Posting to web page form

[Kimmie]

Hi all.
I have programmed in C++, but I am new to VB. I have a question that feels silly, but I need to ask for your help.
I am writing an app that I want to navigate out to a web page (not showing it the user), get the form to create an account, then programmaticall y enter values into those form fields and Submit the form.
I think conceptually it should get the Form elements and pull them in, then I can cycle through them, filling in the info from my database...
Any ideas how to do this? You don't have to give me step by step code or anything - though I won't turn it down! ;)
Thanks, Gang.

Updated question. I am using a hidden WebBrowser to navigate to the page, then HTMLElements of a Form to check for attributes, etc -- my question now is

How can I fill in those form fields??
I can't figure out how to write to them then click Submit.

A thousand thank-yous...

OK, even more specifically: is there a way to write to the document in the webbrowser? If this is not possible with VB, is it possible to incorporate javascript into my project to handle it? If someone could just explain the finer points of this stuff to me I would really appreciate it.
Thanks for taking the time. :)
