so it doesn't have to do anything with the programming of the controller?

and far as i know, BLDC comes with 3 wires, two of which are positive, and remaining one is for ground..., if we change any of the wire, the motor may get burned... Undecided


As already said, its a three phase motor, all the three wires can be positive, ground or back-EMF sensing wires, it just depends in which phase the motor is at a given moment, just swap any two of then, believe me.

There is an excellent tutorial on how to control BLDC motors at;
http://www.atmel.com/dyn/resources/prod_documents/doc4987.pdf

The short answer is you can change direction with code or by swapping ant two wires as noted elsewhere in this thread.
