Another possible easy solution would be to add some amount of time to rangeEnd (1 minute for example). In this case Doubles should be compared fine...

Hi,

I think I see the problem. It might happen because Dates are represented in OLE by Double values. And 2 equal Dates could be represented by not exactly same Doubles. The defference is small, but we have to keep in mind this when compare Dates. This is not implemented in ShowDays and as a result sometimes it removes all days and do not adds one.
 
To avoid that use ShowDay method to show only one day.

Using 9.81 ActiveX

I keep getting the following error when the user press the forward or back button below is the error and below that is the code which produces the error. This problem does not show on my computer but only on some computers.

Exception:
 
System.Exception: TargetInvocationException in Navigate_Cal_Back_And_Forward()., CalendarControl.ViewType = xtpCalendarDayView, CalendarControl.ActiveView.DaysCount = 1, date range = 2006-11-02 00:00:00.000 to 2006-11-02 00:00:00.000
