User Groups

A User Group, or LabVIEW User Group (LUG), is a local group of LabVIEW enthusiasts that come together to share common interests or goals. The user groups within the NI Community are segmented into different categories such as Local User Groups, Product User Groups, Special Interest Groups, and Partner Groups. Within each of these groups, you may collaborate with others on best practices, plan in-person meetups, or discuss any topic of your choice.

Organizing a User Group

User groups are typically created out of a shared need to seek advice and share ideas among a community of individuals that are working on similar problems OR applications. It is recommended that such a group align on goals for the organization, such as the following:

1. Share ideas and practices to improve the quality, performance, scalability and readability of LabVIEW code
2. Provide a forum to solicit advice from peers regarding how best to solve technical and procedural challenges when developing LabVIEW code
3. Drive standardization on stylings, code organization and tooling for the purpose of enabling greater reuse and collaboration

See the LabVIEW Community Forum: User Group List to find one near you.

Presentation Title	Abstract	Author	Demo Resources	SME Requirements
Using Object-Oriented Programming LabVIEW	This session will introduce object-oriented programming as a tool that can dramatically increase the reusability and scalability of your software. Instead of going through a purely academic exploration of the concept, this session attempts to map concepts that should be familiar to any experienced LabVIEW programming towards helping explain how you can evolve your daily programming tasks without starting all over.	Elijah Kerry	Presentation and Demo Materials Video of session	Yes - experience implementing class-based software architectures
What to Expect When You're Expecting an Error	Connecting error wires across nodes on a block diagram is one of the most common, brainless tasks performed by a LabVIEW programmer. Unfortunately, this often means that VI behavior in an error condition is a second thought, if it's even thought about at all. This presentation will cover best practices in regards to the generation and propagation of errors on LabVIEW block diagrams. You should come out of this presentation with the ability to write VIs that are not only functionally correct in an error condition, but also precisely convey their exact error behavior in an error condition.	Darren Nattinger	Slides and Recording
All About Collection Data Types	Introduction to the fundamentals of Strings and Arrays, then moving into Sets and Maps, the newest data types in LabVIEW.	Darren Nattinger	Slides, Demos, and Recording

Moving from SVN to Git with LabVIEW	Git tends to be the standard versioning system used in software development. DevOps platform like Gitlab and Github rely on it. Git could be a necessary transition to implement CI/CD. From my experience and with data collected earlier this year, it seems that SVN is still used by many people in our LabVIEW world. I want to share my journey from a former SVN user to a happy Git one and help developers to go further than just a "backup" tool. Real experience and no command-line inside.	Olivier Jourdan	YouTube Recording	Yes - familiarity with SCM, Git and SVN. Qualified presenters include: Olivier Jourdan, Fabiola De la Cueva and Emilie Kia
Team Based Development with LabVIEW	This session will provide an overview of best practices and tooling that should be used to streamline LabVIEW development by a team of developers	Elijah Kerry	GitHub Repo for slides and demo materials	Yes - CLA-level knowledge of how to manage and coordinate development activities across a team

Presentation Title	Abstract	Author	Demo Resources	SME Requirements
An End to Brainless LabVIEW Programming	There are lots of supposed "best practices" we do in LabVIEW without thinking. If we actually think about them, it turns out they may not be best practices at all.	Darren Nattinger	Slides and Recording
Industrial Communications in LabVIEW	Don’t underestimate the complexity of industrial communications protocols, nor the completeness of LabVIEW toolkits for supporting these. This presentation collates crowd-sourced data on the woes and wahays of integrating National Instruments systems into an industrial network, providing any developer with an up to date and pragmatically authored review of the state of current capabilities and maybe a brief look into the future. Dr. Richard Thomas, a founding member of GDevCon and the ALA, LabVIEW Champion, CLA and CLED, has worked with LabVIEW and NI systems for nearly 25 years, in various roles from Academia, Consultancy to Production Engineering, with experience in several industry sectors.	Dr. Richard Thomas	Recording
Communicating intent through the VI Icon - Jesper Kjær Sørensen (GPower)	This presentation is one you don't want to miss. We will embark on a quest through the massive Icon Dungeon in the land of LabVIEW. The goal is to slay the dreaded default icon Dragon, which has brought much pain and suffering to LabVIEW developers. We will wander through the multi-level halls of VI icons to search for traps and recover the ancient knowledge of visual grouping. We will be spelunking into the Casm of Class icons. Finally, we will enter the Vault of Glyphs to fill our bags with loot and make a quick getaway through the dimension of Automation. My name is Jesper Kjær Sørensen. I am a level 5 Systems Engineer aboard the fantastic vessel GPower, hailing from Denmark. I have replaced my character sheet three times over the past 14 years since I graduated from the University of Aalborg. Throughout the years, I have honed my skills in LabVIEW and TestStand and dabbled in the dark arts of Python programming. I have several side quests involving photography, dairy cows, my family, and my love for Dungeons and Dragons.	Jesper Kjær Sørensen	Recording

Quentin "Q" Alldredge	Wiki Page
Smartphone-like User Interfaces in LabVIEW	Do you want more advanced User Interfaces than you can normally get from LabVIEW? Maybe the user experience needs to be for a touch screen similar to common smartphone interfaces. I’ll show tricks to using the QControl Toolkit to create swipe, scroll, and selection via a touchscreen.	Quentin "Q" Alldredge	Wiki Page
How to successfully scale UIs in LabVIEW	All started with a tough requirement: “The application needs more than 50 Synoptics” . With such a breath taking number, you need to think in a way of programming User Interfaces that is easily scalable, flexible and maintainable. As a programmer, the last thing you want is to have the need to implement a new feature and have to repeat the same piece of code in 50 different places. This presentation navigates through the process of getting a successful approach, from the idea to the implementation.	Iker Segovia Revilla(ULMA)	[Video]
