suspended thread
HelloI have a wire hanging problem. Due to audio problems I had to create a separate thread for play/stop Quebec. The problem I have is that if I close the window as my audio thread run() hang the sons and the app is running in the back end.
Any way to hang the window close? I tried to use the closing bracket, but my hook is not called. Here is my code for the AudioThread. Here, I have the ShutdownHook code. I don't know that it is an old problem.
package utils;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import java.util.concurrent.SynchronousQueue;
import javafx.scene.media.AudioClip;

OK I solved the problem. The shutDownHook works. The problem was that I was getting an exception in my hook run(). The exception does not get sent to the screen, so I do not see.
Thank you

No debuggable thread tries to suspend execution
Hi all
I have a program that uses the WinMM library to sample the wave in a buffer for 0.015 s each s 0.030.
The program works well, but every now and then I get an error saying:
"A non debuggable thread tries to suspend execution at the address 7C90120E.
You want to stay the execution? »
You can choose to suspend or not, and in both cases the error will come again.
Sometimes it runs without problem for over 30 years, sometimes I get error every second, so at intervals very unregular.
I tried to make the sampling in a separate thread, but it doesn't make any difference (conceirning error)
I'm using LABWindows/CVI 9.0 for Windows XP Professional sp3 2002, using Windows SDK 7.1.
Anyone know what could be the problem?
Best regards, Dirk

Satellite Z930 - suspend the problem with connected USB hard drive
Hello
Owner of a newly acquired Satellite Z930-15 X, I have a few questions/problems:
1) suspends the work of RAM and good hibernation when there is no external hard drive connected. If there is one is connected, the laptop immediately returns back to suspend state. Is there a solution for this?
(2) is there a way to selectively disable Bluetooth? Currently, only toggle airplane mode is available (with Fn + F8 or Windows 8 charm bar). This activates / deactivates the Wi - Fi or Bluetooth I think.
(3) the portable computer is wobbly on reception. I put a bit of thin paper at the corner of a bottom (bottom left) so that it can be stabilized. Apparently, the problem is also mentioned in another thread. Is there a suggestion to fhix this problem?
Thank you.
1 / what HARD drive is connected to your laptop? When I use the external 2.5 HARD drive with my Satellite U940 I n t have problem.
2 / I ve tested it on my machine and I noticed the same thing. When WIFI is disabled software BT is off too. I didn t find a way how to separately control adapter WLAN and BT.
3 / I think that this issue needs to be clarified with Toshiba service. They must check and perhaps exchange rubbers inside.

9.2 mail application (Build 3112) hangs at the start of the application. Even in safe mode. Suspect some corrupt system and/or Mail Pref files / UI (?). Carried out the full charge of the OS X 10.11.3 (Build 15 d 21) and restoring from Time Machine backup. However, couldn't find any combination of deactivation of accounts and/or deletion of .mbox entries that could make it work.
I reloaded all the emails-sometimes suspended during reloading, then these offending .mbox directories has set aside for a later attempt. After rebuilding is finally completed successfully (more than one offending .mbox was withdrawn), the Mail App would just stroll. From dock app hangs after reloading resulted immediately reproducible.
Noticed the following in the problem report: sending sweet thread limit: 64 (too many threads to send blocked in synchronous operation)
Mail still works on my iPhone – so I know that IMAP accounts are OK...
Is there a way to restore my account of any user from a previous snapshot in Time Machine? (When I'm connected to the account that I want to restore, I get an error that the account cannot be changed or deleted because it is required by OS X. When I'm logged in on another admin account, I can't restore the structure of directories in the user library... Hmmm)
Suggestions?
Thank you.

