Help with adding rows to JTable

Could any body help me with the following problem:
I have created form where I use JTable.Initially I should show 5 rows in JTable. User can enter data into the cells.And commit I should store the data in database.
My problem is how to dynamically add rows to JTable as user is entering the data. And how to retain the data in the cells when it is entered.
Right now when user edits a cell and tabs to next one the data in previous cell disappears.
Its Urgent can anybody help me
Thanks in advance
Babu

The number of rows, number of columns, etc, are all determined by the TableModel used in the JTable.
What is the easiest solution is to subclass AbstractTableModel adding methods to support your dynamic row adding/deleting/etc that you need. If you go to the javadoc for JTable, there's a link to a tutorial which contains most of what you need to know.

Help with adding image onclick

Hey everyone,
I am making a simple game in AS3 and need help with adding an image once they have click on something.
On the left of the screen are sentences and on the right an image of a form. When they click each sentence on the left, writing appears on the form. Its very simple. With this said, what I would like to do is once the user click one of the sentences on the left, I would like a checkmark image to appear over the sentence so they know they have already clicked on it.
How would I go about adding this to my code?
var fields:Array = new Array();
one_btn.addEventListener(MouseEvent.CLICK, onClick1a);
one_btn.buttonMode = true;
function onClick1a(event:MouseEvent):void
    fields.push(new one_form());
    fields[fields.length-1].x = 141;
    fields[fields.length-1].y = -85;
    this.addChild(fields[fields.length-1]);
    one_btn.removeEventListener(MouseEvent.CLICK, onClick1a);
    one_btn.buttonMode = false;
    //gotoAndStop("one")
two_btn.addEventListener(MouseEvent.CLICK, onClick2a);
two_btn.buttonMode = true;
function onClick2a(event:MouseEvent):void
    fields.push(new two_form());
    fields[fields.length-1].x = 343.25;
    fields[fields.length-1].y = -85;
    this.addChild(fields[fields.length-1]);
    two_btn.removeEventListener(MouseEvent.CLICK, onClick2a);
    two_btn.buttonMode = false;
    //gotoAndStop("two")

I don't know where you're positioning the button that should enable/disable the checkbox but for "one_btn" let's just say it's at position: x=100, y=200. Say you'd want the checkbox to be to the left of it, so the checkbox would be displayed at: x=50, y=200. Also say you have a checkbox graphic in your library, exported for actionscript with the name "CheckBoxGraphic".
Using your code with some sprinkles:
// I'd turn this into a sprite but we'll use the default, MovieClip
var _checkBox:MovieClip = new CheckBoxGraphic();
// add to display list but hide
_checkBox.visible = false;
// just for optimization
_checkBox.mouseEnabled = false;
_checkBox.cacheAsBitmap = true;
// adding it early so make sure the forms loaded don't overlap the
// checkbox or it will cover it, otherwise swapping of depths is needed
addChild(_checkBox);
// I'll use a flag (a reference for this) to know what button is currently pushed
var _currentButton:Object;
one_btn.addEventListener(MouseEvent.CLICK, onClick1a);
one_btn.buttonMode = true;
function onClick1a(event:MouseEvent):void
     // Check if this button is currently the pressed button
     if (_currentButton == one_btn)
          // disable checkbox, remove form
          _checkBox.visible = false;
          // form should be last added to fields array, remove
          removeChild(fields[fields.length - 1]);
          fields.pop();
          // clear any reference to this button
          _currentButton = null;
     else
          // enable checkbox
          _checkBox.visible = true;
          _checkBox.x = 50;
          _checkBox.y = 200;
          // add form
          fields.push(new one_form());
          fields[fields.length-1].x = 141;
          fields[fields.length-1].y = -85;
          this.addChild(fields[fields.length-1]);
          // save this button as last clicked
          _currentButton = one_btn;
     // not sure what this is
    //gotoAndStop("one")
I'd also centralize all the click handlers into a single handler and use the buttons name to branch on what to do, but that's a different discussion. Just see if this makes sense to you.
The jist is a graphic of a checkbox that is a MovieClip symbol in your library exported to actionscript with the class name CheckBoxGraphic() is created and added to the display list.
I made a variable that points itself to the last clicked button, when the "on" state is desired. If I detect the last clicked button was this button, I remove the form I added and the checkbox. If the last clicked button is not this button, I enable and position the checkbox as well as add the form.
What is left to do is handle the sitation where multiple buttons are on the screen. When a new button is pushed it should remove anything the previous button added. This code simply demonstrates clicking the same button multiple times to toggle it "on and off".

