Read Contents Of Textfile Into Listbox?
May 15, 2009I'm trying to place the contents of a text file (just a list of names) into a list box when the form loads.
My code currently looks like this:
Imports System.IO
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code].....
I can get the names into the list box, but they're all on one line. I thought about using a For...Next loop to read the contents of the text file, but I got into all sorts of trouble; do I need an array with that method? So I've got back to the code I originally had.

Read One Proxy From Textfile Every 5 Times?
Mar 17, 2009I have this class:
Public Class ProxyHelper
Private Shared proxyQueue As New Queue(Of System.Net.WebProxy)()
' Just holds the number of times we've asked for a proxy.
[Code]....
This will ask for one proxy each time my webclient does something five times.
My webclient simply downloads some data and views it from a webpage over and over, and after 5 times you will get banned.
Question: How can I make the above code ask for a proxy from a textfile with one proxy on each line?
I will not have a browse function, the proxies.txt will always be in the app.dir
Read Textfile (in Resources) Into A Textbox?
Mar 17, 2009How would i read a textfile that is in My.Resources and put the whole document in a textbox for the user to see?

I have 25 labels and have label name as followsword1,word2,word3,word4,word5 and so on up to word25.

How To Read From TextFile And Store Data To Modify Later
Sep 2, 2011What I am trying to do may be better for use with SQL Server but I have seen many applications in the past that simply work on text files and I am wanting to try to imitate the same behaviour that those applications follow. I have a list of URL's in a text file. This is simple enough to open and read line by line, but how can I store additional data from the file and query the data?
E.g.
Text File:
link1 - 0
link2 - 0
link3 - 1
link4 - 0
link5 - 1
Then I will read the data with:
Private Sub ButtonX2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonX2.Click
OpenFileDialog1.Filter = "*txt Text Files|*.txt"
If OpenFileDialog1.ShowDialog() = DialogResult.OK Then
Dim AllText As String = My.Computer.FileSystem.ReadAllText(OpenFileDialog1.FileName)
Dim Lines() = Split(AllText, vbCrLf)
[Code] .....
Am I going completely the wrong way about storing the data after importing from a text file?

View 3 RepliesUse Textbox To Edit A Textfile Csv Which Has Been Read Into An Array?
Nov 28, 2010I've got a csv text file "test.txt" in the following format with one record per line in the following format: Builder,Bob,B,99HappyStreet,Springtime,4
I've read them into an array and in design use the first two to populate a listbox and then use a selected index to fill text boxes and some list boxes.
ex. TextBox_FirstName.Text = Employees(ListBoxMain.SelectedIndex).FirstName
How do I write the changes made in the text fields back to the position in the file where it was? It has me stumped although I'm sure there is a SelectedIndex option that can work.
I've considered having all the new/changed data saved as a new record and then just deleting the 'old' entry but my delete code gives me a selectedindex-1 index out of range exception error that I'm working on as well. I am sure both problems are related.[cod]e...
