To rectify this error, we need to install a utility named aspnet_regiis –i (ASP.NET IIS Registration Tool) from the command prompt. It can be found here: %windir%\Microsoft.NET\Framewor

The .NET framework throws error when we try to enter text which looks like an HTML statement . The text doesn't need to contain valid HTML, just anything with opening and closing angled brackets ("<...>").
The reason behind the error is as a security precaution. Developers need to be aware that users might try to inject HTML (or even a script) into a text box which may affect how the form is rendered
This checking was not performed in the .NET 1.0 framework and was introduced with the .NET 1.1 framework.
The remedy is in two parts and you MUST action both:
<%@ Page Language="vb" AutoEventWireup="false" Codebehind="MyForm.aspx.vb" Inherits="Proj.MyForm" ValidateRequest="false"%>
Alternately, you can globally turn request validation off (but in which case be sure to implement item two below). To globally turn request validation off add the following to your web.config file:
this should go within the
With request validation turned off, users will be able to enter html into text boxes on the page. For example entering:
will be rendered by the browser (when the form is updated and the contents redisplayed) as JavaScript and a message box will appear with the message "Hi Amit". This is generally considered to be undesirable!
Unless you actually need users to be able to enter HTML you must convert the string to its html encoding equivalent - basically this means that certain characters (like "<") are converted to codes (so "<" is converted to "<"). To perform this conversion use HttpUtility.HtmlEncode, for example:
MyTextBox.Text = HttpUtility.HtmlEncode(MyTextBox.Text);
You only need to consider this for any text that will be rendered in the browser.
DataView dv = dt.DefaultView;
or you can use this two functions
//Calling from some function
dt = SelectDistinct(dt, "coloumName");
///////////////////////
public DataTable SelectDistinct( DataTable SourceTable, string FieldName)
{
DataTable dt = new DataTable();
dt.Columns.Add(FieldName, SourceTable.Columns[FieldName].DataType);
object LastValue = null;
foreach (DataRow dr in SourceTable.Rows)
{
if (LastValue == null || !(ColumnEqual(LastValue, dr[FieldName])))
{
LastValue = dr[FieldName];
dt.Rows.Add(new object[] { LastValue });
}
}
return dt;
}
private bool ColumnEqual(object A, object B)
{
if (A == DBNull.Value && B == DBNull.Value) // both are DBNull.Value
return true;
if (A == DBNull.Value || B == DBNull.Value) // only one is DBNull.Value
return false;
return (A.Equals(B)); // value type standard comparison
}
I have written an application in asp.net where I have to write an Xml file through IIS server but I was getting this error:
Access to the path "C:\.... \viewRss.xml" is denied.
Exception Details: System.UnauthorizedAccessException: Access to the
path " C:\.... \viewRss.xml " is denied.
And the solution given by the MS on the error page was:
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
(typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET write 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.
I have tried all this but was unable to write on the file.
The solution I got was with the help of my friend (
After this I was able to write on the xml file.

Then
i. tar -xzf FlashMediaServer3.tar.gz
i. ./installFMS
i. ./fmsmgr server fms start.
that's all
