win32 c++ set window 位置到右下角

win32 c++ set window location to the right-down corner

如何设置window到屏幕右下角(不包括任务栏)?我可以用 CreateWindowEx 完成吗?但是我只看到了CW_USEDEFAULT并没有CW_设置到角落里

HWND hwnd = CreateWindowEx(
            NULL,
            DUCKPROC_CLASS_NAME,
            DUCKPROC_WINDOW_TIP_NAME,
            WS_BORDER| WS_VISIBLE,
            CW_USEDEFAULT,
            CW_USEDEFAULT, 
            CW_USEDEFAULT,
            CW_USEDEFAULT,
            NULL,
            NULL,
            GetModuleHandle(NULL),
            NULL
        );

这是将 window 放在右下角的示例。 (这里我设置window的宽高都是200。)

   RECT desktopRect;
   if (!GetWindowRect(GetDesktopWindow(), &desktopRect))
       return FALSE;

   int windowWidth = 200;
   int windowHeight = 200;
   int posX = desktopRect.right - windowWidth;
   int posY = desktopRect.bottom - windowHeight;
   HWND hWnd = CreateWindow(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW,
       posX, posY, windowWidth, windowHeight, nullptr, nullptr, hInstance, nullptr);

您可以使用 CreateWindowEx,但您不必这样做,因为:

Creates an overlapped, pop-up, or child window with an extended window style; otherwise, this function is identical to the CreateWindow function.
