Dual video Powerpoint and VB - help required

[JohnK]

Ok,
I have the code below and a form with two buttons. How can I change this to
show the PPT presentation on a secondary monitor. My system had a dual video
option an is settings are correct. PPT itself can play the show on the
second screen. But I'd like to do it by VB. I think I need some other
api-calls. Can someone help me? I'm a newbie in api.

TIA,
John
