MFC程序添加系统托盘

注：TrayIcon.h文件在附件中
1.引入TrayIcon.h(封装了Tray的一些api)//这一步并非必需，可以直接针对api编写代码
2.在主框架文件中创建CTrayIcon对象
3.为托盘添加菜单
eg.
m_trayIcon(菜单ID)
4.处理托盘通知消息，一般在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
如果使用的SDK为6.0 sp6 这需要修改include下的ShellApi.h文件，替换NOTIFYICONDATA定义部分

////
//// End Tray Notification Icons
////
并在MFC工程的AfxStd.h文件加入
#ifndef _WIN32_IE // 允许使用 IE 4.0 或更高版本的特定功能。
#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即可

注：当explorer异常重启时，程序无法找回托盘图标，找回方法会在后续添加
