I am trying to delete the last line of a text file, then append new text to the end - The problem I have is that the code I have is set up to search for an Index, not a String, or the EOF line - I tried to modify it to search for the end string in the file, but that didn't work, either - Here's what I have:
'Delete last line
Dim lines As New List(Of String)(IO.File.ReadAllLines(LocalAppData & "settings.txt"))
'Remove the line to delete, e.g.

I have a project where you type something then it looks through a text file for what you typed. I would then like to make a way to edit the text file once I find what I'm looking for. So, how do you delete text from a .txt file that you are searching through? Also, how do you re-write in that place you just deleted the text from?

I am working on a program with a list box that displays text from a selected text file. I have already made it to delete the item from the listbox but I don't know how to get it to delete that same line from the text file so it doesn't just display it again when you reopen the dialog. Any help? I am using streamwriter and streamreader.

I have a routine that will check a text file for a line to be deleted and deletes it when found. Now the problem i have found is that the lines can be slightly different depending on what the user has done. Now in the TXTSETUP.SIF which is a file in the Windows Source you have the following lines FIG 1. FIG 1: It may look like this: ascent.jpg = 1,,,,,,,,3,3autumn.jpg = 1,,,,,,,,3,3

I have JPG images with data stored at the end of them. My goal is to simply remove this data from the end of the file. The extra data is in plain text. The JPG images can still be viewed as normal with this data in them.The plain text in the end of the file starts with the beginning mark of"--------data---------", a line break, and then the data. Then there isthe end mark of the string

I've seen posts on deleting the lines from a text file that are specified as a function parameter, but I only need to delete the first and last lines from the file.
I'm still a newbie when it comes to working in files, but it seems that it should be simple to delete the first line... Just delete all text from BOF to the first CrLf character. Am I right?
As for the last line, I understand that I'll have to get a count of the lines in the text file to find it (as the file won't always be x amount of lines long).

The current code works fine on the very first fresh but after that it doesn't remember what node was clicked. For this refresh I am looking for a ini file and if found I delete the ini file and refresh the tree. The tree has only 2 parents and never anymore then that.
This first part is the timer sub
Private Sub Timer2_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer2.Tick
Dim SelectNode As String = Me.tvFolders.SelectedNode.Name
Try
' check to see if file exist, if so do refresh then delete file
If (File.Exists(appPath & "refresh.ini")) Then
File.Delete(appPath & "refresh.ini")
[Code] .....
Now the main problem is if you click on a child in parent2 and hit refresh it is not sending Parent2 as a treenode to the search function and it doesn't remember the node clicked. But if you click on a child in parent1 it remembers the node but always refreshes to the top parent1 node. but the very first time you refresh in parent1 it works perfect. Even on the second refresh regardless of which parent you are in it never comes back with failed message from the search function.

I have a text file containing lines of data (File 1). I need to delete all the lines in another text file (File 2), which are found in file 1.So I could read file 2 line by line. And then once the line has been read, read file 1 line by line to search for a match. But that's going to be painfully slow.Or I could read file 2 into memory. And then read file 1 line by line and REPLACE the lines in file 2 with nothing, therefore deleting them. File 2 could be 100 mb, so I'm not sure about reading it all into memory.

I'm trying to delete a number of records in a table from the last and forward. My idea is to use sql like this: delete top " & variable & " * from table where ID = something It gives me a general sytax error. Is it at all possible? Fuga. Edit: I also have the order by statement there. I just forgot to put it in the question.

I first want my program to get the text from a text file(I know how that's done), but once it gets it, I want to somehow save it that it won't need to get the text again(for example, if you restart the application, it won't need to get the text from the file because the text is already saved).

I have two text files, the first text file has two columns separated by a space (" ") and the second text file only has one column.
The column 1 in text file 1 and text file 2 match albeit in different order, what I'm trying to achieve is for every field in column 1 text file 2 I want to search for column 1 in text file 1 and display the matching column 2 field in column 2 text file 2.
Dim*OpenTextFile*As*String*= IO.Path.Combine("C:Test1.txt")
Dim*OpenTextFile2*As*String*= IO.Path.Combine("C:Test2.txt")
