Excel macro screen updating
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.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.You can use the Worksheet Function property in Excel VBA to access Excel functions. For example, place a command button on your worksheet and add the following code line: When you click the command button on the worksheet, Excel VBA calculates the average of the values in cell A1 and cell A2 and places the result into cell A3. You can manually recalculate the workbook by pressing F9. In most situations, you will set calculation to automatic again at the end of your code. To insert the formula itself into cell A3, use the following code line: Sometimes you may find it useful to disable screen updating (to avoid flickering) while executing code. You can instruct Excel VBA not to display alerts while executing code. For example, place a command button on your worksheet and add the following code line: When you click the command button on the worksheet, Excel VBA closes your Excel file and asks you to save the changes you made. To instruct Excel VBA not to display this alert while executing code, update the code as follows. As a result, Excel recalculates the workbook automatically each time a value affecting a formula changes.It's best to do it at the beginning of the macro, but you can also switch it on and off repeatedly as many times as you like in a macro (if there is something specific you want to have updated while the macro runs).
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.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. 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.
