I am using a PropertyGrid control to edit my class properties and I am trying to set certain properties read-only depending on other property settings.This is the code of my class:
Imports System.ComponentModel
Imports System.Reflection
Public Class PropertyClass[code].....
This is the code I am using to edit the values:
Dim c As New PropertyClass
PropertyGrid1.SelectedObject = c
The problem is that when I set SomeProperty to True, nothing happens and when I then set it to False again it sets all properties Read-Only.

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.
i get the following error in the follwoing code , the word right is underlined in blue and the error is "1'Public ReadOnly Property Right() As Integer' has no parameters and its return type cannot be indexed."

Is there a way for implementers of an interface where a ReadOnly property is defined to make it a complete Read/Write Property ?
Imagine I define an interface to provide a ReadOnly Property (i.e., just a getter for a given value) :
Interface SomeInterface
'the interface only say that implementers must provide a value for reading
ReadOnly Property PublicProperty As String
End Interface
This means implementers must commit to providing a value. But I would like a given implementer to also allow setting that value. In my head, this would mean providing the Property's setter as part of the implementation, doing something like this :
Public Property PublicProperty As String Implements SomeInterface.PublicProperty
Get
Return _myProperty

Conceptually it seems like a derived class should be able to override a readonly property with a read write property. Why isn't this possible?
[code]...
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 have a user control and I'd like to give it a custom property named ReadOnly. I get "Keyword is not valid as an identifier", as it thinks I'm writing a ReadOnly Property named something.
so really I can call mine 'Read_Only', but I'm just curious if there's an easy way to get the other name in there, since then my control will be similar to the visual controls that have ReadOnly in the designer.
is it possible (and how) to make a readonly automatic property in VB 2010?
Public Class Foo
Public Property Value As Integer
Public Sub New()
[code]....
problem is that users can write to the property.
It seems that VB.NET and C# readonly keyword have some differences... Say, a ReadOnly property in C# can be assigned in some conditions, but in VB.NET - never?

I am using a Micrsoft Web Browser Control (i.e. the AxWebBrowser NOT the standard web browser). The only way I can declare the variable for it is as follows:
Dim wb1 As New AxSHDocVw.AxWebBrowser However I cannot then do the following: wb1.Name "WebBr1" It says the Property Name is ReadOnly
It seems that in the following example, TestProperty() and TestDouble() are functionally equivalent. Is the case? I usually use Property/Get when I have a single line "Return Variable_" type of "function", and Function when I have a more involved thing going on. Is that reasonable?

I am trying to develop a simple interface for allowing quick lists to be generated from classes. Basically, the interface needs to return an ID and a Name. However, some classes have a calculated name property which is read only, others just use a read/write name property. Basically, all I care is that it has a getter, it does not matter if the property has a setter. How can I write this interface to handle either or without throwing compile errors?

In my class there's an object belonging to Process class. So, in my wrapper class, I need to get the "StartTime" & "EndTime" of the process object. I'm having confusion whether to use a ReadOnly property for this or a function returning the date, in my wrapper class
Is it a good practice to use a function for this purpose or a property ?
