But how to I "weave" the SDK and the algorithms IN VC++?
I am only wondering if this idea of an autofocusing lego cam is feasible.
One day I may learn enough VC++ to be able to acomplish this project :-)
I'm glad to know there is hope!

| (...) If you download the SDK you will also get some demo programs. They will run with VC++ and show how to get a video stream to a window and how to use the motion detection feature of the camera driver. The demos don't help much for Kylix/Linux (...)
