0x80040E21 Error Trying To Move From Access To Sql Express

Hi

I am tearing my hair out. I have tried upgrading form access to sql express. I have built the database and written all of my stored procedures. I think I am having problems with connecting to the server. I am storing my connection in the web.config. I am trying to open the datbase and add populate a reader, but i keep getting the error:

Exception Details:

 System.Data.OleDb.OleDbException: No error message available, result code: DB_E_ERRORSOCCURRED(0x80040E21).

Any help would be much appreciated. Code below:


<connectionStrings>

 <add name="SQLProducts" connectionString="Provider=SQLOLEDB.1;Server=(local)SQLExpress;Database=laptopsqlexpress.ALLBUTYOUDB;Integrated Security=yes;"/>

</connectionStrings>

 

Function GetCategoryProductNav(ByVal strCategoryID As String) As OleDbDataReader

 Dim objReader As OleDbDataReader

 Dim objCmd As New OleDbCommand("spGetCatProductNav", objConn)

 objCmd.CommandType = CommandType.StoredProcedure

 Dim objParam As OleDbParameter

 objParam = New OleDbParameter("@CategoryID", OleDbType.Integer)

 objParam.Value = strCategoryID

 objCmd.Parameters.Add(objParam)

 Try

  objConn.Open()

  objReader = objCmd.ExecuteReader

 Catch ex As Exception

 Throw ex

 End Try

 Return objReader

End Function
