Hi,
I want to build an app (C#, windows app, or web app, shouldn't make a
difference) that submits an address to the canada post website's address
lookup and then scrape the postal code out of the resulting page. Here is
their page. http://www.canadapost.ca/tools/pcl/bin/advanced-e.asp It uses a
form post.
I would like a basic rundown of how to submit my own info into their results
page (post), and then scrape out the info I need.
Thanks,
Brent 4  2698 
1) use webclient class to call the website.
2) hit the page and view source to see what the input control names are
3) post the page with the values you want.
4) write code to parse the returning html for the values you want. a few reg
expressions ought to work.

in addition to Bruce's info, there is a tool (Fiddler) which is a
debugging proxy - it will capture all the HTTP traffic and allow you
to analyze it. This can be a great help when figuring out what you
need to POST. http://www.fiddlertool.com/fiddler/

Aside from your current approach if I were you I would also ask
canadapost.ca if they intend to expose the data using web services
as every time their page changes you may have to rebuild your scraper.

The problem is I have 3 buttons that need to submit the form to different
URL.
My approach is to declare <input type="submit"> rather than <input
type="button">.
And put the following in the JavaScript:
InputForm.action="URL LOCATION"
InputForm.method="POST";
I think we don't need InputForm.submit(); because <input type="submit">.

What i wanted to do is make a webgame easyer, by getting
the page, and in stead of having multiple click actions,
make it all just 1 click and record stats for my profile.
For Example:
there is an arm wrestle part, you have to select oponent,
and click Challenge, because of the high traffic, once
you click challenge, the match is allready over, and u
have to refresh the page and try another.
