    GetGUIThreadInfo()

    Hello,

    In my application I am making a call to GetGUIThreadInfo() but it returns 0. After making a call to GetLastError() I see that it's returning 87; which hints to the fact that I am passing an incorrect parameter. Here is how I invoke it:
    Code:
        GUITHREADINFO info;
    char buff[256];
    info.cbSize = sizeof(GUITHREADINFO);

    GetGUIThreadInfo(GetCurrentThreadId(), &info);
    GetWindowText(info.hwndActive, buff, 256);
    printf("Current Window: %s\n", buff);
    The MSDN documentation indicates that the only thing required in order to let a call to GetGUIThreadInfo() function properly is setting the GUITHREADINFO's cbSize member to sizeof(GUITHREADINFO), which I am doing.

    What can be wrong?

    It worked fine on my system.
    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;
}

    Well, MSDN does say to use GetWindowThreadProcessId or NULL (to get the current process info), although I can't imagine why GetCurrentThreadId wouldn't work.
    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;
}
