Holi Holas =)

Bueno, aca les dejo un modulito para emular la existencia de archivos, no esta 100% listo pero el ejemplo es totalmente funcional.

Lo que hace basicamente es redireccionar las APIs utilizadas para leer archivos engañando a nuestro programa para que lea desde la memoria.

El ejemplo muestra como usar LoadPicture para cara cargar un archivo BMP encryptado, desencryptandolo on the fly en memoria.

Muy buen code leandro, la verdad que se ven muy lindas las toolbars.

Vista viene con DirectX 10 asi que no se porque instalaste la version 8, calculo que con cambiar las referencias en el proyecto era mas que suficiente.

A ver si esto te ayuda

http://www.planetsourcecode.com/vb/scripts/ShowCode.asp?txtCodeId=14584&lngWId=1

En XP y 2000 funciona relativamente bien, en vista es nulo.

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Disk\Enum\0\]

@||MadAntrax||

Gracias por el comentario, se que es un poco extenso pero queria mantenerlo entendible y fiel al original.

Creo que el metodo mas simple para hacer esto es leer el valor de la clave HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Disk\Enum\0\   y compararla los los 3 patrones mencionados.
No lo probe con diferentes cuentas ni OSs pero por lo poco que vi funciona perfectamente.

Saludos y gracias por el feedback.


Edit:

Bueno Aca esta el codigo de la idea anterior

Para darte cuenta si se cerro del administrador de tareas podrias crear un archivo, clave en el registo o lo que quieras que se borre al finalizar la aplicacion normalmente AKA unload event, y si por algun motivo la aplicacion se termino desde el administrador o algo asi al reiniciarla en el load tendrias que ver que ese archivo o clave del registro existe

En vista con cuenta de invitado obtengo un esto al intentar conectar WMI (error 70: Permission Denied)

Si, el fin del codigo es el mismo, si miras el titulo dice NO WMI (Windows Management Instrumentation), lo hice asi porque como comente en el post original de MadAntrax, tube problemas con WMI y cuentas restringidas.

Bueno aca va mi humilde aporte, es una implemetacion del codigo de MadAntrax sin utilizar WMI, le agregue una funcion mas para detectar Sun VirtualBox.
