Ver las unidades disponible en la Red

[jcl]

-----------------

[Loquillo_]

Claro que sí, y es muy fácil, usa el control CommonDialog de Microsoft y ponle un filtro para que sólo te lea unidades de red (que en realidad son direcciones de archivos lógicos y que luego las conviertes en unidades)

[Loquillo_]

Primero pega el control en un formulario x (preferentemente en el Principal que debe ser un MDI), luego, mediante codigo haz referencia a este control

With CommonDialog1
.filter = "*.*"
.open
.
.
.
end with

eso es todo.

Dame una dirección de correo para enviarte algo de codigo, creo que tengo algo parecido

Te paso un código (el cual no es mío) de como enumerar los recursos de red utilizando APIs:

Busca en http://www.lawebdelprogramador.com
De ahí yo saque el programa para ver las unidades de red, lamentablemente he perdido el programa, ya que no lo utilicé nunca

Espero que lo encuentres
y te sirva mucho
