Keyboard Hooker in Visual Studio 2012 for making a Grasshopper component

Hello all

I am trying to make a Keyboard Readerfor Grasshopper using Visual Studio, based on George Mamaladze's KeyboardReader Component. Thing is, the bubble is made and Grasshopper recognizes it. But when a key is pressed, it is passed to Rhinocero's command line instead of being recognized by the Keyboard Reader. Can someone tell me how can I correct this? Below I am attaching the code.

Thank you very much
