This is a list of LabVIEW ini File settings relating to the Execution System.

allowMultipleInstances

Example allowMultipleInstances=FALSE
Description Enables running multiple instances of the application at the same time.[1]
Datatype Boolean
Permitted Values TRUE or FALSE
Default Value FALSE
LabVIEW Versions

OS's Supported

Notes

ESys.StdNParallel

Example ESys.StdNParallel=5
Description Defines the number of threads to start in each execution system and priority level.
Datatype Integer
Permitted Values -1 to 8 (see notes)
Default Value 1
LabVIEW Versions

5.x , 6.x , 7.x , 8.x

OS's Supported

Notes
  • 0 is equivalent to turning off the Preferences menu item "Run with multiple threads"
  • 1 is the default value, equivalent to turning on "Run with multiple threads"
  • 2 to 8 defines a higher number of threads to start (i.e. a 5x5 matrix)
  • -1 tells LabVIEW to start with a custom set of threading parameters as defined by ESys.xxx.yyyy keys

hideRootWindow

Example hideRootWindow=FALSE
Description Hides the application's front panel window and removes any taskbar icons when running the executable.[2]
Datatype Boolean
Permitted Values TRUE or FALSE
Default Value FALSE
LabVIEW Versions

OS's Supported

Notes

runAsService

Example runAsService=True
Description This key tells the LabVIEW Run-Time Engine to ignore the Windows WM_ENDSESSION message that is sent when a user logs off! Use this key when your LabVIEW application is configured to run as a Windows service and has a user interface (service allowed to interact with desktop). The key prevents your LabVIEW application to quit when a user logs off.
Datatype Boolean
Permitted Values True or False
Default Value False
LabVIEW Versions

5.x , 6.x , 7.x , 8.x

OS's Supported

Notes See also following thread: Creating a Windows NT Service Using LabVIEW: [1]
