Contents
[ ]

Il seguente codice di esempio carica il file Excel di esempio che contiene un’immagine OLE non reale. L’oggetto OLE è effettivamente un documento di Microsoft Word ma il file Excel di esempio mostra l’immagine dell’animale invece dell’immagine di Microsoft Word. Ma se si apre il file Excel di output, si vedrà che Microsoft Excel mostra l’immagine OLE corretta.
