MS EXCEL (NEED HELP)
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 -- Wade |

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..

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? -- Kind regards, Niek Otten Microsoft MVP - Excel "Wade" wrote in message ... | We have a very extensive application that requires the use of Ms excel to | run.
