Problem with starting more than one SwingWorker

Hello
I wonder if anyone could tell me if there are known problems with starting more than one SwingWorker thread at once?
In response to an action the user performs, I need to obtain several lists of things from the server. This includes a couple of server-calls, and I want to do the server calls in a thread outside the awt-event thread. So I start a couple of SwingWorker-threads. This works fine sometimes, but not always. Sometimes code in some of the SwingWorkers finished method does not update the ui. I can see that the correct calls are made, but the ui is still not updated correctly. The problem seems to be related to the sequence of when the different thread are finished. For instance, if the sequence is like this:
SwingWorker1.construct
SwingWorker2.construct
SwingWorker1.finished
SwingWorker2.finished
Things go fine, but if the sequence is:
SwingWorker1.construct
SwingWorker1.finished
SwingWorker2.construct
SwingWorker2.finished
the ui-updates in SwingWorker1.finished is not done correctly.
Can anyone help me with this?

This is the point:
In one SwingWorker thread you have 1 construct method, and 1 finish method - which are both invoked once.
Therefore you only have one opportunity to update the gui in that thread. This forces you to use many threads if you want regular updates, which I try to avoid.
Therefore, the solution!
Have a loop in the construct method that executes the algorithm accordingly, updating the gui accordingly at regular times, maintaining just the 1 thread - becomes easier and nicer for the programmer and the JVM.
The finish method in this case is to update the gui when all iterations are finished.
There is nothing wrong with this. Just because you have a finish method that is called in the event-dispatching thread doesn't mean that all your update code must be in there.
What you MUST ensure is that ALL your update code is executed in the event-dispatching thread, that is the most important thing. After all, SwingWorker is just a helper class, not the gospel template of how to update a gui.

Problem with printing more than one page (ghostscript broken?)

Hello,
since one of the last package updates I have problems with printing more than one page. The print problems occurs as well with pdf files as well with printing websites. I use an actual KDE system with commercial turboprint printer driver. The first page always prints fine, but all consecutive pages are corrupted. As from a similar problem some months ago, I assume a broken ghostscript package. I tried to downgrade ghostscript to check that, but I get depency problems:

Anyone else having printing problems or a solution for my problem?
Thanks, Dieter

This may not be related but I had a problem printing a pdf today whereby the second page got corrupted. The same pdf had printed fine several months ago. I realised that (long story) for some reason I had switched drivers (HP printer) from hpijs to hpcups. I installed the printer again as a "new" printer using the hpijs driver and it printed properly this time.
So it may be that the bug causes issues with some drivers. You could try an alternative driver for the printer as temporary workaround?

Problem with Assigning more than one value to GROUP dynamically

Hi,
I have a problem with assigning more than one value to GROUP varible dynamically.
I am able to assign only one value dynamically through Initialization block
I have even tried with the ROW-WISE initialization blocks..
using this query..
SELECT 'GROUP', G.GROUP_NAME
FROM GROUP_MAP G
WHERE G.USER_NAME = ':USER'
if GROUP_1, GROUP_2 are two groups to be associated,
through this, i'm getting " GROUP_1;GROUP_2 " into GROUP variable ( seen from Narative view )
And the properties and securities of this Groups are not inherited.
Please let me know if there is any other way to Populate the GROUP variable dynamically with more than one value.
Thank you.,

Hi,
i finally got in this way..
i had created a function which takes USER_NAME as input and returns a string that contains the GROUP names with semicolon delimeted..
Though it is same as that of ROW-WISE initialization,
the properties of those groups are also being inherited..
Now, i can assign more than one groups and its properties to a user dynamically.

