You could save the file on the activate event (or change Thisworkbook.Saved
= true). then in the deactivate event, you could check Thisworkbook.Saved.
If true, no change. If false, there has been a change. [Lightly tested]

Other than that you would have to detect the change yourself (possibly using
the change event).

Note that changing Thisworkbook.Saved can affect the prompt to save before
closing.

Hi All,

Is there any way to check if any cells in a worksheet has been changed? I
want to use a Worksheet_Deactivate() event, but only if there was a change
in
the sheet to avoid lengthy processing.

Thanks,
Stefi
