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)：

typedef struct _NOTIFYICONDATAA {

DWORD cbSize;

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);

}
