How to Close Program with a Count Down Timer




How to Create a Count Down Timer

If you want to close a form that there is no action taken by the user in certain time frame you can set the counter to count down by second. If the timer is reaching the set amount of seconds then the command will take an action. For this example, I want to put a count-down timer on my Login form. If the user does not login in 1 minute then the Access will close. I will show how to in the steps below.

Step #1 Set Global variable

Declare a form Global variable at the top of VBA of the current form to hold the seconds expired since Form was opened. Set TimeCount as Long.

Option Compare Database
Option Explicit
‘Declare a Form Global variable to hold the
‘seconds expired since Form was opened.
Dim TimeCount As Long

Step #2 Add a text box

Open the design view of the form you want to add a text box for a counter. You can delete a label of textbox and leave only the text box and name it “txtCounter.” You can format the font, size, or color of your textbox if you want.

add text box

Step #3 Set Timer when Form is Opened

We need to set the timer interval when form is loaded under the On Open Event Procedure in Property Sheet. Set TimerInterval = 1,000 since 1,000 milliseconds (tics) = 1 second.

event procedure

Private Sub Form_Open(Cancel As Integer)
‘Set the Form’s Timer to 1 second intervals (1000 tics = 1 Second)
Me.TimerInterval = 1000
End Sub

Step #4 Write code on the Timer Event

Also we need to write a count-down counter under the On Timer Event Procedure. In this example, I will set time frame for 1 minute or 60 seconds. The counter will increment by 1 and display the value on the text box “txtCounter” as 60- Counter. If the counter is 10 then 50 will be displayed on the text box. I also add If Statement to display a number in red color when displayed 20 or less as shown on the picture below.

Private Sub Form_Timer()
'Increment the TimerCount variable by 1
 TimeCount = TimeCount + 1
 'Display the current seconds remaining in the 'text box corner of form
 Me.txtCounter.Value = 60 - TimeCount
 'If the Seconds Counter (TimerCount) is now equal
 'to 40 seconds then the text color changed to Red
 If TimeCount = 40 Then
 Me.txtCounter.ForeColor = vbRed
 End If
 If TimeCount = 61 Then
 'Close the Access Program when the counter is equal to 61 seconds
 DoCmd.Quit acQuitSaveAll
End If
End Sub

count down 19
