Here's a javascript function I use to dynamically resize an IFrame from 
within the IFrame...

function resizeIFrame(w)
{
  if (parent.document.location != document.location)
  {
    var oFrame = parent.document.getElementById("customFrame");
    if (typeof(oFrame) == 'object')
    {
      oFrame.style.width = (document.body.scrollWidth + w);
      oFrame.style.height = (document.body.scrollHeight + w);
    }
  }
}

I use it because I'm generating content on the fly in javascript on the 
client, and I want the IFrame containing the content to be a close fit.

There's a test in there to make sure the code running is within a child 
document and that there is actually an IFrame object named "customFrame" 
before it tries to change the size.

When I try this out using a container and child on the same machine all is 
well. It also works when the document is not in an IFrame and when the 
parent has no IFrame named "customFrame".

When the IFrame content is on a different server to the parent I get an 
error "Access denied" when I try to test the parent.document.location to 
see if it's the same as the running document.

Unfortunately this is exactly where it will be used in a real deployment, 
so I need a fix.

Does anyone know how to get and set properties in the parent document when 
the parent and child are on different domains?
