So what is managed code, then Managed code is code that provides enough information to allow the common language runtime to perform the following tasks: Given an address inside the code, locate the metadata describing the method Walk the stack Handle exceptions Store and retrieve security information For the runtime to carry out these tasks, the code must pass a verification process unless a network administrator has established a policy that allows code to run without verification During the verification process, the JIT compiler examines the MSIL code and the metadata to determine whether the code can be classified as type-safe Typesafe code is code that can be determined to access only memory locations that it owns This restriction ensures that the code works and plays well with other programs and that the code is safe from causing accidental or malicious corruption.

In this exercise, you create a webpage that allows the user to generate a list of names, select a shipping type, and select multiple destinations.

5. On the Merging Profile Information page, click Next. 6. On the VPN Support page, select the Phone Book From This Profile check box. In VPN Server Name Or IP Address, click Always Use The Same VPN Server, and type 10.0.0.2, and click Next.

Open Visual Studio and create a new website called WebserverControls. Create a new page without a master page and edit it in Design view. Drag a Label to the page, and set the Text property to name:. To its right, drag a TextBox control, and set the ID property to nameTextbox. To its right, drag a Button control, set the Text property to Add, and set the ID property to Addbutton.

On the next line, drag a Literal control to the page, and set the Text value to shipping Type:. Below that, drag a RadioButtonList control to the page. Add three items, with the Text properties set to standard, Priority, and Urgent. (To create a new line in the Visual Studio designer, simply place the cursor after the last control and press the Enter key.) Set the ID value to shippingTypeRadiobuttonList. On the next line, drag a Literal control to the page, set the Text value to Destinations, and set the ID value to DestinationsLiteral. Below that, drag a CheckBoxList control to the page, and set the ID value to DestinationsCheckboxList. On the next line, drag a Button control to the page, set the ID to shipbutton, and set the Text to ship. Below that, drag a Label control to the page, set the ID value to shippingConfirmationLabel, and clear the default Text value. Your form should now resemble Figure 4-10.

CHAP version 2 (MS-CHAPv2) option is selected. In the VPN Strategy drop-

Without type safety, there s no way to reliably enforce security restrictions Related to managed code is managed data Managed data is data that is allocated and freed automatically through the runtime using a process called garbage collection With garbage collection, whenever an allocated item goes out of scope, the runtime cleans it up One consequence of using garbage collection is that the time and potentially even the order of destruction of objects can t be determined For instance, consider the following C# code snippet (I ll introduce C# in 3; but even without knowing anything about C#, you should be able to understand this simple example) class MainApp { public static void Main() { SystemString Hello = "Hello"; SystemString World = "World!"; SystemConsoleWriteLine(Hello); SystemConsole.

Now you will write code to add any text typed in the Name box to the DestinationsCheckBoxList. Double-click the Add button to create an event handler for Button.Click, and then write the necessary code.
