How can I make a video go fullscreen using VBA??
Yes, but there is little easy about it, no such thing as a handy Full Screen
command. Your macro will have to dertermine what resolution and DPI you
machine is running at, make the required calculation based upon the physical
dimensions of the video, and then insert it onto the slide.
Will ascept ratios be correct?
That depends how good your calculations are. <g> In all probability, they
won't be a perfect match.
One more thing I will mention, if the video you start with is say 640 x 480
and you go full screen to say 1024 x 768, be prepared to experiance serious
degradation in what you see,
As a suggestion, why not use an extra slide, stretch the video to take up
the entire slide and then hyper link to it? No VBA required.
