• Allowing my goal (cRIO) detect disconnection of LAN with host

  Dears

  I develop a standalone application using sbRIO (with RT VI and VI FPGA) and logging data to a host (Host VI) PC...

  the fact is that I need my RT goal to detect if a LAN disconnect has occurred (for example the host pc crashed), he should do a collection of certain data until the connection to the local network is retrieved...

  I don't know if there is something similar to ping between the RT and the host which is done periodically to check the connectivity?

  Help!

  Thanks in advance

  Why not sent a message of "pulse" every second. In this way, if the heart rate does not occur after a certain period, the collection of local data may occur.  Other messages can be sent to recover local data and restore the streaming data.

• Socket TCP detecting disconnections

  I want to take my decision-making if it gets disconnected forcefully, or loses the connection, I read everything I could find on this I have tried different methods but do not find a good, so I decided to ask my question here

  1. I guess that TimeoutSocket.getSocket (ip, port and timeout) do something like:

  Socket s = new Socket(ip, port);
  s.setSoTimeout(timeout);
  return s;
  

  Fine.

  2. no idea what Socket_Connected(). I guess that it performs no operation socket, name is just something to tell him that the plug is connected. Fine.

  3 Thread.sleep (100) does nothing useful, just slows you down.

  4. you should put the read() in a try-catch block (SocketTimeoutException) and in the screenshot, that you should continue in a loop.

  5. your last catch (Exception) should also close the socket.

  You detect many disconnect this way, but perhaps not all conditions (disconnection of the cable is a prime candidate to go unnoticed).
  The only reliable method to find out of disconnection is to write() on the plug (it is a quote from the EJP in an old thread. I check).
  If the Protocol allows that you and you want to be 100% sure, do it periodically (in SocketTimeoutException Manager).
  Send some kind of small NOOP for the package, which will not take the server as any other thing.

• Detect closed netstream

  Hello world

  
  

  I have problems to a netstream object is closed.

  
  

  The"NetConnection.Connect.Closed" fires on the NetConnection object but not on the NetStream.

  
  

  How can I get the targeted NetStream?

  forNetStream object event.info.code will be "NetStream.Connect.Closed". I don't know exactly how to get this object, but try to check property event.info.stream.


• Detection of disconnected by mistake the peer socket

  Is there a way to detect the error 'socket disconnected by the peers' for a NV who subscribes only to? When interacting with a NV (either by a read or write operation) sometimes this error is thrown in this case can be easily intercepted, but my interest is to detect this error for a NV that is not read or written, but only subscribed to.

  I looked into it further, and the only thing we can offer is the event NetworkVariableManager.PropertyChanged is fired by the settings property.  She will be thrown on the very basic connection on the local machine breaks, such that the network cable is disconnected from the local computer.  This isn't entirely what you want, but it's the closest thing we can offer.

• CD/DVD drive is not detected, the disc is missing or disconnected

  Well I have not tried to play anything or anything either burning on my laptop in a while and all of a sudden is not working more I followed suggestions on the microsoft site, but when I went into Device Manager to check on my drive anywhere it lists same CD-ROM/dvd-rom I'm so confused, I don't know what I tried to use microsoft not fixed and it's just as stuck as I am all he tells me it is than its disconnected or missing and cannot be found.

  Oh and while I'm asking questions my sound stopped working a few months back the small volume in the lower right corner icon has an 'x' next to him now and he says: no audio output device is installed, I tried following the suggestions online for this with no luck either. I hope that its not anything internal since I just had the motherboard replaced by a few months before this happened

  Thank you very much I hope you can help!

  Hello

  Well it still might be hardware or wiring.

  Restart to make sure that nothing is inteferring with the process.

  Step 1: Please make all underneath the same if you've done it before as it's often the total of the process which
  solves the problem.

  Try this - Panel - Device Manager - CD/DVD - double-click on the device - driver tab - click
  Update the drivers (this will probably do nothing) - then RIGHT click the drive - UNINSTALL - REBOOT
  This will refresh the default driver stack. Even if the reader does not appear to continue below.
  
  Then, work your way through these - don't forget the drive might be bad, could be a loose cable or
  slight corrosion on the contacts (usually for a laptop) and other issues.

  Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both

  Did you follow the Troubleshooting Guide for the reader who still does not work? There are some registry entries
  that the troubleshooter does not, and those who "could" be the cause.

  Check with your system manufacturer Maker and device for possible firmware updates and the good
  Your player registry entries.

  Here are the keys in my opinion, are those in question - for the reader of CD/DVD subkeys of course that he will be

• Detecting when Bluetooth is disconnected

  Hello

  I have a camera I'm trying to connect with my BlackBerry using Bluetooth.

  I am able to connect using the Connector.open (info, Connector.READ_WRITE);

  I can also read and write using the input and the output stream.

  However, I must be able to detect when the port is disconnected from the remote device. I was thinking of using BluetoothSerialPortListener. To use this I try to connect to the device using this method:

  listener = new MyBluetoothListener();  
  
  _serialPort = new BluetoothSerialPort(info[i].toString(), BluetoothSerialPort.BAUD_9600, BluetoothSerialPort.DATA_FORMAT_DATA_BITS_8 | BluetoothSerialPort.DATA_FORMAT_PARITY_NONE | BluetoothSerialPort.DATA_FORMAT_STOP_BITS_1, BluetoothSerialPort.FLOW_CONTROL_NONE, 2048, 2048, listener);
  

  This doesn't seem to work. The above call works fine and I get not all exceptions. However, I didn't also get the recall of deviceConnected() my interlocutor.

  I see the following in the console output, and nothing else after that:

  BT: allocSerialPort 81159234
  BT: sdpAddRecord
  BT: allocSdpAttributeData

  Is there something I'm missing here?

  To summarize, I have two questions:

  1. Why isn't the connection using BluetoothSerialPort to work?

  2. assuming I can't that work is there a way I can detect a lag when you use the Connector.open () method?

  Thanks in advance for your help.

  I connect to a Bluetooth device using code very similar to yours, with two exceptions:

  (1) you use info [i] m:System.NET.SocketAddress.ToString () as the first parameter, I just use the equivalent of the info [i]

  (2) I use BluetoothSerialPort.BAUD_115200,

  The listener receives disconnects because I expect.

  The messages that I see when you debug this re as follows:

  BT: allocSerialPort 814ee52c
  BT: BTEVENT_LINK_CONNECT_CNF
  NET. RIM. Bluetooth: DC00
  BT: BTEVENT_LINK_POLICY_CHNG received
  NET. RIM. Bluetooth: EC00

  This test has been done on a 8900 4.6.1.199 is running.

  I hope this helps.

• Remote Desktop - due to the protocol error detected at the client level (code 0 x 1104), this session will be disconnected

  Original title: Remote Desktop

  I get strange messages when trying to do Remote Desktop (and also connect using Logmein). Sometiems I get this:

  Due to the protocol error detected at the client level (code 0 x 1104), this session will be disconnected.
  Try to reconnect to the remote computer.

  Sometimes:

• Cannot detect when my FLV netstream stops.

  I want to detect the moment where my FLV stop and jump to another video. How can I do this? My current code is:

  The first video plays very well, but he stops just when it's done.

  Setting up my netstream and play my video

  var nc:NetConnection = new NetConnection();
  NC. Connect (null);
  var ns:NetStream = new NetStream (nc);
  ns.addEventListener (AsyncErrorEvent.ASYNC_ERROR, asyncErrorHandler);
  var vid:Video = new Video (320, 240);
  this.addChild (vid);
  vid.attachNetStream (ns);
  NS. Play ("video0.flv");
  ns.addEventListener (NetStatusEvent.NET_STATUS, netStatusHandler);

  That's what I thought I should do to detect the stop

  function netStatusHandler(event:NetStatusEvent):void {}
  {Switch (Event)}
  case 'NetStream.Play.Complete ':
  NS. Close();
  NS. Play ("Video2.flv");
  }
  }

  Manages asynchronous errors by ignoring

  function asyncErrorHandler(event:AsyncErrorEvent):void {}
  Ignore
  }

  Thank you!

  Sorry, I forgot to mention that you are listening wrong event code:

  case 'NetStream.Play.Complete':-there is no full on NetStream

  It should be

  case "NetStream.Play. Stop«:»

• NFC - how to detect the disconnection?

  Repost - it was in the wrong forum. :

  Just get started with the development of the NFC.

  I've been through the examples and am able to read basic NDEF tags.

  The only thing I don't see is how to detect where the NFC tag disappeared.

  Y at - it a reminder or another trigger?

  Or I will just try to do an operation (read, write, etc.) and then capture the execption?

  Thank you

  Richard

  Hi, you are right that there is no reminder of this event (tag moves out of the field). As you suggest, after detecting the tag in the box, you must handle errors that come from reading or writing to it.

• Network by Extended client disconnection detection

  Hello

  I someone can help me solve this problem relevant to the capture of disconnection from network client extended it would be a great help.
  
  Thank you and best regards,
  Sura

  Hi Sura,

  You will not be able to receive notifications of any listener to cache network disconnection. The client extension connects to the proxy. Therefore, according to your usecase disconnecting from the network means disconnection of customer enhancement proxy.

  You can listen proxy disconnection notifications by implementing a MemberListener in customer enhancement. The Extend customer has only one Member, and it is the connected proxy. Therefore, if the proxy is disconnected (or network is disconnected) memberLeft event triggers.

  MemberListener proxyListener = new MemberListener() {}

  {} public void memberLeft (MemberEvent arg0)
  disconnecting from the network
  }

  {} public void memberLeaving (MemberEvent arg0)
  }

  {} public void memberJoined (MemberEvent arg0)
  }
  };

  cache.getCacheService () .addMemberListener (proxyListener)

  It will be a solution for your usecase...

• AS3 how can you detect if someone shoots their camera into the USB port?

