Each item of CListCtrl in C++ displays a different message

Add CToolTipCtrl member variables m_toolTipCtrl,CListCtrl member variables m_ListUser,CImageList member variables m_imageList

Add the following code to the OnInitDialog() function

m_BoradcastEnd.EnableWindow(FALSE);
  m_imageList.Create(32, 32, ILC_COLOR8, 2, 2);
  DWORD dwStyle = m_ListUser.GetExtendedStyle();
  dwStyle |= LVS_EX_INFOTIP;
  m_ListUser.SetExtendedStyle(dwStyle);

  for (int i=0; i<5; i++)
  {
    CBitmap bit;
    bit.LoadBitmap(IDB_TEA_ONLINE+i);
    m_imageList.Add(&bit, RGB(0, 0, 0));
    bit.DeleteObject();
  }

  EnableToolTips(TRUE);
  m_toolTipCtrl.Create(this);
  m_toolTipCtrl.SetMaxTipWidth(500);// If you block the format of this prompt message, you may have a problem and cannot wrap
  m_toolTipCtrl.Activate(TRUE);
  m_ListUser.SetImageList(&m_imageList, TVSIL_NORMAL);
  m_ListUser.InsertItem(0, "172.16.30.32.231", 0);
  m_ListUser.InsertItem(1, "172.16.30.218", 4);
  CRect rect;
  m_ListUser.GetItemRect(0, &rect, LVIR_BOUNDS);
  m_toolTipCtrl.AddTool(&m_ListUser, "MAC:/nHost:/nIP:", &rect, 1);
  m_ListUser.GetItemRect(1, &rect, LVIR_BOUNDS);
  m_toolTipCtrl.AddTool(&m_ListUser, "gggggggggg/nggggggggsfgsfgsfg", &rect, 2);

Add virtual function PreTranslateMessage()

Add the following code to the function

BOOL CMutiScreenDlg::PreTranslateMessage(MSG* pMsg)
{
  // TODO: Add your specialized code here and/or call the base class
  m_toolTipCtrl.RelayEvent(pMsg);

  return CDialog::PreTranslateMessage(pMsg);
}
