LabVIEW and WCF Web Service


Recommended Posts

Hi Everyone,

I'm using LabVIEW 2011 SP1 and am trying to use the "Import Web Service" to consume a WCF web service. I can connect to the service no problems, but when it comes to the window that lists the methods to import, there seems to be no methods available (even though I know there is).

I've read on NI forums back in 2009 that WCF is not supported by the Import Web Service tool because it was written using .NET framework 3.0 (or prior), however, I'm using .NET framework 4.0. I would have hoped that NI would have updated this from 2-3 years ago.

Does anybody know why the methods are missing? I know I can use a .NET dll, but that will take some more time...

I believe the web service import tool still does not support WCF. A search on the NI forums turns up some alternate approaches, for example these threads:

Thanks for your help Ned.

It looks like a reasonable alternative is to create a proxy class or proxy service. I'm a little ignorant when it comes to .NET. Does anybody have any examples on how to create a proxy service, but more importantly any examples on importing the proxy service into LabVIEW? Does it still use the Import Web Service tool?

      I am just starting on trying to be able to use Python code from a LabVIEW application (mostly for some image analysis stuff).  This is for a large project where some programmers are more comfortable developing in Python than LabVIEW.  I have not done any Python before, and their seem to be a bewildering array of options; many IDE's, Libraries, and Python-LabVIEW connectors.  
      So I was wondering if people who have been using Python with LabVIEW can give their experiences and describe what set of technologies they use.

      I have installed Labview 2020 on Dedian Buster using the rpm to deb conversion method via alien. Due to Architecture mismatch i deleted the *i386.rpm files before conversion.
      My Problem is that after creating a project at "Build Specification"-> "rigth click" i am only able to select "Source Distribution". Application does not show up as an option. 
      I will be grateful for any suggestions.
      Thank you in advance.

      VIPM.io now allows you to post LabVIEW Resources, Ideas, and Tools. For example, you could post a link to a video tutorial or blog article about a package. You can also post ideas, like feature requests or new tools. Best of all, package developers are notified when you post your ideas and resources, and you can comment and discuss posts with the community. Take a look at this video to learn more: https://www.vipm.io/posts/664960df-f111-4e13-989a-24be8207182d/
