void CGetWndDlg::OnMouseMove(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
CWnd *pWnd=WindowFromPoint(point);
if(AfxIsValidAddress(pWnd,sizeof(CWnd)))
{
  if(::IsChild(m_hWnd,pWnd->m_hWnd))
  {
   CString str;
   pWnd->GetWindowText(str);
   SetWindowText(str);
  }
}

CDialog::OnMouseMove(nFlags, point);
}

BOOL CGetWndDlg::PreTranslateMessage(MSG* pMsg)
{
// TODO: Add your specialized code here and/or call the base class
if(pMsg->message==WM_MOUSEMOVE)
{
  CPoint point(LOWORD(pMsg->lParam),HIWORD(pMsg->lParam));
  ::ClientToScreen(pMsg->hwnd,&point);
  OnMouseMove(0,point);
}

return CDialog::PreTranslateMessage(pMsg);
}
