What's going on?

UnquaLe — Fri, 09 Jan 2009 21:34:00 +0200

I didn't blog for a long time because i was busy on some projects to improve myself on ASP.NET MVC, Unit Testing and Castle Framework. Me and my friend Tuna Toksoz and Berker Peksag are working on an open source Blog project called as BlogSharp. Our first goal is to improve ourselves so while doing this i am planing to blog about the things i have discovered.

ALT.NET global comunity is growing and we decided to create a local Turkish ALT.NET group to introduce ALT.NET concepts and to learn more.

How to use the IHttpAsyncHandler in ASP.NET

UnquaLe — Mon, 30 Jun 2008 11:34:00 +0200

Before reading this post you have to know what IHttpHandler intaface does.

Basically, the IHttpAsyncHandler interface allows you to serve content asynchronously from a HTTP handler. This is great when you need to free up the worker thread to do processing like IO work etc. ASP.NET actually uses fewer threads when it runs asynchronously, which is great for performance and scalability. That’s because each thread is returned much faster to the thread pool.

There you are a simple example.

10 Tips to Improve your LINQ to SQL Application Performance

I have found very helpful article that you would like also about performance of Linq to SQL. These optimizations will bring us to ADO.NET SqlDataReader performance.

There you are the article.

Linq to Regex - Regex goes easier

UnquaLe — Thu, 08 May 2008 00:45:00 +0200

I won't talk about how regex is useful. You know regex patterns are ugly and hard to understand then I saw Josh Flanagan's Readable Fluent Regex Api, there is another thing to like LINQ rigth now.

Very nice example to see how the api is cool.

ScriptCombining Feature

UnquaLe — Fri, 07 Mar 2008 12:01:00 +0200

I was reading the post (Mix08 Session Overview: Building Great AJAX Applications from Scratch Using ASP.NET 3.5 and Visual Studio 2008) from Brad Abrams then I have seen very cool feature to combine the scripts into a single request that saves the round trip and compresses better.

The text is from his post;

Download the completed sample or just the starter files to play along at home.

We can use the new ScriptCombining feature to combing the scripts into a single request that saves the round trip time and compresses better.

But first we need to know exactly what scripts are being loaded. To see this let's look at the ScriptReference debugging tool.

Just drop it on your page

	    <cc2:ScriptReferenceProfiler ID="ScriptReferenceProfiler1" runat="server" />

and you see exactly what is loaded.

We also, have both the debug and retail scripts ready to download in case we want to share this across several pages.

Then cut and past that into ScriptManager.

			<asp:ScriptManager runat="server" ID="sm">
	<CompositeScript>
	<Scripts>
	<asp:ScriptReference Name="MicrosoftAjax.js" />
	<asp:ScriptReference Name="MicrosoftAjaxWebForms.js" />
	<asp:ScriptReference Name="AjaxControlToolkit.Common.Common.js" 
	Assembly="AjaxControlToolkit, Version=3.0.11119.25533, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e" />
	<asp:ScriptReference Name="AjaxControlToolkit.ExtenderBase.BaseScripts.js"

	Assembly="AjaxControlToolkit, Version=3.0.11119.25533, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e" />

	</Scripts>
	</CompositeScript>
	</asp:ScriptManager>

Now, let's go back to firebug...

This time, we have two request 118KB and 4.39s... Much better!

Patterns & Practices Practices Checker - ASP.NET Web Applications Performance Code Review

UnquaLe — Tue, 29 Jan 2008 13:14:00 +0200

I thought it gonna be fine to cross-post it from Patterns & Practices Guidance:

Patterns & Practices Practices Checker - ASP.NET Web Applications Performance Code Review

The Patterns & Practices Practices Checker is a tool that helps you verify your applications against the patterns & practices performance recommendations for ASP.NET applications.

Use Practices Checker to help you perform a manual code inspection by analyzing your application for potential coding and configuration settings that do not adhere to the patterns & practices ASP.NET Performance Checklist.
Extend Practices Checker by allowing additional checklists to be created and checked.
Developers can utilize built in search routines to search intermediate language, static text files and .configuration files for specific code patterns or settings.

