Excel macro application screenupdating false
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.
This means that the Excel screen can look like it has "gone crazy" while the macro is running.
The reason it speeds up code is because Excel no longer needs to repaint the screen whenever it encounters such commands as Select, Activate, Large Scroll, Small Scroll and many others. Screen Updating=False should be placed at the Start of your macro like shown below Note how we have set the Screen Updating back to True on completion.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 .Disabled Enabled 0.61909653 2.105066913 0.619555829 2.106865363 0.620805767 2.106866315 0.625528325 2.102403315 0.625319976 2.0991179 0.621287448 2.105103142 0.621540236 2.101392665 0.624537531 2.106866716 0.620401789 2.109004449 There is one important thing to know about screen updating which I didn’t see in any previous answer.From my own test I find out that turning screen updating off and on takes about 15ms (tested in C# via Excel Interop).
