If you turn off the screen updating, and your macros takes some time to finish,
the user may think that the computer has stopped to respond. Because of this it's a good programming
rule to inform the user of the macro progress by displaying a message on the statusbar at the bottom of the screen.
Here is an example :
Sub StatusBarExample()
Application.ScreenUpdating = False
' turns off screen updating
Application.DisplayStatusBar = True
' makes sure that the statusbar is visible
Application.StatusBar = "Please wait while performing task 1..."
' add some code for task 1 that replaces the next sentence
Application.Wait Now + TimeValue("00:00:02")
Application.StatusBar = "Please wait while performing task 2..."
' add some code for task 2 that replaces the next sentence
Application.Wait Now + TimeValue("00:00:02")
Application.StatusBar = False
' gives control of the statusbar back to the programme
End Sub
