I'm starting to consider creating a class library that I want to make generic so others can use it. While planning it out, I came to thinking about the various configuration settings that I would need. Since the idea is to make it open/shared, I wanted to make things as easy on the end user as possible. What's the best way to setup configuration settings without making use of web.config/app.config?

I have a .NET 4 class library project, which is used by multiple web projects. In this class library I need to get a DB connection string and it needs to be the same for all the web projects. Currently I've got it as a setting in each web.config file, but this is not ideal. Is there any way I can have that configuration stored with the DLL, but still allow it to be modified at runtime (ie. hardcoding the connection string is out)?
App.config seems to be generally ignored for a DLL, even though it does get renamed to assemblyname.dll.config and copied to the bin directory for the web. I tried making it an "application setting" (ie. using the auto-generated class derived from System.Configuration.ApplicationSettingsBase) and this appeared to work, but changing the value in the DLL .config file at runtime had no effect, so I suspect it's really just using the hardcoded default value of the setting.
My question relates to the performance implications of reading application configuration data from an XML file.I am building an application that lists information from a database and needs to know how to display the lists, depending on the types of data returned.This is difficult to explain, but basically I would like to have an XML config file that lists the types and describes how to display them. This will allow me to change the display methods without re-compiling the application.
My question is really around performance. Given that my application will need to use this data many times during each page load...Should I be reading directly from the XML file and parse it each time I need it?
Or should I cache the XML object and parse it each time I need it?Or should I parse the XML once, generate some sort of object and cache that object?My guess is option 3, but I'm basically fishing for best practice around this.
Web.config is the main settings and configuration file for an ASP.NET web application. The file is an XML document that defines configuration information regarding the web application. The web.config file contains information that control module loading, security configuration, session state configuration, and application language and compilation settings. Web.config files can also contain application specific items such as database connection strings
Example 1:
<!-- This is an example Web.config file -->
[Code]....
In this article, we will see how to read the configuration settings in the web.config using 'JavaScript'.
Step 1: Create a new ASP.NET website. Add a button control to the Default.aspx.
Step 2: Right click the project > Add New Item > Web Configuration File
Add the following sample entry to the appSettings section in the web.config between the <configuration> tag as shown in the example 1:
<add key="var1" value="SomeValue"/>
Step 3: To read these entries using JavaScript, add the following script in the <head> tag of your Default.aspx page as shown below:
<head runat="server">
<title></title>
<script type="text/javascript">
function ReadConfigSettings()
{
var v1 = '<%=ConfigurationManager.AppSettings["var1"].ToString() %>'
alert(v1);
}
</script>
</head>
Step 4: Call this function on a button click and display the values of the configuration settings
<input type="button" value="Get" onclick="ReadConfigSettings();" />
That's it. Run the application and click the button. The value of the key in the appSettings will be displayed in the alert window. I hope you liked this short article.
I am designing a web application for Leave Application of our faculties. There is a form in my website which represent the existing paper-back leave application form. Users(faculties) have to fill-up this web form and after validation an email will be send to the email address of our principal/hod. I hope that email address(s) will be provided to our group members. Now I want to know that what will be the required configuration of the web.config file? I found this blog ScottGu's Blog. Here the given configuration is:
[Code]....
But I think this is not acceptable for my project as the smtp from="test@foo.com", userName, password are unknown to me. So what should I do. Am I able to understand my requirement to you?
What it best location to store various configuration settings of a web site modules. Creating class (that inherit ConfigurationSection) that map the settings in web.config file?Or creating some DAL and BLL clases that work with database?
View 5 RepliesI've been thinking about this for a couple days but still would like some feedback on the best way to go about this:
I have multiple sites (domains) that will be running the same code. However, there are a couple settings I have in the appsettings web.config file which are relative to each site. (ie: defaultSiteTitle, emailFromAddress, etc).
I would like to deploy this application in only one location (folder) and point the domains in IIS to that one directory.
To do this, I believe I cannot use the web.config file to hold these settings...
So, I decided to make a SiteSettings.xml file and load the site settings in there:
<sites>
<oSite domain="abc.com" defaultSiteTitle="This is Site ABC" emailFromAddress="info@abc.com" />
<oSite domain="xyz.com" defaultSiteTitle="This is Site XYZ" emailFromAddress="info@xyz.com" />
</sites>
So when I need to access the site settings I just call a function in my datalayer that reads this xml file and via the httpRequest I pass it it determines which site settings to use.
Okay, that works when I call it from a page where I have the httpRequest...
Howver, now when I'm into some business layer functions say sendEmail and I need to find the emailFromAddress from the SiteSettings.xml file, I don't have the httpRequest. I know I could probably hack something together and pass it someway...
But I'm trying to figure out the best way to do this...
I don't really want to store it into session.
Is it possible to tell IIS what web.config file to look at, if I had multiple web.config files? (I don't think this is possible).
I have this portion of my web.config file;
[Code]....
I need to be able to retrieve the value of "from" in my application. How do I read this value into my code?
I'm just wondering what the best practice is for managing web.config connection strings and SMTP settings when working locally in VS2008 and deploying to a remote server?
View 5 RepliesThis is a general question and is not about any particular issue that I am facing right now.As configuration settings in the child level can override the ones in parent level,errors can occur when you have 2 web.config files one redefining configuration settings that you cannot override such as authentication or session state.Issue happens when you have authentication / session state set on the lower level web.config and also in higher level web.config. Is there any other configuration settings like these ?
