Remote Shutdown in Delphi

Remote Shutdown
Aplikasi ini terbagi menjadi 2, yaitu aplikasi client dan aplikasi server. Aplikasi Client adalah aplikasi pengendali atau pengontrol, sedangkan aplikasi server adalah aplikasi yang di jalankan pada komputer yang ingin di kendalikan (komputer yang ingin di shutdown)
Source Code Program Client :
Berikut ini adalah source code lengkap untuk program client, ScreenShoot program jadinya bisa dilihat pada gambar berikut:

unit RSClient;

end;

var
Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button3Click(Sender: TObject);
begin
application.Terminate;  // keluar program
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
clientsocket1.Host:=edit1.Text;  // alamat ip server
clientsocket1.Active:=true;      // mengaktifkan / membuka socket sisi client
clientsocket1.Port:=1880;        // menggunakan port 1880
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
button2.Enabled:=false;    // saat aplikasi mulai dijalankan button shutdown di disable
end;

procedure TForm1.ClientSocket1Error(Sender: TObject;
Socket: TCustomWinSocket; ErrorEvent: TErrorEvent;
var ErrorCode: Integer);     //saat soket client error
begin
button2.Enabled:=false;   //disable button shutdown
showmessage(‘Error On Socket’);  //menampilkan pesan error
end;

procedure TForm1.ClientSocket1Connect(Sender: TObject;
Socket: TCustomWinSocket);   //saat sudah terhubung ke server
begin
statictext2.Caption:=’Connected to Server’;   //keterangan bahwa sudah terhubung ke server
button2.Enabled:=true;   // button shutdown di aktifkan
end;

procedure TForm1.Button2Click(Sender: TObject);
begin       //button shutdown
if (clientsocket1.Socket.Connected) then  //saat soket terhubung maka
clientsocket1.Socket.SendText(‘shutdown’); // button 2 mengirim string ke server
end;

end.
