    I'm not terribly familiar with protection. Here's an example of what i want to do:

        Class Outer
        Friend Class Inner
            Private A As Integer
            Private B As Integer
            Private C As Long

            Sub Set_Values(Some_Object As whatever)
                A = Some_Object.A
                B = Some_Object.B
                C = Some_Object.C
            End Sub

            Friend Function Get_A() As Integer
                Return A
            End Function
                Friend Function Get_B() As Integer
                Return B
            End Function
                Friend Function Get_C() As Long
                Return C
            End Function
        End Class
    End Class

    The idea is to make the variables writeable from Outer, but readable from outside Outer. I did not want to use Property, because all three variables are set from the same object. They are set multiple times. I could probably make Inner itself private, and move the Gets to Outer, but i was wondering if it could be done all in one class. It would also help me understand Access Levels a little better.

    In addition to Zhao, 

    You're not the first one thinking about Access Modifiers in another way that it is meant. Access modifiers are meant to make better programming possible. 

    It is not about the access of data or something like that, but to make parts of programs invisible for other programmers.

    Also try to use the right members of a .Net program. They can have in other program languages different names but they exist from 

    1. Constructors
    2. Methods (Functions and Sub in VB)
    3. Properties

    The use of properties seems unnecessary but as soon as you start using documentation and by that making your program easier to use for programming, you will recognize the benefits of those.

    Hi Brian Tkatch,

    Thank you for posting here.

    I'm not sure why you use inner class. You can consider using the following code to do it.

    Here's the code of my test:

    Module Module1
    Sub Main()
        Dim stu As student = New student() With {
        .A = 21,
        .B = 112,
        .C = 200L
        }
        Dim outer As Outer = New Outer(stu)
        Console.WriteLine($" A: {outer.Get_A()} B: {outer.Get_B()} C: {outer.Get_C()} ")
        Console.ReadLine()
    End Sub
End Module

Class Outer
    Private A As Integer
    Private B As Integer
    Private C As Long

    Public Sub New(ByVal Some_Object As student)
        A = Some_Object.A
        B = Some_Object.B
        C = Some_Object.C
    End Sub
    Public Function Get_A() As Integer
        Return A
    End Function
    Public Function Get_B() As Integer
        Return B
    End Function
    Public Function Get_C() As Long
        Return C
    End Function
End Class

Class student
    Public Property A As Integer
    Public Property B As Integer
    Public Property C As Long
End Class

    Result:

    Hope it could be helpful.

    Best Regards,

    It's just what i was trying at the time. So, i started playing with protection levels, because i do not understand them well. Then i figured i'd ask if it was possible.

    They are really access levels.  Take a look at this.

    Reading them and deeply understanding them, i find, are two completely different things. :)

    Hi Brian Tkatch,

    The following references may help you understand access modifiers in VB.NET.

    1. Understanding Access Modifiers In VB.NET
    2. Visual Basic (VB) Access Modifiers (Public, Private, Protected, Friend)

    Hope them could be helpful.

    Thank you. I am looking to learn through my own examples rather than study, as they are not really important to me right now, so i am not that interested. When a situation comes up like the one above, i get the interest to learn it, and that is why i asked for that specific example. The one thing i have learnt in this thread is that specific case above cannot be done. :)

    I may come back to those links next time such a situation arises. Thank you for listing them.

    Good points.

    I always wonder when to use Properties. In most cases, i do not need to hide the variables, so i just friend the variables and move on. I tried them in the case above so i could have separate modifiers for the Get and Set, but, there is no access modifier to do what i want, in the way that i wanted. Maybe next time. :)

    Hi Brian Tkatch,

    Hope following references can help you understand when to use nested classes. 

    1. When and why to use Nested Classes?
    2. Private nested classes

    Code in the first reference is C#, and you can convert them to VB.NET.
