    Okay, I fixed it. Take out our BeginPaint and EndPaint from your RenderScene function. Move those functions to WM_PAINT message. All you need to do in that message is beginpaint and then immediately endpaint. It's important so do it. Then your RenderScene should look like this:

    Code:
    VOID RenderScenery( )
    {
     DisplayBitmap(GetDC(WIN_HANDLE), bRect, 0, 0, 50, 50);
    }
    Good luck.

    You should call ReleaseDC before you return from the function.
    Code:
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
    {
        return std::pow
        (
            std::complex<float>(std::exp(1.0)), 
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;
    }
