Shell_NotifyIcon出现的问题

[yuanye2008]

我在MainFrm.cpp 的OnCreate中，增加下列代码，目的是在状态栏加载图表。
图表加载成功，但是只要鼠标一放到图标上面，图表就消失了！
应该怎么处理，是不是设置notifydata.szTip的时候出现了错误！？
m_hIcon1 = AfxGetApp()->LoadIcon(IDI_ICON1);

NOTIFYICONDATA notifydata;
notifydata.cbSize = sizeof(NOTIFYICONDATA);
notifydata.hIcon = m_hIcon1;
notifydata.hWnd = AfxGetMainWnd()->GetSafeHwnd();
strcpy(notifydata.szTip,_T("GOOD TIPS"));
notifydata.uFlags = NIF_ICON|NIF_MESSAGE|NIF_TIP;
notifydata.uID = IDI_ICON1;

if (::Shell_NotifyIcon(NIM_ADD, ¬ifydata))
AfxMessageBox("good"); //加载成功

还要设置回调函数等东西，再仔细看看帮助。

[yuanye2008]

#define WM_NOTIFY_MESSAGE WM_USER+1

m_hIcon1 = AfxGetApp()->LoadIcon(IDI_ICON1);

NOTIFYICONDATA notifydata;
notifydata.cbSize = sizeof(NOTIFYICONDATA);
notifydata.hIcon = m_hIcon1;
notifydata.uCallbackMessage = WM_NOTIFY_MESSAGE
notifydata.hWnd = AfxGetMainWnd()->GetSafeHwnd();
strcpy(notifydata.szTip,_T("GOOD TIPS"));
notifydata.uFlags = NIF_ICON|NIF_MESSAGE|NIF_TIP;
notifydata.uID = IDI_ICON1;

if (::Shell_NotifyIcon(NIM_ADD, ¬ifydata))
AfxMessageBox("good");

增加了回调函数，问题依然存在！

如果用了MFC，用ON_MESSAGE添加消息处理函数，定义一个自定义消息由图标发出。在你的消息处理函数中处理。

谢谢，让我试试看！

我增加了添加消息处理函数

ON_MESSAGE(WM_NOTIFY_MESSAGE,OnNotifyMessage)
afx_msg LRESULT OnNotifyMessage(WPARAM,LPARAM);

LRESULT CMainFrame::OnNotifyMessage(WPARAM,LPARAM)
{
AfxMessageBox("nihao");
return 1;
}
//重写WindowProc
LRESULT CMainFrame::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
if (message == WM_NOTIFY_MESSAGE)
AfxMessageBox("good");

return CFrameWnd::WindowProc(message, wParam, lParam);
}
但还是不好用！

我贴个类给你吧，你要不想用类，自己再改改。

return SetIcon(lpResName ? AfxGetApp()->LoadIcon(lpResName) : NULL, lpTip);
};

NOTIFYICONDATA m_nid;
};

}

CTrayIcon::~CTrayIcon()
{
SetIcon(0);
}

BOOL CTrayIcon::SetIcon(UINT uID)
{
HICON hicon = NULL;
if(uID)
{
hicon = AfxGetApp()->LoadIcon(uID);
}
return SetIcon(hicon, NULL);
}

BOOL CTrayIcon::SetIcon(HICON hicon, LPCTSTR lpTip)
{
UINT msg;
m_nid.uFlags = 0;
if(hicon)
{
msg = m_nid.hIcon ? NIM_MODIFY : NIM_ADD;
m_nid.hIcon = hicon;
m_nid.uFlags |= NIF_ICON;
}
else
{
if (m_nid.hIcon == NULL)
return TRUE;

msg = NIM_DELETE;
}

if(lpTip)
_tcscpy(m_nid.szTip, lpTip);

if (m_nid.szTip[0])
m_nid.uFlags |= NIF_TIP;

if (m_nid.uCallbackMessage && m_nid.hWnd)
m_nid.uFlags |= NIF_MESSAGE;

BOOL bRet = Shell_NotifyIcon(msg, &m_nid);

if (msg == NIM_DELETE || !bRet)
m_nid.hIcon = NULL;

return bRet;
}

m_nid.hWnd = pNotifyWnd->GetSafeHwnd();

努力一下！
是不是只要双击或者单击图标，就会发送WM_ICON_MESSAGE
Process system tray icon message

谢谢楼上的各位！

我不明白自定义的消息WM_ICON_MESSAGE在什么时候被发送。
即触发什么事件会发送消息WM_ICON_MESSAGE
因为我在程序中没有发现有显式发送消息的代码，如
send(NULL,WM_ICON_MESSAGE,,)
