If you rightclick on the worksheet tab, you can select View Code.

Then use the code window (right hand side) to choose Worksheet and Activate from
those two dropdowns at the top of the code window.

Then you could modify what you see to look like:

Option Explicit
Private Sub Worksheet_Activate()
   MsgBox "Don't print this page"
End Sub

And you can select that sheet
then Format|Sheet|Hide
to hide the sheet.

If your macro breaks, it could be that you've used .select's within your code.
These aren't usually necessary--and since the sheet has to be selected (and
therefore, visible) to select any cells on that sheet, the code breaks.

You have at least a couple of choices.

Rewrite your code to avoid the select's.  It may be more difficult, but it's
probably worth it to make the code easier to understand/update later.

Or (not recommended)....

Have your code turn off the screenupdating, unhide that sheet, do your real
work, hide the sheet, and turn screenupdating back on.

It may seem like a quicker fix, but I bet in a couple of weeks when you have to
tweak the code, you'll see the problem.

(Recorded code can work, but it's not efficient and it's too hard to see what's
going on.)

Hi Risky
