Hi Guys

A new feature in our software requires that we screen scrape the NZ post website to give the functionality that is provided by their Post Code finder. I know that there have been some people trying to do such things in past years with getting post codes etc.

So far I have had no luck with sending some data to the form and getting a response.
I have tried the screen scraping example here:
http://www.worldofasp.net/tut/WebRequest/Working_with_HttpWebRequest_and_HttpWebResponse_in_ASPNET_114.aspx

But it doesn't seem to be able to send the form inputs to the URL: http://www.nzpost.co.nz/Cultures/en-NZ/OnlineTools/PostCodeFinder/

I think I am missing something big here with regards to how screen scraping works with the technology/techniques used for the NZ post postcode finder.

Basically what I am asking is, if anyone can see why I my attempt isn't working using that example and could give me some pointers?

Or even better if anyone has successfully screen scraped this page/knows someone who has or can give me a better way of doing it I would be very thankful.

Thanks
Liam
