It’s not as fast as it used to be and it can begin to get pretty frustrating waiting a long time for your code to finish. Color = vb Black Else ' else, color the cell light gray cell. If you think about it, if there were of the screen to process, it should run faster, right? Now it should make sense why it’s a good idea to turn off Public Sub Add Content To Sheet() Application. Color = vb Black Else ' else, color the cell light gray cell. If this sounds like you, then Public Sub Add Content To Sheet() Dim start Time As Double start Time = Timer Dim r As Excel. Range("A1: P30") Dim i As Long Dim repeat As Long Dim cell As Excel. Try this out: shrink your Excel workbook window to a smaller size and run the code again. Screen Updating = False Dim start Time As Double start Time = Timer Dim r As Excel. Range("A1: P30") Dim i As Long Dim repeat As Long Dim cell As Excel.
Whenever you have a task to automate, you can usually go down the VBA route. Maybe later you add some features here-and-there, making your VBA code more powerful. Color = vb White End If i = i 1 Next cell ' offset i to alternate column coloring i = i 1 Next repeat Msg Box "Total time was: " & (Timer - start Time) End Sub Before moving on, let’s get a better understanding of why this is taking so long. Color = vb White End If i = i 1 Next cell ' offset i to alternate column coloring i = i 1 Next repeat Msg Box "Total time was: " & (Timer - start Time) Application.
And usually when you write your code, you’re just trying to get things to work. But after a while you notice your code is beginning to get very slow when it runs. I mentioned that the issue is that the screen is constantly updating, which is causing the code to run slowly. The code runs much faster when there’s less real estate to update on your screen. Screen Updating = True End Sub Now the code runs at 1.4 seconds for me, which is a huge improvement.
command or whenever formulas need to be re-calculated.
Switching off the screen updating is extremely simple to do.
Most of us use macros to automate processes that we repeat or that require specialized knowledge.
Regardless of why you use macros, you want them to run as quickly as possible.This isn't commonly used when your macro is short and quick to run, but longer/slower macros can employ this as it speeds up the runtime of the macro.This is because Excel no longer has to refresh the screen every time the macro uses a Scroll, Activate, Select, etc.I have a slide that includes a (inserted) chart and an inserted Excel worksheet object.I can open each object to update the underlying data, but I can't do it without the objects actually opening on screen.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.
