Presented at the Bay Area LabVIEW User Group on 02/07/2012. This is a second installment of the mini-series. The first part discussed using Dependency Inversion Design Principle and Dependency Injection Design Pattern in LabVIEW Development (09/06/2011).
Singleton presentation is in PowerPoint 2007 (.ppt), has a fair amount of animation and a few sound effects and is best viewed in Slide Show mode.
Zip file contains all examples (LabVIEW 2011), including NI Example code (for convenience) and links to their original location. LabVIEW 20(09/10/11) Singleton.lvproj example had been updated to include a code snippet (Singleton Design Pattern Conundrum.vi) showing it does not conform to definition of a Singleton Pattern (i.e. is not a Singleton ).
