Excel – VBA Timer Example v1.0.1

1. A query. If I have two templates that are using a timer like the example described here, each one independently acquiring electrical data from a PI Data (Excel) database, how can I avoid the two conflicting? in versions prior to office 2016 nothing else separated each excel in separate windows, but now, in 2016 it is not separating the timers and the VB runs them at the same time and the templates remain stuck.

2. Excelent code.
   Thank you so much .

3. Thanks for the example. I hooked the timer up to 2 buttons, so i could control when it was functioning.

   very useful indeed.

8. Very helpful to me. Thanks!!

9. Great code – many thanks

10. Very cool procedures. You need to edit this line of code to make it work:
    CHANG Cell Reference in “interval = CDbl(Range(“D8″).Value)” to
    interval = CDbl(Range(“D7”).Value)

    Very elegant and nice. Solved my problem

11. Thanks for posting this code. I was looking for an example of a on_timer function for Excel that matches the functionality of MFC. This example was more helpful then the Microsoft help.

    Appreciate it.

14. Hi Andrew,

    try the following as VBA code on a worksheet (e.g. table1):
    ”————————————–
    ”Require that all variables be declared
    Option Explicit
    Dim Execute_TimerDrivenMacro As Boolean
    ‘

    Sub Start_OnTimerMacro()
    Execute_TimerDrivenMacro = True
    Application.OnTime Time + TimeValue(“00:00:01”), ActiveSheet.Name & “.OnTimerMacro”
    End Sub

    Sub Stop_OnTimerMacro()
    Execute_TimerDrivenMacro = False
    End Sub

    Public Sub OnTimerMacro()
    If Execute_TimerDrivenMacro Then
    ‘ Do something e.g. put the actual time into cell A1 of the active sheet
    ActiveSheet.Cells(1, 1).Value = Time

    ‘ At the end restart timer
    Application.OnTime Time + TimeValue(“00:00:01”), ActiveSheet.Name & “.OnTimerMacro”
    End If
    End Sub

    Private Sub Worksheet_Activate()
    ‘Start the timer driven method when opening the sheet
    Start_OnTimerMacro
    End Sub

    Private Sub Worksheet_Deactivate()
    ‘Stop the timer driven method when opening the sheet
    Stop_OnTimerMacro
    End Sub
    ”————————————–

    Hope that helps.
    Kind regards,

17. Dear Sebastian,

    I am trying to update my portfolio by picking up the quotations at Yahoo every 20 minutes. I would like to understand the way this macro works. the button start timer activates which macro. the code I have to put where you say “put your code here” does not seem to execute. Can you please help

    Thank you

18. Das Programm verwendet die dafür vorgesehene Excel-VBA-Funktion
    Application.OnTimer(AufrufUhrzeit as Date, NameMeinerSub as String)
    wie in der Excel-Hilfe vorgeschlagen:
    Application.OnTimer( now()+TimeSerial(0,0,5) , NameMeinerSub as String) ‘ 5 Sekunden
    Bug/Problem der Funktion: Wenn die Uhr des PC um 1 Stunde vorgestellt wird, dauert der nächste Aufruf 1 Stunde!
