Deleting A Line From Text File Using Edit?
Jun 21, 2010
Ok so i have a uni assignment to delete lines of text out of a text file, so far i have figured out how to search the text file for specific bits of text, i,e name of user, ive also used a loop to find out what line in the text file the specific line exists as...my
code so far is
Dim line As String
Dim Input As StreamReader
[code]....
the selected policy is what im tryin to use to write over the line of texts that already exists however i think that maybe instead of deleteting what exists it will just move it down a line and make a blank line

I know how to search a text file for a specific line, but what I don't know is then how to delete that line?My text file is set up as such:
021,Donovan,56 Eynesford Crescent,Bexley,SE5 1TR,09/08/1967,13 March 2012,Bronze
062,Fredrikson,6 Freil Road,Gravesend,GR9 TRB,12/06/1995,13 March 2012,Silver
So I know how to search for the 3 character integer at the beginning of each line, but how do I then delete this line?
I'm currently using this code
Imports System.IO
Public Class Form6
Private Sub SearchBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SearchBtn.Click

I am busy with a project converting VS2005/2008 sln files.
I am quite far but have came acroos a problem with my source code.
I have found the files I need to change, I have changed them to the version that I need.
I now need to read the files back into my program and delete the line I have changed as it contains project numbers that are irrelevant. Then I need to save it.
I have got as far where I have searched for lines that begin with 'Project'. I have changed this also so it's now a question of reading the files in, Deleting the line with the 'Project' number and saving them.

I am trying to speed up the process of changing flags within an INI file used for a program. Ideally i want a simple form with ON/OFF radio buttons which are specific to different options within the ini file. For example, if i wanted to turn Printing off in the ini file, i could select OFF for which this will edit the ini file and change the setting "Printer=0"
Code:
Dim file As System.IO.File
Dim reader As System.IO.StreamReader
Dim line As String
Private Sub RadioButton1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton1.CheckedChanged

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.

Basically what I'm trying to do is read a text file line by line. After each line is read, it will put each line into a separate text box. I've been trying to do this for a while and so far I haven't been able to. I tried using a for loop, but that just put all my lines in to one textbox.

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.

i've made a playlist system. It writes all the music file url's to a file separated by a comma. But I want to have a delete button that removed one of the playlist items.
This is what I've tried:

EntireFile = myReader.ReadToEnd()

I know that Deleting a specific line in a sequential text file is impossible but instead copy the needed lines and not copying the unneeded ones to an output file .. killing the old one and renaming the new one with the same.. I can't make this step...
That is my record file
Code:
Input #1, CustomerName, CustomerHomeAddress, CustomerBussAddress, CustomerTel1, CustomerMob1, CustomerID, DateRent, CarRegPin
Code:
"Josek Sam","68 West Land Street","149 Union of States","4524563","45635463","JOSKSAM1",#2009-03-02#,"MILANCGLZ2008"
"Josef Malm","142 Unions Street","64 Hamersters Street","452504","42542054","JOSFMALM2",#2009-03-06#,"MILANCGLZ2008"
"Dave Green","131 Oxford Street","96 BlueBane Route","452542452","43254345","DAVGRN3",#2009-03-07#,"MILANCGLZ2008"
I made a form that when you put your CustomerID in Text3 Box.. it access the records and make some calculations. now.. The customer will return the car.. Then his data should be deleted.. I want to know how to make that when I enter the CustomerID and press on the Command button .. It copies the other lines to a new output folder and doesn't copy these ... So it appears to be deleted using this way..

i have to make a program thats a telephone directory. All the information is in different text files. The user has to be able to delete and add people to the directory, i have made it so they can add peple no problem but im having a hard time with the code for deleting them. The questions requires that they only type in the persons name and then they are delted but in the text file they are listed as Fred,123-1234 so when they hit delete the person does not get deleted becuase it is registering there full name as Fred,123-1234 i need it so that it just sees the word Fred and deletes it heres the code. I cant figure out how to do it itried using a query but that didnt work either it just looped infinitely.

I'm currently developing a program which takes inputs on a form, and copies them to Microsoft Word Documents, renames the documents, and saves them in a desired location. Here is an example of the code I'm using to edit the documents[code]...
In general, this works great. It does ALMOST everything I need. Unfortunately, however, it also deletes the bookmarks. This isn't a problem with most of the documents, but on one of the documents being created, I need to leave the bookmarks in place, and just change their text. This is because the program needs to be able to go back, in the future, and retrieve the saved values of these bookmarks.
I tried just eliminating the "range" part of it, and just editing the text of the bookmark itself with a "objdoc.bookmarks("PROJECT_NUMBER").text = xxxx" statement, but this doesn't work.

I have the following code to read a csv file and copy each line to another file as long as it does not contain certain strings, it seems to work a little but it leaves some lines in it shouldn't, and it's also taking lines out it shouldn't as if I keep running it again on each output file it eventually takes everything out!

I am adding line entries in a .ini file. The problem is, I am creating duplicate lines in the file, which I do not want to do. I searched this issue online, and the consensus is to use an array, loop through for duplicates and create a new file. However, being so new at this and teaching myself how to code no less, I am at a dead end. This is not a school project, it is something I am doing for work on my own time. I have all of my code done for the program except for this last step.

I need to be able to search through a text file and find a line of text, then delete that line and the 7 previous lines and also the line following the searched line. Basically the program creates student records to a text file and asks if the user wants to mark the record for deletion then when the user exits the program, I want it to find the records mark for deletion and delete them.The records in the text file look like this:
Name: Some, Students, Name
Age: 20
Phone Number: (555) 555-5555

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.
