Salve a tutti, ho trovato il seguente codice:

Inherits System.Windows.Forms.ListView
...

Private Const WM_HSCROLL As Integer = &H114
Private Const WM_VSCROLL As Integer = &H115

Protected Overrides Sub WndProc(ByRef msg As Message)
    ' Look for the WM_VSCROLL or the WM_HSCROLL messages.
    If ((msg.Msg = WM_VSCROLL) Or (msg.Msg = WM_HSCROLL)) Then
        ' Move focus to the ListView to cause ComboBox to lose focus.
        Me.Focus()
    End If

End If
    ' Pass message to default handler.
    MyBase.WndProc(msg)
End Sub

con il quale � possibile sapere quando viene fatto lo scroll orizzontare e
verticale.

Come faccio a sapere quando viene fatto il resize di una colonna ?

ma in generale esiste da qualche parte l'elenco delle costanti che �
possibile intercettare ?

grazie
