With a case structure I can place the mouse cursor over the structure and Ctrl + scroll wheel to cycle through the cases without it being active. If I try doing this on arrays it doesn't work.

 

For front panel arrays the numeric indicator must have focus for this to work. Doesn't work when the array data is selected. I understand that multidimensional arrays would be a problem, but for 1D arrays it would be nice if it cycled through the elements.

 

For array constant block diagram elements, no scroll action works regardless of what is active. Again it should allow the user to cycle through elements for 1D arrays simply by hovering over the item and Ctrl + scroll wheel.

Make it easier to find the right product in the uninstaller

If you install a lot of National Instruments developer tools the uninstaller becomes very crowded. You can have 50-100 components, often with similar names and varying name structure. Finding the component you want to uninstall/modify/repair can be difficult. 

 

The fact that things a split into so many separate components is practical, but the components should be organized better:

They could be:

  • logically grouped
  • have descriptions
  • there could be a search/filter function available (that accepts wildcards)

Allow us to specify a new source location

If I want to repair or modify an installation it might turn out that the original source for the installation is gone, or I have a new (identical/compatible) source that I would like to use instead. It would be nice if the uninstaller handled this, instead of insisting on the original. 

 

Currently there is a method for setting the control value of another VI via the Control Value Set Method. But there is no set with signaling method which allows control of VI's which react to changes on front panel controls. This makes it hard to automate VI's that are using front panel control events. There is a tedious work around to get references to control on the front panel and then use value signaling method . It would be very useful to just have one additonal method that does the signaling in additon to setting the value of the control.

 

 

Currently, the only object that we have access to in an Event Structure it the control itself:

This is not what I am interested in, most of the case, when I am working on the BD.

Rather, I'd like to either find the terminal, or local variables, references, etc.

Moreover, going to the control using the above shortcut may result in a messed up FP, not mentioning cases like this:

 

Screen Shot 2016-04-30 at 11.42.46.png

where the control may be hidden or invisible because it is in another tab than the one currently selected.

 

Now, I know that some will argue that the control terminal is most of the time in the event structure (see for instance this thread)...

But read the thread's comments for counter arguments: we would be talking about the Value Change event, but this is not what I am talking aboutin general: any event for that control should give access to the control's terminal (and BTW, it could very well be an indicator) and, as for a terminal, to this list of related objects:

Add a Visible Item to the cluster container to enable the display of the currently selected AutoSizing style

 

ClusterAutosizingVisibleStyle.png

 

Similar to the other Visible Items (enabled above on "source" string & "code" integer) like

  • "Radix" for a numeric integer (d-Decimal, o-Octal, x-Hex, b-Binary, p-SI Display)
  • "Display Style" for a string (n-Normal, \-\ codes, x-Hexadecimal, p-Password)

For consistency with others similar above:

  • also available on Block Diagram cluster constants
  • Visibility only selectable in edit mode
  • If Style is visible, it is changable in BOTH edit AND run modes

 

 

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.

 

  • Resize the dialog to be somewhat bigger than now.
  • Place the Apply same action checkbox & the Affected items list at the top half of the dialog. Remove these items from the tabbing list, so the user can easily tab among the other 3 buttons, with Save highlighted by default.
  • The Affected items list is not sorted properly, but in the Explain Changes dialog, it seems the VI List is alphabatically sorted. So when you select a VI in  the Affected Items list & click the "List unsaved changes..." hyperlink-like text, the selections are confusing to the user. PFB snapshot.

  • Additionally, the selection in the Affected Items list is not actually a selection, but looks like only a marquee. It gives a false impression that the selected item can be edited. Fix this.
  • Make the Affected Items list to be vertically scrollable, instead of the current horizontally scrollable style, which is highly cumbersome.
  • Change the "List unsaved changes..." hyperlink-like text into a button that is prominently visible. New users think that this would open a web browser.
  • Place the Save (All), Defer Decision / Don't Save (All) & Cancel buttons at the bottm right of the dialog in a horizontal fashion.
  • Add the Help button, like in many other dialogs in LV.
  • Keep the name of the dialog to be consistent - "Save changes before closing?", instead of like "Save changes? (Close Project)" - The Close Project text is misleading.

 

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. Smiley Frustrated

 

Seems here, even the author of the LV Queue primitives was not able to recollect its name correctly. Smiley Wink

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.

 

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 14.0.1.3 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)

It would be handy to have possibility to expand the index block to start from -1 or 1.

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:

As requested by this fellow 8 years ago: http://forums.ni.com/t5/LabVIEW/Multiple-pattern-lines-in-path-s-Browse-Option/m-p/776968/highlight/true#M355522, it would simplify some GUI if the user could select from a drop-down list, which files to look for in a File Dialog pop-up window.

Currently, we get a single line:

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:

 

Screen Shot 2016-04-11 at 18.30.21.png

 

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.

If an error occurred inside a case/event structure, it should include the case/event name in the error source for easy tracking.

It'll save tons of time for large applications with a lot of cases in the process loop.

 

I know I can do it myself.  Just something better to have with a right click.

Am I the only one that get forever waits when this dialog shows up? LabVIEW hangs "eternally" in this dialog and only way to keep working is to kill LabVIEW hard.

 

I need a button that skips the resetting so that I can go back to my code without having to restart LabVIEW!

Currently I use LabView through a Windows VirtualBox on a Linux Mint machine. I was told by a customer support employee that I should bring this idea to this forum. I chose this method because of the limited support for Linux even with the supported distro discs. I encourage NI to expand their Linux-compatible software to have the full capabilities that the Windows and Mac versions do for the distros that are currently out, and to expand the number of distros supported. Linux Mint is one of the most widely used flavors, and yet there is no support from NI.

How often do you find the need to orginize data into a table format while documenting your vi?  I for one, could & would use it all the time!  Creating a resizable table free label we all use in word & excel seems like a simple task and would aid in organizing and documenting data into a more readable format.  A ctrl+double-click or shift+double-click could serve as an easy access method, tab through the contents, and resize rows and colulmns vis a cursor change while hovering at the specific borders.  Free Label, New type, table format, organize data, rows, columns.

Idea:

Double-click to a wire + holding <ctrl> or <alt> will call the wire-cleanup tool for this particular line => much faster than via context menu
