Hi Guys: Wondering how I would bind VNAV switch to a joystick button, see how to bind it to a keyboard in FMC but not a joystick, thanks.

Bind it to a key and then set your joystick button to that key either in the stick's programming software or via FSUIPC.

Hi Ryan: I tried it with fsuipc but didnt work, I'll try again, maybe that key needs to be cleared out of fsx key assignments first ?

Use fsuipc to bind that button to a keystroke, then use the cdu to bind that keystroke to the command you want. Best to make sure that keystroke isn't used in default fsx commands.That's how I've been doing it.

Thanks Ken, have to try that, take care.
