[uniextra]

Hi there.. im sort of new posting, but not reading here!

I need help traying to log in to a forum to send a message on a given post.. but so far i just can't get loged in..

the code i have tried but does not work:

    Dim objHttp As Object    Dim URL As String
     
    Set objHttp = CreateObject("WinHttp.WinHttpRequest.5.1")


    ' SOLOCHOLLOS
        URL = "http://m.forocoches.com/foro/misc.php?do=page&template=ident"
        'vb_login_username
        'vb_login_password
    With objHttp
        .Open "GET", URL, False
         'you can even get out into the WWW through a proxy
         '.setProxy 2, "<your proxy server>:<port>", ""
         '.setcredentials "<user>", "<password>", 1
        .SetRequestHeader "User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"
        .SetRequestHeader "Content-type", "application/x-www-form-urlencoded"
        .Send ("vb_login_username=USERNAME&vb_login_password=PASSWORD")
    End With
     ' If you want to see the result uncomment the following line
         Cells(1, 2).Value = objHttp.ResponseText

Any ideas on how i can proceed?

Many thanks!
