VC实现托盘气泡提示

如果在VC6.0环境下，要将ShellAPI.h文件中的关于任务栏提示的函数和常量替换为下面的内容：

/// /
/// /Traynotificationdefinitions
/// /

typedef struct _NOTIFYICONDATAA{
DWORDcbSize;

#ifdefUNICODE
#define Shell_NotifyIconShell_NotifyIconW
#else
#define Shell_NotifyIconShell_NotifyIconA
#endif // !UNICODE

/// /
/// /EndTrayNotificationIcons

然后在stdafx.h文件中添加以下内容：

#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

自定义消息及处理函数：

#define WM_ICONNOTIFY WM_USER + 909 //图标响应消息(lParam)
#define ID_TASKBARICON 100 //参数(wParam)
ON_MESSAGE(WM_ICONNOTIFY, OnNotifyIcon)

添加变量： NOTIFYICONDATA m_nid;

在触发事件函数中添加代码：

SetIcon();
ShowBalloonTip("正在监控中...", "进程监控程序", 3000, 1);

初始化系统托盘图标：

void CDlg::SetIcon()
{
m_nid.cbSize = sizeof (NOTIFYICONDATA);
m_nid.hWnd = m_hWnd;
m_nid.uID = ID_TASKBARICON; // 发出的消息中的wParam参数
m_nid.uFlags = NIF_ICON | NIF_MESSAGE | NIF_TIP;
m_nid.uCallbackMessage
= WM_ICONNOTIFY; // 点击托盘图标系统发出的消息（即发出的消息中的lParam参数）
m_nid.hIcon = LoadIcon(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDR_MAINFRAME)); // 图标文件
strcpy(m_nid.szTip, " 进程监控程序 " );
Shell_NotifyIcon(NIM_ADD, & m_nid); // 加入图标
ShowWindow(SW_HIDE); // 隐藏窗体
}

托盘气泡提示函数：

BOOLCDlg::ShowBalloonTip(LPCTSTRszMsg,LPCTSTRszTitle,UINTuTimeout,DWORDdwInfoFlags)
{
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);
}

双击系统托盘，使程序正常化：

LRESULTCDlg::OnNotifyIcon(WPARAMwParam,LPARAMlParam)
{
POINTrpoint;
CMenutmenu;
GetCursorPos( & rpoint);
// 如果在托盘图标上双击左键
if ((wParam == ID_TASKBARICON) && (lParam == WM_LBUTTONDBLCLK))
{
ShowWindow(SW_SHOW); // 显示窗体
Shell_NotifyIcon(NIM_DELETE, & m_nid); // 删除系统托盘图标
}
// 如果在托盘图标上单击右键
if ((wParam == ID_TASKBARICON) && (lParam == WM_RBUTTONDOWN))
{
tmenu.LoadMenu(IDR_MAINMENU); // 加载系统主菜单
SetForegroundWindow(); // 将程序置于桌面顶部，否则菜单将不会消失
// 在点击图标处弹出系统菜单的第一项
tmenu.GetSubMenu( 0 ) -> TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON,rpoint.x,rpoint.y, this );
}
return 0 ;
}
