Streamproblem

[Spurius]

So,
ich wollte das ganze jetzt mit Indy/ TCP versenden, aber es geht irgendwie nicht:

Delphi-Quellcode:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, IdTCPConnection, IdTCPClient, IdBaseComponent,
  IdComponent, IdTCPServer;

type
  TForm1 = class(TForm)
    Button1: TButton;
    Button2: TButton;
    Memo1: TMemo;
    Server: TIdTCPServer;
    Client: TIdTCPClient;
    Label1: TLabel;
    procedure Button1Click(Sender: TObject);
    procedure ServerExecute(AThread: TIdPeerThread);
    procedure ServerConnect(AThread: TIdPeerThread);
    procedure FormDestroy(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;
 type
  TTest = record
   a, b, c: integer;
  end;
var
  Form1: TForm1;
  Stream, stream2: TMemoryStream;
implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
var Test: TTest;
begin
 client.Connect;
 Test.a := 1;
 Test.b := 2;
 Test.c := 3;
 Stream := TMemoryStream.Create;
 Stream.Write(Test, Sizeof(Test));
 Client.WriteStream(stream, true, true, 0);
end;

procedure TForm1.ServerExecute(AThread: TIdPeerThread);
begin
 Label1.Caption := 'Connected';
end;

procedure TForm1.ServerConnect(AThread: TIdPeerThread);
var test2: TTest;
begin
 Stream2 := TMemoryStream.Create;
 athread.Connection.ReadStream(stream2);
 Stream2.Position := 0;
 Stream.Read(Test2, Sizeof(TTest));
 memo1.Lines.Add(inttostr(test2.a));    // wenn a oder b dann kommt eine große zahl, wenn c kommt 0 
end;

procedure TForm1.FormDestroy(Sender: TObject);
begin
 Stream.Free;
 stream2.Free;
end;

end.

Was mach ich da falsch?