Please, back up all data.
If you use iCloud drive, please open the iCloud pane in system preferences. There is a marked checkbox iCloud drive, and next to that, a button labeled Options. Click this button and in the sheet that drops, that uncheck Mail if it is checked.
Step 1
If mail crashes or freezes immediately on launch, try the steps on this page. Sometimes a damaged on a mail server message can be deleted by logging in to the server through its web page. If Mail doesn't always start, or if you are unable to take step 2 for any other reason, go to step 3.
Step 2
There are three types of e-mail account: POP, IMAP, and Exchange. You can determine the type of each account by opening the Mail preferences window, by selecting the tab accounts and then click on account information.
Export all the mailboxes of POP in the office folder.
If you have accounts IMAP or Exchange and you don't store sent, deleted, and junk messages on the server, export these mailboxes in the same way. You can determine if the messages are on the server by selecting the mailbox behaviors tab accounts.
Also export all the mailboxes in the category on my Mac.
You do not have to export the other mailboxes, because messages are stored on the servers.
Exit the Mail.
Step 3
In system preferences, open accounts (OS X 10.9 or later) Internet or Mail, Contacts and calendars (OS X 10.7 or 10.8). Take notes settings for each e-mail account (all types), and then delete the accounts.
Step 4
In the Finder, hold down the option key and select
Go ▹ library
in the menu bar. Move the following (some may not exist) in the folder that opens on the desktop:
Application Support/AddressBook/MailRecents-v4.abcdmr
Containers/com. Apple.corerecents.recentsd
Containers/com. Apple.mail
Containers/com.apple.MailServiceAgent
Containers/com.apple.share.Mail.compose
Mail
Note: you do not move the Mail application. You move a folder named "mail".
Step 5
Launch of Mail. It will behave as if you have been putting in place for the first time. Go through the process of installation with a single account, using the information from step 3. Test. If Mail works now, recreate the rest of accounting (if you have several) and other parameters.
Any writing paper custom that you created may be lost. Ask for instructions if you want to keep these data.
If there is no improvement, quit Mail and put back items that you moved to the desktop, replacing the more recent who can be created in their place. Stop here and post your results.
Step 6
If you followed step 2, importing mailboxes mailbox that you exported (see article of support related to step 2 for instructions.) Generally speaking, the process takes a few minutes, but this can take hours if you have gigantic mailboxes. In this case, you will be able to speed things up temporarily by adding your file to the list of personal information protection in the Spotlight preferences pane. Remove it when Mail has finished importing.
The mailboxes that you export should automatically synchronize with the server. Once again, if the mailboxes are very large, their download may take some time, and the network performance will be slower than usual during this period.
If you skipped step 2, find the mail on the desktop folder in a subfolder
V3/mailboxes (for OS X 10.11 or later version)
or
V2/mailboxes (for any previous version of Mac OS X)
Import mailboxes mailbox that it contains.
Test. If Mail still work, remove items that you moved to the desktop in step 4.
Reactivate the e-mail option in the settings to iCloud by car, if you have disabled it and retest. If you weren't already the iCloud drive with Mail, there is no need to enable it now, unless you want to.

Thread.ExternallySuspended method with asychronous vi
Hello
My sequence is launching a state machine in labview to type "launch vi" asynchronous queue stage teststand. The vi runs for the duration of my sequence, waiting and acting on the message queue, initiated by certain steps teststand that call an "enqueue" labview vi. I want teststand to pause while the work is done in vi, until the vi ends and waiting for another message from the queue. From what I understand reading page 3-7 in the teststand reference manual, use it "Testand - Set wire external suspeded.vi" in teststand palette should accomplish this. After reading this, I think, once there is a string in line waiting is received in the vi, set Thread.ExternallySuspended true and after work in vi, set it to false again to let the sequence to resume. But the first experimentation, behavior does not conform to this. The sequence continues anyway regardless of the true Thread.ExternallySuspended setting. Help file says 'allow TestStand to suspend the thread of execution parent while still running code in the code module'. The word "allow" implies that I need to do something on the side of teststand also, so he could take a break? If Yes, what?
Thank you
David J.
Doug,
I think you hit the nail on the head, and this looks like something that would work in reality. I have been to launch around something like this around in my head, but was not quite see where teststand would "listen" to the vi to do, but a message of the extra return of the vi worker queue is the perfect solution. It would take me just to add a "waiting" after "enqueue" in vi that sends the message to the queue, which is actually a vi attached to a type of step. While waiting to receive a message from the queue 'fact' return, teststand is actually suspended. It's great. This is a final head striker, would have thought this myself.
Thank you very much