Need help with Pivoting rows to columns

Hi,
I need help with pivoting rows to columns. I know there are other posts regarding this, but my requirement is more complex and harder. So, please give me a solution for this.
There are two tables say Table 1 and Table 2.
Table1
name address email identifier
x e g 1
f s d 2
h e n 3
k l b 4
Table2
identifier TRno zno bzid
1 T11 z11 b11
1 T12 z12 b12
1 T13 z13 b13
2 T21 z21 b21
2 T22 z22 b22
As you can see the identifier is the column that we use to map the two tables. The output should be like below
output
name address email identifier TRno1 zno1 bzid1 TRno2 zno2 bzid2 TRno3 zno3 bzid3
x e g 1 T11 z11 b11 T12 z12 b12 T13 z13 b13
f s d 2 T21 z21 b21 t22 z22 b22
Also we do not know exactly how many TRno's, zno's, etc each value in the identifier will have. There may be only 1 TRNO, zno and bzid, or there may be four.
All the values must be in separate columns, and not be just comma delimitted. There are also other conditions that i have to add to restrict the data.
So, can you please tell me what is should use to get the data in the required format? We are using Oracle 10g. Please let me know if u need any more information

Something like this ?

Help with adding a hyperlink to a button?

We have a simple little site we built in Catalyst and everything works great. The only problem is that we cannot figure out how to add a hyperlink to one of the buttons in the animation. We simply want to be able to click on the button and go to another site (the client's Facebook page specifically). Can anyone provide some insight? Thanks!

Seeing Database Changes Made Internally and Externally
This section discusses the ability of a result set to see the following:
its own changes (DELETE, UPDATE, or INSERT operations within the result set), referred to as internal changes
changes made from elsewhere (either from your own transaction outside the result set, or from other committed transactions), referred to as external changes
Near the end of the section is a summary table.
Note:
External changes are referred to as "other's changes" in the Sun Microsystems JDBC 2.0 specification.
Seeing Internal Changes
The ability of an updatable result set to see its own changes depends on both the result set type and the kind of change (UPDATE, DELETE, or INSERT). This is discussed at various points throughout the "Updating Result Sets" section beginning on , and is summarized as follows:
Internal DELETE operations are visible for scrollable result sets (scroll-sensitive or scroll-insensitive), but are not visible for forward-only result sets.
After you delete a row in a scrollable result set, the preceding row becomes the new current row, and subsequent row numbers are updated accordingly.
Internal UPDATE operations are always visible, regardless of the result set type (forward-only, scroll-sensitive, or scroll-insensitive).
Internal INSERT operations are never visible, regardless of the result set type (neither forward-only, scroll-sensitive, nor scroll-insensitive).
An internal change being "visible" essentially means that a subsequent getXXX() call will see the data changed by a preceding updateXXX() call on the same data item.
JDBC 2.0 DatabaseMetaData objects include the following methods to verify this. Each takes a result set type as input (ResultSet.TYPE_FORWARD_ONLY, ResultSet.TYPE_SCROLL_SENSITIVE, or ResultSet.TYPE_SCROLL_INSENSITIVE).
boolean ownDeletesAreVisible(int) throws SQLException
boolean ownUpdatesAreVisible(int) throws SQLException
boolean ownInsertsAreVisible(int) throws SQLException
Note:
When you make an internal change that causes a trigger to execute, the trigger changes are effectively external changes. However, if the trigger affects data in the row you are updating, you will see those changes for any scrollable/updatable result set, because an implicit row refetch occurs after the update.
Seeing External Changes
Only a scroll-sensitive result set can see external changes to the underlying database, and it can only see the changes from external UPDATE operations. Changes from external DELETE or INSERT operations are never visible.
Note:
Any discussion of seeing changes from outside the enclosing transaction presumes the transaction itself has an isolation level setting that allows the changes to be visible.
For implementation details of scroll-sensitive result sets, including exactly how and how soon external updates become visible, see "Oracle Implementation of Scroll-Sensitive Result Sets".
JDBC 2.0 DatabaseMetaData objects include the following methods to verify this. Each takes a result set type as input (ResultSet.TYPE_FORWARD_ONLY, ResultSet.TYPE_SCROLL_SENSITIVE, or ResultSet.TYPE_SCROLL_INSENSITIVE).
boolean othersDeletesAreVisible(int) throws SQLException
boolean othersUpdatesAreVisible(int) throws SQLException
boolean othersInsertsAreVisible(int) throws SQLException
Note:
Explicit use of the refreshRow() method, described in "Refetching Rows", is distinct from this discussion of visibility. For example, even though external updates are "invisible" to a scroll-insensitive result set, you can explicitly refetch rows in a scroll-insensitive/updatable result set and retrieve external changes that have been made. "Visibility" refers only to the fact that the scroll-insensitive/updatable result set would not see such changes automatically and implicitly.
Visibility versus Detection of External Changes
Regarding changes made to the underlying database by external sources, there are two similar but distinct concepts with respect to visibility of the changes from your local result set:
visibility of changes
detection of changes
A change being "visible" means that when you look at a row in the result set, you can see new data values from changes made by external sources to the corresponding row in the database.
A change being "detected", however, means that the result set is aware that this is a new value since the result set was first populated.
With Oracle8i release 8.1.6 and higher, even when an Oracle result set sees new data (as with an external UPDATE in a scroll-sensitive result set), it has no awareness that this data has changed since the result set was populated. Such changes are not "detected".
JDBC 2.0 DatabaseMetaData objects include the following methods to verify this. Each takes a result set type as input (ResultSet.TYPE_FORWARD_ONLY, ResultSet.TYPE_SCROLL_SENSITIVE, or ResultSet.TYPE_SCROLL_INSENSITIVE).
boolean deletesAreDetected(int) throws SQLException
boolean updatesAreDetected(int) throws SQLException
boolean insertsAreDetected(int) throws SQLException
It follows, then, that result set methods specified by JDBC 2.0 to detect changes--rowDeleted(), rowUpdated(), and rowInserted()--will always return false with the 8.1.6 Oracle JDBC drivers. There is no use in calling them.
Summary of Visibility of Internal and External Changes
Table 12-1 summarizes the discussion in the preceding sections regarding whether a result set object in the Oracle JDBC implementation can see changes made internally through the result set itself, and changes made externally to the underlying database from elsewhere in your transaction or from other committed transactions.
Table 12-1 Visibility of Internal and External Changes for Oracle JDBC
Result Set Type Can See Internal DELETE? Can See Internal UPDATE? Can See Internal INSERT? Can See External DELETE? Can See External UPDATE? Can See External INSERT?

