    count down from secs

    in a WIN32API program how would you count down from a certain number of seconds without delaying messages by using "sleep(int time)"

    Create a timer with SetTimer(HWND hwnd, int ID, int milliCycle);

    (I might have the last two params backwords)

    Anyway, set the milliSec duration to 1000, since that's a second...

    And be sure to kill the timer when your done with KillTimer(HWND hwnd, int ID);

    Oh yeah, do all you work in the case WM_TIMER switch...
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
        return std::pow
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;

    Watch the accuracy of timer msg's as they have the lowest priority in the cue.
