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.

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[1]
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

cleanupVisa

Example cleanupVisa=TRUE
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

defaultConPane

Example defaultConPane=4833
Description Sets the default Connector pane layout for new VIs
Datatype I32
Permitted Values
Default Value (4815)
LabVIEW Versions

8.x

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. [1]
Datatype Boolean
Permitted Values TRUE or FALSE
Default Value FALSE
LabVIEW Versions

OS's Supported

Notes

ExternalNodesEnabled

Example ExternalNodesEnabled=FALSE
Description Enables use of External Nodes
Datatype Boolean
Permitted Values TRUE or FALSE
Default Value 6.x?, 7.x: TRUE 8.x: FALSE
LabVIEW Versions

6.x? , 7.x , 8.x

OS's Supported

Notes None

ExternalNodeDebugging

Example ExternalNodeDebugging=FALSE
Description Shows External Nodes for what they are: sequence diagrams
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
Description Use hot menus
Datatype Boolean
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

MaxHelpDescLength

Example MaxHelpDescLength=8000
Description Maximum number of characters that will be displayed before truncation in the Context Help
Datatype Integer
Permitted Values
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

Example MRUFolders=TRUE
Description MRUFolders:Most recently used folders. Every time you select a file in a file dialog in LabVIEW, that location (folder) becomes the new top item in the location area (left side of the dialog) of the Windows file dialog.
Datatype Boolean
Permitted Values TRUE, FALSE
Default Value FALSE
LabVIEW Versions

8.2

OS's Supported

Notes

openInRun

Example openInRun=TRUE
Description When opening VIs in the development environment, open them in run mode
Datatype Boolean
Permitted Values TRUE or FALSE
