Installation :: Uniting All The Connection Strings In Linq To Sql?
Jun 14, 2010
I have a datalayer that uses Linq to SQL , inorder to maintain properly I removed various references to the connection strings to be placed in the same location.
So used the base(ConfigurationSettings.ConnectionString[""].ConnectionString,mappingsource) in the dbml.designer.cs file.
But doing this we have to define the connection strings in the web.config of all the projects that are going to use the data layer.. instead is there a way where in I can define the connection strings in the app.config of the data layer project and have the dbml.designer.cs file to pick from this one place?

i want define connectionSreing in the web.config and then use it for DataContext ConnectionString. i do that : 1. i creat a class in App_Code :(MisaghDB is my database)
partial class MisaghDataContext
{
partial void OnCreated()
{
this.Connection.ConnectionString =
ConfigurationManager.ConnectionStrings["MisaghDBConnectionString"].ConnectionString;
}
// or
public partial class MisaghDataContext
{
public MisaghDataContext() : base (ConfigurationManager.ConnectionStrings["MisaghDBConnectionString"].ConnectionString)
{
OnCreated();
}
}
}
2. Add the connection string to my web.config file:
<configuration>
<connectionStrings>
<add name="MisaghDBConnectionString" connectionString="Data Source=NAZLIN-HP;Initial Catalog=MisaghDB;Integrated Security=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
</configuration>
3. Right click on the DBML file design surface and chose properties. Select "none" for the Connection property.now should i change DBML file designer.cs (Misagh.designer.cs) ? The code should I delete in this file(DBMLfile designer.cs)? this is a part of my DBMLfile designer.cs :
[global::System.Data.Linq.Mapping.DatabaseAttribute(Name="MisaghDB")]
public partial class MisaghDataContext : System.Data.Linq.DataContext
{
private static System.Data.Linq.Mapping.MappingSource mappingSource = new AttributeMappingSource();
public NorthwindDataContext() :
base(global::WindowsFormsApplication2.Properties.Settings.Default.NorthwindConnectionString, mappingSource)
{
OnCreated();
}
public NorthwindDataContext(string connection) :
base(connection, mappingSource)
{
OnCreated();
}
public NorthwindDataContext(System.Data.IDbConnection connection) :
base(connection, mappingSource)
{
OnCreated();
}
public NorthwindDataContext(string connection, System.Data.Linq.Mapping.MappingSource mappingSource) :
base(connection, mappingSource)
{
OnCreated();
}
public NorthwindDataContext(System.Data.IDbConnection connection, System.Data.Linq.Mapping.MappingSource mappingSource) :
base(connection, mappingSource)
{
OnCreated();
}
............}

I have a C# web service where I need to access a MS SQL DB. I see a way of creating a connection string in IIS and using it in the web application when connecting to the DB. In IIS in Connection strings you specify the name of the connection, server, user n pwd How can I use the name of connection string created in IIS in my c# app.? I am currently using
CustomerInfo
customerinfo = new
CustomerInfo();
// to return
using
(SqlConnection
connection = new
SqlConnection("server=servername;
initial Catalog=eostartest; Integrated Security=SSPI"))
{...
But I would like to use the name of the connection string created in IIS Connection Strings manager. Do I have to add something in the web.config as well?

In IIS 7 you can create database connection strings. I suppose this must be encrypted and best protected by IIS. This is nice, but how do I access it programmatically?

I used the following command to encrypt my connection string but an error ocurred,
"The connection name'DatabaseConnectionString1' was not found in the applications configuration or the connection string is empty" How can I encrypt it while keeping the application working? What if I move the encrypted application to another computer? Will it work?

I'm trying to encrypt the connection strings in my web.config. I'm following:
http://msdn.microsoft.com/en-us/library/2w117ede.aspx
however when I get to the part with the command:
aspnet_regiis -pe "connectionStrings" -app "/MyApplication" -prov "MyProvider"
it keeps complaining:
"The configuration for the virtual path '/MyApplication' and site 'Default Web Site' cannot be opened
Failed to map the path '/myapplication'
Failed!
I'm fairly sure I've followed the instructions correctly. I created the project named 'MyApplication' directly in the 'C:' root.
Perhaps I should be following a different set of instructions?

