How can connect to host's db from host? - c#

I bought a Windows hosting from GoDaddy. I have configured the configuration settings(Adding database and publishing project's files to host)
I can access the database while running the project on the local server.
But when I transfer the project to the server, the project on the server can't do it.
I wrote my connection string to web.config file, here it is:
<add name="xyz" connectionString="Data Source=IP ADDRESS;Initial Catalog=DBNAME;User ID=USERNAME;Password=PASS;Integrated Security=False" providerName="System.Data.SqlClient" />
I used MVC and Entity Framework, I also used layered structure
Thank You.

try to check more details about the connection string that should be used with your database provider. Here you can find several examples about how to create your connection string properly in SQL SERVER.
please notice that if you are working in your host machine, you have not to specify the IP ADDRES of your SQL SERVER but the SERVER NAME just like:
Data Source=(SERVER_NAME) \ DB_INSTANCE_NAME
I hope that it's gonna be useful.

Is There a Connection String For Connecting to Client Machine

I installed a windows form application on a client computer but when I try to log into my application it gives me this error:
a connection was successfully established with the server, but then an error occurred during the login process. (provider: shared memory provider, error: 0- No process is on the other end of the pipe.)
This is a c# windows form application running with SQL Server database, with login details. I have added the in and out bound rule on my firewall, I have tried changing my connection string severally, I have enabled tcp/ip port with its default port number, I have tried using the same network for both computers, I have tried using window and sql authentication, I have disabled firewall on client computer
Here is my connection string
<add name="connstrng" connectionString="Data Source=(local);Initial Catalog=AnyStore;Integrated Security=True"/>
I expect to be logged in to my application on the client computer using the same database with my server computer.
Connection strings are usually defined within the Web.config file. As #Panagiotis Kanavos said, the string is connecting to a local data source, which should work as expected within your dev environment. The web.config file should be located within the root directory of your project. Edit this file on the client's machine to point to the expected server / database. You may want to keep a blank or default version of this file in source control to avoid overwriting other's connection string info.
Example String:
<add name="SomeDB" connectionString="Data Source=snapdragon\SQL2k14;database=DBNAME;User Id=username; password=password" providerName="System.Data.SqlClient" />
Edit: "snapdragon" would be the host computer name. "SQL2k14" would be your sql server instance.
ok, i found the solution i changed my connection string and its working fine now, thanks guys.
here is my connection string-
<connectionStrings>
<add name="connstrng" connectionString="Data Source=DESKTOP-5I8TFY3\EMEKA;Initial Catalog=AnyStore;User ID=adminpos;Password=********" />
</connectionStrings>
</configuration>

Publishing WPF application with a LINQ to class database

I have a WPF application holding a LINQ to class database, now I need to publish this application to work on client's machine.
I have done this but it doesn't work like if the database was not found, I think my problem is that the database is not included in the deployed files, so I need help with a clear steps to publish my application including my database.
Thanks in advance
It's not possible to interact with your .mdf database without having SQL Server engine installed on your client machine .
Try this:
Install SQL server Express on your Client machine
Attach database to the SQL Server (using .mdf or using a DB backup)
then change your connection string before deploying the application in client machine.
if you've hard coded the connection string then , you'll have to change the connection string to adjust client's machine name , or add you connection string inside app.config in order to give you the flexibly to modify it after deployment .
App.Config:
<configuration>
<connectionStrings>
<add name="Test" connectionString="Data Source=.;Initial Catalog=OmidPayamak;IntegratedSecurity=True" providerName="System.Data.SqlClient" />
</connectionStrings>
using
var connection = ConnectionFactory.GetConnection(ConfigurationManager.ConnectionStrings["Test"].ConnectionString, DataBaseProvider);
wish it help .

C# Linq-to-sql server name when creating a release

I'm working on C# linq-to-sql application over SQL Server express 2008 . My database is inside SQL server.
I'm using Windows Authentication to connect to sql server from my application.
The server name used in connection string is related to my pc user name, so I'm wondering if I create a release of my application and put it on client pc which have SQL Server installed with another server name, would my application work?
my connection string is
<add name="WindowsFormsApplication1.Properties.Settings.OPTICA_MDFConnectionString"
connectionString="Data Source=ENG-MEDIAN-PC;Initial Catalog=OPTICA.MDF;Integrated Security=True"
providerName="System.Data.SqlClient" />
Because the app and the sql server are on the same host you can use "Data Source=.\<instance name>" which may be the default MSSQL.
That default would look like this:
connectionString="Data Source=.\MSSQL; ... "
For another example, our developer boxes' app.config uses this:
connectionString=".\DEVSQL;Initial Catalog=..."
Note that the "." is the host and that "DEVSQL" is the sql server instance name.

How to connect to SQL Server from a client machine?

Hello everybody i have a question and confusion about a project that i developed, and I will be very happy if you help me to improve my project.
I worked in VS2010 with C# and my database is attached in Sql Server 2008. my app is supposed to work in a LAN, so i'm thinking to make two versions of this app, the first will include the database and the sql server(plus the winforms of course), the second will just contain dotNet framework and it's supposed to connect to the database installed on the other machine. Is it possible. If so, how??
yes it is posible.
alter your connection string's "data source" to "ip address of the server"
Suppose in your machine where sql server is installed you are using this connection string
"data source=localhost;initial catalog=databasename;uid=sa;pwd=password"
then in the client system you need to alter it like this
"data source=IpAddressOfTheServer;initial catalog=databasename;uid=sa;pwd=password"
Note: the application having server's ip address in connection string is accessible by both, server and the client.
if Connection String in your (c# ) code Setted, Change connection string's "Data Source" to "IP address of server"
an another way change connection string in (App Config or WebConfig) at StartUp Project by below format:
<configuration>
<connectionStrings>
<add name="DB" connectionString="Data Source=192.168.10.5;
Initial Catalog=SafetyDB;Persist Security Info=True;User ID=sa;
Password=a1234$; connection timeout=5000" />
</connectionStrings>
