I developed MVC application. Then successfully import my local database which was stored in App_Data folder to the hosting provider (thanks
ScottGu). But now I don't realize how can I painlessly change my Entity models which was using local database in order they use database which was imported.Here is some of the connection strings

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'm learning ASP.NET and everywhere and in book that I'm reading now theres connection string named: LocalSqlServer.
I want to use my local sql server database instead of sql express to store Roles, Membership and other data.
I have used aspnet_regsql.exe to create needed data structures in my database. after that I changed my web.config to look like:

my webserver is in the DMZ. The Database in the intranet. For connection from webserver to database the following entry is made in the odbc connection "TCPIP BCAST=NO;HOST=Intranet.Firma.local,Intranet_Spiegel.Firma.local,Intranet_Arbiter.Firma.local;PORT=2639}"
how to get this options in the connection strings working, or how i must modify the entitiy framework connection string to use the odbc entry?
<add name="KA_Entities" connectionString="metadata=res://*/Models.KA_Model.csdl|res://*/Models.KA_Model.ssdl|res://*/Models.KA_Model.msl;provider=iAnywhere.Data.SQLAnywhere;provider connection string="UserID=user;Password=password;DataSourceName=Databasename""
providerName="System.Data.EntityClient" />
<add name="KAPortal" connectionString="UserID=user;Password=password;DataSourceName=Databasename" providerName="iAnywhere.Data.SQLAnywhere" />
I tried to use odbcfor the entity framework, but the Wizard always add the right .NET Provider and not the odbc
I am making a web project now. And i meet some problems working with Entity Framework. My program needs to have dynamic model. I try to explain. So i have classes and database is created from them. At the beginning of work program checks in folder Modules for assemblies and looks for classses that needs to be created as tables in database(this classes have to become a part of ef model). And i need at runtime create database.If some new classes was added so add this tables to database, but not recreate it(as it is made by default). If i delete classes the tables are not deleted.
View 2 RepliesHow can I retrieve the Entity Framework 4 connection string from a custom config file, not web.config?
Edit: Is it reasonable to delete the default constructor generated code and recreate it in a partial class to use the pulled in connection string?
I would really like to avoid changing all references to the EF context with an overloaded method including the connection string.

Is it possible to choose a specific database that will be used with the entity framework? At this time, I use the connection string in the Web.Config as database authentication.
I have twelve databases, each of them has the same structure and the same stored procedure.
There is one database for each client. When a client wants to login into the system, he needs to choose his database name from a listbox.
I would like to create a dynamic connection string which will include the database name chosen by the client.
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'm using Entity Framework 4 for a simple app and would like to bake my connection credentials into the following connection string:
<connectionStrings>
<add name="MyEntities"
connectionString="metadata=res://*/MyDataModel.csdl|res://*/MyDataModel.ssdl|res://*/MyDataModel.msl;provider=System.Data.SqlClient;provider connection string="Data Source=localhostDEV;Initial Catalog=MyDB;UserId=myUser;Password=jack&jill;MultipleActiveResultSets=True""
providerName="System.Data.EntityClient" />
</connectionStrings>
However, the password (which I cannot change) contains an ampersand. ASP.NET throws:
Configuration Error: An error occurred while parsing EntityName. Line XX, position YYY.
If I replace the ampersand in the password with &, I get a SqlException: Login failed for user 'myUser'. Usually this trick works, but I'm guessing that something is failing because this is technically a connection string inside a connection string.
What should I do here? Most of my classes include code like:
using (var context = new MyEntities()) {
// do work
}
Update: It turns out that the credentials I am using are a domain account, so what I really need is Integrated Security=True in the connection string rather than a password.
Encoding the ampersand as indicated in the accepted answer should work fine, though I haven't tested it.
I want to know if I develop and application using entity framework 4.0 and sql server and then changing the connection string to my sql one, will it work without any problem?
What are the other considerations to keep in mind?
I have an ms access db file and now i want to use it in my app. i have given like

but it is giving error to me.If anybody know how to give this connection string for password enabled ms access database,
I have a entity data model generated from a database schema. Now that database is no more physically available, I want to generate a new database with the same schema model. I'm able to generate the tables from the script that the Entity Frame work generates for me.
I have two problems. I'm not able to generate the stored procedures from EDM. Second, I'm not able to change the connection string to the new database. Do I have to re-generate the edm from the new database that I'm trying to create?

