MFC程序添加系統托盤

注：TrayIcon.h文件在附件中
1.引入TrayIcon.h(封裝了Tray的一些api)//這一步並非必需，可以直接針對api編寫代碼
2.在主框架文件中創建CTrayIcon對象
3.爲托盤添加菜單
eg.

m_trayIcon(菜單ID)

4.處理托盤通知消息，一般在OnCreate函數中
eg.

m_trayIcon.SetNotificationWnd(this, WM_MY_TRAY_NOTIFICATION);
m_trayIcon.SetIcon(IDR_MAINFRAME);

5.添加消息映射函數

#define WM_MY_TRAY_NOTIFICATION WM_USER+0
ON_MESSAGE(WM_MY_TRAY_NOTIFICATION, OnTrayNotification)

6.編寫OnTrayNotification函數

LRESULT CTrayTestDlg::OnTrayNotification(WPARAM uID, LPARAM lEvent)
{
//add code

return m_trayIcon.OnTrayNotification(uID, lEvent);
}

7.添加氣泡
如果使用的SDK爲6.0 sp6 這需要修改include下的ShellApi.h文件，替換NOTIFYICONDATA定義部分

typedef struct _NOTIFYICONDATAA {
                DWORD cbSize;

#ifdef UNICODE
#define Shell_NotifyIcon    Shell_NotifyIconW
#else
#define Shell_NotifyIcon    Shell_NotifyIconA
#endif // !UNICODE

////
//// End Tray Notification Icons
////

並在MFC工程的AfxStd.h文件加入

#ifndef _WIN32_IE // 允許使用 IE 4.0 或更高版本的特定功能。
#define _WIN32_IE 0x0500 //爲 IE 5.0 及更新版本改變爲適當的值。
#endif

注：不修改會出現NIF_INFO未定義的編譯錯誤
7.在TRAYICON中添加顯示氣泡函數，並寫相應的函數體    

// 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);

函數體：

//////////////////
// 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;
}

使用的時候直接調用該函數即可

注：當explorer異常重啓時，程序無法找回托盤圖標，找回方法會在後續添加
