Hi, all:

My VC6 MFC application is recognized as a Unicode application by the driver
manager, so when I read nchar fileds in MS SQL Server database, the
SQL_WCHAR does not convert to SQL_CHAR, and the application ASSERT failure
at CRecordset::GetDefaultFieldType function.
But I don't have "_UNICODE" defined, and have no "W" suffix functions
called, and my old version program compiled on Feb 2004 just work fine.
(source code lost unfortunatally)

I read docs like:
http://msdn.microsoft.com/library/de...er_manager.asp
http://msdn.microsoft.com/library/de...de_drivers.asp
but can't find the right answer.

Could any one tell me how dow the driver manager judge the application to be
Unicode aware?

Best Regards,
Qiang He
