Why my program can't exit ?thanks

here is my code:
I want to exit it when I press "F1",but it don't have any response ,why?thanks!
import java.awt.*;
class myframe
     public boolean handleEvent(Event evt)
          if (evt.id==Event.F1) System.exit(0);
          return true;
     public static void main(String args[])
          Frame f=new Frame();
          Panel p[]=new Panel[5];
          int i;
          for (i=0;i<5;i++)
               p=new Panel();
               p[i].setVisible(true);
               p[i].setSize(80,80);
               p[i].setBackground(Color.yellow);
          f.setSize(400,400);
          f.add(p[0]);
          f.setLayout(null);
          f.setVisible(true);

In other words add this code to your application:
addKeyListener(new KeyAdapter(){
     public void keyPressed(KeyEvent e){
          if(e.getKeyCode() == KeyEvent.VK_F1)
               System.exit(0);
});You need to register a key listener with your frame in order to respond to events generated by pressing of a key. And than you have to check which key was pressed.

Why this program can not update the datatbase?

The database I used is MS SQL Server 2000.
The program can run normally,but the table is not updated.
import java.sql.*;
public class BatchUpdate {
public static void main(String args[]) {
String url = "jdbc:mySubprotocol:myDataSource";
Connection con;
Statement stmt;
try {
Class.forName("myDriver.ClassName");
} catch(java.lang.ClassNotFoundException e) {
System.err.print("ClassNotFoundException: ");
System.err.println(e.getMessage());
try {
con = DriverManager.getConnection(url, "myLogin", "myPassword");
stmt = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,
ResultSet.CONCUR_UPDATABLE);
con.setAutoCommit(false);
stmt.addBatch("INSERT INTO COFFEES " + "VALUES('Amaretto', 49, 9.99, 0, 0)");
stmt.addBatch("INSERT INTO COFFEES " + "VALUES('Hazelnut', 49, 9.99, 0, 0)");
stmt.addBatch("INSERT INTO COFFEES " + "VALUES('Amaretto_decaf', 49, 10.99, 0, 0)");
stmt.addBatch("INSERT INTO COFFEES " + "VALUES('Hazelnut_decaf', 49, 10.99, 0, 0)");

System.out.print(name + " " + id + " " + price);
System.out.println(" " + sales + " " + total);
uprs.close();

con.setAutoCommit(false);The changes are not comitted to the DB when you set autocommit to false.
commit with
con.commit();
or dont set autocommit to false

Why my program can only run once?

I have a program that is already run for a long period. The program will move a axis backward to find index to
set the zero position. But in these day, i don't know why it cannot find the index and the motor will be out of
control. After i used a new motor control card to replace the old one, i can run the peogram once. But when
i use the program again, it will have the same problem. I need to shutdown the computer first to run it again.

Hi,
There are a few things that could be causing the problem. To help narrow the problem down try running
the program and then go into MAX under 1D interactive (Device and
Interfaces>>NI Motion Devices>>PCI
XXXX>>Interactive>>1D Interactive) to see if you are getting an
error there. Run the code in highlight execution, and then watch
MAX to see where the error occurs. Let
us know what axis status lights go on/off and when it happens.
Also if you could send a reduced sample of your code (one
main VI that contains just enough sub vi’s to move the motor and then read it’s
position) that still reproduces the same error then it would be easier to test
here. Let me know what you find out when
you run the code in highlight execution.
Have a great day,
GG

Can someone else try to compile this and see why the program is returning..

Can someone else try to compile this and see why the program is returning "false" when I try to delete the files on exit (at bottom of code)... I have the source code uploaded to the web as well as my 2 text test files inside a zip file(they need to be unzipped so you can try to test the program) and .class file... the program works the way i want it to, but i just can't seem to delete the 3 temporary files i use... why??? why does it return false???

I tired your program, it still gives false for files deleted. I tool the same functions you used in your program and ran it. The files get deleted. Tried this :

     public static void main(String args[]) {
          FileTest f = new FileTest();
          try {
               f.createFile();
               f.deleteFile();
          } catch(IOException ioe){
               System.out.println(ioe.getMessage());
     public void createFile() throws IOException {
          System.out.println("In create file method...");
          File test = new File("test1.txt");
          File tst = new File("text2.txt");
          PrintStream testStream = new PrintStream (new FileOutputStream (test));
          PrintStream tstStream = new PrintStream (new FileOutputStream (tst));
          testStream.println("this is a test to delete a file");
          tstStream.println("this is the second file created");
          testStream.close();
          tstStream.close();
     public void deleteFile() throws IOException {
          File test = new File("test1.txt");
          File tst = new File("text2.txt");
          System.out.println(test.delete());
          System.out.println(tst.delete());
</pre>
Also check the starting and closing braces for your if..else blocks.

Why can't the finder in Mountain Lion 10.8.2 find files that have successfully downloaded, or that other programs can find?

