Save-As Restriction
 

Hi,
I have a database on sharing to different users, some with read+write rights
and some with only read-only.
I want to restrict all users specially with read-only permission that they
cant save the workbook on their desktop through "Save As" command. Workbooks
have important info which is required to be confidentials from external
persons.
Is there anyway that wrokbook cant be "save-as" on other workstations.
Regards
