This article was previously published under Q153292
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.
