Silverlight Recipes : Controls - Customizing the Default ListBoxItem UI

In data-bound ListBox scenarios, you typically do not explicitly add each individual item that the ListBox displays.

ASP.NET 3.5 : Caching ASP.NET Pages (part 4) - Advanced Caching Features

The output caching subsystem has also a few other cool features to offer. They are caching profiles and post-cache substitution. In brief, caching profiles let you save a block of output caching-related settings to the configuration file.

ASP.NET 3.5 : Caching ASP.NET Pages (part 3) - Caching Portions of ASP.NET Pages

The capability of caching the output of Web pages adds a lot of power to your programming arsenal, but sometimes caching the entire content of a page is not possible or it’s just impractical.

ASP.NET 3.5 : Caching ASP.NET Pages (part 2) - The HttpCachePolicy Class, Caching Multiple Versions of a Page

Depending on the application context from which a certain page is invoked, the page might generate different results. The same page can be called to operate with different parameters, can be configured using different HTTP headers, can produce different output based on the requesting browser, and so forth.

ASP.NET 3.5 : Caching ASP.NET Pages (part 1) - The @OutputCache Directive

Caching the output of a page is as easy as defining an @OutputCache directive at the top of the page. The directive accepts a handful of attributes, a couple of which—Duration and VaryByParam—are mandatory.

ASP.NET 3.5 Social Networking : Messaging (part 4) - Implementing the presentation layer

We are going to need at least three pages to really utilize our messaging features. We will need a way to create and send a new message, a way to receive and view the messages, and a way to read an individual message.

ASP.NET 3.5 Social Networking : Messaging (part 3) - Implementing the services/application layer

Once all the repositories are built for single serving, we can begin to create the services layer. Again, this layer is responsible for assembling aggregates and performing complex actions with our entities.

ASP.NET 3.5 Social Networking : Messaging (part 2)

A message will primarily be made up of the subject and its body. In addition to that we will need to know what type of message we are sending so that we can do some more fancy things in the UI down the road.

ASP.NET 3.5 Social Networking : Messaging (part 1)

Messages are the core of any messaging system. Generally, a message would contain details on the sender of the message, receiver of the message, and other metadata about the message, subject, and body.

How To Use Skype To Help Your Business

SKYPE IS SO popular that some people use its name as a verb. Yet more people use Skype only for making free voice calls, and for occasional video chats. That’s a shame, because Skype is a powerful business tool. A Skype-powered videoconference can take the place of a business trip, not to mention the free Skype-to-Skype calls you can make to overseas suppliers and clients.

ASP.NET 4 in VB 2010 : Reading and Writing with Streams (part 2) - Shortcuts for Reading and Writing Files, A Simple Guest Book

.NET includes functionality for turbo-charging your file writing and reading. This functionality comes from several shared methods in the File class that let you read or write an entire file in a single line of code.

ASP.NET 4 in VB 2010 : Reading and Writing with Streams (part 1) - Text Files, Binary Files

The .NET Framework makes it easy to create simple "flat" files in text or binary format. Unlike a database, these files don't have any internal structure (that's why they're called flat). Instead, these files are really just a list of whatever information you want to store.

Amazon Isn’t Just For Books Anymore...

While we’re used to Amazon -the massive online retailer that we all know, and some love - providing a huge array of products, you may be unaware that it also provides a range of tools and services aimed at the IT market, too.

Transferring Bookmarks With Internet Usernames And Passwords To A New PC

If you were lucky enough, upon un-wrapping the gaily coloured boxes under your tree, to find that one of them contained a brand spanking new computer, the odds are after jumping with joy you will have realised that you now faced the onerous task of getting the blasted thing up.

The Benefits Of A Technet Subscription (Part 2)

Although the word ‘evaluation’ sticks in the throats of many a reader, consider this: if you were to buy Windows 8 Pro, along with Office 2010 for your computer, then the overall cost to you would be in the region of $480. Should that package then turn out to be the wrong choice, it would be money ill-spent (although you can refund it), but the time taken to install configure and test would have been wasted as well.

The Benefits Of A Technet Subscription (Part 1)

The best way to gain experience with a particular piece of software is to actually roll up your sleeves and get stuck in. Installing it multiple times, trying out different installation combinations, setting the product up, customising it and getting used to its common features will give you more experience than could ever be garnered from the pages of a book or magazine.

How To Find The BEST DEALS (Part 2)

Most hardware sales websites have a special discount, clearance or outlet section, which is used to get rid of stock that can’t be sold as new for one reason or another. The products in them aren’t necessarily second-hand (although they might be, particularly if they’re described as ‘open box’), but they are cheaper, and usually by a significant amount

How To Find The BEST DEALS (Part 1)

Looking for bargains, as with any human endeavour, is 1% inspiration and 99% perspiration. In this case, the latter normally occurs when you’re crammed into crowded shops fighting over marked-down goods in the January sales.

