For whatever reason, the end of an array is just as natural a location as its beginning. Go figure...

Hence it would be nice to have an index array function that could be started from the end (for instance with an "invert" indexing option accessible with a right-click).

At this point, one has to either flip over the array (time and memory costly) or clutter the diagram with a "Array Size" + "Minus One" (and more if one wants to access previous elements).

My 2 cts,

X.

On occasion one needs to open the source code for a closed VI. The Project explorer window appears to be a good access point for browing and opening VIs. However, clicking on the VIs opens the front panel only. It would be great to have the ability to open the block diagram if one holds the <CTL> key while clicking a VI on the project explorer window.

I think it would be great to allow zooming out on a block diagram. I know we should make all attempts to code on the available window space without scrolling but it's not practical in some situations.

All the time I make type def enum's in order to use with a state machine. Most of the time I create the enum from the block diagram instead of the fp. Maybe I should change my habit but I wish there was a "create type def" option on the bd right click menu so I didnt have to change to control, switch to fp, customize, then change back to constant.

Enable a Sub VI to launch as a daemon without having to open a reference to it using its path.  The VI Properties page would look like this:

 

21429iB830C4B88A795136

Wait until done would be checked by default, and auto dispose reference would be left false be default.  So instead of parsing the path to the VI on disk and using a method to run it:

21433i0CFC0F873277247C

I just set the correct properties in the VI Properties page and drop the subVI on the block diagram of the calling VI.

In their current form, Auto-Indexing tunnels only operate on a single dimension of an array.  For example.  If you input a 2D array, through an auto indexing tunnel into a for loop, and display the resulting 1D array in an indicator inside the for loop as below, you will always get the last row.

 

I'd like to see a feature where you can right-click on the tunnel or something, and set it to auto-index by column, instead of by row, and get the last column instead.20773i86B483107F51CD3820775i651136B201680B64

 

It could be as simple as an option in the context menu for the auto-indexing tunnel to say "Index by rows" or "Index by columns"  It gets more complex with 3D 4D and moreD arrays, but you could do something like a submenu flyout that says "Index By Dimension" > "1", "2", "3" etc

I often use strict type definitions to change data between SubVIs. The wires of the type definitions are always pink and this is sometimes a little color chaos.

Strings are pink, clusters are pink, ...

 

It would be nice to have the feature like in the LabVIEW classes. There you can definie the look of the private variables wire (form and color).

A lot of the vi icons I make only have text inside a box. It would be neat if the text could be inserted in the icon from the name of the vi, without me having to type it in. Of course you have to name the vi in such a way that it all fits in the icon.

 

Also, this function should be optional, so if you wanted to make a glitzy icon, you could, just as we can now.

Hello!

 

What I really would like to se implemented as a future feature is a 'Search 1D Array.vi' with the option to do a case insensitive search.

 

Usually I just plug a "to upper case" vi on both array and search string inputs. It would be nice to be able to select it right on the vi instead.

 

The functionality should work as with the case insensitive match in the case structure.

 

 

Cheers!

It would be beneficial if nodes had the ability to retain data from their previous execution. Along with "Use Default If Unwired" it would save memory allocation and coding time if there was a "Use Current Value If Unwired" selection which would retain the node's value and pass the last executed value.

This figure illustrates one application where "Use Current Value If Unwired" would save memory and increase performance instead of using multiple property nodes or local variables for retaining the output data. It would also eliminate extra wiring in every case this node is not used.

I think there should be a way to reinitialize a stacked shift register to the originally initialized value so you can clear out the contents of every iteration all at once.  For example, the code below, implemented with 4 individual shift registers:

Could be implemented with 1 stacked shift register with a reinitialize terminal:

I use a number of file and libraries common to all my applications.
To lighten the display would be nice to exclude certain folder from VI Hierarchy

Populating values to the "enum" control is not possible by using the "strings" property node and hence to populate a large data to a "enum" one has to create a "Ring" control use the "strings" property and replace that "ring" with the enum (or if you have enough time enter them manually) .

 

So why not use the "Strings" property of "Enum" to write values to it directly..See the image attached

I miss the possibility to 

 

- add COM compatibility to .NET Interop Assembly builds

- add COM  compatibility to Shared DLL builds

 

 

I missed LV help information about the need to add a key file (*.snk) to the project first, before you can select it for signing the assembly. Unless you do that the file filter (*.snk) seems to fail when browsing.

parameter_system.jpg

In large application there are huge amount of parameters. If there is a lot of parameters usually there is also lot of parameter handling code in block diagram. This code can be moved to away if there is ready mayde parameter handling system. Here are my basic needs\ideas to this kind of system: 

 

- Parameter values are read from e.g. CSV-file when there is a first call 

- Parameter value must be changeable during code execution

- When value is changed new value must be updated to e.g. CSV-file

- User can change parameter name from project view. The new name is updated to all block diagrams (compare to shared variables)

- New parameters can be created from project view

- All parameter values can be changed and read from block diagram by using proper VIs

- Parameter library settings e.g CSV-file format and name can be set in project view

 

Is there any one else who needs this kind of system?
