‘Back to basics’ - Presentation

2010-05-09T11:35:00.001+05:30

Recently in my current organization, we planned to retake training session for refreshing.

As part of this “Back to basics” series, I have started with ‘.NET framework basics’. Slide show which I presented in session is shared here.

(CLR via C# – book lovers can say as which is the main source I used, soon after seeing the slides).

Planed for some more presentations, let see how they will go.

Create certificate for - Windows Azure Service Management API - Authentication

2009-10-27T22:57:00.001+05:30

Technorati Tags: Windows Azure,Azure,Storage,Cerebrata,Utilities,X509,certificate

I was tried to access my Azure Hosted service”, using Windows Azure Service Management API. This just released (september 2009) API, currently doing authentication using

From MSDN,

Any valid X.509 v3 certificate can be used for authentication. You can use a self-signed certificate or one signed by a certificate authority.

To access our “Azure Hosted service” using “Azure Service Management API”, we need to upload our Certificate certificate file (*.cer) to the Azure Portal. [this kind of authentication may be changed by Microsoft, since this API is now in earlier version]

Some Useful links about “creating Certificate file”:

Using MakeCert.exe : from msdn link

Using IIS to generate a X509 certificate : from Eric Nelson’s msdn blog link

Azure Hosted Service Manger Tool

Currently Cerebrata company, is in process of creating WPF based tool which uses this API. Once screenshot of this tool for view.

I will update about this application in later post.

Azure Contest – Jaiho application

2009-08-04T02:18:00.001+05:30

Around one and half month back, I came to know about in NewCloudApp() developer challenge. It was a contest for creating Windows Azure based web application (or) service. I participated in that same [In 'international category'] with hearty support from my friend Ashok. Created a application called "Jaiho" and hosted here.

Now the contest is completed, congrats to the winners. My application is not selected, however thanks to all who tried the Jaiho application and voted for this.

About application "Jaiho" application:

Initially we planned to implement many functionalities for this website as like “big social networking website” like Facebook, Orkut.

Due to time limit, and laziness only few functions were implemented while hosted for contest.

Currently following functionalities are in this application,

User can create an account newly (by new username, password) (OR)

User can also create account by other web 2.0 website’s username password (OpenID / OAuth based User Authentication)

Anyone can do “Search operation” by “myBing” section [it is using Bing search engine’s API]

After creating account, user can store any files into this website (internally storing the data in Azure Blob storage)

Currently all uploaded files accessible to public (will be changed, based on user choice)

I missed to post the details about “Jaiho” in this blog. Here below the excerpt of the mail which I sent to friends to promote this app for voting. Please Note: this below image is also hosted in cloud (by my account in Jaiho application). (i.e) image URL is:

Update (05-Nov-2009):

Recently got notice from Microsoft, as I have to shift all my application/storage data to anther “region”, and previous data will get deleted. Excerpt of that notice is as follows:

“You are receiving this mail because you have an application or storage account in Windows Azure in the “USA - Northwest” region. Windows Azure production applications and storage will no longer be supported in the ‘USA-Northwest’ region. We will be deleting all Windows Azure applications and storage accounts in the “USA - Northwest” region on November 3rd.”

So, currently this basic application is down

Few bits about Cloud Computing & Microsoft Azure Platform

2009-07-14T01:03:00.001+05:30

Cloud Computing & few bits about Microsoft Azure Platform,

Cloud Computing

[From wikipedia, (http://en.wikipedia.org/wiki/Cloud_computing )]

Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet.

Leading companies offering Cloud Computing services, including:

Amazon
Google
Microsoft

Amazon

Amazon EC2 (Amazon Elastic Compute Cloud) - web hosting service http://aws.amazon.com/ec2/
Amazon S3 (Amazon Simple Storage Service) - providing storage in internet http://aws.amazon.com/s3/
and many services like it... ...

