Replace or recode several different values by a single value in an Excel file

- by Ali

Hi all, I have an Excel worksheet which contains data in several columns. For a specific column, I will need Excel to replace all values between, say 10 to 15, by the value 1 and values between 16 and 20 by the value 2 and so forth. I know how to do it for a single value; ie: I can replace value 10 by 1, 11 by 1 and so on. But this will be a tedious exercise. Are there some lines of codes that can execute this task? Thanks for your help. regards, Ali

Python script repeated auto start up.

- by Ali

I am designing a python web app, where people can have an email sent to them on a particular day. So a user puts in his emai and date in a form and it gets stored in my database. My script would then search through the database looking for all records of todays date, retrive the email, sends them out and deletes the entry from the table. Is it possible to have a setup, where the script starts up automatically at a give time, say 1 pm everyday, sends out the email and then quits? If I have a continuously running script, i might go over the CPU limit of my shared web hosting. Or is the effect negligible? Ali

ASP.Net GridView Sorting

- by Ali Shafai

I have a grid view with AllowSorting set to true. I get an event onsorting when a sortable header is clicked on. the handler has a parameter "GridViewSortEventArgs e" which has a SortDirection property on it. regardless of how many times you click on the same heading, the SortDirection is always Ascending. I think I'm missing something, like a way to tell the grid "now you are sorted based on column one and in ascending order", so that next time the grid sees a click on the "column one" heading, it decides to go descending. any help appreciated. Cheers, Ali

Implementing History Support using jQuery for AJAX websites built on asp.net AJAX