For implementation details of scroll-sensitive result sets, including exactly how and how soon external updates become visible, see "Oracle Implementation of Scroll-Sensitive Result Sets".
Notes:
Remember that explicit use of the refreshRow() method, described in "Refetching Rows", is distinct from the concept of "visibility" of external changes. This is discussed in "Seeing External Changes".
Remember that even when external changes are "visible", as with UPDATE operations underlying a scroll-sensitive result set, they are not "detected". The result set rowDeleted(), rowUpdated(), and rowInserted() methods always return false. This is further discussed in "Visibility versus Detection of External Changes".
Oracle Implementation of Scroll-Sensitive Result Sets
The Oracle implementation of scroll-sensitive result sets involves the concept of a window, with a window size that is based on the fetch size. The window size affects how often rows are updated in the result set.
Once you establish a current row by moving to a specified row (as described in "Positioning in a Scrollable Result Set"), the window consists of the N rows in the result set starting with that row, where N is the fetch size being used by the result set (see "Fetch Size"). Note that there is no current row, and therefore no window, when a result set is first created. The default position is before the first row, which is not a valid current row.
As you move from row to row, the window remains unchanged as long as the current row stays within that window. However, once you move to a new current row outside the window, you redefine the window to be the N rows starting with the new current row.
Whenever the window is redefined, the N rows in the database corresponding to the rows in the new window are automatically refetched through an implicit call to the refreshRow() method (described in "Refetching Rows"), thereby updating the data throughout the new window.
So external updates are not instantaneously visible in a scroll-sensitive result set; they are only visible after the automatic refetches just described.
For a sample application that demonstrates the functionality of a scroll-sensitive result set, see "Scroll-Sensitive Result Set--ResultSet5.java".
Note:
Because this kind of refetching is not a highly efficient or optimized methodology, there are significant performance concerns. Consider carefully before using scroll-sensitive result sets as currently implemented. There is also a significant tradeoff between sensitivity and performance. The most sensitive result set is one with a fetch size of 1, which would result in the new current row being refetched every time you move between rows. However, this would have a significant impact on the performance of your application.

Help With Adding Back Up of Songs & Lists on Re-Installed iTunes v 7.0.2

I have a portable hard drive with a back up of my 10,000 songs. I have to get my Gateway PC laptop serviced as it continues to crash, and so I will need to re-install iTunes v 7.0.2 and then add back my songs from the portable hard drive.
I need help with a couple of questions:
1) Is there a quicker way to add the songs back on to iTunes rather than adding individual files (for songs) and individual folders (for albums)?
2) I have several song lists (some used to make CD's). How can these lists be backed up as well so that I do not have to re-create these lists?
Any advice very much appreciated.

