Read Contents Of Textfile Into Listbox?
May 15, 2009
I'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.

I have a form with 2 listboxes. I've added items in each listbox. I save all the items from each listbox to a text file. What I want to do is open the text file and I want each string inside the text file to go to the appropriate listbox. How can I make my program recognize where each string belongs?

Is there a way to write the content of the clipboard to a file on the PC. I'm currently using window7 and i got a tool horst.exe that seems to do something like this. But the tool always crashes on windwos7. So Any program which can be called from shell that writes the content of the clipboard to a file.

I am starting to learn reading and writing to textfiles. One quick problem. My code here
'Read is the variable that will read the kp.txt file"
Dim read As IO.StreamReader
read = IO.File.OpenText("C:2/kp.txt"[code].....
however when it is read into the listbox those 3 words appear on one line in listbox
How can i make it so that each line of the textfile is placed in each line on the listbox?

It may seem noobish but, I've been try forever! I've been postponing a database project for like 3 years and I finally come to some solutions except for when it deletes an Item from the list. On form load, the listbox generates data from a text file (we'll call text1) which has data in it. For every line of data in that text file (text1), there is a text file (text2) in a 2nd folder.
For example, there may be, in text1, a line named "Hi". In the 2nd folder there is a text file named "hi.txt" Another line (say the next line under 'Hi') is written as "Hello world", there will be a file in the second folder called hello world.txt"
May seem confusing but it works well. My problem is making that 1st text file that has ALL of the data that loads into the listbox, be rewritten over with the new data in the listbox OR remove a certain line of from the text file.

I have my code it is able to read a text file and do checks each line if there are 7W and 5L in that particular line, if no matches it will remove that line... 1 problem i face now is that, there are duplicates in my textfile..Im not sure how am i going to remove the duplicate in the text file. I want to know if there is a way to integrate an additional function inside my code to check if that particular line is a duplicate so i can accomplish 2 tasks at 1 time... Since there are about close to 1million records in my text file.

I 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

How would i read a textfile that is in My.Resources and put the whole document in a textbox for the user to see?
I figured i would need a IO.StreamReader and a IO.StringReader but cant figure out too much what to do with these.
I figured i could create a loop until it has read to the end of the document but there is no check called HasLineAvailable or something.

I have a txt document here that have certain word on it per line. How can I show it in different labels. I have 25 labels and have label name as followsword1,word2,word3,word4,word5 and so on up to word25. I want the word 1 label will show the first line of the text file and the second word2(label name) will show the second line of the textfile and so on up to the 25th line . Can it be done using loop?I tried but I dont know exactly how readline process works to identify certain lines you want to read and also I tried using the "i" variable to auto generate the name of my label but it did not work.
Dim timepath As String = "C:ACCOUNTSAccount" + user1 + " ime.text"
Dim times As String
Dim timeread As New System.IO.StreamReader(timepath)

What 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?

I have a textfile I need to open and I need to put each line into the array. What is the simplest way to add the elements/each line's data into the array while increasing the array as it reads each line? This is blowing my mind right now..I thought about using a counter and then redim-ing the array (while preserving of course).

This is my first time using a list vs an array but I'm having a bit of trouble. I am trying to read a textfile into a list of song objects. I am reading the file successfully into the list however after the loop ends the program stops executing the load event and ignores the populateListBox() procedure. Any thoughts.

I'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...
