.net - Read A Settings Value From The Web.config File In An ASP.NET Application?
Aug 18, 2010
I'm trying to use the following command:
Dim xmlFilePath As String = _
System.Configuration.ConfigurationManager.AppSettings("XmlFilePath")
to retrieve the following setting:
<applicationSettings>
<MySolution.WebProject.My.MySettings>
<setting name="XmlFilePath" serializeAs="String">
[Code]....
However, xmlFilePath shows up as Nothing after that line of code is run.
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.

I have created a settings-file for my plug-in-based app. When the mainApp writes the settings to the file, the pluginApp should read the settings from the settings-file (when opening or at runtime even better), but somehow it reads the settings from the app.config-file. This means that the pluginApp never will read the settings according the values of the file.

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.

I have been searching and posting regarding this problem and have found nothing to aid me. Discussion is either on web.config files or deal only with external files for connection strings or earlier versions of vb.net not 2008.I have already successfully put connection strings into an external config file, but trying the same approach with application settings has failed.There are two sections of the app.config involved with application settings.
1. the configuration and config sections at the top of the config. file where the section group and the section name are described.
2. the actually data for the application settings by section group section name which appears in the body of the configuraton section of the app.config.[code]

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'm having trouble with my application settings and I'm wondering if anyone else has seen this.
I have a Librabry with a connection string. In the project for the library it has its own app.config:
<configSections>
<sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
<section name="OBInfrastructure.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</sectionGroup>

I am trying to create an msi install for my windows service. The reason for creating an msi is that the intended users want to be able to quickly install the service with as-little intervention as possible.
i can get the service to install as a msi but i have a variable within my code that i need the user to define when the msi is being installed. the variable i require from the user is the file path which they want the xml files my service creates to be located.
i thought i could configure the app.config application settings to contain the file path that the xml files should be written to. However i'm struggling to do this and im not to sure if its the best way to do it?
I have my setup project that contains my executable and has my textbox which will contain the one variable from the user.I have an installer class which contains my serviceinstaller and process installer. This is where im struggling to understand what i need to do next. Do i need to override the install method? The current code of my installer class was automatically generated and is as follows:

I would like to tweak some of the numbers in the app.exe.config file while the program is running. I would like my program to re-load those valued from the edited txt file.
I have tried my.settings.reset, reload, and upgrade. None of these seem to reload the values from the config file into the program
vs 2005
vb.net
How can i get my program to re-read the config file into its memory once it is up and running. say when a button is clicked?

I am writing an application that will be used to extract information from any one of three different database applications, depending on the option selected. I would also like it to be possible to run it against one of several environments (e.g. development, test or live).
I plan to hold the relevant logon details (in encrypted form, of course) in the app.config file, with the appropriate details selected depending on the environment and application. Rather than have each option hard-coded into a Select Case statement, I want to be able to nest the variables in the app.config. I had envisaged a section of the config file looking like this:

After reading through a bunch of stuff, I was curious what production developers use for config files. I know that there is an app.config file that can be modified by the user of the program w/ settings. I also know I can create my own .xml file or .ini file to store settings as well. I wanted to know from the production side, what do you use and why?

I'm looking for a way to specify the location for the User.config file that is used for storing the My.Settings object. It appears that this is not possible. The problem for me is, I don't want to be responsible for creating several different files on the users computer that really have no use and are difficult to find and clean once an update is released. For most users, this is not a serious problem, as many will probably never update the software, and most will probably only go through a couple of updates. On my system, there are config files for every build of the application, and the same to a lesser extent will be true for my beta testers.
I can understand that MS wants to make sure that no two applications will use the same location for storing application data, but a simple [UserData] [CompanyName][ApplicationName] for storing application data will probably suffice for 99.9999 percent of the legitimate applications in the world. Bogging a user's system down with erroneous files, no matter how small, is an unnecessary drain on system resources and a potential source of problems for the user. It's bad enough that most programs leave bits and pieces of themselves all over a user's system after De-installation - this to me seems only to exaggerate this problem.
Is the only way to get around this problem to write a whole new Settings Class? Is there a way to change the location of the UserConfig file to a more friendly (and more predictable) location that I am not finding for myself? It would seem that having at least the OPTION to specify a location for the User.Config file would be OBVIOUS and easy to implement, so why did they leave this out?

I am just not happy with the fact that the user.config file gtets saved in the user's account folder. Is there a way to save it in the Application's Startup Folder instead? I couldn't find any configuration properties within the PROJECT PROPERTIES which would let me change the file location.

I know that when using my.settings that when I exit my app that it saves them and then next reload it imports my.settings back.
My question, is there a way to create this user.config file on the apps first load?

Is there a really simple way to save the app.config file to a location then load it again? I'm making a multiclient app. I was planning on having each user have a folder, and in that folder would be their personalized app.config file that would load when they log in. I don't really know any XML.

I have a class library (Named ADI), that needs some configuration settings from the project using it (like connectionstring, filesystem locations etc).
I want to define these settings in my Windows Forms/Web Projects App.Config or Web.Config, like other settings.
Here is part of my app.config for my windows forms application:

I have VB.net console application. I would like to read the (ConnectionString) from a web.config.
Web.config is located at a particular path in my virtual PC, say "C:/mywebConfig"
<add name="MY_DB" connectionString="Data Source=DATASOURCE;Initial Catalog=DB;Persist
Security Info=False; User ID=***;Password=****;" providerName="System.Data.SqlClient" />
My code:
Dim connString As String = String.Empty
connString = ConfigurationManager.ConnectionStrings("MY_DB").ConnectionString
Whenever I try to access it, i get the error not set to an instance of an object or something like that :)
I tried to add the web.config in my Project, but still get the error.

I recently changed application settings to be in an encrypted config file.The first time I run any application and try to retrieve a setting (My.settings. ...) from the config file I get an Unrecognized attribute 'configProtectionProvider'If I restart the application I don't get an error due to the fact that it doesn't re-encrypt during that run. Why when I run the application for the first time am I getting this error?
I am encrypting the config file on application startup using the following code:

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.

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.

I bet someone already asked this but i cant seem to find it. Ok i need is a global settings that can be updated which will affect all users. I was using xml files in the program filestill now and I need to get around using this because the files can be delete or over written incorrectly. I started using the settings option and realized application level is read only and i cannot use user scope because then it wont be global settings. Is there an alternative to this.

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)

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.

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.

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"?>
<configuration>

Every time I compile my app and the version number changes (I have an auto-incrementing build number), I lose the user-configured app.config settings, since they're stored in the AppData folder for a specific version. Essentially, every release of my application starts from scratch as far as user settings go.
While this is a mild annoyance in development, it raises the question as I approach deployment/release - if I use the app.config to store my user settings, will the user's personalized settings be hosed every time they install a patch that changes the version number of my app? If so, is there an easy way to "upgrade" the settings from the previous release? I know that using HKCU in the registry is another option, but I like the ease of the My.Settings namespace, and I'd like to stay with app.config.

Heres what I need:
1. A way to save settings (Exp.: userkey=randomkey)
2. A way to than read these settings from inside the form.
3. A way to convert settings to strings.
4. A way for users to edit settings
5. No external files.
