If we were now to go on to de ne a JointAccount class, the temptation would be to say that since this is a specialized form of account, we should inherit BankAccount and add in the additional member However, inheritance is computationally costly in a number of ways, and if we can legitimately avoid using it our program will be more ef cient The question to ask is whether any of the operations for a BankAccount will need to be signi cantly changed for a JointAccount I would answer no to this question, since all of the main operations of an account could deal with either one or two account signatories without any need for inheritance Instead, the composition relationship could be extended as in Figure 106 Now the code for BankAccount will have to become a little more complex, since we will need to provide a method to optionally add in a second customer, and we will also have to check for a second customer when generating a statement However, we have saved having to use inheritance, a bene t in itself, and more importantly, we have made it possible to convert any BankAccount into a joint account by simply adding a second customer at any time Using inheritance, converting from a standard account to a joint account would have involved a nightmare of code to create the new type of account, copy all of the existing data over to it (including all of the transactions), add in the second ustomer s information and then destroy the original account Instead we have replaced an inheritance relationship with a much simpler (and computationally cheaper) composition one Of course if an unlimited number of signatories were to be possible, we would need to deal with an aggregation of account names, and this might make it worth creating a new class that inherits from BankAccount In designing class models, there are always likely to be possible alternative implementations of the ideal situation The best choice of data structure (eg between an ArrayList, a HashTable and a Dictionary) is not always obvious Similarly, the choice between a simple composition (using reference variables in a class de nition) and an aggregation (using one of the Collection class objects) is usually not clear cut While the best solution is often to choose the most simple and direct approach (eg having the space for two Customer objects in a bank account), sometimes this approach can impose a limitation on a class design that will only be apparent later Software design is as much an art as a science, and while learning to use the facilities of a programming language is a relatively simple matter, learning how and when these facilities should be employed is much more dif cult and comes only with experience Examining program code, whether from books like this, magazines, journals or on-line is valuable; working with code by copying and.

a data, size, image with visual c# barcode sdk. .We ve said much regarding the theory of ColdFusion component inheritance, and rankly, much of it is seriously overblown. Inheritance shares its name with the object-oriented world, but that s about all that it shares. CFC inheritance can be easily summed up with the following three simple statements: One component can inherit from or extend another, after which the inheriting component can make use of its ancestor s properties and methods. If the inheriting component declares its own methods named differently from those in its ancestor, both the ancestor s methods and the inheriting component s methods can be called through the inheriting component. The same holds true for declaring properties by using names that do not match their ancestor s. If the inheriting component declares its own methods named the same as those in its ancestor, the inheriting component s methods override the ancestor s methods with the same name, as if the ancestor s methods are hidden. The same holds true for declaring properties by using names that match their ancestor s. Just keep these three simple principles in mind as you proceed through the following sections and don t think that inheritance is any more complicated than this. Inheritance has a few applications in real-world ColdFusion development, but you re likely to find that they are rare. Nevertheless, you should understand inheritance so that you can spot places in your application where it may be warranted.Related: .NET Data Matrix Generating , VB.NET Data Matrix Generating , Intelligent Mail Generator .NET WinForms

We ve shown you how to create COM add-ins and Custom Task Panes using Visual Studio 2005 The examples presented so far demonstrate how to implement these components using Visual Studio without Visual Studio Tools for Of ce (VSTO) If you install the latest version of VSTO, Visual Studio 2005 Tools for the 2007 Microsoft Of ce System (or VSTO 2005 SE for short), there is an even easier way to create add-ins and Custom Task Panes In fact, you don t need to know much or anything about COM These add-ins use pure managed code! Besides using managed code, the new managed add-ins also have another advantage they are loaded into their own application domains This means that if one add-in crashes (ie throws an exception), neither the application nor other add-ins are affected Let s take a look at how easy it is to implement these new managed add-ins The samples for this chapter include a managed add-in project called TrackBarTaskPane This sample is a managed add-in that implements a Custom Task Pane In this task pane is simply a TrackBar control (otherwise known as a slider control) When the task pane is loaded and you load a form in InfoPath that has at least one eld, the value of the eld will change as you position the track bar in the task pane This is a very simple example that demonstrates how to implement a managed add-in and Custom Task Pane using VSTO 2005 SE To implement this sample, we re going to perform the following steps 1 Create the managed add-in using VSTO 2005 SE 2 Create a User Control that will be hosted in the Custom Task Pane 3 Add a TrackBar control to the User Control 4 Add the User Control to the CustomTaskPanes collection 5 Show the Custom Task Pane Let s discuss in more detail how this is implemented.

Add in network interface cards on PC, server, routers, and switches, and you have a dozen or more points f failure. What if the backplane on a switch fails Or one outbound interface card on a router Each one of these pieces of equipment may be controlled by a different operations organization, adding a people angle to the complexity. Latency contributes to perceived network failures. A router that is overloaded or dropping packets in the middle of a long network path will greatly impact end-to-end reliability. Network design and traffic management help to reduce network latency, or at least control it, but it remains an external factor in service reliability measurement. Denial-of-service attacks are real. Most simply, a denial-of-service attack means that a user cannot get access to a host or network service because all of the input capacity is tied up dealing with bogus requests. Here s a simple example using the ever-popular bank teller model: Five people simultaneously cash their paychecks, take the amount in pennies and unwrap them, then ask to deposit the pennies by counting them. All other bank customers queued for a teller are stuck while the bogus requests are handled. All real work is held pending while the annoyance requests are serviced.

Then, just as she got these functions working and was about to leave on a trip to the West coast to work with Arthur, she obtained some code from Dick that allowed her to annotate displayed documents using the GlassPane methods of the JFrame component This is hown in Figure 343 Working under cramped conditions on the flight, she integrated that code into the working program and showed it to Arthur on her arrival He was impressed with the program so far After working with Sandy for a day or so and integrating her server technology, he was even more pleased with their joint work But Sandy was less pleased because she knew that they had just hastily written a tangle of interacting classes that was nearly impossible to maintain or understand When she expressed her concerns to Arthur, he took a familiar textbook off the shelf "Here's a copy of Design Patterns, " he said "I think you'll find some good ideas on how to modify our program to be less confusing" Sandy took the book back to her motel room and began thumbing through the catalog of patterns By the next day, she had the beginnings of some ideas "Look," she said, "we can look at this program as a set of data objects or as a set of visual objects Either way, we have to minimize the amount that each object needs to know about the others, so we can modify an object without changing any others If we consider the applet as a set of data interaction objects, then the toolbar buttons call on data and change display elements Clicking on the Search button produces a list of terms and documents Clicking on a document in the list causes a display of the abstract Clicking on a term and then on "Add term" causes that term to be added to the query field Clicking the document and then on the View button causes that document to display in the viewer 5 Clicking on a term and then on the Plot button causes a plot of related terms to be generated 1 2 3 4.
