====== Application Builder ======

//For more information, see [[https://www.ni.com/en-us/shop/software/products/labview-application-builder-module.html]].//

The LabVIEW Application Builder Module provides tools for exporting LabVIEW code in various forms. The most common ones are stand-alone, end-use applications and source code exports.

===== .exe File Structure =====

When generating executable files, the Application Builder can generate a .zip archive next to the build's .exe that will contain the internal folder structure of the executable.

This undocumented feature can be enabled with

    NI_AppBuilder_KeepInternalLLB=True

---- 

===== AB API =====

It is possible to programmatically build and configure build specifications using the Application Builder API. This API can be found on the Function Palette under Programming » Application Control » Application Builder. 

==== Problems ====

**Problem**: When using the AB API to build an exe containing a web service or a DLL, LV will throw an error:

**Fix** (courtesy of Olivier Jourdan): Make the following functions reentrant:

  - ''vi.lib\AppBuilder\AB_API\RESTful\Build.vi''
  - ''vi.lib\AppBuilder\AB_API\DLL\Build.vi''
