Loop To Search For Duplicate Numbers Within A Column In A Database?

Nov 28, 2011

i have wrote a loop to search for duplicate numbers within a column in a database which i have got fine but when i find a duplicate i would like to get the all of the row so if 33 was a duplicate i would like to get the following row.

33MarkWhitesideM12/07/1958Michaeluuu

I have tried to do this buy use something i saw on msnd's website:

Dim foundRow() As Data.DataRow = customerDS.Tables("Details").Select("HNCNO Like '33%'")

However if i change the line to notice the i beside the like

Dim foundRow() As Data.DataRow = customerDS.Tables("Details").Select("HNCNO Like 'i%'")

but i get Index was outside the bounds of the array. Ok i know that means that there is nothing in my array. What i would like is to find the duplicate row associated i. you will probably understand me better when you see the code.

Private Sub checkRowsForDups()
Dim customerDS As DataSet
Dim dupArray As New ArrayList

So basically I'm making a BINGO game on vb 2008 and i have a "call number" button. The letter and numbers get added to a list box each time. But i do not want the same number to be called.

Callnum = Int(75 * Rnd() + 1)
lstNumbersCalled.Items.Add(lblCallLetter.Text & " " & Callnum)

Removing Duplicate Numbers In Listbox?

Jun 10, 2011

I have been working on a pythagorean theorem calculator and am actually stuck on the final bit of code. What I am trying to do is check the values (integers) inside a listbox, remove duplicate number (both values), and input one of the values into a textbox.

Here is an example of what I am doing:

LISTBOX VALUES
2
2
3

[code]....

When the program runs, check listbox value #1 and listbox value #2, if listbox value #1 and #2 match (2 & 2), input that value (not both duplicates) into a variable, remove both of the duplicate values, continue checking the rest of the values, and finally multiply the leftover values. I am sure that sounds confusing. Here is what the final output will look like

LISTBOX VALUES
3
7

Create A Loop That Duplicate A Label?

Mar 7, 2009

I'd like to create a loop that dupliates a label I've made and put it all over the screen. Example of what it would look like.

For i = 0 to 52
originalLabel.duplicate ("duplicatedLabel" & i)
next i

So later I could go through all of them...

For i = 0 to 52
//... some logic to determine color... then assign it somehow
duplicatedLabel & i.backColor = Color.red
next i

[code].....

I can do that in Flash/Actionscript but dunno how to do it in VB and I can't find it anywhere.

Duplicate Existing Form In FOR Loop?

Jun 26, 2010

I'm building a code editor app in VB.NET (Framework 4.0) and it opens all ".por" files into individual forms consisting of a MenuBar and TextBox (multi-line).Currently I have 20 forms (all duplicates of the first on I designed) and if there are say 4 ".por" files in a directory, the first four will open up while the others hide.

I think it would be far more efficient by coding a new form For each item in form1's ListView...but I want the next so many to be a copy of the first form I designed since I spent a good bit on it.

Datagridview - Sort Datagrid View Column With Numbers And Texts On Column Header Click?

Feb 13, 2012

It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?

Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?

VS 2008 Loop Causing Duplicate In List Of String?

Aug 21, 2009

Basically what happens is each time it loops through it adds a number to the end of the string, and by the end I should end up with an array full of string in a format like "111 222 333 444 555 666" but I end up getting strings like this "111 111 222 222 333 333". The weird thing is, if I add a message box in every loop it works fine, but obviously I don't want a message box pooping up every time it loops through. What is causing this and how might I fix it

The code is:
For x As Integer = 0 To (NumCards.Value - 1)
NumRep = 0

VS 2005 Duplicate Column Name .txt File?

Jun 7, 2011

I have a program that reads a 3rd party .txt file using OleDB into a DataTable When it reads it, its creating a column alias name, and works fine.

gives the user the ability to save a record to the .txt file by using an OleDb command statement and inserting a record into the DataTable then I re-write the file using stream writer because my understanding is you can NOT write directly into the .txt file.

I have created the program to read column postion rather then name since some data providers call columns different names, but I havent encountered a provider using the same name for 2 different columns.