- by anil.kasalanati

Problem Statement: Most modern day website use AJAX for page navigation and gone are the days of complete HTTP redirection so it is imperative that we support back and forward buttons on the browser so that end users navigation is not broken. In this article we discuss about solutions which are already available and problems with them. Microsoft History Support: Post .Net 3.5 sp1 Microsoft’s Script manager supports history for websites using Update panels. This is achieved by enabling the ENABLE HISTORY property for the script manager and then the event “Page_Browser_Navigate” needs to be handled. So whenever the browser buttons are clicked the event is fired and the application can write code to do the navigation. The following articles provide good tutorials on how to do that http://www.asp.net/aspnet-in-net-35-sp1/videos/introduction-to-aspnet-ajax-history http://www.codeproject.com/KB/aspnet/ajaxhistorymanagement.aspx And Microsoft api internally creates an IFrame and changes the bookmark of the url. Unfortunately this has a bug and it does not work in Ie6 and 7 which are the major browsers but it works in ie8 and Firefox. And Microsoft has apparently fixed this bug in .Net 4.0. Following is the blog http://weblogs.asp.net/joshclose/archive/2008/11/11/asp-net-ajax-addhistorypoint-bug.aspx For solutions which are still running on .net 3.5 sp1 there is no solution which Microsoft offers so there is are two way to solve this o Disable the back button. o Develop custom solution. Disable back button Even though this might look like a very simple thing to do there are issues around doing this because there is no event which can be manipulated from the javascript. The browser does not provide an api to do this. So most of the technical solution on internet offer work arounds like doing a history.forward(1) so that even if the user clicks a back button the destination page redirects the user to the original page. This is not a good customer experience and does not work for asp.net website where there are different views in the same page. There are other ways around detecting the window unload events and writing code there. So there are 2 events onbeforeUnload and onUnload and we can write code to show a confirmation message to the user. If we write code in onUnLoad then we can only show a message but it is too late to stop the navigation. And if we write on onBeforeUnLoad we can stop the navigation if the user clicks cancel but this event would be triggered for all AJAX calls and hyperlinks where the href is anything other than #. We can do this but the website has to be checked properly to ensure there are no links where href is not # otherwise the user would see a popup message saying “you are leaving the website”. Believe me after doing a lot of research on the back button disable I found it easier to support it rather than disabling the button. So I am going to discuss a solution which work using jQuery with some tweaking. Custom Solution JQuery already provides an api to manage the history of a AJAX website - http://plugins.jquery.com/project/history We need to integrate this with Microsoft Page request manager so that both of them work in tandem. The page state is maintained in the cookie so that it can be passed to the server and I used jQuery cookie plug in for that – http://plugins.jquery.com/node/1386/release Firstly when the page loads there is a need to hook up all the events on the page which needs to cause browser history and following is the code to that. jQuery(document).ready(function() { // Initialize history plugin. // The callback is called at once by present location.hash. jQuery.history.init(pageload); // set onlick event for buttons jQuery("a[@rel='history']").click(function() { // var hash = this.page; hash = hash.replace(/^.*#/, ''); isAsyncPostBack = true; // moves to a new page. // pageload is called at once. jQuery.history.load(hash); return true; }); }); The above scripts basically gets all the DOM objects which have the attribute rel=”history” and add the event. In our test page we have the link button which has the attribute rel set to history. <asp:LinkButton ID="Previous" rel="history" runat="server" onclick="PreviousOnClick">Previous</asp:LinkButton> <asp:LinkButton ID="AsyncPostBack" rel="history" runat="server" onclick="NextOnClick">Next</asp:LinkButton> <asp:LinkButton ID="HistoryLinkButton" runat="server" style="display:none" onclick="HistoryOnClick"></asp:LinkButton> And you can see that there is an hidden HistoryLinkButton which used to send a sever side postback in case of browser back or previous buttons. And note that we need to use display:none and not visible= false because asp.net AJAX would disallow any post backs if visible=false. And in general the pageload event get executed on the client side when a back or forward is pressed and the function is shown below function pageload(hash) { if (hash) { if (!isAsyncPostBack) { jQuery.cookie("page", hash); __doPostBack("HistoryLinkButton", ""); } isAsyncPostBack = false; } else { // start page jQuery("#load").empty(); } } As you can see in case there is an hash in the url we are basically do an asp.net AJAX post back using the following statement __doPostBack("HistoryLinkButton", ""); So whenever the user clicks back or forward the post back happens using the event statement we provide and Previous event code is invoked in the code behind. We need to have the code to use the pageId present in the url to change the page content. And there is an important thing to note – because the hash is worked out using the pageId’s there is a need to recalculate the hash after every AJAX post back so following code is plugged in function ReWorkHash() { jQuery("a[@rel='history']").unbind("click"); jQuery("a[@rel='history']").click(function() { // var hash = jQuery(this).attr("page"); hash = hash.replace(/^.*#/, ''); jQuery.cookie("page", hash); isAsyncPostBack = true; // moves to a new page. // pageload is called at once. jQuery.history.load(hash); return true; }); } This code is executed from the code behind using ScriptManager RegisterClientScriptBlock as shown below – ScriptManager.RegisterClientScriptBlock(this, typeof(_Default), "Recalculater", "ReWorkHash();", true); A sample application is available to be downloaded at the following location – http://techconsulting.vpscustomer.com/Source/HistoryTest.zip And a working sample is available at – http://techconsulting.vpscustomer.com/Samples/Default.aspx

Enabling Http caching and compression in IIS 7 for asp.net websites

- by anil.kasalanati

Caching – There are 2 ways to set Http caching 1- Use Max age property 2- Expires header. Doing the changes via IIS Console – 1. Select the website for which you want to enable caching and then select Http Responses in the features tab 2. Select the Expires webcontent and on changing the After setting you can generate the max age property for the cache control 3. Following is the screenshot of the headers Then you can use some tool like fiddler and see 302 response coming from the server. Doing it web.config way – We can add static content section in the system.webserver section <system.webServer> <staticContent> <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="365.00:00:00" /> </staticContent> Compression - By default static compression is enabled on IIS 7.0 but the only thing which falls under that category is CSS but this is not enough for most of the websites using lots of javascript. If you just thought by enabling dynamic compression would fix this then you are wrong so please follow following steps – In some machines the dynamic compression is not enabled and following are the steps to enable it – Open server manager Roles > Web Server (IIS) Role Services (scroll down) > Add Role Services Add desired role (Web Server > Performance > Dynamic Content Compression) Next, Install, Wait…Done! ? Roles > Web Server (IIS) ? Role Services (scroll down) > Add Role Services Add desired role (Web Server > Performance > Dynamic Content Compression) Next, Install, Wait…Done! Enable - ? Open server manager ? Roles > Web Server (IIS) > Internet Information Services (IIS) Manager Next pane: Sites > Default Web Site > Your Web Site Main pane: IIS > Compression Then comes the custom configuration for encrypting javascript resources. The problem is that the compression in IIS 7 completely works on the mime types and by default there is a mismatch in the mime types Go to following location C:\Windows\System32\inetsrv\config Open applicationHost.config The mimemap is as follows <mimeMap fileExtension=".js" mimeType="application/javascript" /> So the section in the staticTypes should be changed <add mimeType="application/javascript" enabled="true" /> Doing the web.config way – We can add following section in the system.webserver section <system.webServer> <urlCompression doDynamicCompression="false" doStaticCompression="true"/> More Information/References – · http://weblogs.asp.net/owscott/archive/2009/02/22/iis-7-compression-good-bad-how-much.aspx · http://www.west-wind.com/weblog/posts/98538.aspx

