Repeating JList
i having problem when press add button.. instate of adding a new list with the same element.. i want the quantity to become 2..
//listModel is the DefaultListModel
if (e.getSource() == addBtn) { //when press add button
for (int i = 0; i < listModel.getSize(); i++){
if (listModel.elementAt(i) == listModel.lastElement()){ //a loop to check all the list with the last list element
listModel.removeElementAt(i); // if equal delete the list
quantity++;
listModel.addElement("bla, bla" + quantity); // then add a new list
}sry, just learn java a few month ago and i cant get other help.. this is the best method i can think of.. if got other method can post the link to it.. Thanx alot
if (listModel.elementAt(i) == listModel.lastElement())Don't use "==" to compare Objects. Use the equals(...) method.

Moving items up and down in a JList
Hello I posted this query in the wrong forum and so now I am trying to correct the problem Here is the link
http://forum.java.sun.com/thread.jspa?threadID=5267663&tstart=0
Hi-
I have a problem with moving selected items up and down in a JList..
When I select an item in the JList and press ctrl + (the up or down arrow key),
I want the selected item to move up (or down).
My code works. That is to say it does what I want, only the highlighted item does not correspond to the selected item.
When I move an item up I would like it to remain selected, which I guess it is as repeated moves will move the item.
But it does not appear to be working. because the highlight is above the selected item when moving up and below the selected item when moving down.
Here is my code:
public class MyClass implements MouseListener,KeyListener
private JList linkbox;
private DefaultListModel dlm;
public List<String> Links= new ArrayList<String>();
private String Path;
private JScrollPane Panel;
public MyClass (String path,JScrollPane panel){
super();
Path=path;
Panel=panel;
//Populate the ArrayList "Links" etcetera.
dlm = new DefaultListModel();
linkbox = new JList(dlm);
for(int k=0;k<Links.size();k++){
dlm.addElement(Links.get(k));
public void keyPressed(KeyEvent e) {
System.out.println("You pressed "+e.getKeyCode());
if(e.getKeyCode()==38&&e.getModifiers()==KeyEvent.CTRL_MASK){
Link sellink =linkbox.getSelectedValue();
MoveUP(sellink);
if(e.getKeyCode()==40&&e.getModifiers()==KeyEvent.CTRL_MASK){
Link sellink =get(linkbox.getSelectedValue();
MoveDown(sellink);
private void MoveUP(Link link){
int pos=-1;
for(int p=0;p<Links.size();p++){
Link l=Links.get(p);
if(l.indexOf(link)==0){
pos=p;
break;
if(pos!=-1&&pos>0){
Links.remove(link);
Links.add(pos-1,link);
dlm.removeAllElements();
for(int k=0;k<Links.size();k++){
dlm.addElement(Links.get(k));
Panel.setViewportView(linkbox);
linkbox.setSelectedIndex(pos-1);
private void MoveDown(Link link){
int pos=-1;
for(int p=0;p<Links.size();p++){
Link l=Links.get(p);
if(l.indexOf(link)==0){
pos=p;
break;
if(pos!=Links.size()-1&&pos>0){
System.out.println("pos= "+pos);
Links.remove(link);
Links.add(pos+1,link);
dlm.removeAllElements();
for(int k=0;k<Links.size();k++){
dlm.addElement(Links.get(k));
Panel.setViewportView(linkbox);
linkbox.setSelectedIndex(pos+1);
}And here is a compileable version...

}Now for some reason this works better.
I notice that the highlight does follow the selection but there is also something else there.
Still in my original version the highlight seems to appear where the dotted lines are?
There seems to be dotted lines around the item above or below the selected item (depending on whether you are going up or down).
Any thoughts at this point would be appreciated.
-Reg.
Can anyone explain to me why this is so and if it can be fixed?
If any one can help I would be grateful,
-RegYou seem to be making a genuine effort. Key Bindings like anything else involves getting familiar with the code and the idiosyncrasies involved and just playing with the code yourself. To get you started, if the JList were called myList I'd do something like this for the up key:
KeyStroke ctrlUp = KeyStroke.getKeyStroke(KeyEvent.VK_UP, InputEvent.CTRL_DOWN_MASK);
myList.getInputMap().put(ctrlUp, "Control Up");
myList.getActionMap().put("Control Up", new AbstractAction()
public void actionPerformed(ActionEvent e)
// do stuff to move your item up
});Please read the tutorial for details, explanation, etc... -

