   Console::WriteLine( "MinSupportedDateTime: {0:D2}/{1:D2}/{2:D4}", myCal->GetMonth( myMin ), myCal->GetDayOfMonth( myMin ), myCal->GetYear( myMin ) );
   
   // Display the MaxSupportedDateTime.
   DateTime myMax = myCal->MaxSupportedDateTime;
   Console::WriteLine( "MaxSupportedDateTime: {0:D2}/{1:D2}/{2:D4}", myCal->GetMonth( myMax ), myCal->GetDayOfMonth( myMax ), myCal->GetYear( myMax ) );
}
