Text Tags and a Little CSS3 - Adding Style to Text with CSS3 (part 2) - Creating CSS3 classes and IDs

CSS3 classes and IDs are ways to extend a style to any element. For example, suppose you have a feature that you want to add to just some items such as a yellow highlight. If you define a div or a p element’s background color as yellow, all the text in either of those containers will be bright yellow — not what you want.

Text Tags and a Little CSS3 - Adding Style to Text with CSS3 (part 1) - Styling HTML5 elements with CSS3 properties

Most professional developers and designers prefer the CSS3 external style sheets because perfecting the desired style takes a lot of work. When you want to make a change to the design of a Web site, you can make changes to many pages that use an external style sheet, just by changing the one style sheet.

Visual Basic 2010 : Deploying Applications with ClickOnce - Registration-Free COM

One of the biggest benefits from ClickOnce is that users that do not have administrator permissions can install applications. By the way, there are situations in which an application is deployed together with some COM libraries but this can be a problem because such libraries need to be registered and a non-administrator user does not have the appropriate permissions for this.

Visual Basic 2010 : Deploying Applications with ClickOnce - Security Considerations, Programmatically Accessing ClickOnce

Depending on how an application is deployed or what system resources it needs to have access to, it will be considered under the Full Trust or the Partial Trust rules of .NET Framework Code Access Security.

Visual Basic 2010 : Deploying Applications with ClickOnce - Configuring ClickOnce

If you use third-party components, ensure that the producer made available a redistributable package that you can include in the deployment prerequisites. The .NET Framework will always be included as a prerequisite, because ClickOnce cannot predict if on the target machine the .NET Framework is already available.

Visual Basic 2010 : Deploying Applications with ClickOnce

To deploy an application with ClickOnce, you have three options: the Publish command in the Build menu, right-clicking the project in Solution Explorer, and selecting Publish or the Publish Now button in the ClickOnce configuration page within My Project.

ASP.NET 4 in VB 2010 : Site Maps (part 3) - Binding Portions of a Site Map, The SiteMap Class

The site map API is remarkably straightforward. To use it, you need to work with two classes from the System.Web namespace. The starting point is the SiteMap class, which provides the shared properties CurrentNode (the site map node representing the current page) and RootNode (the root site map node).

ASP.NET 4 in VB 2010 : Site Maps (part 2) - Binding an Ordinary Page to a Site Map, Binding a Master Page to a Site Map

Once you've defined the Web.sitemap file, you're ready to use it in a page. First, it's a good idea to make sure you've created all the pages that are listed in the site map file, even if you leave them blank. Otherwise, you'll have trouble testing whether the site map navigation actually works.

ASP.NET 4 in VB 2010 : Site Maps (part 1) - Defining a Site Map

The starting point in site map-based navigation is the site map provider. ASP.NET ships with a single site map provider, named XmlSiteMapProvider, which is able to retrieve site map information from an XML file. If you want to retrieve a site map from another location or in a custom format, you'll need to create your own site map provider or look for a third-party solution on the Web.

DirectX 10 Game Programming : Shaders and Effects - Vertex Shaders

Vertex shaders are the part of the pipeline where you are given control of every vertex that gets processed by the system. In previous versions of Direct3D, you had the option of using the fixed function pipeline, which had a built-in set of functionality that it used when processing vertices. Now with the latest Direct3D, you must do all the processing yourself.

DirectX 10 Game Programming : Shaders and Effects - High Level Shading Language

The High Level Shading Language (HLSL) is the programming language used to write shaders. Very similar in syntax and structure to C++, HLSL allows you to create small shader programs that are loaded onto the video hardware and executed. In previous versions of Direct3D, shaders were written in a language that was very much like assembler, which really restricted shader programming to those few people with a lot of graphics knowledge.

DirectX 10 Game Programming : Shaders and Effects - Effect Files

While using shaders individually is still possible with Direct3D10, you’ll find them extremely useful when grouped together into an effect. An effect is a simple way of packaging the needed vertex, pixel, and geometry shaders together to render objects in a particular way.

Programming Windows Services with Microsoft Visual Basic 2008 : Services and Polling - Updating the Service Events

We want to use the new service events properly by modifying the current events. This will allow us to reuse these structured literals quickly.

Programming Windows Services with Microsoft Visual Basic 2008 : Services and Polling - Adding a Module File, Adding New Polling Code

The service is going to continue to grow, so to help to keep things cleaner and more readable, let’s add a module file to the project. In the Solution Explorer, click the Tutorials project icon and select Add Module. Name the file modService.vb and click Add.

