Manipulate/Change/Form Fill data in webpages using the Webbrowser control

[Mc_F]

I need something like that for VS 2003. As much as I like VS, I hate the way MS uses upward compatibility. Basically all I want to do is learn how to programmatically fill in fields on a webpage from within my application.

Here I am attempting a login attempt on a website. (username text box = edit_username)
So far:

Dim CookieContainer As New CookieContainer
Dim strPost As String = "edit_username=my_username&edit_password=my_password" 
Dim myWriter As StreamWriter
Dim objRequest As HttpWebRequest = CType(WebRequest.Create(uiURL.Text), HttpWebRequest)
Dim cookies As CookieContainer = New CookieContainer
  'objRequest.AllowWriteStreamBuffering = True
   objRequest.Method = "POST"
   objRequest.ContentType = "application/x-www-form-urlencoded"
   objRequest.CookieContainer = cookies
 
   myWriter = New StreamWriter(objRequest.GetRequestStream())
   myWriter.Write(strPost)
   myWriter.Close()
 
Dim objResponse As HttpWebResponse = CType(objRequest.GetResponse(), HttpWebResponse)
Dim str As StreamReader
   str = New StreamReader(objResponse.GetResponseStream)
   uiInfo.Text = str.ReadToEnd
   myWriter.Close()
 
   objRequest.GetResponse().Close()

Thanks.
