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?

Jun 22, 2010

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.

Read Lines From Text File 1 And Delete Those Lines From Text File 2?

Sep 15, 2009

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.

Jump Through A File And Read Lines?

Jul 28, 2009

I want to use a FileStream and seek from the beginning of the file while moving forward in the file .01% of the file size at a time.

So I want to seek to a position in the file, read the entire line, if it matches my criteria I am done. If not, I seek ahead another .01.

C# is OK but VB.NET preferred.

I used to do it something like this in VB6...

FileOpen(1, CurrentFullPath, OpenMode.Input, OpenAccess.Read, OpenShare.Shared)
Dim FileLength As Long = LOF(1)
For x As Single = 0.99 To 0 Step -0.01

Read Certain Lines From Text File

Mar 24, 2011

I have this code now doing and that is creating my chart from data off a text file. The final task I need to be able to do, to complete my program is have a way to select how many days of data to populate my chats with via a Text Box input. I am thinking I will need to read the complete text file first to count how many lines are in it, then what ever is put in the text box it will take that many lines of data from the text file and populate the chart. For this to work correctly it would have to read the lines of the file back wards.(last line of file would be the first line..) e.g. textbox1.text = "7" then the chart would show only the last 7 lines of my data.

I was looking up examples of Counting the lines in the file, I think I am close here...
Dim fso As New FileSystemObject
Dim txt As TextStream
Set txt = fso.OpenTextFile(ReadChart, ForReading)
txt.ReadAll
Textbox2.text & txt.Line & " line(s)."

Read Single Lines From .txt File

Mar 4, 2012

I am using vb 2010 and a windows form in my Web Browser project. In my favorites bar I need to be able to import my users favorites (that he may add) through a .txt file. I realize one way of doing this is creating multiple files stored in one master folder and reading the whole file of each which would contain the URL, but I would much rather have them all in one .txt file, but for that to happen i must read line by line from that file to import the favorites. Therefore, my question is how can I code my project to read through a .txt file line by line and return each line in possibly an array? "We are what we repeatedly do. Excellence, therefore, is not an act but a habit."

VS 2010 - How To Read Lines From File

May 4, 2011

I need to read lines from file. Now my code is like this:
Sub data()
Dim reader As New IO.StreamReader("log.txt")
For i = 0 To 1500
date(i) = reader.ReadLine
Next i
End Sub

Now if some user will change add or remove the data from this file, it will end up with error or sth. I also tried to write sth like this:
Open "C:in.txt" For Input As intInFile

But there appears an error, that open is not declared and IO functionality is microsoft.visualbasic namespace. I added this name space (at the top: Imports Microsoft.VisualBasic), but this error still occurs.
