Google Adsence page do not provide detailed statistics, e.g. when your ads are clicked, where is the clicker's IP, what ad does he/she clicked or which page the clicked ad is placed. We could simply use some client and server site script to record these data for your infomation. I'd like to...

When showing Google Adsence Ads in your LifeType Admin page, you may get the ‘Access Denied’ JavaScript error when choosing a resource or image. I’ve debugged into the JavaScript code today and find some potential conflicts between the editor and Adsence Ad. The editor is trying to visit...

In JavaScript, there's a 'wired' feature that the variable scope is only the function. For example, in the following code: var i = 1; { var i = 2; } alert(i); You will get 2 alerted. That's really interesting and everyone should pay more attention to.

Developing and debugging AJAX apps can be very tricky. The AJAX technology went on relatively soon while the development tools are slow and still catching up, so you do need to use a bag of neat tricks AND dirty/ugly hacks to see what is really going on. The first problem for beginners is where...

XmlHttpRequest supports both GET and POST requests to the server, which one should we use? As usual, GET is light and POST is heavy. But I'd say, it really depends on your scenario. GET requests pass parameters to the server using the query string. So we need to be careful about:...

The second parameter of the XmlHttpRequest.open method is the Url of the callback page: xmlRequest.open("GET", url, true); So far so good, things seem pretty-much straightforward. However, in a typical ASP.NET setting, an Url rewriter stands between the XmlHttpRequest and the actual...

Atlas is about Javascript OOP, AJAX, it offers client and server controls, cross-browser compatibility, UI enhancements, it supports flexible binding and a declarative programming style. Atlas integrates the ASP.NET server technology and allows to develop web applications. At the moment, Atlas...

Let's begin with the classic ‘Hello World!’ example. The HelloWorld.aspx page has one button. When the button is clicked, data is retrieved from the server and displayed in an alert box. One of the core features of Atlas is getting data form web server by asynchronous calls. In this...

I've just posted some topics about Atlas but seems no banner ads are shown in the post. I wonder if people do not like ASP.NET? Or something else? I've checked the keywords of page http://dflying.dflying.net/1/archive/72_extending_the_autocompleteextender_in_atlas.html at...

The Attributes of the @Page directive The @Page directive is the point of control for the developer with some new attributes that have been added to this directive: Async : If this is set to true, the page class that is generated derives from IHttpAsyncHandler. It adds some built in...

Atlas provides Web.Data.DataTable control which is just like the behavior of ADO.NET DataTable object and the Atlas Framework can also make the conversion between the two types for you automatically. Here are some common operations on Atlas DataTable. Get DataTable from server Server side...

UpdatePanel is so important an Atlas control that connects the traditional ASP.NET application and the new Web 2.0 AJAX implementation. That is, if you own applications wrote by ASP.NET, you do not need to take many changes to get it runs as the cool AJAX way by using UpdatePanel. Or, if you are...

Web Standard is more and more important in current web based application development. In these series of posts I am going to sharing some of my ideas about how to build Web Standard applications using ASP.NET 2.0. This post is the first in these series. It introduces some basic XHTML concepts...

The first Atlas control a developer may use should be the UpdatePanel, which is really powerful and easy to use. It provides us a closer view of Atlas. I’ve posted a simple introduction ( http://dflying.dflying.net/1/archive/96_introduction_to_atlas_updatepanel.html ) to UpdatePanel here and...

Binding in ASP.NET Altas is really a powerful way to connect two objects (You may find more info about binding here: http://dflying.dflying.net/1/archive/109_atlas_unleashed-bindings.html ). Atlas will automatically apply the changes of the property in source object to the target object if you...

Introduction It is much more challenging to write Atlas code than C# code, for there’s no compile time check or IntelliSence in coding, and you have to trace the traffic between the client and server in runtime. Still there’s no powerful IDE/debugger for JavaScript. I’ve been working on...

Components derived from the Action class in Atlas are used to specify the code to execute in response to events, which is similar to the event handlers. Action components enable you to declaratively bind actions to client events for common tasks such as calling methods, setting properties, and...

The Atlas framework provides amazing cross-browser support for drag & drop operations. Basically, to create a UI with drag & drop is really simple and we just need: Draggable items and Drop targets . Draggable items are DOM elements that can be moved around...

That will be very cool and useful if you can show your user a ProgressBar on a web page which displays the actual progress of some long operations. Now let’s try to make it possible by using ASP.NET Atlas. This post can also show you some basic conceptions about extending Atlas client side...
