Add Randomness To Objects?
Dec 20, 2011
I want to start by saying that I am very new to programming so please be take this in to account when responding.
I am trying to finish my masters thesis and have to run a small program to assess how individuals can rank several different patterns on the basis of how random the pattern looks.
So i need to create patterns with varying degrees of randomness. Some with very little randomness and others that are completely random.
The way I thought I would accomplish this was to make the pattern out of a bunch of smaller objects or primitives. Then call out each object and then add in a random displacement to the object. For increasing randomness increase the amount of displacement (scale within the RNG?).

I have a program like this.
Module Module1
Public Class Mstr
Public Property Prop1 As String
Public Property Prop2 As String[code]....
But it is not working as I expect it to. You can see it from.The DtlsB properties of all three DtlsA objects are having values from last iteration.

long story short, I have created a ListView type control, using UserControls for the parent control and the ListViewItems. Most the of the control is written and works fine, right up to the point where I tried to replicate the 'Control.SelectedItems(0).Index' property and the 'SelectedIndexChanged' event.
Each child object knows its index value, and could pass this value via the SelectedIndexChanged event (assuming this is how it works in a normal ListView control -- user clicks on an item, and that item fires an event updating the selected index value in the parent object).
How does the child object raise an event in the parent object? I have a feeling this could be done with Delegates, but I'm still learning about their usage.

I have a nested class, let's call it class1 and it has class2 inside it; VB.Net eg:[code]
1) How can I define X number of Class2 objects[let's call it: Node(x) array]** with NEW() subroutine called?' this raises error: dim cls2(n) as new class2 end sub.
2) How can I return actual number of Node() array? [code]Outside my class in main project I define cls1 object:[code]Now an array of class2 is created inside cls1.
3) Now,How can I access All of them[node(x) array which is created inside cls1] with all properties and methods available?
I remember I wrote a ProcessManager class with this functionality in .net 2003, nearly 4 years age, I don't have the code now.

I need two seperate lists, which every item is Integer, String, Bitmap - and one which every item is Integer, String String. However I don't know how to do this, or even where to look - I've googled for custom objects and custom object lists. What I'm trying to do is this.Custom Object1 is Integer, String, Bitmap Custom Object2 is Integer, String, String
In one thread I'll be adding items to List1(Of Object1), and processing them, and adding the results to List2(Of Object2), however I need to be able from other threads to look at the list and say only give me the items where Integer = (my thread ID), is this possible? Any help, or even links to information that would be relevant to this request would be helpful?

If you have a sqlClient.sqlconnection object, in the cleanup code (finally block etc) do you dispose of the object or do you set it to nothing, or both?
I've always just called the dispose, and allowed the garbage collector to do its thing...

The 1st part of the code required me to write a class definition for a class(Worker). The class should include Private variables and Property procedures for a worker object's name and salary.
The salary may contain a decimal place. The class should also contain two constructors:a default and a parameterized.
The second part for the code indicates that I need add a method named GetNewSalary to the Worker class.The method should calculate a Worker objects new salary, which is based on a raise percentage provided by the application using the object.
Before calculating the new salary, the method should verify that the raise percentage is greater than or equal to zero. If the raise percentage is less than zero the method should assign the number zero as the new salary
There are three text boxes which allows the user to enter the employees name current salary and raise percentage....the calculate button will display the new salary in the new salary label box...so far here is what I have for the worker class.
The Class for the code had to be written from scratch. Can you please look over the class code and see if I need to chang anything....that will allow the program to run.[code...]

I'm coding a restaurant program where every table, server and guest is a different object - Is there a right way of getting objects to communicate with each other?For example, one server might have 5 table objects, each table might have 2 guest objects. Is there a way to neatly tie all this information together. If a guest moves to a different table I have to change a large number of variables (number of guests served by server, table set to empty, new table sat...etc etc.)?

The error I am getting is:[rb#] "is not declared. It may be inaccessible due to its protection level"

The plan is to use a database just a MDB one, which holds all text fields for all the objects in my application.For example (real dodgy example)Label1.text = "Select NewText from Table where [ID] =" & Label1.Name & " and [ENABLED]=1"..I want this to go for every single control in my application, which basically would allow any client to completely customize text fields in the app.Currently I'm using this so far to access the Data. But before I continue I want to see what you guys would do?[code]

Dim c as Collection = new Collection
c.add(new A)
