In this case, the variable is created even if there s already another variable with this name and you d see both variables in the Keys collection. The Application object exposes a subset of the properties and methods of the Session object, including Contents, StaticObjects, Add, Clear, Remove, RemoveAt, and RemoveAll. Application variables are somewhat less important in ASP.NET than they were under ASP, because the .NET Framework supports the more capable Cache object to store application-level state, as I explain in The Cache Class section, later in this chapter. Don t forget that application variables are lost when the ASP.NET process is stopped or recycled. If you want to preserve the application s state when this happens, you should write code for the Application_OnEnd event in Global.asax to save it to a persistent medium and restore it in the Application_Start event handler. Application recycling is a great feature that lets you configure an application so that ASP.NET automatically shuts it down and restarts it after a given period or a given numZ ber of client requests, or when it consumes more memory than the specified threshold. This feature is a lifesaver if the application progressively degrades its performance because of memory leaks which can happen if the application uses unmanaged resources. You control application recycling by means of one or more settings in the <processModel> tag in web.config. For example, this setting recycles the ASP.NET application every hour:

public interface IDoor { void Lock(); void Unlock(); Boolean IsDoorOpen { get; }

26:

Int32 OpenTimeout { get; set; } event EventHandler DoorOpenForTooLong; }

For more information about application recycling, read the section about the <processModel> tag, in 27.

The apparent plus of this design is that it gives you just one interface that can serve up both scenarios: timed and regular doors. This is an apparent benefit because it forces you to have two extra members on any class that implements the interface: the event DoorOpenForTooLong and the timeout property. Why on earth should you have these members where they aren t needed

Print UPCA EAN13 Bookland Barcode from Crystal Reports
To print Upc-A barcode in Crystal Reports , what you need is Barcodesoft UFL ( User Function Library) and UPC EAN barcode font. 1. Open DOS prompt.

Note also that code that is not strictly needed can t be ignored after it is compiled. In other words, any code that gets compiled does count, regardless of whether or not it was necessary when you designed your classes. Because it s there, it can influence the application, it must be tested, it must be debugged, and it must be maintained. Quite paradoxically, because it s there it can even represent a constraint and limit further necessary improvements! The natural solution is to use slimmer interfaces. The IDoor interface should be split into two smaller and much more specific interfaces say IDoor and ITimedDoor:

ASP.NET developers have several options for places they can store values used by applications. In fact, unlike Windows Form applications, ASP or ASP.NET programming is stateless, which means that variables aren t preserved between consecutive requests to the same (or a different) page of the same application. Let me quickly review the advantages and shortcomings of the techniques available to ASP developers for storing state between consecutive requests:

public interface IDoor { void Lock(); void Unlock(); Boolean IsDoorOpen { get; } } public interface ITimedDoor { Int32 OpenTimeout { get; set; } event EventHandler DoorOpenForTooLong; }

Client-side cookies Because data travels back and forth at each request to a page of the application, you can use this technique only for small amounts of data Of course, it doesn t work at all if the end user has disabled cookie support in the browser A great advantage of this technique is that values can be persisted between consecutive visits to the same site Session variables You can use session variables for larger amounts of data than cookies, but each variable takes memory on the server, so this technique impedes scalability Worse, ASP sessions don t work on Web gardens or Web farms, so your application can t easily scale out to multiple processes or multiple servers.

Now if you need to create RegularDoor and TimedDoor classes, you proceed as shown here:
