Update Single Column In Entity Framework

by Vahid 29. April 2011 18:00

I was working with Entity Framework and I needed to update a single column of a row in the database. basically I was logging the users visit to a web site (ASP.NET). so first time user lands in the website I create a record in database and keep the id in the session. when user’s session times out I needed to update the row and set the exit time of the user. it sounded a bit difficult to do this with Entity Framework I did it this way and worked pretty well:

Windows Server AppFabric

by Vahid 13. February 2011 05:15

if you have been involved in the enterprise application architecture and development, for sure you have also faced the memory constraint when designing the application. the thing is that as soon as you talk about enterprise application –I mean real enterprise application- you are talking about a huge amount of data being processed and traveling between systems. that’s when you say oops, I need to take care of this, user and my hardware cannot afford these expensive operations each and every time a request comes in. then you start thinking about caching the information somewhere. ok, some out of the box caching –i.e. ASP.net Caching- is there but we are talking about huge amount of data and keeping them on the same server as the application server would be out. and that’s the time you say Valla to keeping the data in a database. you go ahead and do it but as soon as you run the first load test with few thousand concurrent users the “sh..t” word comes out. you see the bottlenecks connecting to database, you see the performance degrade and you see that you have made your business owner to spend some good amount of money for the database licenses but you are not getting the result you were after. exactly at this point of time you would wish that there was a technology to help you out with the situation and if you have heard of Windows Server AppFabric and know it, than you feel how much you are blessed.

Assign a static port to Asp.net Website

by Vahid 15. December 2009 08:04

A while ago in a project we had the requirement to assign a static port number to our asp.net website project. The very first thing came to my mind was that we just can assign static port number to asp.net web application project type and we cannot assign a static port to asp.net web site project. Anyway I started searching in the internet for a solution to make sure about it. I spent quit a long time looking for an answer but I could not find any almost everywhere it was mentioned that we cannot assign a static port to a asp.net website and it is constrained to use dynamic port.I was convinced at the time and we managed to convert to asp.net web application. Surprisingly recently a friend of mine, Ali, referred a perfect solution for this issue to me and I thought it’s worth sharing with you. Step 1- the very first step is to add the asp.net Web Server external tool to Visual Studio. To do so

Static port number assignment functionality comes handy in many situation starting from an automated testing.The following table lists Web project options or tasks and indicates which project model best implements those options.

Do You Know About T4 (Text Template Transformation Toolkit) Code Generation In Visual Studio?

by Vahid 14. April 2009 03:15

Working with Microsoft products always has some surprises, now be it a defect, missing functionality or an unknown cool new feature. What’s the story? Well recently i was listening to a DotNetRocks show in which i heard the word “T4” which is something regarding to code generation in Visual Studio 2008! i was like, what is this? How come that i have not heard it before? Anyway I was really surprised. So as a code generation passionate i did some R&D about it and here is the outcome. What is T4? T4**is a code generator built right into Visual Studio. To be clear, we HAVE THIS NOW on our system.**So now is the right time to introduce code generation to our company. this means If we are doing something twice or more, manually, in our project, we should stop it and generate it instead. However, there is an issue with this technology and that’s the fact that Microsoft does not support it completely as of now and this reason why it is kind of hidden in VS. There’s no item templates in File | New Item and there’s no intellisense or syntax highlighting. However you don’t need this, but if you want really get the most out of T4, first, have a look at “T4 Editor Community Edition.” That’ll get you some basic coloring.

ASP.NET Web User Controls VS. Web Custom Controls

by Vahid 3. March 2009 03:54

Web user controls are easy to make, but they can be less convenient to use in advanced scenarios. You develop Web user controls almost exactly the same way that you develop Web Forms pages. Like Web Forms, user controls can be created in the visual designer, they can be written with code separated from the HTML, and they can handle execution events. However, because Web user controls are compiled dynamically at run time they cannot be added to the Toolbox, and they are represented by a simple placeholder glyph when added to a page. This makes Web user controls harder to use if you are accustomed to full Visual Studio .NET design-time support, including the Properties window and Design view previews. Also, the only way to share the user control between applications is to put a separate copy in each application, which takes more maintenance if you make changes to the control.

