Add a Visible Item to the cluster container to enable the display of the currently selected AutoSizing style
Similar to the other Visible Items (enabled above on "source" string & "code" integer) like
For consistency with others similar above:
Sometimes when you hit the Cleanup button in a block diagram it doesn't work. There seem to be many reasons, complexity of the block diagram, certain objects make it fail, etc. This idea is not how to fix those failures, but when they do occur, the cleanup routine should give some response back to the user. A dialog explaining what is wrong, should be shown.
Currently if you hit cleanup and it is going to work, you get the spinning blue circle and it cleans up. If it doesn't you get NOTHING. As if your click wasn't registered. There should be some response.
When the abort button is pressed, and the development environment is present, the block diagram should be shown and the portion of code that was currently executing should be hilited.
I've been wondering for years now why the LV Save (& Save All) dialog is quite unusual in terms of its layout & usability.
Redesign the "Save Changes?" dialogin accordance with the standard dialog design criteria as follows.
When developing new VIs f the procedure is usually the following:
1. right-click class or desired location, new VI (static or dynamic dispatch template etc.)
2. Implement functionallity
3. Edit VI icon for easier recognition
4. Save VI
The problem here is that usually the icon allready contains the ideal name for the VI which means I am typing the name of the VI twice, once when editing the the icon and once when saving.
Would it not reduce the development-time by suggesting the name entered in the VI icon editing procedure as the user attempts to save the VI?
I'm currently expanding a large SA with 270 classes and on good days I implement 20-30 VIs and would find it nice if I were not forced to type the name twice.
Interested what experienced LV-users think of this suggestion!?
The title says it!
It is often confusing "Which is the opposite end in a queue?/What does opposite end mean?", esp for new user of LabVIEW.
Seems here, even the author of the LV Queue primitives was not able to recollect its name correctly.
Also, please see below from the LV Help.
In a comment to this suggestion: Paste from Excel to LabVIEW Arrays, I suggested what I am reposting here as a separate Idea, namely, offer the possibility to paste (or import) from the clipboard, wherever you can Export to Clipboard.
The Export to Clipboard shortcut menu is not without limitations. For instance, for graphs, here are a few I mentioned in the past:
Note that, as far as I can tell, the only thing we can so far export to the clipboard from LabVIEW are strings (see this suggestion to change that).
Therefore, this suggestion is to offer the same limited ability, i.e. import strings (spreadsheet formatted arrays, graphs, combox box array, etc) into objects with which they are compabible.
When working with User Events as an API between modules there is a nasty little thing which unfortunately keeps rearing its ugly head.
If we retrieve a cluster of User Events (or an Event registration refnum) from a module with events we should be listening to and wire this to an event structure we get a memory leak if not all events are handled. This particularly occurs whenever the API is extended and not all listeners have been updated.
It would be much easier to track down these kinds of problems if the Event Structure would display which User Events are in the associated Registration Refnum but are NOT yet handled. This would be a great too in tracking down rogue Events and eliminating possible memory leaks due to implementation errors.
Currently one has to iterate through ALL of the user events and observe the warning "this event is handled in another case" in order to find out if all have been handled or not.
I only mean that this should apply to the sub vi's that come with LabVIEW. I was putting together a vi that is execution time sensitive. I had a choice between the IMAQ Histogram and IMAQ Histograph. I could get the result i needed from wither one but I was forced to try each, run a few times, and clock each one. There are many such "which of these two similar options is fastest" choices we make for every program and knowing which upfront would be very helpful.
When doing code refactoring (or other improvements) we often run into the situation where we may want to replace constants for whatever reason.
Example: If we previously have only had support for 8 devices which (for reasons I won't try to defend here) ends up being hard-wired into the software and we now want to change the code to replace these constants with a Sub-VI we have a very hard job finding all of the instances of "8". I can search for a numeric constant but this produces so much noise it's useless. It it were possible to narrow down the search to the value "8" for a numeric constant thent he search would be much easier.
Same goes for paths, enums, error clusters and so on.
