    After I made this post I decided to bring the LabVIEW Wiki back online. It was not easy and took several days of server upgrades and hacking. The good news is I was able to bring up all the original pages.. The even better news is I talked with @The Q and @hooovahh and we are all on the same page as to how to move forward. @The Q did a great job of stepping forward and trying to fill the void that the LabVIEW Wiki's absence had left. He's agreed to migrate all the new content he created over to the LabVIEW Wiki, from Fandom and continue to develop new articles and content moving forward on the new site. He will also help in moderating the Wiki and will be promoted to Admin rights on the Wiki. His help is much appreciated. The LabVIEW landing page created here on LAVA is awesome but the forums don't lend themselves to static content creation. Instead @hooovahh has agreed to move the old landing page to here. That will be the new home for the landing page. This will become a valuable resource for the community and I hope all of you start pointing new people in that direction. With many editors, it can only get better and better over time. Where do we go from here: Logging in. - The old accounts are still there. If you're a LAVA old-timer, then you can try to login using your LAVA username. If the password doesn't work then reset it. You can also create a new account here. I'm going to announce a day when new accounts can be created. I'm limiting it for now because of all the spam accounts that can be potentially created. There's an issue with the current Captcha system. if you are super-eager to start creating content now and want to help, send me a direct message on LAVA and I can manually create an account right away. - New account creation is now open. Permitted content: - I'm not going to put restrictions on content at the moment. Obvious vandalism or offensive\illegal content will not be tolerated of course. However, the guidelines will be adjusted as time goes on and new content is created. There's just not enough content right now to be overly concerned about this. We need content. Discussions about the Wiki. - Each article page has an associated discussions page where you can discuss issues related to that article. Please use that mechanism (same etiquette as wikipedia). General Wiki issues\questions and high level discussions can be done here. So now, if you need to add content, you can do it yourself. Feedback as always is welcome.

But if you are more of a visual learner these channels offer a chance to learn by watching others. NI Week & CLA Conference - Username: LabVIEW_Videos, Password: LabVIEW GDevCon Conference LabVIEW Architects Forum Delacor's Channel System Automation Solutions LLC Dr. James D Powell NI's LabVIEW Channel LabVIEW ADVANTAGE LabVIEW MakerHub Looking For Certification Help Certification Nugget: CLAD - Certified LabVIEW Associate Developer Certification Nugget: CLD - Certified LabVIEW Developer Certification Nugget: CLA - Certified LabVIEW Architect Connecting With Other LabVIEW Developers User Groups Online communities are a great way to connect and contribute. In addition to online there are Local LabVIEW User Groups which meet regularly to present and understand LabVIEW and NI topics. Find one close you you and subscribe or monitor topics. NI often supports local user groups, but they are in most cases ran and organized by the community. NI Week NI Week is another great way to connect with and learn. Hosted in Austin Texas once a year it is a week long conference with training, discussions, keynotes and other activities. Many previous NI Week videos can be found online but no single source is available which aggregates all marketing, keynotes, and technical sessions in one location. The best resource for content is a site setup for video hosting done by Mark Balla over the years. Summits If you hold a CLA or CLD there are specific summits for you that are free. These are often tailored presentations for a specific skill set with the focus on technical discussion and problem solving. There are two CLA summits, one in Austin Texas, and one in Europe both held once a year. CLD summits happen more frequently and locations change from year to year. Consult their specific discussion forums on NI to see when the next one is. Just like NI Week Mark Balla has several videos available here. Needing Professional Help If a project is getting out of hand and is beyond the skill level of your team, NI suggests looking at one of their Alliance Partners. Contact one in your area, and they will help try to best guide you on your project. I Want To Contribute to the Community Developing Code For Others Arguably the most difficult thing about sharing code, and reusing code, is the mind set and considerations associated with other developers using software you wrote. It is a type of mental exercise where you need to put yourself in the mind of the developer using your software. NI's Reference Deign Portal is a good resource for understanding various coding structures, and best practices for designing code for others, and can help with standardizing code for other developers.

