  1. While you bring up valid points here, I think there is no standard whatsoever in the community about this so far. Everybody does as he or she feels at that particular time of the day and may do it different the next day. So if you want to bring this up, it may be a good idea to document it somewhere in the wiki. Basically start some sort of recommended style guide there. Obviously not everyone will read it and even if someone does he won't be shot if he does not follow it. 😀 About your last point I would personally prefer to have different sections on the same page for now. I also don't see deprecation of pages going to happen anytime soon and definitely not as a separate task that anyone would take upon himself. If something will be deprecated in the future it will be likely as part of editing a page for other purposes such as adding information about new features or similar. And it is anyhow at least 7 years in the future as NI committed at some time to a support timeframe of 10 years for LabVIEW CG after the first NXG version was released. 😁 With the current progress of LabVIEW NXG that might be about the time it reaches feature dominance over LabVIEW CG. 😆
  2. Well in that case the remark about the DLLs having to be compiled for ARM was really off. That is for Windows IoT installations on targets like the RPi and similar boards which all have an ARM CPU (and accordingly can't run Windows IoT Enterprise either which is a pure x86/x64 install). It all depends on which C compiler they used to create those DLLs. Until Visual C 2015 or so each Visual C version come with it's own specific C runtime library that had to be installed on every target on which you wanted to run an executable or DLL created with it. While many parts of Windows are compiled with Visual C too and therefore cause the Windows installation to come with the needed C runtime support already installed this can and will vary depending on the Windows version and the amount of extra tools and utilities that you install. Also any extra custom application you install such as LabVIEW also comes of course with the necessary C runtime support that gets installed if not already present on the system, but depending on all this a particular C runtime version may or may not be present on any particular system. Basically you should never copy DLLs to a target system but install them with the proper installer for them which hopefully takes care about installing the correct C runtime support too.
  3. Windows IoT is not a normal Windows installation at all, except the Windows IoT Enterprise version. The others are really just embededded kernels without any real Win32 subsystem. Accordingly many standard Windows DLLs like kernel32.dll, user32.dll and many more are not present there. It is basically a Windows installation with a much smaller embedded kernel that only supports Universal apps from the app store. Accordingly a normal LabVIEW build application that you created on your dev machine should NOT even be able to be started as they are build for x86 and not ARM and require a fully functioning Win32 subsystem. How do you target your IoT system?
  4. There can't be as LabVIEW can't and never could load two VIs with the same name into the same application instance at the same time. So it will load the first VI, then attempt to load the second, seeing that it is already loaded, then compare the two. Obviously there isn't any difference between the two. While you could argue that the function could check the two VI names to be equal before attempting to do anything, you also have to consider that this function is not your average Joe toolkit. It is fairly advanced and there is something to say about not sanity checking every possible error on every VI boundary down several hiererachy levels. If the user of this function wants that check it's easily done before calling this function. If he forgets such trivialities he may not be the intended target audience for this function.
  5. That's because you guys call it decimal point, but in Germany one says "Komma" when you mean to devide the fractional part from the decimal part of a number. So the language is consistent there. (German does also know the word "Dezimalpunkt" but generally the comma is used). The introduction of the decimal comma started in the 18th century in central Europe, most likely influenced from the French. The English speaking countries continued to use the decimal point. Switzerland is special as one generally talks about a comma but uses a point, but it is not fully standardised in Switzerland (most probably due to the German influence since about half of Switzerland is German speaking). However in nowadays computer settings the standard decimal character in all significant OSes is the decimal point for at least the Swiss German locale. So broadly speaking the decimal point is used in most English speaking countries and the decimal comma is used in most non-English speaking European countries. While kind of confusing I find that more easily understandable than the myriads of date and time formats used 😀. Not to forget that with date and time you end up with other "trivialities" such as time zones, different calenders and even leap seconds and years.
  6. Michael, technically what you write is only true for an input array of exactly 5 elements. If you really always want to remove the last three elements the OP needs to use an Array Length node, subtract the number of elements he wants to remove from this length and wire that to the offset. In that case you can leave the size input unwired because it will default to the rest of the array.