Problem with passing more than one parameter to a function

Dear Experts,
I have a strange problem while trying to pass parameters to a function in Csharp :
On my database I have a function like
function fooo (parameter1 varchar2, parameter2 varchar2) returns number {
I want to write a csharp function which can execute those functions with varying numbers and types of parameters and returning always a number (see below).
My problem is, that I always pass only one parameter, the second parameter seems not to reach the database-function although I can see
all parameters within the OracleCommand structure (dbcommand) in the debugger.
Can you give me a hint why my function does not work ?
Best regards,
Desperately Daniel
This is my function :
public override int insertDataSetwithReturn(String ProcCall, ArrayList Parameters, ArrayList ParameterTypes, ArrayList ParameterNames)
int ReturnValue = 0;
try {
//Check for compliance of Arraylength
if (!(Parameters.Count == ParameterTypes.Count)) {
//falsche Eingabe !! TODO !
DBConnection myDBConnection = new DBConnectionORA();
DBPOOL.getConnection(out myDBConnection);
OracleConnection myOracleConnection;
myDBConnection.getConnectionout(out myOracleConnection);
OracleCommand dbCommand = new OracleCommand(ProcCall, myOracleConnection);
dbCommand.CommandType = CommandType.StoredProcedure;
//Nun die Parameter aus der Parameterliste füllen.
for (int ParameterCounter = 0; ParameterCounter < Parameters.Count; ParameterCounter++)
OracleParameter myParameter = new OracleParameter();
myParameter.ParameterName = (String) ParameterNames[ParameterCounter];
myParameter.OracleDbType = convertdotNetVariableTypesToDBVariableTypes((String) ParameterTypes[ParameterCounter]);
myParameter.Direction = ParameterDirection.Input;
myParameter.Value = Parameters[ParameterCounter];
dbCommand.Parameters.Add(myParameter);
OracleParameter returnParameter = new OracleParameter();
returnParameter.ParameterName = "ref_ret";
returnParameter.OracleDbType = OracleDbType.Int16;
returnParameter.Direction = ParameterDirection.ReturnValue;
dbCommand.Parameters.Add(returnParameter);
dbCommand.ExecuteNonQuery();
catch (Exception e)
string MessageStr;
MessageStr = "Error insertDataSet (DBConnection_ORA insertDataSet). " +
Environment.NewLine +
e.Message + "." +
Environment.NewLine;
MessageBox.Show(MessageStr, "Error in getArrayListfromProcedureNIP",
MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
} //catch
return ReturnValue;

Hi,
Can you give exactly the error generated by the application?
You can try to reverse the invoking of the parameters. That means, try to invoke the returnValue parameter first and then the others ( IN Parameters ) in the same order that you declared them in your stored procedure.
in PLSQL you have,
Create or replace function ( parm1 IN varchar2, parm2 IN varchar2, parm3 OUT varchar2)
In your application, you must write first:
bla bla bla parm3.direction=parm3.returnvalue
and then
bla bla bla parm1.direction= parm1.input
bla bla bla parm2.direction= parm2.input
Hope this helps you

May I start more than one interface at boot using network profiles ?

Hi everybody,
I installed ArchLinux on my laptop and I was playing with network profiles to obtain different configurations of the ethernet and wireless interfaces for home, office etc. Everything works fine using "!" in from of each configuration name in /etc/rc.conf and I found useful the menu option.
As far as I understood each configuration file in /etc/network-profiles/ correspond to one interface only, therefore this utility does not allow me to start more than one interface at boot time. Am I right?
In this case it exist already a script to choose between different configuration for two interfaces?
Thanks in advance

Welcome to the Apple Community da dad.
Yes you can connect multiple Apple TV's by ethernet.
What do you mean by outside.

Can we start more than one user created database at the same time

Hi.,
Can we start/work more than one user created database at the same time ??
--Shyam

Hi Shyam,
I really dont understand what you have asked?
If your question is can we start more than one database at the same time then the answer to that is yes but provided to have enough resources on your server to support running of two or more different databases on the same machine.

How to start more than one program automatically? [RT]

Normally you can build an application and let it start automatically on the PXI system. You have to put the file into c:\ni-rt\startup\
But how to start more than one application in a pre-defined sequence? Depending on the situation there are several programs to be started that run simultaneously.
I searched for help in the Development Library and the Forums but I didn't find an answer.
Thank you very much for your helpin advance! Have a nice day!
Christoph

Hi Christoph,
You can use VI Server on the real-time target to launch other VIs dynamically. Your startup executable could be a simple application that uses VI Server to start other VIs that run in parallel in a pre-defined sequence.
Here's an example that does something similiar.
Note that when you build the VI into an application, you must include all the VIs that are called by VI Server as dynamic VIs in the application builder.

Problem with opening more then one file in Adobe Acrobat X Pro - nvd3dum.dll

Hello,
I have Adobe Arobat X Pro version: 10.0.1.434. Everything works great up to now. Last time I done upgrade my system to windows 7 64bit with SP1. When I open pdf file in adobe acrobat everything works great, but when I open second file, I receive this problem that Adobe acrobat stopped working and I receive this error : nvd3dum.dll.

