Free Excel Help One drawback with recorded macros in Excel is that the code produced is often very inefficient.
It also means that we cannot tell the macro recorder to not record our steps of selecting cells, sheets and scrolling around, even though the selecting of cells, sheets and scrolling is not needed in true VBA code.
Range For repeat = 1 To 30 For Each cell In r cell. Value Mod 2 = 0) Then ' if i is even, color the cell white cell. Range For repeat = 1 To 30 For Each cell In r cell. Value Mod 2 = 0) Then ' if i is even, color the cell white cell.
I’m currently on a project to improve the performance of a particular workbook.
And usually when you write your code, you’re just trying to get things to work. But after a while you notice your code is beginning to get very slow when it runs. I mentioned that the issue is that the screen is constantly updating, which is causing the code to run slowly. The code runs much faster when there’s less real estate to update on your screen. Screen Updating = True End Sub Now the code runs at 1.4 seconds for me, which is a huge improvement.As a result, of all this selecting and scrolling, the screen flickers whenever your recorded macro is played back. Screen Updating Those that are familiar with VBA code may also be aware of the term Application. Unfortunately those that really need to know about this term (those that can only record macros) are often not aware of it.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.The idea is to place Excel into manual calculation mode, run your code, and then switch back to automatic calculation mode.
Setting the calculation mode back to xl Calculation Automatic will automatically trigger a recalculation of the worksheet. Calculation = xl Calculation Manual You may notice that when your macros run, your screen does a fair amount of flickering.
This means that if you run a different subroutine after the one above and you haven't added the line of code to disable screen updates to it, you'll be able to see the screen updating in the background.
