Whether a particular side effect is stronger or weaker depends very much on your application and whether the consequences of the side effect are sufficiently isolated and separated from other entities. Strong side effects can and should be used freely in the outer shell of an application or when you re scripting with F# Interactive; otherwise, not much can be achieved. When you re writing larger pieces of code, you should write your application and libraries in such a way that most of your code either doesn t use strong side effects or at least makes it obvious when these side effects are being used. Threads and concurrency are commonly used to mediate problems associated with strong side effects; 14 covers these issues in more depth.

Using SQL Server Management Studio Express (SSMSE), you ll create a stored procedure that produces a list of the names of employees in the Northwind database. It requires no input and doesn t need to set a return value.

Use the following steps to create a Windows service project: 1. Click File New Project, or press Ctrl+Shift+N. 2. In the Project types pane of the New Project dialog box, select Visual C# Windows. 3. In the Templates pane, select Windows Service. 4. Give the application a name; I ve called the project Complaint. You may choose a different location for storing the application files according to your preference. 5. Let s add the Installer to the project by right-clicking the open area inside the service designer and selecting Add Installer (see Figure 8-3). Please make sure to use LocalSystem as the Account and Automatic as the StartType. 6. Click the OK button to finish the process. VS will create a new Windows service project with the name Complaint. Please add a new dataset to the project, and name it dsComplaint. Before continuing, please make sure your solution looks similar to Figure 8-9.

Some networks in offices require that you use a web proxy (often referred to as an HTTP proxy). A proxy is a server computer that provides additional security by providing a single portal to all web pages. It also helps speed up Internet access by storing frequently accessed pages. This means that if ten people request the same web page, there s no need to get the same ten pieces of data from the Internet. The proxy computer can send them its own copies. You ll need to speak to your system administrator to see if your office uses a proxy. If it does, your administrator will most likely give you an address, which may take the form of a web address (a URL) or an IP address. Once you have this information, follow these steps to configure the proxy:
