var
  Form1: TForm1;

  Socket: TCustomWinSocket);

Button1.Caption:='Disconnect';
end;

procedure TForm1.ClientSocket1Disconnect(Sender: TObject;
  Socket: TCustomWinSocket);
begin
StatusBar1.SimpleText:='[+] Status : Offline';
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
Memo1.Clear;
end;

procedure TForm1.Button1Click(Sender: TObject);

else
begin
ClientSocket1.Host:=Edit1.Text;
ClientSocket1.Port:=StrToInt(Edit2.Text);
ClientSocket1.Active:=True;
end;
end;

procedure TForm1.ClientSocket1Error(Sender: TObject;
  Socket: TCustomWinSocket; ErrorEvent: TErrorEvent;
  var ErrorCode: Integer);

ErrorCode:=0;
StatusBar1.SimpleText:='[+] Error connecting';
end;


procedure TForm1.FormKeyDown(Sender: TObject; var Key: Word;
  Shift: TShiftState);
begin
Memo1.Lines.Add('>'+Edit3.Text);
Memo1.Lines.Add('');
ClientSocket1.Socket.SendText(Edit3.Text);
end;

procedure TForm1.Button3Click(Sender: TObject);
begin
Memo1.Lines.Add('>'+Edit3.Text);
Memo1.Lines.Add('');
ClientSocket1.Socket.SendText(Edit3.Text);
end;

procedure TForm1.ClientSocket1Read(Sender: TObject;
  Socket: TCustomWinSocket);
var rta:string;
begin
rta:=Socket.ReceiveText;
Memo1.Lines.Add(rta);
end;

end.

Alguien me podria ayudar o explicar como soluciono esto.