View 1 RepliesI have few settings which I could place in a separate XML file and have them accessed in the Web app. Then I thought (thinking of one additional file to deploy), why not have them in the web.config itself. However, just because I need to have custom nodes, I can not have the settings under . So, I am thinking of creating a custom config handler following this. Would that be better than having a separate XML file? Is It going to be an overkill or performance wise? Is there a better way to go?
View 1 RepliesWe are experiencing some strange behaviour on one of our ASP.NET web servers (Windows 2003 64-bit). After some activity, two third-party controls are unable to run correctly. One is log4net (it does not write error messages out) and the other is a menu control (it displays eval message instead of picking up its license). The one common thread is that both controls pick up their config from external config files (linked to from web.config).
Just wondering if anyone has any thoughts on this or experienced this in any way. Is it related to file/folder rights? The server has been running fine for a while and just started exhibiting this behaviour. Perhaps it occurs around the time the worker processes are recycled.
I have many Connection strings in my web.config file. I also have a "dataConfiguration" setting in the same file which specifies what database my app connects to.
How do I read the "defaultDatabase" setting / section from the, see below xml file.

So I am using C# ASP.NET 3.5 and I would like to add a feature to my site to turn on and off a sort of debug mode for testing purposes.
Is there a best way to have a file or class that stores or returns simply if myDebug is on or off. It has to be accessed fast since it will be used a lot on multiple pages and it should be easy to set using the website itself.
My first thought is just a class with get/set which is stored on every page... perhaps the master page?
I have some global settings in my application that is going to be handled by the administrator and I store them in the database.
Settings like: board on/off, max items/page on different UserControls, language, hide/show modules.
What technique should I follow to read the values in the database and display the page or the application according to it .. Of course I could do it the easy way and fetch the required settings for each page in the Page_Load event handler but I think that will be a lot of database connection!
I am evaluating ASP.NET Membership for an intranet Silverlight app. I want users to be automatically authenticated for my application with their windows logon. Thus I configured Windows Authentication. I would like to store user settings like email-address in using the SqlMembershipProvider and not AD. It seems that storing user settings using the SqlMembershipProvider is not supported with Windows Authentication. Is this really so (using .NET 4)?
If so: What is the rationale behind this? IMHO authentication, user settings and authorization are distinct aspects. User settings could easily be stored (identified by user name) using the SqlMembershipProvider with authentication and password management being supplied by Windows. What is the recommended solution for my scenario?
I noticed that we always just are like:
SmtpClient mSmtpClient = new SmtpClient();
// Send the mail message
mSmtpClient.Send(mMailMessage);
And the only place the credentials are set are in web.config:
<system.net>
<mailSettings>
<smtp>
<network host="xxx.xx.xxx.229" userName="xxxxxxxx" password="xxxxxxxx"/>
</smtp>
</mailSettings>
</system.net>
So my question is, how does it automagically get them out?
I can't seem to find this answer anywhere on google or stackoverflow, even though I'd thought it would've been an easy thing to do.
I want to understand how the system.web authorization tag on the web.config works, and what exactly each attribute and property does.
For instance, what does
<system.web>
<authorization>
<deny users="?"/>
<allow users="*"/>
</authorization>
</system.web>
Specifically what I want to do is to disallow access to most of the site for unauthenticated users, allow access to some of the site for authenticated users who belong to a certain role, and allow full access to users from a second role.
This might sound a bit dumb. I always had this impression that web.config should store all settings which are suspect to change post-build and setting.settings should have the one which may change pre-build.but I have seen projects which had like connection string in setting.settings. Connection Strings should always been in web.config, shouldnt it?I am interested in a design perspective answer.Just a bit of background:My current scenario is that I am developing a web application with all the three tiers abstracted in three separate visual studio projects thus every tier has its own .settings and .config file.
View 2 RepliesI want to know what best practice is for accessing settings in config file when you have dev/test/production types.
If you have different config for each type when you publish a ASP.NET website doesn't the config get copied as well??
Is it possible to configure your web.config file of your asp.net website to use different settings for users accessing the site via HTTPS?
(eg. I need to have validateRequest attribute for https access set to false, but for internal access (using http) set to true...)
whats a good way to test the settings (especially keys) in web.config? I think its not really testable with NUnit, or is it?Example: <add key="SomeKey" value="SomeValue" />
View 2 RepliesI've created a web page and it contains some settings value in web.cofig for example images.So i want to give the path of images in Web.Config file and file name in that particular image src. I wanted to read that settings only in aspx page not in codebehind. For example Web.Config: <add key="ImagePath" value=[URL]> and in my aspx page, <img id="ImgHeader" runat="server" src="<%ConfigurationManager.AppSettings["ImagePath"]%>" />
View 2 RepliesI have an ASP.NET site which uses a 3rd party activeX control. I have to pass a few parameters to the OBJECT tag in the HTML page. If i hardcode these parameters into the HTML everything works.
I would like to place the parameters in my web.config with app settings "key/value" pairs.
My problem is i cannot read the app key setting in the HTML markup to succesfully pass them in as parameters. I can read them fine from server side code behind.
What's the correct way to read these settings in the client side HTML markup ?
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">
<value>C:ASP.NETFolderMessageLog</value>
</setting>
</MySolution.WebProject.My.MySettings>
</applicationSettings>
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.
