When you Declare 'Dim' waa as a 'New' 'WebBrowser' its name is waa
if you need 10 WebBrowsers Declare them all at once and you can use them at the same time...

Code:
        Dim Waa As New WebBrowser
        Dim Ele As New HtmlElement
        Waa.Navigate("http://www.yahoo.com")
        Ele = Waa.Document.GetElementById("id-name")
        Me.RichTextBox1.Text = Waa.DocumentText
