re: Handling ASP.NET Session Variables Efficiently

hai Raj...

I have successfully implemented your session state management technique in my project.But I have a doubt

If a large number of requests occurs simultaneously to access a session variable which is managed with the static property ,how it will be handled?? will it be resulted in a performance degradation???

re: T-SQL Query to Find the Second Highest Column Value in a Table

Vinod Dhall — Tue, 07 Oct 2008 06:03:05 GMT

There is one more simple solution to get the Nth highest value :

I have the following value in a table depts column id.

----------

222

233

365

450

556

809

996

1000

1252

Now to get the 2nd highest value i can use

select id from depts t1 where 1

= ( select count(distinct t2.id) from depts t2 where t2.id > t1.id)

And so on to get the 3rd, 4th ... nth value.

Here 0 represent the first value.

re: Blackle - Energy Saving Search

Considering that blackle works only on CRT it might be a waste when it comes to our new tech of Plasmas and LCD’s using liquid display…. But Energy is only 1 part of the concern, there is also the myth of the internet bandwidth being limited.

( news.cnet.com/2100-1034_3-6237715.html ) and various articles covered in the past few months have all been focused around how Ineternet usage and bandwidth would be 50 times more than today and the content created then would jam the internet space.

Typically utilization of bandwidth and usage is directly proportional to the no.,quality & results of QUERIES that a user inputs from the moment he logs on. These queries can be as simple as searching, or as intense as uploading. At the end of it, its all about minimizing the no. of queries.

We are trying to research the potential ways of minimizing these queries by pre-defining most searched “keywords” & “categories”.

By not entering any search query, or typing for searches you would be skipping multiple steps and help in saving energy and bandwidth.

If we all try and add to this pre-defined list of searches, we can help save far more energy, bandwidth and money.

Help us all move towards the green technology.

In your project, find the .dll file from the reference list and in the properties window set 'Copy Local' to true. This copies the DLL to your application directory so it can run.

Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration>\<system.web>\<httpModules> section in the application configuration.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
