webbrowser getting random value

[hypermx]

Okay, so im making a register program for a website

http://sy1.no-ip.biz/register.php

So far i've managed to make this code:

Public Class Form1
    Dim generator As New Random
    Dim randomValue As Integer
    Dim i As Integer = 0
    Dim a As Double = Val("@")
    Dim com As Double = Val(".com")
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        WebBrowser1.Document.All("name").Focus()
        randomValue = generator.Next(99999, 999999)
        SendKeys.Send(randomValue)
        Timer1.Start()
    End Sub

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        If i = 0 Then
            WebBrowser1.Document.All("pass").Focus()
            randomValue = generator.Next(99999, 999999)
            SendKeys.Send(randomValue)
            i = 1
        ElseIf i = 1 Then
            WebBrowser1.Document.All("vpass").Focus()
            SendKeys.Send(randomValue)
            i = 2
        ElseIf i = 2 Then
            WebBrowser1.Document.All("email").Focus()
            randomValue = generator.Next(99999, 999999)
            SendKeys.Send(randomValue)
            SendKeys.Send("@")
            SendKeys.Send(randomValue)
            SendKeys.Send(".com")
            i = 3
        ElseIf i = 3 Then
            WebBrowser1.Document.All("dob").Focus()
            randomValue = generator.Next(1970, 2000)
            SendKeys.Send(randomValue)
            SendKeys.Send("-")
            randomValue = generator.Next(10, 12)
            SendKeys.Send(randomValue)
            SendKeys.Send("-")
            randomValue = generator.Next(10, 27)
            SendKeys.Send(randomValue)
            i = 4
        End If
    End Sub
End Class

But now i need to make a random value as the same on the webpage, Is that even possible when i don't have the script, but only the webpage?
