Tried using array, still no joy, why isnt it working?
Hi, followed your advise and changed to array. i now get a java.lang.NullPointerException. Code is as follows:
static XYRMIClient ORBLinks[];
for (int q = 0; q < count; q++){
ORBLinks[q] = new XYRMIClient(this, iparray[q], Port, Message);
The object is being created, so why is it saying null pointer? any help very much appreciated
i should have said, this is a follow up to my previous post, and the code compiles, i get the null pointer when running.

I cannot install adobe flash onto my mac, whenever the installation box appears it asks for a password! I have entered my apple ID password and any other password I use, but still no joy! Any advice?
Exactly where are you getting your Flash from? It is quite free from the maker, no password needed.
http://get.adobe.com/flashplayer/
However, if you fell for a trap and were lured into a fake site to rob you of your Apple ID credentials, I suggest you change your passwords immediately. -

Before posting gui issues, please use a newer API, even jdk1.1 would be fine, anything would be better than what your using.
you wrote: I dont care if its javax.swing or

I would also gather from this statement that your attitude could be one of your other issues. -

I have Win7 64 bit and when I tried to install the latest I-Tunes update it failed and told me to reinstall. I attempted the reinstall and got the same result. I have attempted this several times already even after following the recommendations from Apple website to correct this problem. I have installed numerous updates for I-Tunes and this is the first one to fail. Is there a fix in the works from Apple for this? I believe the update is flawed and should be re-evaluated by Apple and this update re-issued with different version #.

Look, I have SERIOUS problems with my MacBook Pro, a computer that was given to me by Apple to replace a MacBook Pro that was defective from day one. Now this fabulous machine from Apple is totally messed up since the upgrade to Mavericks. I've talked with "Senior Advisors" until I'm blue in the face, but NOTHING fixes this machine. So can SOMEONE out there PLEASE HELP ME?
I live in rural Ireland, I cannot drive because I was in a coma at years ago (although I could drive if I had 10+ DUIs), I'm over two hours from the closest Apple Authorized Repair, I'm physical disablled and mobility impaired, and I'm terminallly ill. So from where I stand, I really don't have time to sit around and wait. It took Apple 11 months to sort out the problem with my original MacBook Pro; I don't HAVE 11 months to wait for this problem to be fixed, but I've been waiting now for over 2 months, and my death clock is ticking.
PLEASE HELP ME!!! TIME IS OF THE ESSENCE BECAUSE I'M DYING!!! Now is that clear enough for you, Apple?
Sincerely,
Kathleen Trevena-Ruane
<Personal Information Edited by Host>Have you tried to erase your drive and reinstall the OS - you should use recoery (hold Command + R keys while restarting). Since the items in the menu bar are part of the system, a clean reinstall of the system should take care of it.
As it is dangerous to post private information in a public forum, I will ask the hosts to remove it.
FWIW, we are all other users here - you are not addressing Apple. -
I just download the 4.0 version and my scroll pad on my laptop won't work. I have to use my arrow keys or the side bar on the side. The scroll pad works with Internet Explorer and anywhere else just not with Firefox's newest version.
This one is easy. The shortcut is for the old iTunes, that is why it won't work.
I assume you are using Windows.
If so, go to the bottom left of your screen and click the start button. Go up to programs and hold your cursor over it. A list of all your programs should pop up to the right. Move the curso over to iTunes. There should be an "about iTunes" and an iTunes logo there. Right click on the iTunes logo and click create shortcut (you can also just drag it out to your desktop). That will give you a desktop shortcut for your new version. -
After a big loss of out-pulled hair here is the code:
setInterval() calls getNewMess function but it happens
nothing with onNewMess function.
Instead, if i click refresh-button, it gives me result
correctly.evt.target._parent
is just using the event argument that is dispatched to and
therefore received by your listener function. It is dispatched/sent
by your button component instance. The event object from components
- in as2 - normally contains at least two properties. A type
property... in this case that's "click" , because its a click event
and a target property. The target property is a reference to the
component instance from which the event originated. It can be
particularly useful if you have one listener handling events from
many sources. So.....
evt.target._parent is referring to the container clip of the
instance that sent the event. i.e. The _parent of the button in
this case.
That's why I replaced it with t (=this) which is a reference
to the timeline that the button is running in. Now it doesn't need
to get that reference from checking the _parent of the evt.target
property from the evt argument. Which means the argument that the
newMess function receives can be ignored and its no longer reliant
on it. Sounds confusing but once you "get" it, it all makes sense.
Eventually, lol.
And of couse you don't need to have a button if you don't
want one. -

Why isn't this formail cgi working?
http://megacyberteck.com/contact.html
Thanks for helping>
http://megacyberteck.com/contact.html
>
the server is treating the script like a TEXT file.
http://megacyberteck.com/formmail.cgi
Properly working, that version of formmail.cgi script will
give a copyright
and "missing recipient" error message when you load it
directly into the
browser.
as the others have said- most hosts require cgi files to be
in a specific
cgi-bin directory for them to be allowed to execute.
and- if on Apache server, you have to give the file
permission to execute,
as the README instructions detail on chmod'ing the file to
755.
http://uptime.netcraft.com/up/graph?site=megacyberteck.com
okay, it's Apache/Unix
See your host's FAQ/Support section.
Also, it's fairly common for the cgi-bin folder to be in the
private top
level root of your hosting. It's also very common on that
type of hosting
for a "formmail-clone" script to already be preinstalled and
ready for use.
If your hosting has a control panel or CPanel, go to it and
look around. -

Why isnt this working? add container to frame..
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class MortgageCalcFrame {
private static void createAndShowGUI() {
//Create and set up the window.
JFrame frame = new JFrame("Mortgage calculator");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
// Add's a container in the frame
Container content = new Container();
frame.getContentPane().add(content, BorderLayout.SOUTH);
JButton btn = new JButton("test");
content.add(btn, BorderLayout.EAST);
JTextField input = new JTextField(5);
frame.getContentPane().add(input, BorderLayout.CENTER);
//Display the window.
frame.pack();
frame.setVisible(true);
public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
}Well the problem you got is that the layout of a Container is null. You've got several options here.
1. You set a layout for your container like this
Container content = new Container();
content.setLayout(new FlowLayout());2. You use a different container that inherits from container like Panel or JPanel since this one already got a FlowLayout set.
Panel content = new Panel();or
JPanel content = new JPanel(); //better since you're currently mixing Swing components and AWT. -

Have you tried:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
