注：TrayIcon.h文件在附件中
1.引入TrayIcon.h(封装了Tray的一些api)//这一步并不是必需，能够直接针对api编写代码
2.在主框架文件中建立CTrayIcon对象
3.为托盘添加菜单
eg.
4.处理托盘通知消息，通常在OnCreate函数中
eg.
m_trayIcon.SetNotificationWnd(this, WM_MY_TRAY_NOTIFICATION);
m_trayIcon.SetIcon(IDR_MAINFRAME);
5.添加消息映射函数
#define WM_MY_TRAY_NOTIFICATION WM_USER+0
ON_MESSAGE(WM_MY_TRAY_NOTIFICATION, OnTrayNotification)
6.编写OnTrayNotification函数
LRESULT CTrayTestDlg::OnTrayNotification(WPARAM uID, LPARAM lEvent)
{
//add code
return m_trayIcon.OnTrayNotification(uID, lEvent);
}
7.添加气泡
若是使用的SDK为6.0 sp6 这须要修改include下的ShellApi.h文件，替换NOTIFYICONDATA定义部分

并在MFC工程的AfxStd.h文件加入

#define _WIN32_IE 0x0500 //为 IE 5.0 及更新版本改变为适当的值。
#endif
注：不修改会出现NIF_INFO未定义的编译错误
7.在TRAYICON中添加显示气泡函数，并写相应的函数体
// Show balloon tip
BOOL ShowBalloonTip(LPCTSTR szMsg, LPCTSTR szTitle,
UINT uTimeout, DWORD dwInfoFlags=NIIF_INFO);
// Show balloon tip: use resource ID instead of LPCSTR.
BOOL ShowBalloonTip(UINT uID, LPCTSTR szTitle,
UINT uTimeout, DWORD dwInfoFlags=NIIF_INFO);
函数体：
////////////////// // Show balloon tip: args give message, tiemout, etc. // BOOL CTrayIcon::ShowBalloonTip(LPCTSTR szMsg, LPCTSTR szTitle, UINT uTimeout, DWORD dwInfoFlags) { m_nid.cbSize=sizeof(NOTIFYICONDATA); m_nid.uFlags = NIF_INFO; m_nid.uTimeout = uTimeout; m_nid.dwInfoFlags = dwInfoFlags; strcpy(m_nid.szInfo,szMsg ? szMsg : _T("")); strcpy(m_nid.szInfoTitle,szTitle ? szTitle : _T("")); return Shell_NotifyIcon(NIM_MODIFY, &m_nid); } BOOL CTrayIcon::ShowBalloonTip(UINT uID, LPCTSTR szTitle, UINT uTimeout, DWORD dwInfoFlags) { CString s; return s.LoadString(uID) ? ShowBalloonTip(s, szTitle, uTimeout, dwInfoFlags) : FALSE; }
使用的时候直接调用该函数便可 注：当explorer异常重启时，程序没法找回托盘图标，找回方法会在后续添加