The control law of read/write FPGA on the loop of the root / the UI thread?
Hi all
As the title suggests, the read/write control FPGA, https://zone.ni.com/reference/en-XX/help/371599H-01/lvfpgahost/readwrite_control/, is on the loop of the root / the UI thread?
Watch, https://zone.ni.com/reference/en-XX/help/371361J-01/lvconcepts/multitasking_in_labview/, this would indicate as that, but I would get a good response.
Kind regards
David
While I'm not 100% if it acts on the loop of the root / UI thread - calls to the FPGA (e.g. control of read/write operations FIFO) block permanently. I remember having a weird problem in the past where my FPGA operations have been suspended because I was expecting given FIFO elsewhere.
You should be able to test this easily enough - try to open a file dialog during playback of your FPGA. If playback crashes while the dialog is open, you have a loop of root problem.

Hello
Is there a CVI equivalent to LabVIEW rendevous for multithreading function? Or the OS primitives should be used to achieve this?
Thank you
I don't seem to remember a direct equivalent of CVI of LV rendezvous. You can use a variable of thread safe for this task: from scratch, each thread can increment the value of the variable by one and to expect that the variable has reached the desired value (i.e. the number of threads is suspended pending on the variable).

Hi Ronfirefox,
· You are able to start Windows without any problems?
If you are able to start Windows, then you can try to decrypt the volume and check if it works.
Follow the steps from the link: what is the difference between disabling BitLocker Drive encryption and decrypt the volume?: http://windows.microsoft.com/en-US/windows-vista/What-is-the-difference-between-disabling-BitLocker-Drive-Encryption-and-decrypting-the-volume
If you are still unable to disable the bitlocker, follow the steps proposed by Kevin in the link below and check if it works.

Press Service SDK Java low-level SE HowTo summary / suspend devices?
Thanks mdicesare messages in another forum PushServices Forum thread, it was easy for me to do the work of push service SDK:
using low level API
Java SE without Springsource support
I can
* push to devices
* request for status etc.
at the moment I am waiting for RIM add my url of notification of base develop all kinds of provision of Service Plus
3 things are open:
* sending subscription CV and SUSPENDS and subscriptions of the query
is this possible with low level API (common + pap components)?
BTW:
I develop a Solution Open Source (Eclipse Public License EPL)
to provide a dynamic server easy to use to push Services and TCP Socket connections
based on OSGI (Eclipse Equinox)
will post the info on blah forums if its not working fully
Then, you must only Eclipse and MySQL to run - no Springsource more or less
The Push server admin UI will be possible through smart BlackBerry or Vaadin phones like interface user Web or anything Eclipse Eclipse RCP and RAP
OK - solved questions
If you know how to do - it is easy ;-)
httpResponse = client.transmitGET( pushProperties.getSubscriptionResumeUrl()+"", "", // no contentType needed PUSH_APP_ID, //username your secret app-id PUSH_APP_PW, // password null); // no headers needed ... // same to suspend pushProperties.getSubscriptionSuspendUrl() ... // and to deregister pushProperties.getSubscriptionDeregistrationUrl() ... // some useful response returncodes: // rc-200 successfull // rc-10007 PIN not found // rc-10012 PIN already suspended now waiting for my url in notification of basic fixed by RIM - then I'm ready using low level of Java SE PushServiceSDK