How To Make The Most Of The Second Hand Market (Part 2)

If someone mentions buying or selling goods second hand, it’s a safe bet that your brain will go straight to thinking about eBay. It’s not hard to see why: the website has been around longer than most and has crushed the competition over the years with its wide range of content and reliable system of sales.

How To Make The Most Of The Second Hand Market (Part 1)

The fast pace at which the computing industry moves means that there’s always a new and desirable piece of technology just around the corner. A bigger monitor, a better graphics card, a more powerful CPU. The fast turnover may be the bane of those who like to stay on the bleeding edge, but if you’re content to have a more mid-field system, it has a huge advantage.

Microsoft ASP.NET 3.5 : Caching Application Data (part 5) - SQL Server Cache Dependency

Many ASP.NET applications query some data out of a database, cache it, and then manage to serve a report to the user. Binding the report to the data in the cache will both reduce the time required to load each report and minimize traffic to and from the database.

Microsoft ASP.NET 3.5 : Caching Application Data (part 4) - Designing a Custom Dependency, A Cache Dependency for XML Data

Suppose your application gets some key data from a custom XML file and you don’t want to access the file on disk for every request. So you decide to cache the contents of the XML file, but still you’d love to detect changes to the file that occur while the application is up and running. Is this possible? You bet. You arrange a file dependency and you’re done.

Microsoft ASP.NET 3.5 : Caching Application Data (part 3) - Practical Issues

Caching is a critical factor for the success of a Web application. Caching mostly relates to getting quick access to prefetched data that saves you roundtrips, queries, and any other sort of heavy operations.

Microsoft ASP.NET 3.5 : Caching Application Data (part 2) - Working with the ASP.NET Cache

An instance of the Cache object is associated with each running application and shares the associated application’s lifetime. The cache holds references to data and proactively verifies validity and expiration. When the system runs short of memory, the Cache object automatically removes some little-used items and frees valuable server resources.

Microsoft ASP.NET 3.5 : Caching Application Data (part 1) - The Cache Class

The Cache class is exposed by the System.Web.Caching namespace and is a new entry in the set of tools that provide state management in ASP.NET. The Cache class works like an applicationwide repository for data and objects, but this is the only aspect that it has in common with the HttpApplicationState class, as we’ll see in a moment.

Twitter On Trial

It’s difficult to remember a time before Twitter. Though the micro-blogging service is still relatively young, the Internet and our daily lives are awash with words like ‘tweet’, ‘tweeters’ and ‘trending’.

Version 5.1.7 is the most recent version and it dates back to May this year. That might not seem very long ago, but in web browser development terms it certainly is.

Group Test: Web Browsers (Part 2) : Internet Explorer 10, Chrome 23

Internet Explorer 10 shipped as part of Windows 8. In fact, there are two versions of the web browser: one is on the Start screen and the other runs on the desktop. The Start screen app is very different and has a touch-enabled interface that you will love or hate. The desktop version of IE10 will be available for Windows 7 by the time you read this, at least in preview form, if not the full release version.

Group Test: Web Browsers (Part 1) : Firefox 17, Opera 12.10

The pace of development of web browsers is incredibly rapid, with new versions coming along every few weeks. Firefox 16 was released a month ago, 17 will be released next week, 18 will be here in January and there’s talk of 19 not long after that. Wow! In the hope of reviewing something that might actually still be around when you read this, on test is Firefox 17 beta.

Html 5 : Text Tags and a Little CSS3 - Adding More HTML5 Structure

The hgroup element is tied into the outline algorithm in HTML5, and although it’s unlikely that you’ll be using it for writers like Wittenstein, it is useful for helping you think about your page in terms of the structure within an HTML5 page.

Html 5 : Text Tags and a Little CSS3 - The Fundamentals

When you’re organizing a Web page, the links should be organized into a navigation system that’s easy for those looking at your Web page to use. In the page shown in Figure 1, the link is broken up by the graphic and seems to be part of the text rather than part of a navigation system.

Microsoft SharePoint 2010 Web Applications : Presentation Layer Overview - Ribbon (part 2) - Complex Event Handling

The preceding examples have shown you how to handle events using embedded JavaScript; although this works well, as the JavaScript becomes more complex, it gets increasingly difficult to manage. A common approach to dealing with this problem is to maintain scripts as separate files.

With SharePoint 2010, the biggest single change from a user interface perspective is the introduction of the ribbon. With previous versions, controls and menus were spread between a few components.

Microsoft SharePoint 2010 Web Applications : Presentation Layer Overview - Executing Server-Side Code

Another difference between site pages and application pages is the way they are parsed by the SharePoint platform. Application pages behave like any other ASP.NET page in that they can contain inline server-side code; however, site pages are rendered using the safe mode parser that prevents inline server-side code from executing.

Should You Have Mobile Web Designers?

Forrester Research (www.forrester.com) predicts that 1 billion consumers worldwide will own smartphones by 2016. Of these, 350 million will be employees using their devices in a work-oriented capacity. It isn't surprising, then, that Forrester expects business spending on mobility to double by 2015.