    You know how you can change the wire appearance for a class in the class properties? As it turns out, LabVIEW internally allows for more flexibility than that dialog gives you. So I made an advanced wire editing tool...and unlike a lot of stuff I post, you can actually use this for serious projects, because it does not use any private/unsupported LabVIEW functionality! With this tool, you can set wire size without limits (with results similar to this), customize both wire layers with any 8x8 monochrome pattern, and also mess with different draw options. Strangely, a few of these settings seem to have no effect, and many of the options for one of them actually crash LabVIEW. (These ones are disabled in my tool, but you can re-enable them by editing a typedef.) Given that this is actually a documented, supported property that's officially supposed to work, I've reported this as a bug to NI; if any NI engineers see this and feel like investigating, you can refer to service request #7762024.

    Hello everybody! During a few last years I received multiple appeals to release AES library that I developed in 2011 into open-source. So, I've just done exactly this: https://github.com/IgorTitov/LabVIEW-Advanced-Encryption-Standard I released it under MIT license (which means that there are no restrictions whatsoever). No VI passwords, no uglification. LabVIEWishly Yours, Igor Titov.

    There are a bunch of objects in LabVIEW that aren't exposed in the default palettes, and are normally inaccessible except through scripting. I made a Quick Drop plugin that exposes all of these. Many of these are no longer supported, and others never were supported in the first place. Hidden ones are displayed with an "X" next to them to warn you: as I often say, be careful with these, and don't use them in any code you care about, as they can cause crashes, data corruption, and who knows what else! Download the LLB below and place it in your <LabVIEW install dir>\resource\dialog\QuickDrop\plugins folder. Then press Ctrl+Space, Ctrl+S to open this dialog. Select an item from the list and click OK, and there you go. There's some interesting/strange stuff in here! EDIT: Couple things I forgot to mention. The first time you open this (and whenever you rebuild the list) it uses two private properties on the app reference, to get the list of controls and indicators in the palette. Since this is just a property read, I'm sure the worst that could happen is a crash when you try to open the dialog, but I can't make any guarantees. Also there's some false positives for hidden items, mainly with front panel controls/indicators that come in different styles. Place by Style.llb

    Package for working with JSON. Uses high-speed text parsing, rather than building an intermediate representation as with prior LabVIEW JSON libraries (this is much faster). Allows easy working with "subitems" in JSON format, or one can convert to/from LabVIEW types. Uses the new "malleable VIs" of LabVIEW 2017 to convert to any LabVIEW type directly. JSON text makes use of a form a JSON Path notation, allowing easy and rapid access to the subitems of interest. Requires LabVIEW 2017 and install by VIPM 2017 or later.

    I just became aware of this thread and I'm not going to go back and comment on all the discussion points that have been made before, except to say: The original code which did not use a shift register was wrong, but happened the work because of a bug in the LabVIEW inplaceness algorithm. Any input tunnel should retain its original value of every iteration of the loop, so it should've stayed not-a-refnum every time, and therefore the dynamic registration should should have been lost where the loop iterated. The issue was that the left dynamic registration terminal (which is always in-place to the right one) was also in-place to the input tunnel, causing its value to be stomped incorrectly. This is clearly a bug and needed to be fixed. It violated dataflow 'rules' for how tunnels are supposed to behave, and could've made some correct programs yield incorrect behavior. This is not a change that would break a correctly written program, so it does not qualify as an "API breaking" change; this usage has always been wrong but happened to work due to a bug. (This is categorically different than changing behavior of correct code or even changing undocumented behavior, which we try strenuously to avoid.)

