Thanks Dennis, I was afraid of that. i am not too good at writing the code so
I am pasting the code I'm using below (i got it from this site and it works
great). Please let me know exactly where to put the error handler as the code
appears to have one already.
I'd like to ignore the error which is "you entered an expression that
requires a form to be the active window. No action is required.
Here is the code which I use to quit Access when a main form has been
inactive for 40 minutes. Thanks again for your assistance!
Private Sub Form_Timer()
'Sub Form_Timer()
' IDLEMINUTES determines how much idle time to wait for before
' running the IdleTimeDetected subroutine.
Const IDLEMINUTES = 40
Static PrevControlName As String
Static PrevFormName As String
Static ExpiredTime
Dim ActiveFormName As String
Dim ActiveControlName As String
Dim ExpiredMinutes
On Error Resume Next
' Get the active form and control name.
ActiveFormName = Screen.ActiveForm.Name
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 call the IdleTimeDetected subroutine.
IdleTimeDetected ExpiredMinutes
End If
End Sub
