Webrequest help

I trying to login a site from my vb app and it keeps saying login failed

Dim postData As String = "action=do_login&url=http%3A%2F%2FSITESIP%2F~soulvpsc%2Findex.php&quick_login=1&quick_username=" & TextBox1.Text & "&quick_password=" & TextBox2.Text & "&submit=Login&quick_remember=yes"
Dim bytes() As Byte = ASCIIEncoding.UTF8.GetBytes(postData)
Dim postReq As HttpWebRequest = WebRequest.Create("http://Sitesip/~soulvpsc/index.php")
postReq.Method = "POST"
postReq.KeepAlive = True
postReq.CookieContainer = mainCookie
postReq.ContentType = "application/x-www-form-urlencoded"
postReq.Referer = "http://SITEIP/~soulvpsc/index.php"
postReq.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13 ( .NET CLR 3.5.30729; .NET4.0E)"
postReq.ContentLength = bytes.Length
Dim postStream As Stream = postReq.GetRequestStream()
postStream.Write(bytes, 0, bytes.Length)
postStream.Close()
Dim postResponse As HttpWebResponse
postResponse = postReq.GetResponse()
mainCookie.Add(postResponse.Cookies)
Dim reader As New StreamReader(postResponse.GetResponseStream())
Dim strSource As String = reader.ReadToEnd
If strSource.Contains("Welcome," & TextBox1.Text & "!") Then
MessageBox.Show("Login Successful")
Else
MessageBox.Show("Login Failed")
End If

This looks as though you're trying to login to a MyBB forum correct?

You might read through the source and make sure that it's not asking you for a captcha. After a few failed attempts, it will ask for a captcha to prevent automated attempts such as this. In that case, it would not appear to be working.

because i dont want to post the link i trying to login to on here for every 1 to try an access

You don't have to post credentials at all... Just fake the data and let them know that you're not giving it out for confidentiality reasons. Simple, i'd never give anybody a login of mine if that's what the link contained for POST data or anything like that.

well it not a my bb site so idk how i would post it

[AceInfinity]

I didn't even really see the code you initially posted to be honest. You didn't use code tags... I'll see what KoBE responds to you first before making an attempt here.

Ok, I've looked at the site. I'm almost certain you are not sending the correct post data.

I can't test this out at work, but go through the steps of capturing the headers as layed out in this thread: http://tech.reboot.pro/showthread.php?tid=61

After that you will probably notice you need to modify this line:

Code: (SELECT ALL CODE)

Dim postData As String = "action=do_login&url=http%3A%2F%2FSITESIP%2F~soulvpsc%2Findex.php&quick_login=1&quick_username=" & TextBox1.Text & "&quick_password=" & TextBox2.Text & "&submit=Login&quick_remember=yes"

Ok, well I had a look now that I'm on my laptop w/ Live HTTP Headers.

All the post data you should be sending is:

Code: (SELECT ALL CODE)

username=user&password=pass
