Secrecy in Excel

Dear People...

I have broke my back trying to develop a little utility for the court i´m a Judge, only to witness in horror as a fellow Judge tried to browse through it via a LAN i Installed with my very own resources. That scourge even had the nerve to bring a notepad to take note of the formulae that CELIA gave me!!!!!
Is there any way to protect those formulae????. is there a way to display my copyright on the worksheet? Perhaps as a Macro?????

One way to prevent this from happening is to password protect your workbook that contains the formulas/macros. What's nice about it is that the user is prompted for the password BEFORE the workbook is opened - thereby preventing access entirely. Depending on how much of a "hacker" your fellow user is it should prevent access nicely.

To put a password in place, go to Tools>Protection>Protect Workbook. Select your own password and that should do it.

If you just want to hide the formulas from potential plagiarists, have a look at "Hide or Unhide Formulas" in on-line Help. You would also probably need to prevent access in some way since the nefarious judge(s) may know how to unhide the formulas.
There are many ways to protect your workbook.
For instance, you can password protect the workbook or worksheet; prevent changes to specified cells; put your formulas in a hidden non-accessible row or column and only show the result of the formulas in the cells that require the results (or even have the formulas in a different non-accessible worksheet), et cetera.

Look up on-line Help dependant upon what you would like to do.
Post again if you run into difficulties.
