Space constant redesign

Status: Completed
by Knight of NI Knight of NI ‎03-11-2013 02:07 PM - edited ‎03-11-2013 02:08 PM

Currently, the space constant looks very similar to an underline character, possibly causing confusion.


I think the icon could be made a bit more distinctive. Here are some alternatives I just made up. I would probably prefer (1) but I am open to any other suggestions. Smiley Very Happy

Include LabVIEW Version Number in Application Icon

Status: Completed
by Trusted Enthusiast on ‎10-13-2009 04:10 PM - last edited on ‎01-09-2012 03:34 PM by Active Participant JordanG

When you develop with multiple LabVIEW versions, it is sometimes difficult to identify which version you're using or launching based on the icon of the LabVIEW EXE:




Here's my Windows 7 taskbar with, among other things, LabVIEW 8.0, 8.5, 8.6, and 2009 icons.  Which one is which?  There are ways to tell, but it sure would be easiest if the version number were overlayed on the icon.  Note the Visual Studio 9.0 icon in the taskbar...I think we should do something very similar with the application icons of future LabVIEW releases.


NOTE: The icon should also reflect differences between the 32-bit version of LabVIEW and the 64-bit version of LabVIEW

Truncate Long Paths

Status: Completed
by Active Participant blawson on ‎02-15-2010 10:10 AM

I don't like the way that long file paths are shown in path controls and indicators:  If the path is longer than the textbox (and it usually is!), the user only sees the first several levels that fit.  This can be pretty confusing.


One way to solve this issue is to truncate the path in the middle in such a way that the filename or last folder (which is usually what's most important) is always shown.  I've seen this in other UIs and it should be a natural thing for users to understand.


Here's an illustration:



I think this should be a built in feature of the path controls and indicators, accessible through right-click menus and/or the properties menu of the control at edit time.

Integrated Structure Labels

Status: Completed
by Active Participant Hueter on ‎06-30-2009 06:11 PM

I think structures should have a better label system. Currently I use free labels of the same color as the loop which looks great and makes the code easy to read and debug. But if I resize my loop I have to manually resize the label as well. I think this should be built into a right-click option.

Advanced Code Commenting Functionality

Status: Completed
by Member Chris_H. on ‎02-14-2011 04:10 PM

Current Situation

The current commenting practice in the BD is to place free floating comment number labels and write the comment in a text field as in the example below.

Current Code Commenting Practice.png



- comment number labels do to stick to the code block. if the code number block is moved the comment has to be moved as well.

- no link between number and comment text block


This unsophisticated way of commenting LabView code lead to the lack of comments in general. Usually a new programmer can understand what happens, but not why a function is implemented like this.




LabView provides the Advanced Code Commenting Functions.





The comment block is more then just a text block. Basically it has a comment ID, the comment itself and a comment category.

By the context menu the following functions are provide:

  1. add comment
  2. delete comment
  3. move comment up
        The particular comment line is moved up in the comment block. The ID is decremented
  4. move comment down
         Opposite from 3.
  5. highlight function
         The function to which the comment ID sticks is highlighted.
  6. the comment category can be selected. (e.g.. Code Explanation, To Do, )

Adding Comments

Adding a comment in the comment block incorporates two steps (after selecting Add Comment from the context menu):

1. Sticking the automatically generated comment ID to a particular code block just by selecting the item the comment belongs to.

   This could be any type of code: wires, SubVIs, the whole Case, a particular Case, Sequences....

2. Writing the comment




Example of Block 1.png


If the mouse pointer is set over a comment ID the comment is shown like a tool tip and disappears as soon as the mouse is moved away.





  • Comment moves with function block if function is moved on the BD
  • Comment ID sticked on the BD item and ID on the comment block always match
  • generally more comments in a LabView programm through more simple way of commenting code

It has come up in discusssions that NI does not really cater to hobbyists. A cheap and functional version of LabVIEW is limited to the student edition, which is restricted to a small subset of potential users.


 From the  FAQ:

"The LabVIEW Student Edition is available to students, faculty, and staff for personal educational use only. It is not intended for research or institutional use."


As a suggested first step, I suggest to remove the academia restriction and mold it into a new product:


--- LabVIEW personal edition ---


Licensed as follows:

"The LabVIEW Personal Edition is for personal use only. It is not intended for commercial, research or institutional use."


 It would be available to anyone for noncommercial home use.


LabVIEW currently has the home use exemption that allows installing a copy at home. Unfortunately, if you lose your job, you not only lose your health insurance, but you also lose access to LabVIEW, thus hampering any self paced LabVIEW tinkering that possibly would improve future job prospects. I am sure many retired LabVIEW engineers would love some recreational LabVIEW use. They could be a great asset, because they will have more time helping out in the community and forums. They could even give guest presentations at user group meetings, for example.


The LabVIEW personal edition should include all modules of interest to the hobbyist, including application builder, embedded, FPGA, and robotics.  We should be able to distribute built applications as freeware. Support would be limited to community support.


