Do you have an idea for LabVIEW NXG?
Use the in-product feedback feature to tell us what we’re doing well and what we can improve. NI R&D monitors feedback submissions and evaluates them for upcoming LabVIEW NXG releases. Tell us what you think!
If creating a reference to a .Net control you will observe that is reference type of ActiveXContainer is created which is sometimes confusing at a first sight.
Please introduce a .NetContainer (at least cosmetically at block diagram) for a better overview. If you are doing so, you could change as well the color of the ActiveX container with respect to the .Net container on the block diagram. If you have to change the programming interface, it would be much easier to spot where you have to do so.
One of the most over-looked LabVIEW VI Properties, mentioned in all of the "Good LabVIEW Coding Practices", is the one called "Documentation", where you describe what the VI does, and its Inputs and Outputs (at a minimum). [NI Examples are certainly guilty of this].
I've been trying (and mostly succeeding) to ensure that every VI I write has such Documentation. Sometimes I make a mis-type, highlight "bad" parts, and hit the "Delete" (or backspace), then say "Oops, erased too much, let's undo that with ^Z". Except there is no Undo, or at least it isn't bound to ^Z here.
I can find no other place in LabVIEW that doesn't allow ^Z to replace deleted text. It works in String Constants, in Labels (whether Free Labels or names for Controls/Indicators), and other places.
To encourage LabVIEW Developers to use the Documentation property, can you please allow us to "undo a boo-boo" with ^Z?
When you navigate through Labview code and go deeper in VIs hierarchy you end up with dozens windows open on your monitor. Lets create special action for opening subVI (like existent Ctrl+RightDoubleClick) which will close FronPanel BlockDiagram of VI from which you open new one ?
Title basically says it all but I'll elaborate. With increasing monitor resolution, a 16x16 glyph on a listbox doesn't work very well. On a 4K monitor this is awful tiny. This idea is to support larger glyphs in Listboxes, Multi-column Listboxes, and Trees. Glyphs are used in several places but on favorite of mine is to have item selection with checkboxes,example here. Allowing for these glyphs to grow with the row height would make them appear more cohesive. There is a threaddiscussing this topic, and a work around involving an array of picture rings that is placed over the listbox control. Here is a demo from that thread:
This work around is fine for simple things but doesn't scale well, and doesn't support trees easily. I for instance want to have two trees, where a user can drag and drop from one to the other with the larger glyphs coming along with the drop. Having to handle where the user dropped, and then dynamically building the glyphs to overlay on top of the tree, with indentation, and hiding when a tree's leaf is closedis a major pain. Please NI add a feature allowing for larger glyphs, and I would be so happy.
Currently to AutoScale an axis once, you need to set the ScaleFitX/Y property to 1. However this is really just like calling a method since the value of the ScaleFit property remains whatever it was previously. As a result, I find this mechanism unintuitive and would prefer to use the invoke node to call a suitable method named ScaleFitX/Y since it is an operation that just happens at a moment in time rather than changing a property.
Current Method: Property NodeProposed Idea: Invoke Node
Sometimes the order of the frames have to be changed in order for a VIM to work properly. It would be very useful if we could either rename the case itself or at least show the subdiagram label in the rearrange dialogue box.
Actually allow to add text in the frame case name would be much better and also help to navigate around when there is a lot of frames. All the frames are either ignored, declined and one accepted.
I just ran into a situation today where I had a case structure with approximately 64 frames in it, 48 of which I wanted to remove.
The method of right-click the selector, select "Remove Case" (This step is right beside the "Insert Case" which is frustrating), repeat 48 times while the mouse is wandering all over the screen between the case selector and the menu selection..... cue carpal tunnel problems.
I really wished I could just either use the "delete" and "insert" buttons to mimic the appropriate menu selections
Be able to select multiple cases from the "Rearrange cases" window and select "Delete".
Error in terminals that are ignored/passed through by the VI without preventing normal execution should be marked differently in my opinion.
I've lost count of the times where I have to keep reading through the help files to check a function's error in behavior.
Examples: Release Semaphore, Close reference, Release Notifier
Then there're the functions that I have created that exhibit the same behaviour. People reading won't be able to tell at a glance if the error prevents execution when called from another function. As a quick fix I label the terminal 'error in (pass through)' or 'error in (ignored)', but it's not ideal.
Bonus points if this can be marked as such during development and the behaviour enforced/checked at compile time similar to the following (I know it will be difficult to reliably implement, so maybe warn instead):
When a 1 Dimensional array of any type is showing only a single element, LabVIEW forces a horizontal scrollbar. I couldn't find any documentation or reasoning behind it. It's really annoying and ruins UI design that Vertical is the normal scrolling direction for just about everything else ever and LV messes that up for some seemingly arbitrary reason.
LabVIEW scripting makes it possible to automate repetitive tasks in LabVIEW, but it is often difficult to find the properties and invoke nodes to accomplish the task. It would be great to have a recording feature that watches what you do in LabVIEW, and then generates the corresponding code for it. I'm sure the engineers at NI could design it much better than any more specific ideas I could throw out, so I will leave the rest up to them.
One of the fiddly things I seem to do more than I'd like is adjust the bottom of block diagram comments to the right height. At a minimum there, but also for similar text boxes on the front panel or subdiagram labels, etc. I'd like to have a snap feature that sizes to a multiple of the text height. Examples:
