Excel macro screen updating
Programming techniques are demonstrated through real-world examples.
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!
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.
Hence I created this generic wrapper to lock the window updates.

Open method and it defaults to open the file in Slide Show mode. The routine below illustrates a manner of woring around the default behaviour and opening the file for editing.
All those Screen Updating = False's you see is called "sheer desperation". I can still enter the workbook and it is screenupdating away even right after the line set it false. Screen Updating = False" in the immediate window it works as expected. Thanks Colin Correct, when you step through in debug mode the screenupdating remains turned on. To test it properly, try this: Put a commandbutton on your sheet and paste in Application. Net) | Coordinates, Vectors and 3D volumes I've experienced this problem, with code that previously worked!
Well, the function is quite long, but you're looking at the function's entry point. The immediate window says True, then False, then True again as expected, but the code doesn't seem to have any effect on the application. If all of this happens, then you know it is working correctly.
