I found some spam on the wiki and would like to request deletion, but there doesn't seem to be an option (probably because I don't have the rights). So, is there a way to notify administrators (currently only @Michael Aivaliotis?) directly or should we open new topics here? Here are the offending pages.

boolean or Boolean? and other wiki style questions...
LogMAN replied to Aristos Queue's topic in Wiki Help
LabVIEW doesn't backfire for misspelled words, which means we don't freak out every time we see one. Here are a few suggestions for draconian rules on the LabVIEW wiki 😇 1.1 Uploading sample code to the wiki Put input terminals to the right, output terminals to the left (on the block diagram and VI terminals) Use backwards wiring Show terminals as icons Don't use shift registers (use local variables instead) No error handling (disable debugging) Take a screenshot with your mobile phone (compress as much as possible before uploading) Seriously, though. The wiki should have some guidelines for the structure and content of each article. Otherwise it will decay to some kind of link collection (formally known as favorites) with no added value (example). Those guidelines should be more general, as in: A page must be informative It should focus on one topic (create new pages for other topics) Citations must be marked clearly using the format "<blockquote>Someone said this!</blockquote>" ... My point is: This page should be updated (last edited on 7 October 2007, at 11:18): https://labviewwiki.org/wiki/LabVIEW_Wiki:Manual_of_Style -
I don't think they found the documentation, just an answer to their particular question or a solution to their particular problem. As Rolf mentioned above: Documentation probably still doesn't exist.

No, that is not possible. Here is the official KB article from NI https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019LtOSAU&l=en-US

Very strange indeed. You are right, these extensions should not affect any of this. I just installed the "Disable JavaScript" addon and can reproduce your behavior with the download button and version selection. In my earlier post you see the "normal" page. This is how it looks with JavaScript disabled: Also, the download button now statically points to http://www.ni.com/en-us/support/downloads/software-products/download.labview.html#
-
You need to change the location manually at the bottom of the page. After that you should always get to the same site. That is strange indeed. I just tried on another browser and can't seem to recreate this behavior, no matter which location I choose. Do you have extensions installed which block JavaScript or tracker? They can sometimes cause strange results like this, especially if contents are dynamic (as the download button or the lock for Linux/Mac versions).
-
The link at the bottom will bring you to this page http://www.ni.com/en-us/support/downloads/software-products/download.labview.html#305508 You just have to select 2018 SP1 Patch and click download. This will download the f4 (latest) patch. The en-us version is pretty stable in my experience (except for a few dead links here and there). Can't say much about the others. I'm still surprised they bother to check the associated SSP. Considering that the License Manager checks it anyway.

Here are some additional pointers that might be helpful LabVIEW Help : https://zone.ni.com/reference/en-XX/help/371361H-01/lvconcepts/custom_cont_ind_type/ UI Interest Group : https://forums.ni.com/t5/UI-Interest-Group/ct-p/7019?profile.language=en LabVIEW Playlist (see NI LabVIEW UI Tips videos) : https://www.youtube.com/playlist?list=PLE91C12E1A5E62F88 I also found a blog post with pictures that show the general process for customizing controls. https://www.dmcinfo.com/latest-thinking/blog/id/9428/basic-labview-ui-control-customization If you are interested to see what is possible with LV, search for "2016 NIWeek - Designing Advanced User Interfaces in LabVIEW". https://lavag.org/topic/20645-labview-videos-tecnova-download-site/

Disclaimer The following details are oversimplified for the sake of clarity. Feel free to point out important details that aren't covered by this post. --- There is a higher chance of finding better results by searching for "labview reference". Here are a few examples. https://labviewwiki.org/w/index.php?search=reference&title=Special%3ASearch&go=Go https://labviewwiki.org/wiki/Control_References http://www.ni.com/example/28769/en/ That said, you should be familiar with the normal data flow in LabVIEW. Data goes from one end of a wire to the other. A branch in the wire will create a copy in memory if either branch of the wire is changed. Loosely speaking, a wire represents the data. A refnum on the other hand doesn't represent the data, but the location of the data in memory (*). It is similar to a pointer in C-like languages. This changes the behavior of the wire Data still goes from one end of a wire to the other. Each branch of a wire receives exactly the same value as the other (no copy is made). (**) In order to access the data you need to make use of Property Nodes, Invoke Nodes and more. The benefit is, that you can access the same value from different places in your program. Even better, this is not limited to controls. It works for controls and indicators, VIs, objects, the project, the whole application and everything. https://labviewwiki.org/wiki/Refnum http://zone.ni.com/reference/en-XX/help/371361R-01/lvconcepts/controlling_front_panel_objects/ However, it doesn't work for variables and due to its nature, race conditions can occur if you don't take care of the execution in your program. This is why for variables there is a more specialized type of reference, the data value reference (DVR). It allows you to access the same variable in memory from different places in your program. http://www.ni.com/product-documentation/9386/en/ There is obviously much more to it than these few points. However, the links above should give you some insight. (*) Here is some information about the memory structure of a refnum. https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019ZT5SAM&l=en-US (**) Technically speaking a copy is still made if you change the "value" on either branch of the wire, but since it is a pointer you shouldn't change it under any circumstances.

