SUMMARY

The behavior of the Active Template Library (ATL) COleDateTime::SetDate method is different in Microsoft Visual C++ .NET 2003 from the behavior of this method in Microsoft Visual C 6.0. When a user enters a date that is not valid, the COleDateTime::SetDate method no longer sets the status of the COleDateTime object to invalid.
