CEdit control의 font 바꾸기

BOOL CMyDlg::OnInitDialog() 
{
LOGFONT lf;

memset(&lf, 0, sizeof(LOGFONT));
lf.lfCharSet = 0x81;			// 한글 Character Set
lf.lfHeight = 20;			// 20 point 크기
strcpy(lf.lfFaceName, "궁서체"); 	// 궁서체로 font setting
m_font.CreateFontIndirect(&lf);	

CEdit* pCtlEdit = (CEdit*) GetDlgItem(IDC_EDIT1); // edit control의 
                                                  // pointer를 가져옴
pCtlEdit->SetFont((CFont*)&m_font, TRUE);

return TRUE;
}
