NI LabVIEW 2023 Q3 (23.5.0.49300–0+f148) with Drivers Win x86

LabVIEW 2023 Q3 - Date: July 2023
LabVIEW 2023 Q3 includes the following features and changes.

Diagram Zoom
- In LabVIEW 2023 Q3, you can zoom in or out when editing the block diagram of a VI using the View menu. Ctrl (Cmd on macOS) and the scroll wheel of the mouse can also be used to zoom in or out. A tip strip displays the zoom level percentage when zooming. To return to 100% zoom, use View>>Actual Size.
- When you first select View>Toggle Zoom from the menu, the diagram will zoom out to fill the entire window. LabVIEW will restore the zoom level to its previous value when the same menu command is used a second time, but the diagram will be centered around the current mouse position.
- New keyboard shortcuts include:
. View>Zoom In: Ctrl-+ (or Ctrl-=)
. View>Zoom out: Ctrl-
. View>Actual Size: Ctrl-0
. View>Toggle Zoom: F2

Double-click to Finish Wire
- In previous versions of LabVIEW, double-click on the diagram resulted in creating a wire branch. In LabVIEW 2023 Q3, you can use the double-click gesture to complete the wire and place a connected control or indicator after creating one end of the wire with a data type. Control modifier can be used to create a constant. Void wires will only create wire branches. Right-clicking while creating a wire will display a menu of options:
. Create Constant
. Create Control
. Create Indicator
. Create Wire Branch



Find All Instances When VI Running
- In LabVIEW 2023 Q3, you can right-click on a subVI on the diagram, or the icon of a VI (in the top-right corner of the VI window) and use the Find All Instances command even when the VI is running. In previous versions of LabVIEW, this command was only available for VIs in edit mode.
- In addition, the right-click menu on a subVI may now contain the following commands at run-time:
. Open Malleable VI Front Panel
. Open Front Panel
. Open Generic VI
. Open Polymorphic VI
. Show VI Hierarchy

Quick Change List
- In LabVIEW 2023 Q3, you can use the keyboard shortcut Ctrl-Space or the right-click shortcut Quick Change to display the Quick Change list when editing text in a free label. By selecting an item (such as Numeric), the label will change to that object type, and the label text will be converted to the object's value.
- You can also Edit>Paste Special command to paste text from the clipboard and immediately display the Quick Change list.
- You can also add custom plugins to the Quick Drop list. Refer to the instructions document in resource\dialog\QuickChange\plugins\.prefix_Template for more information.

Quick Change Palette
- In LabVIEW 2023 Q3, after defining a rectangular selection on the diagram (and before releasing the mouse to finish the selection), you can use the keyboard shortcut Ctrl-Space to display a palette of items (such as loops) that can be placed in the position of the selection. In addition, one of the palette items will create a subVI from the selection.



Execution Highlighting
- LabVIEW 2023 Q3 introduces Slow, Medium, Fast, and Very Fast options for the speed of Execution Highlighting. Medium speed matches the behavior of Execution Highlighting in the previous versions of LabVIEW.
- Click and hold the Execution Highlighting toolbar button to display a menu of speed options. In addition to improving the visibility of the executed code, the animation of execution is given a new visual treatment.

Building Applications and PPLs Improvements
- LabVIEW 2023 Q3 has improved cache behavior for packed project libraries and applications.
- The first build will populate the cache, and then the subsequent builds will be much faster.
Support for Apple Silicon
- LabVIEW 2023 Q3 for macOS runs natively on Apple Silicon. The LabVIEW executable is a universal binary.
Text Editing Shortcuts on macOS and Linux
- In LabVIEW 2023 Q3, macOS and Linux users can use the following Emacs-style editor keys when text fields are active:
Ctrl-A: Beginning of line; with Shift, select to beginning of line
Ctrl-E: End of line; with Shift, select to end of line
Ctrl-D: Delete character forward
Ctrl-F: Forward char; with Shift, extends selection
Ctrl-B: Backward char; with Shift, extends selection
Ctrl-K: Kill (cut) to end of line; supports append-to-pasteboard behavior for multiple consecutive Ctrl-Ks
Ctrl-N: Next line; with Shift, extends selection
Ctrl-P: Previous line; with Shift, extends selection
Ctrl-T: Transpose characters at cursor
Ctrl-W: Wipe region (cut selection)
Ctrl-Y: Yank (paste)
- By default, the Control and Alt (Meta) keys on Linux can be used interchangeably for menu shortcuts. When the text is active, the editor Control key bindings take precedence, but the Alt menu bindings remain active for menu shortcuts.
- On macOS, Cmd key menu shortcuts are not affected by this change.
- Ctrl-C, Ctrl-X, and Ctrl-V retain standard copy, cut, and paste behavior.
- Config token EnableEmacsTextEditingShortcuts=False can be used to disable text editing bindings.
Cluster Consolidation Behavior
- In LabVIEW 2023 Q3, clusters with the same type, but different cluster field names will be represented by different types in the built .NET Interop Assembly.
- In the previous versions of LabVIEW, clusters with the same type were represented by the same type in the .NET Interop Assembly irrespective of the cluster field names.
- To use the old behavior, add the following to the LabIVEW.ini file: DotNetAssemblyGeneration.UseClusterFieldNames=False

2262038 File Dialog Does Not Support Some Patterns That Worked in Earlier Versions
The File Dialog no longer works with NULL characters in the Pattern input to present multiple filters. This change in behavior can affect applications that were built with the option "Allow future version of LV Runtime to run the application."
Workaround: There is currently no known workaround for this issue.

2263807 Activate Button Does Not Work in LabVIEW Evaluation Reminder Dialog
Workaround: Use Help>Activate LabVIEW Components from the LabVIEW menu or run the NI License Manager.

2342514 Open Venv Python Session.vi Does Not Work For Paths With Spaces
Open Virtual Environment Session.vi with the Open Venv Python Session configuration returns error 1671 ("Error creating python session") if the Env path contains any spaces.
Workaround: Create a directory hard symlink via mklink /J that does not contain spaces and use that path in LabVIEW.

LabVIEW (Laboratory Virtual Instrument Engineering Workbench)is a graphical programming language that uses icons instead of lines of text to create applications. In contrast to text-based programming languages that use instructions to determine the order of program execution, LabVIEW uses dataflow programming. In data flow programming, the flow of data through the nodes on the block diagram determines the execution order of the VIs and functions. VIs, or virtual instruments, are LabVIEW programs that imitate physical instruments. In LabVIEW, you build a user interface by using a set of tools and objects. The user interface is known as the front panel. After you build the front panel, you add code using graphical representations of functions to control the front panel objects. You add this graphical code, also known as G code or block diagram code, to the block diagram. The block diagram somewhat resembles a flowchart. The block diagram, front panel, and graphical representations of code compose a VI.

What is LabVIEW?

LabVIEW simplifies the hardware integration for engineering applications so that you can rapidly acquire and visualize data sets from virtually any I/O device, whether by NI or a third-party, using a consistent approach. Combined with a graphical programming syntax that reduces the time to visualize, create, and code engineering systems, LabVIEW - with a community of over 300,000 developers - has proven to be unmatched in helping to rapidly turn ideas into innovations.
Since 1976,National Instrumentshas equipped engineers and scientists with tools that accelerate productivity, innovation and discovery. NI's graphical system design approach to engineering provides an integrated software and hardware platform that speeds the development of any system needing measurement and control.
