Top 3 paradigm shifts that will shape the future of developers

2010-07-01T19:21:00Z

Computing is one of the areas that change is the fastest. New hardware and software are continuously released from labs, get into the market and enter to the cycle of being cheaper. Developers, who creates the software for the products are the first ones hit by change and should adapt, if they don’t want get behind. Therefore, being aware of the trends, especially the ones that will shift the paradigm help us, developer community, to act earlier. And I see 3 changes that we’ll shift the paradigm in the near future: [read more.....]

IDEAS

2010-06-27T20:08:00Z

Hi, folks. Yesterday, I opened my new blog on Java, Android and other stuff, IDEAS, (http://enestaylan.com/ideas/). Here, in this blog I'll continue to write on .NET. You can read my first post of IDEAS "Why I needed a new Blog?" from here.

Reading RSS data with Linq to Xml

2010-04-20T12:15:00Z

Linq to Xml is the best method, I think, for querying, constructing and writing Xml data. In this article, I'll show how to read Rss data with this powerful Xml technique, Linq. Now, create a Website in Visual Studio, add a Textbox and a [read more....]

Delegates and Events in C#

2010-03-15T20:55:00Z

Events and their underlying mechanism "Delegates" are very powerful tools of a developer and Event Driven Programming is one of the main Programming Paradigms. Its wiki definition is "event-driven programming or event-based programming is a programming paradigm in which the flow of the program is determined by eventsi.e., sensor outputs or user actions (mouse clicks, key presses) or messages from other programs or threads." That means, your program can go its own way sequentially and in the case of anything that requires attention is done (when an event fires) by somebody or something, you can response it by using that event's controller method (this mechanism is like interrupt driven programming in embedded systems). There are many real world scenarios for events, for example, ASP.NET uses events to catch a click on a button or in your app, controller has notice of a change in UI by handling events exposed by view (in MVC pattern).

RIA, Silverlight, Microsoft, Oracle, The Future of The Web and Web Technologies

2010-02-23T19:27:00Z

Internet and computers are where things change fastest. Look at web technologies (and companies. Google is 12 and Facebook is 6 years old. Their revenues are $23 billion and $300 million, respectively). About in last 15 years user experience on the browser has changed dramatically: from static HTML pages, to dynamic web sites with advanced JavaScript capabilities (look at your Facebook Profile) and to the ultimate Rich Internet Applications (RIA) along with web technologies to offer best technologies and experience. Companies and communities have developed many technologies, programming languages and frameworks on browser and server side: JavaScript, ASP, PHP, Python, Ruby, JSP, JSF, ASP.NET etc. On PHP side, new versions have come to the use of developers and it dominated small websites (like small news websites) and is used by some big companies like Yahoo because of these companies' desire not to be dependent on another companies so they selected open source. JSP on Java side, has been used by many enterprises in their large scale websites. JSF was released as the successor of JSP but couldn't gain market share. On Microsoft side, ASP and its successor ASP.NET was released for dynamic websites and have been used by enterprises generally. All technologies [read more....]

Taking Snapshots in ASP.NET

2010-02-06T19:15:00Z

Taking snapshots of web pages is used by many applications, for example Wordpress shows a small snapshot image of the page that a link directs to. In this post, I'll show how can we get snapshot image of a web page by using a small program, an .exe executable. Hence, it is the executable that creates the image actually and our asp.net page will make use of that .exe. First create a website, add a textbox and a button like below: [read more....]

Dragging with Silverlight Thumb Control

2010-01-06T17:45:00Z

Dragging can be a useful feature in various scenarios especially in visually compelling ones. In Silverlight we can add drag capabilities to almost every element by using their MouseMove event. However, this method doesn't provide us a smooth drag experience. For example, when we drag a rectangle control by using its MouseMove event, dragging it to LHS immediately after RHS direction just stops the control. Therefore, we'll use Thumb control that is designed to be dragged with its specialized events. Let's begin: [Read More]

Iterating through Page Control Collection using Linq

2009-11-07T11:17:00Z

Linq is used generally to get and manipulate data by using Linq to Sql, Linq to Entities or Linq to Xml. However, it can work on many collections in .NET Framework. Now in this post, I'll show how to work on Page Control Collection with Linq. Think about the scenario you want to get every textboxes that has a text in it. To see which ones we select add them a text you want.

Create a new .aspx page and add several textboxes to it. They can be directly in page or another control (i.e. a panel control). Then add the code below to [Further]

.NET IO - 1 ( Creating and Deleting Files and Directories and Listing subfiles and subdirectories )

2009-09-25T18:09:00Z

There are advanced classes in .NET for IO processing. Even though we have some classes that allow us to carry out low level IO operations, we can usually do our work with several static methods. Now let's see how a directory and a file is created, deleted and how directory hierarchy in a disk volume or in a directory can be displayed in tree view. Although IO operations are same in all .NET projects, to make easier our article I use ASP.NET. Hence you can easily copy and paste code below in, for example, WPF. Classes, we will use, are:

WHICH FEATURES A GOOD WEBSITE SHOULD HAVE?

2009-09-24T17:02:00Z

Websites that are data-driven, content-based, real-world, have some shared features. This features are much more important than the past, because we have in the era of social media and competence is heavier. These features are: [Further]

HOW TO USE CACHE AND CACHE DEPENDENCY ?

2009-09-24T16:58:00Z

Using cache is an easy way to increase efficiency in programs. By using cache techniques we can store the data in RAM that is normally in harddisk or another stuff whose access time is much bigger than RAM's. In this article, I will write a method that gets the subdirectory names in a directory and return them to caller. ( this method can be used, for example, to populate theme names in a dropdownlist so that user can select her preferred style. "When [Further]

JQuery SELECTORS

2009-09-24T16:54:00Z

Today, I worked some on Jquery. Firstly, my interest was just to find some plugins to create nice pop-ups to show images. But, later I found myself in the docs of JavaScript and Jquery. As a programmer who works with major languages like Java, C#, ASP.NET, I understood how much I’ve ignored this important concept of web programming especially after seeing power of Jquery. To create shared functionality between several elements ( that shares some type of sign ), using Jquery is a very good solution in some problems (for example, highlighting codes in a document , like in this website, use name attribute in <pre> tags and give them some cool css features. This would require very strange and humble solutions when using just C#.) Now, in this entry, I am beginning a new series of articles: Jquery articles. First one: Getting Started with Jquery.[Further]

CACHING WITH SQL DEPENDENCY SUPPORT-1

2009-09-24T16:48:00Z

Caching data that comes from an SQL database (in other words dependencies to database tables) in RAM has been supported since ASP.NET 2.0. In practice this means, we can cache the data for undetermined period until the source database table is updated. This cache mechanism works for SQL Server 7 and later including SQL 2005 and SQL 2008. SQL 2005 and SQL 2008 supports another type of cache invalidation based on events. I call first mechanism as Table Level SQL Dependencies and second as Command Level SQL Dependencies. In this article, "Table Level SQL Dependencies" will be spoken. For "Command Level SQL Dependencies" you can look at "Caching with SQL Dependency Support-2". [Further...]
