View 1 RepliesI made a program to generate random numbers and the result will be in two boxes. The first box contains 16 numbers and the second one contains 32 numbers. I need to add a diagram show the relationship between these numbers. The diagram must contain ten fixed objects numbered from 0 to 9 and the code should start reading from the result box from left to right. for example: we have a result [1502219785642556], so object number one its color will be changed to be known that it is the first number then the second number is five so there will be an arrow goes from object number 1 to object number 5, then arrow from 5 to 0, arrow from 0 to 2, from 2 to 2 cycle arrow.It better to designee the objects in three rows and columns, and each arrow has a number in sequence.

View 6 RepliesThis probably sounds daft, but im struggling to get to grips with Classes/Modules/arrays and objects, as well as there uses and what they are, and yes im still coding some how i hear you cry.The reason i ask is because Ive got a load of Dim's in my program that are the same giving locations of files and folders and wondered can they be used as a module that i can alter after the program is built, incase of folder locations being wrong or moved, manually correct after install.

I wanted to ask you how I can make vb 2008 connect to web forms, fill them out & submit them all from vb 2008 objects/fields.

I am trying to find information on code to make the lines of a jpg file that have been loaded into a VB.NET WebBrowser control into selectable objects.
I have no idea what to search for or the correct terminology.
This is very similar to using the line tool in word or excel, after you draw a line you are able to select it.
Okay I've been wondering about this for a while now, but whenever you assign variable values to objects they tend to just become references to the original object
For example:
Dim copiedCollection As ListBox.ObjectCollection = ListBox1.Items
For Each L As String In copiedCollection
If L = "Goodbye" Then ListBox1.Items.Remove(L)
Next
As soon as it encounters the string "Goodbye" and removes the item from the listbox, the program will throw an error saying the the collection (copiedCollection) has been modified. How can I make copiedCollection a true copy (not a reference) to the Listbox1.Items collection?
I am getting this error, Not sure why it is happening "Error The SqlParameterCollection only accepts non-null SqlParameter type objects, not Int32 objects."I have tried with all sorts of possibilties, now try to enter default data as dummy data,

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.
So I am trying to make a program that allows you to move two shapes using two KeyPress events, one to move the first object and another for the second. It works, but it can only move one of the two objects, not both at the same time.

as per usual i am a little confused. I know DownloadStringAsync runs on a threaded pool with a default min and max threads limit, but what confuses is how would i call DownloadStringAsync say for example ten times.Example.I have an array with 10 URLS. Surely i would not use a for each loop of the array index to pass the url address while each time calling DownloadStringAsync(New Uri("someArray(index)") surely we can pass say a range of items from the array and let DownloadStringAsync decide on the threaded pool how many to process each time?
View 6 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?