Limitation in dbms_output.put_line in pl/sql

by Vahid 18. February 2009 10:32

Today I was testing a function in pl/sql using pl/sql developer. In the function we are contenting so many strings that the leng of the final string would go more than 4000. As usual I was trying to use dbms_output.put_line to debug the function and make sure the end result is ok. But at the end of the function when I was trying to print the final string using this function I was not getting the expected result. the string was being truncated. First I thought there is a problem with varchar2(4000) data type which I had declared for my variable. So I changed the data type to LONG which can hold unto 2GB of data. But still the same issue was there.Spending sometimes on the issue I thought there may be some limitation to the put_line function. So I created a temporary table with a single clob column and inserted the final string into that column instead of printing to out window. Surprisingly it worked properly and I was able to see the whole string from the column. Doing some R&D on this I came to know that dbms_output.put_line() function has just a buffer of 2000 characters and it will only print 2000 chars. I was not able to find out any way to increase this buffer size but once I find it, I’ll write about it.

LINQPad is also a great way to learn LINQ: it comes preloaded with 200 examples from the book, C# 3.0 in a Nutshell. And finally LINQPad is more than just a LINQ tool: it’s a code snippet IDE that instantly executes any C#/VB.net expression, statement block or program. Put an end to those hundreds of Visual Studio Console projects cluttering your source folder! you can get it from here.

one issue we usually face while developing an ECommerce application is testing credit card payment system. so here is list of credit card numbers we can use to test payment system.

American Express: 3111-1111-1111-1117

Visa: 4111-1111-1111-1111 or 4222-2222-2222-2222

MasterCard: 5111-1111-1111-1118

Discover: 6111-1111-1111-1116

remember that CCV number and Name does not matter but you should keep the amount bellow $500 dollars and also make sure expiration date is not today but in the future.

Comparision between C# and JAVA

by Vahid 25. January 2009 15:30

here is a quick comparision between microsoft c# (.net) and java

Concept	C#	Java	Notes
Virtual machine	CLR	JVM	CLR is not quite the same as JVM concept, but very similar.
Namespace	namespace/ using	package/ imports	C# allows multiple namespaces in a file, Java does not.

Attributes	[attribute]	@annotation	C# 1.0, Java 1.5
Base class	base	super
abstract objects	abstract class	abstract class
abstract methods	abstract	abstract
sealed objects	sealed	final	In both cases, sealing is discouraged.
sealed methods	sealed	final
replacement methods	new keyword	not supported	Effectively ignores the base method.
constants	const / readonly	final static
Enum’s	enum keyword	enum keyword	C# 1.0, Java 1.5
virtual functions	explicit virtual	always virtual	This is one of the gotcha’s when working between the two languages
override intention	override	@Override (though members override by default)	Causes compiler error if method is not actually overriding a base method.
Class/Type representation of simple types	Map 1:1 with the simple type keywords.	Behave different to simple type keywords.	C# seems more natural than Java in it’s behavior
Getters/Setters	get/set keywords, behave like properties	Explicit get/set methods	Again, C# seems more natural with this.
Events	Typically via delegates	Typically via interfaces
Reference equivalence	Object. ReferenceEquals()	==	Another C# vs Java gotcha.
Value equivalence	== or Object.Equals()	object.equals(), == for value types	Java’s choice of using == for reference equals adds to the need to distinguish between objects and value types.
Object introspection	Object.GetType()	object.class	Very similar
Exceptions thrown by method	implicit	throws keyword	Actually liking Java’s philosophy here, albeit taking some getting used to.
Stack scoping	using keyword, or try/finally keywords	try/finally keywords	‘using’ keyword is syntax sugar that calls IDisposable.Dispose() method at end of block.
Simple synchronization	lock keyword	synchronized keyword	‘synchronized’ can also be used on a method.
Generics	class<type>	class<type>	C# 2.0. Java 1.5. C# has a cleaner implementation and discovery of generics in reflection. In Java, class and class<type> cannot co-exist. class becomes synonymous to class.
Output parameters	out, ref	Not allowed	Not a huge loss in Java, there are simple workarounds.
Switch fall-through	Not allowed	Allowed
iteration	foreach(type x in y)	for (type x : y)	C# 1.0. Java 1.5.
Lambda/Closures	=>	(future)	C# 3.0. Java 1.7 (maybe)

export to excel but in new page

by Vahid 20. January 2009 05:42

in the last sub system which we were working on, there was requirement to export the result of a query which is from oracle database and is displayed in an asp.net data grid into excel file. but the component we are using for export to excel functionality gets the collection as input parameter and export the data to excel file and write the excel file into response object of the asp.net. this means once the functionality is invoked, a dialog box will be displayed asking Open the file, save the file of cancel the operation. no issue with save and cancel. but when they clicked on the open it opens the excel file in the same browser window where they were viewing the page and they close the window once they were through with viewing the excel file. this means they close the application.

