  1. Given a parent node, using Forward Browse should give you a list of child nodes, including their node ID: https://www.ni.com/docs/en-US/bundle/labview-opc-ua-toolkit-api-ref/page/opcuavis/opcua_forward_browse.html
  2. I just went through the examples and everything appears to be working. Edit: Running on Windows 11, using LabVIEW 2019 (32-bit) As someone who is familiar with your SQLite library, it feels very familiar Thanks for sharing!
  3. Welcome to the forums! Yes this is exactly how the good old perpetual license works. Even without SSP the license is valid indefinitely. At my work we also stayed with LabVIEW 2019 for our codebase. The old licenses are still valid and haven’t been renewed. We have an additional subscription license for support reasons, though.
  4. A couple of ideas: Include a license file that clearly explains what they can and cannot do (e.g., no distribution, no use without a valid license, 30 day trial period, etc.) Use a hardware dongle to prevent copies (you can just encrypt the executable, which can then only be started when the dongle is present. No programming required.) If the application is not licensed (e.g., during a 30 day trial period Automatically shutdown the application after 30 minutes Limit the number of data points they can collect (e.g., limit file size to 1 Mib or 100k samples) Turn off certain features (e.g., limit the types of reports that can be produced) Of course, it depends on what value the application represents and how "useful" it is outside your partnership. At some point, however, you will have to trust them enough to not misuse your software outside what is being agreed. If you don't trust them enough to uphold such an agreement, it is probably better not to go into a partnership...
  5. Yes this happens sometimes. It typically fixes itself after reloading a few times. To be fair, it never happened when actively browsing or editing pages. For me it mostly happens in the morning when I access it for the first time. And it manifests as a DNS lookup error.
  6. I'm not familiar with FPGAs so this might not work, but there is a Timed Loop in LabVIEW: https://www.ni.com/docs/en-US/bundle/labview-api-ref/page/structures/timed-loop.html Edit: Just noticed this note in the article linked above: This might be relevant too: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000P8sWSAS&l=en-US
  7. Yes! It is so much better now. Excellent work!
  8. Unfortunately, it seems that the site upgrade did not fix the spam issue. Are there any new options at your disposal?
  9. Completely agree. I wonder how the number of people with internet access affect the data. In the past the percentage of technology-agnostic people was probably higher on average than nowadays. Especially for niche topics like LabVIEW. It also makes a difference whether you look at global data or just a specific area. For example, interest for LabVIEW in China and USA are somewhat distinct: China USA There are also distinct changes to the slope when Google decides to improve their categorization systems. We may also see a sudden decline for languages with the adoption of AI assistants as most developers don't need to search the internet anymore and instead rely on the answers produced by the Copilot integrated in their IDEs. Maybe this is what's happening to the Python chart?
  10. These statistics can be very misleading as they show interest over time and cannot easily be compared. For example, this is a comparison between LabVIEW (blue), Simulink (yellow), and Node-RED (red): Here is another comparison between PHP (blue), C++ (red), C (yellow), JavaScript (green), and C# (purple): Relatively, each of these languages shows considerable less interest over time and converge towards a similar value. Unfortunately, we can't get the full picture as we do not have earlier data. Otherwise, it would probably show pretty much the same curve as Python does. We are just further along the curve (the hype is over 🙁). For the sake of completeness, this is the graph for Python: While everyone is clearly interested in Python, this doesn't mean that any of the other languages is suddenly going to be obsolete or non-functional. People (and businesses) will always follow the hype train, of course. Though, we should certainly not fall victim to ignorance as clearly the LabVIEW community is not quite as enthusiastic as it used to be. I wonder if we should pitch a Python port of LabVIEW to NI... 😈
  11. Well, yes. There is only so much we can do on the client side. It also appears that some of the bots have recently figured out how to reply to their own posts. It is probably just a matter of time before our notification areas get bombarded...
  12. I have opted to custom uBlock filters for certain keywords and specific user accounts to hide those entries from the activity stream. Not a perfect solution but it makes the page somewhat usable... at least I don't have to see that wall of crap all the time.
  13. I can confirm that LabVIEW 2018 SP1 f4 (32-bit) automatically selects LabVIEW Runtime 2018 SP1 f5 when "automatically select recommended installers" is checked and LabVIEW Runtime 2018 SP1 f5 is installed. Though, it does not ask for the installer source. There used to be SFX installers that were extracted to "C:\National Instruments Downloads". When such an installer was used, the destination folder must not be deleted as it is used as a source location when creating installers in LabVIEW. Perhaps you installed the runtime engine through an old SFX installer and deleted those files at some point?
  14. Spoiler: don't do that on the weekend 😭
