In a recent project a had to create an updatepanel in ASP.NET. The creation of the panel was not the problem, the panel had a couple of textboxes and when the user 'tabs' between them, then a server-call was done to validate the input through a service.It was an address-validation control. User inputs his address and it is checked on the fly against a service.The problem was that when the user

Gents,Recently I had a problem at hands, I wanted to run run the RuleEngine from Workflow Foundation outside WF.It is possible and easy to run the RuleEngine outside of WF, but the possibility to track which rules were executed was skipped, as far as I found and saw in the API.You can track executed rules when you run the workflow runtime itself and attach a TrackingService, but it came out to

It's been a while since I've posted a new topic, so I was thinking on what topic to post about on my blog. After a while of hard thinking and sleepless nights (just kidding) it stroked me... The idea entered my mind :)I while ago I stumbled on an article somewhere regarding HTM (Hierarchical Temporal Memory)... 'What?' you may think? Well, it's an algorithm in A.I. invented by numenta if I'm not

Since I've always been interested in automatisation (domotics) and because I saw the introduction of a new module regarding embedded programming of GHI Electronics, I've bought a development board that makes it able to program through the .NET Micro Framework.In the beginning I even had never heard of .NET Micro Framework, didn't know that it existed.I got really excited because this board

A problem that's pretty common is to determine whether an object has been changed, how do we know an object is changed?You can use for example datasets; datasets keep track of changes, and can update only changed rows.But in most of the projects that I had to work on, datasets weren't used, or as less as possible, they used their own domain model for storing and transmitting data from point a to

Howdy,Wouldn't it be easy to call in .NET a PHP function, and retrieve an answer in the form of an .NET object?I've looked around on the net and I haven't found a library that does such a thing.Because I've made a site in PHP for managing kittens and nests (cat-site) etc, where users can add stuff as they want, the client requested to manage the clients and the nests etc, which is pretty logical,

SamI've adapted the code so that it can also clone LINQ entities (EntitySet etc)The code is not yet in a final stage but it is becoming more and more stable as I refine the code, so, if you have comments or suggestions, please let me know...I've added in this version:Deep cloning until 1 level (more level's, i'm not

Howdy, If you've read the rest of my blog, then you'll have noticed that I have another post that addresses cloning of objects using IL (Intermediate Language) If you haven't, then you can find the post 'Object cloning using IL in C#'. The reason I published this post is because the code in my previous post (mentioned above) makes a shallow copy of an object. It copies only references

Howdy folks,With this entry I would like to show the possibilities of DSL.For those who don't know DSL, DSL as in Domain Specific Language,is a modeling tool for modeling problems in an organization for example.An example that everybody who's familiar with Visual Studio Standard Edition or higher knows is the Class Designer. It's a graphical tool within VS that allows you to model your classes,

This subject is inspired on a session I followed on the TechDays 2008, that addressed the fact that IL (Intermediate Language) can be used to clone objects, among other things, and that it's not evil at all, and it can be pretty performant also. You only have to see that you don't overuse it tho, because otherwise the readability of your code is reduced, which is not a good thing for

Since I'm bitten by the A.I. microbe, I'm experimenting with all kinds of Neural Networks and Genetic Algorithms. Therefore I created a little simulator to visualize the networks, for experimenting with it. For the visualizing I used GLEE , a 'new' framework from Microsoft Research that's able to draw flowcharts, hierarchical diagrams, ... I created the tool so that I can

  While developing an application for my company, I had to use a PropertyGrid (default WinForms-usercontrol). The problem was the localization of this grid.The client wanted to localize the categories, property-names,  enum selection values and the descriptions. So I did some research and developed a couple of handy classes that can do the job. The first step was to create some resx resource

Howdy,This class is something I distilled from a C library while translating a piece of code that I needed for doing face detection, I ran into this handy class for reading configuration files. Normally you use the ConfigurationManager of .NET to read your app.config files etc..., but this is a handy class to parse files or make very simple flat-files that contain some configuration info.If you

Because i need conversions from and to pointers for arrays and structures, i made a little class that can to the job for me.The most common problem is that all examples that I've found, copies arrays, or fills them up. But no examples of getting a pointer back into an array, without giving the startindex and count of the elements.I made it possible to convert an array to pointer and visa versa,

With this article i would like to demostrate the Color SOM (Self Organizing Map)The basics of this application comes to creating and training a neural network that groups colors with eachother.The neural network itself is a SOM (Self Organizing Map) or SON (Self Organizing Network) map. It has 3 input nodes, and in this example a 40 by 40 matrix of output nodes. In this network there are no '

This class is meant for variables in C# that must be readonly.Offcourse you can use the "readonly" keyword of C#, but you can only initialize it in the constructor of a type.This little class makes it possible to initialize it in the constructor and assign it once somewhere else.
