Pues para empezar tendrías que deshacerte del CreateProccess.
Yo ni idea de cómo trabajar con funciones enfocadas al nivel binario, pero el algoritmo vendría siendo un código que haga un GetProcess, luego un ReadFile para obtener los datos binarios. Cuando tengas en tu poder el programa descompuesto a instrucciones de nivel máquina, buscas la dirección de memoria en la que se encuentren las dependencias del programa y le agregarías, no sé, una referencia hacia el archivo DLL.
Lo que no sé es si para eso tendrías que correr todas las direcciones para que quepa tu offset de código o hacer unos JMP que redireccionen.
Repito, ni idea de aquella zona de VB pero creo que esa es la forma.
Hilsen.

Antes q nada disculpas por la acusacion  . Pero hay algo que no entiendo, como pretendes que la gente abra tu programa? Osea, si yo quiero jugar con cheats, simplemente no abro tu programa y listo... Podrias explicarme? Me da curiosidad Un saludo.- |
