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).
========================================= Private Sub Form_Timer() On Error Resume Next ' IDLEMINUTES determines how much idle time to wait for before running the IdleTimeDetected subroutine Const IDLEMINUTES = 1 Static PrevControlName As String Static PrevFormName As String Static ExpiredTime Dim ActiveFormName As String Dim ActiveControlName As String Dim ExpiredMinutes
' 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 quit the application Application.Quit acQuitSaveAll End If End Sub =========================================
