Simple Read/Write App.config Configuration File

Feb 6, 2010

I have a program with various settings, all stored in the app.config file. Often, I have a need to edit the connection string setting. I cannot do so using the My.Settings.myConnectionStringVariable method, as this is read-only. What I would like to do is have a big text box, and simply load the entire app.config file into it. The user could modify whatever they wanted, click save, and the program would save the new edits to the app.config file, and restart the program. I don't have a huge need to only pull out the connection string, as getting the text for the entire config file would suffice. However, if it is easier to pull out just the connection string from the config file, that would work too.

Read/Write To A Text File?

May 6, 2012

I'm writing an application for my Smartphone (OS is WM6 pro .NET Compact framework 3.5). Up till now i used VB6 so i'm pretty new to VB2008.

The application needs to store a set of items in a text file located on the device and retrieve them back. Since WM 6.0 doesn't support MS Access databases i have to work with the old fashion text files to store and retrieve my data. However since i'm new to VB2008 (and given the limitations of writing a smartphone application) I would llike to know how to write and read data to and from a text file.

VS 2008 Use An XmlTextReader To Read Simple XML Data From A File?

Mar 17, 2010

I'm trying to use an XmlTextReader to read simple XML data from a file I wrote using the XmlTextWriter class. I've very little experience with XML and reading/writing from it, so it's been a little struggle. The writing part went OK though, but I can't really figure out how to do the reading. All examples I found using google handled it all slightly differently, and none made it really clear what they were trying to read...I am storing the position, size and a filepath of MDI windows using this format:

<?xml version="1.0"?>
<Form X="208" Y="95" W="424" H="277">C:UsersNickDesktopabc.plm</Form>


obviously I cannot do what I want with this. I need to get the attributes in each element too, and I need to read multiple elements and do something for each element...

Read And Write From One Text File To Two Arrays?

Apr 10, 2010

I've been making a program whereby users names and numbers must be stored in external files. At the moment I can get the names to read and write to a file with these lines:

Imports System.IO
Public Class frmDefaultMenu
Private Sub frmDefaultMenu_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load


Where each line has a name, a seaparator (,) and then the corresponding number.

When the program loads I would like it to be able to access that file, and store all the names into an array named ExistingUsers() and all the Numbers into an array called ExistingNumbers(), and then when a new name is added in the textbox, it is assigned the number "100" and placed at the end of the array, then when the application quits OR straight away, the external files are updated.

VS 2008 - Simple Text -> Xml Program - Save The Contents Of The Bottom Text Window To An Xml File

Dec 23, 2009

I have this Quiz software that lets you create online multiple choice quizzes which are great for studying (I am in grad school and I'm trying to use everything I can to learn). So the Quiz software is great but it only lets you input questions by hand, one by one. I took a look at the .xml file that the quiz program spits out and came up with the idea to try and make a converter so that I can import many questions at once. I was hoping to try and solve this limitation by doing the following:

Take a .doc that say a tutor gives us with a bunch of practice questions, and then take that into Crimson Editor, and then format it so the question is on line 1, the multiple choice answers are on lines 3,4,5, and 6, (for the next question, the question would be on line 11, and the answers on lines 13, 14, 15, and 16, and so on) and then take that saved .txt file into my program, hit the generate button, and it will spit out the .xml file, and then import that into the quiz software to generate the online quiz.

Here is an attached screenshot of my program layout so far:

I figured out how to open a text file by watching simple youtube tutorials, but I don't know how to have it generate the stuff and have it show up in the bottom text box. I know how to do the coding to convert the txt to proper xml code but I don't know how to be able to save the contents of the bottom text window to an xml file.
