• HDR5010KB-digital recorder - signal does not always come through the use of HDMI

  Hello

  I bought the product above in October. Since then, I have had intermittent problems. When switching on the channel AV on my TV (a Panasonic TX-P42S20B) signal is not always crossed when you use the HDMI channel (I also connected via a SCART, and who works so always seems to be a problem HDMI.) It is particularly obvious when the recorder has been used for a while (be it for recording or playback.) It is not overheating (or if this is the case, not to the degree I get a warning message) and turn off the power to the electric network seems to correct the problem, but it's a pain.

  I tried to change the hdmi cable, as well as to try different channels AV on my TV and it did not help. Is this a common problem or make me a defective unit?

  Any suggestion would be appreciated

  Have you noticed the same problem using other devices connected to your TV (using the same cable)?

• VI not emitting the Signal DAQ

  I'm working on a project that requires two different waveforms to two separate channels. It also includes a trigger for a computer that has a camera connected to it. I received a VI that someone had already used for a similar project and had to learn LabVIEW 'language' for the first time. Unfortunately it does not appear to be out of any signal through data acquisition channels. I've combed on VI is not looking for something to strangely wrong without result; everything looks like it should work, but it simply does not work. I used a simple signal generator provided with LabVIEW to generate a sinusoidal signal, and he did show my two-channel oscilloscope. I also tested all the hardware to ensure that the VI was at fault. Is could someone please help me understand this problem? It would be much appreciated.

• Programmatically trigger a structure of the event with the value (signaling) is not responding

  Hey, in my attached program I check if the two steps of translation are in a specific position. If Yes, I want my code to execute a sequence of movements. If this isn't the case, I'm asking the user if he wants contributed from this position anyway. It has three options: Yes, go to load (the specific position) and cancel. If he hits Yes, I am using a property of signal value which should update the controls Boolean true, allowing the sequence. Cancellation and work "to load" perfectly fine, but 'Yes' does not work. I think I need a structure of the event to ahndle the value of the Boolean control 'x' change event, however, the addition of this structure of the event for some reason any even do not allow me to click on the Start button of the procedure.
  Thanks for any help in advance.
  Doug

  Really, you should look into using a State Machine.  You should have really not what happens inside a structure of the event.

  In addition, I would like to use a shift register to store this value instead of a front panel control.

• Error to the element of the queue with simulated signal, but not with the DAQ hardware

  Hello.  I get an error code 1 when I run my VI in simulation mode, which is only 3 simulate subvis signal at different frequencies.  The block diagram shows jpg file and the probe is after I stop the VI.  Note that there is an invalid refnum.  I don't know why that is.  I am also including the watch of the probe after a few iterations, there is no error on the probe 64 until I stop the VI, and also noted that there have been no queue items.  This of course means that I don't get to remove the data in loop 2.  An interesting note is that the system works fine when I run the program in data acquisition mode, which is the other case behind the 'simulate signals. "  In this case, the only thing is the DAQ assistant and dynamic data of the tunnel cable.  Everyone can't see what I could do wrong?  Thank you.

  Thanks for looking at my post.  I thought about it about five minutes ago.  I didn't have a timeout on the handeler event, so it was not double check for new items in the queue.  I don't know yet why the probe shows showes that items have not put in the queue because they certainly were.  Maybe "queue items 0" means that there are no items saved in the queue. ?

  Your concern is interesting and deserves a check...  I just ran it without registration, and it seems that the release of the case (the default) record structure is just an empty DDT, a placeholder, I guess.

• Why is the trigger of the DAQ signal works not as I expect?

  Using the DAQ Assistant, I have received a signal at a rate of 100 k Hz and number of samples of 75 k. I would like a light every time that the amplitude of the signal falls below 1. As you can see from my attached graph, the amplitude becomes less than 1. However, the light does not turn. Any suggestions on what I'm doing wrong or misunderstanding, that I might have? This is my first project with the DAQ Assistant, then perhaps there is something simple that I'm missing.

