VS 2005 TextFieldParser Duplicate Column Name
Sep 29, 2011
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)

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.

Does this mean the water in a pond is not abiotic but pure water is?"The following from the MSDN help that works:

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 am sending values from Combobox and Textbox to Access Database in VB.NET.I am phasing the problem when i enter the Duplicate values.In the database one of the column is Indexed.(Yes Duplicates not allow)That column i bind to Textbox("txtperson1").I used the TRY and Catche method to solve the Indexed Problem.when i run the application the value which i enter is not a duplicate that value save on the db. Once i enter the Duplicate value , the message box is showing "The Record alread saved".But After i enter the new value the same message is displaying, it is not saving on the db.

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.

It seems like in order to use "TextFieldParser " you need to include the path of the file to be parsed. Is it possible to use OpenFileDialog1 and then choose a file? I keep getting error messages.

I'm currently busy coding a hangman game in VB.NET.As a wordlist, I have a textfile containing 1520 words, each one seperated by a new line. The best I could think of to get a random word is with a Randomize() function. Then getting the word from the line # which was randomly generated.
[Code]...
Is there any better way for me to extract the word from that random line? If not, what would be the delimiter I should use for this and how do I quickly change the breaklines into that new delimiter without resorting to Office?
Also, how can I use the textfieldparser to get the file from resources? When I tried using my.resources.filename instead of "filepath", it gave me an ArgumentException due to "invalid characters in the path".

Ok so I am taking jm advice and using TextField Parser instead of ADO.net to read my delimited files and then build my own datatablesFirst question is how would I query the data?I need to be able to have two tables, one with sold propertys and one with propertys still for sale.The table I created thus far has all the records, the problem and my second question is how do you allow for a null value ?If one of the records isnt Sold then it won't have a Selling Price therefore when I set my datacolumn to be of System.Integer type It is not accepted

I'm using the following code to read some values in from a tab delimited text file:
vb.net
Using Parser As FileIO.TextFieldParser = My.Computer.FileSystem.OpenTextFieldParser(LogFile, vbTab)
Parser.TextFieldType = FileIO.FieldType.Delimited
Dim comments(0) As String
[Code]...
As you can see I have set the HasFieldsEnclosedInQuotes property to true on the textfieldparser because I want to make sure I capture the data correctly if quotation marks are used. If I set the HasFieldsEnclosedInQuotes property to False then it all works (or at least it doesnt error anyway) but like I said, I need to have that set to true because otherwise if the line contained a tab character within the quote marks then my app would think this was two separate fields and process it incorrectly.

Is this class normally slow or maybe there is something in my process making it slow.I have to import 170,000 rows of data from a fixed length text file into a SQL table. It takes about 2 minutes in a DTS package on SQL server 2000. But we are migrating to a SQL 2008 server and since this code has several manual steps and does not manipulate the data I thought it would be easier to use the TextFieldParser object to handle reading in the data.
Here is the code:

I have a VB2010 project where I need to read a tab delimited 50MB file using Microsoft.VisualBasic.FileIO.TextFieldParser. This technique works fine until the reader encounters a Unicode character upon which it inserts the little square thingy. The obvious choice is to change the encoding of the reader to Unicode from the default. This would probably work fine but for most files but this one is fairly large and I get the error TextFieldParser is unable to complete the read operation because maximum buffer size has been exceeded. By the way this file can be read completely without the Unicode option. Making the file smaller or breaking it up really isn't an option. Is is possible to increase the buffer size or is there another way to read this data that places the data in fields like the textparser and allows unicode characters?

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 using VB.NET's TextFieldParser (Microsoft.VisualBasic.FileIO.TextFieldParser) to read a delimited file. However, when I try to read in a field with consecutive newlines within the field, the consecutive newlines are turned into a single new line. I would like the consecutive newlines to be preserved, but am unsure how.Here's an example file that I am reading in with exactly one field. The quotes are part of the file's content and there are three newlines (including the two consecutive newlines following line 2):
"This is line 1
This is line 2
This is line 4, which follows two consecutive newlines."Here is the code that I am using to parse and read in the file:
Dim reader as New Microsoft.VisualBasic.FileIO.TextFieldParser(myFile, System.Text.Encoding.Default)
reader.TextFieldType = FileIO.FieldType.Delimited
reader.SetDelimiters(",")

The end of the text document my application is reading is denoted by a character that I cant identify, copy or paste. I attached an image of it so you can see. I have no control over the formatting of the document so I can't change the character. During debugging it shows the same character as shown in the picture, but if I hit the little tack next to where the variable shows then it changes to "f". However, if I try to see if the variable equals "f" it returns false.
