• How to parse the input data of several channels simultaneously via an NI USB-6251 box by use of a single DAQ Assistant?

  I did separate VI for reading signals from several channels on a map of NI USB-6251.  I would like to combine these in a VI VI alone so that they can run that at the same time, however, there is an error if there is more that a single DAQ Assistant in the same--> error-50103 VI was held at DAQmx controls Task.vi:32 (the specified resource is reserved. The operation could not be performed as indicated.)

  All the inputs of channel must then be read in with a single DAQ Assistant, but all of the data on different channels are not separated.  Can save this data in a matrix or otherwise manageable which allow to facilitate the analysis of the data from the separate channel entries?

  I tried to view the data in a file of measures, but then when I tried InPort data, I could all the data I wanted.

  Hi AggieGirl,

  Good afternoon and I hope that your well today.

  First of all, you will not be able to have more than one DAQ Assistant by input analog or analog output task because the device has only one of each. So, you must have a DAQ task to HAVE and AO. (This is not the case for DIO static).

  There is far from split signals using the express VI - signal splitter.

  When you say you saved this file and it does not work, how it did not work? The Express VI - save a file of measures needed to manage multiple waveforms. Can send you your code & explain more about what was not OK on the file?

  

  Thank you

• How to read the QFile data?

  Hi all

  Today I try the code to read the data below, but whenever I get null so may I know how do I get the data from the file?

  readFromFile: -.

  QString ApplicationUI::readFromFile()
  {
      QFile textfile("data/files/text/newfile.txt");
      QString str = "";
      if (textfile.open(QIODevice::ReadOnly | QIODevice::Text)) {
          QTextStream in(&textfile);
          str = in.readAll();
          qDebug() << "Called....." << str;
      }else{
          qDebug() << "Test called...";
      }
      textfile.close();
      return str;
  }
  

  WriteData : -.

  void ApplicationUI::writeFile(QString dataText)
  {
      QDir dir("data/files/text");
      if (dir.exists()) {
          QFile textfile("data/files/text/newfile.txt");
          textfile.open(QIODevice::WriteOnly | QIODevice::Text);
          QTextStream out(&textfile);
          qDebug() << readFromFile();
          out << readFromFile() + "n" + dataText + "\n";
          textfile.close();
          qDebug() << "TextFile exists if called...";
      } else {
          dir.mkpath("data/files/text");
          dir.cd("data/files/text");
          QFile textfile("data/files/text/newfile.txt");
          textfile.open(QIODevice::WriteOnly | QIODevice::Text);
          QTextStream out(&textfile);
          out << dataText + "\n";
          textfile.close();
          qDebug() << "TextFile exists else called...";
      }
  }
  

  Note:- My face is only read problem data another entry works very well.

  It works for me

  void ApplicationUI::textFile(QString dataText)
  {
      QDir dir(QDir::homePath() + "/files/text");
  
      if (!dir.exists()) {
          dir.mkpath(dir.path());
      }
      if (dir.cd(dir.path()))
          qDebug() << "File is readable";
  
      QFile textfile(dir.path() + "/newfile.txt");
      textfile.open(QIODevice::WriteOnly | QIODevice::Text | QIODevice::Append);
      QTextStream out(&textfile);
      out << dataText ;
      textfile.close();
  }
  

  One thing: I noticed that you were trying to ADD data, so I added QIODevice::Append inside open(). I don't think you can use readFromFile() with the < because="" your="" file="" is="" already="" used="" and="" it="" probably="" throws="" an="">

  The analysis of string function takes a "Format string" on top (with the right button of the function and choose Help, which explains all the entries).  In particular, you can say 'Give me two numbers separated by a tab' and the output will be two numbers (whole or floating, depending on the chosen format).  In particular, %d\t%d specifies a decimal integer, , whole decimal.

• How to read the tag bluetooth data in labview 2015 running on Windows 10

  Hi all

  I have a Development Board Nordic semiconductor nr51. This card is programmed as a tag bluetooth which simply announces his address with 16 bits of data appended to the end.

  My laptop came with loan materials smart bluetooth. I installed an app interactor lighthouse to bluetooth on my laptop and the software is able to detect the tag as if shown on the image below.

  

  I wanted to write a LabVIEW program that will simply be careful bluetooth headlights and notify me in my computer every time a lighthouse with the specified address is detected. This mobile application below is provided by the manufactuerer of the Board of Directors and I wanted to develop a LabVIEW program something similar to what will read the given data and extract values.

  

  Somehow, all the sample applications provided data only shows how to read and write in a connected bletooth device but not analysis for tags. I also tried using the Bluetooth ' discover ' and it does not detect the bluetooth beacons.

  Could someone provide me with the necessary information or example program for detecting / reading of tags bluetooth in LabVIEW 2015 running on Windows 10?

  Do I need to install a third-party software to read data from bluetooth?

  Bluetooth in LabVIEW function nodes using the Winsock interface to access bluetooth resources. This works very well for Bluetooth 2.0 devices but not Bluetooth 4.0 devices WHEAT aka. Microsoft has created a completely different interface for these resources API as the model of overall service for WHEAT devices has radically changed.

  The API to use WHEAT devices is the API of the GATT (generic attribute profile) in Windows. There is supposedly a .net interface available that you can try to use (Windows.Devices.Bluetooth.GenericAttributeProfile). The WinAPI to lower level (https://msdn.microsoft.com/en-us/library/windows/hardware/hh450825(v=vs.85).aspx) is a C DLL API and does not lend at all to be called directly by the LabVIEW call library node, since some of the parameters of the function are quite complicated and you need to also access the SetupDI APIs to enumerate resources WHEAT and even harder to function parameters. In order to access this low-level API to write an intermediate DLL which results in low level API C a more acceptable API for LabVIEW.

