The Project Explorer Files view already contains the useful "Move on Disk..." option. It would be useful if, when a VI or CTL is owned by a lvclass or lvlib, an option named "Move to Owner Folder" (or similar) existed. This option would move the selected file to the folder that contains the lvclass or lvlib that owns that file. This action would be equivalent to using the "Move on Disk..." option, but would save the user from navigating the (potentially large) folder structure to find the right folder. In short, it would save a few seconds and would help ensure consistency. It would also encourage the best practice of storing owned VIs and CTLs in the same folder as their owner lvlib or lvclass (actions that are easy to do are performed more often).

 

For example

Notes

  • It would be great if the "Move to Owner Folder" menu item was also available when multiple items that are owned by the same owner are selected.
  • A related idea: It would be useful if, when using the Items view to move an item from an owner to another, LabVIEW would pop up a dialogue message similar to the following "Would you also like to move the file on disk to folder <insert here the folder path of the new owner>?". The dialogue would contain Yes and No buttons. This would save the user from having to switch to the Files view altogether.

Thanks!

Currently, when you right-click -> "Make Type Def" on a control / constant in a library VI, the new unnamed type definition is created outside

the library.

Also, it has the default control icon: raphschru_0-1665514290538.png

instead of a library control icon:       raphschru_4-1665514883384.png

 

This leads to 3 additional tasks:

1. Drag and drop the control inside the library from the project explorer.

2. Edit the control icon to make it have the library control icon (with the horizontal slider glyph).

This is annoying because you need to copy it from another library control icon.

3. Go to the library properties and make "Apply Icon To VIs".

 

Bonus bug: If your new type contains a library-private subtype, the new control magically disappears from the project explorer when you click on it.

 

In comparison, the "Create SubVI" function works perfectly inside a library, i.e. it creates a VI inside the library and with the icon banner.

I think the "Make Type Def" function should behave the same to make library development more coherent and intuitive.

Notes

  • In the Project Explorer the functionality would be useful to count/monitor/audit the number of VIs and CTLs in a lvclass, lvlib, or in a virtual folder of these owners, etc. It would be nice to know at a glance "oh, there are 12 public VIs in this class".
  • The block diagram count functionality can become more useful in large projects and VIs. For example, I recently edited the block diagram of a VI in a DQMH-based project. The project contains 16 DQMH modules at the moment (more to be added). I wanted to check that the VI I was editing was calling the Start Module.vi public VI of each of the 16 modules (wanted to check that the VI would launch all DQMH modules). The only way to do this was to "manually" count the VIs on the block diagram. Selecting them and LabVIEW displaying "Count: 16" would have been easier.
  • In the block diagram the information displayed by LabVIEW could be more nuanced. For example, it could display the total number of items selected (subVIs, nodes, property nodes, etc), but also a breakdown based on item type: number of VIs, number of nodes, number of property nodes, etc. All these selection stats may occupy too much space for all to be displayed at once. Perhaps they could be displayed in an element that, when clicked, expands to present all the information.
  • The block diagram and front panel count functionality would enable programmers to quickly estimate the complexity of a VI. Pressing Ctrl + A on a block diagram to select all items, then looking at the selection stats would reveal the relative complexity of that VI.
  • If a whole structure is selected on the block diagram, then the count should return the count of all items contained in the diagram, not just the items displayed to the user. For example, if a case structure is selected, the number of items contained in all cases should be displayed.

Right now, there's no way to easily open show a LabVIEW project file in the "native operating system file explorer" on Linux (for me on Ubuntu, that's the the Gnome "Files" Nautilus app and I can easily open a folder from a terminal/shell by executing an `open .` command).

Side Note: In VS Code (as described in the documentation), you can open to the location of a file or folder in the native operating system file explorer by right-clicking on a file or folder and selecting Reveal in File Explorer on Windows, Reveal in Finder on macOS, or Open Containing Folder on Linux.

Let's please add this to LabVIEW for Linux! 🙂

Scroll bar should be disabled if all elements are visible! Kudo here to get a big bang for the buck sooner than the 2nd in TOP KUDOED IDEAS from 2013 with 600+ kudos (https://forums.ni.com/t5/LabVIEW-Idea-Exchange/Indicate-that-array-constant-contains-more-elements-than/idi-p/2299860). It points out that the scroll bars are not a viable method because it looks the same when all elements are visible. That is EASY to fix; disable the scroll bar if ALL elements are visible! Currently it is disabled only if an empty element is visible. Perhaps the behavior was originally by design like block diagram scroll bars as mentioned in the reason that the following was Declined, '...without this "boundary", it is impossible to create more space...' but constants can easily be stretched by border handles to create more elements (https://forums.ni.com/t5/LabVIEW-Idea-Exchange/Make-window-scroll-bars-reflect-actual-contents-of-window/idi-p/1844127).

