This program is provided in the "Behaviors" section of LabVIEW 2010.  It can be very useful in more advanced projects, such as creating an NXT Trolley (a vehicle that follows a line, and stops with touch or sound.)

This program takes sensor values and graphs them on the front panel.

In this example, the NXT uses the values of the light and ultrasonic sensors to power the motor.

This example demonstrates how to use multiple sensors and motors to control a vehicle.  The while loops and case structures control the movement of the car.  The purpose of the nested while loops is to permit holding down the buttons.
