He never asked about protecting his code. He asked about a trusted
developer and implied he wanted his code to open with a macro prompt. You
introduced concern about protecting the code. No one suggested
distributing
the code with nothing but a certificate. You have mixed two different
topics together as Harald illuminated.

Where did anyone ever get the idea that I was telling him people could
hack
his signature? I never said that. He said that "the school can not
market
them..." This tells me he wants to SELL it. Sorry, but I would never
SELL
any Excel product that only has a digital signature.

There are two very different issues he Protecting code from
thieves,
and
signing code so that it can be allowed to run in schools computers. A
signature is no protection against theft, it is a "run me without
further
questions, I'm from a trusted programmer" label. Any good hacker can
steal
the code, but the signature in question can not be hacked or imitated
from
the file as far as I know.

HTH. Best wishes Harald

My point exactly. So if the OP is wanting to SELL his technology,
digitally
signing it really buys him no protection at all. Is that correct?

well certainly they can sign it themselves ann. But without BILL'S
certificate they can either only sign with a self-made certificate
or
with
their own purchased certificate.

Are you saying no one can export all the code, copy the sheets
to
a
new
book, and sign it themselves?

So you saying anyone can get the code, modify it, and then
certify
that
they
are Bill. I think not.

You need a Digital Signature to market something like this
Bill.

However, I don't recommend it because anyone can then
copy/crack
your
code
and send it to others. If you have a great idea, my
recommendations
a
1) Get a web developer to make a web-based application for
you,
to
which
you
let users subscribe on a monthly basis.
2) If web isn't feasible, then have a VB application
created
from
it,
or
a
COM add-in, either of which is far harder to
reverse-engineer
than
macros
in
an Excel workbook.
As it stands now, anybody could take your macro home,
self-sign
it,
and
make
themselves the trusted developer at work.

My school ICT manager, although impressed with my Excel
programming
(his
words, not mine!) of Interactive Whiteboard Maths Excel
workbooks,
tells
me
that the school can not market them because of their use
of
MACROS -
(really
VBA code behind Excel). Other schools probably won't
have
the
courage
or
imagination to allow my macros to be used my the machines
on
their
networks.

I am assuming that I can't write code to "correct" their
macro
security
to
"low".

What should I do? I notice a phrase "trusted macro
developer"
on
a
dialogue
box. Could you explain what that means and how someone
is
credited
with
that
status.

Thanking in anticipation
