Yeah, I kinda glanced at that. By that point though, I was already feeling like there was enough bloat on both sides. I realized that because I had to have that ActiveX object to capture the state of the game controller, I could just add the bits I needed there to do plain old tcp socket communication with the arduino. If anything changes on the controller, it's current state gets sent off to the arduino while still in the Activex dll. The arduino forms a response and sends it back to the dll and then it gets returned to my javascript.
