Serializing TCP reference use?

Do I need to serialize the use of my TCP reference?  I.e. I control access (using semaphores) my TCP reference when you use the reference in several process?  What is change of response during the review only read write?

I realize I can create a queue and processes to manage all my writings over TCP, but that the method does not work in my situation.

You have no need to serialize access TCP write, as long as you don't care about the order in which messages are sent. You won't get pieces of two different writings interlaced with each other. However, as Crossrulz said, you will have a problem with TCP read if you need to match messages with messages received.

If you do not use an architecture of response control, it would be reasonable to put written TCP where necessary, but all TCP reads in a single loop, and every time that an update comes through, send it to all stakeholders of the code by a registrant or a functional global variable. The only problem with this is that is dying of the TCP connection, you must reconnect, then you will need a way to update the TCP refnum everywhere.

  • TCP reference is lost

    I'm asumption that the shift register remembers the last value. My shift register isn't passing reference to service TCP TCP. I think it's to do with the installation of the property. Can sombody help the VI does not have a valid connection.

    In your example - you must connect the Port to be a port number valid (non-zero) and the IP address of the device that you connect to.

    I tried to connect to a Server Web (port 80) on my PC (localhost) and it is without error.

    You need to see where the error is actually generated - this is from the first call that opens the port.

    Your shift register will hold very well the TCP reference. As an aside, it is more common to use a while loop with a true cable at the break only one condition loop to "functional globals ' / 'FGVs' / 'action engines" - Although it is functionally identical to your code.

  • Serial number. is used

    Hello    I conducted a total change of PC (motherboard, processor, hard drive etc ... ) , my old PC no longer work and too old ( 15 years of age !).    So I mounted my pc with my new hard drive and installed my LR 6 " entering" its serial number . Then I made an Update.    Upon activation , an Adobe window tells me that " . . The Serial No. is used by the maximum number of authorized computers You must disable another computer within 30 days to use this product"    What is the manipulation that I have done , given that I no longer has my old PC ?  How to deactivate the previous activation?    I looked on my Adobe account in the implementation section, the installation of my LR6 is registered in December 2015 ....    

    I apologize for my bad English, but I don't know that language.

    You must contact the Support from Adobe. They can only help and reset the counter of activation.

  • How can I add a product to my Adobe account or locate serial number by using the Windows registry?

    I can't find my receipt of e-mail on my purchase of CS6 end 2012. (I had a long illness, packed things away and now experience some loss of memory) I want to start again use my CS6 and thought that I would be able to go to my Adobe account to retrieve my serial number. However, my account does not show the order or registration of CS6 under my products even if I received an email from Adobe System Incorporated, welcoming me and thank me for my purchase. Cat officers do not find the corresponding product to my e-mail and refuse to make exceptions or provide assistance to a disability or illness. They say that they must have the right email address associated with the product or a proof of purchase! Other software companies have helped me to locate the serial number by using the Windows registry and then had me answering security questions. I even offered to fix the Adobe email thanking me for buying the CS6, but they said, it would not help! Does anyone know if/how I can add the CS6 to my account and get partner to my email address? Maybe Adobe cat could help me? Also, does anyone know if an encrypted version of the serial number is indeed somewhere in the Windows registry, which make possible for Adobe to help me, if they were ready? This software was very expensive and I don't understand why they won't help me if they could.

    Hi Kay,

    If you view the image on the Web site under license history, you will see the watermark it. Then, simply open this picture in the history of the license and choose "save image to the desktop". Now, open the uploaded image and check it out. It should not have the watermark more.

    In this case I suggest your to check your host file entries once.

    Refer below link (step 3)

    Log, activation, or connection errors. CS5.5 and later versions

    If there is no Adobe entry in your hosts file, try disabling your antivirus software for a while and check (make sure to disable the anti-virus firewall option if available)

  • How to read the Serial Arduino data using labview VISA?

    Hi =). Im a beginner work reading data series from an arduino but im facing... Lets do it step by step

    I built a voltage divider circuit which gives from output
    from 0 to 5V. The output of this circuit is sent to a 0 analog input pin
    of a Committee of Arduino Duemilanove.

    (1) Firstly, I connected the cable to connect to my laptop USB the Arduino.

    (2) I went to start-> control
    Control Panel-> system-> hardware-> Device Manager. Check the Ports (COM
    & LPT). In my laptop I can see USB Serial Port (COM4). Now I know only in
    LabVIEW that I must read the data series COM 4.

    (3) to the side of the arduino, here's the code to read changes in voltage
    entered to analog pin 0. The last line of 'delay' determines the sampling
    Rate of how we want to taste the output of the voltage divider:

    int potPin = 0;    Select the input pin for the output of the voltage divider
    int val = 0;       variable to store the value from the probe

    void setup()
    {
    Serial.begin(9600) (9600);    Opens the serial port, establishes the rate of 9600 bps data
    }

    void loop() {}
    Val = analogRead (potPin); read the value of the voltage divider
    Serial.println (Val);
    Delay (10);
    }

    I slightly modified the basis series reading writing VI... I have
    attached the block schema used with comments. Basically, I tried to read
    data series, divide by 1023 and multiply by 5 to graphic voltage
    variations of the voltage divider circuit.  But Im not getting
    the correct voltage output values. The value of the tension just keeps go
    0 and coming again, as shown in the photo.

    Could you guys please guide me on what went wrong?

    Thank you!

    -you read the data, even if there is no data on the port. If 0 bytes are read => «»

    -in the case of false, you resources VISA wired for the output of channel tunnel?

    -There is no close VISA at the end of the VI resources

    -you're not a loop this VI reading bytes

    I added an addaption of your VI that you should give a try maybe

  • Serial data read using RS 232

    Hi guys,.

    I try to read data using Arduino. these are data am passing my arduino. When I pass these data, only is treated in my labview where is ignored.

    What are the different types of data, I'll spend my arduino

    where XXXX is the binary value based on the State of the component attached to my arduino.

    Please, help me to fix this guy. I have attached my certificate program for your guide. Thank you in advance.

    If you do not use a newline as a termination character.  That's fine, since you can use the > as a termination character.  Then turn on your character of termination on the VISA to set up the Serial Port and set the stop character to be ' > ' (62 decimal, 0x3E).  Then get rid of the bytes to the Port and cable and use a number greater than your maximum message size.  I would go with something like 20.  So what will happen here is the VISA read will read all the bytes up until one of the following occurs: 1) the number of bytes you have provided has been read, 2) the stop character is met, 3) the designated timeout has occurred (the default is 10 seconds).  So use the stop character to get a whole message.  This will allow you to significantly reduce your logic.

    In addition, use a real button instead of a toggle button default to TRUE (which means that you will iterate only your loop once).

  • TCP/IP using CRLF

    Hello

    I use LV2009 for linux.

    I am communicating between my code Java and LV, on localhost, using the TCP/IP protocol. I send you the data: "Hello1\r\n", "Hello1\r\n", "Hello1\r\n" from java to at the end of the LV LV, I use CRLF mode to read the data being sent. I don't get all the data to end of LV. I don't want to use standard mode, because the length of the data being sent could vary each time. I also tried to use immediate mode, but again I don't see not something on LV

    Help, please.