  Hello

  The problem in your VI is that you gain 75 k samples, but you check if the second sample is less than 1V.

  This is because the Index Array node, it will give you only a single element of the array, which means a single sample.

  You should take just a sample at a time, or send the table going into a tunnel of indexing. But that could slow things down when you have so many samples.

• DAQmx generated signal is not continuous

  Hello

  I have a question affecting the DAQmx functions in combination with LabVIEW RT. I use DAQmx write on a target RT is a feature to send an analog signal to the AO0. And what happens is that I only get short impulses whenever the data acquisition function is enabled. Failure is not recognizable when you work with a duration of 1 ms, but when switching to a slower rate, it is clearly visible.

  I am using the following options:

  Sample (on request)

  Terminal config: CSR

  Min 0 V

  V max 4

  Do I have to use the function of synchronization DAQmx or something like that?

  When I use the standard screw RT, the RT Assistant product I can only use the write function DAQmx that it works everything just... tested with a flat structure of sequence with 4 frames, 2 different output signals and 2 for the waiting time. So I think it's a failure of programming...

  I have no idea what my fault is, any suggestions?

  Thank you

  You should definitely use task start and clear job instead of a single write functions.  Take a look at a few examples DAQmx in LV if you don't know what I mean.

  My guess is that, given that you use a single entry and not to perpetuate the task, the task is closed after the writing of single point.  When the task is closed, LV is automatic setting the output to zero.

• Radio signal does not, but the switch is on.

  I use a Toshiba Qosmio x 305-windows vista 64-bit. My wireless router has been working well for a few months, since I got it. My radio signal light is not the same if my switch is set to position it. I'm in the Pro Intel/Wireless Tools and run the Diagnostics and it says that the radio signal failed. I tried to disable the network card and reactivating it, but that does not work either. Don't know what to do next. Please help, thanks

  Hello

  Maybe this can help.

  Check the Device Manager for the wireless card valid entry.

  http://www.ezlan.NET/Win7/net_dm.jpg

  If there is no valid entry, remove any entry from fake and re - install the drivers for the wireless card.

  Check network connections to make sure that you have a network icon/entry wireless connection, and that the properties of the icon (right-click on the icon) are correctly configured with the TCP/IPv4 protocol in the properties of network connections.

  http://www.ezlan.NET/Win7/net_connection_tcp.jpg

  Make sure that if there is Wireless Utility a utility vendor is not running with the native Windows wireless utility.

  Make sure you firewall No. preventing / blocks wireless components to join the network.

  Above everything is OK and it connects to the wireless router. Log in from any computer which is, or can be connected to the router with a wire wireless, disable wireless security, make sure that the wireless streaming is enabled and try to connect with no. wireless security.

  When the work turns on the Wireless security.

  Note * people sometimes make mistakes in writing and retype the password for security.

  Another way is to copy in the menu of the router and then paste it when asked of the wireless card.

  --------------------------------------------------

  I really checked and configured every thing and it doesn't work.

  Software firewall application that is not configured to allow local traffic (between the computer and the router is also a possible problem.
  some 3rd party software firewall continue to block the same aspects it traffic Local, they are turned Off (disabled). If possible, configure the firewall correctly or completely uninstall to allow a clean flow of local network traffic. If the 3rd party software is uninstalled, or disables, make sure Windows native firewall is active .

