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.

bOK = dtDate.SetDate(2003, 2, 29); if((bOK == 0) && (dtDate.GetStatus == COleDateTime::valid)) {   AfxMessageBox(&quot;Date Valid!&quot;); }  Run the application.

The dtDate variable returns a valid state for a date that is not valid.
