If any of you out there are excel vba programmers or general programmers
familiar with copy protection programming, I am interested in communicating
with you.

I have one excel file with 6 or so worksheets therein. I am interested in
selling the file either as a runtime program OR in modified excel format, so
long as I can protect the file from being used upon unauthorized
duplication.

I would appreciate the opportunity to discuss my needs with any member of
this group qualified to work on these issues for me. I am prepared,
natually, to pay for qualified professional programming time.

Thank you.

Bruce,

I'm very familiar with copy protection programming.
There are literally hundreds of ways that you can "try" to protect your work
in Excel.
Absolutely, none of them work.

Anyone with access to this (or the other) newsgroups (or access
to the Excel newsgroup archives) can find a way to circumvent any copy
protection
that you might try to implement.

It all depends on the "audience" of people that you're trying to distribute
your
worksheet to.
In my instance, the people that I work with wouldn't have a clue and will
never get
access to any of the worksheets that I've "copy protected" for my office.
Hundreds of people that participate in this newsgroup would be able to break
any
copy protection that I used in a matter of minutes.

If you're going to "sell" it, your copy protection "can" be broken.
Fortunately, there are a lot of people that would have no clue.

I'm sure that you'll get other replies pretty much stating what I just
wrote.
If you don't get an answer that satisfies your needs you can e-mail directly
and I'll be happy to discuss what can and can't be done but the bottom line
is that what you want to do can't be done effectively.

John
