SBYTE redefinition in vs2005

[abchjb]

today, I upgrade my application from vs2003 to vs 2005, but I meet a problem:
the type SBYTE define in dctypes.h also define in the vs2005's oledb.h.
in dctypes.h:
typedef Sint8 SBYTE;
in oledb.h:
typedef signed char SBYTE;

so error:
error C2371: 'SBYTE' : redefinition; different basic types
d:\microsoft visual studio 8\vc\platformsdk\include\oledb.h(798) : see declaration of 'SBYTE'

As far as I can see, the definition of BYTE and SBYTE in dctypes.h is not used any longer anywhere in the toolkit. So, you should try to remove the two lines from the header file and re-compile.

I also find this error in VS 2008,but I have not solved this problem.I have tried to remove the definition of the SBYTE,but i have not succeed.It will make more error.
