Programación / .NET (C#, VB.NET, ASP) / (SOLUCIONADO) Duda sobre los elementos que trabajan en segundo plano
|
en: 17 Diciembre 2012, 09:14 am

Hola,
¿Cuales de estos elementos trabajan en segundo plano al llamarlos, y cuales NO (osea cuales congelan la class)?
Sub Function Module Una class distinta a la actual (No se me ocurren más elementos que preguntar...)
Por ejemplo un thread , all llamarlo trabaja en segundo plano sin congelar la app, pues a eso me refiero, ¿hay otros elementos que trabajen en segundo plano?
Muchas gracias

Me temo que sí, pero para eso existe la referencia de las "shell folders" en el registro de Windows lo cúal te ahorra toda la taréa: Reg query "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders" /V "desktop" Saludos

Las rutas que te dí son para Windows 7, son correctas, y son la única "variable" que puedes utilizar, En Windows XP como acabas de descubrir no puedes usar la referencia del nombre en Inglés como se hace en Windows 7, tienes que escribir el nombre tál cual está en el idioma dle SO ("Escritorio", "Menú inicio"). EDITO: Para Windows XP: "%USERPROFILE%\Menú Inicio\Programas\Inicio"
Saludos

La carpeta donde estan todos los programas que se ejecutan al abrirse la sesion del usuario ¿Quieres decir la carpeta de los programas del menú de inicio? %APPDATA%\Microsoft\Windows\Start Menu y: %PROGRAMDATA%\Microsoft\Windows\Start Menu Saludos

PD: Causas de porque no lo hago: Soy muy noob en PhotoShop. Y no lo tengo instalado Seazoux, cada pregunta tuya que véo es la leche... ¿Como piensas hacerlo si no te instalas Photoshop (u otro editor)? Estamos hablando de un degradado... no hace falta ciencia ni experiencia para hacerlo. Saludos.

Si tienes un equipo de 64 Bit, por lo que he leido es extremádamente dificil modificar las tablas de syscall (Pero no imposible), mis conocimientos no llegan a este nivel, y me ha sido imposible hallar la solución. Saludos

Yo no me preocuparía si se pierde, La idea la sigues teniendo en la cabeza, ponla en práctica usando C como pretendías hacerlo en un principio, PD: Porfavor no desviemos más el tema del problema de Windows
