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. c# itextsharp pdfreader not opened with owner password How to read PDFs created with an unknown random owner ... - iText

So far we have discussed printing only an image or a single-page file Printing multipage files is another important part of printing functionality that developers may need to implement when writing printer applications Unfortunately, the NET Framework does not keep track of page numbers for you, but it provides enough support for you to keep track of the current page, the total number of pages, the last page, and a particular page number Basically, when printing a multipage document, you need to find out the total number of pages and print them from first to last You can also specify a particular page number If you are using the default Windows printing dialog, then you don't have to worry about it because you can specify the pages in the dialog, and the framework takes care of this for you To demonstrate how to do this, our next program produces a useful printout showing all he fonts installed on your computer This program is a useful tool for demonstrating the calculation of how many pages to print when you're using graphical commands to print We will use the PrintPreview facility to display the output in case you don't have access to a printer In this example we need to track how many fonts have been printed and how far down the page we are If we're going to go over the end of the page, we drop out of the pd_PrintPage event handler and set evHasMorePages to true to indicate that we have another page to print To see this functionality in action, let's create a Windows application and add a menu with three menu items and a RichTextBox control to the form The final form is shown in Figure 1124.
