Speed up macro screenupdating
The tips are specific to the desktop version because macros don't run in the browser version. Have you noticed that your screen sometimes flickers while a macro is running? Calculation = xl Calculation Automatic Similar to setting the Calculation property to Manual, disabling events can have unexpected results, so use it with careful consideration.This happens when Excel attempts to redraw the screen to show changes made by the running macro. If you use the macro recorder, you may have noticed that it's fond of using the Select method to explicitly reference things.If screen updates aren't necessary while running the macro, consider disabling this feature so your macro can run a bit faster. It works, but it's slow and prone to runtime errors. Then, review the resulting code for Select methods and change them to Range references.
Admittedly, with today's fast systems, simple macros won't always need optimization.
When you really want to improve the speed, I'd advise you to replace VBA by a compiled programming language, based on Active X or Automation (or even more modern?
View = xl Normal View End Sub VBA is interpreted, hence it is slow.
I have an excel file with a VBA code (Not written by me) How this code works is user enters a 6 digit number in a user form, the VBA then checks another sheet and if this 6 digit number is present on the worksheet. List Index = -1) Then Exit Sub With Sheets("psdata stage cals").
If it does, it changes the stage, but if it doesn't it adds this 6 digit number to the worksheet It used to work perfectly, but now because the excel file has grown in the number of rows, almost 6000 rows, this code is become very slow, takes up to 20 seconds to update the sheet Can someone please help me speed this code up, or suggest another way to acheive it The code is below Private Sub cmd PSDUdate_Click() Dim x If (Me.
