MS EXCEL (NEED HELP)

[Wade]

We have a very extensive application that requires the use of Ms excel to
run. We are getting ready to launch our product to the public but we are very
concerned about protecting our worksheets and projects etc. We have very
extensive passwords and scrambling etc. We have found out that the passwords
can be very easily hacked into. We know that eventually we will need to
rewrite it in machine language, but we have spent 6 years writing this
application and it is not feasible at this time.
Does anyone know of a way to further protect/encrypt or...?
Does microsoft offer for developers a packaged .exe (EXCEL) for that is
specific to our program so we can sell the user 1 package that would run our
program only?

Please help as i need to protect our investment

Unless you use a programming language other than VBA, you are stuck with the
built in protection systems of Excel and VBA. The average user will not be
able to get past your security if you have your code password protected. You
might be overly concerned at this point..

Thanks,

Does microsof offer a coverter from vba to machine lang?

Have a look at Chip Pearson's site on building a Com Add-in for greater security
and speed.

May be something you could try.

Hi Wade,

I find it a bit difficult to understand that you really invested 6 years of work and now started to think about protecting your
investment just before public launch.
What sort of information are you looking for?
