• Threading and reuse of the node to call using reference of buffers (of the required adhesive tape)

  I tried to get the following information in the public domain for years and now that I have the answers, I'll share with those who might be interested.

  Caveat!

  Wrap your head in tape before reading just for the sake of security.

  My two questions were;

  (1) may LV re - use tampons of VI calling when you use VI serve call by reference?

  (2) is used when the use of call by reference UI thread?

  

  1 when you call a VI using the call through the reference node, the data in the pane of the copied or is node connector - this online as it would be with a Subvi properly implemented?

  Short answer: it's somewhere between the two.

  Long answer:

  The compiler does not know what will be called VI, but there a hint:

  the reference connected to the node of the call by reference. He uses to get the 'Prototype' for the call. Therefore, for optimal performance, use a prototype that has the same 'characteristics placeness' as it is called VI. That said, users don't know what are the "characteristics of the placeness.

  Before getting into the details, I will say that the overhead of these copies should not matter much unless it's a large data structure (a table with lots of items.) or a cluster/class with many fields or containing large networks etc..

  Example 1:

  If the prototype does not change the data, then the compiler assumes that the crux of the call by reference will not alter the data. However, at runtime, a check is made to see if the real called VI will modify the data. If Yes, then a copy is made and past so that the original data can be modified.

  Example 2:

  If the prototype contains an entry that is wired through an exit so that both input and output terminals can use the same buffer memory, but running an audit determines that the real called entry and exit VI do not share a buffer, then a copy will be made from output of the actual call to the original screws (combined input and output) buffer.

  I should also mention that, even with this behavior "are trying to get along with the prototype", it is not always possible to obtain good performance as a Subvi ordinary call. For example, if you have a situation where the prototype does not change the data and passes it through to an exit and then the compiler must assume that the data is changed (because, as in example 2, there are screws that may change even if the called real VI is not).

  And there are a few caveats:

  (1) this behavior "using a prototype" was new for 2009. Before that, we used a method more naïve data of passage that took all the entries will be changed and no outputs don't share a buffer with an entry.

  (2) this behavior can be changed in future versions, if we find additional optimizations.

  (3) this behavior is the same that we use for the dynamic distribution live (when you use the classes in LV)

  (4) If you want to create a VI can be used as a prototype, you can use the features of the Structure in Place to control the "characteristics of the placeness', namely the element nodes in and out of the border, the function"Mark as modifier"border nodes (note the pencil icon on the item), and the node always one copy.

  (5) the prototype is only the first reference ever connected to the node of the call by reference. So if you make a new prototype VI, you can just make a reference out of it plug into the crux of the call by reference. I suggest to remove the node from the call by reference and file a new.

  (6) for remote calls, we still "making copies" by transmitting data over a network.

  I hope that this helps, if you want information/clarification, so feel free to ask.

  2 - is the call made by the reference to run in the user interface thread node? If the call is made by a remote machine via ethernet, thread that host (the computer that makes the call by reference) runs on and thread that executes the target (the machine that contains the file VI) on?

  In the case of premises, the appeal made by the reference node does not require the user interface thread and may work in some thread the VI wants to run in.

  When you call a remote VI, the appeal made by the reference node uses the UI thread (detailed below) on both the client and the server.

  The client uses the UI thread to send the request to the server and there still when the response comes back. The user interface thread is not blocked during the time between the two.

  The server receives the TCP message in the UI thread, and then starts the call to the UI thread. The server also uses the user interface thread to send the response to the client. The user interface thread is not blocked on the server during execution of the VI.

  I hope that people find it when they need it!

• How to get the current location in the event thread?

  Hello!

  Can U pls tell me how to get the location where the thread object, it is in method() execution of MenuItem. PLS, tell me-

  I also used the different thread for the getLocation() method. But I do not have the coords of geo location...

  PLS, suggest me-

  My code is as below:

      private MenuItem getGeoCodes=new MenuItem("Current Coords",100,1){
  
                               public void run(){
                                   double[] coords=getLocationCoords();
                                   this.wait(12000);
                                   System.out.println("Latitude :"+coords[0]+" "+"Longitude:"+coords[1]);
                               }
  
                   };
  
      private double[] getLocationCoords(){
          Criteria criteria = new Criteria();
          criteria.setHorizontalAccuracy(500);
          criteria.setVerticalAccuracy(500);
          LocationProvider locationProvider = LocationProvider.getInstance(criteria);
          Location location=null;
          new Thread(){
             public void run(){
                     locationProvider.getLocation(60);
             }
          }
          QualifiedCoordinates qualifiedCoordinates=location.getQualifiedCoordinates();
          double[] coords=new double[]{qualifiedCoordinates.getLatitude(),qualifiedCoordinates.getLongitude()}   ;
           return coords;
      }
  

  But I myself NullPointerException. Coordinates get successfully, if we run the location capability in different function, rather than the event thread.

