Mover controles y ajustar tamaño en tiempo de ejecución

A cuantos nos ha pasado querer permitirle mover controles al usuario y que el usuario pueda cambiar el tamaño del objeto.

Esta utilidad muestra un ejemplo de ello, si quieren que se guarde esta información para que el usuario cargue las ventanas con las caracteristias que él a colocado, pues solo hagan una tabla en la que guarden el control y sus propiedades, en el Init del Form, carguen estas propiedades y en el Unload, guarden las nuevas.

Espero les sea de utilidad.
