写了一段用richedit调用并打开一个txt文件的代码，出现一个问题，在richedit里打开一个txt后所有文本默认选中。请问该如何取消选中？相关代码如下：
/////////////////////////////////////////////////////////////////////////////
// CLoginLog message handlers

DWORD CALLBACK MyStreamInCallback(DWORD dwCookie, LPBYTE pbBuff, LONG cb, LONG *pcb)
{
CFile* pFile = (CFile*) dwCookie;

*pcb = pFile->Read(pbBuff, cb);

return 0;

}

BOOL CLoginLog::OnInitDialog()
{
CDialog::OnInitDialog();

// TODO: Add extra initialization here

CFile cFile(theApp.sPath+"//log.txt", CFile::modeRead);
EDITSTREAM es;

es.dwCookie = (DWORD) &cFile;
es.pfnCallback = MyStreamInCallback;
m_log.StreamIn(SF_TEXT, es);
/* m_log.HideSelection(TRUE,TRUE);
// ::SendMessage(m_log.m_hWnd,EM_HIDESELECTION,1,0);
CHARRANGE cr;
cr.cpMax=cr.cpMin=0;
m_log.SetSel(cr);*/

return TRUE; // return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}
