LabVIEW configuration file/Miscellaneous

This is a list of Miscellaneous LabVIEW ini File settings.

ActiveXMoreContainerOptions

Example	ActiveXMoreContainerOptions=FALSE
Description	Adds "Persist State To Edit Mode" and "Destroy And Recreate When Run" to the Advanced submenu of an ActiveX container
Datatype	Boolean
Permitted Values	TRUE or FALSE
Default Value	FALSE
LabVIEW Versions
OS's Supported
Notes

BldApp.RemovePolyVIsandTypedefs

Example	BldApp.RemovePolyVIsandTypedefs=FALSE
Description	Setting this to FALSE stops the LabVIEW Application Builder from aggressively removing polymorphic VIs and typedefs that it thinks are not required
Datatype	Boolean
Permitted Values	TRUE or FALSE
Default Value	TRUE
LabVIEW Versions	7.x
OS's Supported
Notes	By default, the LabVIEW 7.x Application Builder does not include type definitions and unused instances of polymorphic VIs into executable in order to decrease size of application. This setting can be changed in the LabVIEW 7.1 applciation Builder in the Application Settings page. If a VI in your build calls an external VI that uses a type definition in order to pass parameters, and the AppBuilder is unaware of this external VI, it will end in tears. Also there is one other issue which makes this setting very important. In LabVIEW 7.x, by disconnecting typedefs from controls they did loose their default data and return to LabVIEWs default default data. This could be a major problem if you used strict typedefed clusters on front panels to provide certain default data when unwired and those default data did not match LabVIEWs default default data. This has been mostly fixed in newer LabVIEW versions from 8.0 on.

coerceFromVariant

Example	coerceFromVariant=TRUE
Description	Force variants to automatically coerce to any data type that they are connected to
Datatype	Boolean
Permitted Values	TRUE or FALSE
Default Value	FALSE
LabVIEW Versions	7.x , 8.x
OS's Supported
Notes	Tread carefully, as using this function removes coercion notification, and does not use error handling

Description	Automatically close VISA sessions - do not require the use of the VISA Close VI
Datatype	Boolean
Permitted Values	TRUE or FALSE
Default Value	FALSE
LabVIEW Versions	5.x , 6.x , 7.x , 8.x
OS's Supported
Notes	None

OS's Supported
Notes	None

dropThroughClicks

Example	dropThroughClicks=FALSE
Description	Allow drop-through clicks
Datatype	Integer
Permitted Values	TRUE or FALSE
Default Value	TRUE
LabVIEW Versions	4.x , 5.x , 6.x , 7.x , 8.x
OS's Supported
Notes	None

EnableStrictTypedefConstantConfiguration

Example	EnableStrictTypedefConstantConfiguration=FALSE
Description	Adds a new context menu item to constants based on strict typedefs called Act as Strict Typedef Constant.
Datatype	Boolean
Permitted Values	TRUE or FALSE
Default Value	FALSE

OS's Supported
Notes

Datatype	Boolean
Permitted Values	TRUE or FALSE
Default Value	FALSE
LabVIEW Versions	7.x , 8.x
OS's Supported
Notes	None

GenericsAreGo

Example	GenericsAreGo=TRUE
Description	Adds a context-menu item to controls and indicators labeled "Generic". This activates an abandoned feature in LabVIEW enabling the creation of "Generic VIs". If a control marked "generic" is connected to a VI's connector pane, it will automatically change to whatever type is wired to it; an indicator marked "generic" shows similar behavior with its block diagram terminal. If this just sounds like Malleable VIs with extra steps, that's because this is an unfinished prototype of what eventually became that. Using them is a BAD IDEA, unless you just want to experiment with it as a curiosity. NI staff have warned against using this in any kind of production code, as it is very buggy, abandoned for a reason, and can corrupt VI's. Use Malleable VI's instead; they do the same thing much better without using buggy unfinished features.
Datatype	Boolean
Permitted Values	TRUE or FALSE
Default Value	FALSE
LabVIEW Versions	2014
OS's Supported
Notes	None

hotMenus

Example	hotMenus=FALSE

Default Value	8000
LabVIEW Versions	8.x
OS's Supported
Notes	If set to a non-positive number, then there will be no max. If set to 50 or less, then 50 will be the max

MRUFolders
