admin A delegate is a type that references a method.Once a delegate is assigned a method, it behaves exactly like that method. The delegate method can be used like any other method,with parameters and a return value.
Any method that matches the delegate’s signature,which consists of the return type and parameters,can be assigned to the delegate.
Delegates allow methods to be passed as parameters.It can be used to define callback methods.

November 12th, 2008 admin A data source object (DSO) is a Microsoft ActiveX object embedded within a Web page. It employs a process called data binding, in which an ActiveXControl communicates directly with another Web page, or with an external XML source.
In order to take advantage of DSOs, it is necessary to have Internet Explorer version 4.0 or later. Web developers commonly create their own DSOs. For example, an animated weather radar image from the National Hurricane Center can be displayed continuously on the home page of a municipal civil defense department, without the need for clicking on a link to get to the National Hurricane Center site.
Data source objects are sometimes used for the purpose of implementing This type of intrusion shows up on spyware detection programs as a DSO exploit. Such spyware can be difficult to eradicate, and if it is successfully removed, it often returns.

November 10th, 2008 admin ASP.NET view state is the technique used by an ASP.NET Web page to persist
changes to the state of a Web Form across postbacks.That is when a form is submitted in ASP .NET, the form reappears in the browser window together with all form values.
The ViewState indicates the status of the page when submitted to the server. The status is defined through a hidden field placed on each page with a <form runat=”server”> control.
Hidden field placed on each page would be something as this
< input type=”hidden” name=”__VIEWSTATE” value=”CEbzzzEnmmz+Bc8IDFlnpgCLJ/HB00.” >
Maintaining the ViewState is the default setting for ASP.NET Web Forms. If you want to NOT maintain the ViewState, include the directive l%@ Page EnableViewState=”false” %> at the top of an .aspx page or add the attribute EnableViewState=”false” to any control.

The app is where your application specific folders and files will go. The separation between the cake folder with the core libraries and the app folder make it possible for you to have many app folders sharing a single set of Cake libraries. This also makes it easy to update CakePHP: you just download the latest version of Cake and overwrite you current core libraries; No need to worry about overwriting something you wrote for your app.
The tmp directory is used for various Cake operations, such as baking (automatically creating new php files), caching, and logging.
You can use the vendors directory to keep third-party libraries in. You’ll learn more about vendors later.
The folders structure and their basic purposes:
— root (the root directory)
— — app (here’s where your application logic will go)
— — — config (application specific configurations)
— — — controllers (controllers go here)
— — — — components
— — — index.php
— — — models (models go here)
— — — plugins (third party apps – go here)
— — — views (view related files go here)
— — — — elements (small repeated layout items go here)
— — — — errors (error pages go here)
— — — — helpers (your home-based helpers go here)
— — — — layouts (page layouts go here)
— — — — pages (static content managed by PagesController go here)
— — — webroot (this directory as your webroot, and stick your public files in here)
— — — — css
— — — — files
— — — — img
— — — — js
— — cake (this is where the libraries are placed: Note: it’s best not to touch)
— — index.php
— — tmp (used for logs, baking, etc.)
— — vendors (stick your third party libraries here)
