I have a db connection string 'ApplicationServices' defined in the connectionString section of web.config and 3 Entity Framework connection strings which have the provider connection string attribute with the same connection string as the one in 'ApplicationServices'. Is there a way to reference connectionString in 'ApplicationServices' for the provider connection string attribute of the EF connection string in the web.config, rather than providing the connection string all over again?

I know that most people store the Database connection string inside the web.config file.
But my question is if we move the web.config file from dev to prod then we have to change the connection everytime.
how can we have a connection string that we do not have to change when we move our code from dev to prod.

To give some background details, I have created a website for a friend that has a few pages that require a database in the background. I've used Visual Studio templates for most of it, so there's the standard ASPNETDB.MDF file that's created for users and groups, a login page and a page to view and manage those users etc etc. The login page uses the standard controls for logging in, retrieving lost passwords and so on. Being standard controls, by default they get the connection string from the web.config file. Upon attempting to upload the site to my host (1and1.co.uk in case anyone else has any dealings with them) I discovered that storing the connectionstring doesn't work. 1and1 support say that the sql databases can only be accessed using scripts like this (this is an example of theirs):
<html>
<title>Queries from the MS-SQL database with ASP</title>
<body bgcolor="FFFFFF">
<h2>Query from table <b>products</b> with ASP</h2>
<%
Set conn = Server.CreateObject("ADODB.Connection")
conn.open "PROVIDER=SQLOLEDB;DATA SOURCE=mssqxxx.1and1.com;UID=dboxxxxxxxxx;PWD=xxxxxxxx;DATABASE=dbxxxxxxxxx"
'This code block will create a recordset
Set rs = Server.CreateObject("ADODB.Recordset")
SQL = "select * from products"
rs.open SQL, conn
'will iterate to display the records got from the database
While Not rs.EOF
response.write(rs("id") & " " & rs("price"))
rs.MoveNext
Wend
'closes the connection
rs.close
conn.close
Set rs = Nothing
Set conn = Nothing
%>
</body>
</html>
So my question, is it possible to get the standard asp.net controls to access a database through a script like this?

I'm working on an application that is connected to the online MSSQL database and everything is working fine.The model I'm using is entity model.The problem is that I have to change the connection string from the online database to the local one,but I don't know how.Creating new model isn't an option.I tried changing the connection string in web.config,but errors are the only thing I get.
This is what I have in web.config:
<connectionStrings>
<add name="PravosudnaAkademijaEntities" connectionString="metadata=res://*
PrakModel.csdl|res://*/PrakModel.ssdl|res://*/PrakModel.msl;provider=System.Data.SqlClient;provider connection string='Data Source=HRVOJE-PC;Initial Catalog=pak_baza;Integrated Security=True" providerName="System.Data.EntityClient" />

i am receiving this error when trying to use my membership provider: After googling the error most peoples problems are fixed by removing the old connection string first but this has not worked for me.
I have used a simple custom memberhip provider with one table.

The SSE Provider did not find the database file specified in the connection string. At the configured trust level (below High trust level), the SSE provider can not automatically create the database file.Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.

I have a very basic web site that uses a standard login control. It was original built using ASP.NET 2.0, and when I preformed a few site improvments, VS 2010 upgraded the site to version 4.0. Locally, everything is fine. But live, everything is working except the login authentication. All other pages that use the database work fine.
does the upgrade process affect the database? As this is the only thing I've not replaced on the live server.
The error I get with the login is:
The SSE Provider did not find the database file specified in the connection string. At the configured trust level (below High trust level), the SSE provider can not automatically create the database file Any thoughts?

I just want to know, What parameters or attributes should be taken in connection string so as to handle high traffic enterprise applications? Like in general we use server, initial catalog, userid, passwd. Some times we add timeout , and in some scenario pool etc. But i don't know what attributes should i take in as my common practice apart from above.

I am developing an application in which I can connect to the ASPNETDB.MDF if it is on my machine, however, when I want to put it on another machine and try to remote connect it, I get the error:
An error occurred while attempting to initialize a System.Data.SqlClient.SqlConnection object. The value that was provided for the connection string may be wrong, or it may contain an invalid syntax.
Parameter name: connectionString and my connection string is as follows:

I have a database on Go Daddy and my VS2008 app can not access it via web.config connection string. Of course runs great locally in development. I copy/pasted the connection string information from Go Daddy exactly into my web.config file. Web site runs fine on the web but when I try to Login at my login page, i get :The SSE Provider did not find the database file specified in the connection string. At the configured trust level (below High trust level), the SSE provider can not automatically create the database file.
I used VS2008 to create the .sql script files and uploaded them to Go Daddy and the Go Daddy people say everything works as they and I can both Login to the database from within GoDaddy.The database i am trying to access consists of the a ASPNETDB.mdf and another Database.mdf together as one in the Go Daddy database.
here is what i used: <connectionStrings><add

connectionString="Data

I've done this before but can't remember how for the life of me. I used aspnetreg_sql.exe to create the membership tables in my database. But now i cant seem to be able to point my web app to the correct database. In the provider settings in asp.net management interface i only see a radio button with the label "AspNetSqlProvider" but I can only test it (in which it always fails). I can't modify the connection.

I am using VS2008 and oracle 10g ODP.Net. The oracle database that I used in the connection is working and tested it using sql plus.The connection string when used in a GriDView works perfectly. Now when I created a new listview control with the same connection it gives an error.Database schema could not be retrieved for this connection. Please make sure connection settings are correct and the database is online

I am preparing for an Access2007 db conversion at the beginning of the year and would like to know what the best process would be for connecting to the sqlserver2005 database. I have read about adding the connection string to the web.config file. I have also read about using ADO.NET and put the connection information into a class and not the web.config file.
I would like to hear from others as to what you have used, are using, or plan on using for a webapp (vs2010), and why so I can get an understanding.
