Programming Excel with VBA and .NET : Tasks in Visual Basic - Get Dates and Times
The Timer function is very handy when developing programs since it lets you see how long your code takes to run. When developing large or complex programs, it is pretty common to record the Timer value at the start of the process, then display the difference between that value and the current Timer when the task completes.
Programming Excel with VBA and .NET : Tasks in Visual Basic - Work with Text
Working with text is probably just as common as working with numbers in most programs. Visual Basic refers to text data as strings and it provides a set of string operators and functions just as it does for math.
A Technical Overview of the Mobile Web : THE TECHNICAL CHALLENGES OF MOBILE DEVICES (part 2)
A limited selection of device form factors tend to prevail in today's mobile market place. Some are more popular in certain parts of the world than others or among certain demographic groups, so a conscientious mobile web developer needs to be aware of all of them.
A Technical Overview of the Mobile Web : THE TECHNICAL CHALLENGES OF MOBILE DEVICES (part 1) - Physical Constraints
A limited selection of device form factors tend to prevail in today's mobile market place. Some are more popular in certain parts of the world than others or among certain demographic groups, so a conscientious mobile web developer needs to be aware of all of them.
Parallel Programming with Microsoft Visual Studio 2010 : Task Parallelism - Unhandled Exceptions in Tasks
Tasks are not immune to exceptions. An unhandled exception raised in a task is handled differently by the common language runtime (CLR) than a typical exception. Unhandled exceptions in tasks are not handled in the context of the task, but in the context of the joining thread.
Parallel Programming with Microsoft Visual Studio 2010 : Introduction to Parallel Tasks
Tasks run on threads. Threads are the engine of your application and represent running code. Understanding threads helps you understand tasks. This is important because some of the overhead associated with a task pertains to threads.
jQuery 1.3 : DOM Manipulation - Moving elements
With the back to top links, we created new elements and inserted them on the page. It's also possible to take elements from one place on the page and insert them into another place.

The Debugging Tools for Windows package is a freely available support package that contains a set of powerful debuggers and tools to help in the software troubleshooting process.
.NET Debugging : Managed Heap and Garbage Collection
The garbage collector in CLR 4.0 has undergone some really exciting changes/additions primarily in the area of exposing additional diagnostics and the addition of a new garbage collection mode called background garbage collection.
Context and Interception : Custom Component Services (part 3) - The Transaction Management Service
.NET 2.0 introduces an innovative transaction management service in the System.Transactions namespace. A transaction managed by System.Transactions is stored in the thread local storage and is called the ambient transaction.
Context and Interception : Custom Component Services (part 2) - The Logbook Service
One of the most beneficial steps you can take to achieve a robust application and faster time to market is to add a logging capability to your application. This section presents you with the logbook—a simple custom component service that allows you to automatically log method calls and exceptions.
Context and Interception : Custom Component Services (part 1) - Building a Custom Context Attribute & Installing a Custom Message Sink
A context-bound object shares a context with its client only if the client's context has all the services the component requires—in other words, if the context has the required properties.
Software Testing with Visual Studio Team System 2008 : Data-driven unit testing
This type of testing is useful in carrying out the same test multiple times with different input data from a data source. The data source can have any number of records or data row for which we wanted the test to be carried out.
Software Testing with Visual Studio Team System 2008 : Unit testing an ASP.NET application
Creating the unit test for an ASP.NET web site or application is similar to the one we created for the normal class library. The ASP.NET unit test is used for testing the methods or the business logic used for the ASP.NET site.
Microsoft Enterprise Library : Error Management Made Exceptionally Easy - Replacing an Exception & Logging an Exception
The configuration tool adds new exception handlers to the end of the handler chain by default. However, you will obviously want to log the details of the original exception rather than the new exception that replaces it.
Microsoft Enterprise Library : Error Management Made Exceptionally Easy - Diving in with a Simple Example
To provide this extra information, yet apply exception shielding, you may consider implementing configuration settings and custom code to allow administrators to specify when they need the additional information. However, this is exactly where the Exception Handling block comes in.
iPhone Programming : Connecting to the Network - Embedding a Web Browser in Your App
The UIWebView class allows you to embed web content inside your application. This class is the simplest but least flexible way of getting network content into your application.
iPhone Programming : Connecting to the Network - Detecting Network Status
One of the more common reasons for Apple to reject an application submitted for review is that the application doesn’t correctly notify the user when the application fails to access the network.
Parallel Programming with Microsoft Visual Studio 2010 : Introduction to Parallel Programming - Software Patterns
Parallel programming is not a new concept; it has been around for some time, although mostly on large or distributed systems. Parallel computing has more recently been available on personal computers with Threading Building Blocks (TBB), OpenMP, and other parallel solutions.
Parallel Programming with Microsoft Visual Studio 2010 : Introduction to Parallel Programming - Multicore Computing & Speedup
Speedup is the expected performance benefit from running an application on a multicore versus a single-core machine. When speedup is measured, single-core machine performance is the baseline.
Microsoft ASP.NET 3.5 : Web Services for ASP.NET AJAX Applications (part 2) - Consuming AJAX Web Services
A referenced ASP.NET AJAX Web service is exposed to the JavaScript code as a class with the same name as the server class, including namespace information.
Microsoft ASP.NET 3.5 : Web Services for ASP.NET AJAX Applications (part 1) - Remote Calls via Web Services
Web services provide a natural environment for hosting server-side code that needs to be called in response to a client action such as clicking a button. The set of Web methods in the service refers to pieces of code specific to the application.
Microsoft ASP.NET 3.5 : AJAX-Enabled Web Services - Implementing the AJAX Paradigm
According to the AJAX paradigm, Web applications work by exchanging data rather than pages with the Web server. An AJAX page sends a request with some input arguments and receives a response with some return values.
The Art of SEO : Measuring Search Traffic (part 2)
Action tracking is one step deeper than basic analytics. Rather than simply observing what pages are visited and how many unique sessions are logged, action tracking allows you to narrow down groups of visitors based on the actions they take on your site.
The Art of SEO : Measuring Search Traffic (part 1)
One of the basic data points of interest for an SEO practitioner is what search terms are bringing traffic to the website. This provides a quick way to see where the SEO campaign is going well and where it is not going so well.
Programming Excel with VBA and .NET : Tasks in Visual Basic - Do Math
Visual Basic provides built-in operators and functions that perform many of the same calculations that you are used to using from Excel formulas.
Programming Excel with VBA and .NET : Tasks in Visual Basic - Interact with Users
You can perform several broad categories of tasks with the Visual Basic language. Since we're talking about Visual Basic (not Excel), these tasks tend to be very general. More specific tasks are usually handled through Excel objects.
Context and Interception : The .NET Context
Every new app domain starts with a single context, called the default context. The default context provides no component services at all. The main reason why it exists is to help maintain a consistent programming model.
Context and Interception : .NET Component Services
.NET provides component services via call interception. To intercept a call, .NET must insert a proxy between the client and the object and do some pre- and post-call processing.
