LabVIEW Documentation: Development Environment Event Callback VIs 
Development Environment Callback VIs are VIs that LabVIEW looks for and attempts to run when certain development environment events occur. Most of these are installed as part of the Dataloging and Supervisory Control Module (DSCM) and are used for starting and stoping the DSCM services that need to run along side LabVIEW. The lv_new.vi callback is used to LabVIEW the fancy new Tree View "New" Dialog that includes a template browser. OpenG makes use of these hooks for starting and stopping development environment application services that run in the background. For example the Auto Backup application. If you have the OpenG Package Manager and Development Tools installed you should not attempt to modify any of these callback VIs, but rather register your development application to recieve notification of these events using the appropriate OpenG resource API library.