Google

Google App Engine - http://code.google.com/appengine/docs/whatisgoogleappengine.html

Allows to host application written in Python & Java

Microsoft

Azure services platform. Windows Azure - http://www.microsoft.com/azure/windowsazure.mspx

Allows to host application written in ASP.NET & PHP

Java applications can also utilize “.NET services” by separate SDK

We can create, test and debug the applications using Visual Studio

Windows Azure Service Platform

Windows Azure is the cloud services operating system that provides various functionality for Cloud Computing. It serves as the development, service hosting, and service management environment for the Azure Services Platform. Windows Azure provides on-demand compute & storage services on the Internet in Microsoft data centers.

It provides various services including,

.NET Services
Azure Storage Services
Live Services
SQL Data Services.

Azure Storage Services

Windows Azure Tables
Windows Azure Blob
Windows Azure Queue

Windows Azure "Tables"
- Used for "DBMS like" functionality. provides scalable, durable structured storage in the form of tables. The tables contain entities, and the entities contain properties. support ACID transactions. It can be accessed as "REST programming approach" via "ADO.NET Data Services".

Windows Azure "Blob"
- Used for "storing Binary data" (ex, Photos, Videos any any type of files).

Windows Azure "Queue"
- provides reliable storage and delivery of messages for an application.

Microsoft .NET Services

- set of developer-oriented services that provide key building blocks "for communication among applications".

[Much like the .NET Framework, for the Cloud computing].

Access Control Service
Service Bus

Access Control Service
- The Access Control Service is a cloud-based "Security Token Service (STS)". It provides way for standards-based identity checking.

Service Bus
- provides the familiar Enterprise Service Bus application pattern.

Live Services

- is a set of building blocks for handling "user data and application resources". Live Services includes Mesh technologies for synchronizing user data and extending Web applications across multiple devices.

Article Published – ADO.NET Data Services

2009-06-16T23:23:00.001+05:30

Few months before, I was checking about ADO.NET data services. Same I pointed out in my old post. I had put some initial notes in document for further view, and just forwarded that as a article to publish in ‘Chirp’ [in-house magazine in current employer] before 3 months.

This month publication, having that article.

I shared that here (in SkyDrive) for download, or you may view & download from below ‘docstoc’ upload.

Unicode and Character Sets - Basis

2009-05-08T23:25:00.001+05:30

I have read an great technical article by Joel Spolsky. Actually it was written on year 2003 [October 08, 2003]. But read today.

ok, coming to point. That article is about basis of “Unicode Char sets”

title and URL,

The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)

http://www.joelonsoftware.com/articles/Unicode.html

just tiny bit from that article,

Some people are under the misconception that Unicode is simply a 16-bit code where each character takes 16 bits and therefore there are 65,536 possible characters. This is not, actually, correct.

Lengthy article but worth reading. Make you free to read this.

MCTS 70-503 Exam (WCF)

2009-03-23T02:29:00.001+05:30

Update: I added links to useful blogs and articles in new post, click here

Last Saturday 21-Mar-2009, I attended WCF 3.5 Certification (MCTS 70-503) exam, and cleared.

I did my initial two MCTS exams in 2007. After that, I was sayinng a long time about getting further certifications, but went only in words for long time.

Started preparation on 70-529 (.NET 2.0 - Distributed Application Development) after long time. As you know that was too delayed work. Because Microsoft has already released WCF, a new unified connected systems technology.

So continued with WCF.

Thanks to all who supported, and special thanks to Ashok.

I will update about some important links to WCF, in later post.

Dangerous Programming Mistakes

2009-02-21T13:43:00.001+05:30

>> Just recently I did the #1 mistake

>> Please have a time to view this list

Top 25 Most Dangerous Programming Mistakes

1. Improper Input Validation

Ensure that your input is valid. If you're expecting a number, it shouldn't contain letters. Nor should the price of a new car be allowed to be a dollar. Incorrect input validation can lead to vulnerabilities when attackers can modify their inputs in unexpected ways. Many of today's most common vulnerabilities can be eliminated, or at least reduced, with strict input validation.

