BOOL CLG3200DemoApp::InitInstance()
{
    AfxInitRichEdit2();
    // call  to initialize richedit2 library.

m_pEdit = (CRichEditCtrl*)GetDlgItem(IDC_RICHEDIT21);
m_pEdit->SetFont(&m_font);

SendDlgItemMessage(IDC_RICHEDIT21, WM_SETFONT, (WPARAM)font.m_hObject, FALSE);

响应 ENM_CHANGE

CRichEditCtrl *pRichEdit = (CRichEditCtrl*)GetDlgItem(IDC_RICH_APDU);
	pRichEdit->SetEventMask(EN_MSGFILTER | ENM_CHANGE);
