ocx 中使用 richedit 打开大文件，报“内存不足，无法完成此操作”

[zacc]

如题，我在ocx中封装了richedit 控件，当打开一个20M大小的rtf文件时，出现上述情况。很是疑惑，求解答。谢谢

打开文件的代码：

ReadFromFile( LPCTSTR lpszFilePath )
{
	
	CLog::LogPrintfDetailEx("CNetRichEditCtrl::ReadFromFile %s",lpszFilePath);
	

	CFile crtfFile;
	if(crtfFile.Open(lpszFilePath,CFile::modeRead|CFile::shareDenyNone|CFile::typeBinary,NULL))
	{
		CLog::LogPrintfDetailEx("打开文件成功");
		EDITSTREAM edtStream;
		ZeroMemory(&edtStream,sizeof(EDITSTREAM));
		edtStream.dwCookie =(DWORD) &crtfFile;
		edtStream.pfnCallback = CNetRichEditCtrl::CBEditStreamIn;
		SendMessage(EM_STREAMIN,SF_RTF,(LPARAM)&edtStream);

		crtfFile.Close();
		CLog::LogPrintfDetailEx("streamin file ret :%u",edtStream.dwError);
		return edtStream.dwError;
	}
	CLog::LogPrintfDetailEx("打开文件失败");
	return -1;
}
CBEditStreamIn( DWORD dwCookie, LPBYTE pbBuff, LONG cb, LONG *pcb )
{
	CLog::LogPrintfDetailEx("EditStreamCallback  dwcookie:%u\n",dwCookie);
	CFile* pFile = (CFile*)dwCookie;
	*pcb = pFile->Read(pbBuff,cb);
	return 0;
}

richedit 控件，直接打开一个20M的
是否报错？
