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. Well, the function is quite long, but you're looking at the function's entry point.

Screen Updating = False If my Debug = False Then On Error Go To Error Handler I'm afraid that's pretty much it. Screen Updating End Sub As I step through the code when I hove over Application.screen Updating it always says True. Then put it in debug mode and step through with screen updating turned off again, you should find that you still see the numbers going in one by one.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).Display Status Bar = True ''//Make sure that the statusbar is visible For i = 1 To i Max ''// imax is usually 30 or so fraction Done = CDbl(i) / CDbl(i Max) Application.
Status Bar = Format(fraction Done, "0%") & " done..." ''// or, alternatively: ''// status Range.value = Format(fraction Done, "0%") & " done..." ''// Some code....... Display Status Bar = boo Status Bar State ''//Reset Status bar display setting Application.
Screen Updating = False ''//Turn off screen updating boo Status Bar State = Application.
Display Status Bar ''//Get the statusbar display setting 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.
Screen Updating = false" because I saw the yellow highlight go over the line in debug mode. Calculation = xl Calculation Automatic Application. Screen Updating from within the code instead of the immediate window, but I'm fairly sure what I'll find. This function gets called by an event handler that catches a Commands Bar button event (? Basically, we create a menu bar and one of the buttons in our custom "File" menu is labeled "Load Portfolio" which calls this function.

I think that maybe something has broken in my excel because even when I closed out of excel and opened a brand new 2003 workbook with no previous code I was getting the same problem. The interesting thing is that *some* of my modules allow Screen Updating to be set to False, there's only a few that don't.
