Need helpwith rightclick menus

how to make the menu and how to make it right-click displayable at only certain locations?
I've tried to figure it out myself, but haven't got too far with that ideology. However, i'll present you my thoughts:
menuwith contextmenu

Code:

---

Private Sub ContextMenuStrip1_Opening(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles ContextMenuStrip1.Opening       
 TopLevelControl.Visible = False    End Sub

---

and right click

Code:

---

Private Sub BookmarkToolStripMenuItem__rightclick(ByVal Button As Integer, ByVal Shift As Integer, ByVal X As Single, ByVal Y As Single)
  PopupEventArgs()

---

something at least similar?
