Simple Plugin Example

Here is the simple packed project library plugin example we walked through during tonights meeting.  I will try to get more details up on the workflow shortly...

Hi John:

Here I am wrestling with an app that’s just screaming for a plug-in architecture, and it looks like I was forced to bail on the very LUG meeting that I probably needed to sit in on. Rats! FYI, I appreciate your hard work on behalf of the LUG. Sorry to have missed this one.

Here is a literature review of sorts on PPL's as plugins:

Plugin Architecture Using PPL's: https://decibel.ni.com/content/docs/DOC-19176

Plugin Architecture Using Classes and PPL's: https://decibel.ni.com/content/docs/DOC-33364

Plugin Architecture Using the Actor Framework and PPL's: https://decibel.ni.com/content/thread/12998?start=15&tstart=0

To PPL or not to PPL: http://labviewjournal.com/2011/07/to-ppl-packed-project-libraries-or-not-to-ppl-part-1/

Create Single-File Object-Oriented Plugins for use with a LabVIEW Executable: https://ekerry.wordpress.com/2012/01/24/created-single-file-object-oriented-plugins-for-use-with-a-l...

These are great resources for getting up and running with ppl's as plugins.  I have also had a good amount of success with PPL's as plugins in a large Actor Framework application and will do my best to answer any questions.  One thing I will mention is that following the SOLID principles of OOD is more or less a requirement to developing large LVOOP componentized (plugin based) applications.  The dependency inversion principle is your friend.
