ASP.NET VB change db connection on web forms framework - asp.net

I have created an instance of ASP.NET Web Forms in my Microsoft Visual Studio. By default the program generates user login page and registration which are linked to the .mdb file.
I want to reconfigure the standard connection and link it to my instance of MSSQL 2012 SQLExpress server.
How can I do it?

Ok so I will give some direction and link you to a page.
First let me ask you this the connection you are using presently is it in a web.config file. If so this is where you will change the server/instance and database/catalog name.
Web.Config modification for SQL Server Instance
or this link
Web Config modification for SQL Express 2
So if you in the web.config file you should see something similar to this.
<ConnectionStrings>
<add name="" connectionString="Server=(localhost)\SqlExpress;Max Pool Size=300;Initial Catalog=database;User ID=username;Password=password;" providerName="System.Data.SqlClient"/>
</Connectionstrings>
or
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source= (LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\database.mdf;Initial Catalog=database;Integrated Security=True" providerName="System.Data.SqlClient" />
you need to change the follow:
Server or Data Source
and
Initial Catalog or AttachDbFilename
Now your credentials you may use any username and password that has access to the sql server express instance.
I hope this helps.

how to find the sql connection string in asp.net

I added a new Sql Server Database to my project with the name: ShDB.mdf. It is located in a App_Data folder.
It contains a Table which has some columns. I could add some numbers to the table and then show them in a gridview on my localhost.
This is what I have in the web.config:
`<configuration>
<connectionStrings>
<add name="ShConnectionStr" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Users\Javad\Desktop\Sharj\App_Data\ShDB.mdf;Integrated Security=True;User Instance=True"/>
<add name="ConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\ShDB.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
</connectionStrings>
<system.web>
<compilation debug="true" strict="false" explicit="true" targetFramework="4.0"/>
</system.web>
`
Here is the vb.net code which I used:
Dim connectionString As String = ConfigurationManager.ConnectionStrings("ShConnectionStr").ConnectionString
And it works properly on the localhost test but when I published the website and uploaded the files on a web hosting service to test, I counter an error. How may I fix it? I think I should change my Data source path but I don't know how because its my first experience. Thanks to any help. you can see the error page here: http://www.kaj.somee.com/SL.aspx
Sql Server is either not installed or not running on the web host, or you don't have access to connect to it.
ASP.Net does not by itself know how to use your *.mdf database. It needs a running instance of Sql Server to talk to. It will tell Sql Server to load (attach) your database file, and then send queries to the Sql Server service for execution.
Do you mean you already uploaded the website to a web hosting service, but not the database?
If so, your application may not communicate directly with your database which is actually in your local machine.
You probably need to upload the database to a database hosting service as well (eg.SQL Azure, etc).
You may need to figure out the IP address/Server Name of your database hosting where you have uploaded. These information you can probably get in for the service provider. From there you should be able to connect to the database with the correct configuration.

Deployment of SQL Server Express database fails

I have to deploy ASP.Net application with remote database connection in IIS server.
Deployment has worked fine without database. And I was able to run that application on the IIS server.
Coming to the application with remote database I have given the connection string in C# code. And it is connected.
My web.config has thsi connection string :
<configuration>
<connectionStrings>
<add name="ApplicationServices"
connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnetdb.mdf;User Instance=true"
providerName="System.Data.SqlClient" />
</connectionStrings>
I have replaced that with my database connection credentials as follows:
<configuration>
<connectionStrings>
<add name="ApplicationServices"
connectionString="Data Source=RemoteHost,1433;Initial Catalog=DBNAME;user Id=MyUserId;Password=MyPassword"
providerName="System.Data.SqlClient" />
</connectionStrings>
In Package/Publish options I have selected (Import from web.config) and deployed that. Then I got the following error:
Web deployment task failed.(Object of type 'dbFullSql' and path 'Data
"Data Source=RemoteHost,1433;Initial Catalog=DBNAME;user
Id=MyUserId;Password=MyPassword" cannot be created.)
Object of type 'dbFullSql' and path "Data Source=RemoteHost,1433;Initial Catalog=DBNAME;user
Id=MyUserId;Password=MyPassword" cannot be created.
The source is invalid.
Script failed for Database 'DBNAME'.
Script failed for Database 'DBNAME'.
Index was outside the bounds of the array.
I am new to ASP.Net. Anybody please help me.
Thank you in advance
I think you didn't configure Web deployment package correct you can do that right Click on Project ,Select Properties and go to package/Publish SQL
I have add link for Walkthrough: Deploying a Web Application Project Using a Web Deployment Package (Part 1 of 4) for VS2010

mvc4 authorisation doesn't work with ASP.net Configuration

I am following along this series:
http://www.asp.net/web-api/overview/creating-web-apis/using-web-api-with-entity-framework/using-web-api-with-entity-framework,-part-1
It all goes well up to the point, where one is requiered to use the ASP.net Configuration tool to create a role Administrator, a user and then log in.
[Authorize(Roles="Administrator")]
works fine, but I can't log in with the "Admin" account created via ASP.NET configuration; or, vice versa, see the users which I registered in the demo on the ASP.NET configuration panel.
And why did this demo create 2 Connectionstrings to two differend databases?
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-WebStore-20120820081613;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-WebStore-20120820081613.mdf" providerName="System.Data.SqlClient" />
<add name="OrdersContext" connectionString="Data Source=(localdb)\v11.0; Initial Catalog=OrdersContext-20120820083248; Integrated Security=True; MultipleActiveResultSets=True; AttachDbFilename=|DataDirectory|OrdersContext-20120820083248.mdf" providerName="System.Data.SqlClient" />
I'm running the whole thing on Windows Server 2008 R2; Visual Studio Express 12.
I've solved the issue by recreating the application with visual studio 2010.
... copied the connectionstring to the vs2010 project and voilá ... done.

asp.net| change the place webforms save user data

I am trying to change the place my webform saves the data.
What I mean is, when you open a Visual Stuido/C# Web App, its has a user login/register data.
The default data is saved in your project folder, in APP_DATA as: ASPNETDB.MDF.
What about if I want to use MSSQL Server 2008R2.
How can I change it?
Just setup a new database and change your connectionstring in the web.config:
Using SQL Server instead of ASPNETDB.mdf
<connectionStrings>
<add
name="NorthwindConnectionString"
connectionString="Data Source=serverName;Initial
Catalog=Northwind;Persist Security Info=True;User
ID=userName;Password=password"
providerName="System.Data.SqlClient"
/>
</connectionStrings>
How to: Read Connection Strings from the Web.config File
in really server MS Server 2008R2 you must doing backup from your "home" datafiles: "in APP_DATA as :ASPNETDB.MDF"
p.s. sorry for my bad English.

Whats wrong in this ASP.Net web.config connection string?

i have attached database file C324040_volvo.mdf to my mssql2005 management studio whose name in mssql2005 management studio is ASPNETDB
but page doesn't found the database....and the site doesn't load
i m testing my site in my local computer ...
<connectionStrings>
<add name="connectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=C:\C324040_volvo.mdf;Database=ASPNETDB;Integrated Security=True;User Instance=False"
providerName="System.Data.SqlClient" />
</connectionStrings>
Page searches for a log time ...
If you've already added it to SQL Server then you shouldn't need
AttachDbFilename=C:\C324040_volvo.mdf
If it isn't already attached, then SQL probably doesn't have rights to the root of C: and you should move it.
