On the cancel option you exit the application. You are not involving with any frame there.

Then How can i do that.Any idea about that..

If you want to close/dispose a frame you need a reference to that frame. Is this done on the same frame you are talking about?

Code:

---

System.ext(0)

---

then code is hange...

So how i can do that.I have no idea bout that..

Plz help me

In all three options(Yes, No, Cancel) you have done the same thing at the end. Exit the application.

Code:

---

System.exit(0);

---

You say that on yes option frame is close. Where's the code? I can't see any related code there. Only thing is you execute the browser with a specified URL.

As I said, what you have to do is, use a reference to the frame. You can use dipose() or exit() methods.

                      try

                      {
                        System.out.println("Exception caught : " + exception.getMessage());

                    }

I don't know what you are talking about. Can show me only the reference to the frame here. Highlight the reference on the above code to see me.

I'm confusing that you know about the object reference in Java.

Sir give me tips to solve it..

Simply call a function using that reference in the main frame class. On that method dispose/exit the frame.

Sir i want to know some concept.Why it is not working for Cancel option and other hand it is working good for yes option.What's a resion behiend it.Just i want to know hide concept..

Plz help me

In your code, even on the Yes option it can't work. See the code in Yes and Cancel options. There is no different. So what are you talking about, in any option you don't have handle any event on the frame.

Sir i create a even handel in frame class.Now i call it in main class..

Code:

---


protected void processWindowEvent(WindowEvent e) {

        if (e.getID() == WindowEvent.WINDOW_CLOSING) {
       
            int exit = JOptionPane.showConfirmDialog(this, "Are you sure?");
            if (exit == JOptionPane.YES_OPTION) {
                System.exit(0);
            }
           
        } else {

            // If you do not want listeners processing the WINDOW_CLOSING
            // events, you could this next call in an else block for the:
            //    if (e.getID() ...)
            // statement. That way, only the other types of Window events
            // (iconification, activation, etc.) would be sent out.

            super.processWindowEvent(e);
        }
    }

can you give me some example rellated to this sir..

Plz help me

Seems you copied this code somewhere. If not you should know what happened here. That code is related to the closing event of the frame. Not the JOptionPane stuff you are talking about earlier.
