C# 2005 Express - Browser App Problem

[JohnT]

Hello all,
Please excuse my ignorance, but I'm a newb.

I was creating my first windows form app as described in the help file. I'm
fairly certain that I entered everything as I was supposed to, but the
browser is not displaying anything but the standard IE error "The page cannot
be displayed". The app seems to be going forward & backward, but no web pages
are being displayed. I added full http paths to the list in the combo box. I
definitely added the initialization code to the form. Is there anything else
required to initialize the browser control? Code is attached below.
Thanks!!!
