Without fishing through the world here:
frame = new JFrame("Console Screen");
Container contentPane = frame.getContentPane();
contentPane.setLayout(new FlowLayout());Notice you set contentPane to the ContentPane of your "Console Screen" and then proceed to add everything to it.
Other than that, I'd ask you: do you know how to work your debugger?

Is there a error with this code
import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;
public class ClickMe extends Applet implements MouseListener {
private Spot spot = null;
private static final int RADIUS = 7;
public void init() {
addMouseListener(this);
public void paint(Graphics g) {
//draw a black border and a white background
g.setColor(Color.white);
g.fillRect(0, 0, getSize().width - 1, getSize().height - 1);
g.setColor(Color.black);
g.drawRect(0, 0, getSize().width - 1, getSize().height - 1);
//draw the spot
g.setColor(Color.red);
if (spot != null) {
g.fillOval(spot.x - RADIUS, spot.y - RADIUS, RADIUS * 2, RADIUS * 2);
public void mousePressed(MouseEvent event) {
if (spot == null) {
spot = new Spot(RADIUS);
spot.x = event.getX();
spot.y = event.getY();
repaint();
public void mouseClicked(MouseEvent event) {}
public void mouseReleased(MouseEvent event) {}
public void mouseEntered(MouseEvent event) {}
public void mouseExited(MouseEvent event) {}
When I compile the the code I get a "cannot resolve symbol"
private Spot spot = null;
spot = new Spot(RADIUS);
I don't know if these are errors in the code'cannot resolve symbol' errors usually mean a problem with the declarations and initialisations at the start of your class. This is specifically to do with your line private Spot spot = null;
i haven`t much time to look at your code, but i would suggest getting rid of the null initialisation here, and do you ever actually change this value? after a quick look it seems that you only query it to see if the variable spot is null. if you never affect this value, then it will always be null and only one if statement will ever be executed.
but as i said i haven`t any time, so could be off here

HT201210 why is there an error occurring when trying to do a software update ios6 on iphone 4s
why is there an error occurring when trying to do a software update ios6 on iphone 4s??

It has the error range of 3000's which states
Errors 3000-3999 (3002, 3004, 3013, 3014, 3018, 3164, 3194, and so on): Error codes in the 3000 range generally mean that iTunes cannot contact the gs.apple.com server on ports 80 or 443. This may be because out-of-date or incorrectly configured security or firewall software is interfering, an old version of iTunes is installed, an entry in your hosts file redirecting requests to gs.apple.com (see error 1004 above), or because of your Internet proxy settings. If you are using a proxy, try without using one or with a known-good network. If that does not resolve the issue, follow iTunes for Windows: Troubleshooting security software issues. Error 3014 may indicate that you need to free up more disk space on the computer before trying to restore again. Error 3194 most likely indicates you do not have the latest version of iTunes installed Update to the latest version of iTunes. -
Errors with SAP GUI 7.10 issues with IE 7.0? and most curr patches?
We are attempting to patch our SAP GUI 7.0 with the most recent GUI patches
GUI patch 12
BW patch 500
BI patch 900
we are applying these patches to correct the following
>preview and printing of blank pages with web browser(ie 6.0)
>german lang. toolbar appearing
>missing active components when using analyzer (BW 3x)
>BI rspc error 'x dump'
these issues above have been corrected, however we are now having issues with this GUI and IE 7.0 , printing errors
As anyone had these same issues above, and could you recommend on what patch combination (if any) have corrected them
We have worked on this project for the last few months, to get the correct combination of patches that would not break anything else installed. But, now we are finding that we may have issues with IE 7,0 and the SAP GUI with the above patches.
Please advise
Mariawhat happens on the desktops with IE 7.0 is that it looses printing capabilities.

When I try to play a song on I-Tunes, I receive the Message "The song can not be used because the original can not be found. Can anyone out there help me with this problem?
The iTunes application saves your iTunes Store purchases--as well as any music, audiobooks, or videos you import--to your computer's hard disk, not the iTunes application itself.
The error message you note indicates that the purchase in question can’t be located where it is stored in your iTunes Music folder in order to play it, and may have been moved or deleted.
You will need to help iTunes locate the file. Follow the steps in this article:

I have photos in a DVD. In order to visualize them in iPhoto, must I necessarily import them? Can't I see the pictures from the media without importing? If not, is there any application with this functionality? I need an app that allows me to navigate through the photos without selecting all of them. I realy dont't like pre-visualization for photos...
In order to visualize them in iPhoto, must I necessarily import them?
iPhoto is a Database. Before it can work with any data it must be imported to the database, so yes it is necessry to import them.
Can't I see the pictures from the media without importing?
See above.
If not, is there any application with this functionality?
Hundreds. Any image viewer will do the job. On your Mac the Finder has QuickLook and there is the Preview app as well. Online you can download any of these:
