password on labview 2009

[yves65]

hello, I would like to put a password on a Numeric Control, I wonder if this is possible. I use Labview 2009. Thank you in advance for your answers. best regards

Can you specify what exactly you mean by "putting password"? Do you mean that you want to allow the user to enter the value only based on correct password entered somewhere?

[yves65]

yes I do not want a person to enter without being authorized Thank you for your response

I think you should figure that out on a the application level not for a single control. But anyway, here is a quick example of what you ask. Password is 12345.

Where do you intend to save these passwords? Will these be hard-coded in the block diagram? If so, how will someone know what it is 5 years from now? Will they be saved as clear text? If so, where? If they're saved as clear text, then it's not secure since anybody can read the file. Will they be saved as encrypted files? If so, what kind of encryption do you intend to do?

The implementation of requiring a password on a control is only a small part of the problem.
