Simple get and build

I am new to Cruise Control and would appreciate some help. I am trying to set 
up a simple nightly process that gets latest version from source control and 
the builds the solution. 

The application is built in .net and is comprised of an web application with 
several class libraries as sub projects. I need CC to get latest version of 
the both the web app and the sub projects...and then use the visual studio 
solution file to build the solution.

I have set it up to get latest of the web app and then build it, but I cannot 
figure out how to have it get latest code for the supporting class libraries.

This has got to be easy and I am probably overlooking something, but I have 
been through the documentation and haven't found an answer.

Any help would be appreciated.
