i'm trying to load a sequential text file into a listbox, and for some reason it won't move onto the next line? instead i get square characters instead
It appears like:
Where the square characters are, i want it to be an extra line as opposed to just that? here's the
Dim YOUREFILE As String = "C:Documents and SettingsAdministratorMy DocumentsPROJECTFILESYOURSTUDENTSCORES.TXT"
Dim objReader As New System.IO.StreamReader(YOUREFILE)
[CODE]...
Here's what the file looks like:

In my program i have a listbox populated with data from a sequential text file. [code] Mary, Murphy, 16, 893782, Douglas etc.From here the user selects the person they wish to see displayed in the datagrid with all all other relevant details from the text file displaying. Problem is I cannot figure out how to refer to the selected person and then get it displaying on its own in the datagrid. [code]

I am stuck on an easy problem I'm sure, but for the life of me i cannot figure it out. I need to read a sequential file into a listbox. I can read the file into the textbox but i want to format the data in the listbox. for example i want to PadLeft(10), delete the excess commas, and give a heading for each column. here is the code i have and attached is the text file.
Imports System.IO
Public Class Form1
Private Sub exitButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles exitButton.Click

I would like to know if there is a quicker way to load a text file into a listbox/arraylist than this:
Code:
Dim fileList as New ArrayList
Dim fileReader As New System.IO.StreamReader("textfile.txt")
Do While fileReader.Peek() <> -1
[Code].....
If I need to load several text files into different arraylists, especially if the textfiles have a lot of lines, this process is very slow. Too slow for my current app to work smoothly, actually.
So, is there any faster ways to load a text file into an arraylist? Or if there isn't, is there some quick way to easily access and change data that is on a particular line in a textbox, so that I don't have to load the text file into an arraylist?

Private Sub frmSelection_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim Datafile() As String = IO.File.ReadAllLines("Datafile.txt")

I am trying to create a program for a voters poll, where when a caller calls in, I can enter their vote for one of the four choices in the listbox and it will be automatically added to the vote count. I got that much to work, I need to save the vote to a sequential text file, when a vote is saved. I know I am close but it is just not quite working. I only need help getting the info to save to the sequential text file. I have also included a jpeg of what the form looks like.

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..

What I am trying to do is connect a sequential text file up to a list view. It displays alright but i have a button which is to add certain details to the sequential text file, but instead of adding it in comma separated variable format, i.e. John,Murphy, etc... horizontally it adds the information vertically downwards, i.e. John

i want to load a text file to my listbox. Chosen using a openfiledialog, so it wont have to be on a fixed location. However, i dont know how to do this. I know how to save a text file from a listbox, but not how to load one into it.
Next question, When loaded into the listbox, how can you select the next line?

I have built a system for a shipping company to use that takes user input from various sources (Textboxes, RadioButtons etc) and displays it in listboxes below. What I need to do is create individual shipping numbers for each of the consignments added based on certain criteria, that being:When adding a consignment, the system should generate the consignment number automatically in the format XY12-xAB, where x is a number that increases by 1 for each consignment, AB is the Shipment Type (EA, SA or SF) and XY12 is the Office ID.
So far, I have this:
Private Sub GenerateConsignnmentNumber()
Dim sConsignmentNumber As String

Where, ";" is the Delimiter and data is just one line only. "A" has to load in TextBox and "Cat,.....,Bird" has to load in ListBox, one line per animal.I've already read the text file and load "A" into text box. But couldn't figure out how to load rest of the data into list box.

in my program i am trying to make it so that when you press a button it opens a "choose file" popup(where the user can choose a text file) then after the user chooses it the program will automatically load each line of the textfile into a listbox.But i have been researching it and the only thing i have been able to find is a file>open thing. So how cold i make it open a "open" dialogue on the press of a button and since i haven't been able to find anything on the open dialogue i haven't looked for anything on the loading each line of it into a listbox?

How do I get my info from a .txt from my website to load into my listbox?! Like if I were to do this...
Try
Dim client As New Net.WebClient
client.Credentials = New Net.NetworkCredential("username", "password")
ListBox1.Items.Add(client.DownloadString("ftp:public_html/listboxitems.txt"))
Catch ex As Exception
MsgBox("Error : " + ErrorToString(), MsgBoxStyle.Critical)
End Try
It just adds a straight line of my multi lines that are in the .txt file...

I am working on an assignment where I need to have a product list that is loaded into a list box upon the form loading. This is generated from a txt file in the /debug folder upon loading. Now my question is how do I have the product names show up in the list box when there are 3 separate parts to each product. The product, the cost, and the quantity in inventory, and all I want to show up is the product in the listbox, where the rest show up elsewhere.
CODE:
'This procedure loads the data for the array from txt file. As well as loading the Product.txt file into the system when the program loads.

My teacher as asked me to allow a user to input three pieces of information about a DVD (the ID, the title and the running time) and for the program to add that data to a sequential file. My textbook fails to explain it and I am at a loss as to where my book from last semester is located at the moment.
1. What is a sequential file?
2. How do I display information from it into a messge box?

Before I begin I would like to mention that I am not a noob in VB, it's just I've never had to do anything this complex before. Basically what I want is to have a program that you can load a txt file in, have it copy key words, and paste it in a textbox so I can use it later on. So in this text file, there is a bunch of info, but I am only needing a certain part. Here is an example of a text file (actually a .dat file, but is easily read):

I am working on a program in Visual Basic that incorporates using a sequential access file for a ballot type program. Each type the user clicks the save vote button, the amount of votes gets stored.
What I am trying to do is in my access file is to display the number of votes as an actual number. The way my program is written right now, the name of the candidate appears as many times as the vote was saved.
for example, if perez was voted for 4 times, in the access file perez is displayed on 4 different lines. How do I display the actual number of how many time they were voted for. I'm thinking using a counter variable, but not really sure how to really implement it in. this is what i have so far.
