Some classes (particularly those related to user interactions) need to expose a very large number of events. If you use the normal event syntax shown in the preceding examples, storage is allocated for every single event you declare, even if the events have no subscribers. This means that objects of this type can get very large, very quickly. To avoid this situation, C# provides you with the ability to manage storage for the events yourself, using syntax similar to a property getter and setter, with your own backing storage: c# open pdf adobe reader How to popup window which will show my one PDF file ? - ASP .

30 Jan 2017 ... We are going to use iTextSharp library in this article. It is an open source library and very useful to CREATE, ADAPT, INSPECT and MAINTAIN ... public event EventHandler MyEvent { add { // Code to add handler here } remove { // Code to remove handler here } } The reason we decrypt with the secret key is that we only want the signer to be able to create signatures. However, we want anybody to be able to verify the signature with the public key. As such, to verify a signature, given a public key, we can use the following test to compute V(), our verification function: Typically, you use a Dictionary<Key,Val> to create the backing storage for the event only when it gets its first subscriber. (Dictionaries are described in 9.) Example 5-32 updates the DocumentProcessor we re developing in this chapter to use a dictionary for the backing storage for its events. c# convert pdf to tiff pdfsharp, pdf to tiff c# code, utility to convert excel to pdf in c#, gtin 14 check digit excel formula, c# pdfdocument, itextsharp add annotation to existing pdf c# c# code to view pdf file How create a PDF viewer with iText and C - C# Corner

If the encryption of s with the public key yields the hash of the message, then we know the signature is authentic and the expression returns true, or else the signature verification fails and V() returns false. c# winforms pdf viewer control free pdf viewer c# free download - SourceForge

Obviously, that s a lot more complex than the automatic method, and you would not normally use it for a class that exposes just a couple of events, but it can save a lot of working set for classes that are either large in number, or publish a large number of events but have few subscribers. Click the wrench icon to set the operation and the inputs for the RSS block. Return to the block window, and drag and drop a News Reader block onto the design surface to the right Summary In this chapter, we saw how functional techniques provide powerful reuse and extensibility mechanisms for our programs, in ways that can be more flexible and yet simpler than class-based approaches. We also saw how events enabled a publisher-to-multiplesubscribers relationship. In the next chapter, we ll look at how we deal with unexpected situations: errors, failures, and exceptions. Errors happen all the time; they re a fact of life: Despite the best efforts of Microsoft Word, an army of highly skilled reviewers and editors, and even your authors, it would be surprising if there wasn t a typographical error in a book of this length. Although they are relatively few and far between, there are bugs in the .NET Framework hence the need for occasional service packs. You might type your credit card number for an online transaction and accidentally transpose two digits; or forget to type in the expiration date. Like it or not, we re going to have to face up to the fact that there are going to be errors of all kinds to deal with in our software too. In this chapter, we ll look at various types of errors, the tools that C# and the .NET Framework give us to deal with them, and some strategies for applying those tools. First, we need to recognize that all errors are not made the same. We ve classified a few of the more common ones in Table 6-1. c# .net pdf viewer Display PDF file in winform - C# Corner
