class vcttip_finder

void CMsgTipMng::AddTipWindow(const CString& strTipInfo)

void CMsgTipMng::RemoveTipWindow(int nTipID)

if (vIter == m_vTipVct.end())

return;
}

m_vTipVct.erase(vIter);

m_bInShow = false;

ShowTipWindow();
}

void CMsgTipMng::ShowTipWindow()
{
if (m_vTipVct.empty())
{
return;
}

if (m_bInShow)
{
return;
}

m_bInShow = true;
m_vTipVct[0]->ShowMsgWindow();
}

3、消息框显示
m_pTipMng为成员变量，类型CMsgTipMng*。
显示对话框：

m_pTipMng->AddTipWindow(_T("Hello World!"));
