  1. Hi All, Can anybody shed some light on some strange behaviour I am seeing when deploying an executable with Web Services and Public Content. I have an HTML page that gets served up as part of my application. My LabVIEW application interacts with a browser via Web Services. Everything runs (mostly) fine, I can browse to localhost/ws/index.html and I get my web page. However, I would have expected that HTML (and JavaScript etc) would remain on disk in source form so I could edit it after the LabVIEW application has been built, but this does not appear to be the case. Changes I ma
  2. ShaunR's recent topic on Security reminded me of a situation we explored in the summer and need to revisit at some point. We were looking for a method to protect the communication with a cRIO. The situation is that we need to communicate between a cRIO and a host on an unsecured network (manufacturing environment.) We concluded that we needed some form of encryption as well as a standard login mechanism but identified that having a single symmetrical key would not provide enough protection (for various reasons and specific use cases.) Therefore, we looked into SSL and LabVIEW Web Servi
  3. Hello I have a problem with http VI’s and external web services (RESTful) and I’m using LabVIEW 2013. In NetBeans I create a project with a GET web service from a table in MySQL, so I use http VI’s for accessing the service (blog diagram .png), receiving the information in JSON (front panel.png) and took the information I needed (in this case the “slActualValue†value). I have a program that inserts new values in the database and in chrome the service works fine but if a want to do the Vi in a while loop to update or receive new values, the the next JSON data form the web
  4. Hi guys, just wondering if it is possible to publish a web service with a control and simulation loop in the vi. I have a simulation loop and an output of an array and matrix of data from a signal, yet i can't seem to be able to deploy the vi at all. It will build but not deploy. Any help or advice would be most appreciated. Thanks
  5. Hi All, Here in the UK we have just completed our annual NIDays conference where we were lucky enough to get the first public preview of something R&D have been working on. There is an app for iPad and Android tablets to allow you to monitor shared variables and web services on a configurable graphical display. This is currently in internal beta but you can see the preview by going to the National Instruments channel on IET.tv and looking for the future technologies in LabVIEW video.
