SYMPTOMS
When you include SHLOBJ.H in an MFC application, the following compiler
error occurs:
error C2371: 'BSTR' : redefinition
CAUSE
The SDK header file OAIDL.H and the MFC library both define a type BSTR.
RESOLUTION
To work around this problem, add the following definition before including
any MFC headers. In an AppWizard-generated application this can be done at
the beginning of the STDAFX.H include file:
#define _AFX_NO_BSTR_SUPPORT
