微软的ASP.NET版的AJAX框架已经在今年的PDC上发布其预览版。其主页在http://atlas.asp.net/
欢迎在这个帖子回复Atlas的其他相关的信息 :-)

AJAX绝对是个有用的技术，准备好升级吧!

其实把asp.net现有的优势和ajax无缝结合起来不是更好.
编码的方式不需要做改动.
现在正在正在弄这个。

呵呵，刚开始接触，感觉不错，
但可能js要写的比较多了。

>>> 客户端数据绑定区域或者控件的更新问题
实际上使用js脚本进行更新的

>>> 大型数据的回传的速度和稳定性的问题
本质上和IE下载web的html页面没有本质区别

>>> 传输数据的编码问题
同上

>>> 服务端在获取数据服务器数据并回传的过程中能否异步，以及如何检测传输的状态
都可以吧，xmlhttp已经内置支持这些功能了

这技术好是好，但是我还是有些问题不是很理解，例如：
1.客户端数据绑定区域或者控件的更新问题。
2.大型数据的回传的速度和稳定性的问题。
3.传输数据的编码问题。
4.服务端在获取数据服务器数据并回传的过程中能否异步，以及如何检测传输的状态。

哪位高人能帮我解答，不甚感激。

ajax.net我用过
但是最后还是搞atlas来拉
因为我认为用ajax.net只是个过度的问题
等MS的atlas 正式版一出大家我想都去用他了
现在正再高atlas
再翻译一点文档

前日从Scott的Blog上看到有人发现了ATLAS应用后页面数据重复提交的问题，不知在正式版出来时会不会解决这问题。

Ajax是一种技术, 也有一定的应用场合.

而且Ajax Professinal for .net framework它的思想和设计架构是很不错的
个人对Ajax的评价还是不错的. 不过至于微软ASP.NET上的Ajax结合成什么样子, 就不知道了.

不寄太大期望

好像无刷新的东西在安全性方面不是太好。

Learn iPhone and iPad Cocos2D Game Development provides a rock-solid introduction to the cocos2d iPhone game engine and related tools. It focuses on the process of creating several games made entirely with cocos2d and little to no iPhone SDK and OpenGL code. By creating 2-3 sample games over the course of the book, you’ll learn key concepts of the cocos2d game engine and relevant tools like Zwoptex (TextureAtlas), ParticleDesigner (Particle Effects), and others. The example games are modeled after popular App Store games so that they are relevant, recognizable, and immediately fun and inspiring. The games increase in complexity and highlight common recurring cocos2d beginner questions. As you move along, you’ll learn about possible stumbling blocks and how to navigate them successfully. As you move from beginning to advanced, you’ll encounter general game programming wisdom, tips for performance improvement, as well as pointers to alternative implementations and further reading. It is assumed that the reader has previous programming knowledge but not necessarily with Objective-C. Related topics such as Xcode, Objective-C, the iPhone SDK, and OpenGL are only discussed where absolutely necessary.

Create compelling 2D games with Learn cocos2d 2: Game Development with iOS. This book shows you how to use the powerful new cocos2d, version 2 game engine to develop games for iPhone and iPad with tilemaps, virtual joypads, Game Center, and more. It teaches you: The process and best practices of mobile game development, including sprite batching, texture atlases, parallax scrolling, touch and accelerometer input. How to enhance your games using the Box2D and Chipmunk physics engines and other cocos2d-related tools and libraries. How to add UIKit views to cocos2d and how to add cocos2d to UIKit apps. The ins and outs of the Kobold2D development environment for cocos2d and its pre-configured libraries, including cocos3d and Lua. Best of all, this book will have you making games right from the very start. It guides you step-by-step through the creation of sample games. These fun examples are modeled after popular App Store games and teach you key concepts of the new cocos2d 2 game engine and relevant tools like TexturePacker (texture atlas), PhysicsEditor (physics collision shapes), Particle Designer (particle effects), Glyph Designer (bitmap fonts), and others. This book offers a rock-solid introduction to creating games made entirely with cocos2d and little or no iOS SDK and OpenGL code. It also details alternative implementations, identifies the best free and commercial tools for cocos2d game development, features coverage of the author’s improved cocos2d game engine (Kobold2D), and even helps you enhance your game’s marketability on the App Store. What you’ll learn The process and best practices of mobile game development, including sprite batching, texture atlases, parallax scrolling, touch and accelerometer input. How to enhance your games using the Box2D and Chipmunk physics engines and other cocos2d-related tools and libraries. How to add UIKit views to cocos2d and how to add cocos2d to UIKit apps.