  In AS3 if the SWF Gets a hold of the camera of someone successfully and they begin streaming video everywhere and everything, but then halfway, either they wiggle accidentally their camera into the USB port, or the camera just sort breaks down, or something like that, how can detect you on the user side?  I tried using event listeners and different variables of Mark also every five seconds, but none worked. any of the public properties of the camera or its events seem to be acting funny of all when something happens like that.  And apparently you can just keep analysis the computer for devices (for a good reason, I suppose).

  Is there something I'm missing here?  Is it possible to detect the copy of a user of a SWF file (PF or AIR, but much more important still FP) when their camera has effectively stopped as the result of something goes wrong, like them what she wiggling the computer by mistake?  If so, how?  Thank you!

  Run your code and disconnect your camera. What are the common properties of it? Stop your flow? To return only a framework of specific color? These things can be used to detect, but you are right when you say that you can not detect more than a loss of packets from a NetStream object.

• Detect diconnection peers

  Hello

  I am doing an application of counterpart to detect when another connected peer disconnets (for example, just close the browser window).

  I tried to add all open NetStreams NetStatusEvent.NET_STATUS and I also tried to add the handlers onPeerDisconnect NetStream clients. None of them fires when peer disconnects.

  However, onPeerConnect works perfectly fine for me.

  Any ideas?

  Thank you!

  I think when a counterparts connection closes, you will see a status of NetStream.Connect.Closed

  event on the NetConnection.  Then, install a NetEvent on the NetConnection instance manager and look for the NetStream.Connect.Closed events.

  This special event will have a property called 'stream' that indicates which NetStream closed.

• Thunderbolt display is no longer detected

  I have a late 2013, MacBook Pro and a 27 inch Thunderbolt display, bought in September 2014. I use the screen without problems since then. But today the display is no longer detected. I got the MacBook disconnected from the screen, which has been briefly disconnected from the sector. (It was a power outage scheduled as it happens, but I don't see how that makes a difference).

  Now, when I connect display of the power of the lead part works fine but the screen does not illuminate. To the search, in the report of the system, the Thunderbolt Bus shows two Ports both with "no device connected". I have a Thunderbolt ethernet adapter and shows.

  I tried all the usual troubleshooting steps: disconnected power for a few minutes, resetting the NVRAM, reset SMC. A ran Diagnostics from Apple on the MacBook - all very good. I don't know what I can do. The Thunderbolt connector is slightly warm to the touch, which I think is always the case.

  Everyone you have other ideas please?

  Hey donnysp,

  If I understand correctly, the external display Thunderbolt is not recognized by MacBook Pro.  Looks like you already have a troubleshooting. I recommend you to read this article, it may be able to help solve the problem.
  
  

  Check the connections on your Mac and external screens:

  • If you use an Apple laptop computer, try to connect the AC adapter.
  • Make sure that the power cable from the external display is connected correctly and that your display is enabled.
  • If you are using a Mac Pro (end of 2013), make sure that your screens are plugged into the right ports.
  • If you use a hub of display, Cabinet or "KVM", try to connect the video cable from your screen directly to your Mac instead.
  • Unplug the video cable where it plugs into your Mac, then reconnect to reinsert the connection.
  • If you are using a video card, unplug the video adapter on your Mac, then reconnect to reinsert the connection.
  • If you use multiple video cards to connect your screen (the cards are "chained"), testing connection of the screen by using a single adapter if possible. Some video cards may not be linked together. For example, a mini DisplayPort to DVI adapter may not be connected to an adapter DVI to HDMI.
  • If your screen has more than one video connection, see if you are using another connection on the display works. If possible, check if you use a different view or a different adapter works.
  • Try using another cable that you know to be in working condition. Check with the manufacturer of the screen to make sure that you use the cable they recommend.

• iPad and iPhone 6 disconnection from the Wifi after IOS 10 improvement

  A problem with maintaining connectivity to my home wifi network, I noticed on my iPad and my iPhone 6.  I'll do an alert on the iPad (which is Wifi only, not LTE) that it cannot detect the Internet. He sees my router but says 'no Internet connection '.  Same thing is happening with the iPhone 6, which translates by he's going to LTE and eat in my data plan.  In both cases, I have to re - start devices and reconnect to my wifi network.  I'm having no problems with non - IOS devices (Samsung Nook, a Roku player and a Smart TV) with my wifi network at home - two Apple devices I am owner of running IOS 10.  Is there a problem with the maintenance of wifi connections?

  Hello rm2static,

  Thank you for using communities of Apple Support. It is my understanding that your iPad and iPhone 6 have been disconnect from your home network after updating to iOS 10. I can surely see how it would be about, so much more than other devices are connect well. I'm happy to help you to get this resolved with you.

  First of all, I recommend you to reset the network settings. Tap Settings > general > reset > reset network settings. This operation brings back all the network settings to the default settings, including the Wi - Fi networks and passwords, cell settings, VPN, and APN.

  If the problem persists, try with another Wi - Fi network. Additionally, make sure that your Wi - Fi router has been updated with the latest firmware.

  See you soon!
