NIWeek 2017

It feels strange to be saying this in May, but it’s almost time for NIWeek 2017!

For those of you attending NIWeek, please stop by the UX (User Experience) feedback area in the Expo. My teammates and I will be gathering feedback on a variety of topics. Come prepared to tell us what you would change about LabVIEW if you had a magic wand that could grant any wish!

And if you can’t join us in Austin for this event, be sure to check out the livestream of the keynotes so that you don’t miss all the exciting LabVIEW news!

LabVIEW 2016 and NI Technology Preview

by Christina in LabVIEW, NI Week

Comments closed Comments

NIWeek 2016 was awesome and inspiring. Thank you to everyone who attended, presented, or worked on the logistics of this amazing event!

The big news for LabVIEW was the release of LabVIEW 2016 with a new addition to the G language. (We don’t get to say that very often.) Jeff Kodosky, the Father of LabVIEW himself, presented on Channels (also known as Channel Wires). I wish everyone could have attended these sessions to see Jeff’s enthusiasm for this language construct, which makes communication between parallel loops easier to configure and more recognizable on block diagrams. And his plans to extend their capabilities could make them even more powerful in the future!

The most exciting aspect of NIWeek for me personally was the official launch of the NI Technology Preview. If you participate in the program, you’ll be able to see some of the things that I’ve been working on in recent years and provide feedback to shape the future of NI’s software platform.

Finally, the big news for NIWeek itself is that NIWeek 2017 will be held May 22 to 25, so attendees won’t have to endure sweltering Texas heat! I hope to see you there!

Filtering Search Results in LabVIEW 2015

LabVIEW 2015 has a few “unpublished” features, like the hyperlink display text that I mentioned in my previous post.

These features have some rough edges but are available if you want to experiment with them and give feedback to the R&D team.

One of these “secret” features is the ability to filter search results.

If you use the Find dialog (Edit>>Find and Replace or Ctrl+F) and get more than one result, you see the Search Results window:

SearchResults

To filter these results, just start typing. A box appears with the filter text and the item count shows the number of items in the filtered set.

SearchResultsFiltered

To filter the test results further, include multiple filter terms separated by spaces. Only results that include all the terms will be shown.SearchResultsFilteredAND

LabVIEW 2015

It’s NIWeek 2015, and NI has announced LabVIEW 2015!

Check out the press release, watch the What’s New in LabVIEW video, and read about the new features in the Upgrade Notes.

The biggest “new feature” isn’t really a feature… it’s improved performance and stability. Customers have told us how important these are, and NI has continued to prioritize these enhancements.

But there are plenty of other enhancements as well. Here are a few of my favorites:

  • Easy hyperlinks in free labels. Just type a URL (http://ni.com) into a free label and it automatically becomes an active hyperlink. Here’s a secret trick that we’re not publishing in the documentation yet: if you put text in angle brackets after the URL, it will become the display text. Try it out by putting http://ni.com<National Instruments> into a free label and then committing the edit.
  • Right-click (shortcut) menu plug-ins. Not only does LabVIEW 2015 include a set of handy additional shortcut menus, it contains a mechanism so that you can write your own!
  • Add and remove space. You’ve been able to Ctrl+drag to add space to diagrams for some time, but now you can also Ctrl+Alt+drag to remove space. And the results are “live” in both directions! Try it out to see how great it looks.
  • Array probes show multiple elements. This is so nice when debugging. Array probes “size to fit” their panes.
  • No prompts for subVIs from missing components. If you’re opening a VI that uses a toolkit, module, driver, or third-party add-on that you don’t have on your machine, LabVIEW won’t stop the load process to ask you to locate it. When the VI finishes loading, LabVIEW will tell you which components were missing.

If you can’t join us at NIWeek this year, be sure to check out the live stream of the keynotes at http://www.ni.com/niweek/livestream/

Darren Nattinger of LabVIEW R&D will be onstage on Tuesday (August 4, 2015) to show some of the LabVIEW 2015 features!

Silver Decorations in LabVIEW 2014

by Christina in LabVIEW

In LabVIEW 2014, we’ve added a Decorations palette to the Silver category. It contains some shapes that we believe work well with Silver controls.

The palette looks like this:

SilverDecorations2014[Note: You may notice I have the Silver category configured as my top category. You can change visible categories by clicking the Customize button and selecting Change Visible Palettes. You can reorder the categories by dragging the handle to the left of the category name].

This palette contains four of the previously-unpublished decorations that we added to LabVIEW 2011 (which you can see in New 2011 Decorations.vi).

Some of the Silver decorations look different on Windows than they do on Mac/Linux, specifically with the gradients, drop shadows, and anti-aliased circles.

Windows_SilverDecorations

Silver Decorations Mac

I also added a new decoration to 2014 which didn’t make it to the palettes. It’s a rectangle with very slightly rounded corners. The advantage of using this decoration over using a similar bitmap image is that this decoration can be resized and colored.

Feel free to use it in VIs, but note that if you save it for versions earlier than LabVIEW 2014, it will change into a regular rectangle.

Blog Shutting Down, Hopefully Temporarily

by Christina in Administrivia

Comments closed Comments

I regret to say that the Eyes on VIs blog will be shutting down on Wednesday, August 13, 2014.

I hope to find a different web host to bring it back later.

I’ll let everyone know via Twitter (@eyesonvis) if/when the blog finds a new home.

Edit: One of my colleagues at NI is going to help me get the blog on a new host! If we can’t get it up and running before the current hosting ends, it might be offline temporarily, but it should be back. Thank you to all of the others who offered to help with hosting!

QuickBold

by Christina in "Hidden" Features, LabVIEW

Comments closed Comments

Have you ever been editing text in LabVIEW and tried to use Ctrl-B to make text bold? It doesn’t work, because Ctrl-B is the keyboard shortcut for Remove Broken Wires.

In LabVIEW 2013 and later, however, you can use Ctrl-B to make text bold with the INI token QuickBold=True.

It’s not an official feature… more like a lab experiment that we’ve let out into the wild. It’s highly unusual for an application to use the same keyboard shortcut for completely different menu items based on the current state of the editor. But, I have to admit, in practice it seems pretty intuitive.

The reason this can work is that Remove Broken Wires is disabled while you are editing text. The unpublished INI token re-enables the menu item and makes it perform the same action as selecting Style>Bold from the Text Settings pull-down menu on the toolbar. So, to be clear, it only works in situations where you have text selected and the Text Settings ring is available.

If you use this “hidden feature” and think NI should make it the default behavior for LabVIEW, please consider voting for the suggestion on Idea Exchange.
