Re: ASP.Net Page that has a control to display HTML

I got it.

It turns out that loading the page into my application was fine. The problem was that
the page was loading a cookie to automatically log me into my Yahoo account. It was
then posting back to my ASPX page to display which is what the r0=.... number is below.
Once I logged out of Yahoo the page displayed successfully.

I still don't know about using End().

Thanks all for the help.

Cheers,
Dave