Debugging OWB generated SAP ABAP code executed through RFC

- by Anil Menon

Within OWB if you need to execute ABAP code using RFC you will have to use the SAP Function Module RFC_ABAP_INSTALL_AND_RUN. This function module is specified during the creation of the SAP source location. Usually in a Production environment a copy of this function module is used due to security restrictions. When you execute the mapping by using this Function Module you can’t see the actual ABAP code that is passed on to the SAP system. In case you want to take a look at the code that will be executed on the SAP system you need to use a custom Function Module in SAP. The easiest way to do this is to make a copy of the Function Module RFC_ABAP_INSTALL_AND_RUN and call it say Z_TEST_FM. Then edit the code of the Function Module in SAP as below FUNCTION Z_TEST_FM . DATA: BEGIN OF listobj OCCURS 20. INCLUDE STRUCTURE abaplist. DATA: END OF listobj. DATA: begin_of_line(72). DATA: line_end_char(1). DATA: line_length type I. DATA: lin(72). loop at program. append program-line to WRITES. endloop. ENDFUNCTION. Within OWB edit the SAP Location and use Z_TEST_FM as the “Execution Function Module” instead of RFC_ABAP_INSTALL_AND_RUN. Then register this location. The Mapping you want to debug will have to be deployed. After deployment you can right click the mapping and click on “Start”. After clicking start the “Input Parameters” screen will be displayed. You can make changes here if you need to. Check that the parameter BACKGROUND is set to “TRUE”. After Clicking “OK” the log for the execution will be displayed. The execution of Mappings will always fail when you use the above function module. Clicking on the icon “I” (information) the ABAP code will be displayed. The ABAP code displayed is the code that is passed through the Function Module. You can also find the code by going through the log files on the server which hosts the OWB repository. The logs will be located under <OWB_HOME>/owb/log. Patch #12951045 is recommended while using the SAP Connector with OWB 11.2.0.2. For recommended patches for other releases please check with Oracle Support at http://support.oracle.com

Simple way of converting server side objects into client side using JSON serialization for asp.net websites

