I’ve just opened small site, with my humble collection of libriaries. - framework.orangeflash.eu. Currently you can find there:
Note: I didn’t make examples yet :)
To be honest I don’t like Yahoo Search ActionScript 3.0 API, it doesn’t support all data types, for example in order to get thumbnail url, from image search request, you have to parse xml manualy… Also it does not compile with strict-mode compiler option.
So I’ve decided to create my own wrapper for Yahoo API. Here is another pre alpha version (damn, I have too many alphas :) ).
My wrapper has new event object - YahooEvent, and different ValueObjects for different search types. for example Web VO has following fields:
In the previous tutorial we’ve created very small Web Service, which provides us with news, images and weather. Now we will create client to our Web Service in Microsoft Blend
So lets start Blend and C# Express, and create new project called “MiniRIA”, and lets start to develop!
But before we’ll actualy start to develop, we need WebService proxy class that call remote operations on our server. We’ll do this same way we did with GlobalWeather service:
wsdl.exe HERE_IS_URL /out:Path\to\project\Service.csNow let’s think a bit (yeah we have to do this stuff sometimes), since I’m using Windows Vista I really miss old Windows XP window layout, do you remmember blue panel with expanding toolboxes on your left, and content of a folder on your right? We’ll do similar layout in our application. On left side we’ll place weather and media information, and news on right. So we have to create 3 main UI Controls:
Weather control will hold some Labels and TextBoxes controls, News and Flickr will contain ListBox instance, which will be filled with content (images for Flickr and news for News).

This is first tutorial in a series of “Creating NanoRIA”, in these tutoriales we will discuss creation of Web Service and small range of client. Today we’ll talk about server-side, than in the next tutorials we’ll create WPF client, Flex and Flash Lite clients, so potential end-users will be able to run our app on: Windows, Mac OS, Brew, SymbianOS and WindowsMobile.
Introduction
Lets pretend that we work for some company, and they want widely accessible application (Macs, Windows, Mobile devices etc.) which will let users to get access to news, some media data (photos), and weather information. Of course we won’t create that big stuff, we’ll emulate these functions, we will read news from EuroNews.net and BBC.com, then we pull some images from Flickr.com and weather from webservicex.net, but we still can pretend ;).
For this tutorial you’ll need:
Planning
Ok so we’ve agreed that we pretend that we own Flickr, BBC and Euronews (cool isn’t it? :D), lets see what we have.
We have:
Quite nice, so we have to make these data avaliable in appropriate form for users, for news I suggest that we gather em all in one place, and than sort them by date, and since downloading a lot of news could be a problem for mobile users, we have to define two ways of getting news: for desktop computers and for mobile users. Then we will pass bunch of links to flickr photos, and information about current weather.
In order to do this, we will create a series of Value Objects (also known as DTO), which will be sent by our server to client.
Our Web Service will have 4 methods:
GetNews - Retrieving latest news.GetNewsLite - Same but for mobiles.GetPhotos - Photos from flickrGetWeather - Weather.Let’s start.

Well this is pre-alpha version of my first .NET 3.0 application, dont kick me please. Currently this is really-simple-OrangeFlash-rss reader, that means, that it can read only this feed, but dont worry this is temporary.
Download application
Download sources
You will need NET 3.0 runtime and Expression Interactive Designer.
Yesterday I wrote about Yahoo Flash Developer Center, and posted simple example example with web search using Yahoo API, now I present Yahoo Spell Checker, source files avaliable here
This works slowly, but I have an idea. This application should have some kind of local dictionary, which would filter words for checking, for example “I”, “the”, “hello”, “flash” and other commonly used words should not be checked, this should speed up the proccess.
Yahoo lunched Flash Developer Center.
With Search API we can:
For this tutorial you will need:
Adobe Flex Builder
Microsoft Visual Web Developer Express
Also need to know what is WSDL, SOAP (you can read about them at http://www.wikipedia.org).
Part I: Creating of the Web Service in Visual Web Developer Express
To be honest I love this programm, this programm designed especialy for lazy guys like me, we dont need to install, setup, download different parts and plugins, register or do other actions to test your projects. This programm will do everything for you :D. This is just the right thing we need for my newbie level of WebService developing.
We will create service which should give us rates for the Adobi, Applo and Mecrosoft shares (we will generate them of course). For this purpose we will create OrangeStocks class, which will be WebService itself, and StockData class, which should “collect” data about rates.
