[Tutorial] Easiest way to add a HackCommunity Login form to your application - ArcaneFx - 05-26-2012

I wanted to write this tutorial for a long time now, so here goes. :thumbs:

Alright, first off, add a new form to your WindowsFormsApplication and call it Login or whatever you want.

Now add two textboxes and one button. The first textbox for inputting the username and the second one for the password.
Change the button text to "Login".

Add the following code to button1:

Code:
Dim postData As String = "http%3A%2F%2Fhackcommunity.com%2Fmember.php?action=login&username=" + TextBox1.Text & "&password=" + TextBox2.Text & "&submit=Login&action=do_login&url="
        Dim tempcookies As New CookieContainer
        Dim encoding As New UTF8Encoding
        Dim byteData As Byte() = encoding.GetBytes(postData)
        Dim postreq As HttpWebRequest = DirectCast(HttpWebRequest.Create("http://www.hackcommunity.com/member.php?action=login"), HttpWebRequest)
        postreq.Method = "POST"
        postreq.KeepAlive = True
        postreq.CookieContainer = tempcookies
        postreq.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.1; ru; rv:1.9.2.3) Gecko/20100401 Firefox/4.0 (.NET CLR 3.5.30729"
        postreq.ContentType = "application/x-www-form-urlencoded"
        postreq.Referer = "http://www.hackcommunity.com/member.php?action=login"
        postreq.ContentLength = byteData.Length
        Dim postreqstream As Stream = postreq.GetRequestStream()
        postreqstream.Write(byteData, 0, byteData.Length)
        postreqstream.Close()
        Dim postresponse As HttpWebResponse
        postresponse = DirectCast(postreq.GetResponse, HttpWebResponse)
        tempcookies.Add(postresponse.Cookies)
        logincookie = tempcookies
        Dim postreqreader As New StreamReader(postresponse.GetResponseStream())
        Dim thepage As String = postreqreader.ReadToEnd
        If thepage.Contains("You have entered an invalid username/password combination.") = True Then
            MsgBox("Error logging in, try again!", 0, "Incorrect Username/password combination.")
        Else
            MsgBox("Account verified, you can now proceed to the beta key generator.", 0, "Logged in.")
            MAINFORM.Show()
            Me.Hide()
        End If

Replace the mainform with the name of your application's main form.

Don't forget your imports:

Code:
Imports System.Net
Imports System.Text
Imports System.IO

That's basically the end of the coding part.
Now click on Project Settings and change the default form to Login.vb.

You're done.

I just want to say thank you to the unknown user who taught me this method.

Goodluck and god speed. :bye:

That's not an issue with the code. You were either disconnected from the internet, or HC/Whichever MyBB forum you were trying this code out on was down at the time.

That unknown user that you copied most of the code from is here: http://howtostartprogramming.com/vb-net/vb-net-tutorial-51-httpwebrequest-post-method/

His username is Eleqtriq and can be found on HF(which pops up as google apparently).

Just some advice, it's probably more failsafe if you check to make sure that you're logged in by seeing if such parts of the logged in member source code exist, rather than checking for that invalid password message. Check for "UserCP" or something like that and you're good.
