I connected my database as a (sql server database file) to mt c# .net application.
the connection string was given as a relative path. the client computer asks for sql express server, what should i do? which application should i install in the client pc?
You need to supply the correct connection string, with the database server name.
If the application is supposed to connect to a local database (on the same machine as the application), you need to install SQL Express and setup the database on the client machine.

I have created a CRUD application that is running really well. It connects to SQL on the same machine. I want to publish my C# app and install it on another PC does not have SQL.
Is it possible to run it on that PC, without installing SQL Server on it? If so, how do I do this?
Is it possible to run it on that PC?
Without a database your application is "dead".
You have two options.
Install a sql server it this PC.
Connect to a sql server isntalled in another PC.
It's your choice.
If your project is a small one and the database is less than 4GB and you are not going to install SQL Server on every machine and your client do not have access to a Server with SQL Server then you may want to use SQL Server compact
In this case your database would be an single sdf file and you will connect to it using its path on the machine. Then the connection string would be like this:
Data Source=MyData.sdf;Max Database Size=256;Persist Security Info=False;
For more on connection string see this.

I am working on a Windows Forms application written in C#, and using Entity Framework 6 to connect to a SQL Server database, currently on the same local computer -- which I will be separating on another computer on production of course.
Now, would I need to alter anything before building the release? Or would the program find the database automatically when connected on the same local network?
You can connect to remote SQL by changing connection string from App.Config.
You can use server name : IP\SqlExpress, 5012.
Here IP is your public IP where DB is setup and 5012 is random port.
I am creating a window application with a SQL server database. The application need to be installed on a terminal server and other client machine should works with this application.
I have installed this application and SQL Server Express 2008 on server and application worked currently on server but not on client. I got an error on client machine through my application over connecting to the database on server.
Any help is appreciated.
The default installation of SQL Server Express is to allow only local connection.

My application contains a SQL Server 2008 R2 database.
If I want to install the application on some client's machine, do I need to install the SQL Server 2008 R2 database as well?
Or is there any shortcut to access to database without installation?
You do not have to install sql server on every machine that you want to run your client on, but it has to be installed in at least one place, and each client has to be able to access one sql server, possibly via the internet.
I am creating a window application that need to use sql server database.
I want to install this application to client machine without installing sql server so that my application can still connect to a database i.e mdf file that i will be providing at client system.
How can i connect to a database(mdf) on client machine through my window application without installing sql server. ?
I dont know is it possible or not.
If possible what will be the connection string in that case. Database need not be used in network.
Client mahine dont need any installation. Every thing needs to be run through pen drive
.mdf files are SQL Server database files. No other application can understand, read or update those files. If you need to open and mdf, you need a SQL instance. That instance can be local, can be an Express edition, or can be a remote one, doesn't matter. If your application needs a local SQL instance for it's own use then it can install SQL Server Express Edition when deployed.
You can try Sql Compact Edition or SqlLite. I think these are just a file based solution.
In that case you must have a server machine where your database files are stored. For that reason you have to use SQL Express Edition 2005 or 2008 in one machine and SQL server management studio to manage your database. Those are all free from Microsoft. The client machines will be connected through the connection string. Those machines don't need SQL instance or SQL server installed.

You can search your MS-VS CD for SQLEXPRESS (please note the capital letters) and include it in your software when you create the set-up and your problem will be solved.
You don't have any other way except to use another database like access.
This database doesn't need its software.
