• Need help: loop of pl/sql with UTL_FILE reading and analysis of file text 2

  Hello, I am working on a new project using the UTL_FILE utility in oracle 11 g. and I was wondering if someone could help me with a pl/sql code, I can't understand.
  My goal is to open and then read a Type_de_fichier file1.txt
  copy a specific paragraph of the file1.txt where
  the first word in a specific line in the file1.txt starts with "foo" then when the last word in fichier1.txt ends in 'ZEN'
  write to file2.txt only the analysis section in my where statement.
  I don't know if it's possible, but any guidance will greatly appreciate!
  
  My code example:
  
  CREATE OR REPLACE PROCEDURE my_app2 IS
  Utl_file.file_type inFile;
  OutFile utl_file.file_type;
  buffer VARCHAR2 (30000);
  BEGIN
  -Open a file to read
  InFile: = utl_file.fopen ('TEST_DIR', 'mytst.txt', 'r');
  -Opens a file for writing
  OutFile: = utl_file.fopen ('TEST_DIR', "Out.txt", "w");
  
  -Check the file is open
  IF utl_file.is_open (InFile) THEN
  -lines in the file in loop
  LOOP
  BEGIN
  UTL_FILE.get_line (InFile, buffer);
  -Write to out.txt
  UTL_FILE.put_line (OutFile, buffer, FALSE);
  UTL_FILE.fflush (outfile);
  
  EXCEPTION
  WHEN NO_DATA_FOUND THEN
  EXIT;
  END;
  END LOOP;
  END IF;
  UTL_FILE.fclose (INFILE);
  UTL_FILE.fclose (outfile);
  EXCEPTION
  WHILE OTHERS THEN
  RAISE_APPLICATION_ERROR (-20099, "UTL_FILE Unknown Error");
  END my_app2l;

  Hello

  According to the code should work-

  CREATE OR REPLACE PROCEDURE my_app2 IS
     infile              utl_file.file_type;
     outfile             utl_file.file_type;
     buffer              VARCHAR2(30000);
     b_paragraph_started BOOLEAN := FALSE; -- flag to indicate that required paragraph is started
  BEGIN
     -- open a file to read
     infile := utl_file.fopen('TEST_DIR', 'mytst.txt', 'r');
     -- open a file to write
     outfile := utl_file.fopen('TEST_DIR', 'out.txt', 'w');
  
     -- check file is opened
     IF utl_file.is_open(infile)
     THEN
        -- loop lines in the file
        LOOP
           BEGIN
              utl_file.get_line(infile, buffer);
  
              IF buffer LIKE 'foo%' OR b_paragraph_started
              THEN
                 --write to out.txt
                 utl_file.put_line(outfile, buffer, FALSE);
                 b_paragraph_started := TRUE;
              END IF;
  
              IF buffer LIKE '%ZEN'
              THEN
                 b_paragraph_started := FALSE;
              END IF;
              utl_file.fflush(outfile);
  
           EXCEPTION
              WHEN no_data_found THEN
                 EXIT;
           END;
        END LOOP;
     END IF;
     utl_file.fclose(infile);
     utl_file.fclose(outfile);
  EXCEPTION
     WHEN OTHERS THEN
        raise_application_error(-20099, 'Unknown UTL_FILE Error');
  END my_app2l;
  /
  

  What I've done here is added a new Boolean variable. Loop in each iteration after reading one line, we check if the line starts with "foo". If yes then set the Boolean variable and writing out the startup file until we get a line that ends with "ZEN." That way even if there are several paragraphs in an input file starting with foo and ending with ZEN, then those should get copied to the output file.

  Hope this helps,

• global variable functional to read and write data from and to the parallel loops

  Hello!

  Here is the following situation: I have 3 parallel while loops. I have the fire at the same time. The first loop reads the data from GPIB instruments. Second readers PID powered analog output card (software waveform static timed, cc. Update 3 seconds interval) with DAQmx features. The third argument stores the data in the case of certain conditions to the PDM file.

  I create a functional global variable (FGV) with write and read options containing the measured data (30 double CC in cluster). So when I get a new reading of the GPIB loop, I put the new values in the FGV.

  In parallel loops, I read the FGV when necessary. I know that, I just create a race condition, because when one of the loops reads or writes data in the FGV, no other loops can access, while they hold their race until the loop of winner completed his reading or writing on it.

  In my case, it is not a problem of losing data measured, and also a few short drapes in some loops are okey. (data measured, including the temperature values, used in the loop of PID and the loop to save file, the system also has constants for a significant period, is not a problem if the PID loop reads sometimes on values previous to the FGV in case if he won the race)

  What is a "barbarian way" to make such a code? (later, I want to give a good GUI to my code, so probably I would have to use some sort of event management,...)

  If you recommend something more elegant, please give me some links where I can learn more.

