In this article, Sergey examines the role of cross domain access policy in Silverlight. After a short introduction, he examines the interaction between client and server as well as a list of threats which may occur in rich internet applications. He also provides steps to take in order to prevent attacks and operation of Crossdomain Client Access Policy with the help of relevant screenshots and source code.

In this article, I will illustrate how LINQ makes the relation between objects and data easy to deal with. I will also use code samples to make a comparison between regular code and LINQ code.

Explore the process of creating the files to support DeepZoom composition (image pyramids and dz xml files). Assumes a basic understanding of deepzoom. The foundation for the article can be seen on my blog: problog.jamespritz.com.

This article describes the basics of developing an animation application using the Silverlight Application project found in Visual Studio 2008 SP1.

It displays various status information about the current upload, just like pure HTML progress bar but instead of popup window it uses an inline progress bar with the AJAX technology. KFileUploadPlusProgressBa r Control takes full advantage of AJAX and the new features of Microsoft's next- generation IDE - Visual Studio .NET 2005, hence allowing developers to enjoy significant productivity gains, while delivering feature-rich, standards-compliant and cross- browser compatible web applications. developers to enjoy significant productivity gains, while delivering feature-rich, standards-compliant and cross-browser compatible web applications.

Since then, mailing lists, newsgroups, and web sites have sprung up containing a mixture of code samples, applications, and articles of various forms. Even if you're not a programmer using existing ASP technology, it's a good bet that you've at least heard of .NET, even if you aren't quite sure what it involves. After all, there's so much information about .NET, that it's sometimes hard to filter out what you need from what's available. With new languages, new designers, and new ways of programming, you might wonder exactly what you need to write ASP.NET applications.

A Sample Chapter from "Beginning ASP.NET using VB.NET". Topics covered include: Static Web Pages Dynamic Web Pages; An overview of the different technologies for creating dynamic web pages, including ASP.NET; Installing Internet Information Services (IIS); Installing the .NET Framework; and Testing and Troubleshooting your installation.

Programming an ASP.NET application is significantly different than programming in ASP.old. The difference can be likened to the change that occurred when moving from QuickBasic programming to Visual Basic programming.

In this article we will learn how to determine the size and dimensions ( width & height ) of an uploaded image? allow the image to be uploaded if it is less than given size? or if it's width and height are less than given values? and finally how to resize an image to create thumbnails?

Visual Basic .NET has not only extended the versatility of the Visual Basic language but also harnessed the power of the .NET framework, the new "Delegate" feature is one of them. So now you don't get the sneer of the self proclaimed C++ or Java programmers looking down on VB programmers as mere mortals!

Microsoft is set to release an exciting upgrade to ASP later in 2000. This is a major upgrade unlike the minor changes from ASP 2.0 to 3.0. Unlike past upgrades, however, this one will not be painless. When they designed ASP+, Microsoft had to make the hard decision occasionally to break backward compatibility in the interest of improved functionality and features.

Microsoft is investing millions in promoting .NET and its advantages. One of the many plugged advantages of the Microsoft .NET initiative is XML Web Services the ability to remove your business logic from custom DLLs and COM/DCOM components (helping to avoid DLL hell) and hosting your middle tier business logic as Web Services, which can be accessed by all your applications (Web Sites, Distributed Applications, etc.)

I'm sure you've probably heard (since I've done nothing but talk about it) that we recently went to San Jose to put on our very own ASP.NET Developer Conference & Expo. While we were there, we talked to a number of developers and got a good feel for what the attendees were most looking forward to in ASP.NET. One of the things that kept coming up was the ability to use code-behind to separate the display and layout of an ASP.NET page from it's code and application logic.

Have you ever needed to have an image of some text generated dynamically on the fly? There are tons of possible applications for this type of thing which I won't go into, but prior to ASP.NET it was a relatively difficult thing to do. Well no more...

This tutorial will help you figure out how to write Web applications using Microsoft's most current version of its HTTP request processing framework - ASP.NET 2.0.

This tutorial covers managing session state within your ASP.NET application. Programming Web applications requires you to be very mindful of how the state of your application is distributed at any moment. One of the most important types of state in a Web application is session state - the state associated with a single particular session. Because Web applications are distributed by nature, keeping track of any single client has to be done deliberately.

This tutorial covers ASP.NET's built-in data caching features. Caching is a long-standing means of improving the performance of any software system. The idea is to place frequently used data in quickly accessed media. Even though access times for mass storage continue to improve, accessing data from a standard hard disk is much slower than accessing it in memory. By taking often-used data and making it available quickly, you can improve the performance of your application dramatically.
