View 2 RepliesI 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.
I have this in the web config file <connectionstrings> section. Why is there an add and then remove and then again an add...what is it trying to accomplish here? and in the second code section, I use that string in a sqldatasource control. Second question: Can I just use the name attribute value "localsqlserver" form web config file, in place of the connection string in the data source? is it why that attribute is for?

View 5 RepliesI 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 RepliesI'm running into a really annoying problem with my Linq to SQL project. When I add everything in under the web project everything goes as expected and I can tell it to use my existing connection string stored in the web.config file and the Linq code pulls directly from the ConfigurationManager.
This all turns ugly once I move the code into its own project. I've created an app.config file, put the connection string in there as it was in the web.config but when I try to add another table in the IDE keeps forcing me to either hardcode the connection string or creates a Settings file and puts it in there, which then adds a new entry into the app.config file with a new name.
Is there a way keep my Linq code in its own project yet still refer back to my config file without the IDE continuously hardcoding the connection string or creating the Settings file? I'm converting part of my DAL over to use Linq to SQL so I'd like to use the existing connection string that our old code is using as well as keep the value in a common location, and one spot, instead of in a number of spots.
Manually changing the mode to WebSettings instead of AppSettings works untill I try to add a new table, then it goes back to hardcoding the value or recreating the Settings file. I also tried to switch the project type to be a web project and then rename my app.config to web.config and then everything works as I'd like it to. I'm just not sure if there are any downfalls to keeping this as a web project since it really isn't one. The project only contains the Linq to SQL code and an implementation of my repository classes.
My project layout looks like this
[code]....
Every time I try to make the default constructor look like the first way, it always auto changes back to the second way once I make a change to the file unless the DBML is inside of a web project.
I will explain the my current yet simple architecture of my application(s). At the moment I have my main web application as a separate project. I then reference the CoreBLLDAL (Business Logic and Data Access) Project so that several projects can have access to the BLL/DAL Project.
Within the CoreBLLDLL Project I use TableAdapters for my DAL.
I have just upgraded to VS2010 and I would like to make use of the Config Transforms, allowing me to have a separate web.config for test and production - however, TableAdapter get the connection string from the Settings.settings file.
How can I change the TableAdapters to get the connection string from the app/web.config file? I read that you can change this within the designer file for the TableAdapters by using ConfigurationManager, however, I tried this but I do not have access to the ConfigurationManager namespace. I presume this is because the project is a class library and not a web application - I am not too sure.

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 have a query which gets values from two tables which are in different databases.How can I write a SINGLE Connection String which connects to two databases? By the way I am using SQL Server Database
View 7 RepliesI 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.
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 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.

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?
