SYMPTOMS

When calling the COleDateTime::Format member function with VAR_DATEVALUEONLY or VAR_TIMEVALUEONLY, you will get the following compiler error: 
   error C2668: 'Format' : ambiguous call to overload function (new
                           behaviour; please see help)

CAUSE

The problem is caused by not defining VAR_DATEVALUEONLY and VAR_TIMEVALUEONLY as DWORD in Oleauto.h.

RESOLUTION

The workaround is to type cast these constants to DWORD.
