VB.Net System.Net - Cookies - Form Submit

[IonutZ]

Hi guys,

This is what I'm trying to achieve:

• Login to Facebook via system.net

I've already achieved login through AxWebBrowser... but then I don't know how to disable sound / images / javascript and I occasionally get a JS error which is not cool...

But via System.NET I don't know how to work with cookies... This is what I've got so far (where I'm stuck)

Public Class Form1
    Dim web As New System.Net.WebClient()
    Dim james As New System.Net.Cookie
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 
        web.Headers.Add("Content-Type", "application/x-www-form-urlencoded")
        web.Headers.Add(Net.HttpRequestHeader.UserAgent, "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)")
 
        Dim d As Byte() = System.Text.Encoding.ASCII.GetBytes("email=[e-mail]")
 
        Dim res As Byte() = web.UploadData("https://login.facebook.com/login.php", "POST", d)
 
        txtCool.text = System.Text.Encoding.ASCII.GetString(res)
    End Sub
 
End Class
 

This is how the cookie IE7 makes, looks like:

*
 

This was much easier in VB 6, but I decided to step it up and try to do it in VB.Net...

What I don't know how to do:

• Add more variables to the post string

• How to show facebook through system.net that I "have cookies enabled"

• How to login haha

And as you can tell, [e-mail] is my e-mail... so if anyone could help, i'd be super-thankful.

The purpose of this program is - pure personal use, I want to make a program that checks for messages on facebook at a given interval of time and will warn me when I get one!

Thanks and looking forward to your reply!

I edited your post providing your email address in that format is a great way to get spammed.

Here is an article that may help:
ASP.NET Cookies

[IonutZ]

Nope, that doesn't really help because I'm trying to extract / emulate a cookie with the webclient .net component...

Thanks tho... anyone have any other ideas?

Here is a post trying to do something similar:
WebClient timeout

While this is not helpful either, I believe it illustrates a difference between VB6 & vb.net in trying to manage sessionstate for the project. In relation to webclient, I believe that there is class and not a component - unless you create one using the class. Here is an example:
Screen Scrapes in ASP.NET

So I don't believe that you can directly migrate a VB6 webclient component to asp.net the way that you would like. That is why the earlier article I referenced referred you to the handling of sessionstate through cookies. Here is an article that may prove me wrong:
Download a Web Page using the WebClient

I hope that this is helpful.
