I did a little research and found in a few places information that UNICODE is used by Windows headers, _UNICODE is used by C-runtime/MFC headers. However I did not find official explanation of this. Some examples, including a few MSDN ones, define both. E.g. see: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wss/wss/_exch2k_getting_the_host_domain_name.asp Can you tell now where we need to use which one?
