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:
|
1 2 3 |
#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
|
1 2 3 4 5 6 7 8 |
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); } |

因为你没有更新,造成的没有定义的标识符的错误

为何我按照上述步骤后，VC6还是会报

不好意思,很抱歉程序的源代码不能给你,这个也不是”开源”的东西,今后我还会将程序改版~
其实相关的技术都已经写在博客里了
有什么问题一起讨论的

谢谢，但我还是不明白
能把你的那个工程发到我的邮箱吗？

uCallbackMessage是回调消息的标识,用来响应事件的
一般是用户自己定义的消息
示例代码:
//用户定义的消息
#define MYWM_NOTIFYICON WM_USER+1
//响应该消息
LRESULT CMyDlg::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
// TODO: Add your specialized code here and/or call the base class
switch(message)
{
case MYWM_NOTIFYICON:
//如果是用户定义的消息
if(lParam==WM_LBUTTONDOWN)
{
//鼠标左键单击图标时
MessageBox(“鼠标左键单击”);
}
else if(lParam==WM_RBUTTONDOWN)
{
//鼠标右键单击图标时
MessageBox(“鼠标右键单击”);
}
break;
}
return CDialog::WindowProc(message, wParam, lParam);
}

我现在正在找这个方面的资料
问下BOOL CMyCatchFun::ShowBalloonTip(
CWnd* pWnd,
LPCTSTR szMsg,
LPCTSTR szTitle,
UINT uTimeout,
UINT uCallbackMessage
)
这个函数最后一个参数uCallbackMessage具体是什么意思？？
