Sub Classes?

[Dmyze]

I don't know how to do this, but this is what I want to do in code:

Dim oWeek as new FiscalWeek(iWeekNumber, iYearNumber)

iWeek = oWeek.CurrentWeek.WeekNumber
iYear = oWeek.CurrentWeek.YearNumber
iNextWeek = oWeek.NextWeek.WeekNumber
iLastWeek = oWeek.NextWeek.YearNumber

I can "kinda" do it by making a class inside a class:

Public Class FiscalWeek


  Private Shared iNextWeek As Integer
  Private Shared iLastWeek As Integer
  Private Shared iCurrentWeek As Integer
  Private Shared iNextYear As Integer
  Private Shared iLastYear As Integer

  Public CurrentWeek As New cCurrentWeek()
  Public NextWeek As New cNextWeek()

  Class cCurrentWeek

    Public ReadOnly Property WeekNumber() As Integer

      Get
        Return iCurrentWeek
      End Get

    End Property

    Public ReadOnly Property YearNumber()

      Get
        Return iCurrentYear
      End Get

    End Property

  End Class

  Public Class cNextWeek

    Public ReadOnly Property WeekNumber() As Integer

      Get
        Return iNextWeek
      End Get

    End Property

    Public ReadOnly Property YearNumber()

      Get
        Return iNextYear
      End Get

    End Property

This was working pretty much, but I've found when I created two seperate instances of oWeek the Current week gets changed in both when I change it in one. it dosn't make sense to me, but I must be doing this wrong, what is the propper way to have a "nested property"?

Shared will share the same data for all instances which is not what you want. Try something along this line:

Public Class FiscalWeek
 
    Private _CurrentWeek As New SubWeek()
    Private _NextWeek As New SubWeek()
 
    Public Property CurrentWeek() As SubWeek
        Get
            Return _CurrentWeek
        End Get
        Set(ByVal Value As SubWeek)
            _CurrentWeek = Value
        End Set
    End Property
 
    Public Property NextWeek() As SubWeek
        Get
            Return _NextWeek
        End Get
        Set(ByVal Value As SubWeek)
            _NextWeek = Value
        End Set
    End Property
 
End Class
 
Public Class SubWeek
 
    Private _WeekNumber As Integer
    Private _YearNumber As Integer
 
    Public ReadOnly Property WeekNumber() As Integer
        Get
            Return _WeekNumber
        End Get
    End Property
 
    Public ReadOnly Property YearNumber()
        Get
            Return _YearNumber
        End Get
    End Property
 
    Public Sub New()
 
    End Sub
 
    Public Sub New(ByVal wkNum As Integer, ByVal yrNum As Integer)
        _WeekNumber = wkNum
        _YearNumber = yrNum
    End Sub
 
End Class

if i understand what you are trying to do try this code for the class

Public Class returnDates

    Dim currentWeek As Integer
    Dim currentYear As Integer

    Public Sub New(ByVal tempWeek As Integer, ByVal tempYear As Integer)
        currentWeek = tempWeek
        currentYear = tempYear
    End Sub

    Public Function returnCurrentWeek() As Integer
        Return currentWeek
    End Function

    Public Function returnCurrentYear() As Integer
        Return currentYear
    End Function

    Public Function returnNextWeek() As Integer
        Return currentWeek + 1
    End Function

    Public Function returnNextYear() As Integer
        Return currentYear + 1
    End Function
End Class

and then use this code to create class and call functions

Dim a As New returnDates(1, 2003)
        Dim b As New returnDates(10, 2010)

        Dim temp As Integer

        temp = a.returnCurrentWeek
        temp = a.returnCurrentYear
        temp = a.returnNextWeek
        temp = a.returnNextYear

        temp = b.returnCurrentWeek
        temp = b.returnCurrentYear
        temp = b.returnNextWeek
        temp = b.returnNextYear

hope i got it and this helps!

That is where I started, but I have so many properties that I want to add to the weeks like, start date, end date, weeknumber, year number, that it seems to me that it would make sense to have it grouped together.

ie:

oWeek.CurrentWeek.YearNumber
oWeek.CurrentWeek.WeekNumber
oWeek.CurrentWeek.StartDate
oWeek.CurrentWeek.EndDate

and then that repeted for LastWeek, NextWeek, and LastYear.

I did figure out how to get it thead safe, it does everything i want it to do except when you referance it oWeek. you get the oWeek.cCurrentWeek and I'd like that to be invisible. If I make the sub class private, it won't let me use the "Public CurrentWeek As cCurrentWeek"

Public Class FiscalWeek

  Public CurrentWeek As cCurrentWeek
  Public NextWeek As cNextWeek
  Public LastWeek As cLastWeek
  Public LastYear As cLastYear

  Public Sub New(ByVal WeekNumber As Integer, ByVal YearNumber As Integer, ByVal sSQLSP As String)

    ...

    CurrentWeek = New cCurrentWeek(WeekNumber, YearNumber, cn)
    ...

  End Sub 



 Class cCurrentWeek

    Private m_Week As Integer
    Private m_Year As Integer
    Private m_Start As Date
    Private m_End As Date

    Sub New(ByVal iWeek As Integer, ByVal iYear As Integer, ByVal cn As SqlConnection)
      m_Week = iWeek
      m_Year = iYear
      FindDates(iWeek, iYear, cn)

    End Sub

    Private Sub FindDates(ByVal iWeek As Integer, ByVal iYear As Integer, ByVal cn As SqlConnection)
	..

    End Sub



    Public ReadOnly Property WeekNumber() As Integer

      Get
        Return m_Week
      End Get

    End Property

    Public ReadOnly Property YearNumber()

      Get
        Return m_Year
      End Get

    End Property

    Public ReadOnly Property StartDate() As Date

      Get
        Return m_Start
      End Get

    End Property

    Public ReadOnly Property EndDate() As Date

      Get
        Return m_End
      End Get

    End Property

  End Class
End Class
