  Hello I am struggling with this problem for 2 months... They get help from different I thought I solved the problem, but of no use yet I stand on zero

  Problem: I need to get data on USB high speed HEXAGON shaped (coming in hexadecimal and be stored in the text file to the hexadecimal format as each hexadecimal value online different I'll also to attach the file)

  Get us ASCII on series or VISA read but when trying to convert to hex as shown in text file making it slower to deal with code, I know that my VI will have to improve more... I'm waiting for suggestions

  Need urgent help...

  Thanks in advance

  Hi Ali Afzal,.

  I think that the attached example can work for you. If not, then try the solution with sending the data to a parallel running the loop and store it there.

  Yes, you can write like try (), it returns a string, and you can write that string to the file.

• TCP Read and Write at the same time

  Hello everyone,

  I have a question about parallelism in TCP connections.

  I know that it is possible to read and write on the same connection ID.

  So, if you ReadTCP and WriteTCP block each other, if you use the same TCP connection ID?

  Or to request more precise if I run two while loops, in parallel, with one end by calling WriteTCP and the other called ReadTCP.

  one of the delay of loops (or block) will be the other if both loops call their VI TCP at the same time right?

  The system is Windows 7 and Labview 2012.

  Kind regards

  Sebastian

  They are perfectly parallel.  Just write in one and read it from the other.  There is no conflict.

  See My TCP articles for more details.

• Need help for reading in parallel on the same interface and writing XNET

  Hello. I need help to configure CAN interface to write and read from the same interface.

  I use NI PXI-8513/2. I use CAN1 as interface.

  My had TO send status messages CAN every 100ms. I have to read in order to return akntoowlege to keep DUT CAN interface happy and not make mistakes.

  So, I want to open Strim Session and readall frames in the loop. At the same time, I need to be able to write in a frame HAD at the time...

  I only need to read one picture at a time too, but since I know the ID, I can pull it from the stream.

  What I'm confusing all is how to put in place the same CAN1 interface to be able to write and read in parallel.

  I think I would get errors that interface is already in use.

  Since I'm new to CAN, I was read and write only when necessary. But, sometimes I was getting errors on my messages. Sometimes I get message, sometimes miss me. But, when I run CAN test criminal as sniffer he sends and written every time. I was told it's because it recognizes all messages.

  I opened to suggestions of how best to implement the interface.

  I guess I can use CAN2 and separator to work around this problem, but I would use an interface if possible.

  Thank you

  Hi Rus,

  The XNET hadrware takes care of most of the low level of detials for you. The reading and writing of the circuits are both connected to the bus at any time. When you write to the hardware it will try to put a frame on the bus at the first opportunity he can. If the frame loses arbitration material re - will attempt to send the frame up is successful. Reception equipment monitor activity on the bus, regardless of what it conveys. The material received will usually throw a framework that was sent by communication equipment, but there is an Echo property pass to circumvent this behavior too.

  Take a look at the example of the expedition: MAY-> NI - XNET-> Sessions-> multiple Sessions Intro-> CAN even exit entry framework Port unique Point.vi. Keep in mind that this example you will need to use a second CAN interface to recognize frames, it transmits. I would recoment against the example CAN output Frame Single Point which would mimic your ECU if you choose a type of cyclic frame running this example.

• Extract PDF form data using JavaScript and write in the CSV file

  I received a PDF file with a form.  The form is * not * formatted as a table.  My requirement is to extract form field values and write into a CSV file that can be imported into Excel.  I tried using the menu item "Merge data from spreadsheet files" automated in Acrobat Pro, but the release includes both the labels and values.  I'm mostly just interested in the form field values.

  I would use JavaScript to extract the data from the form and learn JavaScript write CSV file (since I know what should look like the spreadsheet of end).  I got regarding the extraction of the fields in the form:

  this.getField("Today_s_Date").value;

  And the rest of this post: http://StackOverflow.com/questions/17422514/how-to-write-a-text-file-in-Acrobat-JavaScript , I tried to write to CSV using:

  var cMyC = "abc";

  var doc = this.createDataObject ({cName: "test.txt", cValue: cMyC});

  but I get the following error:

  "SyntaxError: syntax error".

  1:Console:Exec ".

  Ideally, I don't want to use a third-party tool online to make, because the data are sensitive.  But please let me know if you have any suggestions.  The ideal output is a CSV file that an end business user can open in Excel to see the format of spreadsheet of his choice.

  Did anyone done this before?  Open to hearing alternatives as well.  Thanks in advance!

  The code you have posted works fine for me in the JavaScript console, so I suspect the problem is something else. Where did he put the code and y at - he seized another code?

