Would something like this work? (Assuming a control on the form called ListView1)
Private Sub ListView1\_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) \_
Handles ListView1.DoubleClick
'-- get the item selected following the double-click
Dim sel As ListViewItem
sel = ListView1.SelectedItems(0)
'-- display the selected item text
If Not (sel Is Nothing) Then
MessageBox.Show(sel.Text)
End If
End Sub
