TCP listen accepts only 1 packet

Similar Questions

• The TCP Listen.vi doesn't seem to detect reliably all the elements on the network.

  I use a network dedicated to four devices. When I run the TCP Listen.vi it does not always detect all four of the devices. Sometimes, he gets all of them and in the worst case, a single device.  The question I have is to detect if it's the vi or if there is that something screwed up with the network, or with devices.  I bet on the devices, but the development engineers always tell me it perfect stuff. From time to time, I have a hard time to believe for some reason any.

  Someone has ideas how to analyze where is the problem?  I am a newbie with TCP stupid mistakes are not only possible, but likely.

  Thank you

  Nathand,

  I think you have already revealed the possible source of the problem. I think that I do not use this thing correctly based on your information.  I'll go back and rewrite things and see where I get.  And thanks for the tip of Wireshark. Never heard before.

  Thank you!

• How to accept only 4 or less than four hexadecimal characters in the control chain

  Hello

  I want to accept only up to 4 hexadecimal characters in a control of the chain. I don't want to use the property "hex display.

  How is that possible? I have the string control key down? event event, I tried with the regex [0 - 9a - fA - F] {4}, but then I have to accept, left, right, delete, BACKSPACE, house keys as well.

  I agree with Dennis that you seem to be making life difficult for yourself.  However, did you ask the equivalent (as I understand) "How can I allow the user to type '1', '2', 'Ctrl-A', 'B',"Ctrl-C","D"and get this recognized as the string"12BD".  If you really want to do, here's a way (I was lazy and left the response as an array of strings of 1 4 characters).  I use PlatMods to exclude have any 'change' other key moving downwards, convert the digital Char to a string, then count the letters of acceptable Hex and conditionally, add them to the results matrix, stopping when I have 4 characters.

  Is it possible to let the user just write in Arabic in the af input text?

  If he enter English tank when you use keyboard ENG that I want to prevent this event and not let him write without error msg and if it helps keyboard AR I want let write

  Thank you.

  You can implement something like this using javascript. You should prevent the addition of English characters of:

  -Keyboard

  -By using ctrl + v (in case you have copied English words)

  -Using right-click + spent (in the case where you have copied English words)

  To do this test to track the following:

  1 - inside af:inputText add 2 clientListener. One to accept only Arabic characters and the other for the deactivation of ctrl + v as:

  2 - Add af:resource with type = "javascript" and inside this write three functions:

  -an acceptArabic function.

  b disabledPastFunction

  c disabled right click on the page.

  as:

  
  
          = 1560 && k <= 1610) || k == 32)
      {
      }
      else
      {
        evt.cancel();
      }
    }
    ]]>
  
    function disabledPastFunction(evt)

• Attribute with forumula to accept only 20 characters

  Good evening, Oracle,

  Currently I have an attribute called "Activity_Name".  I have a team that has an ETL process that accepts only the attribute of max 20 characters in length.

  So I have another attribute called "Activity_Name20".

  So basically, if an article in "Activity_Name" under the characters 'Activity_Name20' will assume this value.

  If there is a value in "Activity_Name" it is more than 20 characters, "Activity_Name20" will assume the first 20 characters.

  However, the formula I have with it is not working and in fact, preventing me from trying to break into the hierarchy.

  Someone at - it something similar to a client only? Could use some pointers.

  Thank you!

• JavaScript for auto tab.  Is it possible for me to format the fields to accept only numbers?

  I created a form that uses the JavaScript for the auto tab. Is it possible for me to format the fields to accept only numbers?

  ______________

  Here's the Format Script

  ______________

  Function at the level of the document

  function tab_next (Text5) {}

  Move to the next field relied on entry

  or the user has clicked outside the scope

  or if the number of the character is the character limit

  If (event.willCommit |) AFMergeChange (event) .length = event.target.charLimit) {}

  getField (Text5) .setFocus ();

  }

  }

  ____________

  Here's the script of strike

  ____________

  AutoTab to the field 'Rem5 '.

  tab_next ("Text5");

  The classical function "goNext", JavaScript - setFocus method for the tab to the next form field , used control built-in number format.

  AutoTab (doc, event, cNext) function

  {

  Calling the routine integrated to allow only numbers.

  AFNumber_Keystroke (0, 0, 0, 0, "", true);

  If we have filled the field completely, skip to the next.

  If (event.rc & AFMergeChange (event) .length == event.target.charLimit)

  doc.getField (cNext) .setFocus ();

  }

  The custom keystroke script:

  AutoTab (this, event, "Rem5");

  Be sure to set the limit of characters for the field. You can also add the script of blur:

• How to create the text field that accepts (only Alphabates no numbers or numbers)

  Hey guys,.

  I just want to know how to create a text field that accepts (only text without characters or numbers)?

  I want to insert validation that field only accepts the alphabates no number or numbers are allowed!

  
  Thanks in advance!

  In the designer, click the field that you need to validate and open the script window, together the menu show drop-down list to validate in the drop-down list and place the code in the script window. Make sure that the language is Javascript and run is defined on the Client. If you don't see the script window goto window-> Script Editor Menu item.

• Restrict a TextInput to accept only numbers from 0 to 250

  I want to restrict a TextInput to accept only numbers from 0 to 250. I know that I can use limit to a certain extent, but all I can do is limit to 0-9 and use maxChars to 3 that allows any number from 000 to 999.
  
  I think I could use the TextEvent.TEXT_INPUT and then write the code that will convert the text of the event (i.e., the text entered in the textInput component, before it is actually added to the text of the textInput component value) such that I allow not values greater than 250, but I'm not sure of what would be the code. Does anyone know an easier way to do this?

  Use the change event to monitor the input value and if it is greater than 250 (after tapping the property text as a number), assign the property of text to be "250".

• TCP Listen.vi delay application

  Hello

  I'm having a problem using the Subvi 'Listen.vi TCP'.
  I need to connect my client to the server (which the Sub question VI) However, I just can't stop the application that is running on the server just to wait for the client to connect, the client must connect to the server at any time without delay or stop.

  I enclose two screws, to illustrate what I'm saying.
  The first (main) is called 'test', which has the other sub - VI 'Aguardar client"(customer waiting in Portuguese).
  What I want to do is to click on 'Connect' without stopping the random number generator.

  Anyone know how to do it?

  Need you a parallel task waiting for a client to connect. Once connected if you need this issue and wait for other connections, you will need to generate a job manager. Look for the dynamic call screws in the example to see how you can accomplish this.
