大佬们，请问如何实现一个C语言的托盘程序（Windows系统）

添加托盘
    NOTIFYICONDATAW nd;
    nd.cbSize = sizeof(nd);
    nd.uFlags = NIF_ICON|NIF_MESSAGE|NIF_TIP;
    nd.hWnd = m_hWnd;
    nd.uID = IDR_MAINFRAME;
    nd.hIcon = m_hIcon;
    nd.uCallbackMessage = WM_TRAY;
    wcscpy( nd.szTip, L"这里是提示信息" );
    Shell_NotifyIconW( NIM_ADD, &nd );
WM_TRAY 是个自定义消息，比如我可以定义它为 #define WM_TRAY (WM_USER+1)

删除托盘
    NOTIFYICONDATA nd;
    nd.cbSize = sizeof(nd);
    nd.uFlags = NIF_ICON;
    nd.hWnd = m_hWnd;
    nd.uID = IDR_MAINFRAME;
    nd.hIcon = m_hIcon;
    Shell_NotifyIcon( NIM_DELETE, &nd );
