Arduino to VB6 / VB2010

I have had a look but have been unable to find what I want.

I am completely new to interfacing the arduino to software, and require a bit of a dummies guide, some simple code to get me started.

Basically, I require a VB program to connect to the arduino, and read the value returned from an analog port.

I understand there is a MSCOMM component involved, however the only simple examples I can find are outputs, rather than inputs.

If someone could point me in the right direction (both VB code, and arduino), it'd be much appreciated!
