| Pregunta: | 48451 - OBTENER NUMERO DE TARJETA ETHERNET O DE CUALQUIER INTEGRADO |
| Autor: | jorge nicora |
| agradecería si pueden indicar las pautas de como se puede escribir código en visual basic el cuál retorne el número de por ejemplo una tarjeta ethernet o de cualquier otra tarjeta o chip (sonido, video, etc.). No se si es a través de alguna api de windows o de algún código escrito en algún lenguaje de bajo nivel. Agradezco vuestra colaboración. | |
