التاكد من ان مستعمل الكمبيوتر موجود

بما أن البرنامج يشتغل يعني أن المستعمل هو من شغله :blink: ، اي انه موجود.

ممكن تجعل برنامجك ينتظر لوقت محدد، فإن لم يحصل على أي إجابة يغلق نفسه

/**
 * In java there is nothing such as keylogger where you can detect all the mouse and keyboard events on the system
 * But what you can do is to detect any mouse or keyboard events on the JVM (Java virtual machine), so if no events were
 * detected for some period, you can close the program.
 * If you want help with coding that, let me know
 * Sorry for the english post :)

شكرا ايها الاخوة على مشاركتكم

يبدو اني اخطات في توضيح ما اريده لكن

هذا ما احتاجه بالضبط ارجو ان تساعدوني بالكود لاني محتاجه وشكرا

الموضوع يحتاج إلى thread يقوم بمراقبة لوحة المفاتيح والفأرة

تحياتي

الاخ علاء الصالحي وباقي الاخوة

وجدت هذا الكود يقوم بمراقبة لوحة المفاتيح

import java.awt.*; 
import java.awt.event.*;

public class KeyListenerTester extends Frame implements KeyListener{  
  TextField t1;
  Label l1;
    public KeyListenerTester(String s )   {  
    super(s); 
  Panel p =new Panel();
  l1 = new Label ("Key Listener!" ) ;
  p.add(l1);  
  add(p);
    addKeyListener ( this ) ; 
  setSize ( 200,100 );
  setVisible(true);
  addWindowListener(new WindowAdapter(){
   public void windowClosing(WindowEvent e){
  System.exit(0);
     }
  });
  }  
    public void keyTyped ( KeyEvent e ){  
    l1.setText("Key Typed");
     }  
    public void keyPressed ( KeyEvent e){  
    l1.setText ( "Key Pressed" ) ; 
    }  
    public void keyReleased ( KeyEvent e ){  
    l1.setText( "Key Released" ) ; 
    }  
    public static void main (String[]args ){  
    new KeyListenerTester ( "Key Listener Tester" ) ; 
     }  
  }

لكن كيف احدد وقتا معينا ليطفئ لوحده؟

الفكرة في الموضوع أنك ستقوم إيقاف وتشغيل مؤقت timer

وهو الذي سيكون مسؤولاً عن عملية المتابعة لهذه الأحداث

على كل قمت بكتابة هذه الشيفرة لك

import java.awt.*;
import java.awt.event.*;

import javax.swing.Timer;

public class SessionInJFrame extends Frame implements KeyListener, ActionListener {
	Timer timer = new Timer(10000,this);
	TextField t1;
	Label l1;

	public SessionInJFrame(String s) {
		super(s);
		Panel p = new Panel();
		l1 = new Label("Key Listener!");
		p.add(l1);
		add(p);
		addKeyListener(this);
		setSize(200, 100);
		setVisible(true);
		addWindowListener(new WindowAdapter() {
			public void windowClosing(WindowEvent e) {
				System.exit(0);
			}
		});
		timer.start();
	}

	public void keyTyped(KeyEvent e) {
		l1.setText("Key Typed");
		timer.restart();
	}

	public void keyPressed(KeyEvent e) {
		l1.setText("Key Pressed");
		timer.restart();
	}

	public void keyReleased(KeyEvent e) {
		l1.setText("Key Released");
		timer.restart();
	}

	public static void main(String[] args) {
		new SessionInJFrame("Key Listener Tester");
	}

	public void actionPerformed(ActionEvent e) {
		System.exit(0);		
	}
}
