Noob - Remove A Line From Text File?

Aug 18, 2010

I know there's ton of examples on the forum but i could not get it to work the way i want.

Sample CSV :-
Unused,172.22.21.2,SD103001
Unused,172.22.21.3,SD103002
Unused,172.22.21.4,SD103003

And what i wana do is change the Unused to Used so basically once this is done it will look like.

Used,172.22.21.2,SD103001
Unused,172.22.21.3,SD103002
Unused,172.22.21.4,SD103003

One thing to mention is i dont want to loop through the whole file and change all the Unused to Used. So basically software fires up opens the file and looks for Unused and changes it to Used and does the rest of the function and shuts down. Next time the software is fired up it goes through and does the same thing.

FCL For A Method That Will Allow To Erase A Line Of Text From A Text File And Replace It With Another Line Of Text

Dec 19, 2008

I've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?

In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:

Dim user_data_file As String = "user_data.txt"
edit_input = New StreamReader(user_data_file)
Dim edit_line As String = edit_input.ReadLine

[CODE]...

However, I can't find any methods that will allow me to do this.

I currently have a bunch of text files I need to edit in a folder, I need to edit each file and remove the same line but not all files have this line, so I need to create a script that needs to check if the line exists then remove it.I have 1000s of files, that's why I need help to be able to create a script that does it for me instead of me editing each one manually.I am not sure on how to do this, but I am sure it is not difficult for people that have good experience with VB.net.

Reading Text File Line By Line, With Resetting Position To Beginning Of File

Jun 23, 2011

I'm reading a text file with StreamReader, line by line. If a condition is met, then I do an operation and then start reading the file again from the first line. I realize I could close and then re-open the file, but surely this would be very slow.

I could do this easily in VB6, but pulling my hair out trying to do this in vB.net. It seems that 'Seek' is the function to use, but it doesn't work.

I've seen other examples, where it works, but you must open it a different way -- with a file number.

Imports System.IO
Dim I as Integer
Dim LineText as String

Remove Character From A Text File And Prevent Crash W/ No Text File?

Apr 7, 2011

All I would like to do is remove one character from the line of the text file that I am reading, which is the first character and also prevent the program from crashing if no text file is present.Here is the code. Can anyone notice where I am going wrong? I thought the "if" statement would cover the crash but it didn't. Clueless, but sort of have an idea on the character removal.

Comparing Text File Records Line By Line?

May 14, 2009

I have to create a new program that reads to Text files. These text files are in the form of a report (with column headings). The purpose is to compare each record line by line to see if their have been any changes made. The record is based on an Account#. Over time these files will be considerably large. What is the best way to do compare records from each file. I'm thinking loading each file into an array and processing them that way.

Search A Text File Line By Line - VB08

Apr 8, 2010

I just joined this forum as I've been looking for a nice and serious VB forum for a long time

I'm having troubles making a program to search a text file line by line for a specific string.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim objReader As New System.IO.StreamReader("C: est.txt")

[Code]...

as you can see in the code its supposed to read a text file and if the line contains the same string as in the textbox then its gonna make a messagebox.

now the problem, if the line does not contain the specific string but the next or any line other line does, then it should automatically read the next line on "Else" and that's where I'm lost

for a "Readnextline" command or something like that?

srFileReader = System.IO.File.OpenText(sFileName)
