If this argument is omitted, Microsoft Excel will wait until the procedure can be run. ![]() If Microsoft Excel is not in Ready mode within 30 seconds, the procedure won't be run. For example, if LatestTime is set to EarliestTime + 30 and Microsoft Excel is not in Ready, Copy, Cut, or Find mode at EarliestTime because another procedure is running, Microsoft Excel will wait 30 seconds for the first procedure to complete. If you do not specify a 'LatestTime' then the macro will run when Excel is available after the 'EarliestTime' has passed. Latesttime - The latest time at which the procedure can be run. Procedure - The time when you want this procedure to be run. In Excel there is also an Application.WaitĮxcel Application.OnTime (Earliesttime, Procedure )ĮarliestTime - The time when you want this procedure to be run. ![]() This method will only be executed if the file containing the procedure is loaded when this line of code is executed and if the file containing the procedure is currently loaded at the time it is meant to run.Īlways use fully qualified macro names: If you start another timer before an existing timer runs, the existing timer is cancelled. Starts a background timer that runs a macro at a specified time.Įach application can only maintain one background timer set by OnTime. This can be used to run a macro at a later time or to execute a procedure at regular time intervals. You may want to refresh the data in your database every 5 minutes. This approach may see some slight delays over a longer duration of time (as we are running code before the schedule), however, it should be good enough.There may come a time when you need to run a procedure automatically at a particular time every day. ![]() The next hit of the button will turn of the schedule. What happens above? When you hit the button the AddSecond procedure will be set to run within a second and then automatically sets itself to run in the next second after updating the timestamp. = Format(TimeSerial(h, m, s), "HH:MM:SS") Remember to select your named range as well as to connect your button to the StartStop procedure.Īpplication.OnTime Now() + TimeValue("00:00:01"), "AddSecond", Schedule:=FalseĪpplication.OnTime Now() + TimeValue("00:00:01"), "AddSecond" You can use the code below to achieve this. When the stopwatch is running it increments the TIMESTAMP cell (a named cell). Using the VBA OnTime function we can also create a simple Excel VBA Stopwatch:Īs you can see in the example above I created a button that launches a Start / Stop sequence. The below will s ave the current file after every 5 min. You can use the VBA OnTime function also to schedule code execution after a specific duration of time. Timeout = TimeValue("21:50:00") 'Set alarm for 21:50 PMĬall MsgBox("The time is " & Format(Now(), "HH:MM")) To do this we use the Excel VBA OnTime procedure: Remember that the VBA Sleep function is not a native VBA function and needs to be declared.Ĭall Application.Wait( DateAdd("s", 1, Now) )Īnother VBA Timer scenario is scheduling procedures to run at a specific time or after a specific time interval like an alarm clock. In case you don’t want to measure time elapsed and instead set an interval or delay between code execution you either use the VBA Sleep or VBA Wait procedures like below. 'Result for 10 minutes and 1 second: 00:10:01 The above is very useful if you want to measure time elapsed in Seconds, if you want to calculate time elapsed in Hours, Minutes and Seconds you can simply use the VBA Now function with text formatting using VBA Format instead:ĭebug.Print Format(currTime - Now(), "HH:MM:SS") VBA Timer with Hours, Minutes and Seconds ![]() StartTime = Timer 'Get current time in seconds The most simple example of a VBA Timer can be made using the VBA Timer function: On the otherhand a practical example can be a VBA Stopwatch which can be useful to measure time elapsed directly in a Excel spreadsheet. Setting timers can be extremly useful if you want to run code as specific time intervals. In this post we will explore the various ways we can set a Timer in Excel VBA as well as how to build your own VBA Stopwatch.
