Me.Requery can be used to refresh the database in your form.
Im sure theres much better ways to do it, but you can have it continuously refreshing by doing the following: (this syntax may not be exact, I dont have access on this pc and this is coming from memory)
1) Type a line that says 'TimerInterval = 250' in the Form_Load or Form_Open section of the code.
2) Type a line that says 'Me.Requery' in the Form_Timer section of the code
What this does, is every fourth of a second your form will refresh the database in spite of what you are doing. Like I said, this is a pretty cheesy way to do it, but im a noobie and this works for me 8)
If you dont need it to be happening all the time, all you need to do is find out what event you can add 'Me.Requery' to, that the user will be activating when the database needs to be refreshed.
Hope this helps a little.
