--- Comment #3 from Nikolay Sivov bunglehead@gmail.com 2009-10-14 09:31:14 --- I think I've accidentally found a way to support this. After some msdn browsing:
http://msdn.microsoft.com/en-us/library/dd373825%28VS.85%29.aspx
Apparently Win7 introduces a way to retrieve this data using GetLocaleInfo (or calendar api only, didn't tested yet) with a special flag:
LOCALE_RETURN_GENITIVE_NAMES
If it works it's the best way to use, cause it's transparent as much as possible.
I'll post new info here when get tests ready.
