Vba allow screenupdating

Excel & Word have the Screen Updating method thru which a developer can lock the main window from unnecessarily redrawing itself whilst the macro is being executed. If left alone, redrawing is not only ugly on the eyes it also takes more time for the macro to reach completion.

' This includes both posting free demo projects made from this ' code as well as reproducing the code in text or html format.

' --------------------------------------------------------------------------------' User Defined Error codes Const ERR_NO_WINDOW_HANDLE As Long = 1000 Const ERR_WINDOW_LOCK_FAIL As Long = 1001 Const ERR_VERSION_NOT_SUPPORTED As Long = 1002 ' API declarations for Find Window() & Lock Window Update() ' Use Find Window API to locate the Power Point handle.

By setting Screen Updating to False at the Start of the macro, you will not only stop the constant screen flickering associated with recorded macro, but also greatly speed up the execution of the macro.

One thing you may want to do with your macro to make it run faster and to prevent distracting flashes on the screen is to turn off screen updating while the macro is running.

The following macro lines will, respectively, turn off screen updating and then turn it back on in a VBA macro.

The idea is to use the first line near the beginning of your macro, and then use the second line near the end.

which obviously isn't working because the screen updates a whole lot afterwards. I almost wish this were more complicated; the fact that everything looks so simple is making it difficult to think of what could possibly be happening! So this morning application.screen Updating was working as expected. The test code that I wrote is below: Sub test() Debug. One thing that seems to be common among those modules not working, is that they all contain code that changes worksheets. In any case, it's a real mystery why this happens from one day to another!
