title: Passing parameters to a website
body: <p>Well, I'm a complete stranger to this topic; I don't even know the general name of this kind of operation, but I'm going to try to explain it. (it's probably something pretty basic)</p>
  
  <p>I'm trying to write a auto-form-fill application. In order to have an interface planning to use GUI on VisualStudio.</p>
  
  <p>It is simply some text boxes that are similar to web site's registration form and a register button to initialize the action.</p>
  
  <p>The information that the user enters in those text boxes will be sent to similar text boxes on a predetermined website's registration page.
  Then when I click the register button on my application, it will also click the register button on the webpage.</p>
  
  <p>This is simply what I'm trying to do. How can I start? Which topics should I read up on?</p>
  
  <p>Thanks in advance.</p>
