Published in January 2013, this is the official directive on closing references: when you need to and when you don't. http://www.ni.com/white-paper/14393/en In your picture, the code shown is fine. Moving the Open and Close inside the loop would just create a performance burden. Moving only the Close inside would cause run time errors since the reference would be closed on the second iteration.

I could use some help from the experts in understanding this. When defining classes is most other languages, you simply use the language itself to specify class behavior. In LV, there's this meta-language of project and dialog, with underlying xml, before you can get to an actual instance. It's... aggravating. The G language is certainly capable of representing the concepts in a class definition. Why isn't there a "class definition" VI?

About a year and a half ago I submitted a simple script based VI to create a cluster based on a DB table to the NI Community forums. https://decibel.ni.com/content/docs/DOC-19512 It looks like you went the extra steps of enumerating the column names and creating the CRUD polymorphics. This sounds like a great tool for someone who is not a DB expert but needs to quickly interface to an existing DB. The only question/issue I see would be if the DB changes, how does the user update the generated VIs?

Hi This is happening because of objects. There has been a discussion on the NI-site and Steven mentioned not to use typedefs in objects. I hesitated to do this but when thinking along I accepted that typedefs are not necessary in objects. In fact the object itself is the typedefinition. I now only use typedefs when interfacing to an object but not in the object definition itself and no problems anymore. I beleive I had this problem in five different situations and getting it fixed took a lot of editing. I don't say it is a bug and indeed should be solved but for now I can live with it because indeed a typedef is not necessary in an object.
