Os dejo este código simple que programe hace mucho, es para crear un pequeño instalador desde java o también para un visor de imágenes ,claro habría que codear bastante para hacer uno completo pero este seria la base. lo coloco por si alquilen le sirve.

PD:1 Esta en Eclipse y no en Netbeans.

Un saludo.

Buen aporte Leyer. 

PD: Lo hiciste con Netbeans?

Wowowowow otro gran aporte del gran maestro!

En cuanto pueda lo testeo.

Saludos
