Q167338: BUG: Format("%D") Fails for COleDateTime and COleDateTimeSpan

Article: Q167338
Product(s): Microsoft C Compiler
Version(s): 4.2
Operating System(s): 
Keyword(s): kbcode kbVC500bug
Last Modified: 04-AUG-2001

-------------------------------------------------------------------------------
The information in this article applies to:

- The Microsoft Foundation Classes (MFC), included with:
   - Microsoft Visual C++, 32-bit Enterprise Edition, version 4.2 
   - Microsoft Visual C++, 32-bit Professional Edition, 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"));