• finished QNetworkAccessManager signal is not shooting in expansion bb10

  Hi all

  I created plugin (native extension) network in which there is a file moc also to load the slot of signal feature. This extension is done following tasks:

  1 entry for Javascript.

  var jsonData = {"url": "'https://cors-test.appspot.com/test ', "timeOutValue": 4"};

  2 launches a thread extension and call the function of demand on the system from here. Here is the code snippet for same.

  void* SignalThread(void* parent) {
      TemplateJS *pParent = static_cast(parent);
  
      int argc = 0;
      char **argv = NULL;
      QCoreApplication QCoreApplication(argc, argv);
      webworks::TemplateNDK *m_signalHandler = new webworks::TemplateNDK(pParent);
      m_signalHandler->doNetworkRequest();
  
      QCoreApplication::exec(); //When I try to remove this line extension stops working and when I try to implement quit, application closes.
      delete m_signalHandler;
      return NULL;
  }
  
  bool TemplateJS::StartThread(){
  
      pthread_attr_t thread_attr;
      pthread_attr_init(&thread_attr);
      pthread_attr_setdetachstate(&thread_attr, PTHREAD_CREATE_DETACHED);
  
      pthread_t m_thread;
      pthread_create(&m_thread, &thread_attr, SignalThread, static_cast(this));
      pthread_attr_destroy(&thread_attr);
      if (!m_thread) {
          return true;
      } else {
          return false;
      }
  }
  

  3 doNetworkRequest function more sends the network request to URL and receive the answer in the slot and return to Javascript application

  4. If no reply is received between the value of timeout then extension sends "operation cancelled" as info application javascript error

  JavaScript application performs tasks:

  1. the request is to have two buttons

  2. the two buttons are hitting the same function and component the same post.

  

  Question:

  This extension works great for first time response and sends to javascript, but when to call the same function second time in the same application, extension sends "operation cancelled" in javascript. For example: if I click on the Test button it sent a response but if I click the Test1 button after getting response Test button it returns the message "transaction cancelled".

  If timeout is removed from the extension, then it returns nothing and stuck somewhere.

  What I found in the extension is, connect statement returns true both times.

  QObject::connect (_networkAccessManager, SIGNAL (finished(QNetworkReply*)),
  This, SLOT (onRequestFinished(QNetworkReply*)));

  By extension, control comes after below line. But not a response to the onRequestFinished location.

  Answer QNetworkReply * = _networkAccessManager-> get (request);

  Please let me know what I am doing wrong.

  This is a very urgent and major of my application implementation.

  Help, please

  Thanks in advance.

  Question is due to every javascript function call new pthread is be created every time and existing thread is never destroyed. However, I assumed that this local variable of pthread_t destroyed but it is not run like that. If trying to kill thread existing manually using pthread_cancel(), application crashes. Application of network function is called in this thread and QNetworkAccessManager slot is never get called except for the first time.

  To solve it, I used a public global variable that allow to create the thread only once and give the signal for the following applications when native code receives a StartThread function call. For signalling, used pthread mutex lock and characteristic signal.

  Here is the code for the function StartThread:

  bool TemplateJS::StartThread()
  {
  
      parseJsonParams();
  
      if (!g1.g_isSignalThreadCreated) {
          g1.g_isSignalThreadCreated = true;
  
          pthread_attr_t thread_attr;
          pthread_attr_init(&thread_attr);
          pthread_attr_setdetachstate(&thread_attr, PTHREAD_CREATE_DETACHED);
          pthread_t m_thread;
          pthread_create(&m_thread, &thread_attr, SignalThread, static_cast(this));
          pthread_attr_destroy(&thread_attr);
  
      } else {
          pthread_mutex_lock(&mutex);
          pthread_cond_signal(&cond);
          pthread_mutex_unlock(&mutex);
  
      }
      return true;
  }
  

  And here's the code must call after event notification.

  void TemplateNDK::Workerthread_waitForNextTime()
      {
          pthread_mutex_lock(&mutex);
          pthread_cond_wait(&cond, &mutex);
          pthread_mutex_unlock(&mutex);
  
          //keeps waiting here until get Signal from StartThread.
          doNetworkRequest();
      }
  

• NotificationGlobalSettings modeChanged signal does not work after restarting

  Hello

  I test this on the OS SDK 10.2.1.1927 for my Alpha of Dev C. My application is headless without long-term stop. The signal and slot work perfectly upon deployment of app on device. My slot is called as soon as there are changes to the Notification Mode of the phone.

