Connect my XBOX gamepad to the MT4

I need to create a few buttons shortcuts from my XBOX gamepad, so when I click a button from XBOX it will execute some actions, for example Buy trade with predefined lot.

All I need is for you to connect the XBOX gamepad to my mt4, because for example when I click on button B from my PC keyboard I can read that it has id 66 for lparam sent to OnChartEvent

but when I click any of the buttons from my XBOX there is nothing coming to my MT4 to the OnChartEvent function

here is an example of how it was done

I will need also the source code so I can change when I need something
