Buenas gente de indetectables

Les queria preguntar una cosita, estoy seguro que me podran ayudar...

Estoy armando algo simple en vb6.0 y me gustaria poner un formulario sin el fondo, osea que si pongo un boton se vea "en el aire" y atras se muestre lo que hay de fondo...ya sea el escritorio o lo que tenga detras del form...

se entendio? ::)

saludos y gracias de antemano
