Is there a generic VB code that will hide all spreadsheets in a workbook but
one. I use this method to prevent users from using the file after disabling
macros. If they Disable Macros, all they see is a spreadsheet with a message
saying 'to use this file they have to Enable Macros'. When Macros are enable
and the file is closed/saved, all sheets, except the one with the message,
are made invisible and the workbook protected (locked), and when the file is
opened with Macros Enabled all sheets except the one with message are made
visible and the workbook is unlocked (not protected).

The problem is that a user can add a new spreadsheet to the workbook and the
code I use will not make the new spreadsheet invisible on closing. The code
I use is:

sheets("Sheet Name").visible=false

Is there a way to make all sheets invisible or a toggle command to reverse
the existing visible property for all sheets in a workbook? Or perhaps,
there is a better approach. Any assistance will be appreciated.
