Finde Fehler bei meinem Chat Programm nicht

[bl4ckb1rd]

Also mein 1ter Schritt ist es die SErver-Kommunikation hinzubekommen.

Hier der aktuelle Code vom Client:

Delphi-Quellcode:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, ExtCtrls, StdCtrls, XPMan, ScktComp;


type  TChatNachricht = Record
        nick: string[255];
        chat: string[255];
        state: string[255];
        hand: string[255];
        table: string[255];

      end;


type
  TForm1 = class(TForm)
    Label1: TLabel;

    Image7: TImage;
    Button7: TButton;
    XPManifest1: TXPManifest;

    chat: TEdit;
    send: TButton;
    Label8: TLabel;
    Label9: TLabel;
    Label10: TLabel;
    Label11: TLabel;
    Label12: TLabel;

    Label14: TLabel;

var

procedure TForm1.Button7Click(Sender: TObject);
begin
close;
end;

//---------------------------------------------------------------------------------------------------------

    Memo1.lines.add (Nachricht.nick+': '+Nachricht.chat);
  end
  else
  if Nachricht.state <> 'msg' then begin
    Memo1.lines.add ('Es wurden unbekannte dateien empfangen');
  end;

end;



procedure TForm1.ClientSocket1Connect (Sender: TObject; Socket: TCustomWinSocket);

Kann es sein das die sockets aufhören zu arbeiten wenn die Oberfläche zu viele inhalte enthält??
