Sharkawy,

Does perhaps the html file Details.htm or any of the other html files referenced in code contain a link to any image on the c:\ drive? If so, your web app does not have permission to it. Move it to the web folder, and make a relative path to the image.

You are not making it very easy for us to help you...

Please tell us which line generates the exception. Based only on the error, you are trying read from or write to the c:\ which the IIS process won't likely have permission to access.

Access to the path 'C:\ is denied.

**Exception Details: **System.UnauthorizedAccessException: Access to the path 'C:\ is denied.

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 and IIS 7, and the configured application pool identity on IIS 7.5) 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.

Source Error:

The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:

1. Add a "Debug=true" directive at the top of the file that generated the error. Example:

 <%@ Page Language="C#" Debug="true" %>

or:

2) Add the following section to the configuration file of your application:

<configuration>
 <system.web>
 <compilation debug="true"/>
 </system.web>
</configuration>

Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.

Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.

OK, so the error seems to be caused by a reference to an image..?

The code in your original post, in which method is it located? Does that method contain any other code that could be causing the error? Because I can't find any references to the code you posted in the stack trace...
