Setting a date for a workbook to expire
im putting together a workbook that i use to track performance of staff.
i want to code in somehow a future expiry date so that it can no longer be used. this is to prevent others from coping my hard work in design etc. and just use it for their own benifit if they were to leave or move to a competitor. |

Setting a date for a workbook to expire
Hi Dave !!
you could write a workbook-open event procedure that colours all the sheets in your workbook BLACK and also closes the workbook, on the 'expiry' date. That will do the trick !! But don't tell your employees how you did it !!

Dave !!
I forgot to tell you - you should put a password on your workbook - "Employee_Data" "dave.d71" wrote: im putting together a workbook that i use to track performance of staff. i want to code in somehow a future expiry date so that it can no longer be used. this is to prevent others from coping my hard work in design etc. and just use it for their own benifit if they were to leave or move to a competitor. |

Setting a date for a workbook to expire
ok you got my attention but how do you do this?
im not up to speed with macros etc, and rely on formulas in cells to do the job. is there an easy way to do this?

Setting a date for a workbook to expire
You could do it but it would require that users enable macros upon start up.
Also Excel's security is quite weak and users could crack passwords on the code to make the workbook "timebomb" itself. See Chip Pearson's site for a few methods of creating a self-destructing workbook. Note his caveats at beginning and the alternative of creating a Com add-in or similar. http://www.cpearson.com/excel/workbooktimebomb.aspx Gord Dibben MS Excel MVP On Wed, 4 Jun 2008 08:26:02 -0700, dave.d71 wrote: ok you got my attention but how do you do this? im not up to speed with macros etc, and rely on formulas in cells to do the job. is there an easy way to do this?
