Hi Gary,
This is in VB.NET but it should give you the idea.
Find out what the target page wants to see as far as field names and the
submit button. Put those values into the NameValueCollection. Upload that
using UploadValues and read the result.
You can call this routine on the click event of your own page. Just change
the URL and the form field names/values.
Sub DoPost()
Dim uriString As String = _
"http://p4320/p4320work/login.aspx"
' Create a new WebClient instance.
Dim myWebClient As New System.Net.WebClient
Dim myNameValueCollection As New _
System.Collections.Specialized.NameValueCollection
myNameValueCollection.Add("txtName", "Ken")
myNameValueCollection.Add("txtPwd", "password")
myNameValueCollection.Add("Button1", "")
Dim responseArray As Byte() = myWebClient.UploadValues _
(uriString, "POST", myNameValueCollection)
Label1.Text = "Response received was :" & _
System.Text.Encoding.ASCII.GetString(responseArray)
End Sub