Windows Live Messenger IM Control

UnquaLe — Thu, 10 Jan 2008 11:51:00 +0200

The Windows Live Messenger IM Control enables web sites to show the presence of Windows Live Messenger users and lets site visitors engage in instant messaging conversations with the Messenger users. A Web site can invite its users to share their Messenger presence and exchange messages with visitors to the site. When a site hosts the Windows Live Messenger IM Control, site visitors can instant message Messenger users directly from the browser without installing the Windows Live Messenger desktop client on their computers.

This pretty good control is easy to use. You will only add the IFrame code that Live messenger gives you then you can start having conversations with your visitors of your personal web page and blogs easly.

MSSQL SERVER 2008 New Features for Developers

UnquaLe — Mon, 26 Nov 2007 15:58:00 +0200

Mssql Server 2008 is close to release. It is currently releasing as CTP and still growing with new features. I went to a seminer @ Microsoft from .NET community and i ve seen some cool stuffs so I want to preview some of them with you.

MSSQL SERVER 2008 New Features for Developers

Data Types

MSSQL Server 2k8 contains some new datatypes. These are DATE, TIME and some CLR based types.

DATE type stores only date without time. And TIME type stores only time withouth date. J It was alittle hard work to use date functions for time actions. I think these types can help us.

There is an another type for date. DATETIME2, is similir to standart DATETIME but allows for greater precision. The range of the type is Jan 1 year 1 to 12/31/9999. So it wont be a problem to store DateTime.MinValue with this type. Also the clock is 24 hour cycle so 8 pm can be stored as the military time 20:00.

SELECT CAST('2007-10-20 20:30:05.1234567' as DATETIME2)

Results:  2007-10-20 20:30:05.1234567

SELECT CAST('2007-10-20 20:30:05.1234567' as DATETIME2(4))

Results:  2007-10-20 20:30:05.1235

Values that need to be time zone aware can now be stored in Mssql Server 2k8 with the DATETIMEOFFSET.

SELECT CAST('2007-10-20 20:30:05.1234567 +5:0' as DATETIMEOFFSET)

Results:  2007-10-20 20:30:05.1234567 +05:00

Demos :

CAST('2007-10-20 20:30:05.1234567 +5:0' as DATE) = 2007-10-20

CAST('2007-10-20 20:30:05.1234567 +5:0' as TIME(7)) = 20:30:05.1234567

CAST('2007-10-20 20:30:05.123' as SMALLDATETIME) = 2007-10-20 20:30:00

CAST('2007-10-20 20:30:05.123' as DATETIME) = 2007-10-20 20:30:05.123

CAST('2007-10-20 20:30:05.1234567 +5:0' as DATETIME2(7)) = 2007-10-20 20:30:05.1234567

CAST('2007-10-20 20:30:05.1234567 +5:0' as DATETIMEOFFSET(7)) = 2007-10-20 20:30:05.1234567 +05:00

FILESTREAM Data type

We always think where to store our BLOB files, in the FileSystem or in to the DB. It is hard desicion between them. You can store your files in to the db with filesystem support. For more details i think you should read this post : http://blogs.msdn.com/manisblog/archive/2007/10/21/filestream-data-type-sql-server-2008.aspx

HIERARCHYID

When do we need to have parent – child relationship we create a foreignKey to the table itself. So HierarchyID type will make it easy and it has some helpful funtions.
Details on here :
http://blogs.msdn.com/manisblog/archive/2007/08/17/sql-server-2008-hierarchyid.aspx

http://blogs.msdn.com/manisblog/archive/2007/08/28/sql-server-2008-hierarchyid-part-ii.aspx

GEOGRAPHY

Spatial data types means businesses and products can now handle complex location data and apply it against other business or technical specific data without requiring expense GIS systems.

Now we are able to insert many records to be inserted using VALUES clause of the INSERT statement.

INSERT INTO SalesFeed
(CustomerID, Product, SaleAmount)
VALUES
(1,'PoolTable', 1000),
(2,'BigScreen', 955),
(3,'Computer', 590),
(4,'BigScreen', 880),
(5,'Computer', 700)

There is a new Linq2Sql provider for sql server 2008.

There are some comprassion features, some more new T-SQL enchantments. I wantted to list these features that i like and I want to notice that Microsoft will stop supporting ms sql server 2000 in April 08’.

I hope it helps..
