问题遇到的现象和发生背景

问题相关代码，请勿粘贴截图

  private void Button_Click(object sender, RoutedEventArgs e)
    {
        int aaaa = (int)dt.Window;
        zb_总 =new zb_总();
        m_root_element= zb_总;
        m_root_element.Height = 100;
        m_root_element.Width = 100;
        HwndSourceParameters sourceParams = new HwndSourceParameters("00");
        sourceParams.PositionX = 0;
        sourceParams.PositionY = 0;
        //sourceParams.Height = 100;
        //sourceParams.Width = 100;
        sourceParams.ParentWindow = new IntPtr(aaaa);
        sourceParams.WindowStyle = 0x10000000 | 0x40000000; // WS_VISIBLE | WS_CHILD;  
                                                            // 创建 HwndSource 对象
        m_hwnd_source = new HwndSource(sourceParams);

        //设置根视觉
        m_hwnd_source.RootVisual = m_root_element;
        m_hwnd_source.SizeToContent = SizeToContent.WidthAndHeight;
        m_hwnd_source.AddHook(child_hwnd_source_hook);
    }

你好好看看这个，m_hwnd_source.AddHook(child_hwnd_source_hook); 这个有问题
