Templating a XAML CheckBox to a thumbs-up/down control using Expression Blend

2012-01-30T11:43:00.001+02:00

The checkbox has been been around in the Graphical User Interface for as long as I can remember doing GUI – since the early 90’s I guess.

2012-01-25T10:40:00.001+02:00

IntroductionThis article illustrates how to implement security for a service method, in the context of custom authentication, confidentiality and integrity, using Message Contract. The message is packed with authentication information at the client side in the MessageHeader. The Service intercepts this message and validates the credibility of the consumer client. Besides, we will also check,

Symantec Admits Its Networks Were Hacked in 2006

2012-01-22T14:58:00.001+02:00

After having first claimed that the source code leaked by Indian hacking group Dharmaraja was not stolen through a breach of its networks, but possibly by compromising the networks of a third-party entity, Symantec backpedalled and announced that the code seems to have exfiltrated during a 2006 breach of its systems. Symantec spokesman Cris Paden has confirmed that unknown hackers have managed to

ESE C#/C++ Toolkit v1.2 for Microsoft Extensible Storage Engine (ESE) (ESE is the database engine that's been in the box since Windows 2000)

2012-01-22T13:33:00.001+02:00

Many developers are unaware that one of the most high performance, innovative and rich database engines available is built in as standard to all copies of Microsoft Windows. Microsoft have recently published the APIs and it is now available to use for free. Extensible Storage Engine (ESE) is part of a special subset of Windows technologies known as the Trusted Computing Base (TCB). The technology

Collections of components - an alternative

2012-01-22T13:32:00.001+02:00

In a project I work in we have a lot of places in our data model where an entity has some properties collections used just for displaying it to the customer, like list of company locations or source URLs for the document. We are not filtering/querying our data by these properties at all and we're pretty sure we wouldn't do that in the nearest projects lifetime. It may seem right to map these

Using Reflection To Create Mock Objects

2012-01-22T13:31:00.001+02:00

Well-established tools like Mockito and EasyMock offer a powerful range of features for defining and interacting with mock objects. I use both tools heavily in my unit tests, and would recommend them to anyone looking for a mocking framework. Sometimes, however, a real (i.e. non-proxied) collaborator is called for, or adding third-party libraries may not be an option. In most cases, a suitable

Silverlight 5 Security: Designed for the Intranet

2012-01-22T13:28:00.001+02:00

Silverlight’s role has always been poorly understood. Originally it was seen as something to compete with Flash, but Flash itself is being replaced by HTML5. It was also seen as a way of delivering cross-platform applications, but Apple’s policies concerning iOS made that a non-starter as well. Surprisingly it is thriving in areas that were supposed to be the domain of WPF such as internal

Setting a default value for C# Auto-implemented properties

2012-01-22T13:27:00.001+02:00

If you auto-implement a property, it would be handy to be able to set a default value. Indeed, there is the System.ComponentModel.DefaultValueAttribute which you can set, perfectly happily:[DefaultValue("-New Object-")] public string MyString { get; set; }[DefaultValue(240)]public int MyInt { get; set; }[DefaultValue(110)]public int EnvelopeHeight { get; set; }[DefaultValue(true)]public bool

Mocking Frameworks for .NET

2012-01-22T13:24:00.001+02:00

The four major competitors in the free/open source .NET mocking framework arena are microsoft .netNMock/NMock2, NMock3, Rhino Mocks and MOQ. NMock and NMock2 were actually built by different teams, but they kept the same design philosophy and are backwards compatible so they can be used almost interchangeably. If you're familiar with NMock/NMock2, you'll see that NMock3 is from the same gene pool

Швеция официально признала файлообмен религией

2012-01-22T13:23:00.001+02:00

Правительство Швеции официально признало Церковь копимизма — религию, центральным принципом которой является свободный обмен информацией. Копимисты (copy me) верят, что обмен информацией является священным и что ценность информации умножается, когда она распространяется.

20 Free Wireframe and Mockup Applications

2012-01-22T13:22:00.001+02:00

Mockup is the visual appearance of any website whereas the Wireframe deals with the contents and the functionality of the site. One of the easiest steps in building a website is by creating a mockup and of course both the concepts are quite essential for creating an effective website. The wireframes are very important for the layout and organizing the functional aspects of the web pages. The

Understanding the basic shape of Unix virtual memory management

2012-01-22T13:20:00.001+02:00

Although their implementations vary in detail, every modern Unix system (ie, everyone with mmap()) has some basic constraints that shape the general outline of their virtual memory system. While I'm talking about virtual memory statistics, it's worth running down this basic shape and what creates it. (I say this partly because I spend part of writing yesterday's entry sorting bits of this out in

I have talked before about the problem of accessing an uninitialized collection and presented a solution that allows us to see if the collection contains elements on the DB, and how many there are, without actually loading them. Now I have a general purpose solution for querying the collection on the DB. Here it is:public static IQueryable Query(this IEnumerable collection){ if (

Introducing Unity.WCF - providing easy IoC integration for your WCF services

2012-01-22T10:44:00.001+02:00

There are numerous blog posts available that explain how to hook up Unity with WCF. Unfortunately, many of these are incomplete, too basic or just plain wrong. Additionally, as far as I can tell, nobody has created a NuGet package to get you up and running as quickly as possible. This post introduces Unity.WCF, an open source NuGet package that (hopefully) just works in most situations, deals

Moving up in the world, from VirtualPC to Hyper-V? Here's how to keep your VM's happy.

2012-01-22T10:43:00.001+02:00

I was recently asked if I could help move a virtual machine that had been setup and running in VirtualPC and move it to run under Hyper-V.The answer is yes it can be done. Movement from Hyper-V to VirtualPC is not as easy (and many times not possible) but there are a number of blog posts on this topic already so I won’t cover that here. One of the reasons that it is easier to move from VirtualPC

passwdqc

2012-01-22T09:09:00.001+02:00

passwdqc is a password/passphrase strength checking and policy enforcement toolset, including an optional PAM module (pam_passwdqc), command-line programs (pwqcheck and pwqgen), and a library (libpasswdqc). On systems with PAM, pam_passwdqc is normally invoked on password changes by programs such as passwd(1). It is capable of checking password or passphrase strength, enforcing a policy, and
