Hi all

This one is for all those times you needed your Regular Expression Tool but you were using someone else’s computer or whatever and did not have it installed. Now you have this little online Silverlight Tool to help you with your regular expressions.

To use this tool do the following:

I am currently working on a SaveAs feature to some special file formats, those files are very very big. Before actually saving the file, I need to compute its anticipated size and compare it with the free disk space to see if there is enough storage for that operation. After searching a bit about how to get the free disk space, I came across the solution which uses the System.Management namespace. This namespace provides access to a rich set of management information about the system, devices, and applications instrumented to the WMI infrastructure. But, what the hell is WMI?

WMI is Windows Management Instrumentation and is part of the Windows operating system that provides management information and control. WMI provides extensive instrumentation to accomplish almost any management task and help us obtain information about our system. Applications and services can query for interesting management information such as how much free space is left on the disk, what is the current CPU utilization, which database a certain application is connected to, and much more, using classes from the System.Management namespace. Here is the MSDN page about the Windows Management Instrumentation.

Let me show you how to query the free disk space using WMI:

Have you been told that using those fancy JavaScript navigation menus is bad for your search rankings or that you will lose some visitors that have JavaScript turned off? This is a decision that all web developers face at one time or another. Do you use the cool looking menu which may help clean up large menus or do you cater to the largest audience possible? That can be a tough choice sometimes. Well, now there is no need to choose. In this article I will show you how to create a drop down navigation menu that is XHTML 1.0 Strict, CSS valid, opens external links in a new window, and is JavaScript free.

Keeping Backwards Compatibility In Mind

To keep things in perspective, in order to be 100% XHTML 1.0 Strict and support older, non-compliant browsers, a small amount of JavaScript is required. If you do not wish to support IE6 or older and don’t mind switching to a XHTML 1.0 Transitional doctype then this can be accomplished with 100% pure CSS and no JavaScript…

Hi all

Here is a small application I discovered lately which I just love!

This little application will give you the option of changing the colors of any Windows folders you want.

You can also Change how the folder actually looks and edit the Tooltip that will be displayed when the mouse hovers above it.

I have been wanting to write this series of articles for a long time. Over the years I have come across very bad code examples and I have always wanted to share them with you guys, kind of in the way of "Watch and DON’T learn" :).

Everything you are about to see in this series is based on my personal experience and completely real, so before we begin I have only one request:

Don’t try this at home!

Until a couple of years ago, most software applications were released in English. Unfortunately for us the developers, nowadays, many customers require that that the product they purchased, will be localized to a specific language (other than English). I know, for instance, that there is a European law which requires healthcare products to be localized to the European market (starting from 2009 or 2010). Because this article is about how to localize your application using string tables, I recommend you to first read about a free tool which helps you extract hard coded strings to string tables. Don’t go any further before you also read about how to generate public properties for string tables, you must read it.

Setting up a String Table

I assume that you already have some user interface which needs to be localized, I will demonstrate this process with…

Are you familiar with the following C# compilation error: “CS0104: ClassA is an ambiguous reference between Namespace1.ClassA and Namespace2.ClassA“? It happens when your program contains using directives for two namespaces and your code references a name that appears in both namespaces.

Lets work with a concrete example:

Overview

If you have ever looked at JavaScript as more than just a language for validation and “neat” effects then you know that, despite it’s seemingly simple design, it is a very powerful and complex language. All the frameworks and effects libraries that are being written, like jQuery and ExtJS, are a testament to this fact. Some of the frameworks give you tools for an object oriented (OO) approach to JavaScript. Being a C# programmer I pretty much only code in a OO manner and that just naturally translates into the JavaScript I write.

In this article we are going to take an introductory look at how OO JavaScript works. I am going to assume you are familiar with Object Oriented Programming (OOP) concepts such as encapsulation, inheritance, and polymorphism. If you aren’t familiar with these concepts or would like to refresh your memory you can take a look here. If this sounds like it might be complicated, don’t worry, it really isn’t and I’ll give you lots of example code to show you. Here we go.

Creating a class

The first thing we are going to look at is how to…

If you are a .NET developer, you should probably know the .NET Reflector which is a great tool for viewing, navigating and searching through the class hierarchies of .NET assemblies (even if you don’t have the code for them). I am using this tool a lot but here is something I only recently discovered: one can export an assembly and let the Reflector generate its source code. The output of this process is a directory with a project file and all of the source files.

Lets deep dive into this process. The first thing to do is to drag the assembly you’re interested in into the Reflector. I want to show my case on the XHTML sitemap validation tool dll, which can be downloaded from our Freebies page. The next step is to right click on this assembly and choose the Export menu option:

I am proud to say that the new theme is here for good
We would love to hear your thoughts and comments about it, and if something is not working the way it should please let us know.
Have a great week
