File I/O And Registry :: Load - Read - Locate & Copy Text In A File?
Aug 12, 2010Before 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):

.net - Load From File Into Listbox?
Jun 8, 2011in 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?

Load Part Of An Array Into A Listbox From Txt File
Apr 29, 2012I 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.

Load Text File Into ListBox/ArrayList?
Apr 30, 2010I 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?

VS 2010 - Load, Read, Locate, & Copy Text In A File?

What I'd like to do is something like this
If MyProcess.ExceededTimeout Then

Read Info From Text File And Add To ListBox
Jul 23, 2010I am making a program, obviously, and I require some assistance. I found an explanation on how to read information from a Text file and have modified it for my needs. Here is my (modded) version:

Dim ReadInfo As System.IO.StreamReader = System.IO.File.OpenText(My.Settings.OpenPlaylistName)

I pretty much understood how to write text to a file, but I cannot grasp how to READ the information. After I read the information, I would like to add each seperate line to a ListBox. Each line in the text file is a file path for a music file, as the file I wish to read information from is a "custom extension" playlist file. I know what to do after I get the file path, but I do not know how to get the file path from the playlist.

VS 2008 Class And Read A Line From A File And Add It Into A Listbox
Sep 12, 2009I am trying to read a line from a file and add it into a listbox. The SelectedIndexChanged event of the listbox places the selected item (hence, the item I added from the file) into a variable that is declared as a Store (my own personal class.) I can easily add the line from the file into the listbox, but I run into a problem with the SelectedIndexChanged event. When I click on the item in the listbox, I get an error that says "Unable to cast object of type 'System.String' to type 'WindowsApplication1.Store'." (I guess this is because I added an item to the listbox that is from a file.) I tried a variety of methods of casting, but nothing seems to work. What can I do to fix this?
