Bueno, cómo ahora está de moda los numeros aleatorios encontré un hueco entre mis estudios y hice esto.
Soporta divrersos tipos de arrays...(Long, Byte, Integer...).
Uso la funcion de BlackZer0x (http://foro.elhacker.net/profiles/blackzerox961996199618961896179617-u59494.html) :

Tuve que cambiar un par de cosas nada más para adaptarlo.
