If you've ever tried to find a way to display an ESRI ShapeFile on a Virtual Earth map, you'll have probably noticed how little information there is on the Internet about how to accomplish this apparently arduous task. As a matter of fact, I needed to do exactly this while adding some collateral features to the software Serena and I are developing for our thesis, but after some Googling, I found that there was (and there still is) almost no useful information on how to achieve integration between...

In this article we'll see how easy it is to use Virtual Earth SDK to produce a simple mashup, using web services that provide information in JSON format. Live Demo - Source Code If you are not familiar with JSON or how to integrate JSON services in ASP.NET AJAX applications, you can take a look at my 3-part series of articles on JSON and ASP.NET AJAX here. First of all, we need to create a simple .aspx page, and add a ScriptManager to it. Then, we're going to reference the Virtual Earth API in the...

In this brief tutorial, we'll see how to leverage the ASP.NET AJAX infrastructure to call remote JSON web services from client script. In the first part, JSON and its main advantages will be introduced, in the second part, we'll see how to call a remote JSON web service from client script, with the use of a proxy service. We'll see how the ASP.NET AJAX framework makes calling local web services from client script a very easy task, and how tidily this is done. We'll also get introduced to some useful...

This is the third part of a series of articles on ASP.NET AJAX and JSON. If you haven't read part 1 and part 2 of this series, you are strongly advised to do so before going on to read this article. Let's take what we've seen so far on JSON and ASP.NET one step further, and discover how we can leverage the ASP.NET AJAX infastructure to make the managing of an AJAX application even sleeker. Now, let's imagine that we want to elaborate the JSON response returned from the web service before sending...

Now, after the very futile example which accompanied the introduction to JavaScript Object Notation in my last post (by the way, I forgot to mention that this is what the fancy acronym stands for, but I'm sure you already knew that), let's go straight to the fun part, and see how we can leverage the flexibility of JSON (and ASP.NET AJAX, of course) to achieve some less trivial result. When developing a web application, we often need to aggregate data from different sources. You might argue this is...

If you are a web developer, and you haven't been living under a rock for most of the past year, you must at least have heard of JSON. In the wake of the tremendous hype relating to everything even vaguely AJAX-related, JSON has climbed in record time the list of the top 10 technologies a web developer has to master. Let's make it clear from the start: JSON does deserve a top spot in such a list, if nothing else because it's the skeleton that keeps the whole AJAX paradigm on its feet. Even more so...

Hi, this is our first post. We finally decided to set up a blog where to write about our development experiences. We're both Computer Engineering students and .NET programmers. Our interest is mainly focused on Web Development, using ASP.NET, SQL Server, CSS, and (recently) Javascript. We're also interested in developing soft-computing models for risk prediction and analysis. We hope this weblog might contribute positively to the already thriving .NET developers' community!
