很多时候我们需要在一个程序中显示不同的托盘图标，这就涉及了托盘图标的变换。

1.首先在对话框的构造函数中初始化两个图标句柄:

m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);

m_myicon1 = AfxGetApp()->LoadIcon(IDI_ICON1);
m_myicon2 = AfxGetApp()->LoadIcon(IDI_ICON2);

2.在初始化函数中初始化气泡信息

    data.cbSize = sizeof(NOTIFYICONDATA);
   data.hWnd=m_hWnd;
   //data.uCallbackMessage=WM_ONTRAY;
   //data.uFlags=NIF_MESSAGE|NIF_ICON;
   data.uFlags=NIF_ICON | NIF_TIP | NIF_INFO;//NIF_MESSAGE|NIF_ICON|NIF_INFO;
   data.dwInfoFlags=NIF_INFO;
   strcpy(data.szTip,"Tip");
   strcpy(data.szInfo,"Tip1");
   strcpy(data.szInfoTitle,"Tip2");
   data.uTimeout=1000;

   data.hIcon=m_myicon1;
   data.uID=IDR_MAINFRAME;
   Shell_NotifyIcon(NIM_ADD,&data);
   m_bChg=TRUE;
   SetTimer(1,1,NULL);

3.在定时器中变换图标和气泡：

     KillTimer(1);
   //NOTIFYICONDATA data;
   if(m_bChg)
   {
       data.hWnd=m_hWnd;
       //data.uCallbackMessage=WM_ONTRAY;
       data.uFlags=NIF_ICON | NIF_TIP | NIF_INFO;//NIF_MESSAGE|NIF_ICON|NIF_INFO;
       data.dwInfoFlags=NIF_INFO;
       strcpy(data.szTip,"gcy");
       strcpy(data.szInfo,"gcy11");
       strcpy(data.szInfoTitle,"gcy2");
       data.uTimeout=1000;
       data.hIcon=m_myicon2;
       data.uID=IDR_MAINFRAME;
       Shell_NotifyIcon(NIM_MODIFY,&data);
       m_bChg=FALSE;
   }
   else
   {
       data.hWnd=m_hWnd;
       //data.uCallbackMessage=WM_ONTRAY;
       //data.uFlags=NIF_MESSAGE|NIF_ICON;
       data.uFlags=NIF_ICON | NIF_TIP | NIF_INFO;//NIF_MESSAGE|NIF_ICON|NIF_INFO;
       data.dwInfoFlags=NIF_INFO;
       strcpy(data.szTip,"Tip3");
       strcpy(data.szInfo,"Tip31");
       strcpy(data.szInfoTitle,"Tip32");
       data.uTimeout=1000;

       data.hIcon=m_myicon1;
       data.uID=IDR_MAINFRAME;
       Shell_NotifyIcon(NIM_MODIFY,&data);
       m_bChg=TRUE;
   }
   SetTimer(1,5000,NULL);