Installing LabVIEW on every single private home computer in the world would cost NI exactly nothing (except for some sales of the current student edition which is about the price of a textbook, some internet bandwidth, and loss of the zero to two (?) multi-millionaires who actually bought the NI developer suite for themselves. Smiley Wink). 99.9% of users would never touch it, but that 0.1% could come up with great new application areas and would help spread the word on how great LabVIEW really is. Soon 0.2% would use it. Smiley Happy


It should follow the "customer class limited" Freemium model, (as defined by Chris Anderson), i.e. limited to personal home use in this case.


The running applications should be clearly identified to prevent commercial use. The splash screen and "about" screen should prominently display the words LabVIEW and National Instruments and could even be used for NI advertising and product placements, for example.



Status: Completed

LabVIEW Home Bundle is now available for personal, non-commercial use. Initially, it will be available for sale through Digilent. See product page for more details.

Currently, the block diagram has an endlessly useful feature. I use it every day - the Distribute Tool.





The following feature would be AWESOME for expediting BD readability:

Offcial support for the Chrome browser for accessing LabVIEW remote panels

Status: Completed
by Knight of NI Knight of NI ‎09-01-2013 03:10 PM - edited ‎09-01-2013 03:15 PM

As mentioned here, Chrome is now the dominant web browser worldwide, but acessing remote front panels using Chrome is still not officially supported by NI (more details and links are in the quoted thread). 



While there are some hints that several users had success back in 2010, I was not successful so far.


IDEA: There needs to be official NI support for the dominant browser and NI should invest some effort to get this working seamlessly.

Large string constants, like to one shown below, can really get in the way. I would like to double-click the border and have it collapse, like the LV 2010 Cluster now does. Putting large string constants in a VI, or rolling them up, are some work-arounds, but this would be easier...

Always Show the Connector Pane

Status: Completed
by Active Participant blawson on ‎12-03-2009 09:38 AM

My idea is simple: Put the connector pane on the front panel next to the VI icon.


Why: Right clicking to show the conpane means extra clicks that would not be necessary if it was always there.  It would also be solve the problem of saving the VI with the connector pane hiding the VI icon.

Make Case Selector

Status: Completed
by Member NelsonUWP on ‎07-31-2009 08:05 AM

I don't know how many times I've added a case statement post-programming, but I do know that there isn't an easy way to make a tunnel the case selector.  Usually I delete the tunnel and then drag the case selector down and then rewire, there should be an easier way.  For loops and while loops have an easy way to index/unindex or replace with shift register, why can't a case statement be the same?

It'd be usefull for develloper and especially application user to improve graph control by adding to Graph direct access to Plot Visible property on plot legend.


For the time being, you have to go to color and choose transparent or to change visible property dynamically.


I propose control like that ... but we could find another idea to access Visible property.

Make possible that Boolean function accept error cluster as input as this example:

It could be nice to have a context help on coercion dots to see what is the expected type of the data that is supposed to be wired to. This way you can rapidly determine what kind of conversion to use to avoid the coercion dots.

When creating a subVI from a selection, LabVIEW should do two things:

  1. Use the user's default connector pane pattern instead of selecting one matching the number of inputs and outputs. This will make easier wiring and allow users to add more IO later.
  2. If the user is using a "standard" pattern (e.g. 4-2-2-4), LabVIEW should try placing the error clusters at the bottom corners and objects or references at the top corners.

It should also try to make the FP of the subVI cleaner, but that's another matter.

Complex notes manager

Status: Completed
by Member Edupo ‎12-03-2010 04:28 AM - edited ‎12-03-2010 04:35 AM

Hello, this is my first post in this forum and I don't found ideas about this topic. I hope you like it.


Well, time ago I started to work with LabVIEW, It's powerful, but there are some kind of issues that I want to explain here. Now I'm get involved in a big project for a very big aerospace company, and I'm developing a complex application to acquire some data and process it. Well, this software is in development by some people and I have an idea for the work flow.


I explain it with an example:

If we have in every VI a little data base with some notes ordered by type or something we can read the code or we can start to work in a VI faster. Imagine that you have an event structure with several cases, and you put some notes like you can see in the following image:




Now, I'm able to revise quickly the code reading all the notes and start working only in the "TO DO" zone. But let's do a more complex design: Now I open my project explorer, and open the "Note manager" that could be like this.





Here it is the real advantage of this tool: All the design are done and now I want to improve the application. Lets go only to the notes that interest to me: "TO DO" notes. If I double click on an element LabVIEW opens for me the VI centered in the zone that is interesting for me. And some more: I can check the work I've done and I can add new notes only with a click.


The more complex the project is, the more useful is this system. So, what do you think?

Add a "Mouse Scroll" event

Status: Completed
by Knight of NI Knight of NI on ‎06-07-2009 01:55 AM

It would be nice if NI added "Mouse Scroll" (and its counterpart filter event) to the supported events. Today, you can do this by using the mouse input VIs in a separate loop and polling, but that's not a very nice solution.

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.