The QControl Toolkit is a fantastic library of tools for developing reusable UI components. I think they are a great alternative to XControls. Not only does the QControl Toolkit provide me the framework for developing my own QControls, but it also ships with some fully functional QControls, my favorite probably being the tree with checkboxes.

 

I think QControls are useful enough for all LabVIEW users that they should be part of the LabVIEW core product instead of an add-on toolkit.

The smaller footprint of the Local Variables in 2010 has increased usability of the IDE and readability of the LabVIEW language. Another node that could benefit from a smaller footprint is the User Event Ref Constant.

 

Below is some conceptual artwork on what a smaller footprint might look like. Feel free to post more concepts!

The Wire Multiple Objects Together QuickDrop tool (Ctrl + W) is extremely useful. However, at the moment it cannot wire a block diagram constant to multiple destinations. It would be useful if it could.

 

Real-world example

The other day I found myself writing the following code.

1 (edited).png

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

I tried using Ctrl + W to wire the timestamp constant to each of the timestamp global variables. Currently the tool wires the constant to the first global variable only (leaving all other global variables unwired). Therefore I had to manually wire the constant to each of the other global variables, which is a tedious, manual operation.

 

Side-note: Global variables are used because they are computationally efficient (they can be read and written to very quickly). We needed code that ran in a tight loop (up to 1,200 times per second). The VI above performs the one-off initialisation of the global variables, before they start being read/written to in the loop.

It's not uncommon to accidentally leave a process hanging and to have a really hard time tracking it down.  Different folks seem to have made different "kill all VI" tools, but this should be a native LabVIEW feature supported by NI.  The tool should just work.  "Ctrl+." doesn't always work.  You should be able to push some shortcut that works even if you have a frozen modal dialog or whatever, and all running VIs are stopped, and log of which ones were stopped prints to the screen.

Currently, the TDMS File api does not offer a way to get the TDMS file size.

 

Our use case is that we'd like to limit the size of the TDMS files and span them accross multiple individual files (and I've posted an idea suggestion for adding that as a native feature, too).  To do this, we need to be able to monitor the TDMS file size, so that we can save/close the current file and then create the next file in the span for continued use (until we hit the size limit again).

Once in a while I complain about font issues in general (here, here, or here), but one of the really weird things are the font sizes as used in LabVIEW.

 

The font dialog lists them as units of pt, but for some reason they are quite different in size from the same sizes in any other applications (browser, word, etc.). LabVIEW also shows other problems, for example tahoma 14, 15 all look exactly the same... why??

 

Here is a side-by-side comparison of a wordpad document and a LabVIEW panel. Each line is configured for the indicated font size.

 

As you can easily see, LabVIEW is the exception. Any other applications I tried agrees with the left panel.

 

Idea -->LabVIEW should also standardize here!

There are times when I leave a VI with modal properties open and then I run the main application that also calls this VI if opened in the development environment. This locks all running windows due to the modal VI. I propose a button in the taskbar that aborts all running VIs OR perhaps a list is opened on right-click of all running VIs 🙂

The title says it all.

In 2021 there was excitement about improvements to LVCompare and LVMerge, however there is still no way to compare classes or libraries.

I'm ok with not merging. I know that is a minefield. But at least show me what methods were added, what library or class settings were changed, which VIs moved from private to public and for classes, diff the private data and maybe show changes to the class heirarchy?

Many times a day I need to look at the full text of an error cluster's "source" string.

The workflow for this has always been awkward.

Additionally, "Explain Error" also requires some extra clicks.

 

What if we combined all of that functionality into the context help so that, when the user mouses over a populated error cluster with context help enabled, the user can see all the relevant information quickly?

It would be really nice if double-clicking column header separators in tables, trees, and multicolumn listboxes automatically resized the columns based on their contents (like Microsoft Excel). This would be useful in these types of controls and indicators at both edit and run time. It would also be useful to have this capability interactively (initiated by the developer or user) and programmatically (through properties or methods).

You can currently pin LabVIEW projects, VIs, and other files to the file lists in the LabVIEW start dialog as shown in the pictures below:

It would be really nice if the Recent Projects and Recent Files menus in front panels and block diagrams automatically included the same files at the top of the menu item lists (and in the same order) as illustrated in the pictures below:

If I have a standard VI that's hung, I can highlight execution, and then drill into the hung VI (reentrant or not) to see what's going on:

_carl_0-1719594144175.png

_carl_8-1719594621558.png

 

But...if it's a class override method, I can't do this:

_carl_5-1719594530350.png

_carl_6-1719594541579.png

_carl_7-1719594559755.png

 

(There is technically an exception: If the override is not reentrant, and you guess the correct override in the popup, then you can debug it.)

 

This experience would be so much better if I could drill into the overrides seamlessly, without being prompted for which override to look at, and with the correct runtime instance of the override popping up.  This is the kind of thing where, on complex projects, this improved debugging could literally save me hours on some bugs.
