LabVIEW Idea Exchange

When manually analysing a project, we can set the target in which the VIs should be loaded. Unfortunately, VIs with RT code are often broken under windows, leading to wrong test results, or even worse, pop-ups asking for VIs.

Please add an Application Reference Input for the VIAn Run.v.

Maybe this option could also be useful set in the VI Analyzer configuration file?

Hi,

Following this forum thread, I post here my idea:

https://forums.ni.com/t5/LabVIEW/Modern-embedded-web-browser/m-p/4209271?profile.language=fr#M1219530

Is it possible to update the embedded web browser in order to comply with HTML5 ?

We uses external web pages to improve the user experience in out LabVIEW applications.

Currently, the Third-Party Licensing and Activation Toolkit doesn't handle PPLs. This makes creating a plugin, pay-per-component architecture difficult.  Handling licensing and activation of PPLs is needed as part of TPLAT or some other mechanism.

Swagger/OpenAPI  has become the default go to way to document and interact with rest API's.  It would be great that when you publish a LabVIEW webservice it generates the OpenAPI yml or json file (being able to generate both would be great).

Also having a right click in the lvproj webservice view that brings you to the swagger page for debugging would be helpful. 

The State Diagram Editor was a very cool tool and lots of LabVIEW users (not only beginners, far from!) are missing it!

And no, the state chart module is not a replacement for the State Diagram Editor!

Discussion here.

When creating an installer for a built LabVIEW application, it is very difficult (see here) to include an additional 3rd party installer (such as a device driver or application that your built application depends upon).  What I'd like to see is a solution that treats 3rd party installers as first class citizens.  I'm imagining a new "Additional 3rd Party Installers" page of the Installer build specification properties dialog.

This page might look something like the one in the screenshot below, allowing users to add a folder that contains the 3rd party installer files and define a command that is run inside that folder during the install process.

When LabVIEW builds the installer, it would suck the additional installer folders into the main installer and, after installing your app files and the additional NI installers, it would sequencially extract your additional 3rd party installers into a temp folder and then execute the command line to run.  This is a pretty simple scheme that would really simplify the process for end users.

I'm sure I didn't address every issue of this use case, so please, everyone, feel free to add your own ideas.  I'd love to hear your comments.

I think it would be nice if LabVIEW was smart enough to know that when I drop a For Loop around scalar inputs it doesn't auto-index output tunnels - but rather uses Shift Registers - for matching inputs and outputs.

The common use case for this is with the Error input/output - it annoys me how it becomes an Array output.

As it is already wired, inline and not broken, dropping a For Loop around it should not break my code! 

Reference or Class inputs are other use case too - I want to pass the same thing around not create an Array. 

Shift registers are better than non-auto-indexed tunnels (other option) as they protect the inputs on zero iterations.

This would remove one step required for most use cases, speeding up my development experience.

When using LabVIEW in combination with other languages, it would be really nice for LabVIEW to be able to read from and write to the stdout and stderr streams. For example, when writing a dll in C that is to be used by LabVIEW, it would be really nice to be able to see the output and error streams from within LabVIEW. As it stands you have to jump through hoops in another IDE or create a log file or some other workaround if you want to see what might have happened inside the dll to cause it to crash.

Codewars - Achieve mastery through coding practice and developer mentorship

What language is missing in this list??

Codewars for LabVIEW should be mostly community driven, but NI would have to set it up.

I would be helpful if the Python nodes supported Python Virtual Environments. One of the powerful features of Python is able to setup multiple separate environments on a single computer, it would be LabVIEW's Python integration could also leverage this. TestStand already does have this capability, so hopefully it could be quickly/easily leveraged into LabVIEW. 😁

The concept of fluent interfaces using method chaining applied to a LabVIEW block diagram would be awesome!

When calling .NET libraries from LabVIEW, block diagrams explode horizontally - the aspect ratio of the diagram can easily push 5:1 or worse (it's 10:1 in the example below). Some Method Chaining syntactical sugar would yield a more space-efficient-and-readable 4:3 to 16:9 or so.

Property Chaining is already well-established in LabVIEW - let's get us some Method Chaining!

See the first comment for footnotes...

If you have mulitple versions of LabVIEW installed, some of them show up in the "Open With" menu, but regardless of which item you select, the VI will always open in whichever version of LabVIEW was opened most recently.

Example: if I opened a legacy VI in LabVIEW 2009, closed that version of LabVIEW completely, and opened another VI using the "Open with" menu and selected LabVIEW 12..., LabVIEW 2009 is relaunched and is unable to open the VI because it should have launched in LabVIEW 2012.

The current workaround is to add all installed versions as options in the "Send to" menu, but this is not nearly as intuitive as using "Open with" would be.
