How to redirect our Custom Error Page

In IIS 6 Select Your web site--> Go to Custom Error Tab --> Select Error Code -->Edit Property --> Set Your Error Page
In IIS 7 Select Your Web site --> Feature View --> Error Page --> Select Error Code –->Edit –->Set your Custom Error Page

Custom Control or User Control

Most of the developer knows, how to implement the Custom Control or User Control an ASP.NET Page. we have well experience in using the directive tag.

if we need to use the Custom Control or User Control on numbers of pages, it is possible to register in web.config file. It is reduce the redundancy code and we don’t need to implement the directives.


the web.config section is
<-controls->
<-add src="~/Controls/FlashNews.ascx" tagprefix="skm" tagname=" FlashNews "->
<-controls->


Once we register the control here we can access the User Control on number of pages using following syntax

skm:flashnews id="cusFlash" runat="server" cssclass="small-tab"/

Integrate PHP application to Microsoft IIS server

1.Download file from here http://www.atksolutions.com/articles/php_ver5.2.3.zip
2.Install your file to here c:/PHP
3.Open IIS 7.0 Manager -> Default Website -> Properties -> Home Directory -> Configuration -> Add -> php5isapi.dll -> ok
4.Copy php.ini file and paste to c:/Windows
5.Reboot System
6.Now check PHP is working in IIS server

Stored Procedure Optimization

Stored Procedures Optimization

• Use stored procedures instead of heavy-duty queries.
  This can reduce network traffic, because your client will send to server only stored procedure name (perhaps with some parameters) instead of large heavy-duty queries text. Stored procedures can be used to enhance security and conceal underlying data objects also. For example, you can give the users permission to execute the stored procedure to work with the restricted set of the columns and data.

• Include the SET NOCOUNT ON statement into your stored procedures to stop the message indicating the number of rows affected by a Transact-SQL statement.
  This can reduce network traffic, because your client will not receive the message indicating the number of rows affected by a Transact-SQL statement.

• Call stored procedure using its fully qualified name.
  The complete name of an object consists of four identifiers: the server name, database name, owner name, and object name. An object name that specifies all four parts is known as a fully qualified name. Using fully qualified names eliminates any confusion about which stored procedure you want to run and can boost performance because SQL Server has a better chance to reuse the stored procedures execution plans if they were executed using fully qualified names.

• Consider returning the integer value as an RETURN statement instead of an integer value as part of a recordset.
  The RETURN statement exits unconditionally from a stored procedure, so the statements following RETURN are not executed. Though the RETURN statement is generally used for error checking, you can use this statement to return an integer value for any other reason. Using RETURN statement can boost performance because SQL Server will not create a recordset.

• Don't use the prefix "sp_" in the stored procedure name if you need to create a stored procedure to run in a database other than the master database.
  The prefix "sp_" is used in the system stored procedures names. Microsoft does not recommend to use the prefix "sp_" in the user-created stored procedure name, because SQL Server always looks for a stored procedure beginning with "sp_" in the following order: the master database, the stored procedure based on the fully qualified name provided, the stored procedure using dbo as the owner, if one is not specified. So, when you have the stored procedure with the prefix "sp_" in the database other than master, the master database is always checked first, and if the user-created stored procedure has the same name as a system stored procedure, the user-created stored procedure will never be executed.

• Use the sp_executesql stored procedure instead of the EXECUTE statement.
  The sp_executesql stored procedure supports parameters. So, using the sp_executesql stored procedure instead of the EXECUTE statement improve readability of your code when there are many parameters are used. When you use the sp_executesql stored procedure to executes a Transact-SQL statements that will be reused many times, the SQL Server query optimizer will reuse the execution plan it generates for the first execution when the change in parameter values to the statement is the only variation.

