If we want a ring of a string type we can use a combo box and if undefined items are not to be allowed it *could* behave as a regular ring (integer type) with no text editing/input, but that is not an option in LabVIEW now. Having such an option would allow us the keep the behaviour of multiple ring controls identical (and hence more intuitive to the users) although their types behind the scene for programmatic convenience are different.

If you want to keep the ring as a string (to not have to deal with it indirectly though the ring/enum string array property, which would be the current workaround...) you are currently forced to accept that the this ring will behave differently than other ring controls or enums:

 

In Microsoft applications the suggested feature is available by setting the style of the combo box to DropDropDownList.

 

En un mundo cambiante tecnológicamente, se requiere responder antes los nuevos retos tecnológicos y, en materia en intercomunicación de apps, estaría excelente contar con herramientas, (API, TOOLKIT etc.), fáciles de usar como se ha caracterizado LabVIEW, para poder comunicar y enviar la información que se genera por medio de LabVIEW a otros sistemas como SAP S4HANA ON Cloud, actualmente tenemos SAP S4HANA ON PREMISE y esta excelente, sin embargo, todo cambia y en algunos casos se vuelve un desafío el poder cambiar con transparencia y facilidad, estoy seguro que es posible desarrollar diversas herramientas que pueda compartir la información que se genera desde el hardware de NI, a cualquier otra plataforma que los diversos clientes requieran, en nube, dispositivos móviles etc.

It would be great if one could mark certain files as having an absolute path so that it is easier to move projects that use a common resource around in a multi developer/station environment.    

 

A project might for example require a shared library or file that is installed by another application into c:\XXXX

Currently, all developers must place their project at the same relative folder depth to the shared resource to avoid linking issues.  e.g If Developer A uses c:\Users\Dev A\Project\  then Developer B would need to use  c:\Users\Dev B\Project\..   The project would complain about not finding the shared resource if Dev B was to use  c:\Users\Dev B\Repos\Project instead for example.


Marking the shared files as having an absolute path would resolve this

(NOTE: This idea is the opposite of this one, so not the same)

 

The properties page of "boolean array to number" should prominently include the sign extension mode so we don't run into this confusion.

For string controls and indicators please add a vertical alignment option. We have applications where we will programmatically change the font size, which requires a string control/indicator to be sized for the largest option. Since there isn't a vertical alignment option, the string is always aligned to the top and it can make the front panel layout look strange.

 

Other applications have long strings that may be a single line or may be a variable number of multiple lines, but we'd like to be able to center the text vertically. Again, this requires the control/indicator to be sized for the largest option, but all the text is always vertically aligned to the top of the front panel object.

Currently, on Windows, File:Save As:Rename does not work when changing only the capitalization of a filename. I would prefer that it did. See this discussion for workarounds.

Has no affect on the filename in the finder or in LV.

 

It's always a pleasure to uncover shared memory problems when working with base vi.lib methods that *should* work as preallocated clones and have uninitialized shift registers and then having to establish a chain of vi references to safely call those methods in an application with distributed/parallel threads. It feels like extra work but does fix the problem. It's a major unknown gotcha unless you're already familiar with the vi you are calling.

 

My most recent hiccup: the NI PID library. I needed two closed loop controllers in actor framework, and was getting very strange timing, setpoint, process variable, and control output crossovers until I realized the stock .vi's had shared memory in the form of uninitialized shift registers (despite being in the context of a pre-allocated actor). Creating references of the vi's I needed and storing them in the actor at launch fixed the problem, but at that point the effort in writing my own PID .vi starts to be a favorable time tradeoff. At least I am able to peek under the hood of the PID library, other aspects of vi.lib... not so much.

