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?

I'm trying to figure out how to load a textfile into a listbox. On button click it would pop up a window where you'd browse to the folder and file and then select it and it would populate the listbox.[code]...
View 1 RepliesIt 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'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.
here is my code
Imports System.IO
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As

View 2 RepliesI can retreive all items in my notepad but when I am adding them up in my listbox, and trying to print them in the console. I can only display two strings. I don't know why. My string is a combination of a name, space & score. ex: "luke 300". That is the pattern of all strings per line in my text file. I am separating the name and the score using space as the indicator. When ever a space is found, string before and after the space is retrieved and added to the listbox
Here is my
scorelist = New ArrayList
reader1 = My.Computer.FileSystem.OpenTextFileReader(My.Application.Info.DirectoryPath & "scores.txt")

Now I want that presented in the listbox with the semicolon and it should be aligned per column so that the numbers, the names, the prices and the quantity are exactly aligned per column.If I read the file like this:
[code]...
Then the semicolon is not presented in the listbox and I don't have any alignment per column. As the names of the woods are not equally long the prices and the quantity are not aligned directly below each other...
My questions are:
1) How to add the semicolon in the listbox as seperator of the columns
2) How to align the 4 columns in the listbox (as I have an array Item(3) )
Later on I need to be able to change the quantity (last column) from 0 to > 0 (that's why I have to use an array)
I am trying to create a textfile and write some lines into the textfile. However, the code that i am using can only write when the textfile is already created in the directory.
For this case, can i actually allow my script to search if a textfile is being created, if not create a textfile ???

If I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:
a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).
b) PreferredHeight does not not appear to give the correct integral of item heights.
Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?

just another little problem here! Trying to write a quiz for a college portfolio and having trouble with writing to a .txt textfile. On one form(form4.vb), I have a listbox that picks up the information held within a notepad textfile called "usernames" which contains names of quiz users. When written in manually to this textfile, my listbox picks it up fine, however, on a different form(form3.vb), I have a textbox where a user inputs their name, this is supposed to go to the "usernames.txt" textfile to be picked up by the listbox on the other form but instead, it does not write anything at all and if there is already text on this textfile, it wipes it all out.I also have to use the application.startup path instead of the usual C:my documentents etc so i would have to begin with something like this: (Note: code is a little mixed up due to messing around with different variations but this is just a example)

I have a textfile with timestamps and the amount of minutes my machine has run.
To keep the size of the file in check, I would like to delete the first half of the text file, once the textfile exceeds 1 MB... I have a check in place to determine the file size.
What is the best way to go about deleting the first half of my textfile log?
Do you recommend storing the second half in a temp file, and transfering it to the original log?
Is there a simple way to remove the first few lines of a textfile?
