You can save the subVI(s) that you don't want to allow access without
diagrams, or with the diagrams password protected -- assuming you have
version 5 or greater. Use the Save with Options... File menu item.
A word of advice, saving without diagrams produces the smallest file, but
it means that the VI only works with compatible versions of LV because
LV no longer has access to the code to recompile it. Saving with
passwords allows LV to have access to the code to compile for version
and platform changes, but doesn't allow for diagram editing or viewing
unless given the password.
Use passwords wisely. If others will benefit from the subVI, the
y may
benefit much much more by having the ability to modify it to suite
their needs. You can place your name or usage information in the
VI description.
Also, users will still be able to double-click the icon to view the panel,
it is sort of the expanded version of the icon/connector.
