Control LED by parallel port program

Hello everyone..

I want to write a code which can light a LED bulb through a parallel port.
I don't have a big knowledge in c++ programming.
And very little knowledge in parallel port programming. :(

Can anyone help me out with this?

I'm using windows 7,Visual Studio 2010.Do i need any kind of driver to control the parallel port?
Can i get this work done by a USB port?
All i need is to light a LED (Basically output a voltage level high and low)

Thanks!!!

You can certainly do it over USB with something like a FT232, but you'll have to design a circuit for that.

For programming the parallel port, a good start is here.

I assume you know how to construct a circuit with a LED and resistor in series from a parallel port pin to earth. Bear in mind that drawing too much current from a parallel port pin is a good way to blow the parallel port.
