So it makes sense to use error handling to make sure that the updating is switched on no matter what.
You can do it like this: Normally the screen updating is switched back on just before "Exit Sub".
End With" instead of going through the whole "chain of command" to access the object.
Like this: You will also save time by putting the most likely cases near the top.
This tells the program to go back to the label "Before Exit", and screen updating will be switched back on before exit.
In normal mode Excel will recalculate, if you change a cell value that affects other cell values.
If the macro writes to cells or switches between worksheets, the screen can flicker a lot.
Use the following statements to disable and enable this feature: Disabling screen updates won't disable the Status Bar, which displays information during normal operations, including what your macro is doing. For example, the following recorder code applies italics to C4: C62: Macro2() accomplishes the same thing with one line of code and without selecting the range.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.It's not changing the value, it's using the value in a simple expression.When the macro has finished, you switch the updating back on.It looks like this: It is a pain, if the program gets an error and crashes before it has switched the screen updating back on.
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.
