Detecting if running from a packed project library or from run time engine

[nanocyte]

I just noticed this post:

https://forums.ni.com/t5/LabVIEW/failure-of-conditional-structure-RTE-check-in-packed-library/td-p/3...

I've got two ideas:

• Check call chain (PPL)
• Check the application path (EXE)

Is there anything more direct?

I fail to understand what the problem is that you are trying to solve.  Are you trying to detect if code is in a PPL?  Or are you trying to get a path the a VI?

"Running from a packed project library" and "Running from run time engine" are not mutually exclusive.

You can use a PPL from RTE or development environment. 

So, PPL Y\N and RTE Y\N gives 4 combinations, and all 4 can happen.

The App.Kind Propery Node returns:

1. Development System
2. Run Time System
3. Student Edition
4. Embedded LabVIEW (includes RT)
5. Evaluation
6. Custom
7. (0) Invalid App Kind

Yes, that's correct. I was looking for something to let me distinguish the 4 possible states.

My call chain search to detect the PPL seems to be working but it felt very kludgey. and I was hoping someone had a more direct way.

Yes, that looks like a good way to get the RTE status. Thanks!

For the other property, this seems promising:

That is the property I use in my Class Factory to determine if I am using a PPL or not.  I am then getting the folder of the library/PPL in order to load up the desired class using a relative path (relative to the parent class's path).