2. Improper Encoding or Escaping of Output

Insufficient output encoding is at the root of most injection-based attacks. An attacker can modify the commands that you intend to send to other components, possibly leading to a complete compromise of your application - not to mention exposing the other components to exploits that the attacker would not be able to launch directly. When your program generates outputs to other components in the form of structured messages such as queries or requests, be sure to separate control information and metadata from the actual data.

Fiddler : HTTP Traffic Debugger Proxy

2009-02-14T01:02:00.001+05:30

While studying the basis of “ADO.NET Data Services”, I came to know about an excellent tool called “Fiddler”.

HTTP Web Debugger Proxy
Logs all the HTTP Traffic
so able to view all HTTP communication, in may formats (as RAW format, as XML.. and may more options).

really useful, if you haven’t used yet, consider this. Here it is :http://www.fiddlertool.com/

Info about “Fiddler” in MSDN:
http://msdn.microsoft.com/en-us/library/bb250446.aspx

Earlier while starting with .NET 2.0 XML web services, I was struggled to trace SOAP messages communication. I don’t heard about this that time. Fortunately now no problem about that. :-)

Looking at : ADO.NET Data Services

2009-01-27T20:41:00.000+05:30

These days am looking in a new component in .NET Framework.
It is a new approach of "accessing the data".
It is "ADO.NET Data Services"

It is interesting, because we are going to access the data "as service".
Started to work with this.

Just here am sharing some introduction details what I got.

- Data as a Service
- Earlier code named as ‘Astoria’
- Part of .NET Framework 3.5 SP1
- REST based approach
- So, Best Suitable for Rich Interface Applications (like ASP.NET AJAX, Silverlight)
- Accessible by all kinds of .NET Application

Main thing is, as in the client's view, we are going to access the data using URIs

Some URI examples:
http:// myserver / data.svc / Customers
By this we can get all customer details

http:// myserver / data.svc / Customers(‘userA’)
By this we can get only particular "userA" details

So, how it is working only with URI itself for Accessing the data.!!!?
Because, it is working with HTTP methods GET, POST, PUT and DELETE

As a learning workarounds, "ADO.NET Data Services" would be around the following

· ADO.NET Entity Framework

· ADO.NET Entity Data Model

· LINQ

· Web Services

· REST

· JSON

· ATOM Feed

Just working with this new approach, with sample applications.
We may interested with publically deployed any existing "ADO.NET Data services", one of the example http://stevef.goes.com/northwindservice/NorthwindService.svc/

some useful links regarding this,

MSDN : Using ADO.NET Data Services
http://msdn.microsoft.com/en-us/library/cc907912.aspx

MSDN : Overview of ADO.NET Data Services
http://msdn.microsoft.com/en-gb/library/cc956153.aspx

Astoria Team Blog
http://blogs.msdn.com/astoriateam/

NOTE: for developing application in this, minimum we need

Visual Studio 2008 SP1
.NET Framework 3.5 SP1

Hope soon I will update here with more details about this.

Windows Vista : My User Profile Corrupted

2009-01-25T15:31:00.001+05:30

Currently am using Windows Vista SP1 with Updates.

Unfortunately, today morning my user profile got corrupted. [just before that, I was working with out problem and shut downed properly, but could in find the root for the cause].

While restarting, it was showing as “preparing your desktop” and then loaded a temporary profile :-( Shows the below error message,

Your user profile was not loaded correctly! You have been logged on with a temporary profile.

Changes you make to this profile will be lost when you log off. Please see the event log for details or contact your administrator.

Fortunately, my “user directory” is not deleted for my turn, at least that content was saved.