How do you organize important posts and code you read
LogMAN replied to 0_o's topic in LabVIEW General
Brain power and Google is the standard solution if the search box at the top doesn't satisfy you. That said, I'm using firefox, so Pocket is one way to keep track of it. https://www.mozilla.org/en-US/firefox/pocket/ And of course you can make use of bookmarks in your favorite browser, but chances are high that it grows so much that you need Google again. Most of it can be done with Pocket. You get a button which you press while on the page. It stores the page in your Pocket (online) and you can add tags to it. You can also subscribe to an RSS feed of your personal pocket. But it doesn't update contents in your Pocket automatically and the RSS feed only contains the things you add to the Pocket. For live updates I suggest using the notification feature of Lava (mail based). Rest assured, searching was involved. hooovahh summarized it perfectly. To collect the information on your local computer you can use any feed reader you like. But I highly doubt there is any that automatically downloads attachments for you (because that is web scraping, not news reading). -
For reference, here is a comparison of how it was done before Stall Data Flow existed (prior to 2017). https://forums.ni.com/t5/LabVIEW/Darren-s-Occasional-Nugget-01-05-2018/td-p/3738420?profile.language=en

strip a file path into just the root directory and open it
LogMAN replied to rscott9399's topic in LabVIEW General
You are right, that is the standard way to do it, if you know how many elements to remove. You can also utilize the Common Path returned by the compare function depending on what you need. -
Thank you very much, this just made my day 🤣 You'll find the function on your palette under Timing. Alternatively press Ctrl+Space and write "Stall Data Flow", it should appear in the list.

strip a file path into just the root directory and open it
LogMAN replied to rscott9399's topic in LabVIEW General
If I understand you correctly, there is a path like "C:\a\b\c" and you need the "\b\c" in order to use it as "D:\default\b\c", right? Use this to check if one path is relative to another http://zone.ni.com/reference/en-XX/help/371361R-01/glang/compare_two_paths/ It returns the relative part which you can combine with your default path. I don't have access to LV right now, but this should be straightforward. -
@Dataflow_G You should revive this topic 😉

How can I improve while loop speed on windows?
LogMAN replied to LAVA Good's topic in LabVIEW General
There are multiple ways actually. Here are a few that come to mind: Let it run faster by adjusting the code inside the loop accordingly Split it into multiple loops to utilize more cores of your CPU Buy a faster computer Note that there is a limit to how many concurrent threads LV supports: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000PARmSAO&l=en-US The maximum speed of a while loop is only limited by the speed of your CPU at 100% load (and of course the way your operating system shares the CPU between processes and threads). That is assuming your loop does nothing, which makes it pretty useless. Of course, if your computer has multiple cores, you can run multiple loops in parallel to make use of them. This is contradictory to your first statement. I suppose you mean to increase the loop speed, right? If your code is simple, it should be easy to optimize for speed or to run multiple instances concurrently if applicable. -
Lost UDP packets due to ARP

Lost UDP packets due to ARP
LogMAN replied to Michael Aivaliotis's topic in Remote Control, Monitoring and the Internet
Here are some links to MS Docs that might be helpful: Using the Address Resolution Protocol Description of Address Resolution Protocol (ARP) caching behavior in Windows Vista TCP/IP implementations The second one is for Vista. I couldn't come up with any information on W10, so details can/will differ. Not sure if I misinterpret the information, but shouldn't the ARP table keep updating (i.e. not sending additional ARP requests) while packages are being transfered, or is this limited to TCP? If an entry is not used for a time between 15 to 45 seconds, it changes to the "Stale" state. Then, the host must send an ARP Request for IPV4 to the network when any IP datagram is sent to that destination. RFC 826 only mentions timeouts briefly: It may be desirable to have table aging and/or timeouts. The implementation of these is outside the scope of this protocol. -
I just had this issue and found a way to reproduce (and fix) it: Create a new VI in a library (use the right click menu of the library to create the VI). Place the VI on the block diagram of another VI The VI is only selectable if the selection goes completely around it. To fix it, open the icon editor on the offending VI and simply press OK to close it. Now selection works as expected (i.e. partial selection selects the VI).

Style Tips for Spaghetti Block Diagram
LogMAN replied to TUzzell's topic in Application Design & Architecture
Good point. Now that you mention it, the output of the multiplication functions are connected to a VI that (as far as I can tell) builds status messages and updates the progress bar (see the references connected to it). The output of that VI is displayed on the FP at a rapid pace. The VI obviously has too many responsibilities and should be split into multiple VIs. For example: Calculate Progress Calculate Estimate Time To Complete Calculate Estimate Time To Next User Action Display Progress Display Status Message Display Time To Complete Display Time To Next User Action These VIs can be put in sequence, which makes it very easy to follow. It's also much more reusable than the current solution. I'm well aware that the example above is probably too fine grained for the purpose of this application, but there is a high chance that each of these VIs can be reused multiple times or even omitted if not needed. That is not possible with the current solution. That is probably why there are two Boolean constants attached to the VI right now (i.e. too enable features that are only required in this particular section of code).
