Hi,


I've made an Excel program and would like to have that after a certain date
is becomes totally un-usable for the users. I thaught of putting in te open
workbook for example a check with that specific date and close the workbook.
But if you do not enable the macros, it will be possible to get into the
code and remove this code.

Is there another and for sure better way to do this. Like erasing part of
the code, and that it cannot be traced easily?


thanks a lot in advance,

Yves
