Visual Basic web browser w. tabs

[Master_script_maker]

Hi I am making a web browser in visual basic 2008(not "making", using web browser object). I need some help.
1. I would like a more efficient way of changing the url. I know there is i just can't find it.

Private Sub Go_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Go.Click
        TabControl1.SelectedTab.Controls.Clear()
        Dim wbr = New WebBrowser
        wbr.Name = "WebBrowser" + TabControl1.SelectedIndex.ToString
        wbr.Dock = DockStyle.Fill
        wbr.Navigate(ComboBox1.Text)
        wbr.ContextMenuStrip = Right_Menu
        TabControl1.SelectedTab.Tag = wbr.Name
        TabControl1.SelectedTab.Controls.Add(wbr)
    End Sub

2. For some reason the title does not display.

Private Sub NewTab_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NewTab.Click
        Dim wb = New WebBrowser
        Dim tb = New TabPage
        wb.Dock = DockStyle.Fill
        wb.ContextMenuStrip = Right_Menu
        wb.Name = "WebBrowser" + (TabControl1.TabCount + 1).ToString
        wb.Navigate("http://www.dynamicdrive.com")
        tb.Controls.Add(wb)
        tb.text = wb.DocumentTitle
        TabControl1.TabPages.Add(tb)
        TabControl1.SelectTab(TabControl1.TabCount - 1)
        If (TabControl1.TabCount = 2) Then
            DeleteTab.Enabled = True
        End If
    End Sub
