Microsoft ASP.NET 3.5 : Writing HTTP Handlers (part 1) - The IHttpHandler Interface

Want to take the splash and dive into HTTP handler programming? Well, your first step is getting the hang of the IHttpHandler interface. An HTTP handler is just a managed class that implements that interface.

Microsoft ASP.NET 3.5 : HTTP Handlers and Modules - Quick Overview of the IIS Extensibility API

A Web server is primarily a server application that can be contacted using a bunch of Internet protocols, such as HTTP, File Transfer Protocol (FTP), Network News Transfer Protocol (NNTP), and the Simple Mail Transfer Protocol (SMTP).

Programming WCF Services : Queued Services - The HTTP Bridge

The MSMQ binding is designed to be employed in the intranet. It cannot go through firewalls by default, and more importantly, it uses a Microsoft-specific encoding and message format.

Microsoft ASP.NET 4 : Ajax - Extender Controls (part 2) - A Modal Pop-up Dialog-Style Component

AJAX provides another interesting feature that makes Web applications appear more like desktop applications: the ModalPopup extender. Historically, navigating a Web site involves users walking down the hierarchy of a Web site and climbing back out.

Microsoft ASP.NET 4 : Ajax - Extender Controls (part 1) - The AutoComplete Extender

After creating the new template, you will need to configure your domain for autoenrollment. If you have already deployed Active Directory Certificate Services for other PKI-dependent applications, you may have already enabled this setting.

Mobile Handheld Devices : DATA SYNCHRONIZATION

Synchronization connects handheld devices to desktop computers, notebooks, and peripherals in order to transfer or synchronize data.

Mobile Handheld Devices : MEMORY, STORAGE AND BATTERIES

PDAs normally have more storage space than smart cellular phones, with the former commonly having 64 Mbytes, and the latter a memory size that may be as low as a few Mbytes.

LINQ to Objects : How to Return Elements When the Result Is a Sequence (Select Many)

The SelectMany standard query operator flattens out any IEnumerable result elements, returning each element individually from those enumerable sources before moving onto the next element in the result sequence.

LINQ to Objects : How to Change the Return Type (Select Projection)

When you write queries against a database system in SQL, specifying a set of columns to return is second nature. The goal is to limit the columns returned to only those necessary for the query in order to improve performance and limit network traffic (the less data transferred, the better).

A Technical Overview of the Mobile Web : OTHER MOBILE TECHNOLOGIES

For many years, the main way of locating a mobile device was a cellular-based process: by triangulating the relative positions of cell towers, a mobile carrier could determine a reasonable position for the device.

A Technical Overview of the Mobile Web : THE MOBILE NETWORK

Mobile devices are very complex pieces of technology and must be understood well if you are to deliver web-based content to them. The same is true of the vast (and even more complex) networks to which they connect.

Programming WCF Services : The Response Service (part 4) - Transactions

Since a response service is just another queued service, the mechanics of managing and participating in a transaction are just like those of any other queued service.

Programming WCF Services : The Response Service (part 3) - Queued Service-Side Programming & Response Service-Side Programming

The response service accesses its response context, reads from it the method ID, and responds accordingly. Example 7 demonstrates a possible implementation of such a response service.

Programming WCF Services : The Response Service (part 2) - Client-Side Programming

A queued response service is not limited to being used only with a queued service. You can use the same technique to pass the address and method ID to a connected service and have that service respond to a client-provided queued response service.

Programming WCF Services : The Response Service (part 1) - Designing a Response Service Contract

As with any WCF service, the client and the service need to agree beforehand on the response contract and what it will be used for; that is, whether it will be used for returned values and error information, or just returned values.

Programming WCF Services : Queued Versus Connected Calls - Requiring Queuing

Since not every service can be connected and queued, and since some services may be designed for a particular option and only that option, WCF lets you constrain a service’s communication pattern.

Programming WCF Services : Queued Services - Playback Failures

With MSMQ 4.0 (available on Windows Vista, Windows Server 2008, and Windows 7 or later), WCF retries playing back a failed message in series of batches, for the reasoning just presented. WCF provides each queued endpoint with a retry queue and an optional poison messages queue.

DotNetNuke Skinning : Package and Deploy

Packaging your skin is not necessary to use the skin. Packaging is also not necessary to move or deploy your skin on another DotNetNuke install or a different server.

Unit Testing in Visual Studio 2010 (part 2) - Running a battery of tests

You should be able to run your tests with the click of a mouse or by entering a single command. To run these tests, right-click the test project in Solution Explorer and choose Debug => Start New Instance.

Unit Testing in Visual Studio 2010 (part 1) - Creating unit tests

The Assert class in the Microsoft.VisualStudio.TestTools.UnitTesting namespace provides a set of static methods that provide you the conditions for your unit tests. Methods on the Assert class throw the AssertFailedException if the condition specified isn't true.

Microsoft ASP.NET 3.5 : AJAX-Enabled Web Services - Remote Calls via Page Methods

Page methods are simply public, static methods exposed by the code-behind class of a given page and decorated with the WebMethod attribute. The runtime engine for page methods and AJAX-enabled Web services is nearly the same.

Microsoft ASP.NET 3.5 : WCF Services for ASP.NET AJAX Applications

Foundation to build AJAX-callable services. Overall, the developer’s experience is mostly the same whether you use ASP.NET Web services or WCF services.

Mobile Game Networking Essentials : Network Programming and J2ME

Network programming in MIDlets is carried out using a portion of the MIDP API known as the Generic Connection Framework, or GCF.

Mobile Game Networking Essentials : Multiplayer Game Basics & Network Game Problems and Solutions

As mobile network speeds increase, this challenge will diminish, but developing efficient networking code is widely considered one of the most challenging aspects of game development, and even more so for mobile games.

Software Testing with Visual Studio Team System 2008 : Debug and running web test (part 2) - Running the test

If there are multiple requests in the test, the test result details window shows the result for each request. It shows the status of the request, as well as the details of the request, response, context, and the details of information gathered during the testing.

Software Testing with Visual Studio Team System 2008 : Debug and running web test (part 1) - Settings for .testrunconfig file

Most of the assembly built in .NET holds a configuration file associated to it to hold the settings required for the application. Similarly the test application creates its own configuration file with an extension .testrunconfig file.

Visual Studio Team System 2008 : Web test editor (part 3) - Toolbar properties

There are different options like adding a data source, set credentials, adding more requests recording, adding plug-ins to the test, generating code, parameterize the web servers, and creating the performance session for the test.

Visual Studio Team System 2008 : Web test editor (part 2) - Other request properties

Each request in the web test has its own properties and there may be many dependent requests for each main request. We can get and set some properties even at the dependent request level.

Visual Studio Team System 2008 : Web test editor (part 1) - Web test properties & Web test request properties

After completing all requests recording, click on the Stop option in the Web Recorder pane which will stop recording and close the browser window.

Build Mobile Websites and Apps for Smart Devices : Design for Mobile - Standing on the Shoulders of Giants

A big part of the success of the iPhone, and the iOS ecosystem as a whole, has been Apple’s focus on both the aesthetic and the experience of the platform and its applications.
