[완료]MFC에서 날짜(년,월,일)이 정상인지 확인해주는 함수가 있을까요?

  int year, month, day;
	CString strYear, strMonth, strDay;
 
	m_year.GetWindowText(strYear);
	m_month.GetWindowText(strMonth);
	m_day.GetWindowText(strDay);
 
	year = _ttoi(strYear);
	month = _ttoi(strMonth);
	day = _ttoi(strDay);
 
	COleDateTime checkDate(year, month, day, 0, 0, 0);
 
	if(checkDate.GetStatus() == 0) {
		AfxMessageBox("Valid Date");
	} else {
		AfxMessageBox("Not Valid Date!");
	}
