Reading A Tab Delimited File?
Jul 19, 2006
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.

So I've been using VS2010 and haven't had too many problems transitioning over but I have an issue at the moment and I can't seem to find the answer...I have been using a little piece of code to insert comma delimited files to a database, which works great.Today, I received a Tab Delimited file from a client....obv I could edit, replace tabs with commas and move on but I want to know the right way to do this so I feel accomplished I've tried two ways so far1. This is the code I use for comma delimited with a slight change for the tabs -- PF refers to a class module that has the functions I use to get files and parse file paths
Dim Conn as New ADODB.RecordSet
PF.InputFile = PF.GetFile("Select LMR Demo File", "")
conn.Execute("SELECT * INTO [tmp_lmr] FROM [Text;Database=" & PF.InitLoc &

I 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 want to read a tab delimited file so i set up a data reader with the following connection string: [Code] However when I do this it doesn't seem to delimiter at the tab characters (I cannot work out why it is breaking up the data where it is). the first few lines of the csv are in the attached "dbamstr.txt" - the select statement I am running is: "SELECT * FROM dbamstr.txt".

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
Function GetFilenameFromPath(ByVal strPath As String) As String

I've started this with this code but not sure how to go about the next stage:
Using MyReader As New _

Is there a set function in vb.net that allows you to read a delimited file with text qualifiers? In the past I have used the split command but that does not allow you to take into account the text qualifiers.

I am trying to open a text delimited database using the jet.OLEDB.4.0 driver. My connection string is as shown here:
Dim sConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=" & dataDir & ";
Extended Properties=""text;FMT=Delimited( )"";"
I have read that you either need to alter the registry, or to add a schema.ini file containing information about the delimiter in order to recognize the delimiter. My question is if there is any way to do this without altering the registry or adding a schema.ini file, as both of these are unfortunately not an option. The only solution I currently see is to split each row, is this the only way out.

I'm busy with an applicaton which reads space delimited log files ranging from 5mb to 1gb+ in size, then stores this information to a MySQL database for later use when printing reports based upon the information contained in the files. The methods I've tried / found work but are very slow.
or is there a better way to handle very large text files?
I've tried using textfieldparser as follows:
Using parser As New TextFieldParser("C:logfiles estfile.txt")
parser.TextFieldType = FieldType.Delimited
parser.CommentTokens = New String() {"#"}

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)
[code]....
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?

I want to load a csv file (A comma delimited text file) into a datatable. I found the OdbcDataAdapter Class which looks perfect, but it says it is supported only in version 1.1 of the .NET Framework.
Is there a better way to import a csv file into a datatable? the first line has the column headers.
I am using Visual Studio 2008, using version 3.5 of the .NET framework

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
Clarification: I do not need help solving my examples; I just need to be pointed in the right direction of reading and editing the same file.Here is a code example of using a temporary file that seems to me is too slow
Dim currentLine as string()
tempFile.AutoFlush = True
Do Until origFile.EndOfData

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

this is how i would normally import a comma delimited text file into a ms access table:
sql.CommandText = "SELECT * INTO [tblMailList] FROM [Text;DATABASE=" & System.IO.Path.GetDirectoryName(Me.OpenFileDialog1.FileName) & ";HDR=NO].[" & Me.OpenFileDialog1.SafeFileName & "]"
sql.ExecuteNonQuery()
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.

I'm trying to parse a text file. First I plan on extrcating each line, then extracting each field by searching for a tasb.When I use InStr to search for a (return for end of line) or (for tab) I always get a zero. But if I put in a visable letter such as a I got a 5.also I tried /r, /n and all return a zero.The file looks as follows:
ID Name
1 Patient
2 Bed
3 PatientSet
