Two questions:
1. How can I execute a SQL statement in a windows project (the database i attached to the project).
and
2. How do I make windows MDI children of an MDI main form?

I don't know exactly what it means to "attach" a database to a project, but the idiom is to establish a connection to the db and then build up and execute your query, and then process the result set. I believe Microsoft offers ADO for that sort of thing.

You should really use entities framework or Linq to SQL if you develop for .net 3.5 (and maybe WPF while you're at it).

If not, I believe there is a designer where you can input SQL and execute it.
It's been a long time since I made windows forms and ado.net projects though.

in order to execute SQL statements you need to use one of two things.

you either need to use a reference to a .dll file for databases such as MySQL or something similar, or you can use MS's builtin ADO statements.

ADO is very easy to use. i have also used the MySQL extension and that is very easy as well. you just need to have the MySQL service running.

_Login = new LogIn();
            _Login.MdiParent = this;
            _Login.WindowState = FormWindowState.Maximized;
            _Login.UserLogIn += this.LogUserIn;
  if (ActiveMdiChild != _LuaFinder)
            {
                if (ActiveMdiChild != null)
                {
                    ActiveMdiChild.Hide();
                }
                _LuaFinder.Show();
            }

I think is something close to what you are looking for the midi stuff. Thats with 3.5, and I don't know how different it is in the older frameworks (and I don't know if what I am doing is "correct", but it works).

Also if you are using 3.5, open up google and look up LINQ, do not pass go, do not collect $200. When you generate your DataContext object it should auto create the connection string for you.
