i'd avoid the kludge of using a browser in an "automated" solution. you can
post data directly to the website using the httpwebrequest/httpwebresponse
classes in .net. you'd also probably need the httputility to encode the xml
before posting it (this depends though). anyway, those are the keywords for
you to lookup either in help or google. it only takes about 10 lines of code
to cleanly handle the post and response and there are plenty of examples on
the net.
