用ADO操作数据库时，抛出对象名XX无效，还请大虾们帮忙解决！

HRESULT hr = m_pConn.CreateInstance(__uuidof(Connection));
CString strConn = "Provider = SQLOLEDB;Server = 127.0.0.1;Database = TestADO; uid = sa;pwd = sac;";
m_pConn->Open(_bstr_t(strConn),"sa","sac",adModeUnknown);




{
if (m_pConn== NULL)
{
InitADOConnDB();

}

HRESULT hr = m_pRcst.CreateInstance(__uuidof(Recordset));
if (FAILED(hr))
{
MessageBox(NULL,"打开错误","RecordSet提示1",MB_OK|MB_ICONWARNING);
return false;
}

m_pConn->CursorLocation = adUseClient; //设置游标类型

m_pRcst->Open(bstrSql,m_pConn.GetInterfacePtr(),adOpenDynamic,adLockOptimistic,adCmdText);
  }
catch (_com_error &e)
{
MessageBox(NULL,e.Description(),"RecordSet提示2",MB_OK|MB_ICONWARNING);
return false;
}

哪出错了，求帮助

那个对象无效，就没有具体的对象吗？

跟一下哪句出错的，对象名是数据库，字段还是表这要你自己查了
