The Decorator Pattern & Extension Methods

  
The decorator pattern provides a formal way to add new functionality to an existing type, without sub-classing. First question: What is wrong with classical inheritance? In and of itself, nothing is wrong with the good old Is-A relationship. It is very common to derive a new class from an existing base class in order to override a few virtual members, and add a pinch of new functionality.

The Decorator Pattern & Extension Methods

  
Numerous design patterns exist in the software world today, and ultimately nothing is preventing you from making your own (if people buy into it or not is another question). Furthermore, there is no 'master list' of patterns that all developers agree upon. While this is true, if you pick up any book on the subject, you will find a set of very common patterns most programmers agree are very useful. Many of these patterns were first formalized in the seminal book on the subject, Design Patterns: Elements of Reusable Object-Oriented Software (aka, the Gang of Four [GOF] book; not to be confused with the UK punk band of the same name).

Xml File Methods and Properties

  
Method and Properties of XmlTextWriter class:
The XmlWriter class is a base class that outputs an XML data structure. It has methods to sequentially write XML elements in a proper hierarchy to create an XML file or other types of output streams. The System.Xml namespace provides support for the XmlWriter. It must be imported to the ASP.NET page with the directive

<%@ Import Namespace="System.Xml" %>

The XmlTextWriter

XmlWriter is an abstract class that is implemented as an extended XMLTextWriter class. The XmlTextWriter writes a sequence of XML nodes one element at a time. Output can be written to an XML file, although other streams of output data can be produced. It can create a new file or overwrite an existing file. Its non-cached writing techniques provides very fast generation of an output stream.

Session Timeouts

  

What are the issues (if any) of setting sessions to expire after an extended period of time as in 4-8 hours? I'm building an intranet app which is designed so that users will access it once in the morning and then leave it used, possibly, for hours at a time. I'm assuming that there aren't too many since

1) we're running it on a intranet
2) sessions are soley to retain state between requests
3) its not like a connection to the DB where you can conceivable run out


Page Methods and Yahoo UI

  

Hello people,
I'm constructing an application with Page Methods and YAHOO UI.
I'm Not using Update Panels because Page Methods are faster than Update Panel.

You can post your experiences with this feature of ASP.NET Extensions and vantages of using this type of architecture.

Thanks a lot.

Multiple web methods in one transaction

  

Hi everyone

Sorry I am kinda new in web services, so it may sound a bit newbish question.

We have a web service that comunicates with the database and exposes web methods that enables the application to access the database. Each method does only one operation (Insert, Update or Delete). What I need to do is create a transaction that will be consisted of multiple calls to the database, meaning multiple calls of more then one web methods. Can I do that? (I read that if the web method does not throw exception - or ContextUtil.SetAbort() is not called - the transaction will be commited automatically when the web method finishes executing, which I don't want to happen because I want to call another web method in the same transaction, and then manually commit the transaction)

Thank you in advance.


.NET Matters: Aggregating Exceptions

  

Exceptions in .NET are the fundamental mechanism by which errors and other exceptional conditions are communicated. This month's column provides information about how to aggregate exceptions to help manage a variety of scenarios in which multiple exceptions might result from one operation, including scenarios involving parallelism and concurrency.
