LabVIEW
please help: password protected GUI
smercurio_fc, see now you are following me around.... 😮 (Beat you by a few minutes on the other tread).
I think the question is not about passwording the diagram, but a UI choice where certain parts are only shown after entering a password. For example, there might be data for the operator and there might be extra data or controls only of interest to the engineer. The display should change depending on the privileges of the current user.

Yeah, I was kind of amused after I posted my response since I hadn't seen your post in the other thread. I was interrupted while creating mine, so that probably accounts for the time difference. So effectively, a circular reference was created. I wonder if that will blow up the boards. 
I have to congratulate you on discerning what the user was asking for. I was certainly confused, probably because I was looking at the VI and not being able to understand what was trying to be done. Your guess seems to make sense.

Please open the example finder on LabVIEW and look for an example called "login dialog". It shows you how to authenticate a user. Modify it as needed for your specific purpose. Now you would just create two VI states, and select one depending on the outcome of the password entry.
You can show or hide any object on the front panel using property nodes with the "visible?" property.
Alternatively, you could e.g. use a tab control (with hidden tabs) and show appropriate panel depending on the user state.
See how far you get. 🙂
