Environment: .Net 3.5 VB.net (C#ok too) I wrote a multi-project WinForms app that needs to load a couple dozen variables from a client section of a config file based on user's selection of client. Also some program variables need to be loaded as well. So far so good, I put them in an app.config file.In the appsettings section I put the main program variables. e.g.
[Code]....
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.

My application is a service application, and it needs to load a set of configuration that the user can change. I was using the System.Configuration classes to set up the app.config file, and then I was going to give the user the option of editing this file to change configuration.
Can I move this file to a custom directory, something like C:settingsapp.config? Or is it forced to reside in the app directory?
I have an application that has a load of values in its app.exe.config file. The application is used by a few users, and the settings would change on a regular basis. so im having to change the config file, and send it out to all users.
I'd love to move the config file to the network somewhere and point the app to this file. ive tried to use;
Imports System.Configuration.ConfigurationManager
OpenExeConfiguration("I:app configHelpDeskQuickCallLogger.exe.config")
But i cant get it to read in the values.
I want to write the connection string of my application in app.config file. I dont know how to write it or how to dynamically change it from my application source code either. My App.config file shows like..
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.diagnostics>

I am trying to build custom configuration section in my app.config file. I am using the following as my example: [URL]. According to this article, I am supposed to inherit from the ConfigurationSection class, add the desired section to my app.config file, and then specify a "configSections" declaration in the app.config file to identify the section and the class that should process it. My problem is that I cannot get the class loader to load my class for processing the section.
If I follow the example and set up my "configSections" as:
<configSections>
<section name="MyStuff.Configuration"
type="MyStuff.MyConfigurer"
allowLocation="true"
allowDefinition="Everywhere" />
</configSections>
I get the following error:
Could not load type 'MyStuff.MyConfigurer' from assembly 'System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.
I think the error is telling me it can't load my class from the System.Configuration DLL and that makes sense; the class is in my application code. So how do I tell it to look in my application code to find the class? Do I have to put my class in its own DLL to get this to work? As an alternative approach, is there some way I can just find the section in the application configuration and process the XML myself? The app.config file is the ideal location for this information. Also, this would be easier for me than going through all of these contortions to do what should be a relatively easy operation.
I would like to be able to read the entire document, and make changes to it before run time. I am making a deployment tool for my application, and most of my customers do not want to rename their servers, nor do I want to have to rename the server in the connection string section of the app config file.

View 3 RepliesI am building the 'TheBeerHouse' project in vb.net (the book is written in C#). Once I understand the concepts, I can usually convert it to vb. However, there are a few areas that give my some problems (which I will address individually). The first issue I have is the C# 'base' to VB 'MyBase'. [code] My understanding of this conversion is that I need to grab the attributes of the <articles> element under the <theBeerHouse> custom section in the web.config file.This code does not compile and the get the following error: 'MyBase' must be followed by '.' and an identifier.

What's the correct code to get a setting out of the web.config file in an ASP.NET application?
NOTE: Although you can add keys individually to the <appsettings> tag, I'm trying to figure out how to use it with the "Settings" tab in the project's properties.
Is there a simple way to read from the global application.exe.config file from a dll?urrently I am loading the file as an XmlDocument but I wonder if there is a better solution.That's what I mean:If I create a new WinForms Project I have a Settings Tab in the Project properties where I can add some simple values (And I want to access the per Application settings, not the user beased ones).From my code I can access these values with:
Console.WriteLine(Properties.Settings.Default.SomeValue);
The Settings class is autogenerated in the file Settings.Designer.cs.Now I have the case where a dll need's to read the settings from the Main Application's config file. Is there a simple way to achive this? Currently I am reading the file as an XML Document.
Basically i have a .net application that has a directory path stored in the app.config file. this directory path outputs xml files that will be read by an asp.net web page.
Is there any way i can get the asp.net web page to read the directory path stored in the app.config file? Should i look to use the web.config file at all?
I am using VB.NET 2010 with a solution that consists of class libraries and winform projects.
Each project has an app.config for it's specific needs. There are however, several settings that are common across all projects. I would like to implement a common config file to hold those, but that effort hasn't been very successful.
After much searching I developed a test program to play with and it was working until I moved the Globalsettings into a separate file. Below is a paste of my code along with the config files I've been experimenting with. I've added the references to system.configuration and made sure my config files are set to always copy to the output directory.
The code compiles, but GlobalSettingsLookup is never set to an instance of NamevalueCollection. I'm guessing it's because the ConfigurationManager can't load the section "GlobalSettings"(?) That's just a guess
My Code:
Dim GlobalsettingsLookup As NameValueCollection = CType(System.Configuration.ConfigurationManager.GetSection("GlobalSettings"), System.Collections.Specialized.NameValueCollection)

