Excel 97 - Sheets Tabs Rows Collumns

[TheFIDDLER]

My current project involves trying to prevent the user from showing sheet tabs, and of revealing columns and rows.

I can hide the menus easily enough. I am looking to code within the program to trap the events, and to cancel them or to reset back to my original state.
I can code it as:

If ActiveWindow.DisplayHeadings = true then ActiveWindow.DisplayHeadings = false
If ActiveWindow.DisplayWorkbookTabs = true then ActiveWindow.DisplayWorkbookTabs = false

or simply - since the time it takes to check, it may as well perform the action

ActiveWindow.DisplayHeadings = false
ActiveWindow.DisplayWorkbookTabs = false

My question is as to the most efficient place to put it.
Any suggestions? Or if I can trap the events and only have the code run if needed.
