Just copy the following code to the "Timer" event of any form you think your users may keep open for an extended period of time. It can be on multiple forms if you wish, but is usually used on the main form or switchboard.
You only have to do 2 things:
1) Change is the IDLEMINUTES value. Right now it is set to one minute. Change it to the number of minutes you wish before the application is shut (30 or 60 is common).
2) Set the "Timer Interval" property on the form to the value that you want to run the code (1000 = 1 second). I usually set it for 5 minutes (300000).
That's it.
=========================================

Const IDLEMINUTES = 1

Dim ExpiredMinutes

If Err Then
ActiveFormName = "No Active Form"
Err = 0
End If
ActiveControlName = Screen.ActiveControl.NAME
If Err Then
ActiveControlName = "No Active Control"
Err = 0
End If
' Record the current active names and reset ExpiredTime if:
' 1. They have not been recorded yet (code is running for the first time).
' 2. The previous names are different than the current ones (the user has done something different during the timer interval).
If (PrevControlName = "") Or (PrevFormName = "") Or (ActiveFormName <> PrevFormName) Or (ActiveControlName <> PrevControlName) Then
PrevControlName = ActiveControlName
PrevFormName = ActiveFormName
ExpiredTime = 0
Else
' ... otherwise the user was idle during the time interval, so increment the total expired time.
ExpiredTime = ExpiredTime + Me.TimerInterval
End If
' Does the total expired time exceed the IDLEMINUTES?
ExpiredMinutes = (ExpiredTime / 1000) / 60
If ExpiredMinutes >= IDLEMINUTES Then
'.... if so, then reset the expired time to zero ...
ExpiredTime = 0
'.... and quit the application
Application.Quit acQuitSaveAll
End If
End Sub