 

Or maybe this is a teaching problem. I haven't come across ways of navigating this issue from official NI documentation, in fact the way I learned I needed to call the PID.vi by-reference was from the forum and rather matter-of-factly. There are a couple of great blogs that cover this issue in detail, so I don't feel alone in my ignorance. Maintaining State Information in LabVIEW Applications, Part 5 - LabVIEW Field Journal Archives | LabVIEW Field Journal Archives

Problem: Currently, the native nodes and VIs that can be used for error manipulation are located in the Dialog & User Interface palette. While manipulating errors can mean generating dialogues, and can influence the User Interface/User Experience, error manipulation is a broader and stand-alone topic.

 

Solution: Nodes and VIs that are relevant to error handling/error manipulation should be given their own subpalette inside the Programming palette. The new subpalette could be named "Error Handling", "Error Manipulation" or "Errors".

I often find my self right-clicking the VI, either in the block diagram where it's used or on the icon at the top-right, but each time I'm reminded that this function does not exist (yet!). It would be really useful when navigating in large projects if you could right-click the VI and find it in the project. Often I want to get to its class to find other VIs that I'm looking for and sometimes to check where the class is used by the rest of the code.

I couldn't find this explicitly mentioned here, but it seems related to:

 

Block diagram references should be 16 pixels tall (currently 19 pixels) - NI Community

Same Height of Unbundle by Name / Terminal / Local Variable - NI Community 

 

Although making changes like this could hurt legacy code, earlier implementation is preferable. Local variables are already the same size as bundles and property nodes, but constants are not. My suggestion is to increase the size of bundle/unbundle elements by one pixel and decrease the size of constants by two pixels by reducing their border thickness. Since numerics require a type indicator, a 1 px border wouldn't compromise recognition. Numeric constant type visualization - NI Community


You cannot currently install MAX as a standalone product- you need to install it along with something else. I need MAX on basically all computers I build my installers for, so I always go into the Additional Installers menu on the Application Builder, then pick (usually) "DAQmx with Configuration Support". Unfortunately, this also means I have to uncheck "Automatically select additional installers" so I can go find the "Configuration Support" item.

 

I almost always want to let the App Builder pick my additional installers for me, so I will check "Automatically select", then uncheck it, then go check the box for "...with Configuration Support" for one of the items that got automatically selected.

 

I'd like a box that lets me prefer the "With configuration support" version of whatever I'm building so I can make sure MAX gets installed. For my use, it doesn't seem to matter if I pick "DAQmx with config support", "VISA with config support", etc.

 

I'd ask to make MAX a standalone installer, but that would require me to uncheck the "automatic" box to add MAX to the list, which doesn't really help. I just want to say "Hey Appbuilder, figure out whatever you need, and ALSO install MAX."

It would be really nice if you were able to resize properties dialog boxes for controls, indicators, constants, and other nodes on a front panel or block diagram. Sometimes the information entered in a dialog is larger than the allotted space. Fortunately, in those situations, there is usually a tip strip that shows all of the information rather than just the visible portion of the information, such as shown in the enum properties dialog box picture below. To make all information visible, it would be great if properties dialog box windows were resizable and the contents of the tab control pages automatically scaled with the size of the dialog. It would also be nice if pages containing objects with columns (e.g. multi-column listboxes, etc.) allowed the columns to be resized as depicted in the picture below.

For anyone that has used CAD software, you know how much of a timesaver this feature is. It is very similar to quick drop but relies more on graphical selection than keyboard input (although, these shortcuts often allow text entry as well and have a configurable menu).

 

For example, pressing the "S" key in SolidWorks pops up a contextual, configurable menu at the current cursor position that allows you to rapidly click on common operations as well as customized shortcuts.

 

I have my own janky extension to quickdrop that makes a graphical menu present after pressing multiple buttons (ctrl+space, ctrl+q, then one of WASD or a mouse click on the popup .vi front panel), but it would be nice if I didn't have to go through multiple shortcut selections to hit my toolbar-of-target. Said another way, a more extensible quickdrop-like shortcut bar would be nice. Something like the right click and shortcut keypresses for Autodesk Fusion and Solidworks are the inspiration.

