Registrarse

[Victor-SB]

Buenas,

Si no recuerdan mal, a existido varias variantes de un virus antiguo que cuando te infectabas tu escritorio era cambiado por otro y cuando ibas a cambiar de fondo, veías que la pestaña Escritorio estaba eliminada, y me gustaría saber si alguien tiene su código, o si nadie lo tiene, me podrían dar una mano de cómo hacer que haga estas funciones con el S.O. Windows XP….
Es decir que el fondo escritorio actual se cambie por otro que quiera yo, al ejecutar el .exe sólo eso, no quiero que se elimine la pestaña de Escritorio, sólo quiero saber el comando de esta orden de que se cambie el fondo de escritorio por otro, una boludez, pero me gustaría saber que comandos eran =$

gracias

Usa las api y el registro...

[{_The_Alwar_}]

en el registro se guardan cosas del escritorio? ... jo cada dia se aprende algo

Para ocultar la pestaña de configuración del wallpaper lee sobre políticas del sistema, más exactamente sobre una llamada NoDispBackgroundPage

Funciones para manipular el registro utilizando la API

Para cambiar el wallpaper mira la función SystemParametersInfo, constante SPI_SETDESKWALLPAPER

Saludos.
