Why does my connection string not work? - sql-server-2012

I want to upload my website. I uploaded my database's backup file and the connection string that the host give me is:
Provider=sqloledb;Data Source=127.0.0.1;User Id=sama;Password=****;
and I set the connection string in the web.config file like this:
<connectionStrings>
<add name="MyDBContext"
connectionString="Data Source=127.0.0.1;User Id=sama;Password=****;Initial Catalog=sama;"
providerName="sqloledb" />
</connectionStrings>
but my website doesn't work!
I use Entity Framework code-first model in my project.
Where is my problem??
Thanks.

Try something like this...
<connectionStrings>
<add name="MyDBContext"
providerName="System.Data.SqlClient"
connectionString="Server=127.0.0.1;Database=sama;User Id=sama;Password=****;"/>
</connectionStrings>

Database shows up in App_Data & not in SQL Server

Does anyone know why my database won't show up in SQL Server, but will show up in App_Data? I did code first migration and update the database but still can't see it. Please help
I try changing the connection and it did not work
<connectionStrings>
<add name="DefaultConnection"
connectionString="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\aspnet-Rentals.mdf;Initial Catalog=aspnet-Rentals;Integrated Security=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
No database shows up

Read Entity Framework 6 Connection String from appsettings.json file in ASP.NET CORE

I have a app.config xml file to save entity framework's connection strings as the following example:
<configuration>
<connectionStrings>
<add name="MyEntities" connectionString="metadata=res://*/EntityFramework.MyEntities.csdl|res://*/EntityFramework.MyEntities.ssdl|res://*/EntityFramework.MyEntities.msl;provider=System.Data.SqlClient;provider connection string="data source=myserver;initial catalog=Example;persist security info=True;user id=myId;password=myPassword;multipleactiveresultsets=false;application name=EntityFramework"" providerName="System.Data.EntityClient" />
</connectionStrings>
</configuration>
But I'm using ASP.NET Core, I manage multiple servers with an enviroment variable. so I need to save this connection string in my appsettings.{enviroment}.json, read this connection and set to the property entity framework context.
I think you are looking for something like the following construction.
"ConnectionStrings": {
"MyEntities": "metadata=res://*/EntityFramework.MyEntities.csdl|res://*/EntityFramework.MyEntities.ssdl|res://*/EntityFramework.MyEntities.msl;provider=System.Data.SqlClient;provider connection string="data source=myserver;initial catalog=Example;persist security info=True;user id=myId;password=myPassword;multipleactiveresultsets=false;application name=EntityFramework"
}
Not sure if this is the correct way to do this, but this may be a good starting point for you. I've added the configuration settings into the file named app.config. It appears that the contents in the files are written into the exe's config file. When the exe is executed the config settings are also loaded. I have just starting experimenting with .NET Core, so this may not be the recommended or correct way.
<configuration>
<runtime>
<gcServer enabled="true"/>
</runtime>
<connectionStrings>
<add name="TestName" connectionString="data source=MyServer;initial catalog=MyDatabase;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework" providerName="System.Data.SqlClient"/>
</connectionStrings>
</configuration>

Sql connection string for another pc

I have an application that runs on SQL 2005 database
I m trying to use same application on another machine same network,
I managed to log in on SQL 2005 using IP
Now I need to configure applications app.config file (found in visual studio solution) to allow connection
soo far I tried this connection string which isn't worked
this is what my config file looks like
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="ConnectionString" value="Data Source=ipaddress,1433;Initial Catalog=sample;User ID=sample;Password=sample;Trusted_Connection=True;" />
</appSettings>
</configuration>
Any help would be appreciated
Add this to your config file. Rather then using an appSetting use the actual connectionStrings section.
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=00.000.0.00,1433;Initial Catalog=taxi;Persist Security Info=True;User ID=sample;Password=sample; providerName="System.Data.SqlClient" />
</connectionStrings>
This string should work if anyone else got the same problem
thanks everyone for looking and trying to figure it out with me
<add key="ConnectionString" value="Data Source=00.00.000.000;Initial Catalog=sample;User ID=sample;Password=sample;" />

Retrieving default database connection string in code

I am working with the existing structures used by the dev team at my current company. In order to change connection strings within the application, the team creates an XML node called "defaultDatabase" (see below):
</configSections>
<dataConfiguration defaultDatabase="Development" />
<connectionStrings>
<add name="Development" connectionString="Data source=DVHQSQL01; Initial Catalog=db; User ID=id; Password=password"/>
</connectionStrings>
...there will be more connection strings in the XML for different server environments (not shown here, but "Testing", "Staging", "Production", etc)
I am creating a class with different functions that use the default connection. I know one route is through ConfigurationManager as shown here:
https://social.msdn.microsoft.com/Forums/en-US/9a8c9f5a-092e-4c4a-87bb-9f35d8f55da1/get-connection-string-from-appconfig-file?forum=adodotnetdataproviders
This is great if you can change the connection string name in code, but we use the defaultDatabase node to be able to change from different environments without rebuilding.
Does anyone have experience with this methodology? How do I get the correct connection string using the defaultDatabase node?
Just set the default connection in the connection strings area:
<connectionStrings>
<add name="default" connectionString="..."/>
</connectionStrings>
If you have further connections you can add them in the same way:
<connectionStrings>
<add name="default" connectionString="..."/>
<add name="special1" connectionString="..."/>
<add name="special2" connectionString="..."/>
</connectionStrings>
You can have as many connectionStrings as you want in your config, all you have to do is give them different names.
<connectionStrings>
<add name="default" connectionString=""/>
<add name="anotherOne" connectionString=""/>
...
</connectionStrings>

Failed login for user

I'm developing a website for sharepoint using asp.net, it is connected to a database. In visual studio server explorer, the database is accessible using a new sql user I created. I granted sysadmin permissions to that user. However, when I deploy the site and run it, it gives me this error 'login failed for user'.
The sql server is configured to allow mixed authentications. I restarted the server, I played with the user permissions but nothing ever changed.
The connection string I got it from server explorer which I'm sure it is correct:
Data Source=servertest;Initial Catalog=qDB;User ID=me2;Password=***********"
What should I do? I've tried every possible solution I found on google and I ended up here.
Try like this by editing your connection string:-
Server=myServerAddress;Database=myDataBase;User Id=myUsername; Password=myPassword;
I too had same scenario this worked for me
<connectionStrings>
<add name="connectionstring" connectionString="Data Source=XYZ\SHAREPOINT;Initial Catalog=DBName;Integrated Security=true;" providerName="System.Data.SqlClient" />
</connectionStrings>
You can Use connection string like this
<appSettings>
<add key="KhadamatConnectionString"
value="Server=[copy name from Your ServerName of SSMS];Database=AcaService;uid=admin;pwd=mypass;" />
</appSettings>
or
<connectionStrings>
<add name="KhadamatConnectionString" connectionString="Data Source=[copy name from Your ServerName of SSMS];Initial Catalog=AcaService;User ID=admin;Password=mypass;" providerName="System.Data.SqlClient"/>
</connectionStrings>
