Case Insensitive Comparison Mode for String Equality Comparison

Status: New Submitted by Trusted Enthusiast Trusted Enthusiast on 04-29-2010 10:51 PM 21 Comment

I've been doing a lot of string comparisons lately and I really hate having to drop To Upper/Lower Case function in front of my Equal? comparisons, as shown below:

It would be so much nicer if I could just have a special Case Insensitive mode for the Equal? node (and, it would be nice if the Equal? function changed its visual appearance, somehow, to signify that it is in a Case Insensitive mode):

Option for Find (and Find all Instances) to Search inside of Disabled Structures

Status: New Submitted by Trusted Enthusiast Trusted Enthusiast on 12-10-2020 11:37 AM 1 Comment

It seems that if you have a VI (or function) inside of a disabled frame of a Diagram Disable Structure or Conditional Disable Structure then the Find and Find All Instances features in LabVIEW will not report them. I'm OK if this is the default behavior, but maybe the Find dialog should have an option/checkbox to search inside of Disabled Structures.

 

Note: This is really important for cross-platform and embedded target development where there's lots of use of Disabled Structures.

Cluster Support for "Add Array Elements"

Status: New Submitted by Member on 01-24-2023 01:53 PM 4 Comment

Clusters can be added together using the "Add" primitive:

Why not support adding them together in the same way using "Add Array Elements"?

Create a public bug-tracking dashboard

Status: New Submitted by Active Participant on 07-08-2020 01:04 AM 2 Comment

Almost every widely-used software framework, ecosystem, IDE, ... has a public bug-tracking dashboard where bugs can be:

  • reported
  • monitored
  • voted
  • ...

Jira or Mantis are quite common solution.

As a NI user, the current situation it's really frustrating: even for bugs originally reported by me, the ticket is created by a NI engineer.

And so I don't know what information it contains, its priority, if someone is working on it, if it has been already solved, ...

 

Many years ago NI was a pioneer with the community, but now is ages behind everyone else.

Back Propagation of 'Create User Event' Datatype

Status: New Submitted by Active Participant Active Participant on 01-22-2021 03:03 AM 4 Comment

I use a lot of user events and often define the user event references in a typedef cluster before actually writing the create/generate/destroy code. It would be really helpful if the Create User Event primitive would change its input datatype based on the output (i.e back propagate the datatype), much like the Variant To Data primitive.

selecting multiple elements in the array to delete

Status: New Submitted by Member on 07-07-2015 12:46 AM 7 Comment

 

 

Problem:

I faced to delete multiple elements form the array which is having 20 steps.

 

solution:

if able to select multiple elements by holding the shift key we can delete selected items 1 time and can insert 1 time.

Probe of a typedef cluster should use the typedef for display

Status: New Submitted by Member on 05-29-2022 08:37 AM 4 Comment

Probing a typedef results in a vertical list showing all the fields in the cluster.  Creating the typedef cluster often involves organizing the fields in a particular layout, setting units etc.  It seems like probing the data and displaying it in the same format makes more sense.

 

For instance, I have a cluster of camera information set up as a strict typedef:

 

STSLabs_0-1653830762726.png

 

When I probe a wire of this information I get:

 

STSLabs_1-1653830848197.png

 

This cluster isn't too big so getting to all the information doesn't require a lot of searching and scrolling, but that can be an issue.  What's more of a pain is that the default unit for angles is rad and I cannot mentally convert them quickly so I end up having to double-click each 'rad' label in the probe window and change them to 'deg' so I can confirm the data is what I expect.

 

I know I can create a custom probe to display the typedef, but having to constantly create custom probes for each cluster is a bit of a burden.

 

Am I missing something?  Is there a good reason to NOT display the probe using the typedef?

Make Edit Values table longer

Status: New Submitted by Active Participant Active Participant on 06-16-2020 03:39 AM 7 Comment

Given the properties dialog box isn't resizable, and there's nothing under the table (apart from one tick box), could you make the items table longer? It's really annoying when there are a few extra values that can't be seen because the table is too small.

Numeric constant type visualization

Similar to Visible items>Radix right-click menu it would be highly beneficial to have the same possibility for showing (and switching) of Representation.

Conditional Disable Symbols settable in Application Builder

Status: New Submitted by Member on 06-11-2009 10:15 AM 31 Comment

I use the conditional disable structure in my projects to turn debug options on and off.

At the moment before every build I have to go into the project properties and make sure that DEBUG variable is set to FALSE and after the build I have to change it back.

You can get around this by automating you build but an option in the build specifications would simplify this.

 

It would make life much more convenient if there were a list of the available (non-system) conditional disable symbols in the application builder dialog where the appropriate variables for the build could be set. This would also allow for a simple duplication of a build spec to have one with DEBUG=TRUE, and one with DEBUG=FALSE.

Right-click -> Copy Data should copy TEXT data

Status: New Submitted by Member on 04-11-2013 07:08 AM 10 Comment

When debugging (and at many other times), I want to copy data from a probe or control into a text file, Excel, whatever.

 

For reasons that I am totally unable to fathom, it copies the control as a bitmap. Print screen provides this functionality already. I think copy data should copy text instead!

I wasn't able to find this on the exchange, sorry if I missed it!

Keep block diagram layout when copying between front panels and vice versa

Status: New Submitted by Active Participant on 06-03-2022 07:03 AM 11 Comment

If you copy a group of controls/indicators from a front panel to another, the layout of their terminals on the block diagram is not maintained (instead it is typically messy...)

Vice versa: If you copy terminals from a block diagram to block diagram the block diagram remains the same, but the control layout is messed up.

 

Why not just keep both as they were when copying?

 

 

Bonus-idea: If you try to fix this by using the diagram clean-up function controls with the same name, but an iterative suffix (which the IDE is able to automatically generate itself as well, so it has a relation to it alread) the clean-up ignores the order of the names when ordering the controls...(so it might stack them nicely, but then control ...<n+1> is not put after/below ...<n> e.g. Perhaps it could be a bit more intelligent and include that in the ordering algorithm too?

Allow vertical Case and Event selector lists.

Status: New Submitted by Member on 04-17-2017 10:06 PM 4 Comment

Once in a while I encounter a case or event list that forces me to grow the structure

- in order to keep the list readable:

It would be nice if the item-list would automatically "wrap" instead.

Expanding a block diagram should only affect the case that is shown

Status: New Submitted by Trusted Enthusiast on 12-16-2019 03:39 PM 12 Comment

When I Control+Right click and drag to expand a block diagram. The expansion should NOT effect all of the unseen case frames

 

I am really tired of stuff like this happening when I expand the diagram of another frame of the same case horizontally and vertically.

 

This "Short cut" actually creates a lot more work for me as now I have to go back and clean up all the other states in my state machine that are messy now.

Enable Qualified Name in VI Properties or add copy button

Status: New Submitted by Active Participant Active Participant on 01-13-2022 03:14 AM 2 Comment

This is a really basic thing, but it would be helpful if the qualified name (as seen in VI Properties) was enabled so it could be copy and pasted into documentation.

 

When I'm writing detailed documentation to tell other developers how the software works I often use the qualified name as opposed to VI name. For example "Send Creep Command.vi" doesn't tell the developer where to find it, but "Motion Control UI.lvlib:Motion Card 2 Data.lvclass:Send Creep Command.vi" does.

 

McQuillan_0-1642064820004.png

 

I would be happy with the string being enabled (so it can be selected and copied), or a button that copies the string into clipboard.

On auto-generated class palette, properly scope available VIs

Status: New Submitted by Member on 01-26-2023 09:29 AM 7 Comment

Let's say I have a class with a few public VIs, and several private VIs and typedefs:

_carl_0-1674746142961.png

Assuming I'm not working on a VI within the class, If I'm using this class on a block diagram, I can only use the public VIs.

 

However, if I right-click on the class wire, and go to the auto-generated class palette, it shows everything.  This can be absolutely overwhelming with larger classes.  Why not scope this palette appropriately?

Add Revolution Unit

Status: New Submitted by Member on 03-02-2025 11:04 PM 1 Comment

LabVIEW's units support angular measurements of degrees, minutes, seconds, radians and steradians but I don't see support for a full revolution. If this was added, we could use 'rev/min' as a unit which is a very common unit.

 

I think that users don't really use units as much as they might because of limitations such as this. There are some other things that I would like changed with units, but this should be and easy one to fix.

Index & Bundle Cluster array should retain element names

Status: New Submitted by Knight of NI Knight of NI on 02-13-2015 11:31 AM 3 Comment

(Inspired by this discussion)

 

The Index & Bundle Cluster Array function currently discards any labels of the input data. I think it would be more useful if it would try to retain the names (i.e. copy the original array labels (if available) to the element labels of the output).

 

The picture illustrates the idea. On the left we see the current behavior and on the right what we would get after this idea is implemented.

Output of "Look In Map" should NOT be inverted

Status: New Submitted by Active Participant on 03-31-2021 08:38 PM 10 Comment

Many common functions include a "found" or "exists" output. Examples include:

  • Get Variant Attribute
  • Element of Set?
  • Config file VIs (Read Key, Write Key, Get Key Names, etc)
  • Chek if File or Folder Exists

 

Why then does Look In Map provide an inverted ("not found") output? Wouldn't it be better if it was consistent with other similar functions??

fabric_0-1617240144803.png

This is most frustrating when replacing existing code using variant attribute lookups with equivalent maps. "Look In Map" is pin compatible with "Get Variant Attribute" except for that one inverted output! This has caught me out on more than one occasion...

Overhaul the LabVIEW Style Checklist inside LabVIEW help

Status: New Submitted by Member on 08-07-2024 06:57 AM 11 Comment

The help page, that is supposed to provide a starting point for the developers on creating readable, high quality code in LabVIEW seems to be unchanged for quite some time: LabVIEW Style Checklist - NI. 

At different workplaces (including NI) and different teams I have seen different implementations of such guides, many of which included extra "rules".

One such example is the file naming convention:

  • Using spaces for separating words.
  • Using Libraries to namespace VIs instead of including the noun in every related VI.

These are the most prominent examples I can come up with from the top of my head, but I'm sure that there are more.

 

I'm curious if an updated version exists somewhere that could be used to replace the above refenced help page?

If there is not, then I think could we collect some ideas here for updating this document.
