Thats the error code I got.

How do I fix this problem? This is the only piece of code that is causing problems, the rest of the code is fine trust me.

Public Sub CheckProxies(ByVal TheProxyArray As ArrayList, ByVal threadid As String)

        For i = 0 To TheProxyArray.Count - 1
            Try
                Dim Newproxy As String = TheProxyArray.Item(i).ToString
                Dim host As String = Newproxy.Remove(Newproxy.IndexOf(":"))
                Dim port As Integer = (Newproxy.Remove(0, (Newproxy.IndexOf(":") + ":".Length)))
                Dim PR As New Net.WebProxy(host, port)
                Dim URL As String = "https://offenceappeal.runescape.com/lang/en/aff/runescape/login.ws?username=Zezima&password=ImGay&dest=viewoffencehistory.ws"
                Dim Request As Net.WebRequest = Net.WebRequest.Create(URL)
                Dim Response As Net.WebResponse = Request.GetResponse
                Dim Reader As New IO.StreamReader(Response.GetResponseStream)
                tries = tries + 1
                Request.Timeout = Integer.Parse(TimeOutString)
                Request.Proxy = PR
                Source = Reader.ReadToEnd
                Reader.Close()
                Response.Close()
            Catch Exc As Net.WebException
                If (Source.IndexOf("Invalid Username or password" > -1)) Then
                    Status = "Working Proxy!"
                    WorkingArray.Add(TheProxyArray.Item(i))
                ElseIf (Source.IndexOf("Login Blocked" > -1)) Then
                    Status = "Working Proxy!"
                    WorkingArray.Add(TheProxyArray.Item(i))
                ElseIf (Source.IndexOf("You are logged in as" > -1)) Then
                    Status = "Working Proxy!"
                    WorkingArray.Add(TheProxyArray.Item(i))
                ElseIf (Source.IndexOf("Working" > -1)) Then
                    Status = "Working Proxy!"
                    WorkingArray.Add(TheProxyArray.Item(i))
                ElseIf (Source.IndexOf("" > -1)) Then
                    Status = "Bad Proxy Or Timed-Out or Not Compatible With RuneScape"
                End If
                Console.WriteLine("Thread #" + threadid + " Checking Proxy: " + TheProxyArray.Item(i) + " Result: " + Status)
            End Try
        Next i
        Console.WriteLine("Done Checking Proxies To See If They're Working!")
    End Sub

I don't know what the line numbers you posted means, but you set properties for Request variable after the webrequest has been submitted so it must be the "Request.Timeout =" line. It's too late to change the request at this time when it was submitted with your GetResponse call.

Hey, thanks John, I just changed the position of the timeout part right under where i declare request and now it works. Thanks a buch.
