To connect to facebook from code , u need to lunch their login window in a webcontrol and handle the proper events .
Take a look in the following link : http://wiki.developers.facebook.com/index.php/Authorization_and_Authentication_for_Desktop_Applications Above code is written , most probably Mac OSx in mind. But it's the coding style that is important. But most importantly , you need to have a developer specific API key , which will be used for tracking and house-keeping (internally). Please do register in the parent site and get your key. [Same procedure as symbion development]. Good luck!
