ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

How to set default values for custom configuration collections

ShadowCharmer — Wed, 30 Apr 2008 04:00:00 GMT

I've been working on a custom configuration section for my .NET web application, and I've almost got it working but there's one thing that I still haven't cracked.

I'm trying to model my web.config file so that it looks like this:

<configSections>
	<section name="Hydrogen" type="Hydrogen.Configuration.RootConfig, Hydrogen" />
</configSections>

<Hydrogen	siteName="Test Application..."
		showDebug="true"
>
	<languages>
		<add id="en" culture="en-GB" />
		<add id="cy" culture="cy-GB" />
		<add id="en-us" culture="en-US" />
	</languages>
</Hydrogen>

However, I'd like the <languages> section to be optional, and to programmatically provide a default list of languages should none be provided in the config file. Setting defaults for simple types was straightforward, as I have done for both the 'siteName' and 'showDebug' properties below, but how do you go about providing defaults for a collection element?

The code I have so far is below.

RootConfig.cs

public class RootConfig : ConfigurationSection
{
	[ConfigurationProperty("siteName", DefaultValue="unnamed site", IsRequired=true)]
	public string SiteName
	{
		get { return this["siteName"] as string; }
	}

	[ConfigurationProperty("showDebug", DefaultValue=false)]
	public bool ShowDebug
	{
		get
		{
			bool result;
			if (! bool.TryParse(this["showDebug"].ToString(), out result))
				result = false;

			return result;			
		}
	}

	[ConfigurationProperty("languages", IsRequired = true)]
	public LanguageCollection Languages
	{
		get { return this["languages"] as LanguageCollection; }
	}
}

LanguageCollection.cs

public class LanguageCollection : ConfigurationElementCollection
{
	public LanguageElement this[int index]
	{
		get { return base.BaseGet(index) as LanguageElement; }
		set
		{
			if (base.BaseGet(index) != null)
				base.BaseRemoveAt(index);

			this.BaseAdd(index, value);
		}
	}

	protected override ConfigurationElement CreateNewElement()
	{
		return new LanguageElement();
	}

	protected override object GetElementKey(ConfigurationElement element)
	{
		return ((LanguageElement)element).Id;
	}
}

LanguageElement.cs

public class LanguageElement : ConfigurationElement
{
	[ConfigurationProperty("id", IsRequired = true, IsKey = true)]
	public string Id
	{
		get { return this["id"] as string; }
		set { this["id"] = value; }
	}

	[ConfigurationProperty("culture", IsRequired = true)]
	public string Culture
	{
		get { return this["culture"] as string; }
		set { this["culture"] = value; }
	}
}

Any suggestions, anyone?

Many Thanks,

declare connection string in app.config in WPF

kpxkpx — Sat, 05 May 2007 04:00:00 GMT

Dear all,

Here is my question. I am trying to build up a object data source that will to be bound to xaml object in WPF. After I declare a connectionString in app.config of object data source project, the connectionString can not be found and show the error below:

"Object reference not set to an instance of an object."

app.config file:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<connectionStrings>
<add name="Connection" connectionString="Data Source=***;Initial Catalog=***;User ID=***;Password=***" providerName="System.Data.SqlClient"/>
</connectionStrings>
</configuration>

cs code:

string _connectionString =ConfigurationManager.ConnectionStrings["Connection"].ConnectionString;

Can any one tell me what I did wrong? Many thanks.

______________________________________________________________________________________

After that, I though that it may be work if use connection string in code, but I got new error as below:

"Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."

CS:

string _connectionString="Data Source=***;Initial Catalog=***;User ID=***;Password=***" ;

SqlClientPermission permission = new SqlClientPermission(PermissionState.None);
            permission.Add(_connectionString, "", KeyRestrictionBehavior.AllowOnly);
            permission.PermitOnly();

string sqlCmd = "select * from OBJ_WORK_ITEMS where ITEM_ID=38";

SqlConnection conn = new SqlConnection(_connectionString);
SqlDataAdapter da = new SqlDataAdapter(sqlCmd, conn);

DataSet ds = new DataSet();

            try
            {
                conn.Open();
                da.Fill(ds, "OBJ_WORK_ITEMS");
            }
            catch (Exception ee)
            {
                throw new Exception("Something wrong in da.fill()" + ee);
            }
            finally
            {
                conn.Close();
            }

You can see I tried to modify SqlClientPermission to make it work, but no luck. Please help me!

Supporting configSource attribute on custom ConfigurationSectionGroup

sandor — Thu, 26 Apr 2007 04:00:00 GMT

I would like to support the configSource attribute on my custom ConfigurationSectionGroup in order to allow for storage of the group contents in an external .config file. Unfortunately, I have no clue how to do this in a proper manner, other than writing custom code that loads and processes the external file. The latter is probably not a good idea because the logic is allegedly available in the .NET framework (as some of the built-in section groups, like <profiles> support it), though I don't know how to make use of it.

ASP.NET 2.0 Hosting (Root and Sub Direct with Different Web.Config in Same Domain)

khiteam — Thu, 01 Mar 2007 05:00:00 GMT

Hi,

I want to config Production Server Database and Staging Server Database Connection String in Same Application depends on Location path.

Example. www.webapp.com (Root Directory)

When I browse this site the production DataBase Server Connection String should be called through Web.Config of root directory.

Example. www.webapp.com/LiveBeta (here ‘LiveBeta’ is a Sub Directory)

When I browse this site the Staging (Testing) Database Server Connection String should be called through Web.Config of sub directory.

Both the root and sub directory are same application.

How can I maintain both the application in one server with different Web.Config files depending on the directories?

I tried it out but received the error as connection string conflict.

How can toggle this issue in ASP.NET 2.0 with 2 Database in same server?

It's very urgent one.

Thank you,

Bhavani
