how to encapsulate subVI in LabVIEW?

[Jeff Wang]

We have some sub VIs and want to provide others to use, but we do not want them to open those VIs. Are there any methods to encapsulate those VIs such that people can only use it? Thanks.

I'm assuming by "open" you mean look at the block diagram. You can password-protect the VI. Or, you can create an application distribution to strip the block diagram. Note if you strip the block diagram then people who try to use them in a higher version of LabVIEW than the version you created them in will not be able to since LabVIEW cannot recompile the VI. Instructions for both are in the LabVIEW Help.

Thanks for your reply !!!!!

You mentioned "create an application distribution" , do you mean use Labview Application Builder Toolkit to creat it? Thanks.

Yes. The actual term is "source distribution". You can read more here.
