Vba screen updating code
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. Turn screen updating off to speed up your macro code.You won't be able to see what the macro is doing, but it will run faster.This means that the Excel screen can look like it has "gone crazy" while the macro is running.One thing you may want to do with your macro to make it run faster and to prevent distracting flashes on the screen is to turn off screen updating while the macro is running.
Whenever you have a task to automate, you can usually go down the VBA route. Maybe later you add some features here-and-there, making your VBA code more powerful. Color = vb White End If i = i 1 Next cell ' offset i to alternate column coloring i = i 1 Next repeat Msg Box "Total time was: " & (Timer - start Time) End Sub Before moving on, let’s get a better understanding of why this is taking so long. Color = vb White End If i = i 1 Next cell ' offset i to alternate column coloring i = i 1 Next repeat Msg Box "Total time was: " & (Timer - start Time) Application.
The following macro lines will, respectively, turn off screen updating and then turn it back on in a VBA macro.
The idea is to use the first line near the beginning of your macro, and then use the second line near the end.