Timely got resolution for this problem in “Microsoft Support Portal”

http://support.microsoft.com/kb/947242

The excerpt of the solution

Log on to the system by using an administrative user account other than the user account that is experiencing the problem.
Back up all data in the current user's profile folder if the profile folder still exists, and then delete the profile folder. By default, the profile resides in the following location:
%SystemDrive%\Users\UserName
Click Start, type regedit in the Start Search box, and then press ENTER. Collapse this imageExpand this image
If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
Locate the following registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
Under the ProfileList subkey, delete the subkey that is named SID.bak.
Note SID is a placeholder for the security identifier (SID) of the user account that is experiencing the problem. The SID.bak subkey should contain a ProfileImagePath registry entry that points to the original profile folder of the user account that is experiencing the problem.
Exit Registry Editor.
Log off the system.
Log on to the system again.

After you log on to the system, the profile folder is re-created.

2008-12-01T23:50:00.000+05:30

Scott Hanselman wrote an interesting post about "How to find the location of the website visitors".

http://www.hanselman.com/blog/TheWeeklySourceCode37GeolocationGeotargetingReverseIPAddressLookupInASPNETMVCMadeEasy.aspx

Fast Abstract:

Many Paid solutions / services are available. In case of free available services, Scott is saying about, two approaches.

One: Server-side work: Using http://www.hostip.info/

If we are sending IP address to this site's API, they are returning an xml document with location information. It is community based one, user provided data.

Two: Client-side work: Using Google AJAX API

google.load("jquery", "1.2.6");

google.load("jqueryui", "1.5.2");

var yourLocation = google.loader.ClientLocation.address.city + ", "

+ google.loader.ClientLocation.address.region;

</script>

Just need to do simple registration from google site. This is working fine, yes, for me provided my ip location correctly.

And If you find any further solutions OR updated information on this, please let me know via ‘comments’.

Fun with Visual Studio : in my mother tongue too

2008-11-16T07:10:00.000+05:30

Captions Language Interface Pack for Microsoft Visual Studio 2008 (even working fine for other applications also)

Captions Language Interface Pack (CLIP) is a simple language translation, uses tooltip captions to display translations for English user interface terms.

Now, CLIP for Visual Studio 2008 is available in Arabic, Czech, Hebrew, Hindi, Malayalam, Oriya, Polish, Tamil and Turkish.

From Scott,

It'll even help with other applications within Windows if it thinks it's got a decent translation, but for now, it is focused on correct translation for common Visual Studio options.

Care about “Create Table AS Select” statement

2008-11-11T22:20:00.000+05:30

Hi folks,

I had one misassumption on the SQL statement CREATE TABLE AS SELECT in database operations. We are using this form of statement for creating a table from an existing table.

Ex. Create table New_tab as select * from Old_tab;

Yes, it is working, table creation is done. But, what I thought about it is, it will create that new_tab table with constraints & index which are available in old_tab. But, only table is created with the values (if any exists) ; constrains, primary key & index are not created for the new_tab table, even they are present in old_tab. I tried this in MySQL.

It seems this not only for MySQL, I will check any option needs to provide, to get result as expected.

If anyone have any suggestions / content about this, update me.

Today (07-Oct-2008), it’s different.

Several personal decisions, thoughts.

[ .. .. ... ]

And, it is first time, here am writing, about office incident.

“Jinson Jose”, my colleague, is moving to another assignment, and hence moving to another team.

Being with him, was just few days, because only few days before we joined both in same task, but these days are different.

He haven’t tried to dominate,

not avoided his work & pushing to others to make them as victims.

He shared the tasks, shared the knowledge for that task.

He is willing to share.

And in work he is perfect. He is doing the same assigned task, but in different manner.

Hope and wish him, to continue his excellence ever.

Web21C SDK is joining Ribbit!

2008-09-25T22:09:00.002+05:30

Today, i received an important information about "BT Web21C SDK". Herebelow am sharing this with you.

Announcement from "Mr JP Rangaswami (Managing Director, Strategy & Innovation, BT Design)

Dear Web21C SDK Developer,

BT has consistently supported the vision of an open, programmable telephony platform through its investment in its award winning Web21C SDK initiative. BT's vision has been to enable global innovation by giving software developers the tools they need to creatively embed voice into high-value business and personal processes through software applications. BT's goal has been to enable developers to build communications solutions that our customers want and need, as they define them, today and into the future.

