I was trying to read Quote-delimited file using VB TextFieldParser. It doesn't work. However it seems to work if I set the delimiter as comma (","). How do I read quote delimited file?

How to read a comma delimited text file? I want to have a new line for each row. For example it would be (author,book,location).
View 11 RepliesI'm having a problem where instead of reading a text file from the location string, I changed it to read the text file from the resource location and it breaks my program. I've also used the insert snippet method to get most of this code, so it is safe to say I don't know what is going on. [code]
View 2 RepliesWhen I use to do some Delphi programming you were able to define variable as a target for a comma delimited file and then under that give variable names for each field to fall into. I forget the syntax now but it looked something like this...
Using Getline as Record:
RecordId = Integer
RecordName = String
RecordAddress = String;

So i'm new to working with vba in access and i'm having trouble getting this code to work. What it is suppose to do is take a selected text file and read the original file into a list box. Then there is a second button that when pressed will convert the text file from a pipe delimited file into a tab delimited file and then show the changed file into a new listbox.
Option Compare Database
Option Explicit

I have a CSV file where the values are in double quotes and seperated by a comma. I'm getting incorrect data if I try to seperate the string with my Split function. How do I do it?
Example:[code...]
I am trying to replace "a" to = ""a""
code i have tried is
If line.Contains("""") Then
line.Replace("", "")

I have a text file with ";" as a delimter but I am not able to seperate the text, I am able to read one line at a time using ReadLine Function but I can not find a way to separate columns from this line.
View 4 RepliesAfter some thinking, I think I figured out how to read delimited text. I was just curious as to whether it'd be better to use StreamReader.ReadLine or File.ReadAllLine or if it matters at all? I'm assuming the ReadLine method would be better if I'm working with a larger file since ReadAllLine would store the entire thing in memory? Here's my code - I'm reading from a text file and displaying into a listview.
File.ReadAllLines
Dim lines() As String
Dim parts() As String
lines = File.ReadAllLines("C:lah.txt")
For Each line As String In lines
parts = line.Split("|")

I want to extract a line and take the Name and separately and the ints separately. Then I want to print the name and the average of the numbers like this in a label: John's average is 90 Micheal's average is 70
So far I can only display what is in the text file in a label (see below):Dim FILE_NAME As String = "C:ExamMarks.txt"Dim TextLine As String If System.IO.File.Exists(FILE_NAME) = True Then

View 2 RepliesI'm trying to read a csv file with comma separated. Problem is inside the file, it has one column which original value already contains Comma. Here is the example
[Code]....
So, when I Split the string with Comma, it gave me problem. Actually total it has 6 columns. But because of internal comma, it gave me 7 columns. And this CSV format can't change so I must deal with this problem. And so here I come out with a solution (because of its too long, I looking for better idea and solutions from you guys ):

I'm trying to import a tab delimited file into a table.The issue is, SOMETIMES, the file will include an awkward record that has two "null values" and causes my program to throw a "unexpected end of file".For example, each record will have 20 fields. But the last record will have only two fields (two null values), and hence, unexpected EOF.
Currently I'm using a StreamReader. I've tried counting the lines and telling bcp to stop reading before the "phantom nulls", but StreamReader gets an incorrect count of lines due to the "phantom nulls".I've tried the following code to get rid of all bogus code (code borrowed off the net). But it just replaces the fields with empty spaces (I'd like the result of no line left behind).
Public Sub RemoveBlankRowsFromCVSFile2(ByVal filepath As String)
If filepath = DBNull.Value.ToString() Or filepath.Length = 0 Then Throw New ArgumentNullException("filepath")
If (File.Exists(filepath) = False) Then Throw New FileNotFoundException("Could not find CSV file.", filepath)

I've tried using SSIS, but it encounters the EOF unexpected error.
I am creating a shell for a FORTRAN application which reads a tab delimited text file.Because I am using Excel to manipulate data, is it possible to use the Excel Automation features to "save as" a tab delimited text file?The only method available seems to be a unicode text format, which does not work. Or is there another format that mimics tab delimited so that the FORTRAN application will read such a file without difficulty?
View 1 RepliesI am trying to import a TAB (NOt comma) delimited text file into a DataGridView. The following code works fine if I have a comma separated file. All I have to do is change the FMT to "Delimited".It just does not work with FMT=TabDelimited. All columns are read into single datatable column. The text file is ANSI text and I have double checked to make sure Tabs are tabs and not spaces, even exported a sample Tab Delimited file from Excel.Can this even be done using Text Driver? [code]

I would like to know a way (of course I want to know the best way) to edit a csv file, preferably without having to read the original and write the results to a new one.
Example 1: I want to split the contents of a column into two columns 123abc into 123, abc
Example 2: I want to remove letters from the beginning of a column AB123 into 123

I've created a program that will allow me to save user input into a text file on my C: drive. I'm trying to figure out a way where the text will be saved using a tab delimiter (I'm still new to Visual Basic.NET 2003). What I have to do is get the information to save in the form of columns and rows so that when the text file is opened using Microsoft Excel (ex. Microsoft Excel 2007), all of the information will be saved in its own columns and rows without any manual intervention (ex. no changing column widths or anything like that).
Here is my code so far.

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub

When opening the text file using Microsoft Excel, Excel should display the data like this:
Name | Mailing Address | Age
John | 2300 J. Street | 19
modify my code (so that the information will be using a tab delimiter) whereas the text can open up in the right rows and columns in Excel after a user has submitted the data to the text file.
I am working with a database that is used for managing program requirements ie text fields of varying lengths. The database program is capable of exporting data out in the form of tab and comma delimited files. I would like to see an example in vb.net 2003 of how I might be able to loop thru an entire delimited text file line by line isolating each tab delimited field to say a text box or a string variable.My ultimate goal is to be able to write this delimited data to a special spreadsheet application capable of dealing with text block sizes beyond the capability of Excel. So now I am interested in how to manipulate huge delimited text files in vb.net 03.
View 4 Repliesthis is how i would normally import a comma delimited text file into a ms access table:

my question is, how can i do something similar for a tab delimited text file?

Currently I am building an application that will do Data Validation on an Excel Spreadsheet.The application will allow a user to load an Excel Spreadsheet in and runs checks on the data. The application needs to export the spreadsheet as a pipe delimited file with all of the fields separated by the character.Currently I have written an Excel Macro that will export it as a Text File then delimit it and save the text file as a .ps1 file. I cant seem to figure out how to write this same code in VB instead of VBA.I am currently using Visual Studio 2010.Here is the code for my Macros that work fine but I need it in the application and not on the spreadsheet.