- by anil.kasalanati

Introduction:- With the growth of Web2.0 and the need for faster user experience the spotlight has shifted onto javascript based applications built using REST pattern or asp.net AJAX Pagerequest manager. And when we are working with javascript wouldn’t it be much better if we could create objects in an OOAD way and easily push it to the client side. Following are the reasons why you would push the server side objects onto client side - Easy availability of the complex object. - Use C# compiler and rick intellisense to create and maintain the objects but use them in the javascript. You could run code analysis etc. - Reduce the number of calls we make to the server side by loading data on the pageload. I would like to explain about the 3rd point because that proved to be highly beneficial to me when I was fixing the performance issues of a major website. There could be a scenario where in you be making multiple AJAX based webrequestmanager calls in order to get the same response in a single page. This happens in the case of widget based framework when all the widgets are independent but they need some common information available in the framework to load the data. So instead of making n multiple calls we could load the data needed during pageload. The above picture shows the scenario where in all the widgets need the common information and then call GetData webservice on the server side. Ofcourse the result can be cached on the client side but a better solution would be to avoid the call completely. In order to do that we need to JSONSerialize the content and send it in the DOM. Example:- I have developed a simple application to demonstrate the idea and I would explaining that in detail here. The class called SimpleClass would be sent as serialized JSON to the client side . And this inherits from the base class which has the implementation for the GetJSONString method. You can create a single base class and all the object which need to be pushed to the client side can inherit from that class. The important thing to note is that the class should be annotated with DataContract attribute and the methods should have the Data Member attribute. This is needed by the .Net DataContractSerializer and this follows the opt-in mode so if you want to send an attribute to the client side then you need to annotate the DataMember attribute. So if I didn’t want to send the Result I would simple remove the DataMember attribute. This is default WCF/.Net 3.5 stuff but it provides the flexibility of have a fullfledged object on the server side but sending a smaller object to the client side. Sometimes you may hide some values due to security constraints. And thing you will notice is that I have marked the class as Serializable so that it can be stored in the Session and used in webfarm deployment scenarios. Following is the implementation of the base class – This implements the default DataContractJsonSerializer and for more information or customization refer to following blogs – http://softcero.blogspot.com/2010/03/optimizing-net-json-serializing-and-ii.html http://weblogs.asp.net/gunnarpeipman/archive/2010/12/28/asp-net-serializing-and-deserializing-json-objects.aspx The next part is pretty simple, I just need to inject this object into the aspx page. And in the aspx markup I have the following line – <script type="text/javascript"> var data =(<%=SimpleClassJSON %>); alert(data.ResultText); </script> This will output the content as JSON into the variable data and this can be any element in the DOM. And you can verify the element by checking data in the Firebug console. Design Consideration – If you have a lot of javascripts then you need to think about using Script # and you can write javascript in C#. Refer to Nikhil’s blog – http://projects.nikhilk.net/ScriptSharp Ensure that you are taking security into consideration while exposing server side objects on to client side. I have seen application exposing passwords, secret key so it is not a good practice. The application can be tested using the following url – http://techconsulting.vpscustomer.com/Samples/JsonTest.aspx The source code is available at http://techconsulting.vpscustomer.com/Source/HistoryTest.zip

Video Training Courses for Linux/Ubuntu?

- by Anil

I'm a software developer with more than 15 years of experience on Windows platform, focused on C#/.NET/SQL Server stack. Recently I decided to explore Linux and learn a new development technology stack which is completely unrelated to Microsoft. After a bit of (re)search/reading I picked Ubuntu as my starting point. As I'm really a Pluralsight addict, preferring video courses as a starting point for learning new stuff, I wanted to ask if there are any decent video courses for Linux generally or Ubuntu focused ones? Basically I'm searching for general explanation of OS structure, a bit of system administration, and maybe some considerations for development on Linux system.

I also have all other public files (images, js, css, etc.) under the public folder. Here, I also have a wordpress blog under the "blog" folder. There's an empty test folder too The Problem When I go to mydomain.com/blog, I get redirected to http://www.theredpin.com/blog (correctly), then to http://www.theredpin.com/blog/ (just with an extra / at end), finally to http://theredpin.com/blog/ -- and we're back where we started. The loop continues. What I don't understand is why would wordpress try to remove the www? I'm guessing it's wordpress because my empty test folder acts just fine! PLEASE HELP. I"M REALLY DESPERATE :( Thank you very much Other things that happen: When I go to mydomain.com, i correctly get redirected to www.mydomain.com When I go to www.mydomain.com, i correctly stay where I am When I go to www.mydomain.com/test or mydomain.com/test, behaviour is correct. Setup So my .htaccess file does the following: If there's no www., then add it and do a 301 redirect. Here's the code I use RewriteCond %{HTTP_HOST} ^mydomain.com [NC] RewriteRule ^(.*)$ http://www.mydomain.com/$1 [L,R=301] If the request is NOT for a resource (image, etc.), or the blog, then load zend application by rewriting to index.php RewriteRule !((^blog(/)?.*$)|(.(js|ico|gif|jpg|jpeg|png|css|cur|JPG|html|txt))$) index.php Thanks again for all your help!!!

I want to display inline content using Thickbox (Eventually I will be displaying a PDF in an iframe). I have included all the javascript and css files etc. and referenced them as in code below. <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="JQueryLearning._Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Untitled Page</title> <script src="Scripts/thickbox.js" type="text/javascript"></script> <script src="Scripts/thickbox-compressed.js" type="text/javascript"></script> <script src="Scripts/jquery-1.4.2.min.js" type="text/javascript"></script> <link href="App_Themes/Theme/Css/thickbox.css" rel="stylesheet" type="text/css" /> </head> <body> <form id="form1" runat="server"> <div> <a href="#TB_inline?height=50&width=300&inlineId=hiddenModalContent" title="Simple Demo" class="thickbox">Show hidden content.</a> <div id="hiddenModalContent" style="display: none;"> <div style="text-align: center;"> Hello ThickBox!</div> </div> </div> </form> </body> </html> Am I missing something?

