  1. I'd like to see some probes just to make sure those are the actual values going in, since it might be what you think is going in but isn't. Assuming that is fine I'd check to see if it works on a new file and not one that already exists and has a different data type for that group channel pair. Also the reference is valid obviously, but was it opened as "Open Read-Only"? If this is a subVI I'd just unit test this by writing a quick test that creates a file and writes to the channel. Nothing obvious is wrong with the code you have shown, which makes me think it is an issue somewhere else. Oh and is your timestamp array empty? Or is there an error being generated from that waveform function? I think the TDMS function should just pass the error through but I'd probe it to make sure.
  2. Did you log in with your NI account after the install?
  3. Well for me it would be a bit more complicated since I have Pre/Post Install and Uninstall VIs. And some of those VIs depend on VIs in some of the packages. So install order matters and dependencies would need to be checked so the order is right, and Pre/Post Install things ran in the right order, with the right input for things like Package Name, Install Files, etc. put into the variant input of those VIs. Still possible and adds some complications. Which is why to date I still just install VIPM and let it handle it.
  4. I believe this post by AQ is the one you are referring to.
  5. Yeah sorry for the confusion. I don't have official release process in place for this community stuff and I really should. I did make a newer version of this for the TDMS package and just included it in it because I wanted to make consuming my code easiest for other developers. But with the efforts of VIPM, and GCentral I need to evaluate the best way to share and hold myself to the process to avoid confusion in the future.
  6. I think we're at the point where to better help you need to post the actual VIs. I suspect lots of coding styles that are indicative of beginner LabVIEW programmers and I can't make blanket statements like "Don't do this" without being able to see more of what you are trying to do. Like my initial reaction is that timed loops shouldn't be used except on RT or FPGA platforms. I also see lots of booleans that I would suggest using an event structure for capturing their value change. Maybe putting them all into a single cluster and capturing that value change would be better. Other suggestions are to use a state machine, or queue message handler. This usually has a cluster of stuff to carry between cases and can be thought of as something akin to variables.
  7. Years ago as a proof of concept I made a LabVIEW program that installed packages without needing VIPM installed. As Michael said the files are zips with a specific structure, and spec file defining where the files should be placed, and optional pre/post VIs to run. Obviously VIPM can do more things like track down packages that are dependent from the network, resolve version information, and a bunch of other things. But if you just have a VIPC with all your packages in it that you need to install, it probably wouldn't be too hard to make a LabVIEW program that just installs that.
  8. I've not used LabVIEW 64-bit for anything real, but looking at the package I believe it should be compatible. What error are you seeing exactly?
  9. I have seen a time when I launched VIPM 2020 and nothing happened. So I looked in the task manager and saw VIPM trying to start, and I task killed it, and saw that there is a helper application that I think had the name service in it. I task killed that too. Then relaunching 2020 worked. This might be what you are running into too.
  10. I haven't, and my initial reaction is that I would quit a job like the one you described. The closest I came was when my boss sat me down to show me his 5 year plan for the group since he heard I was planning on quitting soon and he hoped his new road map would inspire me to stick around. I thanked him profusely for showing me his plans, because it meant that I knew I was making the right decision leaving. I quit, he started steering toward an ice burg, then he was fired about a year later. I was contacted by a head hunter saying this job opportunity was a perfect fit for me. I had to inform him I had that job and listed reasons why I wouldn't come back. Someone else that was still there tried getting me to come back, only to realize they were one of the reasons I left. Things have not sounded all that great since.
  11. So there are plenty of improvements I can suggest for readability, but overall I think the code isn't bad. A few comments would help, and I'd prefer less feedback nodes, and instead code that calls it in a loop, but to be fair that might have just been what you did to demo it. I think all that is needed to to try to not use the dynamic data type. It can do unexpected things, and can hide some of what is going on, inside those functions that you need to open the configure dialog for. This can make the code less readable. So I'd get rid of the To Dynamic data, and instead use the Array Subset function on the 2D array of doubles. This should allow you to get just the two columns you want, and write that to the TDMS file. You may have to mess with the decimation, and possibly transpose the 2D array. I can never remember how the functions work, and so I'm often writing test code to see if the columns end up the way I want. This will mean of course that you also use the Array Subset on the 1D array of string which is the channel names. As for the time entry, it looks like it works, but might I suggest a different string format? Here is a post that shows how to use the Format Into String, with the timestamp input, which returns an ISO standard string format. More standard, and if a log is moved from one timezone to the next, it can still be clear when the log was made.
  12. Yeah targeting the upper management likely would result in more sales. But may also result in less engineers willing to use NI and their products, having been force fed the wrong, or less appropriate tool for the job. I worked with a group that had Veristand 2009 forced down from upper management. NI came in with a dazzling presentation and convinced them to change over their dyno control systems to it and the PXI platform. They did without consulting the engineers, and as a result there was a daily battle where I would repeat "Rewrite Veristand" when some trivial task for LabVIEW, couldn't be done in it. Veristand 2009 ended up being somewhat of a flop, and from what I remember nothing ported to 2010 since NI made some major rewrites of it. We eventually got an apology from NI which basically equated to, sorry we gave you the impression this product was more usable than it actually was. Luckily my current boss knows NI and their offerings, but trusts my opinion over theirs. They need to convince me something is a good fit, before they will convince him. They have some new test platforms that directly align with our business (battery test in automotive), and so far I'm unimpressed except when it comes to hardware.
  13. @Aristos Queue, I was part of the private preview event and afterwards there were several comments basically saying "I watched all of this and have no idea what NI is announcing". And multiple requests that NI make it clear what they are trying to announce. I thought maybe the public event would be more clear. Nope, dozens of comments were flying in asking what, if anything was changing as the event went on. After the event ended my favorite comment was "That was a great introduction, but when does the actual event start?". Threads on Reddit, LAVA, and NI all have had various amounts of "What does this mean?" other than a new logo and color scheme. After reading and listening to NI's feedback, only your post made it clear to me what NI was trying to say. So while NI marketing may think they are making it loud and clear, the community has also been pretty loud themselves with their statements that they aren't sure what NI was trying to say.
  14. I had my share of insane objects, but I'd just clear the compile cache, and revert with SCC. I don't ever remember seeing insane objects in the installed LabVIEW functions, but if that happened it would be a bit more of a pain to resolve.
  15. Also around this era was the Web UI Builder which has other elements now seen in NXG.
