Is this your own site or someone elses? and how are you opening it?

create a POST request to the http://www.example.com/login.php

and that will do it for you.


Basically, you would need to do the following:
1. create a HttpWebRequest object and use HttpWebRequest.Method = "POST".
2. set the Post data to contain your data (username and password).
3. "Post" (i.e. execute and get the response for) the HttpWebRequest.

and you will face cookie not enabled issue, so make sure you enable it as described first line in the code below...

CookieContainer cookies = new CookieContainer();
HttpWebRequest postRequest = (HttpWebRequest)WebRequest.Create(site);
postRequest.CookieContainer = cookies; // note this
postRequest.Method = "POST";
postRequest.ContentType = "application/x-www-form-urlencoded";
using (Stream stream = postRequest.GetRequestStream())
    stream.Write(buffer, 0, buffer.Length);

good luck!

Using IWebBrowser2 is a good idea to do this task.

Thanks all for your suggestions. Have figured this one out myself now though.

here's how I did it.
If (WebBrowser1.Document.All("username") IsNot Nothing) And (WebBrowser1.Document.All("password") IsNot Nothing) Then
            WebBrowser1.Document.All("username").SetAttribute("value", "username")
            WebBrowser1.Document.All("password").SetAttribute("value", "password")
            For Each element As HtmlElement In WebBrowser1.Document.Body.All
                If element.Name = "submit" Then
                    If element.GetAttribute("value") = "Login" Then
                    End If
                End If
        End If
