Can't Make Difference Between Public Class And Private Class And Friend And Protected Friend Class

May 15, 2009

I can't make difference between public class and private class and friend and protected friend class.


[2005] Working Of Friend Class With Public Methods?

Feb 27, 2009

I understand how the class modifiers work like public, private, protected, friend and protect friend. They are pretty straight forward. However my question is, if I have a class is marked as friend, what should the properties and methods be marked as? Friend or public? Does it matter? I just want my classes at the lowest exposure level that will let my program work properly and that is friend. If I understand correctly, the public properties of a friend class are available to all members of the assembly. Wouldn't that be the same access level if the properties were all friend properties?The reason that I ask is that using the autocomplete feature to make new properties (type property and hit tab) it creates the new properties with the public attribute.

.net - "Public Friend" Versus "Friend Friend"?

Apr 21, 2011

I'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

Class Private/Public Naming Conventions?

Mar 25, 2011

I'm relatively new to .NET and am wondering how people handle naming their private variables and the public properties that access them. Like if you want to be able to just read it, but not write to it.


So far I've taken to putting a 'l' (for local) in front of the all the private variables so as to be able to use the full name for the property. Is there a better way around this, or do you just always have to have different names for private variable/public properties? If so, what sort of conventions do people use?

Its not a huge deal, its just a minor annoyance and I was wondering if I was missing something.

VS 2008 - Comparing Variables In Private Sub With Public Class

Nov 11, 2009

I have these list of RS-232 strings declared in my public class
Public Class TouchInterface
Dim WatchTVbtnCmd As String = "rs232command1"
Dim VolUpbtnCmd As String = "rs232command2"
Dim VolDownbtnCmd As String = "rs232command3"
Dim SystemOffbtnCmd As String = "rs232command4"
Dim RadiobtnCmd As String = "rs232command5"
Dim MusicbtnCmd As String = "rs232command6"

I then have this private sub. For the sake of this thread, what I would like to do is get the name of the label that was clicked which in the code below is already done, convert it to string (not sure if this needs to be done), this is also done in the code below. Next I want to compare the labelnamestring to all the variables in the public class to find out which one it is equal to and then disply that variable which should be my rs232 string in the message box. I have also added "Cmd" to the variable names above so I also need to work out how to add the text "Cmd" to the string to properly compare.

Private Sub Musicbtn_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles WatchTvbtn.Click, VolUpbtn.Click, VolDownbtn.Click, SystemOffbtn.Click, Radiobtn.Click, Musicbtn.Click, GardenVolUpbtn.Click, GardenVolDownbtn.Click, GardenRadiobtn.Click, GardenOffbtn.Click, GardenMusicbtn.Click, GardenMediaCenterbtn.Click
Dim labelname As Label = DirectCast(sender, Label)
[Code] .....

.net - Friend WithEvents In VB Vs Private In C#

Who knows, why in WinForm projects the designer by default use the Friend WithEvents attributes and in C# - private ones.

By ex, in a form.designer.


private Label Label1;


Friend WithEvents Label1 as Label;

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

.NET Visual Inheritance: Friend Versus Protected?

Jun 18, 2010

Why 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?

Use A Private Class And It's Members From Another Class?

May 18, 2009

I usually use which is free, works a little too well, it's obfuscating the code that passes between my scripting class and the other classes, so after obfuscating the app, the scripting functions no longer work.However I found another obfuscator called Skater lite which is a free edition, it will only obfuscate private classes and members, so what I would like to do if possible is make most of my classes private and their members (except for the scripting class, which should allow it to work properly after being obfuscated), and somehow still use them globally, declaring an instance of the class doesn't seem to work, I'm not even sure it's possible and I know little about the scope of private classes, so anyone got any ideas or workarounds?

Change The Default Modifier From Friend To Private In The Windows Forms Designer In VS 2008?

Jul 2, 2010

When 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.

How To Make A Class Instance Public

Aug 21, 2011

Is there any way to make a class instance public?In my mainform I define an instance of a certain class and then later on in some other forms which appear I want to alter this class.I try and pass them through when creating new instances of these other forms and it tells me Error3<instance of the class I want> cannot expose type <the class> outside the project through class <the form I want to edit it with>Which I gather from documentation is about it defeating the purpose to have a private class suddenly be thrown aroudn.but then how do I make it public? I can't define it in the first place as public myXClass as XClass, it only accepts private.

Make Constructor Public And Allow Anybody To Create An Instance Of Class?

Apr 6, 2009

I have a class inside a class.I need to expose the properties of the 2nd class to other classes, therefore it is public.However, I do not wish other classes to be able to create instances of this 2nd class, it should only be instantitated from its parent class.I thought I could resolve this issue by making the constructor of the 2nd class private, but this even prevents the parent class from instantiating its child class! How can I work around this, do I have to make the constructor public and allow anybody to create an instance of the class?

Protected Error In Compile Time, When No Protected Class Is Used?

Nov 10, 2011

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?

Protected Constructors And MustInherit / Abstract Class

What is the difference between a class with protected constructors and a class marked as MustInherit? (I'm programming in VB.Net but it probably equally applies to c#). The reason I ask is because I have an abstract class that I want to convert the constructors to shared/static methods. (To add some constraints). I can't do this because it's not possible to create an instance in the shared function.

VB Class (class File - Not School Class)

Aug 9, 2011

so I used to mess around with C#, just a little. And someone had helped me make a class for Visual C# that was supposed to do the math parts for "internal structure" - which the program used for a part of its calculations and screen... Basically there were 2 options. Endo-Steel and Standard. The user would use a updownbox to determine weight of the machine and then internal structure was a % of that total. If it was standard then it was 10% of the overall weight, if it was Endo-Steel then it was 50% of standard (so 5% of total weight) rounded to next 0.5 (so .25 was .5, 1.25 was 1.5, 1.75 was 2.0, etc). I have the code for the C# class file for it, but want to make it in VB.
