Please can you point me in the direction of compiling the spreadsheet as a
COM add-in

Thanks

A note here........Excel internal passwords for sheet and workbook
protection
are very easily cracked.

Posted by JE McGimpsey........................

In general there is no internal XL security that can't be bypassed by a
moderately interested person who can find these newsgroups. See:

Your best bet for anti-piracy would be to redesign and compile your
spreadsheet as a COM add-in.