by Vahid 13. January 2009 13:42

i am sure these you hear about REST, so want to know what rest is? then have a look at the following definition

Representational state transfer (REST) is a style of software architecture for distributed hypermedia systems such as the World Wide Web. As such, it is not strictly a method for building “web services.” The terms “representational state transfer” and “REST” were introduced in 2000 in the doctoral dissertation of Roy Fielding,one of the principal authors of the Hypertext Transfer Protocol (HTTP) specification.

Sort based on input parameter in oracle query.

by Vahid 10. January 2009 09:15

Today I was tracing a defect happened in a stored procedure with paging functionality. After spending sometimes on it I came to know that sorting does not work properly. In the order by clause of the procedure we were using an input parameter which holds the column name based on which the result was to be sorted. But it seems that oracle and pl-sql does not support this feature and if we want to sort based on an input parameter we have to go for dynamic query which I don’t like at all.But it’s funny that the feature is not there in oracle because the same thing can be done in ms sql server easily.Anyone got some idea about this, please let me know.

hi,

as you may know c# is missing the nice and usfull IsNumeric function which is available in VB.net. but it is a trivial task to implement a generic equvelant function for it. look at the following code. it will return true if the value is numeric and false if the value is false.

HR Manager story

by Vahid

January 2009 18:59

One day while walking down the street a highly successfulHuman Resources Manager was tragically hit by a bus and she died. Her soul arrived up in heaven where she was met at the Pearly Gates by St. Peter himself. “Welcome to Heaven,” said St. Peter. “Before you get settled in though, it seems we have a problem. You see, strangely enough, we’ve never once had a Human Resources Manager make it this far and we’re not really sure what to do with you.” “No problem, just let me in,” said the woman. “Well, I’d like to, but I have higher orders. What we’re going to do is let you have a day in Hell and a day in Heaven and then you can choose whichever one you want to spend an eternity in.” “Actually, I think I’ve made up my mind, I prefer to stay in Heaven”, said the woman “Sorry, we have rules…” And with that St. Peter put the executive in an elevator and it went down-down-down to hell. The doors opened and she found herself stepping out onto the putting green of a beautiful golf course. In the distance was a country club and standing in front of her were all her friends - fellow executives that she had worked with and they were well dressed in evening gowns and cheering for her. Th! ey ran up and kissed her on both cheeks and they talked about old times. They played an excellent round of golf and at night went to the country club where she enjoyed an excellent steak and lobster dinner. She met the Devil who was actually a really nice guy (kindof cute) and she had a great time telling jokes and dancing. She was having such a good time that before she knew it, it was time to leave. Everybody shook her hand and waved goodbye as she got on the elevator. The elevator went up-up-up and opened back up at the Pearly Gates and found St. Peter waiting for her. “Now it’s time to spend a day in heaven,” he said. So she spent the next 24 hours lounging around on clouds and playing the harp and singing. She had great time and before she knew it her 24 hours were up and St. Peter came and got her. “So, you’ve spent a day in hell and you’ve spent a day in heaven. Now you must choose your eternity,” The woman paused for a second and then replied, “Well, I never thought I’d say this, I mean, Heaven has been really great and all, but I think I had a better time in Hell.” So St. Peter escorted her to the elevator and again she went down-down-down back to Hell. When the doors of the elevator opened she found herself standing in a desolate wasteland covered in garbage and filth. She saw her friends were dressed in rags and were picking up the garbage and putting it in sacks. The Devil came up to her and put his arm around her. “I don’t understand,” stammered the woman, “yesterday I was here and there was a golf course and a country club and we ate lobster and we danced and had a great time. Now all there is a wasteland of garbage and all my friends look miserable.” The Devil looked at her smiled and told…
