Originally I thought to ask if there would be an easy way to provide an automatically managed last update field with MS Access.
After some googling I found following approach:
Private Sub Form_Dirty(Cancel As Integer) Me.Last_Update = Date() End Sub
Which seems to do the job. I thought I’d share it with others too (and if somebody has some good points that should be considered, feel free to share them)
You could also put that same code into a BeforeUpdate.
The difference being that the OnDirty will tag the record when you first started to edit the record; while the BeforeUpdate will tag the record just before it gets committed to the database.
The latter may be preferable if you have a user who starts editing a record, goes to a meeting and then finishes editing it an hour later.
