Hi experts how are you all? i am student, and learning asp.net c# visual studio 2010 with using sql server 2005. I have developed a website which has database. I developed this website with self studies taking help from internet. the website is completed and working perfectly in my computer.

I have hosting server and domain name registered already.

the problem is when I upload my website it doesn't work there the following error displays:

HTML

Server Error in '/' Application.

Runtime Error

Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. 

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".


<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration>

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.


<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
    </system.web>
</configuration>

I read somewhere in internet that I must configure my web.config file before I upload website to the hosting server. In my website web.config file has following information by default,

XML

<?xml version="1.0"?>
<!--

  -->
<configuration>
    <connectionStrings>
  <add name="SPConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\ShoppingPortal.mdf;Integrated Security=True;User Instance=True"
   providerName="System.Data.SqlClient" />
 </connectionStrings>
    <system.web>
        <trace enabled="true" localOnly="false" pageOutput="true" />
  <compilation debug="true" targetFramework="4.0"/>
    </system.web>
</configuration>

I don't know what should I edit in it to get it work on hosting server please help me in this regard that what should I do with this. Thank you in advance

The problem may - or may not - be in your site configuration. The first thing to do is to find out where the problem actually is: which means looking at the error message and doing exactly what it says. When you have done that - and the instructions are pretty explicit - when you run your site again, the error will pinpoint the file and line it occurs on.

However, it is probably your connection string - it is unlikely that any production server will use SqlExpress, or site the SQL server on the same PC as the webserver, or use integrated security.
You will need to talk to your hosting service and find out exactly what details you need to use, we can't tell you because each hosting service configures these things differently to suit themselves.
