Question

Hello I just publish an app that require a database with Sql Server 2008 and Visual C# 2010. It works really well on my laptop but when I try it on another laptop I got this error !

I use SQL Authentication method to grant user to read and write to the database but it is useless, this is my connection string

stringkoneksi = @"Server = .\SQLEXPRESS;" +
                        "Database = UGsimplify;" + 
                        "Integrated Security = false;" +
                        "User ID = 'userdefined';" +
                        "Password = 'blablabla'";

do you have any step by step to make it works on another laptop?

Answer 1

Try this:

stringkoneksi =   @"Data Source=myServerAddress\SQLEXPRESS;Initial Catalog=UGsimplify;User Id=myUsername;Password=myPassword";

Configure your SQL server security as sql server and windows authentication mode.

To set up SQL Server and Widows Authentication Mode.

1. Connect to you SQL Server Instance
2. Right Click the go to properties
3. Choose Security on Select a Page Container
4. Then Choose SQL Server and Widows Authentication Mode on Server Authentication.
5. Click OK

Make sure your laptop(Server) SQL Server instance is running.
