title: Have to make a connection string for my C# Application with SQL Server database
body: <p>I have problem with my C# application with database connection on the client PC.</p>
  
  <p>I have developed an application for a small store which controlling from one computer my means it's not over LAN or WAN, it is just one computer database for my friend's shop.</p>
  
  <p>Now the problem is that the system is working fine in my PC but the connection is not working on my friend's PC.</p>
  
  <p>My connection string is:</p>
  
  <pre><code>SqlConnection con = new SqlConnection(@"Data Source=.;Integrated Security=SSPI;Initial Catalog=Store");
  </code></pre>
  
  <p>If there is any way to solve this problem?</p>
  
  <p>Are there any great tutorials to learn all C# and ASP.net? Thanks Dears.</p>
