I have a user control that inherits the FW ListView and I need to dispose of two objects when the form's disposing of it's objects. Here's what I've concluded already, am I on the right track?
[Code]...
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.
getting the following error Unable to cast object of type 'System.Object[]' to type 'OrderService.webdirect_WebLinesRow[]'. On the line
webdirect(web_companyID, web_locationCode, web_customerNumber, web_orderNumber, web_orderReference, web_orderDate, webLinesArray.ToArray(), o_Company, o_LocationCode, o_CustomerNumber, o_OrderNumber, o_OrderStatus, o_OrdDescrip, webRespArray)
I created the webLinesArray.ToArray() array as such
Dim webLinesArray As New ArrayList()
Am I missing an additional cast or something ?
I want to compare two objects to check if all the properites of both the object have same value or not. for this i need to use the reflection to enumarate through all the properties of an object and check the value of the property.

View 1 RepliesI 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?

I have students who will be enrolled into a course. The student grid view has many columns like client_no, student_name, date_of_birth, address, etc. There are over 100000 students so I will need to filter the student grid view to find the correct student to enroll in the course. Once they are found, the user selects them and somehow moves them to the enrolled grid view. If a student drops out then they would be removed from the enrolled grid view.This process needs to be easy to understand and use. Are there any examples available or other suggestions on how to do this?

How do I handle nested collections, for example, the Placemark collection in this example?
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?).
