Hello,
I've developped an client/server application where the serverapp connects to a MS-SQL database. The connection is made by the TSocketConnection (Midas Tab) and using the ScktSrvr.exe.
I want to intercept the error messages like 'error reading from socket'. I understand in the TClientSocket (Internet Tab) you can write your own onerror event and catch the exceptions. So what's the real difference between those two components? Can I use the Client- and ServerSockets to connect to my database? If not how can I catch my errormessages?

Thanks,
Pascal

You will need to create a new class based on TSocketConnection

  TMySocketConnection = class(TSocketConnection)
  protected
    procedure DoError(E: Exception); override;
  end;

then override the DoError

procedure TMySocketConnection.DoError(E: Exception);
begin
  //handle error here.
  // you could call the inherited method when you
  // finish you code which just calls raise E;
end;
