In this tutorial, I provide all the information you need to understand what are Excel VBA events and how to start using them in your macros. This blog post focuses on the topic of Excel VBA events. As I explain below, knowing how to do this allows you to create VBA applications that are able to do things that would otherwise be impossible. In fact, in this Excel VBA tutorial alone, I explain 9 different ways in which you can execute a Sub procedure.Ī very useful way of executing a macro is by telling Excel that a Sub procedure should be executed when a particular event occurs. Within Excel, you have several different options for calling or running a VBA Sub procedure.

Otherwise, all of your work designing and coding the VBA application would've been in vain. Some people argue for doing it as a matter of 'good form', just in case code is added below later.Once you've created a macro, you need a way to execute or call it.

OTOH, On Error Then GoTo 0 is superfluous in this context, since we are exiting the procedure immediately afterwards. Certain edits in VBA cause that to happen, especially when a VBA procedure is excecuting.) (I am not sure of the conditions under which VBA reset is performed automatically. Usually, no timer is running when timer_on is executed, because either the workbook was just opened (after restarting Excel) or timer_off had been executed successfully before.Īs I noted, even the global variable mTimerTime might be unintentionally zero if VBA reset is performed, either manually or automatically. It is necessary when that timer is not yet running and when mTimerTime is zero for any other reason. Dave's method starts and reschedules the time one sec after each 5-min epoch (00, 05, 10, 15., 50, 55), not literally every 5 On Error Resume Next is absolutely necessary and prudent. (Sigh, VBA reset does not stop all Simply doing Now+TimerSerial(0,5,0) is not a correct alternative. The solution is: declare Dim mTimerTime as global variable at the top of the module.Ĭaveat: If VBA is 'reset', either by you manually or sometimes VBA does it automatically (!), even the global variable will be reset to zero, and timer_off will not abort a running timer as expected. So if you manually run timer_off, then re-run timer_on, you will have two timers running, possibly scheduled to expire at the same time. The problem is: since mTimerTime is a local variable in timer_off and initialized to zero, the OnTime Schedule:=False fails to stop any currently scheduled timer. If you close the Excel application, then restart it and execute timer_on just once, I think you will see that your code runs as intended.
