Today, my .NET has been reloaded. I got a .NET source code from the Internet, then imported the database, connect with the SA, but when I want to run a project Equipment, I can't connect. The database is. Cause: SA can only have a default database in SQL Server login properties
Changed it is possible.
From this matter, I learned a gradual analysis method and started thinking. Net has a problem, because in accordance with the installation file prompt to download the source code, I have to rewrite the .dll dynamic link library, I think I have an improper operation, change the .NET system file, then I will run the new project and run, just With SA unable to connect the database, this will find the source of the problem.
