  Hello Abul,

  You can use reading worksheet function to read the data from the worksheet. You may need to start by importing current data to a CSV file before using this feature as LabVIEW cannot read Excel files.

  From there, you can send the picture in a chart in waveform on the front panel.

  To summarize each variable, you must select a column with the function array index and use the function of elements of array add to get the sum.

  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.

• How to read the data in a device connected to the usb port

  Is there a class or object, or the piece of code in Java that is comparable to the PDQComm32.ocx and the mscomm32.ocx used in VB6? I need to know how to read the data of a device plugged into the usb port of the BBerry. Is it possible to use the BB to read data from a device via a usb cable?

  I'm new in Java and I'm looking for the opportunity to write a project to read the data in a device with this program that can turn on a BB instead of on a pc.

  Thank you

  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 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.

• How to read the status of User1 DIP-switch with a cRIO FPGA chassis?

  How to read the State of the DIP switches on a FPGA cRio chassis?

  I work with a cRIO 9022... My idea is to put the system in "service" mode with USER1 switch to IT and communicate with the FPGA via the FPGA - GUI (VI) on the host computer instead via the RT module that is used in normal conditions.

  Any ideas? Unfortunately, I don't have an unused channel on the left... .and (as I know) cannot use the interface RS232 of FPGA.

  Many thanks in advance,

  Luke

  Hi, this is the correct information. You cannot read the FPGA of DIP-switch status. The only thing you could do is to use the function of Reading Switch.vi located under the range of functions-> real-> utilities RT time

  It's how you probably know side host RT and not the FPGA.

  If you have VI Analyzer installed, you can load the configuration file and look at the section select the Tests. There is a test for the maximum size of front under front-> User Interface. The default value is the resolution of the current monitor of the PC (including multiple monitors). You can change to the desired option.
