Supporters of this claim mistakenly believe that VBA “resets itself” at the end of a macro or procedure, and/or not resetting Screen Updating to True has no bad effects.
Occasionally a parroted claim will pop up in the Excel cybersphere that resetting Screen Updating from False back to True in a VBA procedure is pointless and unnecessary.
Setting the calculation mode back to xl Calculation Automatic will automatically trigger a recalculation of the worksheet, so there is no need to press the F9 key after your macro runs.
You may notice that when your macros run, your screen does a fair amount of flickering.
Here’s some sample code that shows how and what to shut off while your code runs. Display Page Breaks ‘note this is a sheet-level setting ‘turn off some Excel functionality so your code runs faster Application. Be sure to turn it back on right before your code ends.
Future versions of Excel will invariably support new, or stop supporting existing, VBA methods and properties, so it’s an unnecessary risk to not reset Screen Updating.
Third, there might be times when you are running code in sequence and you want to see what you did while you are doing it. Macros Two and Three are called by Macros One and Two, but you cannot see the results of your code until the last macro is completed, unless you had set the Screen Updating back to the way it was in each macro. Screen Updating = False Msg Box "Screen Updating is off now !! Value = "Two" Msg Box "Screen Updating is " & Application.
Not only did I see a huge variety in how Excel is being used, you also pointed out various tips and tricks for writing fast VBA code in Excel.
In this post I’m going to share with you the most important performance tips I know about.
Speed is how quickly your VBA procedures perform their intended tasks.
