In week view the title has year if different from the current... except when dates cross 2 months, in this case the year is not present.

As near as I can tell something in the "StripFormat" method is clobbering the format string. This method builds the format strings: CString CXTPCalendarCaptionBarTheme::CDateLabelPart::_FormatDate(COleDateTime dtDay1, COleDateTime dtDay2, BOOL bShowMonthDay) You'll see strFormat2 is made from strFormat1 here: CString strFormat2(strFormat1); << these should be 2 distinct CStrings now. Instead as you'll see code acts like it's one  Removing 'y' from strFormat1 ALSO removes it from strFormat2, clobbering it. This is a minor display bug, but it also indicates something seriously wrong going on. Maybe it's some simple thing but I don't know why it's happening. If you want to fix it temporarily while CJ engineers go mad, stick the 'y' back on strFormat2. approximately line 1676 in XTPCalendarCaptionBarControl.cpp strFormat1 = CXTPCalendarUtils::RemoveFormatPart(strFormat1, _T('y')); strFormat2.Append(_T("yyyy")); // WHAT!?? |

Try to use pDayView->SetDayHeaderFormat(_T("%a, %b %d")); or any c-style day format - it give you full control on Day Header titles without stripping something in old code in DayView and in multi-column week / work week modes.
You can also try new mode GetCalendarCtrl().m_bFullDateMode = TRUE;
a small comment to prev post:
CString strFormat2(strFormat1); //this is 2 distinct CStrings now - Surprise you don't understand it.
Removing 'y' from strFormat1 NOT removed it from strFormat2.
Try to Debug this piece of code if you not trust CString constructor. ------------- Mark Doubson, Ph.D. |

Try to Debug this piece of code if you not trust CString constructor. << With all due respect mdoubson, that was my point. They are 2 distinct strings yet the code is "acting" as if they are one. I watched it in the debugger and when strFormat1 was stripped, it also stripped strFormat2. The CString constructor worked fine. I haven't had a chance to play with it further since I do have other tasks but it acts like a memory overwrite. The proof was in the display and in the debugger. Has anyone at CJ tried or been able to duplicate the bug? Maybe it's a peculiarity of a certain build environment or properties.  |

This effect can also be seen in the demo so its nothing unique with my code. Compiled with VS 2005. Static Unicode. After:

Your watches show differences - one don't have comma !?

Correct. When the yyyy is stripped from strFormat1 it also strips it from strFormat2 and leaves the comma in strFormat2. The display in the caption bar shows this as well. It shows something like: July 3 - July 10, |

If the error is never produced while scrolling, then it must be either the compiler or the build. I see nothing obvious in the code that is producing the error or I would have fixed it a long time ago. When the strip method returns strFormat1, strFormat2 is also changed. VS 2005 using static, unicode definitely fails. Perhaps someone can configure a 2005 build and see what they get. As you can see, it can be reproduced using week or month modes.   |

This is current (after official 13.1 release) MFC Calendar source updates: https://forum.codejock.com/uploads/DemoVersion/CalendarControlMFCUpdated.rar - https://forum.codejock.com/uploads/DemoVersion/CalendarControlMFCUpdated.rar ------------- Mark Doubson, Ph.D. |

The results seem to be improved but problem still occurs when transitioning between 2 different months such as Apr-May etc. Tested with Visual Studio 2005 Visual Studio 2008 Static Unicode debug Static Unicode release CJ Version 13.1 with the update from this thread (after official 13.1 release) . Used "Deployment Wizard" to compile libraries so any optimizations are provided by CJ. Build command lines are unmodified from CJ. |

I don't understand the term improved here - is it working or not?
Could you run static app https://forum.codejock.com/uploads/DemoVersion/CalendarDemoStatic.rar - https://forum.codejock.com/uploads/DemoVersion/CalendarDemoStatic.rar and see some problems?
Of cource - this is non-uncode release mode. If you want - I can build static unicode release also. ------------- Mark Doubson, Ph.D. |

The example you provided fails in exactly the same manner. 1. Week view display (column or standard). Display is: "February 23 - March 01," Note the comma trailing 05. 2. Month view display. Display is: "February - March," Again note the trailing comma. This is consistent with the debugger output and program display in my testing. It would seem that Unicode is not the determining factor. |

The snaphot you use - 13.0. This is 13.1 run from my link (check-box for MultiColumn mode - on your snapshot - radio-button).

Right - so the problem is in some local settings - for XP-RU everything is proper. I will switch to XP-EN and give you know ------------- Mark Doubson, Ph.D. |

The problem was not in code you pointed but on more deep level in old code of CXTPCalendarUtils::StripFormat function ------------- Mark Doubson, Ph.D. |

It now works properly in my builds. Thank you for the fix.
