title: How to call a Web Page an automatically fill up a Form passing a String
body: <p>I use asp.net 4 c sharp.</p>
  
  <p>I would like populate a input text form with a string sent by an User.</p>
  
  <p>The destination page is:
  <a href="http://www.maxmind.com/app/locate_demo_ip" rel="nofollow">http://www.maxmind.com/app/locate_demo_ip</a></p>
  
  <p><em>NOTE: im not the developer for the target page.</em></p>
  
  <p>Here ho should work:</p>
  
  <p>When a visitor from my site click a link (Ip address)
  it will be sent to: <a href="http://www.maxmind.com/app/locate_demo_ip" rel="nofollow">http://www.maxmind.com/app/locate_demo_ip</a>
  and the TextBox automatically populates with the value (Ip address the user has clicked).</p>
  
  <p>The user Will manually click the button "Look Up IP addresses" in maxmind.com to have the result.</p>
  
  <p>Any idea how to do it? Maybe a sample of code?
  Thanks guys as usual for your great support! :-)</p>
