Native C++ implementation of the .NET Asynchronous Design Pattern using Windows I/O Completion Ports

Action filters are a powerful feature of ASP.NET MVC controllers that can help you build aspect-oriented Web solutions. In this issue we dive deeper into creating your own dynamic action filters.

Procedural programming is often seen as “old school,” outdated and useless in modern software design, but the design paradigm still shows up in a surprising number of places—including the compiler and MSBuild.

In the last issue, I introduced you to the basics of incorporating SQL Server Reporting Services into your ASP.NET MVC applications. In this issue, I’ll finish the series by illustrating how we can transfer data between the ASP.NET MVC context and the SSRS report context. In addition, I will also cover deployment issues such as authentication.

As developers are just getting used to ASP.NET MVC 2 and Visual Studio 2010, Microsoft has already planned and released a preview of the next version of ASP.NET. What started out as “just another option” for ASP.NET developers has become the programming style of choice for developers writing .NET applications for the web.

The HTML markup of a web page includes the page's textual content, semantic and styling information, and, typically, several references to external resources. External resources are content that is part of web page, but are separate from the web page's markup - things like images, style sheets, script files, Flash videos, and so on. When a browser requests a web page it starts by downloading its HTML. Next, it scans the downloaded HTML for external resources and starts downloading those.

A page with many external resources usually takes longer to completely load than a page with fewer external resources because there is an overhead associated with downloading each external resource. For starters, each external resource requires the browser to make an HTTP request to retrieve the resource. What's more, browsers have a limit as to how many HTTP requests they will make in parallel. For these reasons, a common technique for improving a page's load time is to consolidate external resources in a way to reduce the number of HTTP requests that must be made by the browser to load the page in its entirety.

This article examines the free and open-source ASP.NET Sprite and Image Optimization Framework, which is a project developed by Microsoft for improving a web page's load time by consolidating images into a sprite or by using inline, base-64 encoded images. In a nutshell, this framework makes it easy to implement practices that will improve the load time for a web page that displays several images.

The Chart Web control makes it easy to display a chart in an ASP.NET web page - simply drag the Chart control onto the page, set a few properties and either bind it to a data source control or write a few lines of code that get and bind the data of interest. When a page with a Chart control is visited by a user, the Chart control renders an <img> element on the page that displays the rendered chart.

The Chart control is great for displaying a chart on a web page, but what if a user wants to view that chart offline, or send the chart to a colleague? In an earlier installment, Programmatically Generating Chart Images, we examined a number of ways to generate the chart image programmatically. This technique is useful if you want to modify the chart image before displaying it (to, say, add a watermark) or if you want to send the chart to a recipient via email. This technique can also be used to allow the visitor to export the chart image into an alternative format.

This article shows how to let users export a chart from a web page to an alternative format. Specifically, we'll look at adding an "Export" button to the chart web page that, when clicked, exports the chart displayed in the web page to either an image file that can be downloaded or as a PDF file.
