Hi @sam836 welcome to the OpenTAP Forum! 1 and 2 are somewhat the same. LabVIEW has an ActiveX interface, so it can be called from C# within the OpenTAP architecture, or compiled as a DLL: [https://zone.ni.com/reference/en-XX/help/371361R-01/lvdialog/build\_net\_db/](https://zone.ni.com/reference/en-XX/help/371361R-01/lvdialog/build_net_db/) [https://forums.ni.com/t5/Example-Program-Drafts/Calling-LabVIEW-VIs-from-Other-Programming-Languages/ta-p/4100347](https://forums.ni.com/t5/Example-Program-Drafts/Calling-LabVIEW-VIs-from-Other-Programming-Languages/ta-p/4100347) We can see the thread here for someone that has tried this, I know a few others have as well: > [@Licensing error using measurement studio classes to create plugins!](https://forum.opentap.io/t/licensing-error-using-measurement-studio-classes-to-create-plugins/276): > > Hello. I’m trying to use NI’s network variable to send some results to labview program. Inside the result listener, I added code like this: //initialize the network variables \_stringWriter = new NetworkVariableBufferedWriter\(StringNetworkVariableLocation); \_stringWriter.Connect(); It showed errors in session log like this: 16:26:01.407 Summary -------- Test plan completed successfully in 3.67 s -------- 16:26:01.419 PyPowerAnalyzer Device PSU closed 16… 1. This is really up to your preference. We have SDK’s in C# and Python, and those are the most common, but like LabVIEW above it is fairly easy to integrate with any other programming language. Can you share a bit more on what it is you are looking for and trying to do? I think this is an interesting topic for many here. --- _[View the full topic](https://forum.opentap.io/t/test-cases-developed-in-labview/653)._