I have created a ASP.NET 4 application in VS 2010 using Silverlight and RIA Services.
After finishing the first release on my development pc, I'm starting some deployment testing in a server in my local network.
After sucessfully published the web application using the Visual Studio FTP publishing option, I notice two strange things:
1 - On the IIS properties of the website I have uploaded my files to, you can see now a connection string, named as LocalSqlServer that points to the aspnetdb.mdf database file. I had a look in the web.config file and I could not find this connection strind defined there. So, where is it located? Where did IIs got it from?
2 - As the aspnetdb.mdf file is not deployed withtin the web application and I a musing SQL express in my testing server, where can I drop the mdf and ldf files so they can be attached when the applicaiton runs? I know I can perform an attach operation using management studio,but I'm wandering where is the DataDirectory folder ASP.NET looks for to attach it at runtime?
I have a page in asp.net (web forms) that up until now only had one database for data.
So all the controls that require something from the database use a datasource and the same connection string.
<asp:SqlDataSource id="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:DefaultConnectionString %>"
ProviderName="System.Data.SqlClient"
SelectCommand="SELECT ... ">
</asp:SqlDataSource>
Up until now I only needed one connection string since I had only one database but this has changed since I want some users to connect to database A and others to database B What would be the correct way to go about it?
How can I make the code string connStr = ConfigurationManager.ConnectionStrings "staceys_cakesConnectionString"].ConnectionString;

I have a solution which uses Linq to SQL Data Classes to acced the db. I have a project for my domain objects in my solution, which is a class library and has the dbml file. When I set up the dmbl using the wizard, Visual Studio created anapp.config file on that project with the connection string. It also creatting asettings file with the same info. I've noticed that if I change the connection string in the settings file, the app.config gets updated, which is the expected behaviour.
However, I'm having a problem when I deploy my web site to the production server. I already set the app.config file's Build Action to "Content", and also set Copy to ouput directory to "Always". Nevertheless, when I install the web site and change the connection string in the app.config file, it still takes the old connection string, so obviously I get an error. I've found that it only works if I change it with in Visual Studio and then compile, but of course that's not an optimal solution, because any change in the production db server would mean I have to change my project's assembly, thus generating a new version.
What do I have to configure so that the assembly takes the connection string form my app.config file directly after I deploy?
i have 2 ASP pages in first page the user choose the database name and in other page take the database name and change the connection string to other databasehow i can pass a variable from one page to other by button click and how i receive this variable in other page and how to change the connection stringthe connection string is in web.config like this:
<connectionStrings>
<add name="Northwind" connectionString="Provider=sqloledb;Data Source=.;Initial Catalog=Northwind;User Id=sa;Password=sa; Connect Timeout=10"/>

Right now, when I am copying the website to host server, I am changing the connection string in webconfig file and at each location of a sqldatasource or a query .. thats like more than 30 places where I am doing this.
When I am done copying the website, I have to change all the connection strings back to dev server for me to keep working on the dev copy....
I have decrypted my connection string in web.config file of the application programatically. But after deployment under the ASP.net tab of application virtual directory when I click edit configuration the connection strings in web.config file are visible in decrypted format i.e readable form.
View 3 RepliesI have been preparing for a conversion of an old application to an ASP.NET webapplication at beginning of the year. Generally, the development version of the webapp will also be the webapp that goes into production. We here make "clones" of the database server, assign new name, etc, which is then used for development, training, and so on without any threat of changing data on the real db (sql server 2005). I know it is possible to have more then one connection string in the web.config. My question centers around if there is a simple method for allow multiple connection strings and pick the one that is to be used for dev, production, training, and so on? I originally thought about constructing some type of admin form that the connection string can be selected from.
View 2 RepliesI have an app that is a bit old and will eventiall be rewritten but until I get the time it needs to continue to be patched. THe app is desgined broken into three layers (Web, DAL, BLL) The web site uses the DAL.DLL and BLL.DLL and the Website has some dataaccess and the sonnection string is saved in the web.config. For the DAL it is stored in the app.settings. Is there a way for the DAL to use the connection string that is stored in the Web.config even thought it is in DLL for the production site?
View 2 RepliesI was reading about how it is a good idea to encrypt the connection strings for security purposes. I came up with a solution that I think may be somewhat elegant, but there may be big flaws in my thinking. I am overworked and tired :)
Basically I have a setting in the web config EncryptConnectionString. In the Global.asax. Application_Start I am checking this in the config. If it is true, I am encrypting the connection strings. If it is false, I am decrypting the connection string.
Question #1 Is there a better way?
I finished my first asp mvc project and want to post it to a iis7/sql2008 server.I published the site just fine and migrated the sqlexpress database to sql2008 with no problems.However, when I run the program it still connects tp sqlexpress and opens a user instance.For the life of me I cannot get the connection string correct:
The current sring is:
<add name="AlertEntities" connectionString="metadata=res://*/Models.Alert.csdl|res://*/Models.Alert.ssdl|res://*/Models.Alert.msl;provider=System.Data.SqlClient;provider connection string="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Alert.mdf;Integrated
Security=True;User Instance=True;MultipleActiveResultSets=True"" providerName="System.Data.EntityClient" />
</connectionStrings>
How do I change this to make it see the sql2008 database?
Does anyone has an idea on how to change the connection string of the webparts at runtime. i have a multitenant app, and would like to store each accounts users settings in their respective DB's i tried changing the connstring in the webpartsmanager init, and the page load event
