LabVIEW Task Manager is a debugging tool for use during LabVIEW code development. An expandable/collapsible tree diagram displays detailed information (both static and dynamic) on all VIs in memory, belonging to a selected project/target. It allows for interacting with single or multiple selected VIs at a time, and includes the following major features:

  • Selection of project/target
  • Lists all VIs in memory, grouped by class/library or disk folder, or a flat list
  • Searches for and enumerates clones in memory
  • DropIn VI for including dynamically referenced clones (Clone Beacon)
  • 'Refresh Now' (F5) re-reads all VIs in memory and adds new ones to the tree
  • Displays VI name, owning class/library, state, path, data size & code size
  • Displays VI FP Behavior, Reentrant?, Reentrancy Type, Paused? & Highlight?
  • Group by Class/Library or Folder, or display a Flat List
  • Sort by any column, ascending or descending
  • Filter out item types vi, ctl, and vit/ctt
  • Filter out vi.lib and global VIs
  • Filter out items from being displayed, per folder paths.
  • Tracking of, and ability to toggle, execution highlighting on multiple selected VIs
  • Tracking of paused VIs with ability to Pause/Resume/TogglePause multiple selected VIs
  • DropIn VI for pausing only while debugging
  • If a clone initiates a pause, a different pause symbol is used for all clones of that same reentrant original VI
  • Select multiple VIs and open or close their FPs or BDs
  • Double Click a VI from the tree to bring the BD (first choice) or FP to front, if already open
  • Select multiple top-level VIs and Abort them
  • Remotely close any VI's Front Panel

Installation and instructions:

Install this tool by using the VI Package Manager to install its associated package file (.vip). Installation requires VIPM 2014 or higher, which is available for free from jki.net (http://jki.net/vipm).

Known Issues:

  • Cannot abort SubVIs launched from remote VI Server or local Asynch Call By Ref

What's New in Version v2013.1.10.0   See changelog


What's New in LVTM v2013.1.10.0 since v1.7.0
(Starting with v2013.1.9.1, the first four digits denote the version year of LabVIEW that the version of this software is "saved for")

  • Rechecking for new app instances upon mouse over "App Instance" control
  • Do not limit multisection to siblings only
  • Do not allow selection of parent libraries
  • For "Clone VIs FG" made the "Add Calling VI" case the default case
  • Tree shortcut menu (right-click menu) several functions
  • Items not belonging to a parent library are now grouped in tree under "<no parent library>"
  • Relocated the LVTM "Regression Tests" VIs such that they are no longer excluded from view in LVTM by default
  • Many performance optimizations (including 'dependencies cache' per Neil Pate)
  • Do not create new template instances, and suppress loading dialogs (per xceric)
  • Persist the column sorting between refreshes
  • Persist the collapsed/expanded state of each library node in the tree, between refreshes
  • Persist the selected item between refreshes, if it still exists
  • New Help/About/Info dialog
  • License is now modified MIT
  • New icon
  • Several UI improvements
  • View can now be grouped by Class/Library or Folder, or display a Flat List
  • Added an ability to filter out items from being displayed, per folder paths.  Helps the user to de-clutter the view, and improves performance.
  • Added a progress bar for refresh
  • Persist some configuration settings between sessions
  • Several performance improvements
  • Added an ability to remotely close any VI's Front Panel.  Useful when a modal dialog prevents interacting with LabVIEW, including the LVTM window.
