hi,
When i start an applet, and then close it, the command prompt doesn't come to editing mode. Rather I have to press Ctrl+C to exit the executing mode.
Is there a syntax which we can insert into the class , so it exits automatically..
regards

Please explain what you mean by an applet? Applets are normally part of an HTML page and execute in a browser. There is no way to "close" an applet. It's part of what a browser displays on a page.Quote:

What are you executing, where is it being executed and on what OS?
What is command prompt editing mode?
oh im sorryQuote:

when i run a swing (example, JFrame), and when i exit, the command prompt cursor doesn't come back to editing mode. it stays at executing mode.

What OS are you using?
What is "executing mode" and "editing mode"?
OS is windows XP..Quote:

How does the java program exit? Does it execute System.exit()?
Holding the ALT key with PrintScreen will get only the active window. Your images include too much junk.
well, I didn't use the command "System.exit" yet.. and atm,Quote:

I don't know what the code is doing.
Can you make a small simple program that compiles, executes and shows the problem?
Hiding the frame does NOT stop the program.Quote:

these are the codes..Quote:

});
}

I don't see anything in the program that would make it exit to the OS. Closing the JFrame does not stop the program.
Look at the API doc for the JFrame class for a method that will cause the program to exit when it is closed.
that's what i need..Quote:

thx

Here is a link to the Api docs:
Java Platform SE 6
This is something you need to have. I look at it many times a day.
Find the class in the lower left and click the link for the doc to come into the main frame.
thx a lot, and ..Quote:

Read the API doc for the System class to see how to code it.
ok and thx again for the linkQuote:
