PartCover - Coverage of unexecuted methods

During the last weeks I received several emails pointing me to a potential issue in my tool ReportGenerator. The problem is that methods that have not been executed during a test run using PartCover, are marked as 'not visitable'.
I decided to take a closer look at the problem. In this post I will explain how ReportGenerator works and why it is not easy to create a workaround for the deficiency of PartCover.

.NET 4.0 - Performance of Task Parallel Library (TPL)

The upcoming .NET Framework 4.0 will contain the new Task Parallel Library (TPL). The TPL will be used by PLINQ, which is a parallel implementation of LINQ to Objects.
PLINQ makes it easier to take advantage of today's multicore CPUs, without caring about thread synchronization.
In this post I will do some benchmarks to get an impression of the TPL's performance, compared to current technologies.

WPF - Search and highlight text in DocumentViewer programmatically

The DocumentViewer is a great control for showing XPS documents in a WPF application. You can zoom and search the document, but the control does not provide a public API for its Find functionality. Microsoft is going to fix this in a future release, until then you can use the following workaround.

ASP.NET - Count feed subscribers without Feedburner

The most important advantage of Feedburner is the subscriber count. But Feedburner is not an option for everyone, since the address of your feed changes if you move it to Feedburner.
You could redirect requests to your feed to the new address, the disadvantage though is that when someone opens the URL in his browser the browser will show the new address.
In this post I will show an approach how you can get a subscriber count, without moving your feed to Feedburner.

VSTO - Speech recognition in Outlook Addin with .NET

In this article I will show how you could create an Outlook Addin that enables you to enter the recipients of an email by speech.
First we setup the speech recognition engine with the contacts from the address book. Then we listen to the relevant events to start and stop speech recognition automatically.

WPF - Animation of graph algorithms - Part 2

In the first part of this series I showed how to implement a data structure for graphs.
Now let's continue with the UI. The UI should be capable of creating graphs consisting of nodes and edges with some mouse clicks. Moreover it should be easy to execute previously created graph algorithms and to show their animations.

WPF - Animation of graph algorithms - Part 1

A few years ago I had to create some animations of graph algorithms. That meant two things: I had to implement algorithms like Dijkstra or Kruskal and then create a visual representation of the algorithm, so one could see what happens step by step.
The code was written in C++ using LEDA for the graphs data structure and AGD (now called OGDF) for visualization.

In this series I will describe how I implemented a tool for creating graph animations in .NET using WPF. This first part will discuss the underlying data structures. The second part will concentrate on the 3D stuff and the animations.

Deploying ClickOnce-application based on .NET 3.5 SP1 to IIS 6

Today I had to create a ClickOnce installation for a VSTO Word 2003 Addin. Until I finally managed to deploy it to an IIS 6 webserver, some problems had to be solved. First you have to configure your application in Visual Studio, afterwards you have to register some mime types in IIS.

ASP.NET MVC - How to protect your website against spam

When your use forms on your website, spammers will very soon be trying to inform your visitors about their "great" products. In this post I will show you how to protect your website by using a simple timestamp.

MSBuild - Code Coverage Analysis with PartCover and ReportGenerator

Ever since NCover has not been free any more, I use PartCover, which is available under the GNU General Public License (GPL).

In this post I will show how you could generate a nice 'Code Coverage Analysis' report by using ReportGenerator and how you could integrate PartCover and ReportGenerator in your MSBuild script.
