Vba screen updating code www evanhawkdating com
When you run this example, you can compare the respective running times, which are displayed in the message box. Screen Updating = True For i = 1 To 2 If i = 2 Then Application.
Screen Updating = False start Time = Time Worksheets("Sheet1").
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 Resume 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)).
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.
The example hides every other column on Sheet1, while keeping track of the time it takes to do so.
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.Allen Wyatt With more than 50 non-fiction books and numerous magazine articles to his credit, Allen Wyatt is an internationally recognized author.He is president of Sharon Parq Associates, a computer and publishing services company. Keep that on mind if you will execute anything which would take less time.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 .