Since installing LTR 5.4, which I've now upgraded to 5.6, I've encountered repeated slowness and malfunctions in operations, especially when using the Compare View function and the Tab key to open and close the right and left side panels. Such problems never arose during two years of using LTR-4 and nothing else has changed on my computer. I have a pretty simple system with only a few plug-ins, which are usually not in operation. I have 12GB of RAM in my Windows 7 PC. I could illustrate these problems with screen shots if you would tell me how to submit screen shots. Otherwise I will try to describe the problems in words.
The problem is clearly cumulative, growing worse as usage time passes. Compare View feature gradually slows down and eventually seems to choke as my work session proceeds. If I Exit LTR and re-enter and start all over, things will work normally for maybe 30 minutes, but then the Compare View feature begins to become very slow to respond. In a recent example with my screen full of thumbnails in Library mode I highlighted two images to compare. LTR started to open the Compare View screen by first having the top row of thumbnails disappear to be replaced by the "SELECT" and "CANDIDATE" words in their spaces (but no images), but Compare View never succeeded in gaining control of the screen. After some seconds the top row of thumbnails reasserted its position and the Compare View windows disappeared. But LTR kept trying to bring them back. Again the top row of thumbnails would go away, Select and candidate would reappear, try again, and give up. This went on for at least 2-3 minutes before I tried to choose File and Exit, but even that did not initially want to respond. It doesn't like to accept other commands when it's trying to open Compare View. Finally it allowed me to exit.
To experiment I created a new catalog of 1100 images. After 30-40 minutes, the Compare View function began to operate very slowly. With left and right side panels visible and two thumbnails highlighted, hitting Compare View can take half a minute before the two mid-size images open in their respective SELECT and CANDIDATE windows. When the side panels are open and two images are in the Select/Candidate spaces, hitting the Tab button to close the side panels produces a very delayed response--25-30 seconds to close them, a few more seconds to enlarge the two images to full size. To reverse the process (i.e., to recall the two side panels), hitting Tab would make the two sides of the screen go black for up to a minute, with no words visible. Eventually the info fields in the panels would open up.
I also created a new user account and imported a folder of 160 images. After half an hour Compare View began mis-placing data. (I have a screen shot to show this.) CANDIDATE appears on the left side of SELECT, whereas it should be on the right. The accompanying camera exposure data appears almost entirely to the left of the mid-screen dividing line. Although the Candidate and Select headings were transposed, the image exposure data was not, but the data for the image on the right was almost entirely to the left of the line dividing the screen in two.
Gurus in The Lightroom Forum have examined Task Manager data showing Processes running and Performance indicators and they see nothing wrong. I could also send screen shots of this data.
At this point, the only way I can process my images is to work 30-40 minutes and then shut down everything, exit, and re-start LTR. This is not normal. I hope you can find the cause, and then the solution. If you would like to see my screen shots, tell me how to submit them.

Repeating a group element on each page of a report.
I have a report where I need to repeat a group element on each page. The element is from the first group in the data. It is in the center group. Currently, the values from this group only print when the group changes. Everything I try does not work. Does anyone have any ideas. I am attaching a sample of the data. Along with the rtf document. I am using the BI Publisher plug in in Word to create the template.

Hi,
You should add a first level of grouping in your subreport on a fake formula field with a constant value. Put your header and footer information in this group header and footer. In the group option make sure to check the "repeat group header on each page option".
This group will act as a page header + footer within your subreport.
good luck!

