Navigate to website in internet explorer

Hello,

I'm trying to create a app which I can store my usernames and passwords, and be able to navigate to that website using internet explorer, enter credentials and hit login. So far I've achieved this code however, it's using the webbrowser control in vb.net. can anyone help me with this code to use internet explorer.

   
Private Sub Login_Click(sender As Object, e As EventArgs) Handles Login.Click

        'Enter credencials
        WebBrowser1.Document.GetElementById("userid").SetAttribute("value", Username.Text)
        WebBrowser1.Document.GetElementById("pass").SetAttribute("value", Password.Text)

        WebBrowser1.Document.GetElementById("sgnBt").InvokeMember("Click")
    End Sub

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        'Navigate to webiste
        WebBrowser1.Navigate("https://signin.ebay.co.uk/ws/eBayISAPI.dll?SignIn")
    End Sub
