FIX: Incorrect Return Values from COleDateTime Members

    enum DateTimeStatus
    {
        valid = 0,
        invalid = 1,    // Invalid date (out of range, etc.)
        null = 2,       // Literally has no value
    };
				

MORE INFORMATION

Because of the problem outlined previously in this article, code that checks the return value from these functions may believe that a failure has occurred when in fact the Date/Time was set correctly. For example, the following code will ASSERT even though the call was successful:

   COleDateTime myodt;
   VERIFY(myodt.SetDateTime(96,1,1,10,45,0));
				

To work around this problem, test the success of the call by calling the COleDateTime::GetStatus() member. Compare the value returned by GetStatus() against 'valid' to check for success as shown in this example:

    COleDateTime myodt;
    myodt.SetDateTime(95,6,1,23,45,0);
    VERIFY(myodt.GetStatus() == COleDateTime.valid);
