• Good method to reset the tcp connection after timeout error

  I have an application that I build that communicates with a Modbus TCP device.  If a communication occurs error I wish I could reset it TCP communication.  What I have is a control that raises an event when pushed.  In this case, I have a sequence that closes first the tcp connection and then opens a new connection.  My application starts and works very well.  To test the reset function, I removed the ethernet cable from the camera and waited until a timeout occurs.  I plugged the cable reset back to and pushed my control. Sometimes the reset will take place, but most of the time I'll get a timeout in the TCP vi open error.  After that, the only way I can establish communications must leave my application, disable and then enable the network device.  Then, when I restart my application I have communication with my camera.

  Any help would be appreciated on how I should be reset my TCP connection.

  Thank you

  I've attached an example vi (LV10) that shows just the connection TCP and Reset.  An error occurs when you try to run the open in the event of reset tcp protocol.

  As writing that your code should be fine. There is nothing inherently wrong with it. However, depending on the device, you communicate with you can try to restore the connection too quickly once you have closed the connection. The device allows multiple connections to it and may require some time to clean up the things on his end after you close a connection. An experimental basis try wait little time between TCP and the TCP Open shut it down. If possible you can try using Wireshark to see what is happening on the network. It may be useful to diagnose what is happening.

• Problem of test Signal before using the TCP connection

  Right now my application uses a SocketConnection TCP to communicate with a remote server.  It works fine, but I'm trying to make sure that my program can correctly handle the situation to move to an area with no coverage.

  When I run my application, if I uncheck the box "on the cover" for GSM and CDMA under Network properties, my app fine until it calls the OutputStreamWriter.write () function to send something on the socket connection.  I have it in a try/catch block, but it just seems to hang instead of throwing an exception.

  How can I check the signal before attempting to send data on the SocketConnection?

  To facilitate clear life upwards, here's the order of what happens:

  1 application starts on the cover.

  2 SocketConnection made successfully.

  3 OutputStreamWriter successfully SocketConnection.

  4. coverage is lost

  5 OutputStreamWriter.write () is called, but freezes instead of throwing an exception.

  The socket connection output stream write operations do not throw an exception when there is no coverage is the correct behavior. That's because on cellular networks the IP tunnel to the carrier (and therefore the TCP connections on this tunnel) survives loss of coverage. For example, if your application opens a connection TCP from a BlackBerry, then the BlackBerry loses coverage, then take cover, say, 1 minute later, the TCP connection opened by your application will continue works fine, unless intermediate network component or your server closes the connection due to inactivity.

  Hi JDSoor,

  Thanks for posting. Two or more instances of the service Msiexec.exe cannot be launched at the same time for two different products. An install or repair processes should finish before the other process can be launched. Go to processes in the Manager of tasks (so press CTRL ALT + DELETE) then press the processes tab and look for to MSiexec.exe and press "end process." You may need to do more than once.

  I hope this helps. Let us know if this or do not resolve your problem.

  Thank you

  Shawn

  It should not, but you will need to download the right software to use. Adobe Acrobat Reader is what you are currently using. This is why you don't have the tools you are used to.

  Adobe Acrobat (not Reader), that's what you signed up for. He has the tools, you need and are a completely different, even if application you may have initially subscribed by using Adobe Acrobat Reader.

• What happened to security.warn the settings about: config. They are absent in FF25. Help, please!

  Hello

  I'm upgrading from Firefox 15 to 25 of Firefox.
  I used to be able to set the following security warnings in: config.

  Security.warn_entering_secure
  Security.warn_entering_weak
  Security.warn_leaving_secure
  Security.warn_submit_insecure
  Security.warn_viewing_mixed

  No more. Looks like these are missing from Firefox 25.
  Help, please! Urgent.

  Thank you.

  warnings about the output of a secure site disappeared completely, you would have to look out for the security at the beginning of the address bar indicator to get that information on a site: https://blog.mozilla.org/ux/2012/06/site-identity-ui-updates/
  
  or use an extension like this for better visibility: https://addons.mozilla.org/firefox/addon/safe/

  the dialog box warning about sending data on a channel not secure to a secure site is still in place.

  Your firewall is not recognizing the new version of Firefox. Remove Firefox from the list of allowed programs in your firewall, restart Firefox and go to any website, give Firefox the permissions he needs access to the internet.