Supporting our vision and goal, BT announced on 29 July that it acquired Ribbit Corporation (www.ribbit.com), underpinning our ongoing commitment and belief that voice can be integrated, personalised and monetised by developers everywhere for both enterprises and consumers, bringing to life new ideas, new experiences and new business models.

Complementing the server side tools provided by our Web21C SDK, Ribbit brings a host of client side features that will enable you to bring together voice calling and Web 2.0 experiences, turning voice into a rich feature that can be added to any application, on any device.

Ribbit's client-based API is currently based on Adobe Flash and Flex components and libraries. This API allows a web programmer or designer to access Ribbit's capabilities directly through a web page in a browser or in the case of Adobe's AIR technology, as a entirely standalone application. Ribbit is also in the process of extending its client-based APIs to Microsoft's .NET/Silverlight and Sun's JavaFX.

For more information on Ribbit's current set of APIs, which include, calling, the ability to play and record audio files and phrases, transcription of voice, access to directory listings, the ability to create, provision, and access user data and many, many more, go to http://developer.ribbit.com

We are also in the process of migrating the Web21C SDK into Ribbit, providing you with the same server-side APIs which allow machine-to-machine communication. Supporting this migration, Ribbit will provide a REST-based API in December 2008. On top of this API, Ribbit or third parties can add numerous server language bindings including Python, Perl, Java, Ruby, and others.

To ensure a smooth transition and to focus on efforts on providing you with the REST API as soon as possible, we will be suspending the Web21C SDK platform at 12:00 pm GMT on Friday, 10 October.

In the meantime, come and play at Ribbit! If you haven't already, go to http://developer.ribbit.com and sign up for a developer account, giving you immediate access to all the benefits already shared by the over 6,000 Ribbit developer community members including comprehensive documentation and code samples to help you "Ribbitize" your application!

As a member, you'll be able to create and share your Ribbit applications, get feedback from other developers and see what others are building. You'll also be able to participate in the community forums, where you'll receive first hand support from the Ribbit team. Additional support can be found at developersupport@ribbit.com. Contact us with your questions and we will be happy to address your needs and get you coding with Ribbit!

We look forward to enhancing your development efforts with Ribbit and we would like to thank you and your involvement with the Web21C SDK. We are excited about the opportunities ahead and look forward to your continued support during this transition, as we continue to provide you with more tools to allow you to innovate with voice and communications.

Analysing Elements of Any Webpage

2008-07-23T22:17:00.004+05:30

Hi All,

Here below details about: How to analyse Website elements using Tools.

IE Browser - Internet Explorer Developer Toolbar
Firebox Browser - Firebug plug-in

Even few months before came to know about “Internet Explorer DEVELOPER Toolbar”, yesterday only I downloaded and installed. Really it will be helpful to analyse the parts of webpage.

Usages briefly,

Explore and modify the document object model (DOM) of a Web page.
Locate and select specific elements on a Web page through a variety of techniques.
View HTML object class names, ID's, and details such as link paths, tab index values
Outline tables, table cells, images, or selected tags.
Validate HTML, CSS, WAI, and RSS web feed links.

Link download

http://www.microsoft.com/downloadS/details.aspx?familyid=E59C3964-672D-4511-BB3E-2D5E1DB91038&displaylang=en

Likewise, In Firebox, we can download and add a plug-in "FireBug". It is also having many more functionality (yes, i used only basic functionalies). currently am working on Firebox version 3. In this by default, this plugin is available.

In Internet Explorer 8 beta, IE developer tool is also coming as out of box.

So, go and explore any website, its properties....

Predictions for the year 2008

2008-01-08T13:46:00.002+05:30

Hi All,

I got an article about "Predictions for the year 2008" from Mr. Balasubramanian Venkatraman. He is a Lecturer, Department of Computer Science, Bharathidasan University, Trichy, Tamil Nadu, India.

Here that article is published for your view.

