Reading Delimited Files With Text Qualifiers

May 17, 2012

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.

Reading And Parsing Large Delimited Text Files?

Nov 23, 2011

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() {"#"}

Reading Space Delimited Text Database

Jan 16, 2012

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.

Importing And Summing Excel (xls) Or Delimited Text Files?

Mar 18, 2011

how to best go about this project. I have just been given the task of creating a program that will primarily be used to import and sum a excel or text file that is tab delimited. As a quick example the file would be in the following format:[URL]The problem is that I would need to store this information locally (unless you know better) because I need to be able to append information to this from a second (or third, fourth, etc...) file and re-sum it, lets say that this is the second excel file that I needed to sum:

[URL]

I would have to append the week5 and week6 columns and add the Neapolitan row to my summation. This program will then format the sums into a list of the different flavors and the sums of all products sold during the total weeks and output to a text file.I have informed my employer that it would be easiest to do this with a VB script in excel, however, they are adamant that they want this done in VB.NET with a GUI.

VS 2005 Importing Delimited Text Files To Excel With .NET

Nov 11, 2009

I need to dump a bunch of delimited data to Excel. In VB6 days, I would save the data to a text file, then use ExcelApp.ActiveSheet.QueryTables.Add (blah blah blah...) to import the data to Excel (I got this code from recording a macro while manually importing a text file).In VB.NET (2005), QueryTables does not appear to be an option for ActiveSheet.I could take the long path and manually parse thru the data writing to individual cells - however if I could just import it, it would be much faster.Part of the issue is not being able to record a macro in Excel in .NET format.So my primary question is, how do I import a delimited text file in to Excel without having to manually parse the data into individual cells.Secondary question is any tips for not being able to have ready made examples (in VB .NET format) by recording a macro.

File I/O And Registry :: Reading TAB Delimited File Using MS Text Driver

Jun 14, 2011

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]

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.

Reading Tab Delimited File In To Access?

Nov 17, 2011

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 &

My problem is I have very large text files (approx 2GBs+).They have records in them based in one per line.Each line is not the same length and the data can be different lengths all the time.I am currently reading the file line by line, then splitting the data by common characters in the records. To process the full file it currently takes 3hours. This is way too slow for its purpose.

File I/O And Registry :: Reading Text From Non-.txt Files

My hangup thus far is that I can't figure out how to read the data from the .dat files since they are not .txt files. Can anyone point me in the right direction?
