in the 0.24 version is a serious bug when you try to extract a file stored in a blob field following code:

FS := TFileStream.Create(NewFileName,fmCreate);
BS := dm.thefile.CreateBlobStream(dm.thefile.FieldByName('datei'),bmRead);
FS.CopyFrom(BS,BS.Size);
BS.Free;
FS.Free;

the progam does nothing and fails

in the 0.22 version it works

could you fix that cause with 0.22 version i always get in network use a error when i refresh the data after some time

Hello,

We have already fixed this problem. This fix will be included in the next IBDAC build.
You can check if the connection is valid by executing a dummy query. Here is an example:

Code: Select all

function IsOnline(con: TIBCConnection): boolean;
begin
  Result := False;
  try
    con.ExecSQL('Select 1 from rdb$database', []);
    Result := True;
  except
  end;
end;

We will release the new IBDAC version as soon as RAD Studio XE2 is released. Approximately it will happen in two or three weeks.
