Finding the right website
It seems that the standard answer to so many questions is now "look on the net". There was a time when children would pester their parents and teachers with a lot of questions and demand instant answers. It was frustrating for the adults because, contradictory to what children think, they did not have all the answers ready at the front of their minds. Some questions would require a little thought and others need to be properly researched, before they could reply.
These days, when a child asks about a particular subject, topic or query, they are told that they should look for the answer on the computer. In this way, we are finding that children now check the computer and websites before they ask their parents a question. When it comes to homework, checking answers and doing research, the internet is the preferred medium of choice for people these days.
There will be a website for almost any subject that you can think of and it is up to adults to control the way that their children use the computer. It is so easy to forget that even though the internet is a wonderful tool for extracting information, it does have its own set of problems and so regular monitoring is necessary where children are concerned. When you need to obtain information on something, make sure that you only visit reliable websites as there are many which will cause you harm, in different senses of the word.
When should I use WPF instead of DirectX?
DirectX is definitely not dead and is still more appropriate than WPF for advanced developers writing hard-core “twitch games” or applications with complex 3D models where you need maximum performance. That said, it’s easy to write a naive DirectX application that performs far worse than a similar WPF application. DirectX is a low-level interface to the graphics hardware that exposes all of the quirks of whatever GPU a particular computer has. DirectX can be thought of as assembly language in the world of graphics: You can do anything the GPU supports. WPF provides a high-level abstraction that takes a description of your scene and figures out the best way to render it, given the hardware resources available. Internally, this might involve using Shader Model 3.0, or the fixed-function pipeline, or software. (Don’t worry if you’re not familiar with these terms, but take it as a sign that you should be using WPF!). The downside of choosing DirectX over WPF is a potentially astronomical increase in development cost. A large part of this cost is the requirement to test your application on each driver/GPU combination you intend to support. One of the major benefits of building on top of WPF is that Microsoft has already done this testing for you! You can instead focus your testing on low-end hardware for measuring performance. The fact that WPF applications can even leverage the client GPU over Remote Desktop or in a partial-trust environment is also a compelling differentiator.
What is OOP?
OOPs - Object Oriented Programming Languages & Systems
Everything in the world is an object. The type of the object may vary. In OOPS, we get the power to create objects of our own, as & when required. OOPs is a programming methodology where each entity is an object.
It is a method of computer programming where entities of related data together with routines associated with it are treated as one object in the program.
Hosting ASP.NET Pages
Hosting ASP.NET pages locally through the ASP.NET Development Web Server has a number of advantages:
* Testing can be done while offline-Because the request from your browser is being directed to your own personal computer, you don’t need to be connected to the Internet to test your ASP.NET pages.
* It’s fast-Local requests are, naturally, much quicker than requests that must travel over the Internet.
* Advanced debugging features are available-By developing locally, you can use advanced debugging techniques, such as halting the execution of an ASP.NET page and stepping through its code line-by-line.
* It’s secure-The ASP.NET Development Web Server allows only local connections. With this lightweight web server, you don’t need to worry about hackers gaining access to your system through an open website.
The main disadvantage of hosting ASP.NET pages locally is that they can be viewed only from your computer. That is, a visitor on another computer cannot enter some URL into her browser’s Address bar that will take her to the ASP.NET website you’ve created on your local computer. If you want to create an ASP.NET website that can be visited by anyone with an Internet connection, you should consider using a web-hosting company.
Web-hosting companies have a number of Internet-accessible computers on which individuals or companies can host their websites. These computers contain web servers that are accessible from any other computer on the Internet. Hour 24, “Deploying Your Website,” explores how to move an ASP.NET website from your personal computer to a web-hosting company’s computers. After a website has been successfully deployed to a web-hosting company, you, or anyone else on the Internet, can visit the site.