  I started to read and learn to try to expand my little knowledge in LabView, but to me, it seems I can find examples really pro and documents (http://expressionflow.com/2007/10/01/labview-queued-state-machine-architecture/ , http://forums.ni.com/t5/LabVIEW/Community-Nugget-2009-03-13-An-Event-based-messageing-framework/m-p/... ) and really simple, but not in the "middle range". This forum and other sources of NEITHER are really good, but I want to swim in a huge "info-ocean", without guidance...

  I'm after course 1 Core and Core 2, do you know that some free educational material that is based on these? (to say something 'intermediary'...)

  Thank you very much!

  I would use queues instead of a FGV in this particular case.

  A driving force that would provide a signal saying that the data is ready, you can change your FGV readme...  And maybe have an array of clusters to hold values more waiting to be read, etc...  Things get complicated...

  A queue however will do nicely.  You may have an understanding of producer/consumer.  You will need to do maybe not this 3rd loop.  If install you a state machine, which has (among other States): wait for the data (that is where the queue is read), writing to a file, disk PID.

  Your state of inactivity would be the "waiting for data".

  The PID is dependent on the data?  Otherwise it must operate its own, and Yes, you may have a loop for it.  Should run at a different rate from the loop reading data, you may have a different queue or other means for transmitting data to this loop.

  Another tip would be to define the State of PID as the default state and check for new data at regular intervals, thus reducing to 2 loops (producer / consumer).  The new data would be shared on the wires using a shift register.

  There are many tricks.  However, I would not recommend using a basic FGV as your solution.  An Action Engine, would be okay if it includes a mechanism to flag what data has been read (ie index, etc) or once the data has been read, it is deleted from the AE. 
  
  
  There are many ways to implement a solution, you just have to pick the right one that will avoid loosing data.
  

• network variable will not work with VBAI 2010 and windows 7

  Hello

  In fact, I have a problem with 2 EVS-1464 (windows 7) and VBAI 2010.

  I have to use network variables to allow the communication between two electric vehicles, but I can't use it. My network is ok (I can ping between the two facilities) but I can't (t access the network variable.

  I did a test with VBAI2011 EVS / VBAI2010 PC windows XP--> it works. (but I don't want to use VBAI 2011).

  You have solutions to solve my problem?

  Hello

  Here are several documents that might be useful for you:

  Using the LabVIEW shared Variable

  Troubleshooting network-published static Variables

  How can I use shared Variables to transfer data from Vision Builder for Automated Inspection (VBAI)...

  You can also try something. To do this, you must go to the EXE VBAI here:

  For 32-bit machines:
  C:\Program NIUninstaller Instruments\Vision 20XX\ VBAI

  For 64-bit machines:
  C:\Program Files (x 86) \National Instruments\Vision VBAI 20XX\

  Right-click on "Vision Builder.exe", and then select Properties.  Make sure "run this program as an administrator" is checked.

  Click OK, and then try to rerun VBAI. You may need to redeploy the variables in the variable Manager until they work properly.

• Series read the analysis of the data works fine, but the polarity and point decimal placement does not

  I'm new to labview and work on a project that accepts the biotic data. I have read the information and analysis data correctly but when I try to set up the number the polarity and decimal pt do not seem to be correct. When the polarity is negative, a 1, the number that came out is positive. I have posted before and was invited to use the concatenation and the power of 10 and I wonder if it's okay. Should I be looking for the 1 (negative bit) and negate the number at the end before the release?

  I have another question: how to accept a number between the touch screen and just write this number in an output file? I searched in the help and online but found no example.

  Any help would be appreciated.

  I have included my vi.

  Thank you

  I'm sorry, I apologize. I thought since it was a new problem to a new position. I've corrected the problems mentioned in this post me. Oh and when I created the project/vi I created it as a touch panel.

  Thanks again.

• Seen Truble reading and echoing using PHP in HTML. Variable scope problem possible?

  Hey guys,.

  Thanks for your help always well informed! Today, I work with the text to a text file in a table HTML with PHP. I can't get the data to display correctly, I think it has something to do with the scope of variables, but I'm not sure. Here's the code I'm struggeling with that:

  <table width="357" border="1" cellspacing="0" cellpadding="0">
    <tr>
      <td width="165">Pizza 1</td>

    </tr>
    <tr>
      <td>Drink 1</td>
      <td><? echo $price['2']; ?></td>
    </tr>
  </table>
  

  In the above PHP (not shown), the $price array is properly filled (I tested in echoing every bit line-by-line), but at the moment where we enter the HTML code, it seems that the table is empty or is not love how I am the appellant. Made in the scope of a PHP variable with the closing end '? ">" tag? Am I missing something? Below is the full code:

• Acrobat 9 Std - Comments-> "enable for commenting and analysis in Reader" option missing

  Hello

  We bought a copy of Adobe Acrobat 9 Standard and must enable the comments in the reader for the PDF files that we create in Acrobat.  The option "enable for commenting and analysis in Reader" seems to be missing in the menu 'comments', even if all the videos/tutorials insist it's there.