  In addition, if CSV is not a strong requirement, I would say that you use delimited by tabs instead. Fields normally cannot contain tab characters, this is a good qualifier to use. It will be also more reliable when you import in Excel. If you need to process the field data that may contain quotes, you need prepare correctly the string data and can use a JavaScript library like this: https://github.com/uselesscode/ucsv

• Questions about serial port read and write at the same time

  Hi I create a user interface for the communication serial port, where there are essentially 2 front panels, where the user enters commands one and the other where the prints of UART is delivered. I thought initially using a state machine but the reading and writing may be independent sometimes and so I can't rely on States. I searched a bit on the forum and he left me even more confused. Help, please.

  (1) in a thread that sessions visa duplicated has been used for writing and reading at the same time, is it recommendable? How will this affect performance?

  (2) essentially when the vi is reading data are it must constantly view as well, however, someone said that it takes too much memory to use shift registers, so how do I go about this? If using a State in queue after the loop of reading it affects the playback loop and be sequential?

  In addition anyway is to move the cursor to the latest data from the indicator

  (3) for the control of the user input, assumes that the user has entered an order in the control and press ENTER, then writing visa is launched, but if it comes in another string and press enter then write must be called again... is - it possible? will detect the previous commands in the control of compensation?

  (4) according to my understand the expectation for the event do not monopolize resources and writing can go in parallel, am I right?

  Thank you. I have attached a very basic vi which took me to the point, but I want to make it more robust. Please help especially in the part of the user interface.

  su_a,

  (1) you can have only one session to a port. Several UART can handle full duplex so performance is not affected.  At flow rates of high data and large amounts of data, buffering and latencies of BONE can become a problem.

  (2) who told you that shift registers using too much memory? Shift registers are usually the best way to transfer data from one iteration to another. String concatenation inside a loop (registry to offset or not) causes the chain to develop and may require re-allocation of memory.  Your VI never clears the string so its cold length become very large.

  Generally, you do not have an active cursor on an indicator.  If you want to always display the most recently received characters and turn on the vertical scroll bar use a property node to keep scrolls to the bottom.  This can be annoying for users if they attempt to manually move the scroll bar and find that the program continues to move it back automatically.

  (3) if the user has changed the value in the chain of command, when he hits enter the modified value event fires.  Simply strike brace does not change the value and does not trigger the event.  Not control need to be erased, but the value that he has to change.  If you want to send the same command again, have a button send a command may be a better choice.

  (4) write is a case of the event.  It is not in parallel with anything.  The structure of the event do not monopolize resources.  The other loop will run while it waits.

  The event loop will not stop when you press the STOP button. Probably it wll take two command: change events of value after JUDGMENT before any loop stops.  Replace the Timeout event (which never expires) with a STOP: value change event and a real wire of this judgment to the Terminal endpoint.  Remove the local variable.  Make mechanical locking when released.

• Write in the text file on request

  Hello

  I've been struggling with the "write to text file" in the part of the attached .vi button

  I want to be able to say my program when I press on the Boolean key it should collect 1 sample point only from the mean.vi - now that I managed to do a Boolean-button that starts the collection of data and then I have to press the button again when I 'think' now, I collected a data point using the structure of the case.

  Can someone help me to collect the data a not that when I press the Boolean?

• Reading single line of the text file

  I want to print a single line instead of the file around so I read that I need to store the contents of the file into an array and then get the index of the line. Problem is that I couldn't find any information on how to do it. Can someone give me a shot. Thanks in advance.

  This isn't a problem with encoding. You just need to do a little extra accounting and adjust start and end indices to remove these characters. To treat the "\r\n" of line termination style, you can maintain a flag (initially false) to indicate that the previous line ended with a \r; If a line begins with \n, it should be treated as the end of a line (empty) if the flag is true (in which case it should be ignored).

  If you want to extract all lines (not just the first), then it may be easier to do this accounting while avoiding a separate function. Something like this (untested):

  // read the file into a byte array 'data'; then:
  Vector lines = new Vector();
  boolean endCR = false;
  int start = 0;
  for (i = start; i < data.length; ++i) {
    if (data[i] = 0xD) {
      lines.addElement(new String(data, start, i - start));
      endCR = true;
      start = i + 1;
    } else if (data[i] = 0xA) {
      if (endCR && i == start) {
        start++;
        endCR = false;
      } else {
        lines.addElement(new String(data, start, i - start));
        start = i + 1;
      }
      endCR = false;
    }
  }
  String[] results = new String[lines.size()];
  lines.copyInto(results);
