Load Text File Into ListBox/ArrayList?

Apr 30, 2010

I would like to know if there is a quicker way to load a text file into a listbox/arraylist than this:

Dim fileList as New ArrayList
Dim fileReader As New System.IO.StreamReader("textfile.txt")
Do While fileReader.Peek() <> -1


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?

Load Part Of An Array Into A Listbox From Txt File

Apr 29, 2012

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.


'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.

Write Listbox Text To Text File And Keep Columns Aligned?

Apr 16, 2011

I've got a program which displays data in a listbox in five columns. All are separated using one or more ControlChars.Tab. I want to write these columns to a text file, however, when I do, my columns lose their alignment. I can change alignment so that it displays nicely in text file, but then it is off in list box. Is there a way to get what I see in my listbox to display the same way in a text file - maybe a different way of separating my columns (not using ControlChars.Tab)?

File I/O And Registry :: Using The SaveFileDialog To Save Listbox Info Into A Text File?

I'm using the SaveFileDialog to save listbox info into a text file. The files save fine, but when you go to save the file, if you hit the cancel button, it will overwrite the previous file you saved, because it's name was the same and it seems to save the previous file as the new name for your next file. Is there any way to catch if the user clicks cancel, and then exiting the sub if they did?

Program To Load The Text File?

Apr 3, 2009

I've been staring at my code for a few hours, and cannot think of the next part.For my final I need to make a hangman program Pretty much I have a button to load a .txt, a label, a multiline textbox(which will be hidden later), and a normal textbox. I need the program to load the txt file, and randomly select a word. Then have the program put a " - " for every letter in that word The program loads the txt file,to the multiline textbox,but I don't know what to put next.

Load Images Using A Text File?

Oct 23, 2009

I have a very urgent project due for Monday and I am trying to implement a very simple Windows Application for viewing files.

One of the requirements is to store the history of images accessed and provide a navigation tool for those images logged into the history.

I have been successful in logging/saving the full system absolute path to a text file. Now it is to be able to navigate through the lines.

I figured I could do this by first counting up the amount of lines in the text file after a new image has been loaded to the display and added to the text file[history] and

Then using the count on the history file of total files to either decrease or increase the number as appropriate to load into the image file the previously written absolute file paths as the new images.

I am writing in Visual Basic using VB 2008 express edition and I can't seem to figure out how to count the lines in the text file and sub sequentially manipulate the line being read to display the image.

Reading Text From A Text File Into A Listbox

Dec 15, 2010

I'm a little new to VB, and I'm in a class for it, but I'm trying to do something we aren't going to learn in the class (mostly out of sheer interest) and I need help. I'm trying to read lines from a text file into a listbox, each line representing a new item on the listbox. For example, if the text file reads: [code]I want to be able to take that as is and read it into a listbox, where those words would appear in the exact same fashion; as a list, each as separate items. I've looked at the Help stuff and learned (sorta) about delimiters... but the thing is I don't want to write my entire list in a continuous line separated by commas--I want it to keep reading each line, and moving on to the next, until there are no more lines left. I am thoroughly stumped, and would appreciate it SO much if someone could help. For a frame of reference, this is the point I'm at now with my code: [code]Note that when I run the program, all it will do is read the first line of text available and stop; once I press ENTER in a text file, it decides to stop reading.
