Absolut keinen Plan (Indy Server/Client)

[freak4fun]

Hallo,

ich hab alles durchgelesen und jemehr ich gelesen hab, desto weniger hab ich verstanden.
Ich will ein Chat zwischen 2 Computern. Dabei müssen die ja beide Server und Client sein.
Wie geht das?

Delphi-Quellcode:

unit Unit1;

interface

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

type
  TMainform_Form = class(TForm)
    TCPClient: TIdTCPClient;
    TCPServer: TIdTCPServer;
    Chatfield_REdit: TRichEdit;
    Button1: TButton;
    Eingabe_Edit: TEdit;
    procedure Button1Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
    procedure TCPServerExecute(AThread: TIdPeerThread);
    procedure FormClose(Sender: TObject; var Action: TCloseAction);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Mainform_Form: TMainform_Form;

implementation

{$R *.dfm}

procedure TMainform_Form.Button1Click(Sender: TObject);
begin
  TCPClient.Connect;
{  TCPClient.WriteLn(Eingabe_Edit.Text);
  Eingabe_Edit.Text := '';
  TCPClient.Disconnect;
  TCPServer.Active := False;    }



end;

procedure TMainform_Form.FormCreate(Sender: TObject);
begin
  TCPServer.Active := True;

end;

procedure TMainform_Form.TCPServerExecute(AThread: TIdPeerThread);
begin
  AThread.Connection.WriteLn('Connected...');
end;

procedure TMainform_Form.FormClose(Sender: TObject;
  var Action: TCloseAction);
begin
  TCPClient.Disconnect;
  TCPServer.Active := False;
end;

end.

Das ist was ich habe.
