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 am trying to load a listbox from a text file, I have debugged the routine and have used the "step into", I have the routine in the Form Load section, it shows the names being loaded but will not show in the listbox itself, please please give me some ideas I have been racking my brain for days on this,

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.
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)

Here's what the file looks like:
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?
I am trying to load the text file to the ListBox Object. But it doesn't work.

I have a rich text box which I use in order the user is able to add pictures, coloured writing, different font etc... however I need to load specific text in the rich text box when the user load the Form.how I can add (I guess) the HTML to load this every time the user load the form.
P.S the text will change depending on who loads the form so I can not do a simple
RichTextBox1.LoadFile("C:Documents and SettingsDesktopSigniture.rtf")
I want a rich text box to display public variables like (pizza toppings links etc that have been selected in other forms) these variables have declare in a module. But I want the rich text box to display these variables as soon as the screen loads ( a on form load event) if you know what I mean.

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?

View 7 RepliesI'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 can't really explain what I'm trying to say but here is an example.
Example:
Created 1 Listbox named Box1
Created 1 Button named Load

I'm trying to create a favorite box in my web browser using this code in Favorites.vb

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.
