  1. Lots of questions here, I will simply point you to vipm.io from when you'll be able to get VIPM related info. There are 4 'levels' of VIPM, free, community, pro and entreprise, see differences here https://www.vipm.io/download/ As far as I know VIPM is not a tool that will let you manage license subscription in your product, for this I think the best starting point is on NI forums : https://forums.ni.com/t5/Developer-Center-Resources/tkb-p/7307 As a side note, I think handling different types of licenses of your product is not an easy task, good luck with that!
  2. Your reply came as I was typing my edit... Thanks
  3. Has anyone been able to make this work on Linux desktop? I use LV 2020 SP1 (therefore 64 bit) on Ubuntu 20 I ran to install libcrypto.so but at the first call of the so "OpenSSL_add_all_digests" I get error 15 "resource not found" and indeed if in the CLFN I put the full libcrypto.so path, the "OpenSSL_add_all_digests" is not in the "function" list edit : I guess the answer is RTFM With help from a co-worker we could make it work on Linux, multiple functions have different names, will post the VI soon.
  4. pour les refs activeX, oui je pense qu'il faut les fermer. Pour les refs de controles, je te renvoie à la présentation de Darren Nattinger : https://forums.ni.com/t5/LabVIEW/Which-references-need-to-be-quot-Closed-quot/m-p/3775021#M1063802 Tu peux lire l'entier du fil... mais c'est un peu long
  5. Also, I think you can find advanced examples if you go to Help > Find examples > vision
  6. I don't have Vision Dev module anymore so I can't send you code, sorry. There are a few things to consider, here, what is your camera (brand, model)? And do you have a fast drive to save on (SSD)? I'm asking this because most probably, the code you wrote is limited by the fact acquisition and saving are done in the same loop. And I doubt that - even with an SSD - your computer would be able to acq+save 100k images per second, even if those images are small in resolution. Also note that saving to TIFF might not be the fastest option. I think you have to go for a slightly more elaborated architecture and use 2 loops, one for acquisition and another one for saving. About 10 years ago I made a system that was acquiring 4k images per second (tiny images, 128*1000 8bit monochrome), it had to work without an SSD not we were limited in the duration of acquisition depending on the RAM, the concept was to fill the RAM for as long as we could, stop the acquisition and save to disk. But the first step for you I guess is to calculate the throughput in Mbytes /s that you'd like to achieve, I'd say 200 Mbytes or lower you culd probably stream to disk untill it's full.
  7. VIs from DSC / user management let you check the user/group of currently connected user and based on that you can decide to do anything you wish, refuse keyboard entry, value change on controls, etc... To be clear, I'm not saying you should use the DSC module, I'm simply saying it could be used also to do that. Now... do you already have a licence for it? If not, just implement your own user management. If yes, not too fast, using it requires to understand how it stores the information about the domain (groups/users) etc.
  8. In the past I used the DSC module from NI, it lets you create groups and users in those groups, then in any VI of your project you can hide front panel elements based on groups. There is a palette with a few VIs to list / change users. Pretty handy, and if you change user during execution, automagically LabVIEW handles the rules that you defined. You can't change changes "rules" during execution. DSC module is Windows only. edit : a runtime is needed for deployed EXEs, I'm pretty sure the runtime is free, at least it was in the past.
  9. hey... wait a minute, does this mean that when a class is loaded on host and on RT target, it will be locked, and we'll be stuck with this limitation untill the end of LabVIEW?
  10. It was very nice to have you as an NI insider participating on LAVA, wish you a lot of fun in your new mission.
  11. I think it's called project provider, there is a special interest group on NI Forums I've never fiddled with this but some have, here's a few other links : - https://forums.ni.com/t5/Developer-Center-Resources/Customize-the-LabVIEW-Project-Explorer-Using-the-Project/ta-p/3532774?profile.language=fr - https://forums.ni.com/t5/LabVIEW-Project-Providers/Project-Providers-Documentation/m-p/3492573#M285 -
  12. That doesn't shock me at all. The activity on LAVA is - and has been for quite some time - very low. Edit : ... in quantity of course
  13. I'm one of those. I'm not sure how young lads do their internet search but if you look-up "labview forum" LAVA is in the top 3
  14. Do you do that? In 15 years I only met one LabVIEW Dev who was in a job where management organised pair programming. I'd like to hear feedback from people who do that 🧐
  15. Is NI sharing public information to support this statement? LAVA might not be a good indicator of LV's user base mood, but I find it hard to be confident/positive about LabVIEW's future - and I'm trying hard because I do love LabVIEW.
  16. I think it’s a pattern at NI, only scratching the surface. lots of products or support for standards are superficial. They exhort us to engineer ambitiously because they don’t.
  17. For that kind of Ui elements property management I use the QControls toolkit (homepage, download link) I've never really looked at the property browser, so I'm not sure if it could help.
  18. Maybe you can still find the openg commander on sourceforge No idea if it supports Linux but I believe it's open source
  19. Yep, I remember when Tim Dehne left NI, rumor I heard at the time was he wanted to become CEO and understood he would never make it, then left. Indeed it took a long time for Dr T to retire. But hey, pretty sure the rumor was not the full story, so many VPs were competing for that.
  20. If I remember well, windows 10 iot was the default option with the industrial computer from Advantech, at least that's what the reseller told me. We ordered one to try (with a return option if it didn't work), we tested for a few days, we were happy. We were only interested in in having something that worked like windows 10, came pre-installed and didn't have all the media/game nonsense that comes on "normal" computers.
  21. I'm pretty sure I read somewhere that he started from the erdosmiller TOML library Edit : I knew :
