WTL嵌入类的架构可以使整个程序很清晰，系统托盘气泡提示、上下文菜单处理可以分别独立出来，以下是实现代码，很清晰就不注释了。基本上这两个类很少需要修改，因此我把它们放到了系统包含文件搜索路径中。

//ContextMenu.h
#pragma once
template <class T>
class CContextMenu
{
public:
       BOOL CreateContextMenu(UINT ID_Menu)
       {
              T* pT = static_cast<T*>(this);
              CMenu menu;
              menu.LoadMenu(ID_Menu);
              CMenu SubMenu(menu.GetSubMenu(0));
              POINT pos;
              GetCursorPos(&pos);
              SubMenu.TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, pos.x, pos.y, pT->m_hWnd);
              return TRUE;
       }
};

//ShellIcon.h
#pragma once
#define WM_ICON WM_USER + 180
template <class T, class MenuT, int MenuID>