XML INVOICE Report RAXINV, Taxline is repeating for each invoice line
Hi Tim
Thanks a lot for your blog
Greeting !!
I have successfully created XML report for AR invoice Printing learning from your blog but stuck to a problem , whenever Invoice is having multiple lines ,say 20, then for each invoice line there is tax line printing 20 times like this:
PART NO.| CUSTOMER PART#/DESCRIPTION | UNIT PRICE | QUNTITY|
A123 | 34 WELD-ROD | 52 | 22 |
Tax Exempt @ 0.00
A234 | 238-AL WIER | 63 | 55 |
Tax Exempt @ 0.00
........ Assume there are 20 lines then tax line also repeating 20 times which i don't want .It should get printed only once if it is same
pls help me to achieve this
Thanks
RahulThanks Tim for Your Instant reply.
I have gone through your duplicate line elimination but my requirement is not this
I'll explain it, I am using LINE_DESCRIPTION tag for printing item description and this tag have two value for it, when the LINE_TYPE =LINE then LINE_DESCRIPTION tag is printing the line description and if LINE_TYPE =TAX
then LINE_DESCRIPTION tag is printing the taxline information. Now if I have 20 lines in Invoice then the tax line will also repeat for 20 times, and if i use duplicate line elimination logic and I have same item it'll not print that item, some times whole invoice become blank.
So I want to print 20 lines and out of that 15 lines are have same tax rate then it should print once at the end of 15th line and for remaining 5 lines if tax rate is different for each line then it should print at the end of each line (5lines)
In the linetreevariable i used <xsl:variable xdofo:ctx="incontext" name="invLines" select=".//G_LINES [LINE_TYPE!='FREIGHT']"/> i.e. I want only line type=LINE and TAX
Thanks

[bdb bug]repeatly open and close db may cause memory leak
my test code is very simple :
char *filename = "xxx.db";
char *dbname = "xxx";
for( ; ;)
DB *dbp;
DB_TXN *txnp;
db_create(&dbp,dbenvp, 0);
dbenvp->txn_begin(dbenvp, NULL, &txnp, 0);
ret = dbp->open(dbp, txnp, filename, dbname, DB_BTREE, DB_CREATE, 0);
if(ret != 0)
printf("failed to open db:%s\n",db_strerror(ret));
return 0;
txnp->commit(txnp, 0);
dbp->close(dbp, DB_NOSYNC);
I try to run my test program for a long time opening and closing db repeatly, then use the PS command and find the RSS is increasing slowly:
ps -va
PID TTY STAT TIME MAJFL TRS DRS RSS %MEM COMMAND
1986 pts/0 S 0:00 466 588 4999 980 0.3 -bash
2615 pts/0 R 0:01 588 2 5141 2500 0.9 ./test
after a few minutes：
ps -va

2615 pts/0 R 30:02 689 2 156561 117892 46.2 ./test
I had read bdb's source code before, so i tried to debug it for about a week and found something like a bug:
If open a db with both filename and dbname, bdb will open a db handle for master db and a db handle for subdb,
both of the two handle will get an fileid by a internal api called __dbreg_get_id, however, just the subdb's id will be
return to bdb's log region by calling __dbreg_pop_id. It leads to a id leak if I tried to open and close the db
repeatly, as a result， __dbreg_add_dbentry will call realloc repeatly to enlarge the dbentry area, this seens to be
the reason for RSS increasing.
Is it not a BUG?
sorry for my pool english :)
Edited by: user9222236 on 2010-2-25 下午10:38I have tested my program using Oracle Berkeley DB release 4.8.26 and 4.7.25 in redhat 9.0 (Kernel 2.4.20-8smp on an i686) and AIX Version 5.
The problem is easy to be reproduced by calling the open method of db handle with both filename and dbname being specified and calling the close method.
My program is very simple:
#include <stdlib.h>
#include <stdio.h>
#include <sys/time.h>
#include "db.h"
int main(int argc, char * argv[])
int ret, count;
DB_ENV *dbenvp;
char * filename = "test.dbf";
char * dbname = "test";
db_env_create(&dbenvp, 0);
dbenvp->open(dbenvp, "/home/bdb/code/test/env",DB_CREATE|DB_INIT_LOCK|DB_INIT_LOG|DB_INIT_TXN|DB_INIT_MPOOL, 0);
for(count = 0 ; count < 10000000 ; count++)
DB *dbp;
DB_TXN *txnp;
db_create(&dbp,dbenvp, 0);
dbenvp->txn_begin(dbenvp, NULL, &txnp, 0);
ret = dbp->open(dbp, txnp, filename, dbname, DB_BTREE, DB_CREATE, 0);
if(ret != 0)
printf("failed to open db:%s\n",db_strerror(ret));
return 0;
txnp->commit(txnp, 0);
dbp->close(dbp, DB_NOSYNC);
dbenvp->close(dbenvp, 0);
return 0;
DB_CONFIG is like below:
set_cachesize 0 20000 0
set_flags db_auto_commit
set_flags db_txn_nosync
set_flags db_log_inmemory
set_lk_detect db_lock_minlocks

