Provider Connection String Of Entity Framework Be Substituted With A DB Connection String Already Defined In Web.config?
Feb 2, 2011
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?
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?
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.
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?
just for my testing purpose i know i can define both the connection's outside in a single web config file by different name's and access them in my front end according to it but what if i want to have seprate for both connection's web.config situation is like this see image so i want to access my connections from second web config file how i can do that.
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.
I am using sql-server 2005.How can I build the connection string, and what is the database provider?Can I see that on Microsoft Sql Server management studio?
I added a database to my project. When I did so an app.config file was added to my project. (Yes I know I have dangerous info in the connection string. I shall change that but for now I am messing around with test stuff.)
I did a google search on how to get the connection string value and found. string sConn = ConfigurationSettings.AppSettings["ConnectionString"]; I am getting a warning that this is obsolete. It has been replaced by ConfigurationManager.AppSettings. Ok Fine. According to the docs, it is also in System.Confiuguration which I already have a using statement for above. But when I attempt to use it, it is not part of the assembly.
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.
On shared hosting with 123-reg.
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.
Exception Details: System.Configuration.Provider.ProviderException: 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 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 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 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.
I 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?
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 Membership configured with IIS7, tables for it located in my own database, created with aspnet_regsql utility, and I am using custom connection string to access it.
This is part of web.config related to Membership :
in MyWeb there are all the aspx page and some entites datamodel, in MyApp there are the class with function like "getter data from DB" and there is a entity data model.
afeter the deploy, I have only the web.config and the connection string for the entity datamodel....itīs run ok, read/write the data on the DB.
The problem is with MyApp.....after the deploy it is a dll file and I donīt have the app.config and the entity inside it donīt run, not read/write nothing on the DB.
There arenīt error or messager but not read/write the data in the MyApp project.
all run on the iis 7
now...the question is:
I lose the connection string (in app.config) after the deploy?
Can I put a entity in the MyWeb and read it in another project (myApp)?
