Can you add a password to a tolerance setting?

[JJRGT!]

My customer has a variety of inspections going on and has the ability to adjust the tolerances on the fly using controls.  But, he would like to add a password so only the supervisor could make the adjustment.  Is that possible?

Thanks,

Hi JJRGT,

There is no function that allows you to lock controls, however you can set up a password for the VI using File»VI Properties»Protection.  This allows you to lock the block diagram.  You could then set up the password using logic in LabVIEW. You could use a dialog box and if the input string doesn't match the string in the block diagram then the value would reset to the previous value.  That accomplishes the same thing.

Using a while loop you can constantly check for a string input. If the string input doesnt match that of a supervisor string then you can grey the tolerance settings and if it matches you enable editing....