How can i read my connectionstrings value which i stored in my app.config file (for windows application)?
i tried many times to use more than one option but i could not do it.
i am using VB.NET 2005 with framwork 2.
Added for my quick reference.When you use the following code to retrieve the values from config file in a library project.
Value = Configuration.ConfigurationManager.AppSettings("KeyName")
The application will look for this key in AppSettings section of calling assembly and may lead to unpredictable results.

Dear Friends: I have some files in 1 folder directory that show "XML Configuration File" under type. But none of these files show the extension .config. The directory filesare like C0150,C0150_new,C0200,C0200_new etc. I need to change only 1 attribute of each of these files. I need to write a VS.Net project to do this. I have to send the .exe file(from bin directory of this VS.Net project) to my client and they will just double click the .exe file and it will change that attribute in all the .config files.
The C0150 file looks like this:
<?xml version="1.0" encoding="utf-8"?>

What is the best way to write data from a hierarchical set of objects to a file? The highest order parent has 1000's of children all with children (DOM style). Trying to traverse the tree and creating one big string which is then written to a file is throwing an out-of-memory exception while creating the string.
Details I've created a set of classes that make up an HTML document. There was control that I needed that the pre-packaged HtmlElement and HtmlDocument didn't give. The Document Object Model is maintained throughout, with some similar methods and properties and such. I'm using the custom classes to create a very large HTML document. When I say large, I mean on the order of over 2000 printed pages. It's doubtful that they will all be printed, but some will be.
My base HTMLElement object, from which all other objects are derived, contains an OuterHTML property which, as expected, gets the full HTML of the calling object and the HTML of all child elements. After the code which generates the report runs, I have my HTMLDocument object containing the entire report which needs to be written to a file. Here is where I keep running into problems.
If I call OuterHTML on the HTMLDocument object, I get an out of memory exception.
Other reports have saved fine, but this is by far the largest report I've thrown at my HTMLElement object. My assumption is that the property call is generating too much text.
I am basically just creating a new .HTML file, opening it for reading, and writing in all of the text. Like:
File.WriteAllText(FileName, HtmlDoc.OuterHTML)
I want to write the data to a file which in an format that is only understandable by my program, and if any one opens it in notepad must not be able to read(understand) it.

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?

I'm looking at an old web app I wrote and it is taking about an hour to read 4500 records from a DataTable so it can write them to a CSV file.
The DataTable contains... 376 columns
At least, I think that's what Excel's NL column converts to. I just looked up the column count now and had no idea there were so many. Our software vendor hasn't realized the value of dynamic sql statements for this process, so every software "upgrade" just keeps adding more columns rather than only selecting the ones needed. I cannot alter the SQL statement that generates the data
Depending on the data type, the data needs to be formatted in a specific format Data does contains special characters, such as commas The slow part is reading the data. Getting the data from the SQL server and writing it to a CSV is fast.
Here's the code. Forgive the mess, I wrote it back when I didn't know what I was doing and when I still was working in VB
Function ReadDataTableForCSV(dt as DataTable)
Dim sb = New StringBuilder()
Dim dataTypes As New Dictionary(Of String, Integer)
