New web site launched

I’ve written a few posts about working with the eBay API, and I’ve been using it a bit as a part-time seller, so I decided to make the tool I wrote available to anyone. The site is called Listing Trends (www.listingtrends.com), and it allows potential sellers to research what is currently hot on eBay. You can drill into individual categories and view the tops results by highest number of watchers, bidders, or the highest price. There are also pages that show listings with a low Buy-It-Now, or listings ......

Using cascading ListBoxes to display hierarchical data in Windows 8

When you're dealing with hierarchical data (a tree-like data format such as folders that have sub-folders that have subfolders, etc.) you have to come up with an organized way of displaying it. You could create a tree view, similar to how Windows Explorer displays folders, but I wanted to try something different in Windows 8 - cascading ListBoxes. The user selects an items in a ListBox, and then a new ListBox appears to the right showing the sub-categories. This continues as long as there's data ......

Retrieving a list of eBay categories in a .Net 4.5 Windows Store App

Previously I wrote a post on how to get the eBay category list using their .Net SDK. I wanted to try doing the same thing in a Windows Store App for Windows 8 using Visual Studio 2012, but quickly ran into compatibility problems since the DLLs are compiled for .Net 2.0. I could have either changed the targetted framework, or attempted to re-write the DLLs, but neither sounded particularly exciting, so I simply decided to fall back to using a simple URL request and parsing it via Linq to XML. As mentioned ......

Speeding up ForEach loops with parallel programming - Task Parallel Library

If you're working with large chunks of data, eventually you'll probably use a foreach loop to iterate through an enumerable data source and execute the same actions on each item (for example, do something to every DataRow in a DataSet). With the new Task Parallel Library (TPL) in .Net 4 you can execute these loops in parallel for a noticeable improvement in speed. .Net has had support for parallel programming since the 1.0 version, but the developer had to do (sometimes...) extensive work to create ......

Review of InRule v 4.0 Business Rule Authoring system

I’ve worked with the BizTalk Rule Engine and various rule systems using Windows Workflow Foundation with varying degrees of success, so I was interested in seeing InRule’s solution, billed as “The Premier .NET Solution for Authoring, Managing and Executing Business Rules”.

Product Components of InRule InRule has multiple components for authoring, storing and executing rules, each of which can ......