Why can't the finder in Mountain Lion 10.8.2 find files that have successfully downloaded, or that other programs can find?
This happens with maybe 1 out of 5 files. These are files that have either an ."aa" extention, or or are libraries that icloud can see, but finder can't.

Files beginning with a period are invisible and library files are system files. Spotlight cannot find either unless configured to do so (btw, this is not a Finder issue but a Spotlight issue.)
Get Spotlight to search system files (and more)
Enter the search term in the Finder window's search field.
Click the [+] button in the search bar to add a search option.
In the first drop down menu choose Other.
Choose “System Files” from the list that pops up (and check the box to place in drop down menu to avoid this step later,) click on the OK button.
Now back in the Finder choose Include from the second drop down menu.

Why SAP Standard Program Can full screen in different screen resolution ,but my own program can't?

How to make my program can display full screen in the different screen resolution ? can you tell me ,
Thanks everyone! eg. T-code: SOST

It appears that the full-screen display will only work on the display that has the menu bar.
You can switch the menu bar to your external display by going to Solid Apple -> System Preferences -> Displays, then Arrangement.
Grab the menu bar and drop it on the icon representing your external display.
When you full screen an app it should then full screen on the Cinema display.
I wish it would just full screen on the display the window is on, but that is evidently not the way it was designed to work.

Hi Mountain Matt,
Please make sure that you're logged in as an administrator, and that any antivirus software on your system is disabled. Then, trying downloading Acrobat from Download Acrobat products | Standard, Pro | XI, X, and run the installer.
Please let us know how it goes. If you're still having trouble and need additional help, it will be very helpful to know what version of Windows you're using.

I want to download pages, it won't let me. Says it need os x 10.9 or later-I have os x 10.8.5-all updates have been done. Why is this? what can i do? Is there another pages app i can use? thanks

Pages 5 requires OSX 10.9, for some reason that only Apple knows. Many users will not be able to install Mavericks on their Macs or do not want to.
It has simultaneously removed iWork '09/Pages '09 from the App Store.
You could ask Apple why it does things like this, but it doesn't say.
If you don't already have iWork '09 I believe you can still purchase it from Amazon.

Why Can't I Thank The Guy Who Helped Me Solve My Problem

A week or so ago, I posted a problem related to FFox not starting with my last session, when it's what I have saved in my preferences - - Well Thanks to cor-el (who is listed with an incredible 73,525 posts!) I checked http://kb.mozillazine.org/Preferences_not_saved & found I had 2! prefs.js files - naturally (thanks to MacroSloth) in 2 different locations, so as soon as I deleted the older 1 & restarted FFox, it immediately came back with my latest session, just the way I wanted
I suggest if anybody has a similar problem with FFox not starting with their latest session (when it's what you have set), then you might find the perfect solution is to check whether you have 2 prefs.js files & to delete the older
Anyway, I wanted to post my gratitude To Cor-El for the lead which led to the solution, but the mozilla support site kept telling me, after I jumped thru the hoops they set up, how I couldn't post the reply (namely these thanks to cor-el) I wanted, so I've had to resort to this work around, by posting this question : why couldn't I post my thanks on the thread itself?

Hi frebe.
support.mozilla.org is being redesigned to fix these issues. You can always create a free account here to have unlimited access to the public forums. It's very easy, and you don't have to post as a guest anymore. It also makes it easy for you to answer other users' questions, if you want to help support.mozilla.org (SUMO, for short).
Here's a link about the redesign:

My program delay on exit! Why?

I don't know why some program such as Gimp, Deadbeef or Sublime-Text take about 1.5 or 2 seconds to close. I have tried to run it in terminal, there is not other error ouput except missing GTK theme "adwaita". My Arch is up to date and it work perfect except this problem! Could any one please tell me how to solve this problem?

That could be absolutely normal. It's common for programs that they need to do some work before they close (e.g. some cleanup of temporary files, persisting the current session or configuration etc.). For me Gimp takes a second or two to close on every platform I've run it on so far. Sublime closes instantly for me most of the times, though. But I know that it persists it's current state on close, that could be the reason. Firefox also is known to take some time to completely shutdown (I think it hides the Window pretty fast, but it sometimes runs a few seconds in the background before it is finished).

Regarding how to find out a program is User Exit/executable

Hi,
Can anybody tell me how can we find wether a particular program is used in executable program (or) user exit program?
One thing we can find out is wether the program type is 'I' or 'R' etc..
Thanks in advance.

Why do we need user exit number

Hi,
why do we need user exit number?/
what is the purpose of this user exit number??
example (U22....)
thanks
Rama

Hi Rama,
Under a user exit number you can have multiple Exits/FMs. If you add this single number in CMOD for any project then you can make use of all the exits under this User Exit number.
Hope i have answered your question.
THnaks,
Anil.
