To do this, I put a listbox control on a form containing a listView control. Set the listbox visible property to False, then use this..
[vb]
Private Sub ListView1_MouseDown(Button As Integer, Shift As Integer, x As Single, y As Single)
If Button = vbRightButton Then
List1.AddItem ListView1.SelectedItem
List1.Visible = True
End If
[/vb]