Microsoft Visual Studio 2010 : Using the Concurrency Visualizer (part 3) - The Cores View

The graph shows a timeline of the application applied to each processor. The y-axis shows the processors, and the x-axis shows the timeline, in microseconds. In this graph, each thread displays in a unique color. Gaps represent idle time on that processor core. If you point to a particular segment, the thread identifier will appear.

Microsoft Visual Studio 2010 : Using the Concurrency Visualizer (part 2) - CPU Utilization View, The Threads View

The central region is a graph, where the x-axis is a timeline in milliseconds. The y-axis presents mixed information. The top two rows are disk-read and disk-write activity. The remaining rows are threads.

Microsoft Visual Studio 2010 : Using the Concurrency Visualizer (part 1)

Performance analysis of a parallel application is more challenging than performance analysis of a sequential application. A parallel application has more moving parts, such as tasks, threads, the thread pool, and synchronization.

Microsoft Visual Studio 2010 : Reports and Debugging - Using the Parallel Stacks Window

The Parallel Stacks window displays a call stack from the perspective of parallel execution. Similar to the Threads and Call Stack windows, the Parallel Tasks and Parallel Stacks windows are frequently used together.

Microsoft Visual Studio 2010 : Reports and Debugging - Using the Parallel Tasks Window

Tasks, tasks, and more tasks! Parallel programs are built upon tasks. In the TPL, tasks are wrappers for parallel operations that are later queued and scheduled on threads in the .NET Framework 4 thread pool, which is the default scheduler. As such, tasks are the central ingredient of a parallel program; tasks replace threads as the basic unit of execution.

Microsoft Visual Studio 2010 : Debugging with Visual Studio 2010 (part 2) - Debugging Threads

Examine the bottom half of the preceding Call Stack window. You’ll see clear evidence of a task being created, queued, and finally invoked on a thread in the .NET Framework 4 thread pool.

Microsoft Visual Studio 2010 : Debugging with Visual Studio 2010 (part 1) - Live Debugging, Performing Post-Mortem Analysis

Post-mortem analysis involves debugging an application after execution has completed—a task that is most often accomplished with dumps. Managed debugging of dumps is an important new feature of Visual Studio 2010 and includes creating and opening managed dumps, which is extremely important in a production environment in which live debugging is not an option.

.NET Components : Serialization and Class Hierarchies (part 2) - Manual Base-Class Serialization

Combining class hierarchies and serialization, whether fully automatic or custom, is straightforward: all classes either use only the Serializable attribute, or use the attribute and also implement ISerializable.

.NET Components : Serialization and Class Hierarchies (part 1) - Custom Serialization and Base Classes

If any of the classes in the hierarchy implements ISerializable, there are a few design guidelines you have to follow to allow subclasses to provide their own custom serialization and to correctly manage the custom serialization of the base classes

.NET Components : Custom Serialization (part 2) - Constraining Serialization

Presently, .NET does not provide a mechanism for constraining a generic type parameter to be serializable. However, there are three workarounds to guarantee deterministic serialization behavior.

.NET Components : Custom Serialization (part 1) - The ISerializable Interface, Implementing ISerializable

Both GetObjectData( ) and the custom deserialization constructor accept a parameter of type SerializationInfo called info. SerializationInfo provides methods for getting or adding field values.

.NET Components : Serialization and Streams - Serializing Multiple Objects

A noteworthy aspect of using streams in serialization is that there are no limits to the number of objects or types you can serialize into a stream. It all depends on the way you manage the stream and the sequence in which you write and read the information.

Microsoft ASP.NET 3.5 : Writing HTTP Handlers (part 5) - Advanced HTTP Handler Programming

HTTP handlers are not a tool for everybody. They serve a very neat purpose: changing the way a particular resource, or set of resources, is served to the user. You can use handlers to filter out resources based on runtime conditions or to apply any form of additional logic to the retrieval of traditional resources such as pages and images.

Microsoft ASP.NET 3.5 : Writing HTTP Handlers (part 4) - Serving Images More Effectively

In many cases, the URL points to a static resource such as a GIF or JPEG file. In this case, the Web server takes the request upon itself and serves it without invoking external components.

Microsoft ASP.NET 3.5 : Writing HTTP Handlers (part 3) - The Picture Viewer Handler

To speed up processing, IIS claims the right of personally serving some resources that typically form a Web application without going down to a particular ISAPI extension.

Microsoft ASP.NET 3.5 : Writing HTTP Handlers (part 2) - An HTTP Handler for Quick Data Reports

The idea is to build an HTTP handler for custom .sqlx resources. A SQLX file is an XML document that expresses the statements for one or more SQL queries. The handler grabs the information about the query, executes it, and finally returns the result set formatted as a grid.