shared object synchronized between threads/listeners
I don't know if I go about it the correct way. I'm hoping that someone could help with this situation. Here is basically what I want to do:
Have a FIFO queue object that contains the data to send to a web application that can be accessed synchronously between threads/listeners. Given that the coverage of the data can sometimes be slow or even non-existent, I need to wait for the cover, maybe using CoverageStatusListener that runs on a wire and will suspend/resume the thread on state change. All this must happen without the need of Auditors threads to wait.
For example:
data coverage is non-existent
ListenerA needs to send data, it places in the queue
data coverage is restored. Data queue
ThreadB needs to send the data until the transmission is completed. We need the data in queue
transmission of complete, passed down from queue data is removed from the queue
During all this time, I need ThreadB data exist also in the queue object and not be lost when the data is complete and is removed from the queue. I need ThreadB to continue treatment and do not wait until the transmission is completed. I played a bit with display of threads that are cycled every five minutes or so if they could not pass successfully, but that logic is not feasible. Say you are out of the coverage of the data for an hour or two, but you end up needing to pass 50 items. You have 50 son sitting there waiting to pass. Or a listener for each point that everyone is trying to send at the same time. What happens if the device dies or is reset? I looked at RuntimeStore, but that does not record the data and I don't know what happens when 2 wires need to add data to the queue at the same time. PersistentStore will not be able to hold the data if/when it becomes too large.
Here it is the pseudo-code. I know that some things will probably not work. Just trying to get down the basic logic.
public class TestFoo extends Application { public static void main(String[] args) { TestFoo foo = new TestFoo(); foo.enterEventDispatcher(); } public TestFoo() { CoverageInfo.addListener(new CoverageListener()); ThreadA threadA = new ThreadA(); threadA.start(); ThreadB threadB = new ThreadB(); threadB.start(); } public class ThreadA extends Thread { public ThreadA() { } public void run() { while (true) { //do stuff if (/*something */true ) { } } } } }public class HTTPThread extends Thread { private boolean suspended; private FIFOQueue queue; public HTTPThread() { setSuspended(false); /* * get queue from filesystem??? * or create new queue if not there??? * load into RuntimeStore??? */ } public void run() { while (true) { if (isSuspended()) { try { wait(); } catch (InterruptedException e) { } } //fetch queue from RuntimeStore??? if (queue.isEmpty()) { try { wait(); //can notify us when an object is added to the queue??? } catch (InterruptedException e) { } } if (hasDataCoverage()) { Object obj = queue.getHead(); boolean successful = false; if (obj instanceof MyObject1) { MyObject1 myObject1 = (MyObject1)obj; //send data based on MyObject1 structure; //set successful } else if (obj instanceof MyObject2) { MyObject2 myObject1 = (MyObject2)obj; //send data based on MyObject2 structure; //set successful } else { //not a valid object of mine for some reason } if (successful) { //get queue again from RuntimeStore??? queue.removeHead(); //return queue back to RuntimeStore??? } } } } public synchronized void setSuspended(boolean suspended) { this.suspended = suspended; } public synchronized boolean isSuspended() { return this.suspended; } }public class CoverageListener implements CoverageStatusListener { //Only location this will be started so only one instance exists private HTTPThread httpThread; public void coverageStatusChanged(int newCoverage) { if (!httpThread.isAlive()) { httpThread = new HTTPThread(); httpThread.start(); } if (newCoverage != CoverageInfo.COVERAGE_NONE) { if (httpThread.isSuspended()) httpThread.setSuspended(false); } else { httpThread.setSuspended(true); } httpThread.notify(); } }public class ThreadA extends Thread { public ThreadA() { } public void run() { while (true) { //do stuff if (/*something */true ) { //Somehow put data into the queue } } } }I think that there are a number of; habits that will help you design it - the producer/consumer and observer patterns come to mind. I'm not a design guru so will not pretend even to help you work through this. But all I can say is that models provide generally well thought out structures for the problems that. I encourage you to read about them. You might find these useful references:
http://www.javacamp.org/designPattern/
http://zone.NI.com/DevZone/CDA/tut/p/ID/3023
In general I'm not comfortable with your overall solution. I would look at something like that
(a) offer a 'service' to your users that collects the data to send. There is no need to be a wire, it is just a method that they call and pass in the data. These data are persisted. This method 'Add' is owned by the transmission process and is the only visible part of the outside of the treatment. This treatment should also begin sending wire (see b) if it is not executed.
(b) have a thread that attempts to send the data. You can launch this thread on changes in coverage if you want, but make sure that you can have a single run. This thread should check coverage before attempting to send anything, and just end if there is no point of trying.
(c) your submission Thread will get in situations where she send and does not receive a response from there is another error. In this case I recommend the blocking of the Thread for a time and then try to send again.
(d), I said in (a) that the add-in has been the only visible part of the outside of this treatment. However you're better instrument your process so that users can find out if your thread is running, how much he sent, if the last transmission worked or not of data and so on.
Treatment based on a vector of data to send. Synchronize on this vector before changing. In the "add step (a), add an element to the vector." In processing step (b) delete the first item when you have treated.
There is a problem with this design in that there may be overlap if the sending thread terminate because it has nothing to do and add treatment add something and does not start the Thread because it is actually running. You must code carefully around that.
I hope this helps.