Hello Dave
the Problem affects all Uniplot 3d Files. I start with an Excel or .txt file with 3 columns and uniplot creates an engine diagram similar to this one: http://www.uniplot.de/documents/de/_images/Uni_BSP7-2.png
Uniplot can Export this as a .u3d but it can not be opened with Adobe. Then I tried to open the .txt.file with MeshLab. I can see the correct Points (which Uniplot uses to create the engine diagram) but of course they are not connected. If i Export those Points in MeshLab as a .u3d file, Adobe can not work with it.
I do not know how to deal with this Problem. Do you have any suggestions?
Thanks in advance for your help

Currency Translation for Key Figures with Value More Than One Currency

Hi...
I have query which display key figure GL Account Balance. The currency that used for this key figure is USD and IDR. How we want display value based on selection screen? So if we input currency USD, all value that use currency IDR translated to USD and all value that use currency USD not changed. Otherwise if we input IDR, all value that use currency USD translated to IDR and all value that use currency IDR not changed.
How we do this in query designer? Thank you.
I have use currency translation :
1. (Right Click Key Figures >> Properties >> Currency Conversion Key)
2. Target Currency Using Variables Entry
but seems the result is not correct. Can anyone help me ?
Regards,
Satria

Hi all,
Thanks for your help, but still I have problem. I have create one currency conversion type, ZXXX. This currency conversion type is using exchange rate type = "M",source curr from Data Rec, sel of targ currency with translation,
and fixed time ref = "Current Date".
Problem:
1. With this setting, i create currency translation in BEx, but the result is not same, it's like the exchange rate not using the same setting with data in ECC (I compare data with transaction fs10N). Is my setting for exchange rate not correct?
2. When I try to display GL Account Balance --> Calculated Key Figure (Total Debet - Total Credit) for period 0, the translation not working. Example if the value is IDR 1234 then the value in USD still USD 1234. Why this happen?
Thank you

Problem is having more than one FrameAccess object running in multithreads

Hi all,
I have a problem with my system which uses JMF for frame capture for frame processing. The system flow is like this -
I use a FrameAccess.java (modified from the one provided by Sun) to grab frames. I use 5 different threads to create an associated FrameAccess object (i.e. one thread owns its own FrameAccess object ). And then they will do their own processing (all of them are implementing motion estimation thing using buffered image from the frame).
The problem is , when I examine the frames captured from the 5 threads, something irregular happened.
For example, the thread A (capturing video A) may return frames captured from video C. such scenairo happened without signs and patterns. Sometimes a thread even return something like half frame from video C and half from video B.
I would like to know if there is any way to check if it is the problem of JMF (can't synchronize frame capturing), or it's the problem of FrameAccess object (but they are in five independent threads ><")
Thank you very much...

It is a problem with how you are handling threads.
Thread one calls frame access, then thread 2 calls frame access, and it is possible that thread one will only get half a frame.
You will probably have success by syncronizing your calls to frameaccess(lock), and then unlock when that thread has a complete frame.
This way only one thread will access frame access, at any one time.
I have had this exact problem, when trying to capture every single frame, save it to jpeg.
Half the problem was writing to disk before the frame was complete, thus showing have a picture.

NIO - Selector problem - when using more than one in same application

Hi,
I'm developing a multiplayer-server, which shall be able to handle at least 2000 concurrent clients. To avoid the use of 4000 threads for 2000 clients (a thread for each stream), I would like to use NIO.
Problem:
The server has of course a ServerSocketChannel registered with a Selector, and when clients connects, the SocketChannel's is received. IF these channels is registered (OP_READ) with the same Selector-instance as the ServerSocketChannel, there is no problem and the Selector recognizes when a registered SocketChannel is ready for OP_READ - BUT when the received SocketChannels is registered with another Selector-instance than the one the ServerSocketChannel is registered with, the Selector NEVER recognizes, when a SocketChannel is ready for OP_READ - why not and how do I solve the problem? Only one thread can service the same Selector-instance, and when both receiving many connections and read/write, this could easily be a bottleneck
Following is the used code; 2 classes: ClientListener (has a ServerSocketChannel registered with a Selector) and ClientHandler (has another Selector where the SocketChannels is registered and a thread-pool that services all the SocketChannels, when they are ready for read/write):
public class ClientListener {

is triggered. If this is the first key you're adding
then select has nothing that will wake it up, ever.
The result is, obviously, a deadlock.
The solution is to have a queue of pending connections.
You put your new connection in that queue. Then you
wake up the selector and let that thread go through
the queue, registering connections."

Need help with haivng more than one Ipod.....

Ok, I have gone through these posts and am still having trouble. I already had my daughters shuffle on our computer from last year. My husband and I both got Ipods for Christmas this year. I registered mine under a different email and created a new account for mine so it would be different than my daughters. As soon as I plug mine into the computer, it loads ALL of her songs onto mine. I had to restore my Ipod to delete all the songs but if I plug it in again, it will start to load all of her songs onto mine again. What am I doing wrong? I purchased one song to test it and it adds it to her list. I have seen the posts on here about making the seperate playlists but I have no clue what I am doing. All I know is that as soon as I plug mine back in, I am getting all her songs. What steps do I need to take to fix this. Please help!! With 3 Ipods, What is the best way for me to set this up. Anyone that can help please feel free to also email me directly, I am deseperate. Thanks!

