It seems that there is a significant performance loss, when handling many events, say 1000 and up.
Vertical calendar scrolling gets extremly slow and inresponsive, especially on my older PCs and in Debug version.
Test case:
In CalendarDemo I added the following code in CCalendarDemoDoc::AddTestEvents().
It adds 15 events per day, starting at 6:00am, repeated for last 3000 days.
// add test events
COleDateTime dtNow(COleDateTime::GetCurrentTime() + spTimeShift);
COleDateTimeSpan spDay(1, 0, 0, 0);
COleDateTimeSpan sp15min(0, 0, 15, 0);
COleDateTimeSpan spHour(0, 1, 0, 0);
// NEW -------------- add a few thousand events
COleDateTime dtInit;
dtInit.SetDateTime(COleDateTime::GetCurrentTime().GetYear(), COleDateTime::GetCurrentTime().GetMonth(), COleDateTime::GetCurrentTime().GetDay(), 6, 0, 0);
for (int d = 0; d < 3000; d++) {
COleDateTimeSpan spD(-d, 0, 0, 0);
for (int h = 0; h < 15; h++) {
COleDateTimeSpan spH(0, h, 0, 0);
CXTPCalendarEventPtr ptrEvent = NewEvent(pCalendarData, dtInit + spD + spH, dtInit + spD + spH + spHour, _T("Test event"), _T("New Location"), nScheduleID);
ptrEvent->SetBusyStatus(xtpCalendarBusyStatusTentative);
if (!pCalendarData->AddEvent(ptrEvent)) {
ASSERT(FALSE);
return;
}
}
}
// END -------------------------------
Set the time scale from 2:00 to 23:00 and switch to Work Week view.
Mark, can you please check if you get this performance loss, too and what's its cause?
Thanx, Marco

I repeat your case - it was very long LOAD time but I don't see performance problem with vertical bar scrolling and with respond
