Help? Stuck with my alerts program.

Hey,

I know most of you will just say, its easy your shit at coding but I need help with something.

I am trying to make a program in vb.net which when you open it it says if you got any alerts, this is the code atm, also is there a way to make it auto login from your browser saved passwords?

Code I got so far;

Code:
Imports System.Net
Public Class Form1

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

    End Sub

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim Client As New WebClient
        Dim Availability As String = Client.DownloadString("http://diversebox.net/")
        If Availability.Contains("Alerts (1)") Then
            Label1.Text = "yes"
        Else
            Label1.Text = " no"
        End If
    End Sub
End Class
