任务栏图标和右键菜单

任务栏图标

1）定义CallbackMessage消息WM_MYNOTIFYICON
2）定义NOTIFYICONDATA m_nid并初始化, 其中m_nid.uCallbackMessage = WM_MYNOTIFYICON
3）添加WM_MYNOTIFYICON的消息处理函数LRESULT OnMyNotifyIcon(WPARAM, LPARAM)
4）Shell_NotifyIcon (NIM_ADD, &m_nid)添加
5）注册并处理TaskbarCreated消息来重建图标LRESULT OnTaskBarCreated(WPARAM, LPARAM)
6）Shell_NotifyIcon(NIM_DELETE, &m_nid);删除图标

右键菜单

Method - 1
1）添加菜单资源（ID，菜单项显示的文本）
2）添加菜单项处理函数，如OnContextmenuShowHide
3）加载菜单资源m_oMyMenu.LoadMenu(IDR_MYCONTEXTMENU)
4）显示菜单pMenuContext->TrackPopupMenu

Method - 2
1）定义菜单项ID
2）创建菜单oPopupMenu.CreatePopupMenu()
3）添加菜单项oPopupMenu.AppendMenu（flag, ID, 文本）
4）显示菜单oPopupMenu.TrackPopupMenu
5）销毁菜单oPopupMenu.DestroyMenu();
