private void button1_Click(object sender, EventArgs e) { Employee emp = new Employee(); EmployeeDetails ed= emp.GetEmployee(int.Parse(textBox1.Text)); label7.Text = ed.EmployeeID.ToString(); label8.Text = ed.FirstName; label9.Text = ed.LastName; label10.Text = ed.HomePhone; label11.Text = ed.Notes; } The Configure() method of the RemotingConfiguration class is called in the Load event handler of the form. This method is the same as the one we called in the console application. The code passes the full path of the client configuration file to the Configure() method. This call is needed just once and hence it has been put in the Load event and not in the Click event of the Show button. Inside the Click event handler of the Show button, a new instance of the Employee class is created. Then the GetEmployee() method of the Employee class is called by passing the supplied employee ID. The GetEmployee() method returns an object of type EmployeeDetails. The details such as EmployeeID, FirstName, LastName, HomePhone, and Notes are then displayed in labels.

The user can allow or deny this access, and also has the option of suppressing future requests. What s especially unusual about this set of APIs is that you can provide some custom text that will display as part of the permissions prompt. You do this by implementing the ReasonProvider method and invoking ApplicationPermissionsManager. addReasonProvider(), as shown in the next example.

y now, you are enjoying your Drupal site quite a bit. You can create many types of content, are attracting new users to your online community, have developed a gorgeous theme, and have installed a dozen contributed modules to add all sorts of great new features. Congratulations! Isn t Drupal fun You re not quite finished, though. Some aspects of Drupal won t work right without enabling automated tasks to run, and I haven t discussed some of Drupal s most interesting configuration options yet. For example, Drupal is capable of running any number of web sites from one installation. This is exceptionally useful after you ve made your first successful site and want to repeat your success. It also makes maintaining the code much easier, as there is only one set of scripts for all your sites. Somewhere in the back of your mind, you might be aware of the importance of making backups of your data, but what have you actually done to guarantee that you can recover from a server disaster If your backup and recovery plan leaves something to be desired, read on. This chapter guides you through a practical backup strategy that will save you much heartache and trouble if you ever need to restore your site. Upgrading your Drupal installation and testing new features can be a tricky business. Here, I ll give you practical advice and instructions on how to go about both of these tasks in a way that minimizes the risk of inadvertently breaking your production site. The final section in this chapter looks at how to find help on the Web and some of the resources available on Drupal.org. I then close this part of the book with some thoughts about the Drupal community and how the software that runs Drupal sites directly contributes to the unity and involvement of the people who use and develop Drupal.

Note You can also create the database via a CREATE DATABASE T-SQL statement. To do so, you can open a query window of SQL Server Management Studio by clicking the New Query toolbar button and then executing a CREATE DATABASE database statement. This will create a new database named Database with default settings.
