VC6.0下实现系统托盘的气泡提示窗口(Use NIIF_INFO)

效果演示如下:

首先需要更新一下VC6.0的SDK(否则会出现编译出错)，方法如下：
1.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(重要)：

2.在stdafx.h文件中添加:

#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

3.添加函数(需要先添加系统托盘图标)

//添加成员变量
NOTIFYICONDATA m_nid;

/***************************************
 * pWnd - 窗体指针
 * szMsg - 显示的内部信息
 * szTitle - 显示的标题信息
 * uTimeout - 这个时间过后,气球自动消失(好像不启作用)
 * uCallbackMessage - 消息标识
 ***************************************/
BOOL CMyCatchFun::ShowBalloonTip(
		CWnd* pWnd,
		LPCTSTR szMsg,
		LPCTSTR szTitle,
		UINT uTimeout,
		UINT uCallbackMessage
	)
{
	m_nid.cbSize = sizeof(NOTIFYICONDATA);
	m_nid.uTimeout = uTimeout;
	m_nid.uVersion = NOTIFYICON_VERSION; 
	m_nid.dwInfoFlags = NIIF_INFO;	//如果前面修改错误,这里会发生"未定义标识符"错误
	m_nid.uFlags = NIF_MESSAGE|NIF_INFO|NIF_ICON;
	m_nid.uID = IDR_MAINFRAME;
	m_nid.hWnd = pWnd->m_hWnd;
	m_nid.hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
	m_nid.uCallbackMessage = uCallbackMessage;
	
	_tcscpy(m_nid.szInfoTitle,szTitle);
	_tcscpy(m_nid.szInfo,szMsg);

	return Shell_NotifyIcon(NIM_MODIFY,&m_nid);
}

4.修改气球提示信息

void CMyDlg::OnButton1()
{
	_tcscpy(m_nid.szInfoTitle,"提醒你");
	_tcscpy(m_nid.szInfo,"内容改变");
	m_nid.uTimeout=1000;
	m_nid.uVersion=NOTIFYICON_VERSION; 
	Shell_NotifyIcon(NIM_MODIFY,&m_nid);
}
