Vba screen updating off
The next time we run the procedure we don't want to be able to see the screen flickering in the background.To achieve this we need to add a single line of code to the subroutine, just below the variable declarations.If you thought those were your only options – you were wrong.VBA thankfully allows you to also use another function called Do Events. Seriously, it doesn’t do anything more that handle all MS Office events. The Sleep function pauses the entire process for a certain delay specified in milliseconds.The drawback of using VBA Sleep is that it freezes Excel until the delay is done. Wait is a native VBA function that pauses code execution until a certain time is reached.
The Sleep function is not available by default in VBA, and has to be imported from the #If VBA7 Then Public Declare Ptr Safe Sub Sleep Lib "kernel32" (By Val milliseconds As Long Ptr) 'MS Office 64 Bit #Else Public Declare Sub Sleep Lib "kernel32" (By Val milliseconds as Long) 'MS Office 32 Bit #End If your process entirely – preventing any input or interaction with your application (even breaking code execution). This means you can keep working on your Excel Workbook during the delay.
It's probably also worth changing the colour that we're using so that we can see when things have changed. This time you won't be able to see the macro carrying out its tasks; once the subroutine has finished the screen will update once at the end to show you the final result.
The Screen Updating property resets at the end of a procedure.
This means that if you run a different subroutine after the one above and you haven't added the line of code to disable screen updates to it, you'll be able to see the screen updating in the background.
You may have noticed that when running the procedure with screen updates disabled the subroutine appeared to run faster.
