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.
