How to register a "Boss Key"

Hi all,

Does anyone know how to implement a Boss Key? I want to register a global (operating system) shortcut (e.g. Alt + Ctrl + F10 )for reacting with my code regardless the game window is hidden ,Minimized, una-active , just like the unreal editor shortcut for LiveCoding (Alt + Ctrl + F11 ).

I have tried a console app that worked as intent :

#include <iostream>
#include <windows.h>

int   main(
    int argc,
    TCHAR* argv[])
{
    if (RegisterHotKey(
        NULL,
        1,   // id: 0x0000 ~ 0xBFFF for app,   0xC000 ~ 0xFFFF for dll ,
        MOD_ALT | MOD_CONTROL | MOD_NOREPEAT, 
        0x70))  //0x70 is 'F10'
    {
         std::cout << ( "Hotkey 'ALT+Ctrl+F10' registered, using MOD_NOREPEAT flag.\n");
   
    }

    MSG msg = { 0 };
    while (GetMessage(&msg, NULL, 0, 0) != 0)
    {
        if (msg.message == WM_HOTKEY)
        { 
            std::cout << ("WM_HOTKEY received!!\n");
        }
    }

    return 0;
}

I have tried all RegisterHotKey() in my c++ code and I could register this hotkey successfully ,
but I don’t know where to place the GetMessage() method for polling WM_HOTKEY event from the main game message loop (game thread).

Is my approach wrong or is there another way to implement this functionality?

thanks