  Another possible problem is that Windows don't at least in Windows 8 not allows devices to pair per program. Microsoft wanted to force developers in the use of the "inbox" experience, which means that all users must go through Microsoft provided service pairing, instead of each request for implementation of his own matching technique.

  Did you watch net.rim.device.api.system.USBPort?

  That's what the doc says:

  Provides access to the USB port of the device.

  Avoid using this class in applications, as it is not portable. On the contrary, if you need to access the USB port, use factory CLDC Connector to serve a connection.

• How to read the data with different XML schemas within the unique connection?

  • I have Oracle database 11g
  • I access it via JDBC: Slim, version 11.2.0.3, same as xdb.
  • I have several tables, each has an XMLType column, all based on patterns.
  • There are three XML schemas different registered in the DB
  • Maybe I need to read the XML data in multiple tables.
  • If all the XMLTypes have the same XML schema, there is no problem,
  • If patterns are different, the second reading will throw BindXMLException.
  • If I reset the connection between the readings of the XMLType column with different schemas, it works.

  The question is: How can I configure the driver, or the connection to be able to read the data with different XML schemas without resetting the connection (which is expensive).

  Code to get data from XMLType is the implementation of case study:

   1   ResultSet resultSet = statement.executeQuery( sql ) ; 
   2   String result = null ; 
   3    while(resultSet.next()) { 
   4   SQLXML sqlxml = resultSet.getSQLXML(1) ; 
   5   result = sqlxml.getString() ; 
   6   sqlxml.free(); 
   7   } 
   8   resultSet.close(); 
   9    return result ; 
  

  It turns out, that I needed to serialize the XML on the server and read it as BLOB. Like this:

   1    final Statement statement = connection.createStatement() ;  2    final String sql = String.format("select xmlserialize(content xml_content_column as blob encoding 'UTF-8') from %s where key='%s'", table, key ) ;  3   ResultSet resultSet = statement.executeQuery( sql ) ;  4   String result = null ;  5    while(resultSet.next()) {  6   Blob blob = resultSet.getBlob( 1 );  7   InputStream inputStream = blob.getBinaryStream();  8   result = new Scanner( inputStream ).useDelimiter( "\\A" ).next();  9   inputStream.close(); 10   blob.free(); 11   } 12   resultSet.close(); 13   statement.close(); 14  15   System.out.println( result ); 16    return result ; 17
  

  Then it works. Still, can't get it work with XMLType in resultset. On the customer XML unwrapping explodes trying to pass to another XML schema. JDBC/XDB problem?

• How to restrict the scope of the EU change when the input data are not available?

  Hi Experts,
  
  I have a user enter-able (EU) field in the Section. When the tag input XML contains data for this field, then the value must print in this area and it is not editable.
  If the input data are not available only that one time that the field of the EU must be editable.
  
  Any thoughts?
  
  I tried like below,
  
  Domain name creation: UE_CompName
  Length: 15
  Type: alphanumeric
  Rule: XDD
  Source name:! Transaction/Compname
  under PreEdit,.
  module: DALW32
  Procedure: procedure of desired
  Information: CALL ("UE_CHECK")
  
  like that, I've updated in the field properties.
  
  Content of UE_CHECK DAL below,
  
  CurrFieldName = Fieldname()
  CurrFieldData = @("CurrFieldName")
  
  IF CurrFieldData! = « »
  SetProtect ("CurrFieldName")
  END
  But it does not work... Pls help me to do this...

  I assume that the 'mapping' occurs during a batch operation (Gendata) through any rule the XDD defined for this field. In the batch, pre and Post Edit calculations do not. This feature is related to the WIP/entry. What you can do is to add a level section - PostImageDAL rule to call your script and protect your land once it was located batch of your operation.

  In FAP that contains that field, add the PostImageDAL rule in the property of the rules in the Section box. In the data box, do call your script.
  Your script is a bit wrong, it seems you were trying to get the 'current' domain name and then check the value of fields. Drop the part and simply name your field in the string in quotation marks in the @ () function and the SetProtect.

• How to read the application note on PC pad notes?

  I have a backup of notes (file "note pad.dat"), taken on a Palm T3 I want to read.

  I know how to read information in the notebook, address book,... files because the information is in the text (even if the file contains binary information).

  But in the notepad.dat file, there is only binary data (because the notes are images ).

  Anyone know the format of the images and how extracted from the notepad.dat file?

  Is there a tool to read the file to see the images?

  Thank you.

  Hello!

  Notepad.dat is a Table of Allocation of the data file that can be displayed only "regularity" of the Palm Desktop application for PC.  Install Palm Desktop version 4 of your Tungsten T3 CD and do the same user.  You will then need to this notepad.dat file in the directory of your user name, traditionally found in the registry:

  C:/Program Files / palmone / "username" / Notepad.

  Once your there, delete the existing notepad.dat there and then copy/paste your sustained here notepad.dat.  Then, open the Palm Desktop application to see if the notebook entries are here.

  To emphasize the point that current versions of Palm Desktop on our website have not the ability to view the notebook entries hence the need to use one on your Tungsten T3 CD to a PC.  Hope this works for you.
