找不到_StreamPtr、Stream、adExecuteStream的定义

[modena]

#import "C:\Program Files\Common Files\System\ADO\msado15.dll" no_namespace rename("EOF", "EndOfFile")

class CMyDataClass
......
public:
_RecordsetPtr m_pMyDataSet;

protected:
_ConnectionPtr m_pConnection;
_CommandPtr m_pCommandPtr;
_StreamPtr m_pStream;

......

THROW_ERR( m_pStream.CreateInstance( __uuidof( Stream ) ) );
......
m_pStream = m_pCommandPtr->Execute( NULL, NULL, adCmdStoredProc | adExecuteStream );
......

编译时找不到_StreamPtr、Stream、adExecuteStream的定义，不使用_StreamPtr就一切正常

请各位大侠赐教

please try this:
#import "C:\Program files\Common Files\System\Ado\msado15.dll" rename_namespace("MSXML") rename("EOF", "ADOEOF")

#import "c:\winnt\system32\msxml.dll"
using namespace MSXML;
