Hi,
There is no secure way of doing either of those things relying on Excel security, anyone with sufficient determination and Google will quickly remove all your passwords despite 'workbook open' and 'code module' passwords being more secure than workbook/worksheet.

Hi,
Perhaps this from Chip Pearson http://www.cpearson.com/excel/CreateAddIn.aspx Mike "SpeeD" wrote: Hi mike. Do you advise any software or have any solution for this?

Indeed, Excel's security, all all security for all Office components, is
pretty feeble. Access is ok, but still crackable if you know what you're doing. I've heard that .NET has very good security. I can't vouch for it though. I'm just now starting to learn it myself. As for your original question about Excel, quite simply no; it can't be protected with any degree of confidence.

Thank you all for your advice...
Perhaps with some other way besides strong and viseble security i can protect my work... Is there a way to hide procedures or any kind of code inside vba? some thought about that?? Any one with other ideas is welcome to say something!! :-) SpeeD "ryguy7272" wrote: Indeed, Excel's security, all all security for all Office components, is pretty feeble.
