• How can I activate LabVIEW web publishing by program tool.

  Dear Experts,

  I'm new with LabVIEW web Publishing; I'm using LabVIEW 8.6 Versions. Anyone help how can I activate the LabVIEW web publishing tool progremmatically.

  I know how to turn the web publishing tool in manually.

  Thanks in advance.

  Your question is not clear at all. What exactly do you do? Also, what have you tried so far?

• LabVIEW Web server on iphone

  It is possible, without using a data dashboard, to see and/or control a front panel LabVIEW on an iPhone using LabVIEW Web Server?

  You probably don't want to have just a VI appear on your iPhone, the way he looks at your computer anyway because the screws are not really designed for a mobile platform. Like, for example the buttons may be too small to press with fingers on such a small screen.

  What you need to do is to write a web page with HTML, Javascript, CSS (or any other tools that you can use for a web page) and have your web service of LabVIEW send data to the web page and the web page send data to the web service. Take a look at these tutorials for more information on how to do it: https://decibel.ni.com/content/docs/DOC-41151

  For that it works well on your iPhone, you just need to design the web page in a way so that is adapting to the screens more small and always beautiful appearance. An easy way to do this is by using bootstrap: http://getbootstrap.com/

• LabVIEW Web Services 7: how to disable

  This summer, we had an external team of Cyber Security come and do an audit of security on our network.

  They found many 'open ports' on our Windows hosts, that is to say the PC was "listening on port 3085'.

  This was reported as a security flaw.

  Most of our PC is still running XP, and many have versions of Labview before Labview 8.6.

  For PCs, if, in a browser, you mention http://: 3580, you get a page that says that the service you specified does not exist.

  I would like to close this port in order to reduce our number of items with safety indicator. We do not publish the web pages of these legacy systems.

  I tried to disable the items via the tools options, but nothing helped.  How can I disable the web services in older versions of Labview?

  Thank you

  Thanks for the tip!  I did a search on this (NI Service Locator) and Yes, he has provided some good info & links.

  One document states:

  Locator Service NI Labview 2010 has benn renamed System Web Server.

  This little helps a lot.  I had been looking on "' Web Server / Services '."

  I turned off NI Service Locator by going to control panel > administrative tools > NI Service Locator.

  Now, when I try http://: 3580 in a browser, I get Oops!  Chrome could not connect to...

  Security hole went!  Hooray!

  Disadvantage: Finder example Labview and Labview help no longer have full functionality.  other programs?  I'll have to find.

  NOR does not recommend turning off OR Service Locator, cannot guarantee the functionality of the software OR if you do.

  Just thought that I would understand that.

  Once again, thank you for the tip.  That's what I needed to know.

• System LabVIEW Web API - unexpected results Service folder

  http://zone.NI.com/DevZone/CDA/EPD/p/ID/6466

  http://www.NI.com/white-paper/11820/en

  The aforementioned white paper explains how I should be able to use the referenced example of API and the "fws/dirlist'"Mapping of URL"to get information on a set of files in a remote directory (in my case on a cRIO).  Using the example of the VI "Directory list" tab, I can actually get this list of files in the specified directory of cRIO. If no option under 'options dirlist' is checked, then the internal POST vi that does the actual work is called with these arguments:

  URL = http://192.168.84.198:3580/AAR/dirlist

  data = Param1 labview = / c / / data / arc_tandh_scissor_lift / & Param2 = XML & Param3 =
  and this is the response that is returned:

  
  
  
  
  
  
  
  
  
  
  
  

  Turn on the "Show details" option causes the POST vi to be called with these arguments:

  http://192.168.84.198:3580/AAR/dirlist

  Param1 = labview / c / / data / arc_tandh_scissor_lift / & Param2 = XML & Param3 =-a

  but the response that is returned unchanged (same as above, no detail!)

  However, turning on the 'sizes show' option causes POST to be called with these arguments:

  http://192.168.84.198:3580/AAR/dirlist

  Param1 = labview / c / / data / arc_tandh_scissor_lift / & Param2 = XML & Param3 = s

  And the returned answer actually contains information about the size of the files:

  
  
  
  
  
  
  
  
  
  
  
  

  This leads to my questions:

  1. In the 'dirlist' '-a ' option broken?
  2. How peux-I, using this API, the dates of creation/editing file for files in remote directory?

  Never mind. I found the problem.  The 'List.vi of the single remote directory"included as part of the example of the API has a small bug in there.

  The '-a ' constant circled below in orange must really be "-a"(il doit exister un espace de fin après le «a»). "" You can see sort from behind the other constants.

  

  After you add the missing space and re - run the VI, I can get this information from the remote directory:

• Implement the json JWT with labview web token

  I need to implement of JWT authentication with labview, how can it be done?

  I'm not aware of an existing library of JWT for LabVIEW. You can see the site of JWT to the creation and analysis of JWT requires:

  JSON encoder / decoder

  base64 encode / decode

  and a signature / encryption method (commonly built HMACSHA256 depends on the Oracle application)

  JSON encoding and decoding is available for LabVIEW 2013: https://zone.ni.com/reference/en-XX/help/371361K-01/glang/flat_unflat_string/

  The other two are not available of NEITHER, but have implementations in the LabVIEW community:

  Base64:

  https://decibel.NI.com/content/docs/doc-5544

  https://decibel.NI.com/content/docs/doc-23233

  Signature:

  If unfortunately JWT support is not provided by default, but all the necessary parts to the realization that he should be here.