Repeated Timeouts and "Lost" Interruptus
Hello,
At the risk of repeating an often-asked question, has anyone noticed particularly bad download speeds over the last two days? I have been attempting to download a single standard-definition episode of a TV show over a total of approximately seven hours. I've ruled out network problems; I am on a good DSL line and can download from other sources without difficulty. I have also been able to download much larger files from iTunes in a fraction of the time.
Thanks...

All I ever get is "We were unable to perform your request. Please try again." SEARCH on header text, like Sender and Subject works fine, but apparently Verizon QA has never tested the other options on large mail inboxes.
I'm pretty forgiving and undersrtanding of minor glitches and shortcomings in software, but Verizon Webmail is one of the most unreliable utilities that I've ever encountered from a large company with a huge customer base. -
How can I delete repeats in my iPhoto library without going one at a time?
I have been trying to clean up my iphoto library, and find that many of my imports have been repeated in different places. Is there a way to clean out repeat photos so there aren't so many of the same ones without having to do so one at a time?
You can use any one of these applications to identify and remove duplicate photos from an iPhoto Library:
iPhoto Library Manager - $29.95
Duplicate Cleaner for iPhoto - free - was able to recognize the duplicated HDR and normal files from an iPhone shooting in HDR.
Duplicate Annihilator - $7.95 - only app able to detect duplicate thumbnail files or faces files when an iPhoto 8 or earlier library has been imported into another.
PhotoSweeper - $9.95 - This app can search by comparing the image's bitmaps or histograms thus finding duplicates with different file names and dates.
PhotoDedupo - $4.99 (App Store) - this app has a "similar" search feature which is like PhotoSweeper's bitmap comparison. It found all duplicates.
DeCloner - $19.95 - can find dupicates in iPhoto Libraries or in folders on the HD.
Some users have reported that PhotoSweeper did the best in finding all of the dups in their library: i photo has duplicated many photos, how...: Apple Support Communities.
If you have an iPhone and have it set to keep the normal photo when shooting HDR photos the two image files that are created will be duplicates in a manner of speaking (same image) but the only diplicate finder app that detected the iPhone HDR and normal photos as being duplicates was PhotoSweeper. None of the other apps detected those two files as being duplicates as they look for file name as well as other attributes and the two files from the iPhone have diffferent file names.
iPLM, however, is the best all around iPhoto utility as it can do so much more than just find duplicates. IMO it's a must have tool if using iPhoto.

How can I repeat a for loop, once it's terms has been fulfilled???
Well.. I've posted 2 different exceptions about this game today, but I managed to fix them all by myself, but now I'm facing another problem, which is NOT an error, but just a regular question.. HOW CAN I REPEAT A FOR LOOP ONCE IT HAS FULFILLED IT'S TERMS OF RUNNING?!
I've been trying many different things, AND, the 'continue' statement too, and I honestly think that what it takes IS a continue statement, BUT I don't know how to use it so that it does what I want it too.. -.-'
Anyway.. Enought chit-chat. I have a nice functional game running that maximum allows 3 apples in the air in the same time.. But now my question is: How can I make it create 3 more appels once the 3 first onces has either been catched or fallen out the screen..?
Here's my COMPLETE sourcecode, so if you know just a little bit of Java you should be able to figure it out, and hopefully you'll be able to tell me what to do now, to make it repeat my for loop:

