I am trying to read the code, and pull out the 3rd, 4th and 5th set of each line in to a datagrid.
Dim list = New List(Of datagrid)
Dim FILE_NAME As String = "C: est.txt"
If System.IO.File.Exists(FILE_NAME) = True Then
Dim objReader As New System.IO.StreamReader(FILE_NAME)
Do While objReader.Peek() <> -1
[Code] .....
I get the reg come up ok, but then it errors out with Index was outside the bounds of the array.

I'm trying to read a text file that contains info like this:
ACX-101-011 , J2168
BTXR-130A-013, D6733
AJ4-233-614, T8211
I want to split each line at the comma and write the left side to a textbox and the the right side to another textbox. I'm close, with the code below, but I can only post results from the first line in the file. How do I loop this and append the text results in each of the textboxes.
Dim TempFile As String
TempFile = "temp.txt"
Dim sw As StreamWriter

Ive made a program that reads in data from a txt file that has 4 columns, but it doesnt work if there are headings to the columns or any other kind of text at the top of the file. I basically just want to be able to skip any text at the top of the file, either by the user specifying how many lines to skip, or by code that can calculate how many lines to skip.
At the moment, the code opens the file, calculates how many lines there are in the file, redims an array to this size, closes the file and then reopens it so its ready to have the data read.
This is how the data is input into the array at the moment:
ReDim data(lines, 3)
i = 0
While Not (EOF(1))
[Code]....
I was thinking a possibility would be to use a try statement so that if the data is a string, then it skips over that line, but i couldnt figure out how to put it together.

I am currently trying to write a program that will do the following. 1. The user will open a .txt file that needs to be converted into a CSV file. 2. The user will then click on a button to convert the file. 3. The program will parse the .txt file for the necessary data and will then write the data to a new CSV file. So far I am sure that I can write the code which will open the file and which will save the file to the new format. Where I am having problems is with the .txt file format that I have to work with. [Code]
Each field is fixed length with the empty space in front of the starting numbers being a field. I have been unable to find any code that would show me how to parse only certain data from this .txt file. What I need it to end up looking like is this: [Code] The program itself needs to be pretty simple as the .txt file will only have at most 25 to 30 records. I was thinking of using a StreamReader to read the data into an array, but I can't figure out how to get just the data I need out of each record.

The program that I am writing has three default variables that I would like it to store and also be able to change. I have them in a text file called "settings.txt" The format of the text file is as follows:
Default Source "I:DCIM101MSDCF"
Default Destination "C:Documents and SettingsChristyMy DocumentsMy Pictures"
Default Backup Destination "D:My DocumentsBackupMy Pictures"
The field descriptions eg "Default Source" take up 30 characters, so the variable data starts with character 30. I know their has to be an easy way just to pull out the data from a particular line starting with character 30 but I can't find it.

I'm working on a program for a side business I run with a friend, who is a non-programmer.I've done a program before, using IO.StreamReader and IO.StreamWriter to read and write lines to a text file.
But now, I'm working on reading text data (it's output from an old legacy program) that reads a first and last name, and the customer number (6 digits) from one file.
Then, it uses the data (customer number) read the first time to cross reference the zip code and status from a second file, and display it.
The Data in the Text Files are as follows:[code...]
How would I begin parsing for the first and last name, and the customer number to assign to different variables?In the line that references names.txt I meant to put customers.txt.
That's a snippet of code I took from a previous program, so I know how to read the data, just don't know how to extract it.

Even a primer on just reading/writing to a text file would be golden. The array confuses me further, but understanding the data is primary.
Basically, we're writing a program to manage inventory for a bar. Fields and a few lines are below. The delimiter is "||"
So... How do we read the data into the arrays? NAME would be strName(), etc for all of them.
how to write and update existing data.
UID||BREWERY||NAME||SIZE||FORMAT||SEASONAL||PRICE||CASECOST||CASEQTY||BREWERYLOCATION||BREWSTYLE||ST YLE||ABV||CLASS
A0101.12B||Abita Brewing Company||Abita Amber||12

I am trying to read in demographics from a text file. What I am trying to do is use the commas in the text file as a stop and starting point for each field. Instead of explaining all will be clear once you look at the code.
Dim filecontents As String
Dim newlineindex As Integer
Dim numindex As Integer
Dim credents As String

I have read the contents of a text file that looks like the following lines into vb;
this_date = "1-2-09"
// user input
//user input
this_date = "2-22-2009"
[code]....
(there is no limit to how many "this_date" lines or "//user input lines" there are in the file and additions are made often ) When I read the file in vb I wish to only capture the last "this_date" only as the rest are irrelevant.

I am reading a text file with mostly alpha characters. the content is not really relevant but the size of each line is very important. The process I will feed this text to will require each line be no more than 50 characters. So I will pre-process the text and add line feeds to make sure that happens.I tried several VB.NET regex like ^.*$ but that doesn't really break up the lines by 50 characters. I would take the result and iterate through each match and then cut it up and write it to an object in memory. Can this be done with a single regex pass?Otherwise I will use a streamreader and on each line check the length and if <=50 write it out with a streamwriter. if >50 cut it up in sections of 50 and then use streamwriter.
A brief example of my text:
119 SMITH KATY AAAA F ZZZ X NB SX ET
MILES,200/LM450

I am writing a program that lets someone click on a picture to vote for their favorite pet. The part I am stuck at is: when the application is opened and closed it needs to remember how many votes there were. To do so, when the program is closed I have the information stored in a .txt file. it looks something to the effect of:
name, type, votes
andy, bear, 0
bart, dog, 0
candy, cat, 0
hopsie, bunny, 0

i'm using Regex.Split to convert a text file's string to System.Array. The end result is System.Array of 211 strings.
Now what i need is to convert System.Array to a Byte of 211. How would I accomplish this?
System.Array to Dim x(211) as Byte?? Sample code would be great here. I've already visited many sites on this subject with no luck. code below.

I've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.
(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this
If FirstLineOfTextInFile = "English" Then
EnglishForm.Show()
ElseIf FirstLineOfTextInFile = "Metric" Then[code]....
And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.

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'm a little new to VB, and I'm in a class for it, but I'm trying to do something we aren't going to learn in the class (mostly out of sheer interest) and I need help. I'm trying to read lines from a text file into a listbox, each line representing a new item on the listbox. For example, if the text file reads: [code]I want to be able to take that as is and read it into a listbox, where those words would appear in the exact same fashion; as a list, each as separate items. I've looked at the Help stuff and learned (sorta) about delimiters... but the thing is I don't want to write my entire list in a continuous line separated by commas--I want it to keep reading each line, and moving on to the next, until there are no more lines left. I am thoroughly stumped, and would appreciate it SO much if someone could help. For a frame of reference, this is the point I'm at now with my code: [code]Note that when I run the program, all it will do is read the first line of text available and stop; once I press ENTER in a text file, it decides to stop reading.
