We all know managed code can have memory leaks. You can find a good example here: A .NET memory leak you did not think about. Microsoft provides us with the CLR Profiler, an open source tool for analyzing the behavior of your managed application, which you can download here. It contains very good documentation about the different functions of the tool, however I still find it a bit hard to start with, so here is a simple step-by-step example of how to use it. After you finish downloadoing it , extract the files and open the directory. there you will find the manual, you can read it later… Navigate to CLRProfiler\Binaries\x86 (or x64) and run CLRProfiler.exe.

In my last post about 5 Firefox plugin’s any web developer needs I got hammered for not posting FireBug. I admit that FireBug is Amazing and I use it often, but anyone knows FireBug, so posting about it is a bit pointless. My aim was to shed some light on some less known plugins, and therefore today’s post will not include FireBug again

lets start then:

SVG (Scalable Vector Graphics) is an open W3C standard for graphics file format and Web development language based on XML. Those image are made up of lines, curves and other “smooth” elements so when you zoom in on a SVG it stays smooth (unlike GIF, JPEG, PNG). 

Imagine you can draw some of your user interface elements in a vector drawing application like: Adobe,   InkScape (free) or Skencil (free) and convert your work into WPF XAML or Silverlight XAML. ViewerSVG  (SVG to xaml converter) is your tool.

Master-Detail is a pattern for displaying details of a specific item selected from a list of items. In this post I’ll demonstrate how to use master-detail in WPF with two levels of objects, each displayed in a ComboBox and Data Binding to tie them together.

This is the fifth challenge in the series of programming job interview challenge. As usual, we’ll provide an answer to the previous challenge and give you a new challenge to keep you busy this week. Other then commenting the solution, I remind you that you can post the solution on your blog and let us know about it [...]

We all know the propertyGrid control, which provides a user interface for browsing the properties of an object. What about having a WPF propertyGrid? Well, yesterday I  noticed that there is a work in progress on an open source WPF property grid. Tomer Shamam announced in his blog Essential WPF that he accepted Microsoft Israel OPEN UP challenge (open source contest) and created a new project - WPF property grid. As he stated, it is currently only a Proof of concept and the interface and its usage may change in next releases. I think that its worth tracking…

The ServiceContainer, implementing the IServiceContainer Interface is used to store and retrieve services. it is used for Dependency Injection, a very important concept that allows separating independent components, and is widely discussed over the web. However, one drawback of this implementation is it does not work with .net  remoting…

I’m sure you’ve seen those nice interactive form validations on some Web 2.0 websites. The validation occurs while you’re typing your form input. For example, you’re typing your email in the email address field. You see a red “X” mark beside the field and when you’re finished typing your email address, a green check mark replaces the red “X” mark. What happens there is while you’re typing in your email address, the page communicates with the server to validate what you’re typing. When you finished typing your email address and the data you keyed in is valid, it passes the validation so it shows the green check mark without reloading the page. This is done using Ajax.

In this tutorial, you’re going to learn how to make this kind of interactive, Ajax-powered form validation (the same validation sample mentioned earlier). If you haven’t used Ajax before, don’t worry because I will show you how you can create Ajax-powered applications without worrying about the whole XmlHttpRequest process. If you can program with PHP and a little Javascript, you’re good to go. All you need is this handy little open-source Ajax toolkit called Sajax.

During the past couple of weeks we noticed that whenever we tweak our theme or change something in one of our posts, it causes some pages to become XHTML invalid. We came to think that you never know where it is going to hit you, so we sat down and created a small application which helps you keep all your pages XHTML valid. We checked it on our sitemap, and seems we have some HTML work to do :).

This application is written in WPF and is based on the .Net Framework 3.5.

It will allow you to validate you entire sitemap in one click. The validation is done through the W3C validation SOAP service, so you can trust it :).