}Hey Vimsie, try resetting a dead apple and see what happens. -
I have 2 calendars set up for my work schedule, a "night shift" and "day shift" calendar. I've set up repeating events fro Fri/Sat/Sun 3-11pm "night shifts" and Mon/Tues 7am-3pm "day shifts". But lets say for example that I swap shifts and instead of working nights on Saturday like I normally would, I am now working days. I want to change that in my calendar. When I go to change the event, if i change the TIME it asks if i want to change all event or ONLY this event. no problem....just this single event. but when i go to change the event from the "night shift" calendar to the "day shift" calendar, it changes ALL the repeating events, and not just that one single event. can anyone help with this??? am i doing something wrong? is there a way to do this or not with the new iCal program??? i used to do this and never had any problems. Thank you!
You need to follow iPhoto terms since we only know what you tell us
what are you calling folders - in iPhoto folders can not hold photos - albums hold photos and folders hold albums or other folders
The basic default view of photo is by event (iPhoto '08 and later)
Exactly what you you trying to do?

High school block schedule repeating events
I'm a high school teacher looking forward to the upcoming fall schedule. I teach at a school where even period and odd period classes are taught on alternate days and I teach only odd schedule classes. So, one week the class is taught on Mon, Wed, Fri and the next week it is Tu and Th except for weeks that have holidays. What is the best way to use repeating events and make up the schedule for this semester (ending 1/28/08 so I also know at a glance what days I'm available to substitute for other instructors?

How can I set an event to repeat on a week day rather than a numerical day of each month?
How can I set an event to repeat on a week day rather than a numerical day of each month? I see an option at the bottom of the repeat window .... but I cannot use it. Actually, when I try it freezes up my Calendar.

Standard def STB repeatedly blacks out for a second or 2
A site search on "black out" does not turn up a similar issue, of course it may be my search skills are lacking.
New subsciber since Sep 2010. I have 3 boxes, 2 standard QIP2500 phase 3 (basement/MBR) and 1 hi-def (LR). Hi def TV in MBR, standard in other 2. Both standards would on occassion 'black out' for just a second or 2 ever since original install. No problem with the hi-def. One standard is wired with coax, one with s-video, the hi-def with HDMI. When the black out occurs, the screen will freeze for an instant, then the screen goes black, then it comes back. The information on the box does not black out, the TVs don't power-off and restart. It's just the screen goes blank and then comes back. It happens without any seeming warning, and will happen at any time of day. Sometimes it will happen repeatedly, sometimes it won't happen for a long time. Both boxes have been repeatedly reset and rebooted with no improvement. During one tech call the tech had me relocate one of the standard boxes to the hi-def location to isolate that it wasn't a location (in-house cable) problem. I thought it curious since it was happening at 2 different locations but went through the drill anyway. The relocated standard worked for a few minutes, then went black for a second as the problem does. Plugging the high-def back in resolved the issue at that location. The tech said he would send 2 new standard boxes. The replacement boxes have not resolved the issue. Any suggestions?if it's doing that on two different boxes using both coax and s-video then I think that leaves a possibility of the coax. that would be a unusual symptom of a bad coax/splitter but try this.
Wait for it to start acting up - when it starts acting up, stay tuned to that station, and hit your menu > customer support > in home agent > network diagnostics and click ok to start.
check the video signal using that menu selection. after it's done running it will give you a general message like "you're video signals are not in the optimal range" after you see that, hit info and then look at the SNR DB it should give you a number.
32-36 is optimal, below that is questionable.
If it is below that then it's probably going to be a problem with the splitter at your house, and you would either replace it yourself, or call verizon to replace it. be sure to tell them the DB -
Hi I am building a website using iWeb's white template. I can't write HTML, so can't change the index, but would like to repeat it at the bottom of my pages. Does anyone know which typeface Apple used? Presumably it would be 'web friendly' for use as described above?
Arial
