ID: Q153292

The information in this article applies to:

The Microsoft Foundation Classes (MFC), included with:
- Microsoft Visual C++, 32-bit Editions, versions 4.0, 4.1

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.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This problem was corrected in Visual C++ version 4.2.
