When you want to create a diagram quickly in LabVIEW, you should use Quick Drop . But once you have all of those objects on your diagram, it still takes quite a few clicks to wire them together:

What if you could tell LabVIEW, "Wire these objects together for me in a way that makes sense"? With the press of a few keys, you can, with the Wire Multiple Objects Together shortcut for Quick Drop. With this shortcut, all you have to do is highlight your code as shown above, then press Ctrl-Space, Ctrl-W:

If you want LabVIEW to clean up the selected code after wiring, press Ctrl-Space, Ctrl-Shift-W instead:

>> Download the plugin here and try it out in LabVIEW 2012 and later. Based on user feedback, the Ctrl-W shortcut may be included with LabVIEW in a future version!

Want to inspire confidence in your technical skills--leading to promotions, new opportunities, and higher pay? Thousands of certified professionals all over the world have proven their knowledge and skills with NI products by successfully completing NI certification exams. For developers and engineers using NI software, certification is a proven way to boost career potential.  For organizations, certification is a strategic investment that pays off in increased productivity, reduced turnover, and an overall competitive advantage.

 

What are the Benefits of Being Certified?
NI certification demonstrates that you have the skills needed to create high-quality applications with NI software platforms and gives customers, peers, and employers confidence in your abilities. A recent survey of NI Certified LabVIEW Developers revealed tangible benefits that have a direct, measurable, and positive impact on employee and manager alike, such as:

LabVIEW user groups meet regularly to share programming techniques, application design patterns, tips and tricks to make NI LabVIEW work for you, and new LabVIEW technology, like the iOS and Android mobile apps released this week.

 

Sometimes LabVIEW user groups, like the Rocket City user group in Huntsville, AL, redesign LabVIEW to make it yummier than ever before. Nothing beats a sugar-loaded serving of graphical system design.

Replacing a manual hydraulic fracturing process that originally required multiple operators can be costly and complicated, but engineers at Data Science Automation were able to create a new acquisition and control system that requires only one operator.

By working with LabVIEW, a new system was easy to create and implement. This cut out the complexity of numerous operators and allowed for more focus on safety-critical aspects of the process. The new LabVIEW based system also generates a higher level of consistency and more reliable results.

By using Active X or the NI LabVIEW Report Generation Toolkit you can match your timestamps in LabVIEW with your timestamps in Excel.

To mimic program logic control codes in LabVIEW, you can use multiple while loops so the function can update in real time and update based on logic in that moment.  This code can be tailored for any use you may need.

Here’s a file path to filter out unnecessary data, allowing you to automatically update the file path so your VI will only save data that meets your special criteria.

This front panel template tool can be integrated into LabVIEW to allow you to select a VI in memory or browse to a VI on disk.  You can also use this tool to change a VI’s front panel indicator and controls.

Flash isn’t the only program that can make animation. LabVIEW can too! By reading and sequencing image data together, LabVIEW can animate your 2D images.
