Good morning,

Do you have any ideas as for securing a workbook based upon userid. I
believe each computer contains a API, MPR or DLL file which the current user
of that machines userid resides. I would like to be able limit access to
workbook based upon userid listed within the workbook.

Reason, the file contains sensitive information but needs to be accesible to
many. So, if someone who has rights to the folder saves the file and shares
it with someone else. That someone else will not have acces to the file with
out me specifying them somewhere in the VBA code or WB.

Is this possible?
