Check stylus barrel button state when hovering

Question

if there is any notification in metro apps like "WM_PointerUpdate"...

I want to check the barrel button is pressed when hover and keep update the state.

But the Event "Pointer_Entered" is triggered only once before the "Pointer_Exited"

to get the barrel button event.

Thanks for reply.

But I need to detect & update the button state when Hover , not yet pressed or move.

For example, When the pen is hover, I would like to pop a dialog when the barrel button is pressed

But I don't know where to get the button event update because the "Pointer_Entered" is not coming again
