How to log out of Facebook without any dialog box popping up?

Question

Every time I try to programatically logout of Facebook from my application I get a dialog box saying Logged in using Facebook and gives me only two option and those are logout and cancel. I want to get rid of this dialog box and do the logout in background. I can not figure out how to do this. Some one please help me in this.
