Imports Infragistics.Win
Imports Infragistics.Win.UltraWinSchedule

    Private Sub DisableFirstAndLastDayOfYear()

        '	Get a DayOfYear object for the first day of the year
        '	Note that the DaysOfYear collection is one-based so as
        '	to be more intuitive to use
        Dim dayOfYear As Infragistics.Win.UltraWinSchedule.DayOfYear
        dayOfYear = Me.ultraCalendarInfo1.DaysOfYear(1)

        '	Assert that we got the one we expected
        Debug.Assert(dayOfYear.DayNumber = 1, "Wrong DayOfYear returned in 'DisableFirstAndLastDayOfYear'!")
