Multi-user login screen help

[MarknTX]

I am looking into an application front end with NI hardware controlling a temp process. The fun thing is the multi-user login that controls the screens you can access. Does anyone know of a good way to accomplish this?

Here is an example from NI's website which demonstrates how to do this. It's for one login in particular, but will give you the basic concept. Use an event structure to wait for the user to input their data and then check that before allowing access to your VI.

I cannot get the link to work, can you please send it to me or something?

Thanks,

I've attached it below. Here is the description from the webpage:

This VI uses Key Down events to control the user login process. The user must enter the username and password using only upper and lowercase letters. If the user enters other characters, the VI displays an error message and discards the event. The VI also converts all uppercase letters to lowercase before verifying the username and password in a subVI. "Number of loops" displays the number of times the While Loop iterates, which is the number of times an event occurs on the front panel.
