I'm trying to write data to an INI file, I've got some code to read it: url...I've tried to modify this code to get it to be able to write to INI files, but I haven't had much success.I know there are DLL's designed for this, but I would like to have my application so it can be distributed as a single EXE.Also, I know there is My.Settings, but I cannot use this, as this INI file is used by another application, that I have not developed.
So, I was wondering if anyone could help me modify this code to write to an INI file, something like WriteIniValue(IniPath, Section, Item, Value)
Dim fcr As System.IO.FileStream fcr = System.IO.File.Create(Application.StartupPath + "" + sname + ".htm") it creates the file fine. how can I write inside this file though?

I 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. What am I missing here? EDIT - This is just a simple winform that I specify a path to a local HTML file in Textbox1 and I'm attempting to parse some HREF tag data.

I can read the file when I run the program, but how do I write the file path so that someone else can download my program and file and read the file on their system?
I'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") Private Sub btnDisplay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplay.Click

The problem is that this will just overwrite what is already there. I would like to have it append the EHomeLog.log every time it is called.
I am using Visual Studio 2008 on Windows XP SP3. User has Windows 7 Pro (32 bit). The IO code below works for me. The read code works for user, but the write code only works for new files. If the user tries to overwrite a current data file, then no data is written to disk. I have done all the usual IO checking (valid file name, etc.) and have excluded it from my same code. In my app, FileSave and FileSaveAs both call WriteDataFile(FullFileName). Any reasons why FIleSave would work on Windows XP, but not on Windows 7 Pro (32 bit)?
Code: Public Function ReadDataFile(ByVal FullFileName As String) As Integer ' reads a Data file from disk ' ' Format is a text file, with [TAB] seperators and [CR][LF] as line terminators
I have a text file and I want to take the data from the text file and write each line into the excel file (into the same column). How do I accomplish this? I know how to read data from a text file, but I don't know how to insert the data to a excel file..
I have an issue where I need to load a fixed-length file. Process some of the fields, generate a few others, and finally output a new file. The difficult part is that the file is of part numbers and some of the products are superceded by other products (which can also be superceded). What I need to do is follow the superceded trail to get information I need to replace some of the fields in the row I am looking at. So how can I best handle about 200000 lines from a file and the need to move up and down within the given products? I thought about using a collection to hold the data or a dataset, but I just don't think this is the right way.[code]....
I am working on a program with multiple collections related to one another for a school project. Each collection needs to have its own defined properties and have the objects written (1 per line) to a text file.
I have all of that working.
When reading the comma-separated line from the file, I want to place one of the properties of the object in a listbox (so that all the objects' names will show up in the listbox). I think I have this part figured out...
My problem is that when you click on the name in the listbox, I would like multiple text boxes to be populated with the appropriate, corresponding properties of the particular object in the collection...is there a way for this to be done?

What my program does is load a file (password list), then progressively reads each line of text in the file whilst writing each line to a new file. After X amount of lines have been written, it should start writing the lines of text to a new document until the initial password list has been split into X amount of password lists. The problem I have is that after hours of tweaking, all I can get it to do is write either blank ocuments, or write all of the lines to only one file. I really need it to be able to split into multiple files, preferably at runtime rather than loading a whole text document into the program in a textbox or array then writing it to new files.Below is the source:
