Hi all,  I am coping/transffering items from listbox1 to listbox2.
how can I prevent coping/transffering item twice by code.  I want some
kind of code which popup message saying "You already have copied this
item" etc.  Please can any friend can help

Something like:

'untested
If Listbox2.Items.Contains _
(Listbox1.SelectedItem) = True Then
Msgbox("You have already added this to Listbox2!")
End If

When user selects any item in Listbox1 to add Listbox2, if item exists
already, Msgbox will appear.

HTH,