Cannot cause $(this).find("a").click(); to fire using JQuery

- by Ali

Hi Everyone, I have a small question which should be very easy for the jquery experts out there. I am trying to follow http://aspdotnetcodebook.blogspot.com/2010/01/page-languagec-autoeventwireuptrue.html to be able to perform an action on gridview row double click. I can redirect to another page fine (as shown in the example) but I cannot cause the $(this).find("a").click(); to fire. Below is my GridView markup. <asp:GridView ID="gvCustomers" runat="server" DataSourceID="odsCustomers" CssClass="datagrid" GridLines="None" AutoGenerateColumns="False" DataKeyNames="Customer_ID" PageSize="3" AllowPaging="True" AllowSorting="True" OnRowCommand="gvCustomers_RowCommand" OnRowDataBound="gvCustomers_RowDataBound"> <Columns> <asp:BoundField DataField="Customer_ID" HeaderText="ID" ReadOnly="true" Visible="false" /> <asp:BoundField DataField="Customer_FirstName" HeaderText="First Name" ReadOnly="true" /> <asp:BoundField DataField="Customer_LastName" HeaderText="Last Name" ReadOnly="true" /> <asp:BoundField DataField="Customer_Email" HeaderText="Email" ReadOnly="true" /> <asp:BoundField DataField="Customer_Mobile" HeaderText="Mobile" ReadOnly="true" /> <asp:TemplateField> <ItemTemplate> <asp:LinkButton ID="lnkButton" runat="server" CommandName="showVehicles" CommandArgument='<%# Eval("Customer_ID") %>' ></asp:LinkButton> </ItemTemplate> </asp:TemplateField> </Columns> <EmptyDataTemplate> Sorry No Record Found. </EmptyDataTemplate> </asp:GridView> I just cant make it work as the author has suggested: /* or you could have a hidden LinkButton in the row (Text="" or not set) that you could trigger. Make sure you set the CommandName="Something" and CommandArgument="RecordId" */ on the OnCommand of linkButton, I have my server side method which I would like to fire. Any ideas will be most apprecited. Thanks, Ali

how to combine widget webapp framework with SEO-friendly CSS and JS files

- by Ali

Hi guys, I'm writing a webapp using Zend framework and a homebrew widget system. Every widget has a controller and can choose to render one of many views if it chooses. This really helps us modularize and reconfigure and reuse the widgets anywhere on the site. The Problem is that the views of each widget contain their own JS and CSS code, which leads to very messy HTML code when the whole page is put together. You get pockets of style and script tags everywhere. This is bad for a lot of different reasons as I'm sure you know, but it has a profound effect on our SEO as well. Several solutions that I've been able to come up with: Separate the CSS and JS of every view of every widget into its own file - this has serious drawbacks for load times (many more resources have to be loaded separately) and it makes coding very difficult as now you have to have 3-4 files open just to edit a widget. combine the all the widget CSS into a single file (same with JS) - would also lead to a massive load when someone enters the site, mixes up the CSS and the JS for all widgets so it's harder to keep track of them, and other problems that I'm sure you can think of. Create a system that uses method 1 (separate CSS and JS for every widget), when delivering the page, stitches all CSS and JS together. This obviously needs more processing time and of course the creation of such a system, etc. My Question is what you guys think of these solutions or if there are pre-existing solutions that you know of (or any tech that might help) solve this problem. I really appreciate all of your thoughts and comments!! Thanks guys, Ali

Scala programming language for beginners, is it a legend?

