The Thinker
anyone know how to send multiple mouse messages?
Anyone learned how to get multipoint or mousemischief to work with rawinput by simulating a certain amount of devices being plugged up or having rawinput sent to an emulated device? Right now i wish to implement multiple mice into my kinect project but need to know the correct input report or how to use raw input with multiple mice. kinect project page: http://kinectmultipoint.codeplex.com
