Hi,

i have in the dpr the following line:

ReportMemoryLeaksOnShutdown := True;

and here is the rest of my source:

Code: Select all

procedure TForm3.FormShow(Sender: TObject);
var
  lDataSet : TVirtualDataSet;
begin
  lDataSet := TVirtualDataSet.Create(nil);

  try
    lDataSet.OnGetRecordCount := DataSetGetRecordCount;
    lDataSet.OnGetFieldValue  := DataSetGetFieldValue;
    lDataSet.FieldDefs.Add('test', ftWideMemo);
    lDataSet.Active := True;
    lDataSet.Last;
    lDataSet.First;
  finally
    FreeAndNil(lDataSet);
  end;

end;

If I close the application I recive a memory leak:
TCompressedBlobData x 6
Unknown x 3
TCompressedBlob x3

If i do the same with a ftString-Field, I have no Problem.

Thank you.

Regards, Jan

Thank you for the information. We reproduced the problem and fixed this error. The fix will be included in VirtualDAC next build. In addition, this build will support RAD Studio Delphi 10.2 Tokyo . We are planning the release of this VirtualDAC version next week.
