    _RecordsetPtr pRstAuthors=NULL;
     
    _ConnectionPtr  pConnection=NULL;
     
    // Call Create instance to instantiate the Record set
    hr = pRstAuthors.CreateInstance(__uuidof(Recordset));
    pConnection.CreateInstance(_uuidof(Connection));
    pConnection->ConnectionString="Provider=Microsoft.ACE.OLEDB.12.0;Data Source=E:\\Sankar\\Database1.accdb";
    pConnection->ConnectionTimeout = 30;  
    if(FAILED(hr))
    {

        return;
    }
    //Open the Record set for getting records from Customer table
    pRstAuthors->Open("SELECT* FROM Customers","Provider=Microsoft.ACE.OLEDB.12.0;Data Source=E:\\Sankar\\Database1.accdb",adOpenStatic,adLockReadOnly, adCmdText);
 
    _bstr_t valField1;
    int valField2;
    pRstAuthors->MoveFirst();
    if (!pRstAuthors->EndOfFile)
    {
        while(!pRstAuthors->EndOfFile)
        {
            valField1 = pRstAuthors->Fields->GetItem("username")->Value.intVal;
        }
    }
}
catch(_com_error & ce)
{
    //sprintf("Error:%s\n",ce.Description);
}
CoUninitialize();
