I am developing web applicaiton. I want to read web.config in App.config file. I have appSettings and connectionStrings in web.config. How to read that?
View 10 RepliesI am trying to read a normal string from the web.config file. When I try to read a string from the web.config file the application doesnt seem to read it. I set my sqlconnection string in the web.config file. It reads a sqlconnection string but not a normal string.Here is my code:
web.config file:
<applicationSettings>
<MyApplication.Settings>
<setting name="Colour" serializeAs="String">
<value> "Red"</value>
</setting>
</MyApplication.Settings>
</applicationSettings
This is how I try to call the setting:
string strColour = Properties.Settings.Default.Colour;
I am using .net framework 4.0
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.
<configuration>
<configSections> [code]....
i have a xml configuration file like below format.
<setting>
<web>
<mailid>xxxx</mailid>
</web>
<network>
<logid>sd</logid>
</network>
</setting>
i would like to programmatically read entry from xml config file which is same as asp.net webconfig file reading.
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.
I'm preparing to deploy a ASP.NET web application. The target server has already a previous version of my web application with parameters specified on the web.config file.
In the new version of this web application, the web.config file contains new sections I would like they appear into the target web.config file on the server.
However I can't find the way to merge the new web.config sections into the existing web.config file ?
Does I have to do it programmatically, or is there a tool to merge the both files during installation ? (I'm using Web Setup Project).
We 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 know how to read a stuff from web.config in .cs file, but how can i read something .aspx source? For example i want to do next <a href="somethingFromWeb.config"></a>
View 1 RepliesWeb.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 -->

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 working on a web app that will heavily rely on configuration. The configuration is also will be written by another process or human. I am looking to get response on best practices in .net 3.5 on how to implement this case. I had used the configuration section of an early version of the Enterprise Library Applications Block. I really liked working with it but from what I hear it is discontinued in current versions. Hence the question... Need to be able to serialize collections, pick up file write event to reload new instance of config into memory.
View 1 RepliesI need to read configuration elements from the web.config. Let this be my web.config.
<family>
<parents>
<child name="Hello"/>
<child name="World"/>
</parents>
<parents>
<child name="Hello1"/>
<child name="World2"/>
</parents>
</family>
So I have something like this, I need to read this into a collection.
<asp:sqldatasource id="DS" runat="server" connectionstring="<%$ ConnectionStrings:MY_CONNECTION %>"
Selectcommand ="Select * from [10.10.10.10].dd.dbo.table">
The connection string is taken from web.config.
I want to take a value from the web.config -> app settings via asp tag.
The reason is that inside the selectcommand inside the sqldatasource I use four-part-name and the IP is hard coded in some aspx files.
I want it to be taken from appsettings property instead.

