    Dim i As Integer = 0
    Dim a As Double = Val("@")

        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?

What part of the web page needs a random value? Is it that 'addition' question in there?

If yes, then that's been designed to not allow automated requests such as the one you're doing.

Yes, Its the addition question.
So you won't help me just because of that?

When you get the HTML of the page back, you'll need to parse it and look for the 'question', parse that, get the two numbers out, add them, and then enter that as the value for the textbox. That's as far as I'll go and besides, if you read their rules