Need help on concepts of threads
Hello! I need your help on some concepts related to threading, implemented in the J2ME.
I have a file which is a singleton, and executes the actions in the order in which they are stacked. Everything works well, but sometimes, I have to do an operation on the queue. Set some variables with a value of internal audit. It is here that I found the problem. Even if my class is a Singleton (I checked, it's really a singleton), I have 2 different instances of my class. Who is "managed" by a background thread, the other by the interaction of the user interface.
How to synchronize these 2 objects in one? I absolutely need my background thread to use the same queue like everyone else.
Here is a version stripped of my Singleton:
package ca.victrix.sp.synchronizer.action; /** * Class used as a queue of different work processes * @author slevert * */ public class WorkQueue { private final PoolWorker thread; private final LinkedList queue; private static boolean networkActivated; private static WorkQueue workQueue; /** * Gets the one and only instance of the queue * @return WorkQueue */ public static WorkQueue getInstance() { if (workQueue == null){ synchronized(WorkQueue.class) { WorkQueue inst = workQueue; if (inst == null) { synchronized(WorkQueue.class) { workQueue = new WorkQueue(); workQueue.setNetworkStatus(true); } } } } return workQueue; } /** * Sets the network status * @param activated */ private void setNetworkStatus(boolean activated) { networkActivated = activated; } /** * Gets the network status * @return boolean */ private boolean getNetworkStatus() { return networkActivated; } /** * Private constructor */ private WorkQueue() { queue = new LinkedList(); thread = new PoolWorker(); thread.start(); } /** * Executes the actions by adding them to the linked list and by notifying the queue of the change * @param runnable */ public void execute(Runnable runnable) { synchronized(queue) { if(!getNetworkStatus() && runnable instanceof WorkRecoverable) queue.addLast(runnable); if(getNetworkStatus()) queue.addLast(runnable); if(getNetworkStatus()) queue.notify(); } } /** * Activates the queue */ public void activate() { this.setNetworkStatus(true); synchronized (queue) { queue.notify(); } } /** * Suspends the queue */ public void suspend() { this.setNetworkStatus(false); } /** * Check if the network is activated * @return boolean */ public boolean isNetworkActivated() { return networkActivated; } /** * Private class used to pool the threads * @author slevert * */ private class PoolWorker extends Thread { /** * Runs the action */ public void run() { Runnable runnable; while (true) { synchronized(queue) { while (queue.isEmpty() || BlackBerryCore.getNetworkCoverage() == CoverageInfo.COVERAGE_NONE) { try { queue.wait(); } catch (InterruptedException ignored) { } } runnable = (Runnable) queue.removeFirst(); } try { runnable.run(); } catch (RuntimeException e) { execute(runnable); } } } } }Thanks in advance!
Think that you have fallen into one of the traps BlackBerry.
A static is NOT a singleton.
You will get different instances of static variables for various startups, so your GUI and your automatic boot process will have different static.
If you are not persistent data, the best place for this is RuntimeStore. Read the following Article.

