When I started reading more into improving the efficiency of your code I understood what it was for but how much of an effect does Turning off screen updating will only make a difference to execution time if the code interacts with Excel in a way that causes changes to the screen content.

The grater the amount of screen changes the bigger the impact will be. Other application settings that can make a difference to execution time are Calculation and Event handling. Enable Events = False ' Code here Clean Up: On Error Resume Next Application. Calculation = xl Calculation Automatic Application. Enable Events = True Exit Sub EH: ' Do error handling Go To Clean Up End Sub Sub test Screen Updating() Dim i As Integer Dim numb Switches As Integer Dim results As String 'swap between sheets this number of times numb Switches = 1000 'keep track of time Dim start Time As Double start Time = Time 'swap between sheets 1/2 (need both sheets or this will crash) For i = 1 To numb Switches Sheets(1 (i Mod 2)).

From my own test I find out that turning screen updating off and on takes about 15ms (tested in C# via Excel Interop).

Keep that on mind if you will execute anything which would take less time.

Screen Updating = True Try running it and you should see a short pause followed by column A getting filled with numbers.

Whenever you have a task to automate, you can usually go down the VBA route. Maybe later you add some features here-and-there, making your VBA code more powerful. Color = vb White End If i = i 1 Next cell ' offset i to alternate column coloring i = i 1 Next repeat Msg Box "Total time was: " & (Timer - start Time) End Sub Before moving on, let’s get a better understanding of why this is taking so long. Color = vb White End If i = i 1 Next cell ' offset i to alternate column coloring i = i 1 Next repeat Msg Box "Total time was: " & (Timer - start Time) Application.

This means that the Excel screen can look like it has "gone crazy" while the macro is running.

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.

Please follow the below steps to execute the VBA code to save the excel file. Step 2: Press Alt F11 – This will open the VBA Editor.

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!

We can notice the screen updating while updating Sheet1.
