ADODB::Streams对象操作.

谁有这方面的经验或信息...

ADO对象的流接口：
_StreamPtr pstm(_uuidof(Stream));
_variant_t var(DISP_E_PARAMNOTFOUND,VT_ERROR);
pstm->Type = adTyepeBinary;
hr = pstm->raw_Open(var,adModeUnkown,adOpenStreamUnspecified,NULL,NULL);
hr = pstm->Write(pset->GetCollect("FieldName");
pset->Close();
//再通过流接口访问二进制数据

ADODB::_StreamPtr stream;
stream.CreateInstance(__uuidof(ADODB::Stream));
stream->PutType(ADODB::adTypeBinary);
stream->Open(vtMissing,ADODB::adModeUnknown,ADODB::adOpenStreamUnspecified,"","");
stream->LoadFromFile("c:\\1.jpg");
stream->SaveToFile("c:\\2.jpg",ADODB::adSaveCreateOverWrite);
