Friend Modifier Not Working?

View 5 RepliesWhy Modifier Set To Friend In WinForms
Sep 14, 2010When adding a new control to the designer in Winforms, the modifier on the control is set to Friend, but the default modifier is Private (right clicking the property and resetting the modifier). Is there a setting to set the modifier to default (Private)?
View 2 RepliesWhere Is The Friend Access Modifier Intended To Be Used
Mar 21, 2012The only place I've seen the Friend modifier used is in the WinForms designer, as alluded to in Why is the modifier set to Friend in Winforms? and VB.NET: what does the 'friend' modifier do?. The Friend modifier appears to be an almost arbitrarily wide access level that was created to solve some historic architectural problem in VB, I just wonder if anyone has a meaningful continued use for it?
I have had some desires to expose methods only to a given namespace so as to roll the functionalities of a related collection of objects together and manage any of their non-thread-safe methods, while exposing the safe public methods to a wider scope in the same assembly. This access level does not exist yet Friend does. Possibly a corollary question then, is my usage of assemblies and namespaces at odds with what is intended?

Change The Default Modifier From Friend To Private In The Windows Forms Designer In VS 2008?
Jul 2, 2010When I develop a Windows Forms app in Visual Studio using C#, every control that I add to my form is by default marked as private, which is what I want.
When using VB.NET, every control is by default marked as Friend (the equivalent of internal in C#), which is not what I want.
Can I just change this default? It seems like surely it's a setting somewhere.

View 1 Replies.net - "Public Friend" Versus "Friend Friend"?
Apr 21, 2011I've been reading about access modifiers in VB.Net lately, and there is something that I can't really understand: How do elements in a Class (or Module) inherit the modifiers of their enclosing block?For example, suppose you have a Friend class Bla in an assembly, with a public method Foo:
Friend Class Bla
Public Sub Foo
(...)
End Class
Does it behave differently than when Foo is set to Friend?
Friend Class Bla
Friend Sub Foo
(...)
End Class
Pass A Delegate Into A Constructor Of An Abstract Class From A Descendant's Constructor?
Feb 15, 2010I have an abstract class which requires a delegate to function. I pass the delegate into the constructor. Now that I have a non default constructor I need to call the abstract class's constructors from the concrete class which means that I need to use MyBase.New(...). I have included a quick example below.
Public MustInherit Class BaseClass
Public Delegate Sub WorkMethod()
Private _Work As WorkMethod
[code]....
I have tried to do this but I keep getting the following error: "Implicit reference to object under construction is not valid when calling another constructor".Can I not do what I am trying to do above? I initially had the delegate setup in its own setter method. But then I am creating a deceptive API because it does require a point to a method to work properly.
Why Is Constructor Call Valid Only As The First Statement In An Instance Constructor
Nov 2, 2009what's the rationale behind this limitation: Constructor call is valid only as the first statement in an instance constructor i want to pass an argument to my constructor which validates this argument and calls mybase.new according to this argument but it doesn't let me

Public Class prob
Inherits System.ApplicationException
Public Sub New(ByVal problem As String, ByRef inner_exception As Exception)

Class Modifier For Method Calculate()
Oct 15, 2009I would like a answer to the following question: For instance:

View 2 Replies.net - Friend WithEvents In VB Vs Private In C#

For WithEvents is more or less clear(for using Handles, apparently). But why Friend in VB and private in C#...

View 4 RepliesSimulate C++ Friend In C# And Program?
Dec 20, 2010I can think of the following tricks:
Read only wrapper - like ReadOnlyCollection. The friend keeps the pointer to the modifiable object, while everyone else can access only the wrapper.Write delegate - the friend gives the constructor of the object a reference to a delegate as one of the parameters, the constructor fills it with an address to a private method that can be used to modify the object.Reflection - obviously a bad idea. Included for completeness.Multiple assemblies - put your friends together in a separate assembly and set your modifier methods internal.Expose the modifiable object, but add comments to modifier methods "This is an infrastructure method - don't call it!"Nested classes.[code]...

View 11 RepliesXML Serialize Friend Classes
Sep 23, 2009I have a few classes (about 15 or so) in VB.net (2005) that I would like to be able to serialize to xml. Unfortunately they are labeled as friend classes and cannot be exposed outside of the assembly.The assembly is a dll that is a com interop plugin to a CAD system. I have set all of my classes as friends so that they are not exposed outside of the assembly for 3rd party use. I am wondering if I even need to do that. Setting the class to public would allow me to serialize things. However I don't want people linking to the assembly and using the classes.Should I even worry about other programs linking to my assembly? In fact I don't think there is a large chance of this happening. I just don't like the idea of having almost all of my classes with a public scope.Is there a way to make a friend class serializable?

.NET Visual Inheritance: Friend Versus Protected?
Jun 18, 2010Why is it that some components/controls will not be inherited visually in a child form if they are declared with the access modifier Friend vs when they are declared with Protected. For example, I've got a DataSet object in my Parent Form that was initially "Friend" (I drag and dropped it to the form, so it was shown as a control in the designer view), but I noticed that my Child Form did not inherit the control as expected. Once I changed it to "Protected", it showed up in my Child form as expected.I am aware that Protected allows the Child Form to modify the inherited control, but how exactly does this tie in to the issue I described above?
