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 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?
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.
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?
But ofcourse it is not working as I want to. The Ordering works on Question.Order, but I would also the Questions.SubQuestions List to be ordered according to SubQuestions.Order
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?
I'm Using Entity Framework in my ASP.NET Web Application and I added Procedure tom my Model and Create Function for it which will return ObjectResult ... i want to add Include Keyword to that object Result ... so how can i get childs for that object result
I want to write a query in Entity Framework that has multiple joins. The only problem is the tables arn't related using their primary / foreign keys (its the Umbraco database), as such I can't use .Include and the Navigation properties.
Essentially the query I would like to run is this:
select t.*, n.* from cmsContentType t inner join cmsContentTypeAllowedContentType a on t.nodeId = a.Id inner join vicinity.DocumentTypeExtendedProperty x on x.UmbracoDocumentTypeId = t.pk inner join umbracoNode n on n.id = t.nodeId
I have two EF entities mapped to cmsContentType and umbracoNode as such I would like them to be populated as if I was running the query like
var q = from p in cmsContentType.Include("umbracoNode")
In an MVC view, I'm looking for a way to determine if a parent entity's collection of child entities is empty, so I can decide if I need to call a RenderPartial() or not.
For a one-to-one I've been using the following:
<% if (Model.Book.GenreReference.EntityKey != null) %> {.....}
but I'm unsure how to do it in a one-to-many scenario, or if it can even be done without the use of Include() or Load().
I'm working with Visual Studio 2010 and for Data Connections am connecting to a SQL Server 2000 production database. When I try to drag a table to a .dbml file, the Object Relational Designer says, "The selected object(s) use an unsupported data provider." If I try to create an .edmx file via Generate from database, then the alert is, "This server version is not supported. You must have Microsoft SQL Server 2005 or later."
So VS 2010 has no support for the Data Entity Framework or LINQ when connecting to a SQL Server 2000 database? If that is the case, what is the best data access strategy for this scenario?
I have a question about Entity Framework. answer if you know answer on this. I have such query :
[Code]....
Particularly I want to join few tables in one query, but I can NOT use LINQ and can NOT use ObjectQuery with objects mapped to DB fields inside my query. Because each entity creates dynamically. So this is what i
can NOT use : [URL]
The question is can I use something like this instead of using objects?
[Code]....
The purpose is to use Join method of ObjectQuery with syntax as in Where method :[URL]
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
We're migrating one of our sites to ASP.Net. We do not want to use integrated security, which uses the windows account to connect to sql server (not going to get into why, its just out of the question). We created a username and password to connect to SQL Server, and would like to use that username and password, however, we also do not want other developers to see this information (easily read from the web.config).... I know it can be encrypted, but it can just as easily be decrypted by the developers - plus encryption has a performance hit.
I'm writing an ASP.Net MVC intranet application which is accessed via handhelds and a range of browsers. My users all have AD accounts and have different permission to our SQL database views/procs depending on who they area. The database also uses CURRENT_USER for horizontal partitioning.
Because of the range of devices that need to access the application I can't rely on impersonation/delegation or the trusted subsystem. I want the user to simply input username and password (same as AD) when the above mechanisms fail.
Does anyone know how I can use AD username and password in a connection string to access the database without creating a set of SQL mirror accounts? I can't login with network service or a sql proxy account because the database needs to be user aware.
I am connecting to Oracle database from .net using OLEDB.
My Connection string :
[Code]....
I am using above ConnectionString to communicate with database. To make it work, I have to store password (don't want to do that) in session and use it every time I need to talk to db.
1) Is there any other connection string without username and password with oledb?
2) I use "Integrated Security" for MSSQL. How can I use the same with OLEDB - Oracle database?
In the web.config, how do add a connection string by using a window authentication with the username and password? I have tried like this and it keeps ignoring the username and password
So it compiles, unfortunately when I run my app, it get this:
Parser Error Message: Could not create Windows user token from the credentials specified in the config file. Error from the operating system 'Logon failure: unknown user name or bad password.
Is there a way to export a EF 4.0 Data Model to EF 3.5?
I looked around and found that we are not able to access EF 4.0 from a ASP.Net 3.5 project here: [URL]
Our project is the 1st to go to .Net 4.0 using Entity Framework and we (the team) were wondering if there was a way for the other projects that "might" need to access our data that are still using the .Net 3.5 framework.
I need to be able to navigate through the file system from an asp.net page and gather metadata on files, directories ... The simple code I've put together makes a list of directories/files in a given location and has everything displayed as a link button. My problem is with link buttons under which I have paths that include ampersands and blanks. Here's a sample of code:
[Code]....
The Response.Redirect("aPage.aspx?d="+ e.CommandArgument.ToString()); line has the problem ... the e.CommandArgument.ToString() shows a truncated path that stops just before the first ampersand detected. I tried escaping the ampersand with a backslash but it did not work ... somehow I guess it's not exactly the character that's causing the problem ..
I am new to entity framework , it is really very good , but I want to know what is the difference between using entity framework with stored procedure or without stored procedure , which one the faster and what is the benefits for using stored procedures with entity framework.
I have an EDM, it includes the entities extension and history. My goal is to use history to keep track of all the changes made to extension entity. For example, if extension with ID 223 has its property 'Name_Display' changed - I want the history entity to record this.
I'm using ASP.NET with VB.NET. Where in my code do I put the hook to say, "update the history entity" and what should that hook look like?
