Einfaches Command per Server/Client

[RobertS]

Code:

Delphi-Quellcode:

unit Unit1;

interface

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

type
  TForm1 = class(TForm)
    IdTCPServer1: TIdTCPServer;
    IdTCPClient1: TIdTCPClient;
    glSpeedButton1: TglSpeedButton;
    glSpeedButton2: TglSpeedButton;
    servermemo: TMemo;
    clientmemo: TMemo;
    Button1: TButton;
    Button2: TButton;
    procedure glSpeedButton1Click(Sender: TObject);
    procedure FormClose(Sender: TObject; var Action: TCloseAction);
    procedure glSpeedButton2Click(Sender: TObject);
    procedure IdTCPServer1Connect(AThread: TIdPeerThread);
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
    procedure IdTCPServer1TIdCommandHandler1Command(ASender: TIdCommand);
    procedure IdTCPServer1TIdCommandHandler0Command(ASender: TIdCommand);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.glSpeedButton1Click(Sender: TObject);
begin
IdTCPServer1.Active:=True;

Form1.Caption:='Server';
servermemo.Visible:=True;
end;

procedure TForm1.glSpeedButton2Click(Sender: TObject);
begin
glSpeedButton2.Enabled:=False;
IdTCPClient1.Connect();
Form1.Caption:='Client';
clientmemo.Visible:=True;
Button1.Visible:=True;
Button2.Visible:=True;
end;


procedure TForm1.FormClose(Sender: TObject; var Action: TCloseAction);
begin
if IdTCPServer1.Active then IdTCPServer1.Active:=False;
if IdTCPClient1.Connected then IdTCPClient1.Disconnect;

end;

procedure TForm1.IdTCPServer1Connect(AThread: TIdPeerThread);
begin
servermemo.Lines.Add('Client verbunden');

end;

procedure TForm1.Button1Click(Sender: TObject);
begin
IdTCPClient1.SendCmd('test');
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
IdTCPClient1.WriteLn('test');
end;


procedure TForm1.IdTCPServer1TIdCommandHandler0Command(
  ASender: TIdCommand);
begin
showmessage('Command2');
end;


procedure TForm1.IdTCPServer1TIdCommandHandler1Command(
  ASender: TIdCommand);
begin
showmessage('Command1');
end;

end.

Wo zur Zeit noch "showmessage('Command1')" steht soll eben dann die "Antwort" hin.

Danke für Anregungen
