Wrapper Clavier Souris sous DirectX en C#

Bonjour à tous,

Je suis en train de travailler sur un projet qui nécessite d'intercepter les touches du clavier, ainsi que celles de la souris lors je me trouve dans un jeu sous DirectX.
Je ne suis pas dans le jeu lui même, mais une application externe.

Mon application fonctionnait jusqu’à aujourd'hui via un Hook sous Windows que j'avais trouvé ici :

https://globalmousekeyhook.codeplex.com/

Mais cela ne fonctionne pas dès que je passe dans un jeu sous DirectX.

J'ai cherché longtemps avant de vous écrire. J'ai d'ailleurs trouvé sur internet un wrapper pour le Joystick. cela fonctionne très bien lorsque je rentre dans le jeu.
je veux donc pouvoir faire exactement la même chose mais pour le clavier et la souris.
je suis relativement novice, donc je compte sur vous pour m'aider ;)

je ne retrouve plus le lien mais voici le code de ce wrapper (c'est un peu long, désolé).

Code:

Bonjour,

Quelle bibliothèque/wrapper utilisez vous pour DirectX ?
Ne suffit t-il pas de l'utiliser normalement, pour obtenir ce que vous souhaitez faire ? Dans le sens, récupérer les événements et les traiter ?

J'ai réussi à faire ce que je voulez. J'envoi les commandes via SendInput.
J'ai donc constitué une classe qui gère cela dans mon appli.
Ceci dit pour tous les débutants comme moi, une petite classe toute faite serait un bon point de départ.
surtout parce que ce que j'ai fait je ne suis pas sur de l'avoir bien fait...

éventuellement, je partage pour que vous me disiez ce que vous en pensez.
d'ailleurs comment puis je gérer les combinaisons de touches ? par exemple : Ctrl + A

Code:
