Hi Kevin,

This is half of what I want to do. Let me give you some additional
background on what I am doing. I am building a website that is the primary
user interface for my company's products. To give our clients the best
possible experience using our product, we have enriched each of the website
pages with client-side script in form of DHTML Behaviors. These scripts
perform various tasks such as building HTML Tables, calling webservices, and
posting back collected data via XMLHTTP. So far, the site with the script
works fairly well, but the script is extremely slow and cumbersome to work
with. There are also memory leak issues caused by they way the scripting
engine interacts with MSHTML. So while using script is possible, it is not
very desirable.

What I want to do, is to replace some (if not all) of the script with a .NET
component. I want this component to be created and hosted by IE through the
<object> tag in such a way that I do not have to request .NET permissions
other than those granted by default to components running in the "Internet
Zone." Once the component represented by the <object> tag is loaded, I'm
going to want it to make changes to its containing HTML DOM in order to
render HTML tables and do all those things I do in script now.

So far I have written a test component and loaded it into a test HTML
document, but I don't know how to get a reference to the containing
document.

Your help in the matter is very appreciated.
Wells
