There is a help file for describe the vi(in LabVIEW 2018\vi.lib),It's a pity don't know how to get the useful vi to finish job.

[RavensFan]

Are you asking a question?  Or making a statement?

[weschen]

making a statement, because i don't know the vi list and help.

[altenbach]

Vis in vi.lib are described in the LabVIEW help. They are all  useful! Are you looking at anything specific? What "job" is there to finish?

[weschen]

there are many llb file under path(eg:LabVIEW 2011\vi.lib\Utility\printvi.llb),how to find the vi in the block diagram function palette(I know most of all can be found in the function palette).

[altenbach · Accepted solution]

All top-level tools are in the palettes, but some utilize helper subvis also located in VI.lib that are not meant to be used directly (they may be undocumented or can change functionality in future versions, so there is risk involved).
