Indy 10 / streams via tcp ip senden

[bernhard_LA]

Nachtrag : mit folgendem Code bekomme ich eine AV (siehe screen dump) warum kann ich auf den Stream nicht zugreifen ?

Delphi-Quellcode:

///  server read stream
function ReceiveStream(AContext: TIdContext; var AStream: TStream): Boolean; overload;
var
  LSize: LongInt;
begin
  try
  LSize := AContext.Connection.IOHandler.ReadLongInt();
  AContext.Connection.IOHandler.ReadStream(AStream, LSize);
  Result := True;
  except
  Result := False;
  end;
end;





///  client send stream 
function SendStream(AClient: TIdTCPClient; AStream: TStream): Boolean;  overload;
var StreamSize   : LongInt;
begin

  Result := True;
  try
    StreamSize := (AStream.Size);

    AStream.Seek(0, soFromBeginning);

    AClient.IOHandler.LargeStream := True;
    AClient.IOHandler.SendBufferSize := 32768;
    AClient.IOHandler.Write(LongInt(StreamSize));
    AClient.IOHandler.WriteBufferOpen;
    AClient.IOHandler.Write(AStream, StreamSize);
    AClient.IOHandler.WriteBufferFlush;
  finally
    AClient.IOHandler.WriteBufferClose;
  end;
  Result := True;
end;
