Extract Specific Data From A Text File?

Feb 16, 2010

Imports System.Globalization
Imports System.IO
Public Class Form1

[Code]....

I have found the above code from the net and it works fine as I would expect. I know this because I have added a put the String StoreFile into a text box and it worked. From what I understand about the code above is that we are reading the file test.txt until we reach the end of the file and we are storing it into a string.

What I would like to do is either:

1. Search the String StoreFile until I find the text of my choice, and then extract the characters around it. See attached txt file.

For example, if I wanted to search for MNAUSD in the attached txt file, I want to grab the values on the line (highlighted in blue) and make them available to my program and ignore everything else.

"MNAUSD",UNITED STATES,US $,M,1.558850,1,1.369850,1.113500,L

I know these files are comma delimited, but I would rather use a regular expressions if possible as I have other files that are not comma delimited, so it would be ideal if I have a regular expressions to handle the search and extract

OR

2. Search the File test.txt LINE BY LINE, until I reach my search text MNAUSD and then extract the same values as above.

VS2008 Load And Parse A Text File And Extract Data Between Points On Any Given Line

Apr 4, 2010

I need to load and parse a text file and extract data between points on any given line. I can load the file, but it's the parsing that's giving me headaches. e.g. "Phoned Jim and arranged for John to attend site" First I need to search for "Phoned" because the line always starts with that, and then I need to extract "Jim and arranged for John"

Reading A Specific Line From A Text File And Displaying It In Individual Text Boxes?

Feb 16, 2010

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.

Go To A Specific Line Of Text File Using .net?

Jun 8, 2011

I am reading a text file line by line using StreamReader.Readline(). After reading a line i have to check whether some fields of the line which is read are present in the rest of the file or not. What i am doing is that after reading a line from the file i am passing the streamreader to check whether there are multiple entries. i am trying to use line.Length() to get the length of line, so using this length i can go back to the line

my code:

Dim pos as Long
sr = File.OpenText(filepath)
While sr.Peek() <> -1

[code]....

my problem is that it is not giving me the expected line or it is skipping some part of the line.how can i return back to my line?

How To Replace Specific Line In Text File

Aug 12, 2009

I was wondering how I would go about replacing a specific line of text with different text, and then later reading a specific line of text (from the same file). The text file has a lot of lines, and basically the layout is like this:
Something1 Data I want to read
Something2 Data I want to read
Something3 Data I want to read
Each line has a specific word, and then after that word is the data I want to use for the form.

Overwrite Specific Line In Text File

Jan 12, 2010

How to read from a line in vb .net, I need to do the following:
change the line in a text file
[Path] = "c: hiscertainpath"
With this line
[Path] = "c: hatother
ewerpath"

These paths will most certainly be different lengths, so I need to either replace what's in the quotes or erase the line completely and enter a new one, but in the same spot, not appended to the end of the document.

Reading A Specific Line In A Text File?

Nov 28, 2011

I have been learning VB for about 3 months now at college and decided to enhance my skills by making my own project at home. My project is basically a game where you have to guess if the next number will be higher or lower than the previous version and you can place bets on it. I have done all of this ok but I wanted to create a high score system so that you could save your score.I can manage to write out to a text file ok so that it looks like this

Highscores
Name
Score

[code]....

etc. But I am not sure on how to read in a specific line. So for example I want lblHighscore1.text to equal line 3 of the text document (as vb counts the first line as 0) So far all I have is this;

Dim objReader As IO.StreamReader = New IO.StreamReader("C:UsersKarlDesktopHighScore.t xt")
lblHighscore1.Text = (objReader.ReadLine)

VS 2010 Read Specific Line Out Of A Text File?

Jun 28, 2010

Okay, so I've been looking on the web for a way to read only ONE line out of a text file. Recently I've gotten by by creating separate text file for each line (such as a text file named, "Username", another named "Password", instead of creating a single text file with both the user name and password.) Now I am faced with having to do this. I want a quick and easy way, VB won't let me do open file as input #1 for some reason. I just need the second line of text out of this text file. What is the quickest and easiest (and painless) way of doing this?
