Otherwise, you will need to use the Windows Sleep API function if you are working in e.g. As an alternative, you may choose to wrap the required Excel-based functions or Do…Loop statements into a custom function to make them easier to use/remember (with the added benefit of making your code easier to read): Public Sub PauseExcel(Dim waitInSeconds As Long)Īpplication.Wait VBA.DateAdd("s", waitInSeconds, VBA.Now) However, it is also important to note that there is a very small (but real) risk that your Office application will freeze if your computer has a hiccup. I most often use the Sleep function (system32.dll) to pause code execution, because it is the most accurate and legible of the three methods. The Do.Loop result is also faster than the Excel-based functions, but slower than the Sleep function: It is cumbersome compared to the previous two options, but less so if you wrap it into an easy to remember and use procedure. However, you will be able to execute Public sub procedures from the Developer menu of the xlRibbon. While active, you can do normal sheet and cell operations, but you will not be able to execute additional code directly from the Visual Basic Editor. Private Declare PtrSafe Function GetTickCount Lib "kernel32" () As Long Instead of putting the process that the Office application is running on to sleep, it calls the CPU clock counter directly using another API call: ' Returns the amount of milliseconds that have elapsed since Windows was started: Within the loop, DoEvents is called to allow keyboard and mouse events to occur normally. These examples will help you automate your tasks and inspire you to sharpen your VBA skills. Personally, I have never encountered a real-world scenario where I needed to use this method, but it exists: Public Function WaitAsync(numberOfSeconds As Long)Īpplication.EnableCancelKey = xlErrorHandlerĮndTick = GetTickCount + (numberOfSeconds * 1000) Supercharge your productivity with these useful macro codes. Demo Resultįor this method, accuracy improves by a factor of ~10 over the Excel-based functions:
Below you can find a complete overview.The key cannot be used to break out of Sleep.