It’s amazing to send some questions about programing for labview. Recently, I use labview to develop an application which includes some file I/O function such as creating path to save some data. and I use subVI’s path cite to indicate new path for saving data. But unfortunately，I fund that it’s seriously problem after generate exe application and running。
Absolutely. It’s unavailable to save data. So I have to using top VI path to generate new path and solve this problem, during this time. I have an inspire to share with you during generating exe application using labview which has application self check security as show in next table.
Determining whether it’s security or unavailable after produce exe application when running
Auto change scroll position in table controller
If user set table controller number of page for displaying. it can automatically adjust scroll position in table controller when new page data incoming.
the input value of the conditional terminal should " pass through "
(like the "case selector" of the "Case Structure")
So, due to massive lag in the project environment, borked graphics drivers on the virtual machine and the resulting random rearrengement of objects on the front panels, i've Locked all objects.
Now, trying to delete a control from the block diagram nothing happens, which is technically correct. No information or warning, however, is borderline Bug in my book. I'd expect a popup "Object is locked", not just a silent denial.
LV2014SP1f3 (which for some reason is 184.108.40.206 instead of 14.1.3.x, but that is another discussion)
Right now the only way possible to set the tabbing order of controls on the front panel of a (sub)VI is to use Edit >> Set Tabbing Order.
I would like a VI Server property/method to be able to programmatically set the tabbing order of the controls on the front panel the way I want. This way I can write a script to fix a large number of VIs without needing to manually click through each one. (Of course I would be responsible for programmatically figuring out the order I wanted, but I could make some general assumptions like following the top-bottom left-right on the front panel existing layout, or following how they are connected to the connector pane, etc)
As the title says.
double click on a *.rsl file should open the Vi Analyzer results window
We have a CI server that runs VI Analyzer and posts the rsl files as artifacts, downloading the rsl file to my code base works great to find and fix errors. The only thing missing is the double click.
The Open/Create/Replace file I/O primitive is pretty powerful. It will check to see if the file is there for you, and, if not, create a new one. I use the "Open or Create" option often when generating multiple delimited text files in long term tests. When a new file is created, I need know so I can add a header, and I need to skip the header operation if the file is being appended. Sure, I could check to see if the file exists before trying to open it, but then wouldn't that just make the power of the Open/Replace/Create function redundant? Some operation took place based on my input to the "operation" terminal, and whether or not the file exists. Unfortunately, I have no idea what that operation was, because the function doesn't tell me. Let me know if the Open/Create/Replace function created a new file so I can add my header.
This is not without precedent. For example, the "Obtain Queue" primitive has an option to create a new queue if a queue of the given name is not found. It let's you know if the new queue was created:

Currently, we get a single line:
This results in this kind of mess courtesy of the IMAQ Load Image Dialog.vi):
To update the snapshot illustrating this other thread, here is an example of MS Word in action, illustrating the desired behavior:
In other words, it helps cleaning up the results, while using a single dialog window for all kinds of different files (which will be dealt with differently down the line).
I am not sure how multiplatform that can be, but here is the file open dialog options from TextWrangler on MacOS:
so it seems that can be done.
The thread I am referring to had a link to a Windows API call, but the link is dead (probably the result of the recent disastrous site cleanup). And of course is not multiplatform.
I have 208 data producing test stations, located in 10 different labs in 4 different countries.
I need an easy way to copy or move the files from the test stations, to a lab data computer, to a “web service” to a master global data base in the US.
Within each test lab I am thinking a network shared drive.
However, getting the files from China, Taiwan and Germany to the US automatically is challenging.
I am thinking that a web service like “amazon web services” would work. But setting it up and programming it into LabVIEW is more challenging than it should be.
It would be really nice if Nation Instruments would create a simple easy solution to do this.
When placing Icon Text inside a frame in the Icon Editor, there appears to be a rule that the text region is between the lowest two horizontal lines. I'm trying to design an icon with a two-line-width frame, with a lot of empty space in the middle, but this (deduced) rule stymies my efforts. I'd like to suggest that the algorithm be changed to place the Icon Text inside the largest blank space available.
Here is an illustration of the problem. All these images are a one-pixel Frame and a single line of text. In the first image, a single additional line is at the top, while in the second image, a single line is at the bottom. The final image pretty much precludes designing a Template with a two-pixel bottom border, something I'd very much like to do.