    Hey LAVAmaniacs! It's been a while since I poked at the LAVA server. There seems to be a lot cobwebs and dust in the server room. The LAVA software hasn't been updated in a couple years. That's way too long. I'm going to jump in and see what I can do about upgrading the LAVA back-end to the latest and greatest. This will fix many issues. Last time I tried this, it failed and I had to revert back. I didn't plan on it failing and didn't allocate time for getting tech support from Invision. This time I'm planning for the upgrade to fail and then getting Invision support involved. This means the site might be offline for a few days beyond the weekend. Sorry, but it's a small pain we have to go through for long-term stability and security. Don't worry though. This time I have a crack team to help me out:

    At JKI, we have found that a professional user interface design can make a huge difference for LabVIEW applications. That’s why we’re very proud to announce we have just released the JKI Flat UI Controls for LabVIEW, a beautiful, professionally-designed set of LabVIEW controls that we use on some of our own projects at JKI! We hope that by sharing these with the community, we can help make it easy for just about anyone to build their own beautiful and intuitive user interfaces in LabVIEW. Learn More & Download

    You can extract the labels from the type descriptor, once you know where to find them in the array. I added support for it in this open source DataManipulation library. Check out the OpenDescriptor palette. You can install the latest release (1.1.0.5) from here: https://github.com/LabVIEW-Open-Source/DataManipulation/releases/tag/1.1.0.5 (download VIP file and install with VIPM). Once installed, you'll find the "List Element Names" method under Addons>DataManipulation>OpenDescriptor palette. (It can list enums and cluster elements as well, although those are natively supported under the Variant Utilities palette.)

    Thanks to hooovahh for posting information before I could get to it. Most of you already know me but for those of you who don't, you can always reach out to me directly if you have questions or concerns about LabVIEW. As he stated, the 2018SP1 installer was not complete and wasn't supposed to go live online when it did. Our apologies to everyone who downloaded it and found it to be incomplete. The issue with the installer has been fixed and we will release the finished product/installers soon. My personal apologies that our installers were so eager to get out the door and into your hands that they didn't wait for all of the final testing to be complete. When we do our next get together at the CLA conference, LV Champions call, NIWeek, or other LabVIEW-related event, feel free to come find me and let me know how we can best improve LabVIEW to help you.

    I think it would be possible for JKI to add besides the JKI package repository and the NI Tools Network repository one more well known repositorey such as a LAVA URL to the free edition. That would not be a big deal to add I'm sure. Another option I would definitely consider, is a paid version of VIPM that costs a small fee but then allows to add custom repositories to that client. You still would need a full pro license to create new repositories but not to access them. The current license model is impossible to defend in a company as ours where you not only need a pro license to create your own company wide repository, but anybody wanting to access that repository needs that license too in order to add it to the locations VIPM will check for packages. So something like the free community edition as now with additional LAVA repository added. Then an intermediate Developer Client edition that allows to subscribe to custom repositories that everybody in a company could use. And last but not least the full featured VIPM Pro as it is now. The old OpenG package manager could more or less do the two first editions already, it is just outdated and doesn't handle new LabVIEW file tyypes properly anymore, that were coming out with LabVIEW 8 and later. EDIT: About 2 years ago we were evaluating in our company how to manage internal libraries and the distribution thereof. VIPM was considered too but the fact that every developer would need a Pro license killed that idea very quickly. If there would have been a Developer Client edition that normal LabVIEW developers could use and could have been purchased as a site license for a feasable fee, I'm pretty sure we would have been able to get that solution approved together with a few Pro licenses.

    Hi All Apologies if this isn't the correct forum to post this on but I wanted to let the community know about a new LabVIEW podcast series I am running - The Quick Drop Podcast QDP LogoQDP is a community driven podcast that I want to use to talk about LabVIEW and engineering/Science in general via a medium that I don't think we currently make the most of. So far we have 2 episodes which are available on most podcast platforms (i'll link some below too): Ep 0.1 - Intro: A brief intro to me & rasons behind the podcast Ep 1.0 - NI Linux Real-Time Controllers with Neil Crossan: I am Joined by Neil Crossan, a Certified LabVIEW Architect, TestStand Developer & Certified Professional Instructor who works in ATE development. Neil shares his experiences with the cRIO platform & some headwinds he's had using the current platform as well as addressing some of the ways he's customised and optimised the NI Linux Real-Time OS. I am actively looking for more people to do episodes on, so if you have an idea please contact me: E-mail: info@tthequickdroppodcast.com Twitter: @quickdroppod Links: Apple Podcasts Spotify Anchor Stitcher Thanks! Jono J Hobson Certified LabVIEW Architect

    Hey fellow LAVA people. I just turned 50 on April 2nd, and wanted to do something challenging for me, both mentally a physically. I'm running 10K every day for a year and raising money for cancer research. If you want to follow along on my journey, you can subscribe to the 10K365 youtube channel for the latest. Then go on over to 10K365.com and give whatever you can. Thanks, I consider all of you as friends and one of the reasons I love LabVIEW.

    Hardly "rusty". Any software that is still at 1.0.1 after years of use is made of stainless steel People just don't know how to release fully featured and tested software any more. Users have been conditioned to think that software that is continuously updated and fixed can only be good when, in reality, it is a testament to how poor the design, implementation and testing is.

    Hello everyone, I don't know if you have seen/heard about the GDevCon @Steve Watts and his chums (as he calls them) are organizing. It is GDevCon#1, some of the things I think our LAVA friends will love are: It is independent from NI, created and driven by the community Two day conference Focused on real problems encountered everyday by LabVIEW developers Open to everyone (you don't need to have any certification like CLAD, CLD, CLA, etc). The conference will take place in September 2018 somewhere in the UK. If you want to learn more, register at: https://www.gdevcon.com/ Regards, Fab

    There is still no way through scripting to replace the decals on buttons to use a different image. But using some known LabVIEW calls we can extract the image and replace it, then save it with a new file name. This has been done several times replacing the PNG image data in the CTL file. The problem I have with this is PNG images don't scale well. If I have a PNG that is 16x16 pixels on a small button, and I happen to want to make this button for a larger touch screen UI, I can but the image will look poor. LabVIEW does support some vector images mainly the EMF and WMF file formats. So using an external program Inkscape, I wrote some code that will take an SVG file (which is vector based) convert it to an EMF, and replace the decals of buttons, as well as give the CTL a PNG icon, label, and boolean text. I recently re-discovered a website that has all kinds of useful flat icons, and makes them available as SVGs. So all that is needed is to download Inkscape, download an SVG, and run a VI that I've attached. In the zip is some Example Controls I've generated using the SVGs from the Essential Collection which make controls based on 6 different templates. The JKI Flat Dark/Light, the Flatline Dark/Light, and the System Vertical and Horizontal controls. The main VI is in Replace Button Decals\Create Control from SVG.vi. I could see this being used on a repository of SVGs at some central location like a network drive, and then call something like Tools>>Generate Controls which shows a database of icons, and control types, and then generates them, rather than generating tons of controls that might never be used. Oh and I did find this pretty handy program that allows for viewing SVG images in Windows Explorer. It really helps to be able to see the icons and organize them before generating controls.

    I don't think it's just you. For my part. I work with companies that require approved suppliers so using any third party software is an admin nightmare. Because of that and the length of my whispy white beard, I have accrued my own software which is unencumbered by other licences and can be used by the aforementioned companies because I am approved. Certainly there are some features that have been added to LabVIEW when before only openG had those features (getting type def info and auto indexing array springs to mind) and Rolfs zip package is much, much faster than NIs. But a lot of the functionality was just replication of NIs (like most of the string functions). There were a few gems in there like the inifile being able to write anything (but I think MGI toolkit outpaced that and besides, I moved to SQLite a while ago now). And, as you mentioned, removing array duplicates and it's ilk. But, like you say, they are not hard to write and the incestuous dependencies means that when you want a banana you get a banana, the gorilla holding the banana, the tree the gorilla sits in and the whole jungle surrounding it. Package that with some BSD 2/3, LGPL, GPL and god knows what else ad nauseum and it makes an otherwise fine package difficult to actually use in anger.

    Perhaps old news for many, but my NI Update Service does not tell me these things for some reason (yet to figure out why, it does bring other less needed updates to my attention...) and I have not seen anything about it elsewhere either, so perhaps it is news for others as well: I accidentally noticed that 2017 SP1 has been released . It was posted one week ago, on the 23rd of January...