I have just posted a similiar question - my son got an iPod for Christmas and I can't make a seperate account either. Here is a link that someone sent me...maybe it will help you.
The only thing that will help me is someone else coming over and doing this for me because I'm going out of my mind trying to fix it! Good luck.

URGENT! Help with creating more than one linked button

Hi!
Could someone help a newbie with trying to figure out this.
I work in Flash CS3, AS3.
I've created a button that links to another webpage by using this code (the code is added to a separate layer):
import flash.events.MouseEvent;
steud.addEventListener(MouseEvent.CLICK, onMouseClick);
function onMouseClick(e:MouseEvent):void
var request:URLRequest = new URLRequest("http://www.xx.html");
navigateToURL(request, "_blank");
It works just fine, but the problem is that I want to add more buttons (and links) to it, and thats where I get stuck. When I try just adding a new layer and adding the code there, everything stops working. I've also tried copy/pasting the code beneath the first one, with no results.
Does anyone know?

I will try
I've modified this tutorial http://www.tutcity.com/view/create-a-sliding-content-with-back-and-forward-navigation.2394 7.html and the intent is to make a sliding menue that contains images of plants that link to the url of the plant. I've got buttons (with a mouse over effect that shows the name of the plant), and in AS2 I could use GetURL to link an invisible button to the URL, but to create the sliding effect, I had to use AS3. I've understood that GetURL doesn't work in AS3.
In scene 1 I have three layers; content, arrows and actions.
The actionscript looks like this:
// File downloaded from www.riacodes.com
import com.greensock.*;
var arrayX :Array = [0,-800,-1600,-2400,-3200,-4000,-4800];
var currentIndex : Number = 0;
left_mc.addEventListener(MouseEvent.CLICK,navigate);
right_mc.addEventListener(MouseEvent.CLICK,navigate);
left_mc.buttonMode = true;
right_mc.buttonMode = true;
checkArrows();
function navigate(e:MouseEvent):void{
if(e.currentTarget == left_mc) currentIndex --;
else currentIndex ++;
checkArrows();
TweenLite.to(content_mc,.5 ,{x:arrayX[currentIndex]});
function checkArrows():void{
if(currentIndex == 0) left_mc.visible = false;
else if (currentIndex == arrayX.length - 1) right_mc.visible = false;
else{
left_mc.visible = true;
right_mc.visible= true;
On the content layer I have the backgroundimages that slides as a movieclip.
If I doubleclick on the movieclip I have two layers, one with the bakground images and the invisible buttons, and one layer where I've put the script:
import flash.events.MouseEvent;
JC.addEventListener(MouseEvent.CLICK, onMouseClick);
function onMouseClick(e:MouseEvent):void
var request:URLRequest = new URLRequest("http://www.blomsterbolaget.se/vaxtsidor/Dracaena_fragrans_JC.html");
navigateToURL(request, "_blank");
JC is the instance name of one of my buttons. So far everything works, but I want to add linking to another button, and I'm not sure how to do this correctly. When I've created the invisible buttons, I've drawn a square, converted it to a button, named it, and named the instance name. Changed the Alpha to 0. I've also added an On mouse over effect, but I don't think that has anything to do with this.
Hope you can help med!

Can't describe problem...more than one!

Ok these are the problems i seem to be having....i haven't had chance to try on another comp yet, so if someone can help me with it without doing that, it would be helpful!
1. i plugged it in the other day and it said (or rather had) a different battery symbol, ok read on the net that the battery is just dead so recharge it. Left it for a bit...and then it came up with
2. a little envelope with an exclamation (all of this in black and white)
3. read about that, you need an update. so i downloaded the thing and when i went to update it, it said it was doing it so i left it, then the comp crashed and so i had to reset the comp and
4. now when i plug it in, it's not recognised by itunes, all my songs have gone (from the ipod, not itunes) and it just says do not disconnect and when i try and safely remove it it doesn't work.....
5. i tried to restore it (there's no songs on it anyway, so why do i care) but the updater/restorer thing says that i need to plug an ipod in....THERE IS ONE PLUGGED IN YOU IDIOT is what i scream at the comp......obviously they don't understand, they're stupid.
So that's where i am at the moment, really annoyed! please help me!

Before you try some of the suggestions bear in mind that your iPod is still under warranty.
