ASP.NET PDF Viewer using C#, VB/NET

When you face the limited capacity of the working memory of your audience to process new information, a core challenge is not creating the visuals and narration, but rather determining the underlying structure that will shape those elements in the rst place. A structure focuses your ideas and helps you gure out what you want to say and how you want to say it. That s where an incredibly powerful structural tool you will use comes into play the BBP Story Template.

Note It s worth pointing out that a model called Class wouldn t be allowed in Rails, because there s already a class called Class built in to Ruby. Beware of reserved words and using names that are already used elsewhere!

The variety of relationships possible are documented in the official Ruby on Rails documentation at http://www.rubyonrails.org/api/classes/ActiveRecord/ Associations/ClassMethods.html.

Listing 2-1 contains an example program that asks you for a year, a month (as a number from 1 to 12), and a day (1 to 31), and then prints out the date with the proper month name and so on. An example session with this program might be as follows: Year: 1974 Month (1-12): 8 Day (1-31): 16 August 16th, 1974 The last line is the output from the program.

With the lessons of the dual-channels theory from 2 in mind, lmmaking is an appropriate model for designing multimedia presentations because it plans and manages both visual and verbal information simultaneously. Filmmakers know that the best way to start planning a lm is with the written word, in the form of a script. A script is much shorter and less detailed than a novel because it assumes that the visuals and dialog will play a major role in telling the story. The best scripts distill stories to their bare essence and strip away anything that does not contribute to a story s singular focus. When a writer completes a script, the document then becomes a powerful organizing tool that literally puts everyone on the same page. The script is the starting point for planning and producing visuals and dialog, and it serves as a way for everyone involved in the project to be clear on what everyone else is saying and doing. If you were a lmmaker and you started lming before you had a script similar to working on a PowerPoint presentation without a written structure you would probably waste time and resources while you changed your focus and gured out the story along the way. Although putting your thoughts in writing adds a new step to your usual PowerPoint process, doing so will save you time and effort later. When you begin writing your PowerPoint script next in 4, you won t have to start with an empty page, because you ll use the story template shown in Figure 3-2 to guide you every step of the way.

A useful feature provided by Rails applications out of the box is support for sessions When a Web browser makes a request to your application, Rails silently sends back a cookie containing a unique identifier for that browser Whenever that browser makes further requests, it sends back the cookie with the unique identifier, so the application always knows when a certain previous visitor is making another request You can use the session s ability to store information that s specific to a particular visitor for use on future requests Sessions are commonly used on Web sites for features such as shopping carts or keeping track of what pages you ve visited For example, if you add an item to your cart at an e-commerce site, the item chosen is stored in a data store associated with your session s ID.
