Text Area can not show a mass of chars

I create a textArea, and assign million chars to the Text property. The flex application is freezing for minutes.
Could some one give me an advice to make textArea display mass chars effectively, or is there a way to append text at the end of the textarea instead of displaying mass chars one time?
I use Flex SDK 3.4 and Flex Builder 3.

You will probably have to implement some form of virtualization. In other words, only display the section of text that is currently visible. This is likely to be challanging with the standard text controls, so you I imagine you will need to develop something custom. The text layout framework would probably provide the best starting point:

Note that it is player 10 only.

I don't think LR4 adjustments can be directly sent to CS4, because CS4 cannot interpret LR4's new processing engine.
I think you have to use Edit In... and create a TIF or PSD and send those to CS4

Can not show applet in jeditorpane

Hi,
I want to load a Web page which contains an applet into a JeditorPane, but I found the applet can not show in the editorpane.
I use the following statement to create a JEditorPane
JEditorPane htmlpane = new JEditorPane("http://sulu.informatics.indiana.edu/6S/network/");
The static text is showing, but the applet graph is always missing. Do I need to do something else? Please help me!

JEditorPane's abilities to show HTML are very limited. It doesn't support CSS, JavaScript, applets and many other things. You'll need a real browser component for that.

SetText() works for one text area but not for another

I am student new to java so forgive me if I'm making an obvious mistake. I have a GUI with 3 tabs. Two tabs have a text area in each in them and an action listener tells the textarea what to print. The problem is one text area works and the other doesn't. they are declared in the same way so I can't see why the problem occurs.

If you have copied and pasted code for the second one, it is possible that you are setting text for the first text area at both the places. Check if you are calling the setText method on both the text areas and not the same one twice.

Payment Order, Payment transaction area can not be posted

Hi,
While creating a Payment order for a current account, we are recieving the following error:
'Payment Order, Payment transaction area can not be posted' and 'Error determining the number range'.
As a result Payment order is not getting created.
Number range interval has already been checked and assigned to the relevant Payment Transaction Area.
Please suggest the possible options to look for the solution.
Thanks
Shefali

Hi Shefali ,
From the description you gave, it looks like the problem is related to number range only . Can you please double check if the number range you are mentioning is assigned to same Payment Transaction Area which is being used .
Also if possible post the long text with message ID if available.
Regards
Ravi

My Startup Disk can not show in Finder.

My Startup Disk can not show in Finder.but it can be used in OSX normally.
So can I put it back to Finder?

If the startup disk is for Mac OS 9, neither MacBook nor PowerMac G5 can boot into 9. Only the PowerMac G5 can use Mac OS 9 in Apple menu -> System Preferences -> Classic.
Please be more detailed what sort of Startup Disk you are talking about, which operating system, and which machine this is a problem with.

Why this tree can not show on the Applet?

hi, all, I try to create a java Applet show a tree, this following code has no error, but the tree can not show on the Applet, can any one tell me why? thanks!
<code>
import java.awt.*;
import java.applet.Applet;
import java.awt.event.*;
import java.util.*;
import javax.swing.*;
import javax.swing.tree.*;
import java.awt.dnd.*;
public class AppletApp extends Applet {
     Date myDate;
     protected JTree m_tree = null;
     protected DefaultTreeModel m_model = null;
     protected JTextField m_display;
     public void init() {
     public void paint(Graphics g) {
          DefaultMutableTreeNode root = new DefaultMutableTreeNode("root");
          DefaultMutableTreeNode node1 = new DefaultMutableTreeNode("node1");
          root.add(node1);
          node1.add(new DefaultMutableTreeNode("sub1_1"));
          node1.add(new DefaultMutableTreeNode("sub1_2"));
     public static void main(String arg[]) {
          JFrame myFrame = new JFrame();
          Container contentPane = myFrame.getContentPane();
          contentPane.setLayout(new GridLayout(1,2));
          AppletApp app = new AppletApp();
          contentPane.add(new JScrollPane(app), BorderLayout.CENTER);
          myFrame.addWindowListener (new WindowAdapter() {
               public void windowClosing(WindowEvent e) {
                    System.exit(0);
          app.init();
          app.start();
          myFrame.setSize (400,400);
          myFrame.setVisible(true);
</code>

Not quite sure what you are trying to do, but if you move the code from the paint() method into the init() method (then delete your paint() method), then add one new line to the init() method (after the code you just inserted) that reads:
getContentPane().add(new JTree(root));
- You should at least see a tree!

My iphone 5 for some reason can receive calls, send & receive texts but can not call out

My iphone 5 for some reason can receive calls, send & receive texts but can not call out

I am not sure if this issue is going to help you but lets give it a try.
I know that where im from, which is the Netherlands, I am not able to sent e-mails from my iPhone or any other mobile device by using 3G or a random WIFI acces point. The provider only allowes you to sent e-mails when you are connected to a network of there own. Which means if you have provider "101" and your email settings are set up for this provider in your iPhone but your using the network of a friend of yours which is provider "202" you cannot sent emails from his network. Though you can receive them you may not sent.
As I said, I am not aware if this issue is the same for you totaly depents on the country and provider your using.