I have a thread main game loop, I want to run constantly in the background:
import net.rim.device.api.ui.UiApplication; public class NewGame extends UiApplication { /* gameState amd newGameState: * 1 - Main Menu * 2 - Options * 3 - Help * 4 - About * 5 - Exit * 10 - Play Game */ public int gameState = 0, newGameState = 1; private boolean stillAlive = true; public MainGameLoop mainGameLoop; MainMenu mainMenu = new MainMenu(this); public static void main(String[] args){ NewGame newGame = new NewGame(); newGame.enterEventDispatcher(); } public NewGame(){ mainGameLoop = new MainGameLoop(); } private class MainGameLoop extends Thread { MainGameLoop() { start(); } public void run() { while (stillAlive) { if (newGameState != gameState) { switch (newGameState) { case 1: pushScreen(mainMenu); gameState = newGameState; Thread.yield(); break; } } } //Exit Game System.exit(0); } } }When he pushes the main menu, I get an error as soon as starts to thread the main menu animation. If I start the main menu thread without running the thread of the main loop of the game, it works perfectly. Then, of course, I am unable to run these 2 threads at the same time. I tried to give the first thread as soon as the main menu thread starts, but it does not help.
I have also tried to main menu of sleep for 500ms ever iteration, even thought it is supposed to be suspended, but that didn't work either.
Here is the thread from the main menu. I removed all my personal code not covered do not threads:
import net.rim.device.api.system.Bitmap; import net.rim.device.api.ui.Graphics; import net.rim.device.api.ui.container.FullScreen; public class MainMenu extends FullScreen { NewGame newGame; public MainMenuLoop mainMenuLoop; public boolean stillAlive = true; //Menu Item Chosen (0-Play Game, 1-Options, 2-Help, 3-About, 4-Exit) private byte menuItem = 0; MainMenu(NewGame m) { super(FullScreen.DEFAULT_MENU | FullScreen.DEFAULT_CLOSE); newGame = m; //Load images mainMenuLoop = new MainMenuLoop(); } private class MainMenuLoop extends Thread { MainMenuLoop() { start(); } public void run() { while (stillAlive) { //Menu animations code here invalidate(); } } } protected void paint(Graphics g) { //Drawing routine here } protected boolean navigationMovement(int dx, int dy, int status, int time) { //Check for Input from Trackball //Movement code here return true; } protected boolean navigationClick(int status, int time) { //Check for Clicks from Trackball return true; } }So, once more, if I call the main menu directly without using the main loop of the game, I have all the problems. If I start the main loop of the game and call the main menu of him, I get an error when the thread starts. Here is the error:
JVM error 104
Eception:
IllegalStateException
Thank you in advance!
Keith
As said previously, you don't need to run a thread explicitly to the "main menu" thread because stuff specific to the Blackberry user interface is already running within a thread, known as the "event thread". There are restrictions on other non-event threads trying to do some UI on the event from another thread thread (unless you synchronize on the lock event variable). When you gave birth to your thread and try to do things on the thread of the event, you will receive this exception.

Suspend problems in mode: don't wake up from sleep
Hello!
I just installed Windows 7 to my HTPC. Media Center is great!
But I have a problem. When I put my computer to sleep he wakes more. In fact it isn't even sleep properly. It seems that everything is turned off but the graphics card. There is no picture but the fan is screaming. He is unresponsive to the buttons of the mouse or the keyboard. Even the computer power button does not wake up or restart. All I can do is press the power button for a while to make the computer stop. I have a Logitech wireless set with PS/2 Sockets. I rechecked all power management settings already. In the BIOS are enabled all supports the ACPI and wake up PS/2 support. I can't understand how to fix it!For this afternoon, I tested Ubuntu 9.10 and had similar problems there. In Windows XP sleep works very well, however.
My transactional includes:
AMD Athlon 3200 +.
Asus A8V - XE motherboard
Kingston 2GB DDR
GF 8600 GT 256 MB
Seagate Barracuda SATA 250 GB (for BONES)
WD Caviar 750 GB SATA (for data)Now, I found that it is the USB controller who refuses to go to sleep. There is a hidden feature in Windows 7 that you can use to find problems in the energy saving modes.
In the command prompt, give a command:powercfg-energyand it will generate a report on the problems in your system. The report can be found at /Windows/System32/energy-report.htmlMy report has revealed that there are two or three USB host that cannot be suspended correctly. After disabled USB support in the BIOS of the system had no problem in sleep. Of course I can't use USB devices more.Is there some kind of fix or tweak for Windows 7 USB drivers? Windows shows it has the latest drivers if I try to update.My motherboard is Asus A8V - XE, and there Via K8T890 chipset.EDIT:I found an answer on this thread: http://social.answers.microsoft.com/Forums/en-US/w7performance/thread/8059106b-21e2-4d17-bf2f-513a5b5d1d0b/Apparently it wasn't a USB socket that wasn't able to sleep but a USB device. I had a USB Memory Stick and the infrared receiver plugged and after removing their sleep works very well. -

The host restarting does not solve the problem, but I don't want to restart every time when I take the guest.
I tried the Tech Preview version and got the same result