How to run asp.net application with encrypted web.config ,is it possible note that ASP.NET application have a database with encrypted connectionstring and a "cannot read connection string " message is generated
View 2 RepliesWhen the user clicks on it, another .aspx page should pop up. I used the code below and it works fine. But when we deploy this .aspx page, the IP address of the target IIS server will be different. So I am thinking of saving the IP address of target IIS server in web.config file and load it into the Window.open method of Javascript code (below).Qusetion 1: Is that right way to do? If so, how I can read web.config file from Javascript?
Code:
<script type="text/javascript">
function open_win() {
window.open("http://10.999.1.86/WebUI/HistoricalRuns.aspx", "_blank", "toolbar=no, location=yes, directories=no, status=no, menubar=yes, scrollbars=yes, resizable=yes, copyhistory=no, width=1000, height=500");
I'm trying to use OpenExeConfiguration to read a different config file, but I can't find any good examples.I have a windows Service and some of the config data already exists in another windows service config file on the same server, and it makes more sense to use what is already there, rather than have to maintain the same data in 2 places.
View 2 RepliesI have to duplicate some settings (like connection string) between a web.config file that a WCF host uses and a web.config file that a web client uses.
In the interest of not duplicating, can I have both the web.configs read from a separate xml file? The two web.configs can be entirely in different solutions/projects so I guess this is not possible, but wanted to get other's opinion.
PS: I do understand I can use a database to store all the config settings.
I wonder how often the Web.config file is read by the server?And if the fact of the Web.config file is too large, influences the application performance?
View 2 RepliesI have code that reads a value from a config file (not web.config) given a key. It looks like this:
Code:
Public Shared Function GetCustomConfig(ByVal ValuetoGet As String, ByVal ConfigFileValue As String) As String
Dim Returnvalue As String = String.Empty
LoadConfig(ConfigFileValue)
For Each KeyValue As String In AppSettings.Keys
If KeyValue = ValuetoGet Then
Returnvalue = AppSettings.Item(KeyValue).ToString
End If
Next
Return Returnvalue
End Function
So if my config file which is named my.config has this entry: <add key="TempArea" value="c:Temp"/>I would call GetCustomerConfig("TempArea", "my.config") and the function would return "c:Temp". Most of the time this is what happens. But sometimes I get an exception: Collection was modified after the enumerator was instantiated.
Is there a better way to get the value given the key? This is code written long ago by my predecessor, and I am not sure I want to use it anymore. If I do use it, I will have to do something so that it is more reliable.
Question: I have an annoying problem with nhibernate.The problem is I cannot get any example I find on the web to work... I've now tried for two days...
The first problem was it wouldn't read the config file, so I had to move it into app.config / web.config.
The second problem is that whatever I do, I always get an error:
No persister for: NHibernate.Examples.QuickStart.User
I've searched google and I did change the mapping to embeded ressource, and I did add the mapping to the config file, but nothing helps...
The example is from this page:
https://www.hibernate.org/362.html
I've uploaded my Visual Studio 2005 project to

I have deploy my web site, it contains a project!
in MyWeb there are all the aspx page and some entites datamodel, in MyApp there are the class with function like "getter data from DB" and there is a entity data model.
afeter the deploy, I have only the web.config and the connection string for the entity datamodel....itīs run ok, read/write the data on the DB.
The problem is with MyApp.....after the deploy it is a dll file and I donīt have the app.config and the entity inside it donīt run, not read/write nothing on the DB.
There arenīt error or messager but not read/write the data in the MyApp project.
all run on the iis 7
now...the question is:
I lose the connection string (in app.config) after the deploy?
Can I put a entity in the MyWeb and read it in another project (myApp)?
ps: for connect to DB I use not the c# code:
var db=from x in AccessDB.Example select x;
While using a third party dll I was getting the following exception - "exePath must be specified when not running inside a stand alone exe" with following trace
System.Configuration.ConfigurationManager.OpenExeConfigurationImpl(ConfigurationFileMap fileMap, Boolean isMachine, ConfigurationUserLevel userLevel, String exePath).
The reason I found was that it was looking for app.config and I had provided the details in web.config. My question is why does the system.configuration differentiate between web.config and app.config.
I upgrade my application from .NET 2.0 to .NET 4.0. Everything went smooth, with very few errors. Now the code is compiling fine, but run time environment is loading the configuration parameters from app.config instead of web.config;Here is my setup:Objects project: has app.configUI project: has web.config, When I run this site, it is fetching the configuration parameters from app.config. Any idea if I need to make any changes to read it from web.config instead of app.config? It used to work fine in my previous environment.
View 8 RepliesCurrently, I work on an ASP.NET project which is hosted under version control and is used on several developer machines, tester machine and production environment.
In three cases, configuration (Web.config) may be different. For example, developer and tester environments use testing SQL Server, whereas in production environment, another SQL Server is accessed, so the connection string is different in those cases.
We want to keep three versions of Web.config in subversion. But modifying each of three files every time we need to add, remove or change a common setting is annoying: it would be nice to have a common, master Web.config, which will be inherited by each of the three Web.config files.
How to set up an ASP.NET project which will use a master configuration file and different slave configuration files on different machines, thus sharing the same project/source code/configuration files in subversion?
When I open my ASP.NET site in IIS and try to open the .NET Trust Levels, I get an error message:
.NET Trust Levels There was an error while performing this operation.
Details:
Filename: ?C:inetpubwwwrootmyappweb.config
Line number: 445
Error: This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"),or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".
I've checked a few places, but I haven't found anything that seems like it would be locking that setting. Is there a systematic way of determining where that setting is locked?
I'm using IIS 7.5 and .NET 3.5 sp1.
