To do this, simply press Esc or Ctrl + Break. The DoEvents function in the loop enables you to interrupt the code execution. Next, the procedure loops from 1 to 5000 and updates the. As will become evident in the next section, this is crucial in terms of performance! ScreenUpdating to False, just like we did in our Application.ScreenUpdating VBA tutorial. We also turn the screen updating off by setting. StatusBar with the string “False” without setting it to its default value, “Ready”!

This may sound strange, but otherwise it would be impossible update the the. StatusBar with a string, but its default value is the boolean value False. The procedure starts by storing the current value of the.
In practical situations, if a program containing a loop takes a long time to complete it’s really helpful to track its progress that way. In this simple procedure we use VBA to repeatedly update the value of the Application.Statusbar in the lower left corner of the Excel window inside a loop. Insert the code below into a standard code module: With this in mind, let’s present a very basic and nifty example of VBA DoEvents usage!

We’ll present some performance test results with important lessons attached to them and then we’ll show you how to balance the yielding of code execution with performance considerations.įinally, we’ll discuss the generic applications of the DoEvents function in Excel and when not to use it in your VBA macros. The second part of this introduction is dedicated to exploring how the DoEvents function affects performance. This is logical, since, by yielding execution to other events and processes, Excel temporarily halts the code execution while the operating system handles these other events or processes. The DoEvents function in VBA is no exception since it will cause the execution time of your program to increase. However, as the saying goes, all good things come with a price. In the first part of this tutorial, we’ll show you how to circumvent this and other similar problems by using the VBA DoEvents function. We’ve all made a mistake in a code which causes an infinite loop or something Your program will, in theory, never terminate and Excel will remain unresponsive until you shut down your Excel application! So frustrating. Only few things in life are more frustrating than trying the halt the execution of a program and not being able to because Excel has become unresponsive. The VBA DoEvents function also enables interruption of code execution so it’s easier to stop a running macro. VBA DoEvents yields execution of your macro, so your computer processor will be able to simultaneously run other tasks and recognize other events.
