Advanced

The application builder has several interesting advanced uses

Automatic building

You can use a VI inside vi.lib that can build without user interaction. The VI is located in <vi.lib>\AppBuilder\BuildTargetBuildSpecification.vi. This VI takes a project path and optionally a build and target name as parameters.

Symbolic paths

Inside the application builder LabVIEW uses several symbolic paths to have envorinment dependent variables.

Symbolic path	Contents	Usage
NI_AB_PROJECTNAME	Name of the project	Automatically place the build in a folder that is named after the project
NI_AB_TARGETNAME	Name of the (Real-Time) target
