Modeling people and organizations: Class Party
Classes for people and organizations are often modeled incorrectly in object models. These faults cause heavy implementation problems. In this posting I will analyze some legacy models, introduce class Party as generalization of people and organizations and provide some implementation details. Information here is based on my own experience, like always.

ASP.NET MVC Calendar component
I am writing simple ASP.NET MVC system that I plan to publish with source code pretty soon. I needed some simple calendar component that doesn’t require ASP.NET server-side form to work.

I updated it and here is the source and binary downloads for Visual Studio 2008 and ASP.NET MVC 1.0.

In this posting I describe how I prepare my gallery application for automated testing. As a first thing I plan to write some unit tests because some of my classes have now logic to be tested. The other thing is database that is living outside my Visual Studio solution. Let’s make now first steps in my gallery code packaging.

ExpectedException attribute in Visual Studio 2008 and Visual Studio 2010
Today I tried to write my first unit tests under Visual Studio 2010. Just to see if Visual Studio testing system can now also be used for unit tests. Visual Studio 2008 had some annoying problems with test and I preferred to use nUnit instead. Visual Studio 2010 brings some good news – tests work. Take a look at my example.

MyGallery2010
MyGallery2010 is my simple photo gallery system built on Visual Studio 2010 and .Net Framework 4.0 technologies. I don't have currently any public release of gallery but I hope that one day it is ready to release. Until this day you find here references to my postings where MyGallery2010 is mentioned. Those postings illustrate pretty well how I am building the gallery, how I design it and what decisions I make.

SharePoint: Creating HttpHandler for user profile images
I have custom authentication and user profiles solution where user profiles are stored in list. This list is directly accessible only to administrators. Users can register to site and modify their profiles through special pages that run profile operations under elevated privileges. Users have three versions of their avatar: 64x64, 32x32 and 16x16. These avatars are saved as user profile attachments when user uploads his or her avatar. Because avatars are used at almost every page in portal I wrote IHttpHandler that provides avatars based on user profile ID.

Reordering invoice lines using jqGrid and TableDND extension
In one of my ASP.NET MVC applications I needed flexible interface for inserting invoice lines. Sometimes invoice lines are inserted in incorrect order and it saves accountants some time if they are able to change the order of invoice lines quickly. In my application I used jqGrid with TableDND extension. Here’s how I got it work.

What do you think of my ASP.NET MVC gallery layouts?
To try out Visual Studio 2010 and .Net Framework 4.0 I decided to write simple gallery application based on ASP.NET MVC Framework. In this posting I show you my very first layouts I created for gallery. These layouts are modifications of ASP.NET MVC default blue-white-black layouts. I also added some photos of my first layout drafts. My question is – what do you think about my first draft-level layouts (I am not designer)?

Entity Framework 4.0: On the way to Composite Pattern
In my last posting about Entity Framework 4.0, Entity Framework 4.0: POCOs and table-per-type inheritance mapping, I made first generalization to my photo gallery model. I introduced GalleryItem class that is base class for all that can be added to gallery: new albums, photos and maybe videos too. Although everything works as expected my model needs some modifications because it is not very foolproof.

Entity Framework 4.0: How to use POCOs
Entity Framework 4.0 will provide us with POCO support. That’s good because Entity Framework supports more inheritance mapping strategies than LINQ To SQL but currently it doesn’t support POCOs. To try out Visual Studio 2010 and ASP.NET 4.0 new features I started writing simple photo gallery web application. Today I got my first simple POCOs work with Entity Framework 4.0.

ASP.NET MVC: How to combine scripts and other resources
ASP.NET pages that use AJAX components make usually many requests to server per one page to load all required JavaScript and CSS files. Connections, like all other real time resources, are most expensive to create and keep. If we can somehow decrease the number of requests per page load then we need less server resources for same amount of users. For ASP.NET forms we can use script combining, for ASP.NET MVC applications we can use ASP.NET MVC Client-side Resource Combine.
