We can notice the screen updating while updating Sheet1.
Please find the below example for Screen Updating Property of application object in excel VBA.
I have a windows application that, when the user opens the application, it sets the size of the form, maximizes the form, then re-establishes the distances of the splitters: 'Sets userforms size to almost the size of the users screen, then maximizes it Dim working Rectangle As System.
Worki Try the Suspend Layout and Resume Layout methods as shown below. Suspend Layout() 'Sets userforms size to almost the size of the users screen, then maximizes it Dim working Rectangle As System.
We can observe that there is no screen updating till running the macro.
Don’t forget to reset the Screen Updating valsue as TRUE at the end of the macro.
From my own test I find out that turning screen updating off and on takes about 15ms (tested in C# via Excel Interop).I always assumed it was just used so that it didn't scare end users into thinking their PC was about to crash.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.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.Step 3: Insert a code module from then insert menu.The example hides every other column on Sheet1, while keeping track of the time it takes to do so.The first time the example hides the columns, screen updating is turned on; the second time, screen updating is turned off. Hidden = True End If Next c stop Time = Time elapsed Time(i) = (stop Time - start Time) * 24 * 60 * 60 Next i Application.Screen Updating = False 'swap between sheets 1/2 (need both sheets or this will crash) For i = 1 To numb Switches Sheets(1 (i Mod 2)). Screen Updating = True 'get results for part two results = results & vb Cr Lf & "Screen Updating IS disabled: " & Format(Time - start Time, "hh:mm:ss") & " seconds" 'show results Msg Box results End Sub Firstly I've been using the script written by Richie (UK) Post #7 Here It simply iterates through a loop changing the value of i in one cell.I have changed it slightly so it loops 10,000 times and I execute it 10 times for sample size. This example turns off screen updating and then adds a new document. You must set the Screen Updating property to True when the procedure finishes or when it stops after an error.
