Access turn off screenupdating
Access turn off screenupdating - Free Online
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)).
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., Excel and VBA expert Curt Frye introduces object-oriented programming and shows how to automate routine tasks and provide custom functionality to enhance Excel performance and efficiency.This course introduces the Visual Basic for Applications programming language, covers creating subroutines and functions to hold code, and provides a solid grounding in the Excel 2007 object model.Programming techniques are demonstrated through real-world examples. I always assumed it was just used so that it didn't scare end users into thinking their PC was about to crash.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.
I've had a search and can't find anything along these lines...
I have changed it slightly so it loops 10,000 times and I execute it 10 times for sample size.

From my own test I find out that turning screen updating off and on takes about 15ms (tested in C# via Excel Interop).
Keep that on mind if you will execute anything which would take less time.
