I am looking to compare lines within a .csv file. I want to start at the bottom line and compare values within it to those in the line above and then repeat the process, ie. the second bottom line to the third bottom line and so on.The code used to compare straight out variables I can handle, the difficultly for me lies in identifying particular lines and fields within a text file.If someone would be kind enough to provide the code for this, I have googled it but it's clearly beyond my ability.

I'm willing to compare a textfile (whatever) which contains a few lines of text. After the comparison it should download and replace the "changed" folder/file. E.g.
(Local txtFile)
maps: 1.0.0
db1: 1.0.0
db2. 1.0.0
(Server txtFile)
maps: 1.0.1
db1: 1.0.0
db2. 1.0.0

I have written a simple script to get a bunch of lines from a text file (they will be filenames eventually) which are split by new lines and puts each one into an array..
Dim ary() As String
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If My.Computer.FileSystem.FileExists("C:MenuFiles.txt") Then
[code]....
The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.

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 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 a text file that I'm reading into a listbox. I want to skip a line if it's blank. The following code works if I leave out the check for the line being blank. It puts the file in the listbox with no errors. However, when I include the If statement that checks for the line being blank, I get an ArgumentNullException in the Items.Add line when It gets to the end of the file.

Sorry if this seems like I haven't searched, however I have. Maybe I'm not understanding something or maybe I just haven't found what I need. Anyway my question is this. How would I find multiple strings in a text file and replace them? So far I've been able to find out how to replace a single string with:

I am in the process (slow process) if learning vb.net by trying to create a simple application that will read and write (save) chosen information to a text file. The application has text boxes (name, email address, etc) and I want to read information from certain lines in the text and place in the given text box.[code]When I start debugging mode it does not display the text until I click onto the text box and it's displaying the first line of text in the file. How do I skip the first line of text and have it display the second line (or the 6th, 24, or whatever line I need to be displayed)?Then I can start working on learning to use streamwriter

How can I get the sum from richtextbox, starting at line -1 ? But the first line should compare with line1.This code adds a constant to all lines and passes the sum to another textbox.
Dim num1 As Single
Dim sum As Single
Dim Constant As Single = Val(txtLowerTol.Text[code]....
So a third textbox should sum with one line "offset".

First I create a class which have a string property
Property stdName() As String
Then I open a text file and put into array of that class
Dim arrStudent() As Students
Dim allstdinfo As New IO.StreamReader(dlgOpenStudentsFile.FileName)
Do Until (allstdinfo.Peek() = -1)
Dim strAllstdinfo As String = allstdinfo.ReadLine()
Dim arrStudentLine() As String
[Code] .....
Finally I run a for loop and compare the stdName property with textbox.text
Dim counter As Integer = arrStudent.Length
(debug here)
For i As Integer = 0 To counter - 1
If (String.Compare(arrStudent(i).stdName, txtStdName.Text) = 0) Then
lblPhoneNo.Text = arrStudent(i).phoneNo
End If
Next
And I add watch:
Why the compare return 1

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..
