Excel macro screenupdating not working
And, this tremendously slows down the macro execution, which is what I was trying to eliminate by setting Screen Updating=False in the first place. Copying a whole bunch of info from one workbook to another.Is there a more thorough way to turn off ALL screen updating so this macro can execute faster and will not show changing windows when it hits the Windows. Maybe it could be designed more efficiently...however, just wanted to write a few quick and dirty lines of code and let the processor do the work. Screen Updating=False seems to have this 'exception'.But, as you say, this is not necessary; full context can provided as: Workbooks(bnw). There is a word that you can use with Application that will neutralise all the alerts that Excel can send your way.
Similar to selecting ranges and objects to perform an action in the sheet, an explicit reference to the sheet also slows down processing. For example, the following code references the same cell (value) six times: Function Return Fee Slow() Select Case Range("I4") Case 1 Return Fee = Range("I4") * 10 Case 2 Return Fee = Range("I4") * 20 Case 3 Return Fee = Range("I4") * 30 Case 4 Return Fee = Range("I4") * 40 Case 5 Return Fee = Range("I4") * 50 End Select Msg Box Return Fee, vb OKOnly End Function At the very least, Return Fee Slow() makes two explicit references to I4.Admittedly, with today's fast systems, simple macros won't always need optimization.However, if you're working with a complex custom application, these easy-to-implement changes should improve efficiency.That way, the workbook won't recalculate unless you force it to by pressing F9. Display Status Bar = False 'macro code Application. For instance, entering a value into a cell triggers the Worksheet_Change event. The optimized code is more efficient and less prone to runtime errors.Calculation speed probably isn't a large performance factor is most normal workbooks though, and it can have unexpected results, so use it sparingly—as needed: Application. A few won't be noticeable, but if the macro is complex enough, you might consider disabling events while the macro is running: Application. The commented lines show the Sheet and Table object references.