• Use sp_executesql stored procedure instead of temporary stored procedures.
  Microsoft recommends to use the temporary stored procedures when connecting to earlier versions of SQL Server that do not support the reuse of execution plans. Applications connecting to SQL Server 7.0 or SQL Server 2000 should use the sp_executesql system stored procedure instead of temporary stored procedures to have a better chance to reuse the execution plans.

• If you have a very large stored procedure, try to break down this stored procedure into several sub-procedures, and call them from a controlling stored procedure.
  The stored procedure will be recompiled when any structural changes were made to a table or view referenced by the stored procedure (for example, ALTER TABLE statement), or when a large number of INSERTS, UPDATES or DELETES are made to a table referenced by a stored procedure. So, if you break down a very large stored procedure into several sub-procedures, you get chance that only a single sub-procedure will be recompiled, but other sub-procedures will not.

• Try to avoid using temporary tables inside your stored procedure.
  Using temporary tables inside stored procedure reduces the chance to reuse the execution plan.

• Try to avoid using DDL (Data Definition Language) statements inside your stored procedure.
  Using DDL statements inside stored procedure reduces the chance to reuse the execution plan.

• Add the WITH RECOMPILE option to the CREATE PROCEDURE statement if you know that your query will vary each time it is run from the stored procedure.
  The WITH RECOMPILE option prevents reusing the stored procedure execution plan, so SQL Server does not cache a plan for this procedure and the procedure is recompiled at run time. Using the WITH RECOMPILE option can boost performance if your query will vary each time it is run from the stored procedure because in this case the wrong execution plan will not be used.

• Use SQL Server Profiler to determine which stored procedures has been recompiled too often.
  To check the stored procedure has been recompiled, run SQL Server Profiler and choose to trace the event in the "Stored Procedures" category called "SP:Recompile". You can also trace the event "SP:StmtStarting" to see at what point in the procedure it is being recompiled. When you identify these stored procedures, you can take some correction actions to reduce or eliminate the excessive recompilations.

Add Script Handler to IIS 7(Vista) for Ajax Control Tool Kit

If Ajax Control toolkit is not working in IIS7 or Windows Vista, Verify the Http Handler in web configuration file

"httpHandlers"
"add path="ScriptResource.axd" verb="GET,HEAD" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/"
"/httpHandlers"

If Configuration file is fine,Add the following handler to IIS Handler Mappting
IIS 7 - > Handler Mapping -> Add Managed Handler

Request Path: ScriptResource.axd
Type: System.Web.Handlers.ScriptResourceHandler
Verbs: GET,POST,HEAD,DEBUG
Now Check AJAX is working Fine.

SEO Tips

Be bold. Use the tags around some of your keywords on each page. Do NOT use them everywhere the keyword appears. Once or twice is plenty.
Deep linking. Make sure you have links coming in to as many pages as possible. What does it tell a search engine when other web sites are linking to different pages on your site? That you obviously have lots of worthwhile content. What does it tell a search engine that all your links are coming in to the home page? That you have a shallow site of little value, or that your links were generated by automation rather than by the value of your site. Here is an example of deep linking, in this case to my personal happiness workbook.
Become a foreigner. Canada and the UK have many directories for websites of companies based in those countries. Can you get a business address in one of those countries?
Newsletters. Offer articles to ezine publishers that archive their ezines. The links stay live often for many years in their archives.
First come, first served. If you must have image links in your navigation bar, include also text links. However, make sure the text links show up first in the source code, because search engine robots will follow the first link they find to any particular page. They won't follow additional links to the same page. You can see this in action at the link to the home page on this web site monitoring page
Multiple domains. If you have several topics that could each support their own website, it might be worth having multiple domains. Why? First, search engines usually list only one page per domain for any given search, and you might warrant two. Second, directories usually accept only home pages, so you can get more directory listings this way. Why not a site dedicated to gumbo pudding pops?
Article exchanges. You've heard of link exchanges, useless as they generally are. Article exchanges are like link exchanges, only much more useful. You publish someone else's article on the history of pudding pops with a link back to their site. They publish your article on the top ten pudding pop flavors in Viet Nam, with a link back to your site. You both have content. You both get high quality links. (More on high quality links in other tips.)
Titles for links. Links can get titles, too. Not only does this help visually impaired surfers know where you are sending them, but some search engines figure this into their relevancy for a page.
Not anchor text. Don't overdo the anchor text. You don't want all your inbound links looking the same, because that looks like automation - something Google frowns upon. Use your URL sometimes, your company name other times, "Gumbo Pudding Pop" occasionally, "Get gumbo pudding pops" as well, "Gumbo-flavored pudding pops" some other times, etc.
Site map. A big site needs a site map, which should be linked to from every page on the site. This will help the search engine robots find every page with just two clicks. A small site needs a site map, too. It's called the navigation bar. See how the second navigation bar at the bottom of Last Minute Florida Villas is like a mini-site map?

