One reason this helps is that if you’re updating (via VBA) several different ranges with new values, or copy / pasting from several ranges to create a consolidated table of data, you likely do not want to have Excel taking time and resources to recalculate formulas, display paste progress, or even redraw the grid, especially after every single operation (even more so if your code uses loops). The benefit here is that you probably don’t need Excel using up resources trying to draw the screen since it’s changing faster than the user can perceive.
Just one recalculation and one redraw at the end of your code execution is enough to get the workbook current with all your changes. Enable Events display Page Break State = Active Sheet. Since it requires lots of resources to draw the screen so frequently, just turn off drawing the screen until the end of your code execution.
Here, the user does not require to see the processing or even the excel application window until work is complete and I want the work to be faster. Calculation = xl Calculation Manual End Sub Public Sub YK_End() Application.
Restore EE = Value End Property Public Property Get Restore Screen Updating() As Boolean Restore Screen Updating = this. Adding in a bunch of error handling is necessary, but I didn't want it to clutter the code.
I want to start off this post by thanking everyone who sent in their examples in response to my January request.

Calculation End Sub Public Sub Disable App Settings() With Application . Also, there are at least 4 properties that are regularly persisted, but usually only 3 of the 4 are persisted. I've written a class, and a test harness that shows how it can be used in a stack, and without explicitly restoring the properties. Also, you'll want a test that covers this nasty gotcha: The constants were designed so that a developer could alter the default behaviors without having to edit any code.
Calculation = xl Calculation Manual End With End Sub Public Sub Restore App Settings() With Application . That's potentially a lot of private variables to declare and assign, and it can quickly get confusing about when and where properties are set and unset. You'll want a test for each property you're persisting, that fails when the getter doesn't return the value that was persisted; you'll want a test for each getter again, that fails when it doesn't return the expected value after it was saved and then modified.I beleive setting one property to false may not require setting the other to false. Calculation = xl Calculation Automatic End Sub Sub Loop Example() Dim Cell As Range Call YK_Start Columns("B: F"). So, here my question is - Which one(/both) of Application.screenupdating/Application.visible should I set as false? My understanding is that both properties can increase throughtput of the vba task though screenupdating property is to be used when the user should view the application but not the updation made until when required but visible property is to be used when the user does not require to see the window. In this post I’m going to share with you the most important performance tips I know about.
