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?

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'm having trouble loading images in a listbox. Is this possible? I don't want the listview. I only need the images, not the images as icons for something else. Also these are image from urls.

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've got a problem, I'm making a program that gives you the choice to add items to a listbox, these items are text. When the form loads, i need it to load text from a file into a listbox. For every line I need it to add that text to the listbox. My problem is when it loads, there's an extra line, but that's only after I close the form and open it again. The reason it happens when the form unloads is because the listbox items are saved on form unload. Now, I believe the problem is my code to save the items:
Dim Env As String = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)
For Each item In Form1.TP1.Items
Dim Save As New SaveFileDialog()
[code].....

I'm creating an open-source web browser in VB.NET Express 2008 and I've created a User Setting named History to save a collection of strings for the browsing history. However, when I try to load the history form at runtime, only the first item (of the three I added) shows up in the listbox. Below are both examples of code I have tried to use to accomplish this task.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ListBox1.DataSource = My.Settings.History

I'm trying to create a favorite box in my web browser using this code in Favorites.vb
Public Class favorites
Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
[Code]....
Now I have it so when you click the add button it will put the URL in the string FavList, and place the URL in Listbox1 however I have no idea how to save it, and load it.
So the next time the user opens it, it will have the URL in the string and URL box, so when they click the URL in listbox1 it will redirect the WebBrowser. I think it works like that already I just need to know how to save it, and load it.

I have a program with two forms, one that handles the applications controls, and the other with the functions that open a file (csv), open a database, and query the database. The controls on the first form are a list box, three labels (to display parsed csv information), and three buttons (clear database, load database from csv, and load listbox).
The clear database and load database buttons (events) seem to function correctly.On the other hand, the load list box event doesn't function 100% the way I'd want. [And, I can't test the selected index event yet]
The code for the load list box event is:
Code:
Dim db As New DBUpdt 'second form
b.openConnection("weather.mdb") 'open database connection
db.query("SELECT * FROM stations") 'query database
Do While db.moreRecords

this is the code i have on form load: textbox1.text ="C:Documents and SettingsOwnerDesktop"
here's the code to load the listbox:
ListBox1.Items.Clear()
Dim filepath As String = (textbox1.text)
My.Application.DoEvents()
Try
For Each file As String In My.Computer.FileSystem.GetFiles _
[Code]...
now what this does is load the files w/out the file path or extensions , but, it loads the files in the subfolders as well . i just need the desktop files to load in the listbox, not the subfolder files

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.

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?
