           Summary: MS Dao 3.5 with builtin OLEAUT32.DLL fail to evalutate
                    expressions in SQL sentences
           Product: Wine
           Version: 0.9.16.
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: wine-ole
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: paolo.salvan at xvision.it


Using DAO 3.5 (the engine for MS Access 97 databases) and Wine 0.9.9/15/16
I've got a trouble:

when I launch a query that uses some expressions (ie: "SELECT
Format(...) FROM Customers") the query fails, lamenting that the
function doesn't exist...
(A note that can help: Dao uses VBAR332.DLL or Expsrv.dll module to
evaluate expressions)

The console log says:
----
fixme:ole:MSFT_ReadValue BSTR length = -1?
fixme:ole:MSFT_ReadValue BSTR length = -1?
----
Replacing the builtin OLEAUT32.DLL with the native DLL everything works
ok.

The attached minimal project reproduce the problem; before starting it, install
standard Dao 3.5 setup from MS or install
http://download.danea.it/demo/def2006demo09b.exe (that is my SW, it install a
minimal Dao3.5)

BTW, this is the minimal bit of Delphi code to reproduce the problem:

procedure TForm1.Button1Click(Sender: TObject);
var
    daodbeng: DAODBEngine;
    daodb: DAODatabase;
    daors: DAORecordset;
begin
    try
        daodbeng:= OpDAO35.CreateEngine;
        daodb:= daodbeng.OpenDatabase(ChangeFileExt(Application.ExeName,
'.mdb'), false, false, '');
        // This works under Windows, fails under Wine:
        daors:= daodb.OpenRecordset('SELECT Format(#1/1/2000#, "yyyy", 2) FROM
TConfig', dbOpenDynaset, _, _);
        // This always works:
        //daors:= daodb.OpenRecordset('SELECT * FROM TConfig', dbOpenDynaset, _, _);
        daors.Free;
        daodb.Free;
        daodbeng.Free;

        ShowMessage('OK');
    except
        on e: Exception do
            ShowMessage('Exception: ' + e.ClassName + '; Msg: ' + e.Message);
    end;
end;
