下载代码：
首先需要更新一下VC6.0的SDK，方法如下： 把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：

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 0×0500 //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 MYWM_NOTIFYICON WM_USER+1
afx_msg void OnMyIconNotify(WPARAM wParam,LPARAM lParam);
ON_MESSAGE(MYWM_NOTIFYICON,OnMyIconNotify)
添加变量： NOTIFYICONDATA m_nData;
在任务栏通知区添加图标和提示的代码：
m_nData.cbSize=sizeof(NOTIFYICONDATA);
m_nData.hWnd=GetSafeHwnd();
m_nData.uFlags=NIF_MESSAGE|NIF_INFO|NIF_ICON;
m_nData.uCallbackMessage=MYWM_NOTIFYICON;
m_nData.uID=IDR_MAINFRAME;
m_nData.hIcon=AfxGetApp()->LoadIcon(IDR_MAINFRAME);
m_nData.dwInfoFlags=NIIF_INFO;
_tcscpy(m_nData.szInfoTitle,“管理员”);
_tcscpy(m_nData.szInfo,“欢迎使用”);
Shell_NotifyIcon(NIM_ADD,&m_nData);
修改气泡提示的代码：
void CTipDlg::OnButton1()
{
_tcscpy(m_nData.szInfoTitle,“提醒你”);
_tcscpy(m_nData.szInfo,“内容改变”);
m_nData.uTimeout=1000;
m_nData.uVersion=NOTIFYICON_VERSION;
Shell_NotifyIcon(NIM_MODIFY,&m_nData);
}
删除的代码：
BOOL CTipDlg::DestroyWindow()
{
Shell_NotifyIcon(NIM_DELETE,&m_nData);
return CDialog::DestroyWindow();
}
消息处理函数：
void CTipDlg::OnMyIconNotify(WPARAM wParam,LPARAM lParam)
{
UINT uMouseMsg=LOWORD(lParam);
switch(uMouseMsg)
{
case WM_LBUTTONDBLCLK:
SendMessage(WM_CLOSE,0,0);
break;
case WM_LBUTTONDOWN:
Shell_NotifyIcon(NIM_MODIFY,&m_nData);
break;
}
}
具体使用方法请参考源代码和相关资料!
顺便提供一下在VB中的使用方法：
‘添加两个菜单’注意：要运行本全程，您必须安装 Win2000/XP 或更高版本的操作系统（Shell version 5 or better）
‘在窗口中添加菜单如下：
‘ 标题 名称
‘ 测试 mnuTest
‘ …关于 mnuabout
‘ …退出 mnuexit
‘然后将以下代码复制到窗体代码区：
Option Explicit
