如何检查所需应用程序上的鼠标点击位置?

正如我们所知,目标屏幕手柄和点击光标位置的手柄:

// hWnd : Already known windows handle

GetCursorPos(&p);
HWND hWndFromPoint = WindowFromPoint(p);

// If the handle got from click point is child of the desire window means it is clicked on the desire window itself.
if (IsChild(hWnd, hWndFromPoint))
{
    // Do something on Mouse click 
}
