Question

So I have sent close to two hours searching for an answer but nothing is working. I need to to send a few cookies through my webbrowser object but for some reason the cookies aren’t being read by my PHP file:

<?php die('Your username is '.$_COOKIE['user']); ?>

And my VB code to send the cookies:

For i = 0 To 4
uploadBoxes(i).Navigate("about:blank")
uploadBoxes(i).Document.Cookie = "user=" & username.Text
uploadBoxes(i).Navigate("http://*****/uploader/app.php")
Next i

Again, any help would be appreciated and yes, I do need to send it over the webbrowser object. I also have browsed through MSDN database and even that has shed little light on this problem.

—————————————— THE ANSWER ————————————————-

So I took the InternetSetCookie method and came up with this code that worked on making the cookies:

Imports System.Runtime.InteropServices

   ' No more data is available.
    Const ERROR_NO_MORE_ITEMS = 259

    ' The data area passed to a system call is too small.
    Const ERROR_INSUFFICIENT_BUFFER = 122

    Private Declare Function InternetSetCookie Lib "wininet.dll" _
     Alias "InternetSetCookieA" _
     (ByVal lpszUrlName As String, _
     ByVal lpszCookieName As String, _
     ByVal lpszCookieData As String) As Boolean

Private sub something()
              Dim bRet As Boolean
                bRet = InternetSetCookie("http://*****/uploader/app.php", _
                 "user", "admin")
                If bRet = False Then
                    MsgBox("Failed")
                End If
                uploadBoxes(i).Navigate("http:/*****/uploader/app.php")
End sub

'`CookieCollection` was populated using HttpWebRequest/Response calls

InternetSetCookie("https://www.url.com/", Nothing, CookieCollection(i).ToString() & "; expires = Sun, 01-Jul-2014 00:00:00 GMT")
'repeat for however many cookies you've got

browser.Navigate("https://www.url.com/", True)
