在Duilib的Win32程序中，响应托盘消息在HandleCustomMessage函数中坐处理。

     NOTIFYICONDATA m_nid;//托盘

    m_nid.cbSize = sizeof(m_nid);
    m_nid.hWnd = /*this->m_hWnd*/NULL;
    m_nid.uID = ;
    m_nid.uFlags = NIF_ICON | NIF_MESSAGE | NIF_TIP |NIF_INFO; //NIF_INFO这个标识设置才会出气泡
    //m_nid.hIcon = sfi.hIcon;
    m_nid.hIcon = LoadIcon(CPaintManagerUI::GetInstance(),MAKEINTRESOURCE(IDI_ICON));
    m_nid.uCallbackMessage = WM_TRAYNOTIFYICON;
    m_nid.dwInfoFlags=NIIF_ERROR;
    m_nid.uTimeout = ;
    //StrCpy(m_nid.szTip, _T("佰卓云盾保护你的隐私安全"));
    StrCpy(m_nid.szInfo, _T("后台监控中..."));//气泡信息
    StrCpy(m_nid.szInfoTitle, _T("USB sensor"));

    ::Shell_NotifyIcon(NIM_ADD, &m_nid);
