![]() ![]() Wait 1 second and expect a Message Box to open with the message “Hello World!”. The code below will schedule the HelloWorld Sub to run in 1 seconds.Ĭall MsgBox("The time is " & Format(Now(), "HH:MM"))Īpplication.OnTime EarliestTime:=timeOut, Procedure:="WhatHour", Schedule:=True Useful when you want to cancel a previously scheduled Procedure Excel VBA Alarm Clock If False clears a previously set procedure. If True schedules a new OnTime procedure. It makes sense to use this variable when your user is working on the file, so as not to interrupt any activities This allows Excel for some flexibility when prioritizing Procedure execution together with other Excel (or other MS Office applications) Events such as Cut, Copy or Find. This is the latest time when the Procedure should be executed. The time (Date variable) when the Procedure is to be executedĪ string with the name of the Procedure which is to be executed The syntax of the VBA OnTime function: Application.OnTime( EarliestTime, Procedure, LatestTime, Schedule) Using it recursively allows you to create a recurring / repeating event which lets you schedule periodic VBA Macros to run when working on Excel Workbooks. It allows you to execute any Excel VBA procedure after the specified amount of time (delay). 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.One of the many useful features of Excel and other MS Office applications, of which little users know of is the VBA OnTime function. 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. ![]()
