How to get the number of digitizer input device?

  • Hello,
    For a project we are using both multiple digitizer input devices and single digitizer input device on one computer using a custom TUIO API.
    Depending on hte number of digitizer inputdevice the behaviour is different.

    The OS is Windwos 7. I cannot find a way to get the number of digitizer input.

    As far as I know GetSystemMetrics only tells me that I have some but not how many.

    So how can I get the numbers of digitizer input?

    Thancks a lot