  But once the restart of the device, for some reason any. Housing starts running headless, the signal and slot is CONNECTED, because I use the bool to check if the connection is successful. And yes it returned true for the connection.

  But in fact, my slot is not called at all. All changes may not be received. Someone at - it get the same question?

  OK, get it fixed. I don't know if BlackBerry will fix this in the operating system or not, but in case you need, then the another work-around is to delay the connection.

  Delaying the call connect to connect this signal modeChanged (bb:latform::NotificationMode:Type) to your site that handles things when the overall Notification Mode is changed.

  In my case, I tested with a delay of 3 seconds and it does not work properly. After the device restarts, it still works properly.

• Leaves open and closing signals do not seem to work

  Of the clues as to what special qml/qt/cascades magical thing you need to do to get the sheet open and closed signals to deliver?

  The Basic code fragment is

  Sheet sheet is iNewSheet-> Construct();.
  bool ok = connect (sheet, SIGNAL (closed ()), this, SLOT (onSheetClosed ()));
  Q_ASSERT (OK);
  OK = Connect (Sheet, signal (Opened ()), this, slot (onSheetOpened ()));
  Q_ASSERT (OK);
  sheet-> open();

  Both links it seem to work - as in there is no assert.

  The sheet is open ok, but no signal is transmitted

  The sheet can be closed ok, but no closed signal is transmitted.

  We also tried the openedChanged() signal, but that doesn't seem to be delivered either

  If any readers

  No idea what we have changed but the

  Plug finished animation + is now open and the

  Care ended animatng + is now completely closed

  signals which do not seem to work previously now work.

  We can only guess its something to do with the parameters of the method 'connect' or maybe the location of the statements of breeders or possibly using "Q_SLOTS" and not statement 'niche roles' or some other thing random Qt that would be taken by either the preprocessor, the compiler C runtime connect() returns value or other tools applied to the CBC to he mangle in Qt code.

  What exactly is the problem with normal standard C++ interface inheritance for most of these?

• FilePicker fileSelected() signal do not work

  When I select a file in FilePicker, it must issue the signal of fileSelected() with QStringList to the URI of the file, but this QStringList is empty.

  FilePicker::selectedFiles() public method doesn't work either.

  How to know the files selected in FilePicker now?

  This SDK Gold is catastrophic for me.

  Help, help!

  OK, advice to all people using FilePicker:

  In the Archives of .pro:

• signal does not

  I have a sheet declared in my QML file, which has the id "splashscreen.

  When my application is performing a calculation task intensive, I signal of working().

  I have this code attached to the main element of my QML file:

  onCreationCompleted: {}
  _encryptedattachment.finished.connect (splashscreen. Close);
  Console.log ("Connected");
  }

  If I open the application via an invoke on a file that needs deciphering, the

  _encryptedattachment. Working.Connect (splashscreen. Open);

  do not open the splashscreen, even if the event is raised (I checked in the debugger that the code)

  issue of working()

  is executed).

  UPDATE:

  I changed the code as follows:

  onCreationCompleted: {}
  SplashScreen. Open();
  _encryptedattachment. Working.Connect (showSplash);
  _encryptedattachment.finished.connect (hideSplash);
  Console.log ("Connected");
  }
  function showSplash() {}
  Console.log ("open splashscreen");
  SplashScreen. Open();
  }
  function hideSplash() {}
  Console.log ("narrow splashscreen");
  SplashScreen. Close();
  }

  all log messages were printed in the location provided, but the journal has never reopened. Is this a bug in the system?

  OK, I found the problem. Decryption of long-term blocked user interface updates, something I thought was ok because I use an external process to make decryption.

  The solution was to add QCoreApplication:rocessEvents(). to the decryption loop.
