Orange Frameworks

Thursday, January 25th, 2007

I’ve just opened small site, with my humble collection of libriaries. - framework.orangeflash.eu. Currently you can find there:

  • XML RPC: Allows you work with XML RPC API on server, for example you can work with blogs.
  • WordPress: WordPress API, build on XML RPC API, for WordPress based blogs.
  • Yahoo: Wrapper for original YahooSearchAPI, that allows more comfortable work, alogn with MXML component

Note: I didn’t make examples yet :)

Creating Own Meta Data in Flex

Saturday, January 20th, 2007

To create your own meta data, in Flex you have to set compiler option: -keep-as3-metadata

Here is small example -

Index.mxml:

Yahoo API Wrapper

Tuesday, January 16th, 2007

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:

  • title
  • summary
  • url
  • clickURL
  • dateModified
  • cache:
    • url
    • size

Flex Effects in Flash 8

Sunday, January 14th, 2007

I was porting mx.effects from Flex 2 Framework to ActionScript 2.0 recently, and here is some result. You can work with them just like in AS3, you can create effects and compositions (Parallel or Sequence).

Example.
Sources.

Note: I did not ported all classes, like Dissolve, Pixilate etc yet. And this is pre-alpha stage of porting, classes are not fully documenter, and only IEffect.play() method was tested so far.

Creating NanoRIA #2.1: .NET 3 Client

Tuesday, January 9th, 2007

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:

  • Start your WebService from Visual Web Developer, and remmember it’s url, you can check in the Task Bar.
  • Open Command Promt, and type: wsdl.exe HERE_IS_URL /out:Path\to\project\Service.cs

Now 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 - holds information about weather.
  • News control - with propaganda :D.
  • Flickr control - with images.

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).

Creating NanoRIA #1: Backend WebService

Sunday, January 7th, 2007

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:

  • RSS.NET framework for parsing RSS feeds.
  • FlickrNET framework for working with Flickr.com.
  • Microsoft WebDeveloper Express for developing and testing our work.
  • Web Services (similar tutorial with some info can be found in this blog .NET+Flex).
  • And some knowledge of C# (you can read this and this entries in my blog or review documentation of WebDeveloper).
  • And Flickr.com developer API key, which you can get after registration via your profile

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 flickr
  • GetWeather - Weather.

Let’s start.

Blend For ActionScript Coders #3: Simplest RSS reader.

Saturday, January 6th, 2007

Previous parts:

I think we are quite ready for our first application in Blend, that is RSS Reader, we also “meet” closer with XAML today.

Idea

Ok, our current RSS reader should be really simple, since this is our first time with layout in Blend. I say, we need one TextBox (something like TextInput\TextArea in Flex), one Button, and ListBox which will hold data from RSS feed. We Also have to create some custom class which will present every feed item in appropriate form, but this is another story.

I’ve just revamped my blog :D

  • Found new cool theme - Vistered Little

  • Edited Flath Text Formater:
    • Recompiled it for Flash 8, since this blog is about Flex and NET you should have FP9 by now.
    • Added “Copy Code” button to context menu.
    • Now FTF resizes nicely in all browsers (there were some issues with FF3\IE7).

Feel free to submit bugs.