• I need to control a LabVIEW web browser

  I have a customer who wants an application that performs the following operations:

  1. Requires the operator to enter a serial number (SN) of the product under test.
     • It's over
  2. Search a database to confirm that the SN has passed all the necessary tests.
     • It's over
  3. Open the portal of internet explore or control the portal since in LabVIEW.
     • It's over, I can bear two ways, either use a batch file to open the windows Explorer or use SHDocVw.IWedBrowser2 to access.
  4. Enter automatically in the SN and SN only in the portal.
     • It is where I am lost
  5. After 90 seconds, close the window and display a timeout.
     • It's over

  This program is 85% completed, but I am quite lost on this. Can someone give me some advice?

  Maybe he could help you to find answers faster

• by using labview co-simulation, how to control the PWM market factor in multisim

  I am new to the use of Multisim with LabVIEW using co-simulation. I would like to ask if there is a PWM component in Multisim, which can have its cycle have to be controlled using LabVIEW? I have an algorithm in LabVIEW that returns the duty cycle values between 0 and 1, representing the percentage of duty cycle.

  How can I control the PWM market factor in Multisim using LabVIEW co-simulation?

  Thank you very much

• How the pressure transducer Validyne system-> Validyne CD280-Dual-> SCB - 68-> PCI-6024E-> LABVIEW works and how we can calibrate the pressure sensor?

  Hello

  I am completely new to LABVIEW software.

  I learn a LABVIEW code existing my pressure (attached) acquisition system which has the path of data as follows: pressure transducer Validyne--> Validyne CD280 - Dual--> SCB - 68--> PCI - 6024E--> LABVIEW and I have a few question:

  1. How does the complete system of the transducer to the LABVIEW work? That is, if we apply the pressure of the transducer, it will change the resistance of the probe then...?

  2. How can I find the equation that expresses the relationship between the pressure and the tension to the keys of the Validyne double-CD280 in the LABVIEW?

  3. If I want to do the probe calibration, what are steps?

  Thank you

• The Web Service of LabVIEW error on restores model ESP

  Hello

  I was hoping that people would be able to help with the following problem:

  I'm currently on the Page Embedded Server (ESP), functionality of the LabVIEW webservices script and keep receiveing an error when you try to view a page.

  I think I put in place the Manager HTTP queries properly - buffered stream with headers

  The correct model is located and used as the page reaches the insertion point variable esp.

  I find that the AddressBook example works fine, unless I try and add an additional variable to the model, then the same error occurs.

  I have attached a sample project which shows the same behavior, and the error is less.

  Tested on LabVIEW 2014 (14.0.1 SP1) 32-bit on 64-bit Windows 7.

  See you soon

  Hi John_Neutron,

  I worked on your code today and we managed to reproduce and to fix the error you saw.

  The Web service name ESP file and rendering the page, but it throws the error because the variable you are trying to set was not properly declared. We managed to make the error go away by changing the file text with Notepad like this ESP.

  --------------------------
  <%
  //This is a server side comment
  // Variables:
  var myvariable;
  //
  %>

  
  

  This is the test pattern

  
  
  It's the body:

  Here's the varaiable

  
  

  Variable: @@myvariable

  
  ---------------------------

  Before, you had / / in front of the variable (making a comment) and you don't have "var" to tell him you have said anything (it's all in the 4th line). Without the appropriate statement, the code generates an error when it is called.

• Web services with customer LV

  A typical approach to web services to access the host (a cRIO incorporated, for example) by using a client running in a browser with JavaScript.  All those put in place a LabVIEW client that calls the web services on the host computer?  How this could be done?

  I have a cRIO with a RESTful web service work and I can access it with my browser.  It works very well.  Now, I want to access the same service using a LabVIEW client... Or I could write my own customer by BT if I new how to register the service with .NET, which I did not.  So, it's a fact that LV can be used to create a web service client.  I'm looking to better understand how it can be done.

  The native TCP VIs can perform HTTP requests and call the methods of Service Web LabVIEW (http://zone.ni.com/devzone/cda/epd/p/id/3153 or http://decibel.ni.com/content/docs/DOC-2230).  Using these screws, you can create a customer of LabVIEW.

  Alternatively, you can use an ActiveX control to the browser with the Navigate2 method to call Web Services:

  

  WSDL files are generally used for Web Services using the SOAP Protocol (Developer Zone Tutorial: LabVIEW using SOAP Web Services call).  I know that it is possible to do the same for a RESTful Web Service (LabVIEW deploy services RESTful web), but I don't have any information on how this is done with a simple Google search in addition, it seems that most of the other public forums has rejected the idea, because you just need to build an HTTP request to call a web method.

• change the frequency for the web service

  I'm under LabVIEW Web Service with an application following the method shown in the example of weather monitor. But my problem here is that I have to keep clicking the Refresh button, then the Web Service can only update the latest data for me. Can someone help me to set an example on how to let the page Web of the Web Service automatically update the value without pressing the Refresh button. Thank you

  First of all your customer needs to support it. If you use the HTTP Client in LabVIEW (GET.vi and so on) you cannot use this method. A normal browser should.

  Take a look at the address book example FindContacts.vi.

  The help topic linked in the previous post, you should get on the way as well. The news are scattered throughout the help file, but it should be possible to understand.

  Basically, there are two output options for a web service VI: Terminal mode as used in the example weather and fashion such Stream used in the example address book VI.

  Use stream mode and build the HTML page yourself, then sends it to the browser with Response.vi write. Somewhere in the top of the HTML page, you need to insert

  If you need to return a string like

  
  
  
  
  
  If your browser supports Refresh,
  this page refreshes in 5 seconds.
