Getting Excel settings

Hi everyone,
I am working with VC++ and I control Excel through the COM interface. I have to set the decimal point und the 1000 delimiter for an abroad customer according to his Excel settings in the function SetNumberFormat(...). How can I get his settings (by the means of "Office Button -> Excel Options -> Extended-> Use delimiter of operating system ...")?

Thanks
Vaclav
