this error in the Form_Error event and issue your own message.

Technically, your test should have worked, however (as long as you were trying to edit three different records). Are you sure you have the "Open Databases by Using Record-Level Locking" checked in Access Options / Advanced / Advanced?