  7. Well looks like my case but I'm not aware that I have Java Script disabled anywhere. And with another page (different number at the end) I could suddenly download everything independent on if I was logged in or not.
  8. Minimal extensions installed which should not affect this: Adobe Acrobat, Cisco Webex Extension, Google Analytics Opt-Out , Google Docs Offline, XML Viewer Chrome addons: Docs, Sheets, Slides Nothing else.
  9. I get redirected to the nl-nl page anyhow no matter what I do. And on that I can't download any versions prior to the 2019 version no matter if I only select the runtime version or if I'm logged in or not. On the page that I get to when clicking on the LabVIEW icon on the earlier mentioned download portal I get to https://www.ni.com/nl-nl/support/downloads/software-products/download.labview.html# (without the number at the end) and while it seems I can download anything (the Download button is always enabled), nothing happens except a page refresh when pressing that button. On another link with a different number at the end that I found mentioned in a forum post I could download absolutely anything, including the Linux-Mac downloads!
  10. They are revamping the download portal for their software. The idea seems to be that in the future you should be able to go through this page for all downloads and for previous versions it should only allow you to download versions for which you have a valid SSP. https://www.ni.com/nl-nl/support/downloads/software-products.html However that page is borked in many ways (as a lot on the NI webserver) and depending on from where you come it won't allow you to download anything (even simple runtime installations) even if you are logged in with an account that has an associated SSP license, or it will allow you to download absolutely everything even without valid user account login. 😭 Why am I not surprised!!
  11. It's definitely possible. But depending on how well you implement it it will possibly not be a very realiatic simulation and mostly just allow you to execute the HMI without running into errors from calling non existent hardware. A good simulation is generally non-trivial to implement and having a good architecture helps in making it not a total disaster. Personally I tend to abstract away hardware by using LabVIEW OOP and defining a generic basic class that does nothing or implements a minimalistic simulation of the hardware and make the real hardware interface in a derived class from that basic class, possibly with different child classes for different types of hardware interfaces. Another approach that goes even one step further in abstraction would be to use a message based framework like the actor framework.
  12. I did a recertification earlier this year and passed. Don't remember any question about dynamic project creation, but the X-Control questions where in there (about 3 I think) and the obligatory software development terminology stuff (which I find somewhat bogus as it often depends which software development book you have read in what the right keywords might be). They do now give a review of all the questions after you have submitted them for grading, so you can see where you did errors, and mine where indeed in X-Controls and the software development terms. Is it a bad test? Not really but some things could be arguable. I did go through the CLA recertification prep manual and also glanced through the Advanced LabVIEW Course Manual about X-Controls which helped me somewhat to pass this. Without doing that I would probably have failed.
  13. That is because it is not a valid ZIP file. A ZIP file starts always with the two characters PK, sometimes with some (selfextractor) header in front. Your file does nowhere contain the PK identifier for a ZIP file. Also try to open the file in Windows Explorer and you get an error too, and when you open it in 7-ZIP it does recognize it as gzip format, which is a different format than ZIP. The correct fileending for this file should be .gz. The OpenG ZIP library specifically only can deal with proper ZIP files.
  14. So when you run the VC++ example you get an error! Well that is hardly LabVIEW related isn't it? You must make sure that you pass the right VID (vendor ID) and PIC (product ID) as programmed in the chip. The chips should come with a default VID and PID from FTDI but it can be changed by a utility from FTDI. Check in the Windows device manager for your interface and in the driver settings you can see the VID and PID values, but they are in hexadecimal notation.
  15. Check on stack overflow! These .Net functions can misbehave for certain paths as they do not properly escape all characters (specifically the % character) that should be escaped. But they might work for the OP's use case. https://stackoverflow.com/questions/1546419/convert-file-path-to-a-file-uri new Uri(@"C:\%51.txt").AbsoluteUri; This gives you "file:///C:/Q.txt" instead of "file:///C:/%2551.txt". Also you should probably close the .Net Refnum after use.
