The example prints out the range of dates selected by the user. To try the example, place a MonthView control on a form and paste the code into the Declarations section of the code module. Start the project and select various date ranges (set the MultiSelect property to True).
Private Sub MonthView1_SelChange(ByVal StartDate As Date, ByVal EndDate As Date, Cancel As Boolean)
Dim d As Date
d = StartDate
Debug.Print "Start"
While d <= EndDate
Debug.Print d
d = d + 1
Wend
Debug.Print "End"
End Sub
