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：

////

//// Tray notification definitions

typedef struct _NOTIFYICONDATAA {

DWORD cbSize;

HWND hWnd;

SHSTDAPI_(BOOL) Shell_NotifyIconA(DWORD dwMessage, PNOTIFYICONDATAA lpData);

#ifdef UNICODE

#define Shell_NotifyIcon Shell_NotifyIconW

#else

#define Shell_NotifyIcon Shell_NotifyIconA

#endif // !UNICODE

////

//// End Tray Notification Icons

////

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：

BOOL CDlg::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);

}

双击系统托盘，使程序正常化：

LRESULT CDlg::OnNotifyIcon(WPARAM wParam, LPARAM lParam)

{

POINT rpoint;

CMenu tmenu;

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;

}
