Jun 8, 2010I need to write data from a list box to an lsv text file. I can do that if I rea an entire line at a time and write it out, but the data in the listbox are columnated.For example:Cey,Ron 50 75 75 66.67would be an entire line from the listbox. It was entered into the listbox by reading an lsv text file and using format string to set up column info, but I don't know how to read it back out by column, only by entire line.

Sep 3, 2010I am encountering a problem when trying to write data to a text file. If I put the output into a messagebox I can see it, but when I attempt to write it to a file it is just blank.

Changing Data In Text File Or Array?
Dec 15, 2009I have a csv text file, shown below that I want to edit based on user inputs. When the user wants to change the current price of a stock, they enter the stock name, and the new price. When the button is clicked, VB needs to find the appropriate stock, and then change the current price.The data needs to be pulled from the text file into a temporary file, changed, then the temp file needs to be renamed to the original file name and the original file deleted.This is the only part of the program I can not figure out. I have put my program code here as well. The click event that I need this to work on is: Private Sub btnUpdateStock_Click --- I have been playing with code in that section, so that's why there si abunch of crazey code there.

Pull Data Out Of Text File Into MultiDimensional Array?
Jun 10, 2011I have been searching and searching and cannot find out how to do what I'm looking to do, that is the only reason I would post a new thread.[code]...
After reading the file, I want to load the NameId, the ColourId and the Text into a multidimensional array. Anything I have found about loading into an array shows text being separated by small delimiters like commas, but this I cannot do because I need to use this format. What I am wanting to do is load all of the NameId's into a listbox and when a certain NameId is selected, it will bring up the Text in a TextBox and the Colour value in a ComboBox.

Counting Columns In ASCII Text File To Enter Data Into An Array
Nov 21, 2009I am using visual basic 2008 and trying to create an application to plot data from text files. I have several data files of various sizes. They have an unknown number of rows and either 2 or 4 columns.I need to put the data into 2 dimensional array, so value(,) becomes either value(lines,3) or value(lines,1) depending on the number of columns.My program needs to be able to count how many columns there are, and redim value(,) appropriately.I have written a piece of code to count the number of lines (rows) in the file using 'While not (EOF(1)) ....' but I'm stuck on how to count the number of columns.I could ask the user to indicate how many columns there are before the file is read, but I would prefer the program to detect the number automatically.
View 1 RepliesVB 2010 Array/write Array To File?
Dec 3, 2011I'm close to getting this to work, but currently can't get any output to display in the listbox. I had it working, but needed to move some things around to get the join function to work.In my program, a user enters input into a textbox and an array is displayed in a listbox based on what they type in. For example, if they type in "a", all foods (in the textfile that is connected to the program) that start with "a" will be displayed.
When there is output, I need to find a way to name this array (which is created based on what the user inputs) and join all of the items in the listbox (example: foods stacked on top of each other in the listbox will be shown at the bottom as a string).I am posting the code that I have thus far; all of the errors that I'm getting (and potentially my logic errors) are just in the first public class until the end of the first if-next statement:
Public Class frmFoods
Dim foods() As String = IO.File.ReadAllLines("foods.txt")
