Hi,

I have a web application, when I run it in Visual Studio 2010 then there's no problem. I were able to connect to my database (select, update, delete) from my web app.

But when I deployed my application to IIS7 I encountered the below error. Please kindly advise if you know the cause of the problem. Thank you.

Hi ambarishtv,

I have tried the link that you provided but it is not working. still i got the same error.

I have tried using the below connection:

<connectionstrings>
<add name="Videos" connectionstring="Provider=Microsoft.Jet.OLEDB.4.0; Data Source={0}App_Data\Videos.mdb" providername="System.Data.OleDb">

public static string ConnectionString = string.Format(ConfigurationManager.ConnectionStrings["Videos"].ConnectionString, HttpContext.Current.Server.MapPath("~/"));

With the provider as System.Data.SqlClient coz i'm using SQL.
