From my own test I find out that turning screen updating off and on takes about 15ms (tested in C# via Excel Interop).
Programming techniques are demonstrated through real-world examples.
The Screen Updating property controls most display changes on the monitor while a procedure is running.
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").
You can find a version of this tip for the older menu interface of Excel here: Turning Off Screen Updating. A VBA add-in to quickly insert any of the sample code found on our site directly into the Visual Basic Editor, save your own frequently used code, and more!This tip (2498) applies to Microsoft Excel 97, 2000, 2002, and 2003.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)).
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.
Remember to set the Screen Updating property back to True when your macro ends.
