Securing Excel Workbook
Hi everybody
I made a set of internally & externally linked excell workbook, and I would like to prevent copying and distribution What is the best way to do so? Is it the rights managements? Is it enough? will it prevent copying the main excel files? Thanks for your time. A.El Tohamy |

Securing Excel Workbook
Are your users all ethical? If so, DRM may be enough. But then, you'd
just need to put a message in the workbook saying "don't copy or distribute". DRM will make it harder to transfer files, or to gain unauthorized access, but once users can open your workbook, there's really nothing that can be done to prevent them from copying everything in it, assuming they have the will and can scrounge enough neurons together to find these groups. You can do better by compiling your code in a COM add-in and doing some sort of check within it to make sure the user/machine/network is authorized.

Securing Excel Workbook
Dear Mr. McGimpsey,
Thank you very much for your reply I think users are not ethical every where, and I do not want to risk that someone take my efforts or just copy it and simply distribute it. Meanwhile can you advise how can I proceed with this COM add-in? "JE McGimpsey" wrote: Are your users all ethical? If so, DRM may be enough.
