Blob fields in TDbf

[cdbc]

Hi all.

I'm having a problem with a blob-field in dbf, when i try to dump some data from firebird 2.0 to dbf, all fields except blobs are written correctly to dbf-file... I can't seem to figure it out, what am I missing?!?

Code: [Select]

var
  I,J: integer;
  S: string;
  StrmD,StrmS: TStream;
begin
  Memo1.Clear;
  zConnection1.Connect;
  ZQuery1.SQL.Text:= 'select * from diary;';
  ZQuery1.Open;
  Memo1.Lines.Add('Source dataset opened...');
  Dbf1.FieldDefs.Clear;
  for I:= 0 to ZQuery1.FieldDefs.Count - 1 do begin
    Dbf1.FieldDefs.Add(ZQuery1.FieldDefs[I].Name,ZQuery1.FieldDefs[I].DataType);
    S:= S+' | '+ZQuery1.FieldDefs[I].Name;
  end;
  Memo1.Lines.Add(S);
  Memo1.Lines.Add('Creating destination dataset...');
  Dbf1.CreateTable;
  Dbf1.Open;
  ZQuery1.First;
  Memo1.Lines.Add('Dumping data to Dbf...'); //exit;
  while not ZQuery1.EOF do begin
    Dbf1.Insert;
    Dbf1.FieldByName('id_diary').AsInteger:= ZQuery1.FieldByName('id_diary').AsInteger;
    Dbf1.FieldByName('id_locatio').AsInteger:= ZQuery1.FieldByName('id_location').AsInteger;
    Dbf1.FieldByName('adate').AsInteger:= ZQuery1.FieldByName('adate').AsInteger;
    Dbf1.FieldByName('acomment').AsString:= AnsiToUtf8(ZQuery1.FieldByName('acomment').AsString);
    Dbf1.FieldByName('haspics').AsInteger:= ZQuery1.FieldByName('haspics').AsInteger;
    StrmD:= Dbf1.CreateBlobStream(Dbf1.FieldByName('atext'),bmReadWrite);
    StrmS:= ZQuery1.CreateBlobStream(ZQuery1.FieldByName('atext'),bmRead);
    try
      StrmS.Position:= 0;
      J:= StrmS.Size; Memo1.Lines.Add('Source stream size: '+inttostr(J));
      StrmD.CopyFrom(StrmS,StrmS.Size);
      StrmD.Position:= 0;
      J:= StrmD.Size; Memo1.Lines.Add('Destination stream size: '+inttostr(J));
      Dbf1.Post;
    finally
      StrmS.Free;
      StrmD.Free;
    end;
//    Dbf1.Post;
    ZQuery1.Next;
    Application.ProcessMessages;
    Sleep(10);
  end;
  Memo1.Lines.Add('Done dumping data to Dbf, cleaning up.');
  Dbf1.Close;
  ZQuery1.Close;
  ZConnection1.Disconnect; 

TIA Benny