SEO Tips

1.If you don’t want too much competition from other SEO’s, choose your keywords precisely. For example, Instead of keyowrd Loan choose keywords like Bank Loan, Equity Loan, Student Loan, Home Loan etc. Order of keyword also matter for search engines. Search engine treats “Loan Equity” and “Equity Loan” as different keywords.
2.Best seo practice is to get at least one of your primary keywords in domain or sub domain name of your website.You can use hyphens (-) to separate multiple keywords.For example: seo-service, seo-guidelines, free-seo each cover two keyords.
3.Get your second or third keywords in your directory name and filename. For example http://www.hiddentricks.com/seo/free-tips.html is best for keyword “free seo tips” , “seo hidden tricks” or "free seo tricks"
4.Keep your webpage free from any syntax error, declare document type at the beginning and validate your HTML and CSS because search engine don’t like pages with too many errors.
5.Give a short Title in of your page in 3-9 words (60-80 characters) maximum in length containing your primary keyword.Remember it will be displayed in search results so choose wisely.
6.Try to include your most important keyword phrases in heading tags on your page if you can but keep in mind it should not be exactly same as title of your page. You can use (H1 H2 H3) tag for specifying anything important. To reduce size of heading use CSS.
7.Specify Meta keywords in heading of document. Limit it to 15 to 20 words. Although not all the search engines give importance but there is no harm doing it. Search engine like Yahoo still give it importance.
8.Write Your Meta Description tag attractive containing keywords because it will appear on the search engine result pages.
9.Use text for navigation menu instead of using images or Java scripts.
10.Try to include your most important keyword in hyperlinked text and text and text that immediately precedes or follows the hyperlink. Do not use same keyword always use synonyms at few places.Jusk like instead of seo, I have use search engine optimization at many places on this page.
11.If you are using images then use “alt” attribute to describe your image with proper keyword.
12.One of the best webmaster guideline is to submit sitemap of your website to make sure all pages of your website are indexed by search engine crawlers.
13.Keep size of your webpages less than 50KB so it is downloaded fast and visitors don’t have to wait for long. For good SEO site page size ideal should be 15KB.
14.Try to avoid your content in Flash, frame, images, java script because crawler find it very difficult and it is against seo tips and guidelines.
15.Don’t use dynamic url because it don’t contain keywords so its not search engine friendly. If you are using any script which shows dynamic pages then make sure at least it should include one keyword.
16.Don’t try to spam and never use methods like cloaking, keyword spamming or doorway pages. Many seo advices to have multiple domain name and link each other but according to our SEO tips and guidelines search engine can penalize you for this.Instead of that try to add more quality content to your existing website.
17.Submit your website only once to google, Yahoo, AltaVista and other search engines and open directory.Don’t use any script or website for automatic submission.
18.If your website contents changes very often then provide visitor with Newsletter and RSS feed.
19.Write articles on website related to yours having higher page ranking and leave your websites link.
20.Get link from other sites related to yours, search engine consider it as vote in your favour.