  I have not yet found any discussions about this and google search for the lack of option + 'lack' with other things.  Nothing not associated with came.

  Any ideas on what we could try?  Or why it is happening?

  Thank you!

  I don't think that Standard has this option. Acrobat Pro does.

• simultaneous reading and writing on a PDM file

  I found similar discussions on here, but none that satisfied my problem. I'm running several loops within a vi, which writes data in a permanently .tdms file. Another loop to finish its task from the start in a test, and I want to transition this loop so that it accesses the file writing and started writing on a network. It also enables me to check that the data is being stored in the file and that it is corrupt.

  I started with just the basics, but when I pass the second loop to read the file that is is always written off mistakes, saying that she met at the end of the file. It does if I put the count 1, -1 or anything in between. It illuminates, however, the end of the file output.

  I have the entry in the file tdms on PDM read wired to a local variable, just as I do writing PDM, they all have both read the same thing and I get an iterations of a data value of the reading, so, apparently, file access is no problem. And I have to someone who cringed to local variables, ensure that reading and writing are not activated until the local variable is updated.

  Try to set the "group name" entry on «TDMS read» If you write more than one group, you can use "View the contents of the DDHN" in order to get a list of groups.

• At wich moment a RT controller deploys network Variables?

  Hi all

  I want to know when the shared variables are accessible on a RT PXI controller?

  During the system startup PXI to my request for RT (defined as auto-start) first wants to write the default values for variables.

  Here, I get the error:-1950679035

  This means that the variable is not deployed jet.

  I understand that it takes more of 5 seconds until the variables are really ready to read or write.

  For the moment, I use a work around:

  A network variable 'RT_System_Ready' is played repeatedly until the error has disappeared. This loop takes more than 5seconds.

  After the loop starts the main application and I no longer get the error...

  I think the boot sequence for the RT controller should only start the user application when all libraries are deployed and variables are accessible.

  Greetings,

  Henning

  Hey, Henning.

  No, the bootsequence cares variables, drivers or anything else to be ready, that is used in the application.

  Interrogation of a flag or until the error is gone or waiting for a - and - time is the only way to get that everythings ready!

• DAQ read and write synchronization

  I would like to acquire the data permanently (I) and sometimes write data (AO).

  Currently I have a Subvi permanently this bed to 125kHz. The data is passed to a queue. Another Subvi accepts a user input and provides output tension affecting playback. I traced reading and voltage on a chart. I noticed that over time, the input and output lose alignment. Initially, it is +/-10 ms and then past at 100 + ms - as the control voltage above reading expected by 100 m I switch the control voltage to the Subvi acquisition via a global variable and insert it into a table with playback.

  I am sure that is not the way to do it, but I can't see how trigger can help me here, given that the reading should be continuous. I just need to align the output to the input of my land.

  I solved the task:

  I put a VI "get the date and time" in a structure to deal with the writing of data acquisition. Then, I used the wave function of build and wired an array of unique value (the value of the AO) with the time stamp (to). So instead of using a waveform graph, I used a XY Chart and traced this waveform, but also the waveform of analog input (combined in a table). So if I send a voltage pulse at time t = 100 ms, I see an increase at t = 100 +/-1 m higher, I see the rise at t = 100 + dt ms (dt ~ 10 to 100), because the data was drawn from the buffer too slowly.

  Since I am acquiring data at all times, regardless of the result, triggering is not really useful here.

• 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.

• Sharing network Variable not in Distributed System Manager

  I have experience with LocalHost.   I have 2 computers A, B.  A, I can read a created/static SNV of B.  However, I need to use a SNV on A to A (I don't know why, I inherited this project and it is not at all commented).  So I create and I see it on my drive D:\\.  However, when I go to NI DIstributed System Manager, there are no library under localhost.  So I write in a VI and call it in another, and I get "DataSocketRead in VI" with the code 56.  Don't know why I can't have it is the Manager.

  I have attached ahev the library in case something wrong here.

  Have you deployed and right click the shared variable library?

  If it's an executable in the bulder properties you should check to deploy shared variables.

• network variables

  Greetings,

  I wrote an application that uses c# VS2005 and Measurement Studio 8.5 to control a test Chamber.

  I would like to monitor some settings on a network or the Internet with network variables

  on a remote computer. I have to install Measurement Studio on the remote computer for this

  to work? Or just install some assemblies with a msi installation file?

  Thank you

  SThompson.

  Hi SThompson,

  As the network variables are not a component of measurement studio, you won't have to have it installed on the remote computer unless you plan to debug and recompile an application developed in Measurement Studio.  To deploy the network variables, simply enter the correct merge your installer module:

  Once you create the Setup project, simply add the MStudioNetworkVariable.2005.msm merge module located in the program directory Files\Fichiers communs\Merge Modules for the project. Add this merge module also adds necessary additional dependencies. This step is necessary in order to collect and deploy all the dll and files for the underlying network variable.
