Hi, Experts

I have problem to auto set the date for example:-

Due Date = 31-May-2011, Then Date A is 1 day before the due date, Then Date B is 2 days before Date A, Then Date C is 14 days before Due Date. How can i get the date which is exclude Sunday.

Below code is the sample code provided by CodeCruiser that previously i use in my program and now i need more advance calculation :http://www.experts-exchange.com/Programming/Languages/.NET/.NET_Framework_1.x/Q_25357487.html

Dim sDate As Date = Date.Parse("30/03/2010")
                Dim dayCount As Integer = 10
                For i As Integer = 1 To dayCount
                    sDate = sDate.AddDays(-1)
                    If sDate.DayOfWeek = DayOfWeek.Sunday Then
                        sDate = sDate.AddDays(-1)
                    End If

Just put it into a function, with variable startDate and integer as days

        Dim dueDate As Date = Date.Parse("30/03/2010")
        Dim dateA As Date = ReturnDate(dueDate, 1)
        Dim dateB As Date = ReturnDate(dateA, 2)
        Dim dateC As Date = ReturnDate(dueDate, 14)
Private Function ReturnDate(ByVal startDate As Date, ByVal days As Integer) As Date
        Dim sDate As Date = Date.Parse(startDate)
        For i As Integer = 1 To days
            sDate = sDate.AddDays(-1)
            If sDate.DayOfWeek = DayOfWeek.Sunday Then
                sDate = sDate.AddDays(-1)
            End If
        Return sDate
    End Function
