Question

I would like a 1 second delay in my code. Below is the code I am trying to make this delay. I think it polls the date and time off the operating system and waits until the times match. I am having an issue with the delay. I think it does not poll the time when it matches the wait time and it just sits there and freezes up. It only freezes up about 5% of the time I run the code. I was wondering about Application.Wait and if there is a way to check if the polled time is greater than the wait time.

   newHour = Hour(Now())
   newMinute = Minute(Now())
   newSecond = Second(Now()) + 1
   waitTime = TimeSerial(newHour, newMinute, newSecond)
   Application.Wait waitTime

Answer 1

I use this little function for VBA.

Public Function Pause(NumberOfSeconds As Variant)
    On Error GoTo Error_GoTo

    Dim PauseTime As Variant
    Dim Start As Variant
    Dim Elapsed As Variant

    PauseTime = NumberOfSeconds
    Start = Timer
    Elapsed = 0
    Do While Timer < Start + PauseTime
        Elapsed = Elapsed + 1
        If Timer = 0 Then
            ' Crossing midnight
            PauseTime = PauseTime - Elapsed
            Start = 0
            Elapsed = 0
        End If
        DoEvents
    Loop

Exit_GoTo:
    On Error GoTo 0
    Exit Function
Error_GoTo:
    Debug.Print Err.Number, Err.Description, Erl
    GoTo Exit_GoTo
End Function
