DevExpress Complexity (Maintenance & Cyclomatic

I have been using DecExpress’s CodeRush tools a lot recently. One of the many great features COdeRush gives you is inline Cyclomatic and Maintenance complexity scores of your classes and methods.

The challenge is to remember how those scores rank so you know when you should start refactoring your methods. I found a great post here that I wanted to move over to my own blog just to make sure I could find it again and have it handy. There is also a PDF reference to all this info.

Here is my summary of the key things (in case the other post goes away):

Cyclomatic Complexity

Probably the simplest measure of complexity. CC is the number of decision points for a method plus one. It also happens to represent the minimum number of test cases needed to travel through all branches of a method.

Maintenance Complexity

The purpose of Maintenance Complexity is to give you a picture of how much code you have in a given member.

Uniting Testing Expression Predicate with Moq

I recently was setting up a repository in a project with an interface on all repositories that took a predicate. As part of this I needed to mock out this call so I could unit test my code. The vast majority of samples out there for mocking an expression predicate just is It.IsAny<> which is not very helpful as it does not test anything other then verify it got a predicate. What if you actually want to test that you got a certain predicate though? It is actually pretty easy to do but not very straight forward. Here is what you do for the It.IsAny<> approach in case someone is looking for that. this .bindingRepository.Setup(c => c.Get(It.IsAny<Expression<Func<UserBinding, bool >>>())) .Returns( new List<UserBinding>() { defaultBinding }.AsQueryable()); This example just says to always return a collection of UserBindings that contain “defaultBinding” (which is an object I setup previously). Here is what it looks like when you want to pass in an exp

Experience Profile Anonymous, Unknown and Known contacts

When you first get started with Sitecore's experience profile the reporting for contacts can cause a little confusion. There are 3 terms that are thrown around, 1) Anonymous 2) Unknown 3) Known. When you read the docs they can bleed into each other a little. First, have a read through the Sitecore tracking documentation to get a feel for what Sitecore is trying to do. There are a couple key things here to first understand: Unless you call " IdentifyAs() " for request the contact is always anonymous. Tracking of anonymous contacts is off by default. Even if you call "IdentifyAs()" if you don't set facet values for the contact (like first name and email) the contact will still show up in your experience profile as "unknown" (because it has no facet data to display). Enabled Anonymous contacts Notice in the picture I have two contacts marked in a red box. Those are my "known" contacts that I called "IdentifyAs"

Excel XIRR and C#

I have spend that last couple days trying to figure out how to run and Excel XIRR function in a C# application. This process has been more painful that I thought it would have been when started. To save others (or myself the pain in the future if I have to do it again) I thought I would right a post about this (as post about XIRR in C# have been hard to come by). Lets start with the easy part first. In order to make this call you need to use the Microsoft.Office.Interop.Excel dll. When you use this dll take note of what version of the dll you are using. If you are using a version less then 12 (at the time of this writing 12 was the highest version) you will not have an XIRR function call. This does not mean you cannot still do XIRR though. As of version 12 (a.k.a Office 2007) the XIRR function is a built in function to Excel. Prior version need an add-in to use this function. Even if you have version 12 of the interop though it does not mean you will be able to use the function. The

Security Config in IIS Express

I have gotten tired of always having to look this up or remember where it is at. That means it is time to post to my blog so I can find it easier and hopefully others can too. If you are having issues with IIS Express authentication errors (like the Unauthorized 401.2 error I always get) here is some help. I can never remember what the last setting was I had IIS Express set to for authorization. To change IIS Express for windows auth or anonymous auth you want to work with the applicationhost.config file. It can be found here …Documents\IISExpress\config. You want to change the settings in the following area of the config file. < authentication > < anonymousAuthentication enabled ="true" userName ="" /> < basicAuthentication enabled ="false" /> < clientCertificateMappingAuthentication enabled ="false" /> < digestAuthentication enabled ="false" />

Anatomy of Sitecore Business Rule - Field Syntax

In the previous post, I talked about the general anatomy of Sitecore Business Rules . In this post, we will dig more into the rule itself and how you can set one up. In the previous post, I mentioned the "special syntax" a rule has in the "text" field. Let's dig more into what this is. This is broken into 4 parameters, not all of which are required. Property to set , defines the public property of the class where we want to assign the value coming from the content author input Operator or Macro , the operator we want to use to evaluate the condition. In this case, this will be a string comparison operation Additional Parameters , this parameter will depend on the type of macro that we use, this could be a default text value if we are using the default macro, it could be a default start path if we’re using the Tree macro ( root=/sitecore/content/myitem ) – think of it like setting a field source when we’re building a template in Sitecore.
