En esta libreria , que dejare debajo para que la puedan analizar, al yo colocar combinaciones de teclas, las ejecuta pero no suelta la primera tecla precionada, ejemplo: "CTRL+C" en este caso lo hace y copia pero , deja apretado la tecla CTRL.
Tampoco preciona la tecla WIN , que es fundamental para una cantidad de atajos en el teclado del sistema, espero puedan ayudarme.
En la libreria, existen dos modos de trabajo, uno que va dirigido a un proceso especifico y otro que va dirigido a la ventana activa.
En el metodo que va dirigido a un proceso se trabaja con esto:
private const UInt32 WM_KEYDOWN = 0x0100;
private const UInt32 WM_KEYUP = 0x0101;
y en el metodo que se trabaja con la ventana activa con esto:
private const int KEYEVENTF_KEYDOWN = 0x0001;
private const int KEYEVENTF_KEYUP = 0x0002;
espero alguien pueda porfavor explicarme la diferencia, y poder ayudarme a resolver este problema.
De antemano, gracias.
