Private Or Protected Set For A MustOverride Property?
Jul 24, 2010
I'd like to have a Private or Protected "Setter" for a property that also happens to be an abstract (MustOverride). I'm porting some code from C# to VB and in C# this is pretty straight forward. In VB not so much (for me anyway).
Some code...
In C#...
public abstract class BaseClassWithAnAbstractProperty
{
public abstract int AnAbstractIntegerProperty { get; protected set; }
}
[Code]....
The issue seems to be the inability to flesh-out the Get/Set specifics in the declaration.

I searched on the forum / Internet for the solution how a PropetryInfo object (of a Public property) can reveal if it has a Private Protected Setter ... it was all in vain .... all help I found was about how to "Set" value of a public property having a Private Setter.I would like to know if I have a PropertyInfo object of a public property, how would I know if its Setter is Non Public?
I tried, in a exception handling block, where I did a GetValue of the PropertyInfo object and then called SetValue by setting the same value back... but to my surprise it worked well and didn error out.

I am having a Friend Class InterceptingChannelBase class.It has a property as below:
Protected ReadOnly Property InnerChannel() As TChannel
Get
Return Me.innerChannelT
[code]....
This class is being inherited by (Friend Class InterceptingInputChannel) class which in turn contains another (Private Class TryReceiveAsyncResult) class.The property above is being used in this private class as below:
Public Sub New(ByVal channel As InterceptingInputChannel(Of TInputChannel), ByVal timeout As TimeSpan, ByVal callback As AsyncCallback, ByVal state As Object)
MyBase.New(channel, callback, state)
[code]....
I am getting the error on the above underlined statement saying that Protected Readonly Property InnerChannel is not accessible in this context because it is declared asa Protected.As far as i think,if i declare a property in class as 'Protected' then if this class is inherited by 'another' class then i can use this property and it should not throw an error.

In ASP.NET using VB.NET, you can define the wired up button click event (to an ASP.NET server control) in 2 different ways (for the purpose of this conversation - manually wiring up via button property not in question here):
Double click on the button in the designer which produces an event in the code behind with a Protected method.In the code behind, select the button from the list of controls, and then select it's 'Click' event. This produces a Private method.I understand the difference between Private and Protected; why based on how the wired up event is autocreated it generates a different Access Level on the method?

What purpose do protected or private (non-static) events in .NET really serve?It seems like any private or protected event is more easily handled via a virtual method. I can (somewhat) see the need for this in static events, but not for normal events. Have you had a use case before that clearly demonstrates a need or advantage for a non-static protected or private event?

Is it possible to call a protected method via reflection. I am using this:
Me.GetType.InvokeMember(Stages(CurrentStage),
Reflection.BindingFlags.InvokeMethod,
Nothing,
Me,
Nothing)
Which always calls a method with no params or return. The idea is that the user of my object (transactional processing of business logic) inherits the base class adds in a load of private methods to fire. They then add these method names to a list in the order they would like them fired and the code above will take care of firing them.
It works fine with public methods but not with private or protected methods in the same class (Protected because I have some 'standard' pre built methods to add to the base class). Realistically I could make the methods public and be done with it but my inner nerd wont allow me to do so...
I am assuming this is a security feature. Is there a way to get around this or does anyone have any suggestions on how to proceed but keep my tasty, tasty visibility modifiers in tact?
(NOTE: ITS IN VB.NET but a C# Answer is fine if that is what you are comfortable with).

i have have a few questions about the syntax of the lan.:
1) What is the 'Get' statement and when do you use it?
2) Whats the difference between public, private, protected etc... when declaring functions and subs.
3) When would you use the overrides property?

I Like .NET automatic properties, in C# it so easy to declare readonly property by declaring its set section as private like this:
public String Name{ get; private set; }
But when I tried that in VB.NET I was shocked that it is not supported as mentioned here and I have to write it as follows:
Private _Name as String
Public ReadOnly Property Name as String
Get
[Code].....
What the difference between these declarations in VB.NET, which one is preferred and Why?
Which one will affect compile time, runtime or performance at all?

I am trying to use fluent nhibernate in a MVC project. It seems the entities should have properties that are virtual and the set should be private for IDs. I use vb language. So tried using overrideable. It gives an error...
Public Overridable Property DesignId() As Integer
Get
End Get
Private Set(ByVal value As Integer)
End Set
End Property
It says property cannot be overrideable because it has a private accessor.

is there a way to have the Get part of a property available as public, but keep the set as private?Otherwise I am thinking I need two properties or a property and a method, just figured this would be cleaner.

I am programmer from some time only, I have certain doubts in fundamentals, could you please clarify on the following:Case 1:

Does case 1 and case 2 yield same result, I mean is a private value necessarily in there?, can we use property itself to use its own value in its Set and get statements?

Dim box As MultiTextBox = New MultiTextBox
Dim i As Integer
for i = 1 to 3 Step 1
lengthWidthHeight = MultiTextBox.GetItemValues()
Next i
This excerpt of code is using the NXOpen API. In the NXOpen API, the MultiTextBox class is public. However, when I compile the code I get the message:
'NXOpen.UIStyler.MultiTextBox.Protected Sub New(ptr As System.IntPtr)' is not accessible >in this context because it is 'Protected'
My question is, how am I getting an error about protected scope? Could it also be that the API documentation is incorrect?

I was trying to access the following property using Reflection because I don't have the original source code (suppose this was decompiled through Reflector). It seems that something is special about it being "private virtual" or maybe because it has "_" in the beginning of the property. I can access all the other private properties no problem except this one. Just can't figure out what I am doing wrong:
private virtual String _MyProperty
{

VB.NET 2008 .NET 3.5 I have two base classes that are MustInherit (partial). Let's call one class OrderBase and the other OrderItemBase. specific type of order and order item would inherit from these classes. Let's call these WebOrder (inherits from OrderBase) and WebOrderItem (inherits from OrderItemBase).
Now, in the grand scheme of things WebOrder is a composite class containing a WebOrderItem, like so:

I'm having some very weird issues with interfaces right now.
I have a very simple setup. In one of my class, I have a Property implementing a Property from an Interface.
In my class it's like:
