Duplicate Elimination - Diplay It In UniiqueValuesListBox?
Oct 9, 2011
I looked for code snippets online to do this project, have not really found any elegant code snippets except for this one.My project is to use a one-dimensional array to solve following:Read in 20 numbers, each of which is between 10 and 100 inclusive.As each number is read, display it in NumbersEnteredListBox and if it's not a duplicate of a number already read, diplay it in UniiqueValuesListBox. Provide "worst case" all 20 numbers are different.[code].....
I want to understand what I'm learning so it will stick. What is Ubound? I realize I need to rewrite some of this to fit to what I'm trying to accomplish, but I want to understand it first. This is not in the book thus far. The codes I have found were sorry...horrible...I want to learn to write better with less words if possible?

how to use a Dim numbers() As Integer thats bout it here is my problem that iam facing :Use a one-dimensional array to solve the following problem: Read in 20 numbers, each of which is between 10 and 100, inclusive. As Each number is read, print it only if it is not a duplicate of a number already read. provide the "worst case" (in which all 20 numbers are different). use the smallest possible array to solve this problem.

As a beginner I am unable to find how to diplay decimal in my DataGridView.
I am using VB 2010 And using access 2010, I designed my database and set the following
Set Data type to Number. Field Size to Decimal Format to 0.0 Decimal Places to 2
When the DataGridView is diplayed on the form, all the decimal's are rounded to integers.

I've seen this question posted a few times but no good results. I'm simply loading a dataset from access that happens to have a bitmap stored in a field. I have a listview with a list of CD's by Album/Artist, when I click on one of the CD's I want detailed info to populate below, including a pic box with the stored bitmap. Everything works fine except the pic box. [code]...

I Use visual Basic 8.0 and Mysql 5.0 I have two exactly the same Tables:
Table1:
RecordID , Integer = primary key auto_increment NOT NULL
Articlenr , Integer
Articlename, Char(20)
[code]....
I want to add all the records from table1 to table2. I want to do this 10 times if I execute the following statement: INSERT into Table2 SELECT * FROM Table1 ; Everything works perfectly. The two records are added to table2 But if I execute the stament a second time get the following message: Duplicate entry '1' for key 1 I now i must do something with "duplicate key update" in the Insert statement.

i have this sql table
Table name: Project
Fields: PrjCode, PrjName
i want to save my Project codes and name to this table, but before i will save the data from my form i want to check if the user input (PrjCode) already exist in the database. and if the prjcode exist it should not allow to save the entry since it will duplicate. (NOTE: ProjctCode is not auto number. the user will input it)
base on this scenario have this code
If PrjCodeTextBox.Text = "" Or PrjNameTextBox.Text = "" Then
MessageBox.Show("Please Complete the information required!", "System Message", MessageBoxButtons.OK, MessageBoxIcon.Error)

I have a List(of String). For example: {"C1", "C12", "C10", "C1", "C6", "C22", "C1", "C6"}. I am trying to write a function to give me a list of duplicates: {"C1", "C6"} in the list. Each duplicate will be listed only once. The function I wrote does give me anything back at all. I can't figure out why. how to translate that syntax into VB.net since I am not up to speed on LINQ yet. It is here: How to get duplicate items from a list using LINQ?
''' <summary>
''' Given a List(Of String), returns a list of items that are duplicated in the list.
''' Each duplicate returned is unique.

I'm designing a web page with two dropdownlists, one for the Make of a car, the other for the Model, both bound to a database with separate SQLDataSources, and using a distinct statement. I add "All" at the top of both by setting appendDataBoundItems = true and adding items named all. Then when I fill the Make with a querystring all the model items get added twice (but only the databound items).
Here's my code:
<asp:DropDownList ID="DropDownMake" runat="server"
DataSourceID="SqlMakes" DataTextField="Make" DataValueField="Make"
AppendDataBoundItems="True" EnableViewState="False" AutoPostBack="True">
