//	Purpose :	Wrapper function for Gettting resource with Specified
//				language ID.	
//				In WinNT, GetThreadLocale() SetThreadLocale() works
//				and before getting resource, change LangId temporary,
//				call normal API for getting resource,
//				and reset LangID to previous one.
//				In Win95, SetThreadLocale() does NOT work.
//				in this case, Load resource directory and
//				find spcified language resource.
