Example: Controlling randomizer using code contracts

published 1111 days, 20 hours, 23 minutes ago posted by

gpeipman 1112 days, 19 hours, 15 minutes ago

One cool addition to Visual Studio 2010 is support for code contracts. Code contracts make sure that all conditions under what method is supposed to run correctly are met. Those who are familiar with unit tests will find code contracts easy to use. In this posting I will show you simple example about static contract checking (example solution is included). (more)

gpeipman 1140 days, 8 hours, 20 minutes ago

ASP.NET 2.0 has no support for using conditionals in data binding expressions but it will change in ASP.NET 4.0. In this posting I will show you how to implement Iif() function for ASP.NET 2.0 and how ASP.NET 4.0 solves this problem smoothly without any code. (more)

Windows Phone 7 development: reading RSS feeds

published 1146 days, 1 hour, 16 minutes ago posted by

gpeipman 1147 days, 18 hours, 48 minutes ago

One limitation on Windows Phone 7 is related to System.Net namespace classes. There is no convenient way to read data from web. There is no WebClient class. There is no GetResponse() method – we have to do it all asynchronously because compact framework has limited set of classes we can use in our applications to communicate with internet. In this posting I will show you how to read RSS-feeds on Windows Phone 7. (more)

Entity Framework 4.0: Creating objects of correct type when using lazy loading

published 1153 days, 18 hours, 34 minutes ago posted by

gpeipman 1155 days, 7 hours, 26 minutes ago

In my posting about Entity Framework 4.0 and POCOs I introduced lazy loading in EF applications. EF uses proxy classes for lazy loading and this means we have new types in that come and go dynamically in runtime. We don’t have these types available when we write code but we cannot forget that EF may expect us to use dynamically generated types. In this posting I will give you simple hint how to use correct types in your code. (more)

Advanced donut caching: using dynamically loaded controls

published 1158 days, 19 hours, 46 minutes ago posted by

gpeipman 1159 days, 6 hours, 36 minutes ago

Yesterday I solved one caching problem with local community portal. I enabled output cache on SharePoint Server 2007 to make site faster. Although caching works fine I needed to do some additional work because there are some controls that show different content to different users. In this example I will show you how to use “donut caching” with user controls – powerful way to drive some content around cache. (more)

Simple pager for ASP.NET MVC

posted by

gpeipman 1182 days, 21 hours, 45 minutes ago

I needed simple pager for one of my ASP.NET MVC projects. I mean really simple pager – no new types my code should be aware of, no any other chemistry I don’t really need in early stages. As ASP.NET MVC has nothing to offer I wrote my own really simple pager implementation. Here is what I did. (more)

I start writing series of blog posting about code metrics. I plan to introduce different metrics and explain their meaning. Also I plan to introduce tools you can use to measure those metrics. Where possible I will introduce you how to use one or another metric. The first metric is the simplest one and it is called Lines of Code (LoC). (more)

Why is my page redirecting me back to front page although it gets all the data it requires? I was going out of my mind when exploring the problem in one system but this time there was really simple answer: you cannot fully trust the code written by n00bs. Okay, here is my story. (more)
