	As a direction to eliminate this problem (and related problem you don't report but can confirm [if you have horizontal scroll bar in multi-scheduled day view - try to use right arrow step from most left column to next - as a result you will come to ANOTHER day instead of another schedule of the same day] - I disable horizontal scroll bar in DayView mode - and all problems disapear: BOOL CXTPCalendarDayView::GetScrollBarInfoH(SCROLLINFO* pSI, int* pnScrollStep) { return FALSE; /////////////////////// Is it good for you - if user don't like too small columns - he can resize app window?

	Hi , Actually we don't want to disable horizontal scrall bar, as we have multiple schedules columns. Our customers need to use smalls views in which they will need horizontal scroll bar. So disabling the scroll bar is NOT and option for us. Please let us know any other solution / fix to this problem

	I fixed it - this is updated function code: BOOL CXTPCalendarDayView::GetScrollBarInfoH(SCROLLINFO* pSI, int* pnScrollStep) { UNREFERENCED_PARAMETER(pnScrollStep); ASSERT(pSI); if (!pSI) return FALSE; int nMinColumnWidth = RecalcMinColumnWidth(); if (nMinColumnWidth <= 0) return FALSE; int nColumnsCount = GetTotalGroupsCount(); CRect rcClient = _GetScrollRectClient(); int nFullWidth = nColumnsCount * nMinColumnWidth; if (nFullWidth <= rcClient.Width()) return FALSE; pSI->nPos = min(m_nScrollOffsetX, nFullWidth); pSI->nMin = 0; pSI->nMax = nFullWidth-1; pSI->nPage = rcClient.Width(); return TRUE; }

	Hi Mark, Crash has been resolved by above code but following are the open issue- 1) Resizing the event change the date Eg. 19th Jan. to 20th Jan. this is wrong bihaviour. 2) Inline editing display problem due to change date. Scr shot for more details

	Hi, I am afraid that we still running very different source set - even I gave you a few patches. I can't reproduce your bug in Office2007 theme and in old themes like Office2003. Event resizing works only in vertical (up and down) directions and so day not changed. Wait for release or get some prerelease (beta 13?) if it is possible(?)

	I don't think so - you should use official way. I can't attach source of component as forum's topic attachment(!?)
