Scripting: Check if LVLIB or LVCLASS was modified

[_Y_]

These properties shows if a VI was modified but not saved:

(at least, I believe so:)

Is there a way to check if LVLIB of LVCLASS was modified? I cannot find corresponding properties.

Thank you

Maybe out can use the class's version. It's automatically updated when the interface is changes. Not sure exactly when this happens, but at least when changing scope of vi's. You'll probably have to check all individual vi's as well. The class and it's vi's are separate entities.

Thank you for replies.

wiebe@CARYA,  I can check individual VI-s in LVLIB (or class) but I cannot find a way to check the library. For example was a VI added or removed? I do not think that reading of the version could help because previous version is unknown.

paul_cardinale, I tried your suggestion. It does not work for me. This is the code:

 

The result is always False despite unsaved changes in number of VI-s belonging to libraries and despite to changes in FP and/or BD of these VI-s.

What do I do wrong?

I found solution. At least, I believe so. There property Modifications Bit Set is equal to zero only if the LVLIB has been saved and not modified after that. Different non-zero values probably indicate character of non-saved changes but it is not important for me now.

It does not reflect changes of library members, so the library member must be questioned one by one.

How do you reach the Library properties in the diagram editor? I can't find any of Mods, HasEditsInThisContext or HasEditsInAnotherContext. According to http://digital.ni.com/public.nsf/allkb/2FF365A6FAB7B34786257ACD004BA15A, brown color in the property node means properties are internal or private. Is there a way to enable them?

[paul_cardinale]

It's one of the items in the first set.

Note: Never use private properties or methods in deployable code.

Thank you, these secret settings made the properties available for me.
