My web application has to retrieve database from more then two difference sql server.
for example, one from localhost, one from different server ip.
all firewall setting was finished, but i just dont know how to code and use it.
here is my web.config :
[Code]....
this defines only one database in my localhost.but i need to call different connection strings each time i need.
how do i implement this?
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?
View 1 Repliesjust 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 have deploy my web site, it contains a project!
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)?
ps: for connect to DB I use not the c# code:
var db=from x in AccessDB.Example select x;
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.)
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
</configSections>
<connectionStrings>
<add name="NyStories.Properties.Settings.storyConnectionString"
connectionString="Data Source=|DataDirectory|story.sdf;Password=driver;Persist Security Info=True"
providerName="Microsoft.SqlServerCe.Client.3.5" />
</connectionStrings>
</configuration>
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 called the string in my Data layer
string connectionName = System.Configuration.ConfigurationSettings.AppSettings["Connection"].ToString();
now how could call it in SqlConnection con
We can store Connection String in Web.config file in two ways One is
<connectionStrings>
<clear/>
<add name="LocalSqlServer"
connectionString="Data Source=(local);Initial Catalog=aspnetdb;Integrated Security=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
Other One is
<appSettings>
<add key="ConnectionString"
value="server=localhost;database=Northwind;uid=sa;password=secret;" />
</appSettings>
Now I want to know What is difference between these two approach? Which one is better way? What are their limitations?
UPDATE:Can you explain that <connectionString> has any significant advantage over <appSetting>?
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.

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.

View 3 RepliesI want to encrypt the connection string in web.config, the problem is each time a developer changes the connection string in web.config and publishes, it needs to be encrypted every time in the web server. Is there any way that the connection string can encrypted automatically every time someone publishes it?
Note :- All of us work on our local machines other than the server. So encryption using local machine key is not an option.
I am having trouble connecting to a ms sql database on the server. The hosting company said that the .sql file was imported successfully, but when I try to use the 'login' or 'create account' features im getting an error page saying:
Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. make sure the user has a local user profile on the computer. The connection will be closed.
I am sure all the connection info is correct so it is really frustrating trying to work the problem. I have listed the connection string in my web.config file to see if anyone can see anything wrong with it.

When I doing unit testing, I suddenlt got error message like:
The test adapter ('Microsoft.VisualStudio.TestTools.TestTypes.Unit.UnitTestAdapter, Microsoft.VisualStudio.QualityTools.Tips.UnitTest.Adapter, Version=10.0.0.0, Culture=neutral, ublicKeyToken=b03f5f7f11d50a3a') required to execute this test could not be loaded. Check that the test adapter is installed properly. Operation is not valid due to the current state of the object.
I had this before, to resolve this is to set default run in my testrun.config. After that, I can run unit testings, but I got error :
System.NullReferenceException: Object reference not set to an instance of an object.
The problem is that unit testing cannot initiate DBConnection. Here is my DBconn.vb:
