Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        ' Part 1: Use WebBrowser control to load web page
        WebBrowser1.Navigate("http://www.locationary.com")
    End Sub

    Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
        ' Part 2: Username and password
        Dim theElementCollection As HtmlElementCollection
        theElementCollection = WebBrowser1.Document.GetElementsByTagName("input")
        For Each curElement As HtmlElement In theElementCollection
            Dim controlName As String = curElement.GetAttribute("name").ToString
            If controlName = "inUserName" Then
                curElement.SetAttribute("Value", "myUsername")
            ElseIf controlName = "inUserPass" Then
                curElement.SetAttribute("Value", "myPassword")
            End If
        Next
        WebBrowser1.Document.GetElementById("login@DEFAULT").InvokeMember("click")
    End Sub
End Class

Everything works fine except the login, it gives me an "Object reference not set to an instance of an object" error.