I was asked to design a asp.net website with modular programming, yet I have no clue what that actually means, does he mean structured programming?, everything I've found on modular programming has no relation to an asp.net website (or its code behind). Could someone explain what it means if: I have a database connection on each page of the website rather than having the connection string in the global or webconfig page? Does this mean structured or modular? In what terms could you achieve modular programming with a website that has no loadable modules? Its just a site with a few connection strings and some clever programming to do some fancy html?
I've seen other posts about webparts and cms but really have no understanding of them? Are they relevant? Unsure. My site is just a social network site that allows some one to login/create account with the website then go to his own profile and display things about himself that are saved to our database. Nothing in it requires modules as far as I can tell? So it makes me think is it a different method of actually "programming" writing the code? i.e is it stored in a different manner is it refrenced in a different manner is called in a different manner?

I'm using the template posted in this thread to generate C# enums from a couple of lookup tables in SQL Server within a class library that contains my DAL.
At the moment, I have the connection string used by the templates embedded an a template include file in the class library. Is there a convenient way to have the template grab the connection string from the main project (WAP)'s web.config without having to include a physical path? Or is there a better way to approach this?
I've also considered creating a SQL CLR assembly which returns a table-valued function containing the enum contents (which would then be defined in C#, not in the database), but I'm not sure what the performance hit would be. Whether or not it's significant will obviously be application-dependent but I'd hate to charge down a crappy path if it's a know best-avoid-this approach.

On most of my asp.net web application I have at least 4 computers that I am constantly moving my application around to. My development PC at work, at home, a test web server for others to test then finally the production server. In all cases I am using a MS-SQL database that would be on a minimum of 3 (usually 4) different sql servers. I am constantly changing the connection string(s) in the web.config file. Now I have just learned about Entity Frameworks which apparently requires its own connection string.
As far as I know the only references to the connection string(s) would be the web.config settings for the asp.net membership and role provider settings and now the entity framework object. So I was hoping I could do some coding in the Global.asax unit under some function and "detect" which server I am running on maybe by its name or something that would be both constant and unique on all machines. Then programmatically configure the membership provoders and entity framework object to use the correct connection string.

This seems like a really silly question, but I've had a search around and I can't find anything about this. I've got a DB connection string that I'm creating in my web.config:-
[Code]....
and
[Code]....
but I need this connection to be read only. I've defined all my linq objects with only gets on their properties, and none of my (MVC) repository classes have .SubmitChanges() methods in them so I'm 99% sure the system can't update this DB, but I would also like to set my DB connection to be RO if at all possible. I realise that ideally this should be done at the SQL server end and the user should be made RO, but that (for various reasons, out of my control) can't be done, so I wanted to lock down my connection as the app mustn't write to the DB.
Is there a "readonly" parameter I can apply to the connection string so that it would throw an error or discard the data if any updates were attempted?

I have just deployed my entire website onto my hosting provider. My databases worked fine whilst I was testing the website on the local host. They use Plesk Control Panel. Here is my connection string:
Data Source=.SQLEXPRESS;AttachDbFilename|DataDirectory|ASPNETDB.MDF";Integrated Security=True;User Instance=True (nothing is omited from this string)
Why isn't this working when the website is online? I get the error Invalid value for key 'attachdbfilename'. I have retargeted my website for .net 2.0 at the providers request because they do not support .net 4.

I have an ASP.NET project which is pretty n-tier, by namespace, but I need to separate into three projects: Data Layer, Middle Tier and Front End.
I am doing this because...
A) It seems the right thing to do, and
B) I am having all sorts of problems running unit tests for ASP.NET hosted assemblies.
Anyway, my question is, where do you keep your config info?
Right now, for example, my middle tier classes (which uses Linq to SQL) automatically pull their connection string information from the web.config when instantiating a new data context.
If my data layer is in another project can/should it be using the web.config for configuration info?
If so, how will a unit test, (typically in a separate assembly) provide soch configuration info?

I have two connection strings (both in Web.Config: CS_Local and CS_Production) for my DBML (Linq to SQL). In my Global.Asax/Application_Start I run some production preparation methods if the request is non-local (!HttpContext.Current.Request.IsLocal). Within that part, I'd also like to change the current connection string used by my DBML from the standard CS_Local to CS_Production.

I want to apply some better security measures to an existing web application. Currently, my connection string contains the user name and password in plain text. I'm also using a custom membership provider, which stores user names and passwords in the web.config file as plain text [URL] I would like to secure this information using an algorithm such as SHA1.
