Vista - regional settings details

Hi,

In order to try and resolve a problem with an application, I want to
query a system for it's regional settings. Specifically, I am
interested in the thousand-thingie and decimal separator.

The problem I am encountering is that they are occasionally set to the
same character, creating havoc, so I want to explicitly retrieve what
they are and store them somewhere. The storing isn't the problem, I
would only like to know how I can query for these settings. It can
probably be done using WMI, but how?