If you e.g. open a project in a newer LV and then close it; it starts recompiling everything with no abort option, and only after having recompiled 2000 VI's i can choose to _not_ save them ...

I just opened it to check a few things and ended up with Kill Process to get out of it.

 

Let us cancel/abort the recompile when shutting down.

Many new PCs running Windows run on ARM processors (like the Snapdragon), rather than x86 architecture. LabVIEW does not support ARM.

 

A few years back, my LabVIEW software would work on any Windows PC. That is no longer the case. That is a huge and increasing limitation.

This topic keeps coming up randomly.  A LabVIEW class keeps a mutation history so that it can load older versions of the class.  But how often does this actually need to be done?  I have never needed it.  Many others I have talked with have never needed it.  But it often causes problems as projects and histories get large.  For reference: Slow Editor Performance with Large LabVIEW Projects Containing Many Classes.  The history is also just added bloat to your files (lvclass and any built files that use the lvclass) for something most of us do not need and sometimes causes build errors.

 

My proposal is to add an option to the class properties to keep the mutation history.  It can be enabled by default to keep the current behavior.  But allowing me to uncheck this option and then never have to worry about clearing the history again would be well worth it.

I want an event to trigger when the user switches from linear to logarithmic mapping for a control.

None of these currently existing events trigger for this scale change

Control and indicator references are currently 19 pixels tall. They should be 16 pixels tall. References would then align better with other items which are already 16 pixels tall, such as the Bundle By Name and Unbundle By Name nodes.

This idea is inspired by this idea and this idea.

Idea Part 1: The menu that appears when right-clicking an input of the Replace Array Subset node should contain Add Input and Remove Input options.

Idea Part 2: The QuickDrop Remove and Rewire tool (Ctrl + Space, Ctrl + Shift + R) should remove unwired inputs of the Replace Array Subset node.

This would be similar to the menus of several other well-loved nodes, such as the Build Array node.

 

Real-world example

The other day I wrote the following code:

Initially all the inputs of the Replace Array Subset node were wired. Then I realised I had made a mistake, and needed to remove the third-last pair of wires. I deleted the wires. So far so good.

 

I then selected the node and pressed Ctrl + Space, Ctrl + Shift + R to execute the QuickDrop Remove and Rewire tool, in the hope that it would eliminate the unwired input. It didn't. I then right-clicked the input, hoping to manually select Remove Input. That option didn't exist.

 

The only option I had was to manually disconnect the last four wires and reconnect them one input above, followed by removing the last input by dragging the bottom edge upwards.

 

Having to manually disconnect and reconnect wires was a little disconcerting. I wondered: what would have happened if I had made a mistake with say the second input, instead of the third-last input? A lot more manual wiring would have had to be redone.

 

Notes

The Wire Multiple Objects Together QuickDrop tool (Ctrl + W) is extremely useful. However, at the moment it has the following limitation.

 

The other day I found myself writing code like the following.

Naturally I tried using the QuickDrop Ctrl + W tool. However, it produced the result seen below, which is not what I wanted.

The Ctrl + W tool wires each source wire to a compatible (coerceable) destination. In the example above it wires to I32 and DBL destinations indiscriminately.

 

The desired outcome would be achieved if the tool preferred wiring to destinations that match the source data type exactly, before considering other compatible (coercible) destinations. In the example above, the tool should prefer the DBL destinations. It should wire to the DBL destinations first, before considering I32 destinations.

Notes

  • The example above shows 10 wires being wired between the Index Array node and the Replace Array Subset node. The real-world VIs I was programming the other day required wiring multiple pairs of Index Array and Replace Array Subset nodes, some with as many as 30 wires between them. Wiring them manually was a tedious and time-consuming operation.
  • This idea is somewhat related to the following idea: Improvement to the QuickDrop Ctrl+W tool: Wire constant to multiple destinations
