I think this has been around for some time, but thought I'd point it out.

Find in CalendarDemoView.

                INT_PTR CXTPCalendarControl_Custom::OnToolHitTest(CPoint point, TOOLINFO* pTI) const

This will cause a crash in unicode:

                int nBuffSize = strToolText.GetLength()*2 +10;
               TCHAR* pBuffer = (TCHAR*)malloc(nBuffSize);
                STRCPY_S(pBuffer, nBuffSize, (LPCTSTR)strToolText);
                pTI->lpszText = pBuffer;

I did a quick fix as follows:

                int nBuffSize = strToolText.GetLength() +10;
                TCHAR* pBuffer = (TCHAR*)calloc(nBuffSize,sizeof (TCHAR));
                STRCPY_S(pBuffer, nBuffSize, (LPCTSTR)strToolText);
                pTI->lpszText = pBuffer;

I found custom tooltips much easier to implement by editing the source rather than using a custom control anyhow.

Sure - this is very juniour task. But in 13.1 this is public member of CXTPCalendarControl

CString m_sCustomFormat4Tooltip;

//Free-styled tooltip tag-based way to fill tooltip string

//used tags <BODY>,<LOC>,<SUBJ>,<TIME> in any combination and order and with any fillers
