Set the worksheets property to xlVeryHidden the user will not be able to
unhide them unless they are in vba which you can password protect. or use
something like

ActiveWorkbook.Worksheets(3)= (xlVeryHidden)

I have hidden worksheets on my program. How can I prevent someone from
unhiding a worksheet? I know how to protect the worksheet from changes but
there are certain worksheets I want to keep from others eyes.
Thanks
