How can we apply attributes to class fucntion using AOP in C#?I am slightly not clear in what context AOP should be used? As we can use AOP for logging purpose, security(Authentication), please suggest some other scenarios where we can take benefit of AOP.Is AOP can be use to share data among different running threads in application process?

I recently posted a problem with a game that I am making, I have worked on it but have become stuck. I am having trouble with creating an object from my class what I need to do is apply this class to multiple picture boxes so that I can have them moving on screen at the same time. I am unsure on whether or not I have set up the class correctly and am unsure on how to apply it to multiple picture boxes.
This is the class:
Public Class enemycar
Inherits PictureBox
Private speed As Integer
Private xposition As New Random

I want to invoke a method on a class that i have a reference to. The method that I want to call has a custom attributes. Currently I can find this attributes and call the property of my class Attribute.
is there a way to invoke that method ?
PS/ The project is written in vbnet, but I think the solution is the same in c#.
I'm just curious why class/property attributes in VB.NET have a weird optional syntax such as:
<TestAttr("a", "abc", Optional1:="foo", Optional2:=3)>
VB.NET allows you to set optional parameters like this to avoid order restrictions (which is lovely) but in this case it's forcing you to that.For example this is not possible:
<TestAttr("a", "abc", "foo", 3)>
even though the parameters are in the same order as the original definition.

How can I read the custom attibutes of the CustomerID or any other property?
I have an API that I created and currently utilize successfully in C#. I am trying to create an example of interacting with the API in VB.NET (so that the QA without C# experience can still utilize it for creating automated tests).
In C# I do the following
[TestingForm(FormName= "Land Lines", CaseType= _caseType
, Application= ApplicationNameCodes.WinRDECode, HasActions= true)]
public class LandLines : RDEMainForm
[Code]....
This gives me a compile time error because it claims that FORM_NAME and CASE_TYPE is not defined, even though the class has it defined inside.
How can I use the defined constants inside the class in the class attributes?
I am trying to retrieve the Attributes of a class's property specifically. So for example. Let's say I have a class called "Employee", and a custom attribute called CustomLabelAttribute with a string value. What would I need to do to retrieve the value of CustomLabelAttribute for Employee.FirstName specifically? I assume I will need to use reflection, but it's kind of new to me, and I've just recently started using it on any level.

I was knowing that For Each loop can only be applied to those classes that implement IEnumerable interface . But recently i accidentally wrote a code that is using For Each on my class's objects collection and my that class is not implementing IEnumerable interface .Below is the sample code that i am testing on :

Dim personList() As Person = New Person(2) {}
personList(0) = New Person("s1", "s2")

So my question is, I'm wiriting a VERY basic dice rolling program for my computer programming class in high school. I'm using a randomize function to generate numbers but I only want it to do numbers 1 - 6....how do I do this?
Dim x As Integer
Randomize()
x = CInt(10 * Rnd())
Dim Y As Integer
Randomize()
Y = CInt(10 * Rnd())
That is my code for my x and y (each die) to generate code, but how do I make it do 1 - 6 ONLY? Develope a game that in which a player rolls two dice. Each die has 6 faces. Each face contains 1, 2,3,4,5,6 after the dice have come to rest the sum of the spots is calculated, if the sum is 7 or 12 on the first throw, the player wins. If the sum is 2,3, or 11 on the first throw, the player loses, and the house wins. If the sum is 4,5,6,8,9,10 on the first throw the sum becomes the player's point. To win, a player must roll the dice until the plater rolls the point value. The player loses by rolling a 7 before rolling the point. I also have another question, How would I set this up to keep up with points and stuff? and the part that says "The player loses by rolling a 7 before rolling the point." I have no clue what to do on that. I'm not asking for code hand outs. I'm just asking what functions and such I'd use to write the code.
Simple thing, well, I think it is.I need to Add a class to an element within an asp:repeater under certain conditions, using VB.
So, I can do
ITEMID.Attributes.Add("class", "classToAdd")
But this removes the existing classes and therefore screws up my CSS.

I have two user controls that need to add a class atribute to the body tag of my page, however they currently over write one another if I just use Body.Attributes.Add("class","value") So I need to check if the class attribute exsists and if it already contains the value Im going to add.
If Not Body.Attributes("class").Contains("value") Then Body.Attributes.add("class", Body.Attributes("class") + " " + "value") End If
EDIT: The contain constraint doesnt return the expected value, resulting the the class not been concatinated, Example: add class "dog" then I a different instance of the same control tries to add "dog" but the contains("dog") returns false
If Class X is within the scope of Class Y, is X a subclass of Y?If Class A is a sub Class of B, then is Class B considered a super class of A?if Class C inherits Class D is Class D a superclass or parent of Class C?if Class E extends Class F then we can consider Class E a child of F?if Class G inherits Class H and is within the scope of Class I then who is the parent of Class G? Classes that inherits Class J and classes that are within Class J are all sub classes of Class J?
View 1 RepliesI code GUIs in .NET frequently, and most of them only have the value of being a GUI, e.g. they don't do anything otherwise impossible. So most of the development goes to making them friendly, intuitive and eye-candy.Then it comes to my mind it would be simply amazing to skin them through .msstyles files, since there are so many places to find those files, and also tools to make your own.And some of those msstyles are just stunning, probably not for your whole desktop, but for styling homemade apps it would be perfect.