31-Dec-2007
Balasubramanian Venkatraman wrote:

Dear friends

Greetings!

Happy New Year!

This is my way of saying Happy new year to you. I want to analyze the technical scenario of 2007 and my predictions for the year 2008. Since you are all tech savvy, I just wanted to share some information to you. Please go through and provide your feed backs.

The year 2007 was a good one. The IT job market was stable. Mankind got an iPhone. While there were not any revolutionary changes in the way software was developed, I believe that this was a year of rich Internet applications and Web 2.0. YouTube became a part of the lives of millions of people around the world. A large portion of the population visits orkut daily. What's next? What language/tool/technique to learn? What's the next big thing in IT? Though elders like me are also using orkut, it has been declared as an youth icon of the year 2007 by MTV. (?!)

In my opinion……..

1. Java will remain strong in large enterprises, but will continue losing ground as a development platform for small businesses. J2EE is way too heavy, and scripting languages and frameworks offer an alternative and productive way of software development when the cost of development is more important than performance and scalability. The LAMP platform will remain a preferable way to develop applications for small to medium businesses.

2. AJAX popularity may go downhill. I have red a number of articles in blogs which say AJAX is not
a good choice for developing enterprise applications. But the vast majority of the software world was (and still is) marching the AJAX way. This time it's more of a hope than a prediction that in 2008 people will realize that AJAX should serve the same goal as JavaScript – making your Web pages a little prettier. Expect to see the re-branding of some of the AJAX frameworks into RIA or Web 2.0 solutions.

3. Speaking of Web 2.0… Even though Web 2.0 was not officially defined, I think it's all about giving more control to the users of the Web sites. The more interactive a Web site is, the higher the number people will put in front of the zero – 3.0, 4.0, and so on. Some people say that Web 3.0 is about Semantic Web. If you bought a grill on Amazon.com, they can guess with high probability that you might be shopping for rib-eye steaks. Check it out the next time you visit the site. It's all about control. From the user's side and from the vendor's side. We'll see more and more interactive sites next year. While some people are planning to write next-generation sophisticated software, others will come up with a very simple, easy-to-implement but appealing business idea, and the next 20-year billionaire is born. As someone who reads anything if it contains a string "semantic web", I believe semantic web is not web 3.0

4. Flash Player will remain the best deployment platform for rich Internet applications. While Microsoft is trying to come up with a competitive delivering platform for RIA, it's not going to happen in 2008. Silverlight 1.0 is a good start, the next version (1.1) will be even better, but it'll take time to release a product that can do more than streaming multimedia.

5. Ruby on Rails will take a small share of the market of small non-mission-critical Web applications. Convention over configuration. Speed of development over performance. While Ruby on Rails will not become a framework of choice, it has achieved a very positive result – people have started to realize that not every project has to be developed in either Java or .NET. Besides, RoR is a well-designed framework that will become a good design sample for the new frameworks of the future.

6. Internet video and television will be booming and I'm not talking about YouTube. Internet Video will start being a part of a number of enterprise applications. This process won't be fast, and you have an opportunity to be among the early adopters in this sector.

7. Outsourcing will gain more and more ground despite the fact that it's very expensive and the project failure rate is high. The reason is that the U.S. has almost stopped producing software engineers. It's just a matter of time before everyone gets used to the fact that business software is made in India, just like we all know that all toys (with or without lead) are made in China. But innovation in software will still be happening in America. I guess, there's something in the air here. Re-read an old but valid article by Paul Graham about why Silicon Valley can't be exported.

8. Apple - next year I'll finally purchase a MacBook Pro or sony vaio for myself… if our Toshiba satellite and tecra will die. Peer pressure, a cool design and the ability to run Windows (plan B),will force me to ignore the high price.

9. Telephony. If 2007 was the year of Skype, we'll see some interesting development in this area. Skype is a great product, but it requires you to download and install software. In the era of RIA, things can be done without it. Watch the Ribbit phone software that will allow you to make calls and receive e-mails just from your Web browser.

