I think you posted that in the wrong forum. Try a web orientated forum next time. I will give you a hint though. You should use javascript and detect the screen height and width.

var w = screen.availWidth||screen.width
var h = screen.availHeight||screen.height
function full()
{
window.moveTo(0,0)
window.resizeTo(w,h)

}

window.onload=full


This is just some basic jscript code on changing the height and width to full screen. You would then put this in the body tag.
<body onload = "full()">

Hope this helps some.
