Script to Disable Right Click for Form

Script to Disable Right Click for Form

My users are circumventing the input form by right clicking on the form to get the url address then going straight to the database. This defeats the purpose of the database. Is there a script I can add to the form to disable the right click function? To understand what I am talking about please go to my website ( http://www.autovinvent.com/vindatabase/) and right click on the form, select properties and you will see the url for the database. Thanks in advance for any help.