There is a good article on backup here:
http://discussions.apple.com/thread.jspa?messageID=1522195&#1522195
If all your music is in the iTunes Music folder and you have room, just copy the iTunes folder to your external drive.
This will include both your music files and the iTunes library files.
If you music is stored in other places, you need to backup those too. When you restore you need to ensure the full path name is the same.
Life is also much easier if you can keep exactly the same account name if you reinsall windows as the account name is part of the path to My Documents.

Archive applet. Help with adding files to archive, then show.

I need help with this applet: http://pastebin.com/589064
The user is supposed to add, remove and open archives with text in it.
My problem is now the highlited area in the code (the lines with the @@'s).
This button should list all files i have added to the archive, however when i press the button, i only get a numberlisting. eg, if i have added 4 files to the archive I get: 0123
However I want the Joptionpane to show a listing of the files in the archive.
When I press "open" i can choose a file, press add, then open a new file, press add, and then when i click show archive, the filenames of the two files i added, should list through a Joptionpane..as you can see, i've tried, but i'm very unfamiliar with this.

OK..i've done it
check out http://pastebin.com/589268
however, now i'd like to change the code, so that if i try to add to files with the same filename, the applet should show an error message..
How do i do that, please? :-)

Help with adding new song to 2007 iPod shuffle

I have an iPod shuffle from 2007 and just recently went to add new songs to it. Itunes program keeps telling me I have to erase everything and reload w/ new playlist I've added?? Confused, don't remember it working like this last year when I added songs. Any help??

With the 1st and 2nd gen iPod shuffle, it can only be associated with one iTunes library at a time. That has always been the design. It is basically like a mobile playlist for iTunes the library. The 3rd and 4th gen shuffles work more like the "bigger" iPods that have a screen, which is different from the very simple 1st and 2nd gen.
If you previously used this shuffle with a different iTunes library, iTunes is asking if you want to associate the shuffle with the iTunes library you are now using.
Any help??
What do you want to do...?

Help With adding a scrollbar to my applet

This is the source code of my applet.I wat to have an autoscroll on this applet
i think it is usefull if i put here all the code for my project.
======================================================
Class ConsolePanel:
The file defines a class ConsolePanel. Objects of type
ConsolePanel can be used for simple input/output exchanges with
the user. Various routines are provided for reading and writing
values of various types from the output. (This class gives all
the I/O behavior of another class, Console, that represents a
separate window for doing console-style I/O.)
This class is dependent on another class, ConsoleCanvas.
Note that when the console has the input focus, it is outlined with
a bright blue border. If, in addition, the console is waiting for
user input, then there will be a blinking cursor. If the console
is not outlined in light blue, the user has to click on it before
any input will be accepted.
This is an update an earlier version of the same class,
rewritten to use realToString() for output of floating point
numbers..

Hi
I don't understand the exact need you want
you want to add Scrolling facility to your Entire Applet or only for the Textarea Class?
In first case
Create the ScrollPane and add it to the applet contentPane. and put entire components to a Panel and just add it to scroll pane.

Need help with adding a Key flex field to a seeded OAF page

We have a seeded OAF page on which we already have Account Key Flex Field.
Properties of this flex field are:
The ApplShortName - SQLGL
Name - GL#
Type - Key
As per the client requirement, in the KFF screen, we have disabled the seeded structure for Accounting Flexfield and created a custom structure.
Our custom structure for the KFF is displayed correctly on the OAF page.
But now the requirement is to add a new KFF on the OAF page which is duplicate of the existing KFF, along with the existing KFF field; the structure and segments are same. Only difference being the display name of the existing KFF field is Account; the new one needs to be Tax structure.
Using personalization we added a new flex item and added the properties same as the existing KFF.
ApplShortName - SQLGL
Name - GL#
Type - Key
But the page is giving following error:
The data that defines the flexfield on this field may be inconsistent. Inform your system administrator that the function: KeyFlexfieldDefinitionFactory.getStructureNumber could not find the structure definition for the flexfield specified by Application = SQLGL, Code = GL# and Structure number =
We tried options like compiling the flexfield definition, but the error persists.
Any help in this regard is highly appreciated.
Regards,
Kiranmayi.

Hi,
Please check whether your key flex structure is frozen or not. If now please freeze it and re compile and try.
This may helps too
