Answer 1

You could use the SqlCommand.ExecuteNonQuery method to execute an insert statement against a database connection:
http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlcommand.executenonquery(v=vs.110).aspx
using (SqlConnection connection = new SqlConnection(
"your connection string to the database..."))
SqlCommand command = new SqlCommand("INSERT INTO [yourtable] (UserName, Password) VALUES (@UserName, @Password)", connection);
command.Parameters.AddWithValue("@UserName", txtUserName.Text);
command.Parameters.AddWithValue("@Password", txtPassword.Text);
command.Connection.Open();
command.ExecuteNonQuery();
You can retrieve the value of a TextBox, such as your Username and Password textBoxes, by its Text property (nameOfTextBox.Name).
You will also need to specify a valid connection string to your database:
http://www.connectionstrings.com/sql-server/
And of course you must also replace [yourtable] and "UserName" and "Password" with the real names of your database table and it columns in the sample SQL statement code above.
Hope that helps.
