For a school project I need to create an application one element of that it puts 14 names into a random order, I figured the best way to do this was with an array and a for/next loop (it cannot repeat the names) each name would be declared as a string with the name of the variable being a number between 1,14. Then there would be a text box relating to each index of the array, I am sure you get what I mean. However, my for/next loop seems to be getting stuck and causing the application to halt and I cannot seem to work out why.
Here is my code.
Public Class Form1
Dim iNumber As Integer
Dim arrNumber(0 To 13) As Integer
Public Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
[Code] .....
I have yet to write in the section which converts the random numbers into the names, as I discovered this error whilst debugging the for/next loop.

When I have changed the name of a table field name none of my combo boxes or grid views work properly. The TableAdapter still refers to the original name. Is there an easy way to make the change propergate through the program or do I have recreate all my TableAdapters.

This next program I am working on consists of 3 listbox's. The idea is to have the end user load names in the first and second list box. Then have a button's action when pressed combines the list in listbox1 with listbox2 then gives the output combination in listbox 3.
I also wanted to include some checkbox options such as adding a "_" or "." for every item.
Here is a thinking map of how I want it to work.
Listbox 1

Listbox2

create a generic list of strings

I am trying to create a few random numbers, but cant seem to get it to fire off.
Public Function GetRandom(ByVal Min As Integer, ByVal Max As Integer) As Integer
Static Generator As System.Random = New System.Random()
Return Generator.Next(Min, Max)
End Function
When I call the GetRandom(0,500) and display it out on the page, I don't get anything?

I am a newbie programmer and I need a way to generate random numbers for a program I am working on. It just needs to be something simple that generates a number and allows me to assign it to a variable. I would like it to be something small say 1-10 would be good and an explanation of the syntax would be helpful

Okay, so the title was horrible. I know that. Here's what I'm trying to do:I have a lot of data that's coming from a database and being adding to a listbox. The data that's coming from the database is a unique ID, and a name. Is there any way I can make the item contain both the ID and name? I know I can append it, that's not what I'm looking to do. I need a way to be able to either get the ID, or get the name, while displaying them both.I have gotten as far as creating a class:
Class Item
Property ID as Integer
Property Name as String

I don't usually use VB but now I must for an assignment. I would like to know if it's possible to change the display name for an object on a listbox. For instance, if I add to it a user defined class, there's a way to provide it's display name, instead of converting it to string and then add it.
This is what I have
Dim format As String = FormatOutput(object)
Lista.Items.Add(format)
I would like to have the same output, but instead add the object.
Note: if such is not possible, then how can I associate the list box selection to the actual object? Doing it by index is painfull, because I'm using linked lists (ie., instead of arrays).
Note 2: python has a __str__ method which is called by default when the object is cast to string. Is there anything like it in VB?