- by ali

Hi every one, I am Ali from Saudi Arabia. undoubtedly, Scala is one of the best programming language for any programmer to learn, but there is "good" problems that is faced especially by beginners, and what seems frustrating that these problems won't solve soon, so as a beginner and on behalf of beginners let me raise these "objective" questions: 1- why scala has no effective and stable development platform, in fact, it suffers many problems with Eclipse, Netbeat, and Intellij. 2- although I have looked for a clear,easy, and understandable explanation of how to get started with Scala, but fortunately, there was no article or guide that deserves to spend the time I have spent to read it. nobody could tell you clear steps that fit you as a beginner who wants to start his"HELLO WORLD" with Scala, while all other languages have its "HELLO WORLD" guides and books. thank you for your time, be sure that you read notes below. 1- I have no experience in programming language before. 2- don't tell me "not to begin with scala", simply, because I will do. 3- OS is windows vista home premium. 4- I hate excuses, such as Scala is new language......etc

SQL SERVER – Beginning of SQL Server Architecture – Terminology – Guest Post

- by pinaldave

SQL Server Architecture is a very deep subject. Covering it in a single post is an almost impossible task. However, this subject is very popular topic among beginners and advanced users. I have requested my friend Anil Kumar who is expert in SQL Domain to help me write a simple post about Beginning SQL Server Architecture. As stated earlier this subject is very deep subject and in this first article series he has covered basic terminologies. In future article he will explore the subject further down. Anil Kumar Yadav is Trainer, SQL Domain, Koenig Solutions. Koenig is a premier IT training firm that provides several IT certifications, such as Oracle 11g, Server+, RHCA, SQL Server Training, Prince2 Foundation etc. In this Article we will discuss about MS SQL Server architecture. The major components of SQL Server are: Relational Engine Storage Engine SQL OS Now we will discuss and understand each one of them. 1) Relational Engine: Also called as the query processor, Relational Engine includes the components of SQL Server that determine what your query exactly needs to do and the best way to do it. It manages the execution of queries as it requests data from the storage engine and processes the results returned. Different Tasks of Relational Engine: Query Processing Memory Management Thread and Task Management Buffer Management Distributed Query Processing 2) Storage Engine: Storage Engine is responsible for storage and retrieval of the data on to the storage system (Disk, SAN etc.). to understand more, let’s focus on the following diagram. When we talk about any database in SQL server, there are 2 types of files that are created at the disk level – Data file and Log file. Data file physically stores the data in data pages. Log files that are also known as write ahead logs, are used for storing transactions performed on the database. Let’s understand data file and log file in more details: Data File: Data File stores data in the form of Data Page (8KB) and these data pages are logically organized in extents. Extents: Extents are logical units in the database. They are a combination of 8 data pages i.e. 64 KB forms an extent. Extents can be of two types, Mixed and Uniform. Mixed extents hold different types of pages like index, System, Object data etc. On the other hand, Uniform extents are dedicated to only one type. Pages: As we should know what type of data pages can be stored in SQL Server, below mentioned are some of them: Data Page: It holds the data entered by the user but not the data which is of type text, ntext, nvarchar(max), varchar(max), varbinary(max), image and xml data. Index: It stores the index entries. Text/Image: It stores LOB ( Large Object data) like text, ntext, varchar(max), nvarchar(max), varbinary(max), image and xml data. GAM & SGAM (Global Allocation Map & Shared Global Allocation Map): They are used for saving information related to the allocation of extents. PFS (Page Free Space): Information related to page allocation and unused space available on pages. IAM (Index Allocation Map): Information pertaining to extents that are used by a table or index per allocation unit. BCM (Bulk Changed Map): Keeps information about the extents changed in a Bulk Operation. DCM (Differential Change Map): This is the information of extents that have modified since the last BACKUP DATABASE statement as per allocation unit. Log File: It also known as write ahead log. It stores modification to the database (DML and DDL). Sufficient information is logged to be able to: Roll back transactions if requested Recover the database in case of failure Write Ahead Logging is used to create log entries Transaction logs are written in chronological order in a circular way Truncation policy for logs is based on the recovery model SQL OS: This lies between the host machine (Windows OS) and SQL Server. All the activities performed on database engine are taken care of by SQL OS. It is a highly configurable operating system with powerful API (application programming interface), enabling automatic locality and advanced parallelism. SQL OS provides various operating system services, such as memory management deals with buffer pool, log buffer and deadlock detection using the blocking and locking structure. Other services include exception handling, hosting for external components like Common Language Runtime, CLR etc. I guess this brief article gives you an idea about the various terminologies used related to SQL Server Architecture. In future articles we will explore them further. Guest Author The author of the article is Anil Kumar Yadav is Trainer, SQL Domain, Koenig Solutions.
