Visual Basic - autocompletar una cadena

Sere breve:
Como logro autocompletar un texto que ya habia escrito anteriormente en una caja de texto, similar a lo que hace el explorer con las cuando escribes por segunda ocacion una pagina.

Gracias

El siguiente codigo lo saqué de VBCode, pero nunca lo probé, así que adelante, dame las novedades. Gracias.
