  1. @drjdpowell, thanks for all the work you put into this really useful library. I noticed you have some timestamp conversion utilities that the SQLite library uses. I am confused by some behavior I am seeing when converting a string timestamp with a local time offset. Can you look at the attached screenshot of that function? Maybe this is expected behavior and I'm not understanding something. Thanks, Eric
  2. This happened on a virtual machine that only had LabVIEW 2020 installed. VIPM was always configured to mass compile VIs after package installation. If this happened even when packages were being mass compiled, what else is lurking under the hood waiting to be found? I want to assume that had I built an EXE in this state, this problem would have gone away.
  3. I was experiencing a whole host of problems running an application in LabVIEW 2020 (32-bit) dev environment. This function was giving me the wrong output. After an edit and save, the output of the function now appears correct. This is the first time I have ever seen this... 2020-09-11_17-18-49.mp4
  4. The two people who gave this presentation might be able to point you in the right direction.
  5. Oh, you can turn it off.... Well previously I was using the right-click plugin, so I was happy to see it appear as a feature in 2019. When it comes to software, over the years I have adjusted my attitude by telling myself to "expect everything to change all the time". That way I'm not frustrated every time I have to reteach myself something. On the upside, it's probably a good mental exercise to not allow our muscle memory to become burned in. Think of it as cross-training for the brain. 🙂
  6. Now you've got me thinking. I'm so habituated to creating typedefs, events, and registrations for every message. Maybe there's a better way...
  7. I have to be careful what I say here because I haven't explored Messenger Library, but my inclination is to think that I'm going to have to know the type at some point in time whether it be at edit time or at run time. So at what point in time would I rather know it? I just downloaded the package and flagged your YouTube videos to watch.
  8. Tell me about it! I think I've written seven of them so far and every time I create a new one I have to reference my previous modules to help me get the new one working. It's not trivial. For that reason I moved complex logic outside of DCAF to a higher level. DCAF manages I/O like scan engine, serial/modbus instruments, calculated tags. I wrapped DCAF in a subsystem that all other subsystems must use to access I/O. Since DCAF exposes I/O data through NI's CVT, I make sure not to use the CVT elsewhere throughout my application as that would bypass the protections I put in place for wri
  9. That doesn't necessarily have to be true if you're willing to dig in to specifics of existing frameworks even if you haven't spent a lot of time developing with them. For example, Antoine points out that DQMH has good scripting tools. I agree with him, even though I haven't developed a large project with it. DQMH seems like it makes it very easy to create new messages with custom data types. Those are good suggestions to add to the comparison chart! This raises the question of what a framework should be: process startup and management, dependency management, data management, interproce
  10. SMO. I'm guessing Francois will say the same thing since he wrote a large part of it. Several months ago I was comparing three common community frameworks and I had Francois chime in. I attached a screenshot of what we put together with our rankings obscured. If he's ok with me showing it, I'd love to reveal our rough rankings for the categories shown. My superficial summary of each? Actor Framework - you better love having LOTS of classes in your project and opening DO methods to figure out how the code works. JKI SMO - Use this framework and Steven Mercer will castiga
  11. Can you show me how to make LabVIEW crash by doing this? I created and destroyed 1 million DVRs that were cast to integer and cast back to DVR and couldn't get LabVIEW to crash. Attached VI made with LabVIEW 2013. DVR to integer_2013.vi
  12. There's this reference design framework, but as far as I know it doesn't have scripting to create accessor methods. https://github.com/JKISoftware/JKI-State-Machine-Objects
  13. I'm happy to report that the bug seems to have been fixed. I opened the example code I originally posted using 17.0.1f1 (32-bit) and the buggy behavior has gone away.
  14. It might exist in 2015 as well? I realize if we can't make these issues reproducible then it's difficult to report. I'm going back and forth between two projects right now - one uses LV2015 and the other uses LV2017 - so I'm forming opinions about the apparent stability of each. The LV2015 project is YUGE!!! and it's mostly stable as long as I don't right-click on anything in the project Dependencies folder and select 'Why is this item in Dependencies?' which will instantly crash LV. The safer bet is to right-click an item and select 'Find>Callers'. So one of my few gripes with 20
  15. I've been encountering so much strange behavior in the 2017 dev environment that I started taking screenshots of all the weird stuff I was seeing and I finally just gave up. I already mentioned the weird stuff with parallel access DVRs, but I keep getting some non-parallel DVRs where the wire in the DVR in place element structure is just broken for no reason. Reattaching seems to fix it for a while. One screenshot I did keep was an error state that occurred from a class appearing as a duplicate within a Typedefs folder (attached). Don't ask me how that happened. How can a class exist
