Unicode version of ACEDAO.dll

Tech-Archive recommends: Fix windows errors by optimizing your registry

I'm trying to port my c++ code from 6.0 to 2008. My C++ application accesses
97 Access database (.mdb) file. I would like to update the my database to
Access 2007 and use C++ code to access the .mdb and .accdb files. I followed
this article

http://msdn.microsoft.com/en-us/library/cc811599.aspx

This step
#import <C:\\Program Files\\Common Files\\Microsoft
Shared\\OFFICE12\\ACEDAO.dll> rename( "EOF", "AdoNSEOF" )

will generate acedao.tlh file. The code works on the non-unicode
application. However, my application is unicode enabled, when I compiled the
with acedao.tlh, it will cause a lot of errors. Is there a ACEDAO.dll
unicode version? If not, is there I can do to make my application uses the
acedao.tlh?

Thanks.
