In my previous blog I showed the basics of using Type Converters in OpenAccess ORM. I even walked through creating a very basic type converter for storing an int as a varchar in SQL Server. The example converter was very basic, so in this blog I would like to take a look at something a little more practical. In this example I will create a converter that tells OpenAccess ORM to store the value of an Enum property using the enum value’s name. Out of the box OpenAccess will persist enum’s using the enum’s underlying type which by default is int. In...
When we conferred internally (in the beginning of the current quarter) on the update of the AJAX Car Rental sample application, we asked ourselves the substantial question: How can we make this example even more useful for the developers? And going through the functionality it incorporated, we made the important deduction: Add car location, to make the vehicles more easily discoverable all over the world
and Include localization to remove the language barrier for users that are not proficient in English. For the first part the most natural choice was to choose to integrate...
We have taken quite an adventure in chronicling the new Silverlight CRM demo and all the behind-the-scenes work that goes into making new demos for our site, but now we finally get to talk about the really fun stuff – UI. I know, I know, depending on what hat you are wearing at your company you may be thinking “Hey, I loved the previous posts on MEF (here and here) as well as what you were saying about the Repository Pattern, what’s all this UI business?” As it turns out, Telerik sells a wide range of UI components that are used...
This is part three of the RadChart for WinRT blog series. For more information please refer to the other parts of the series: Part one - A Prelude Part two - The Compilation Okay, we have already compiled our Windows Phone Chart under WinRT (refer to the previous post). The whole process went pretty straightforward and took less than an hour. Now, let’s move on with setting-up a demo project with a simple chart in it to verify the compilation and to check for some hidden exceptions. The steps are well familiar: File->New Project->Visual C#->Windows Metro Style->Application. Adding the reference to our freshly compiled...
While helping with the development of our Tasks application I stumbled upon a strange compiler error. There was a lambda expression that was compiling just fine before I touched the file with the lambda and after changing a line inside the body of the lambda, the project suddenly stopped compiling. The error was, that it could not find an adequate overload of the method that accepted the lambda in question as an argument. The cause turned out to be very interesting(for me at least) and I think it is worth sharing. Consider that you have a function with two overloads that both accept...
Q3 2011 release is getting close and we are eager to share some of the improvements that we have been working on lately. We have always been relying on your feedback to better shape our tools for your purposes. This time it is no different. RadPropertyGrid will get three highly requested features. The first feature will allow you to add custom items in the RadPropertyGrid by using RadPropertyStore. It is a collection of PropertyStoreItems which contain information that describes a property, its type, name, value, etc. When the RadPropertyStore is set to the SelectedObject property of the RadPropertyGrid, it displays these...
Back in late August/early September I spoke at the Rocky Mountain Ruby conference in Boulder, Colorado. My talk was about lessons learned dealing with large functional test suites over my career. For example, at a previous job I ran a team that got up to 9,000 Selenium tests scattered across roughly 850 test fixtures. I’ve had similar experiences working on other projects too. The talk was videotaped and is now up on the Confreaks video hosting site: Surviving Growing from Zero to 15,000 Selenium Tests. Yes, the talk’s title is wrong. I goofed when submitting it. The fundamentals I ...
A lot of people have posted tributes to Steve Jobs over the past week. I’ve seen him
called the CEO of
the Decade (something I agree with) and also
compared to Henry Ford (I sort of agree with). I’d like to call attention to four
lessons we can learn from Steve Jobs’ Apple, two positive and two negative. First
the good:
Apple avoided falling into the trap of the Innovator’s Dilemma
Apple avoided falling into the trap of the Innovator’s
Dilemma. In a nutshell, the Innovator’s Dilemma says the following (I am paraphrasing):
when you invent something, first you are trying to penetrate a new market and convince
people to buy your...
While working up a blog post today on creating a simple game with HTML5, I tested the app on my iPhone and found something quite interesting. It was ridiculously slow. You can check out the application here and see it’s performance on your mobile device. It appears to...
I’m at the John Wayne airport waiting on my flight back home from the StarWest conference. This was the first conference I’ve been at as a vendor – I’ve always been a visitor at the front of the booth, never behind it. I had to make some interesting mental changes, but it was a great experience once I got in the groove. Thursday morning I did a session called “Automation Isn’t Just Shiny Toys” where I discussed how to avoid some of the common pitfalls around automation: long running tests, brittle tests, tests which consume far too much time for ...
