Password protected page(s), switch between pages

[P.Rayne]

hello all,

is there a way that one could protect access to page(s), switching
between pages, which are password protected. 2 levels of
protection...user and admin. the admin has access to all pages where
as the user may access only certain pages.

can one link pages together so as to move back and forth between pages
to view diff. data ?

i know that there is a feature that allows the VI to be password
protected prevent viewing block-diagram), but this doesn't disallow
the person from using the page, i,e accessing the information by
running it.

any ideas and or points of reference are welcome,

thank you,
cheers,

Are you talking about different pages of the tab control? You can individually enable/disable/disable & grey out pages of a tab control. Use Property:Pages to get an array of references to the tab's pages and then you can use the Index Array to get a specific page reference. The property Page Enabled State can then be used. You would have to add your own code for password checking and entry but I think I remember seeing some examples posted for doing that. Try doing a search of the forum.

P.Rayne;

There is an example at NI on how to use Passwords to Control Access to a VI. It shows what Dennis suggested: use Property Nodes.

I made a modified version of that same example using biometrics, specifically fingerprints, including an identification mode example (meaning that by just presenting the biometric, the system identifies you and gives you access based on the privileges associated to your identity.)
