removing borders in windows mode

I have been searching the forums and found reference to Setwindowslong to remove the borders in windows mode, but to be honest I would not know where to start with this. Has anyone else set up windowed mode without the borders?

which borders ?

start windows borders?

when you open in window mode you get the blue window bar at the top with the minimisa, maximise and close.

I am now thinking I can't do what I wanted anyway, which was to use have dvi output on my nvidia card to the DVI input on my plasma and VGA to VGA on the same plasma then put the windowed XBMC onto one screen and have the other available for web etc....

I dont think it is possible to set up multiple monitors using one screen and two inputs.....
