I have two suggestions:

1) Break your connect method into several functions/methods that 
correspond to the steps of the process of your logging in.

2) Rather than overriding PoseModally, override the dialog's Idle method 
and do the processing (of connecting) at Idle time.  You will probably need a
field variable to keep track of your connection state.  The main advantage
of this is that when the Cancel button is clicked,  IT can handle the process
of cancelling and you don't have to put a bunch of checks for this event into
your code.
