URGENT!!! Help me about JTable, Please.
I have a JTable, it is contained into JScrollPane and I show JScrollPane on a Dialog. When I use JTable, I have some problem :
+ How can I change the data in a JTable, change quantity of columns, quantity of rows (example : I can increase or decrease quantity of columns or rows at the run time).
if you have the JDK documentation installed than search for JTable, you will get everything on tables there, no offence but it sounds really stupid that you cant get what you want coz according to your question, i have seen more than enough information.

URGENT !!! Help me about JTable.
I want to make a program with swing. I use class JTable to show my datum and I have a problem :
When I create an Object of class JTable (with a Vector , you can review constructor of JTable), I add it into a Scroll (JScrollPane class) and then I add whole into a Dialog (JDialog). My main problem is :
- When Dialog is showed, it contained Table with ScrollPane. On Table, there is some datum and now, I want to clear old datum and show new datum on Table. How can I do that???
Thanks !!!Instead of passing a Vector to your JTable constructor, do:
// The second arg is the names of the columns. Adjust the number and names as required.
DefaultTableModel model = new DefaultTableModel(yourVector,
new String[]{"Names", "For", "The", "Columns"});
JTable table = new JTable(model);When you want to change the data:
// 2nd are is the column names again.
model.setDataVector(newData, new String[]{"New", "Column", "Names", "(or old ones)"}); -
PLEASE could someone help me look at this and see why the color of my data in a jtable cell is niot turning red when I press enter

Urgent help with If statement please!
HI Everyone
Was wondering if anyone can tell me why flash seems to be
ignoring my If Statements, every time I try to use one it ignores
the condition and just actions the command. Its driving me crazy.
I'm sure I must be doing something wrong I just can't work it out.
I've put;
on (release) {
if ((_root.eyeshadow = "Pink") && (_root.lipy =
"Pink")) {
_root.correct._alpha =100;
It seems to just action the _root.correct._alpha = 100;
even when a different colour is selected.
I was wondering can flash read a variable from another
script, because if not it will not know what eyeshadow and lipy
are. I dont get any error messages though.
Please help somebody!
Thank you,
Stacy.x.Thank you that appears to have made the if statement work,
but now i have another problem.
It doesn't seem to acknowledge wether these selections have
been selected.
I have put in the code for the pink eyeshadow;
on (release) {
_root.eyeshadow2._alpha =0;
_root.eyeshadow1._alpha = 100;
eyeshadow == "Pink";
the same code is in all the other selections, with the name
variations.
any ideas?
.x. -

URGENT HELP NEEDED FOR JTABLE PROBLEM!!!!!!!!!!!!!!!!!
firstly i made a jtable to adds and deletes rows and passes the the data to the table model from some textfields. then i wanted to add a tablemoselistener method in order to change the value in the columns 1,2,3,4 and set the result of them in the column 5. when i added that portion of code the buttons that added and deleted rows had problems to function correctly..they dont work at all..can somebody have a look in my code and see wot is wrong..thanx in advance..
below follows the code..sorry for the mesh of the code..you can use and run the code and notice the problem when you press the add button..also if you want delete the TableChanged method to see that the add button works perfect.

}There are too many mistakes in your program. It looks like you are new to java.
Your add and delete row buttons are not working because you haven't registered your action listener with these buttons.
I have modifide your code and now it works fine. Just put some validation code for the textboxes becuase it throws exception when user presses add button without entering anything.
Here is the updated code: Do the diff and u will know my changes

Urgent Help is needed : Experts please help
Does modification of Transfer rule and update rule require data deletion from all the dependent data targets?
Hi Experts,
Two new key figures have been added in data source and subsequently in transfer rules, updated rules, ODS and cubes there in data flow.
The changes are supposed to move in production on this weekend. I am afraid; does this activity require data deletion from the data targets before moving the transports?
With out deletion of the data can these transports be moved in prod?
Please reply with your valuable advice.
Points will be rewarded.
Thanks,
BW USERhi,
hope u might have to do changes in the cube and ods also rite?
and you need to have data for the added key figure in the cube/ods for the already existing records in the cube/ods.for this you copy content in other cube/ods and do delete and reload the data to the new changed cube/ods.

Urgent Help on JAXB Validation - Please Help
I have an application that needs validation before marshalling a content tree. If the tree is not valid, I need to marshall the tree and look at the problem in the XML file itself.
If it's a valid XML file, then continue as usual...
These is the pseudo code.. But don't know if I can implement it with JAXB or not....And how to implement it..
populate XML tree
check if the tree is valid or not
if it is valid continue processing
if not valid, marshall the tree into an XML file and analyze the
problem
Any input is welcome...
Thanks in advance..svenkatesh s, thanks for your reply. In addition to your suggestion,

There are a couple of things that you can do yourself before taking your machine into an Apple Store or an AASP... download and run an application named Rember that will run a RAM test for you - let it run for a couple of hours or even overnight. If it turns out that your RAM is faulty, Rember will let you know. If it is faulty, then you have a couple of options - replace the RAM yourself or (particularly if you're under warranty still) take the machine to an Apple Store or AASP and have them replace the RAM.
If Rember finds no fault with the RAM, then you'll need to take it into an Apple Store/AASP and get a free diagnosis on the machine. Three beeps do usually indicate faulty RAM, but if it tests good with Rember you likely have another problem - it could be something as simple as the RAM, somehow, not seated correctly or signs of another hardware problem.
Run Rember first... call back with results.
Good luck,

i was updating software and suddenly my IPHONE started asking for I tunes on mobile screen , how can i get by screen back or How i can restore without loosing data , I m more worried about data , Please help in resolutio
What exactly are you seeing on the phone's screen ? If the iTunes icon and cable then the phone is in recovery mode, in which case it's too late to take a new backup or to copy any content off the phone - you will have to connect the phone to your computer's iTunes and reset it back to factory defaults, after which you can restore to the last backup that you took or just resync your content to it

sir/mam,i am new for workflow,will any one give me guidence for how i will start with workflow ..please help me about this topic....?
Somnath,
Your question is very vague. What do you mean by new to Workflow?
Workflow can be defined as
A workflow is a reliably repeatable pattern of activity enabled by a systematic organization of resources, defined roles and mass, energy and information flows, into a work process that can be documented and learned. Workflows are always designed to achieve processing intents of some sort, such as physical transformation, service provision, or information processing.
Workflows are closely related to other concepts used to describe organizational structure, such as silos, functions, teams, projects, policies and hierarchies. Workflows may be viewed as one primitive building block of organizations. The relationships among these concepts are described later in this entry.

please help me about answer security question in my apple id because im forgot for my answer, in my apple id no have for change answer, tell me for this please because i love my iphone.
<Email Edited by Host>You need to ask Apple to reset your security questions; this can be done by clicking here and picking a method, or if your country isn't listed, filling out and submitting this form.
They wouldn't be security questions if they could be bypassed without Apple verifying your identity.
