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)). The Screen Updating property controls most display changes on the monitor while a procedure is running. Five hundred lines of text are added to the document. I have changed it slightly so it loops 10,000 times and I execute it 10 times for sample size.
I suspect this is because I am missing something in the reference library but when I check nothing is noted as "missing" and all the obvious Microsoft options are ticked. Echo False but this has no impact on the exporting and I can still see the Excel report populating. Thanks Thanks Eugin, I have tried both of those commands but it makes no difference. I look forward to learning more from you all and hopefully becoming a helpful member myself one day.Use this code template as a starting point (the error handler ensures that these properties are turned back on at the end of the sub, even if it errors) Sub Your Sub() On Error Go To EH Application. Select Next i 'get results results = "Screen Updating not disabled: " & Format(Time - start Time, "hh:mm:ss") & " seconds" start Time = Time 'scenario 2 - screenupdating disabled 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.And after all don’t turn screen updating on/off many times in some loop. And one more note (which you probably don’t want to hear) if you want it quick use C .It is typically 5 to 10 times quicker (don’t catch me here it depends on what you really do) than VBA.