  Please help me-

  In my opinion, which may be too complicate things a bit. I think he's trying to do is register a LocationListener with his object of LocationProvider. Callback methods, send a message to the UI event thread as follows (no need to spawn threads):

  UiApplication.getUiApplication().invokeLater( new Runnable() {
      public void run()
      {
          // This code will execute on the event thread
      }
  });
  

  EDIT: If your interval is short, you can consider implementing this executable as a class and store an instance in the front.

• Question about the event thread

  Hello world

  I need to perform a lot of Http 'Get' and 'Post' requests If I'm not directly interacting with the UI (event thread), then I need to put the class managing http requests in its own thread?

  Any advice would be appreciated, thanks!

  You should not run any operation (such as an HTTP GET or POST request) blocking or no matter how long processing thread in the case. If you do, you run the risk of allowing the event queue overflow while you have this thread do something else, which will cause your app ending with the system.

  You must always start a worker for any HTTP operation thread.

• iPhone 6 more issues activation and network on the latest iOS 9.3.2

  I have an iPhone 6 it is having problems with Activation and networking connectivity. I activated via iTunes and updated to the latest iOS 9.3.2 this morning. The phone remain active for a period of time and then come back to need activation.

  Using WiFi it is full bars but no connection. I'm typing this from my iPad on the same WiFi connection, so not the network. If I turn off WiFi and cell there still no connection. The phone will receive calls (even when stuck in the activation state) and can make calls after you have enabled from iTunes.  She was released a couple of times, but always the same question.

  I tried to erase and reload from iTunes to the top, but the restore function requires that find my iPhone service shut down on the phone and this step requires access to complete network.

  Try the following steps:

  • Try connecting your device to your computer and launch iTunes. Choose your device and click on summary > update.
  • If this does not work, make sure you have the latest version of iTunes installed on your computer and restart your computer.
  • When it restarts load iTunes and try to select your device and click on summary > update again.
  • If this does not work, it's time to try a restore. Press and hold the sleep/wake and home buttons on your iPad or your iPhone until iTunes gives you the option to restore your device.
  • When it's over, you can restore a backup, and you should be good to go with 9.3 running iOS.

• Options, advanced, "there's no ' disk space and network"?

  I searched "how to compact the received messages on mozilla" the answer say ' options, advanced, and then click on 'network and disk space' it is NONE 'disk space and network"not anywhere on advanced settings, 'general' to all that. This is not the first time an answer to my question produces the same results, not on my computer.

• Edit event managed by this case in LabVIEW 2013 does not show the specifiers of the event, Event Sources and events on screen resolution 800 x 600

  Edit event managed by this case in LabVIEW 2013 shows not specifiers of the event, Event Sources and events on screen resolution 800 x 600.

  As far as I know, the list of supported resolutions is determined solely by the graphics card. It is possible that one used by the PC supports only 800 x 600 as maximum resolution, even if you plug an external monitor.

  Like Dennis suggested, the recommended option would probably be to develop on another PC and only deploy an executable for the industrial PC. That's what we do with our systems (although not because of this problem, but because it makes sense. There absolutely no need to have the IDE installed in most of our systems).

  Other options:

  1. See if you can get an update of the driver from the manufacturer to solve this problem.
  2. Plug a USB Monitor with its own driver.
  3. Try to hide the taskbar and make the smaller title bar in the hope that the bug manifests.
  4. Try remote access in the PC. I think that some remote access programs allow you to specify custom resolutions that are not affected by the original drivers. Remote Desktop seems to be a likely this option even if it has been awhile since I've used it.
  5. Check the BIOS. I saw at least one industrial PC where there was some settings in the BIOS to control the resolution, but I don't remember the details, and it was quite limited. I think that in this case, you can change the resolution, but then the image does not fill the entire screen.

• Received a call from someone claiming to be from Microsoft - error in MS Windows event viewer and warnings

  I just got a phone call from someone claiming to be from Microsoft.  He directed me to go to MS Windows event viewer and County errors and warnings in the Applications and the system section.  Then he asked me to let them access my computer and fix any problems that would be 'crash' of my computer.  When I refused him access said he couldn't help me and hung up.  I do not think that it was Microsoft but are ratings warning and error a problem?  I use Windows XP.

  Kudos to you 1Grizzly, you have made the right choice. Microsoft does not make unsolicited support calls or send emails to customers, offering support.
