hola amigos alguien podria decirme la forma de hacer que mi programa no salga en la lista del administrador de tareas??
Entiendo que tiene que ser un proceso pero no se como hacerlo, gracias a todos de antemano :D

Aqui lo tienes:


Saludos.  ;D

eso no esconde el proceso... ;) ;) ;)

Si te interesa busca un manual de Zealot de como ocutlar proceso en el taskmngr sin hooks.

Salu2

Eso esconde la aplicacion de la lista de tareas....Pero me imagine que era lo que pedia... Si quieres esconder el proceso hay api's para poder conseguirlo.

saludos.

No te olvides de olcultar el formulario en un sub main o en el evento form_load

gracias por responderme, quiza no me explique bien, lo que yo quiero hacer es un programa de control para un cibercafe, ovbiamente el usuario no deberia poder apagarlo, voy a revisar el manual que me recomendaron, ya les contare de mis pesquisas  :rolleyes:

hombre, puedes bloquear el administrador de tareas para que no salga

Muchas gracias por tu respuesta Soru13 le has dado un empujon tremendo a mi duda, voy a aplicar tu metodo inmediatamente en mis programas. ;D
Aunque a un sigo buscando la manera de ocultar mi programa del task..  :P

Bueno despues de estar buceando por horas en la web encontre este codigo, a mi me ha funcionado para ocultar mi programa del task... lo pongo aqui por si a alguien le interesa el asunto.

En un modulo

Sería bueno que pusieras la fuente de donde sacaste eso por que se parece mucho o se me hace que este code lo vi en algun lado.

Saludos.
