[2005] Working Of Friend Class With Public Methods?
Feb 27, 2009I 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.
View 4 Replies[2005] SyncLock And Multithreading - Public Class Utilities With A Many Shared Functions
Feb 11, 2009I am trying to get a handle on SyncLock and multithreading, but I am having some trouble wrapping my head around exactly how it should be implemented. I have a Public Class Utilities with a many Shared Functions. I want to make sure that each function can only be executed when there are no other concurrent calls to the same function. So If I have 2 functions, A and B in a Public Class Utilities, what is the syntax so that a function "locks" while it is being executed, preventing any subsequent calls until the "locking" thread has completed?
CODE
Public Class Utilities
Public Shared Function A (ByRef i As Integer) As Integer
[CODE].............................
I know I need to wrap the statements of execution in a SyncLock block, but I am unsure of the scope of the parameter used with SyncLock...is it private to the function, class, etc? Can the same object be used to lock both functions if they are independent?

.net - Using A Class Like A Public Variable In Asp.net?
Apr 13, 2009I'm getting an error in .net when trying to declare a Public class on my code behind page.

Public someVariable as integer
Public someClass as className
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load [...]

I'm not sure if I'm trying the right methods (I've tried several ways of declaring the public class) or if it can even be done..
