Override Sound button of Qtek 1010

[onidre]

Hi,

I'm developing an application where i need to use the Sound volume button of Qtek 1010. So i need to disable his functionality and enable my code.
I can do it for the 2 upper buttons of Qtek. I've made some code to show me a window of the hardware code from every button i press, but in the sound volume button no window appears.

Can anyone help me ? Maybe the hardware code of the button helps ?

Thanks in advance
