BUG: Format("%D") Fails for COleDateTime and COleDateTimeSpan

• The Microsoft Foundation Classes (MFC), included with:
  • Microsoft Visual C++, 32-bit Editions, version 4.2

SYMPTOMS

COleDateTime::Format("%D") fails to return the day in the object.

COleDateTimeSpan::Format("%D") fails to return the total days.

RESOLUTION

Instead of using Format use COleDateTime::GetDay() or COleDateTimeSpan::GetDays() to get the day value and use CString::Format to put it into a CString. The sample code below illustrates this using CString::Format.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.

Sample Code

   COleDateTimeSpan span;
   // Set to 1 day 2 hours 3 minutes and 4 seconds
   span.SetDateTimeSpan(1,2,3,4);

   CString str;
   str = span.Format("%D;%H;%M;%S"); // BUG:Day(s) is not found in CString

   // Following is equivalent to the above
   str.Format("%02d;%s", span.GetDays(),
               (LPCTSTR)span.Format("%H;%M;%S"));

   COleDateTime time;
   time = COleDateTime::GetCurrentTime();
   str = time.Format("%D;%H;%M;%S"); // BUG:Day is not found in CString

   // Following is equivalent to the above
   str.Format("%02d;%s", time.GetDay(),
              (LPCTSTR)time.Format("%H;%M;%S"));
