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.

I am using the TextFieldParser to read a 3rd party .txt Tab Delimited File Sometimes the file contains duplicate column names and subsequently I cant create my DataTable.
How can I check for duplicates first and change the name of the duplicate fields so I can populate my Table?
Example:
I have two columns called ST and would like to Change of of them to ST1 or something similiar to populate my table
Dim safeFileName As String = IO.Path.GetFileName(Me.OpenFileDialog1.FileName)
Using myReader As New Microsoft.VisualBasic.FileIO.TextFieldParser(safeFileName)
myReader.SetDelimiters(vbTab)

This is my programs complete code, the only problem is i want to fix the amount of decimal places that show up in my gridview. The problem is if i do this on the asp side the location of the column gets thrown off and the column is duplicated. I figured if i just remade the table on the asp side it would work only problem is if i remove the sql for that particular column the asp side column cannot get data.

i am checking for if the column code is Null or not in that same i wnat to check whether the column has any of the duplicate values then i should mark as isGoodRecord = 2,
If (IsDBNull(Row.Code) Or Row.Code = String.Empty) Then
Row.IsGoodRecord = 2
ErrorDesc += "Code is blank;"
end if

I have a gridview where I need to have column names within 1 sortable pageable gridview as the same name, but when I set up the sql query as
select x as 'col', y as 'col', z as 'col'
it shows up in the gridview with autogeneratecolumns on (theres a lot of columns in the page I don't feel like not autogenning it)
and it shows up as
col
col1
col2
in the gridview but I want it to just be col, col, and col. I understand that this could cause a sorting problem without turning autogenerate columns off, but I was hoping there was some type of work around.

I am trying to create the code which will stop duplicate entry of an Account Number being entered in the column 'Account Number'. The user is to input an account number (three digit account number i.e 153) using an input box and this will then be printed into the A column.What is the best way to prevent duplicate account numbers being entered?
The code I have for the input/account number array so far is:

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

I am working on DataEntry Forms in VB.NET There are two controls are having in a present window. One is Combobox and one is Textbox. Combobox values are Mobile, FAX, E-mail. By the mistake some one enter the values like , In the combobox-E-mail and in the Textbox-9987453434. Finally these are saved on the Database. But i want to Re Enter the values.
For this i was selected in the Combobox-Mobile and in the Textbox-9987453434. These are the right values i want to save on the database.
But here the problem is that Phone number column(Textbox) is Indexed. (Unique) or No Duplicates in the database. Now i want to update only one column which is coming from Combobox in the database.

I have two text files, the first text file has two columns separated by a space (" ") and the second text file only has one column.
The column 1 in text file 1 and text file 2 match albeit in different order, what I'm trying to achieve is for every field in column 1 text file 2 I want to search for column 1 in text file 1 and display the matching column 2 field in column 2 text file 2.
Dim*OpenTextFile*As*String*= IO.Path.Combine("C:Test1.txt")
Dim*OpenTextFile2*As*String*= IO.Path.Combine("C:Test2.txt")

I want to make a very simple program that remove duplicate domain name from a txt file. First, it must have a Open file Button so that it can load list of url to Listbox.
So, the URLs will be loaded into listbox. Then It has 2 more button Start and Save button Lastly one counter to calculate how many URL in that listbox
So example.. let say I have a txt file which contains URLs
[URL]
I open this txt file and loaded it into listbox (can scroll)
Then when I press start button, it will delete the URL that has same domain name. so the output will look like this
[URL]
Then I can save the URL from listbox to my disc drive as text file

The problem at hand is to search an Access database for "duplicate" street addresses, given user input of street address, city, state, and zip code.Given the zip code, city and state do not need to be looked at.
My thought was to select off records in the database with the zip code that matches the input, then loop through those records, performing a "similarity" test on the street address field as compared to the input street address. Obviously we cannot test for exact matches (i.e. "SW" vs. "South West", etc.). This problem has obviously been solved before with post office software, algorithms used by mapping applications, etc.
But do you have any thoughts on what algorithm I might implement in a VB 2005 app?

I am adding line entries in a .ini file. The problem is, I am creating duplicate lines in the file, which I do not want to do. I searched this issue online, and the consensus is to use an array, loop through for duplicates and create a new file. However, being so new at this and teaching myself how to code no less, I am at a dead end. This is not a school project, it is something I am doing for work on my own time. I have all of my code done for the program except for this last step.