10. IT job market. ( I am sorry yarr I also pray to God, that this should not happen) While we've enjoyed a stable demand for IT professionals in 2007, it won't last and next year we'll see project freezes and even layoffs. The reason is the burst of the real estate bubble. This will affect not only those simple people who were brainwashed and decided that they could have afforded an American dream. CEOs of major Wall Street, UK, Bangalore, Chennai, Hyd corporations are being fired after drowning their companies by getting into bad mortgage debt. Among other things, the IT budget will be severely cut. As you know, today on Wall Street, is tomorrow on Main street. Use the training budget of your employer now if it's not too late. Keep your skills up to date.

11. The hottest IT skills of 2008. When the job market is tight, recruiters immediately increase the list of skill requirements for job openings. You'll see job postings that expect you to know a number of programming languages ranging from Cobol to C++. Knowing just one hot tool does not cut it anymore. But if you have limited time and need money, start by learning tools for developing rich Internet applications. The skill set of a highly paid Web developer, at a minimum, has to include the following skills:
HTML,CSS, JavaScript, J2EE or.NET, Flex or Silverlight, AJAX, and good communication skills. You do not have to really learn AJAX, but must add AJAX keyword to your resume, otherwise you may not even get a job interview.

12. The next big thing. Software development will change to a wider use of code generators. Forget about heavy frameworks, regardless of what programming language you use. In a simple case, use some XML style sheets combined with the metadata that describes your application objects to automatically generate the code for these objects. On a larger scale, the entire application may be described using metadata and XML, and an appropriate code generator will do the job. So programming will change from writing tedious code that requires lots of coders to describing the metadata and writing custom code generators.

To say all the above things, I don't need much technical expertise, just watching some mash-ups like Google news, IT business edge, technology market watch, and the web site of the organization that sets the tone for the public policy for the Indian software industry, Nasscom.org.

Again I wish to say,

Happy New Year & Let this year bring a lot of prosperity to you, your family and to our country.

Regards,

Bala Venkat

"ADO.NET Parameter" usage : Order is matter with OLEDB provider

2007-10-30T18:56:00.000+05:30

While we are doing Data Manipulation using ADO.NET, "Parameter" objects for In/Out direction values, specified "Order of Parameters" is matter with OLEDB Provider.

In SQLServer Data Provider, parameters order is NOT a matter, parameters names are important.

For example: From "Emp" table, we need employees with Given Name and Given Salary.
to do this, we need to supply values for two parameters (Name and Salary)

...
...
OLEDBConnection con = new SQLConnection("give connection string here");

string strCommand= "select * from emp where Name=@Name and Salary=@Salary";

OLEDBCommand cmd = new OLEDBCommand(strCommand);
cmd.Connection = con;

OLEDBParameter paramName = new OLEDBParameter( );
paramName.ParameterName ="Name";
paramName.value = "Vignesh";
cmd.parameters.add(paramName);

OLEDBParameter paramSalary = new OLEDBParameter( );
paramSalary.ParameterName ="Salary";
paramSalary.value = "20o00";
cmd.parameters.add(paramSalary);

...
...
...

Here, we are doing with OLEDB Provider. In our example, we added parameter in the same order as in given query. So, it won't create problem.

OLEDB looking for ORDER of parameter, NOT for the parameter name. Check the parameter names given in the Query (they are @Name and @Salary) .

in coding : paramName.ParameterName ="Name"

even you change the parameter name as

paramName.ParameterName ="NOTName"

It won't be problem, we added that paramName as first in the cmd's parameters collection. so, take care about "order of parameters" while adding to Command object in OLEDB provider.

but in SQLSERVER Provider, parameter name is important, so paramObject.ParameterName must match with Parameter name which is given in the Query.

---

In one of my application, i was affected by this problem [ actually, problem was with me, even i know about OLEDB's behavior in Parameters, i found this issue only after 2 weeks ]

---

for other Data Providers [ Oracle provider and ODBC provider] i will verify and Update soon.
