I have answered my own question by not checking off the "Disconnect unused inline subVIs" checkbox. However, I now have the issue that all the libraries in my Source Distribution now refer to the original paths of included VIs. This is strange as I have preserved the folder hierarchy when releasing the source, and I was under the impression that libraries, projects, etc. were relying on relative paths... There seems to be no way for me to resolve these conflicts, and even if there was, I don't think this is a practical way to handle this type of release. Does any one have any experience with this type of release (and actually tried to use the released source)? Note that the exported project, even though it is riddled with conflicts does let me run the top level VI just fine, as if all this complaining about conflicts was just for show.

I have a large project with many libraries which I am trying to release as a Source Distribution. I am regularly releasing standalone executables of that project without a hitch. However, the source distribution, once I open the top level VI in a copy of the project I place in the source distribution folder, after updating all paths to the new destination, ends up with many broken VIs. Examining the source of the problem, it appears that it is due to many (if not all) VIMs in my project being replaced by VIs with made-up names (random series of characters.vi), and the Assert Type VIMs in those VIs being themselves replaced by similarly randomly named VIs, and broken. I recall having read threads about some sort of incompatibility between VIMs and libraries, but since I did not have any problems with them during development (or application release), I am kind of at a loss as to what to do next... Is there some literature I can read on the dos and don'ts of Source Distribution release and VIMs + libraries? LabVIEW 2021 SP1 64 bits on Windows 10.

Thanks for the clarification.

Can you tell more? The site is pretty terse. Examples of topics discussed in past editions would be useful.

It takes a thief to catch a thief.

Feed an array comprised of non trivial equal numbers (e.g. a 1,000 values of 1.2345) to the Std Deviation and Variance.vi of the Mathematics>>Probability & Statistics palette and look at the standard deviation output using a display format such as that shown below: You will be surprised to see that the standard deviation is non zero and within the range of the precision for the type (~1E-15). While this might not be an issue in most use cases, it is still not an optimal result, and suggests that the calculation done in the called DLL is not optimal (it probably uses the standard formula, but because of round-off errors, the outcome is non-zero). I am posting this in the "bug" category, although it is not strictly speaking one, just to warn unsuspecting users (like me), that dealing with floating point numbers comes with its load of gotchas. Here is a snippet to experiment with the phenomenon: Again the display format of the standard deviation indicator needs to be chosen wisely to reveal the round off error.

I did that too but it broke a VI connection in one of the analysis VIs...

NI Package Manager is advertising a LabVIEW 2021 SP1 f6 version that I would like to learn about before installing it, but I am unable to find anything online. Does anyone have a better search engine (or insider trick on how to get the Package Manager to be helpful)?

Try decimate array?

This actually doesn't work as a general solution (one exception is enough to invalidate the rule, and I just experienced it). However, as stated before, I believe that as long as they don't break the code, LabVIEW's compiler hallucinations can be ignored.

LabVIEW's motto: Move slowly and break things!

Another example of tricks with units. The above formula works fine. If I want to check the value of the Boltzmann constant by adding an indicator where indicated: Things look fine but they are not: tested in LV 2021 SP1 64 bit

I date back from the pica.army.mil email list but never used Usenet. I am so not anonymous that I had a bunch of members of that mailing list drop by in one of my old labs say hi and gift me with a NI screw driver (this was back in the day where NI was gifting their users with goodies and trying to cultivate their relations with universities, just to give an idea of how far back I am talking about). I was already pestering about LabVIEW shortcomings (to my defense, that was pre-undo). Nothing changes...

Noted.

I am not sure I get it. What is that "post-processing VI" you are talking about?

Can this been downgraded to 2021 or earlier?

It starts looking like somewhere else on the internet (https://developer.ibm.com/languages/cobol/😞

So it is the new way to not release any info whatsoever ("NI did not create this content for this release") on new releases? I did not see any beta forum either during that all time. This is important to me, as I need to find funding for migrating my code base to a new environment, and any official evidence that NI/Emerson has dropped the ball to a new low (if I can forge this hybrid expression for the occasion) is useful.

Check this thread though: I wasn't able to take advantage of any multicore speed up and as for many NI toolkits, documentation is aspirational.

I think it is actually more trivial: the behavior I was observing is indeed related to an ancillary window opening, but that was triggered by a user-selected menu item. If I programmatically open the window, the "Mouse Leave" event doesn't appear to be fired (as expected). In fact, going to the menu bar triggers a "Mouse Leave" event. Why not. However, for some reason, the "Mouse Enter" event is not fired if the selected menu item is actually inside the window (which is almost always the case). This is what got me confused (or rather my code). So I guess my question is thus: why is the Mouse Enter event not fired when the user releases the mouse button after having selected a menu item?

It's a very dead thread but it's the one I found when trying to figure out why a "VI Mouse Leave" event is fired when I open another VI programmatically even when not activating that VI. Since that has been suggested as being the source of the OP's problem (but then NI suggested it was a bug with the Abort method), I am wondering whether this is expected behavior or a bug (which would then still be alive in 2021 SP1 which I am currently using). If this is a feature, I am trying to understand the logic: a VI is opened and set to not be inactive, yet the Mouse is supposed to have magically moved to that VI's front panel, even if it is nowhere close to it?

As mentioned earlier, I have happily left the Apple eco-system at the end of 2020, but one of my users is a die-hard macOS fan and has decided to try running my 2021 SP1 64 bit executable on a M1 MBP running Parallels Desktop 18 (Windows 11 VM). The code looks like it works fine, until some weird differences with the native Windows app start popping up. For instance, a variable loaded from an XML file is internally converted to a value that is ever so slightly different than the one it adopts on a PC (as seen in a printout of the value converted to ASCII). In an another instance, the comparison of two floating point values, loaded from two different files, which "passes" a preset criterion on PCs, fails the test on the VM... I don't see that there is any way to easily predict this type of problems and foolproof the code against them, so I believe I will just not recommend trying to use Parallels Desktop VMs to use my code on a Mac.

Have you considered variant attributes?

I have given up on using complex numbers in JSONtext after discovering this problem, so I am fine with either way but if there was a way to throw an error for unsupported types, this could prevent people like me from building on sand (of course I should have more testing of my code, but I am a one man orchestra, so that is not always an option). Note: the last point appears somewhat related to this issue: https://bitbucket.org/drjdpowell/jsontext/issues/108/from-json-textvim-does-not-return-an-error
