IE OnResize Scripting

I ran into some ugliness recently setting an iFrame height dynamically where the script would run away on IE.  I found the answer at http://stackoverflow.com/questions/1500312/javascript-onresize-event, posted by Pim Jager.  The resulting combination of the resize and his event handling is as follows:

function getDocHeight()
{
var D = document;
return Math.max(
Math.max(D.body.scrollHeight, D.documentElement.scrollHeight),
Math.max(D.body.offsetHeight, D.documentElement.offsetHeight),
Math.max(D.body.clientHeight, D.documentElement.clientHeight));
}

function setIframeHeight(frameId, offset)
{
document.getElementById(frameId).height = (getDocHeight()-offset)+'px';
}

var resizeIframeTimeOut = null;

var func = function() {setIframeHeight('boInfoViewIframe', 150);};

window.onresize = function(){
if(resizeIframeTimeOut != null) clearTimeout(resizeIframeTimeOut);
setTimeout(func, 100);
};

setIframeHeight('boInfoViewIframe', 150);

One note about resizing elements is that IE will resize again if your new size causes the document size to grow. That was a two hour lesson for me :)
