I wonder some times how statemanagement efficiently helps a developer to handle the user sessions. Session state management is one which should be handled with care, Other wise it can create various problems. We have to identify how are these sessions

Need Help with Website Sessions Expiring or a Time out.


I work for Motorcycle Market, a company that sells Motorcycle Parts and Motorcycle Accessories. We are on IIS 7 and SQL Server 2008.  The problem is after a certain period of time or if an IIS reset takes place, the very first time the website is opened from any url besides the homepage url [ Motorcycle Accessories ], the website gets redirected to the homepage.  Here are some examples to explain further:

An IIS Reset is done.  If you click on Motorcycle Parts in this post or you copy and past any url into IE or Mozilla, http://www.motorcyclemarket.com/harley-davidson-0-d3.aspx, the website gets redirected to the home page.  Then if you enter this or any url back directly into the browser, http://www.motorcyclemarket.com/harley-davidson-0-d3.aspx, it takes you to the correct page.

After a certain time period, if no users are searching the website, and I am not sure what this time period is, it happens randomply throughout the day, you click on any link,

Round off time to the nearest minute

How would you round this up to the nearest minute? There isn't a built in function to do this so you have to use a little bit of maths to get there. There are 60 seconds in a minute. We already have 38 seconds on the clock. So we need to add on 60 - 38 = 22 more seconds.

Performance Tests: Precise Run Time Measurements with System.Diagnostics.Stopwatch

Everybody who does performance optimization stumbles sooner or later over the Stopwatch class in the System.Diagnostics namespace. And everybody has noticed that the measurements of the same function on the same computer can differ 25% -30% in run time. This article shows how single threaded test programs must be designed to get an accuracy of 0.1% - 0.2% out of the Stopwatch class. With this accuracy, algorithms can be tested and compared.

Date and Time Functions in SQLSERVER

Date and time functions allow you to manipulate columns and variables with DATETIME and SMALLDATETIME data types.

2 DATENAME Function
3 DAY, MONTH, and YEAR Functions
5 DATEADD Functions
6 DATEDIFF Function
7 More SQL Server Functions

Data Types - Date and Time in SqlServer

Date and time values can be stored with either the DATETIME or SMALLDATETIME data type. The difference between the two is that SMALLDATETIME supports a smaller range of dates and does not give the same level of precision when accounting for time. The DATETIME data type can hold values from January 1st of 1753 to December 31st of 9999. The time is stored to the 1 three hundredths of a second and each value takes up 8 bytes of storage. The SMALLDATETIME data type can hold values between January 1st 1900 and June 6th of 2079. The time is tracked to the minute and each value takes up 4 bytes of storage. The majority of business applications can live happily with SMALLDATETIME, however, if you are in an environment where each second matters or you need to make estimates to the distant future (or past) then you have to resort to DATETIME. If you fail to specify the time when inserting a value into a DATETIME or SMALLDATETIME column, a default of midnight is used. If you fail to specify the date portion the default of January 1, 1900 is used.

How to programmatically add controls to Windows forms at run time by using Visual C#

Create a Windows Forms Application
Start Visual Studio .NET or Visual Studio 2005 or a later version, and create a new Visual C# Windows Application project named WinControls. Form1 is added to the project by default.
Double-click Form1 to create and view the Form1_Load event procedure.
Add private instance variables to the Form1 class to work with common Windows controls. The Form1 class starts as follows:

.NET 4 Web Application Startup Time

I was chatting with Jonathan Hawkins and some of the folks on the ASP.NET team about performance and Jonathan mentioned the startup time for large ASP.NET applications is improved on .NET 4. There are some improvements in the CLR and in ASP.NET itself that helped. If you have a giant app, you should do some tests.

Built-in Functions - Date and Time Functions

Date and time functions allow you to manipulate columns and variables with DATETIME and SMALLDATETIME data types.

Essential SQL Server Date, Time and DateTime Functions

The essential date and time functions that every SQL Server database should have to ensure that you can easily manipulate dates and times without the need for any formatting considerations at all.

Date/Time Conversions Using SQL Server

There are many instances when dates and times don't show up at your doorstep in the format you'd like it to be, nor does the output of a query fit the needs of the people viewing it. One option is to format the data in the application itself. Another option is to use the built-in functions SQL Server provides to format the date string for you.

Information about sessions


Some questions about sessions:

I know sessions information is stored in the form of cookie and you can use qurystring for that if you set cookieless session in web.config. But I don't exactly understand the scope of a session.

What I believe is when you login to a website, a session cookie is created and the scope of that session is within that page only. If you close the browser that session gets killed and when you open the browser again and go to that site then a new session is created ie a new session is created on every request. Is this correct?

But I have seen in many websites, even if you close the browser and open it again the session is not killed, how does that happen?

Can anyone clear out and explain the scope/lifetime of sessions


huge number of data from database ... so how to minimize load time


Hi ...

I have used the above method to configure my crystal report ...

Its working fine , But i have huge number of data in database ....

So , it take long time to load the report ...

So , i have decided to show only the last 50 records inserted into the database , not all the 500 records to be loaded every time.

Plz help me with this issue  ...


Also , Plz explain me abt index legend in crystal report.

Can this code be setup to run against the whole database instead of just 1 record at a time?


We have made some changes to this code to start capturing 1 new field of data and updating it as new records are added. But there is currently about 120,000 records more or less.. those records of course dont have the new field populated with anything..

We would like to run this logic that already in place and run it against the tables to update the fields 1 time. I think to make it easier, if it can be setup to expect the "valueTwo" variable, so that we can run it againt the individual codes instead of doing all the records at one time.. there are codes that only have a few records, so it would be best to test initially against the small code group.


            strSqual = "insert into trans (trans_type_name, trans_date,sys_id,mod_user_id,show_ind, remoteCode, techName) values('" & valueTwo & "','" & TransDate & "',"&strSystemID&", 1,'T', '" & dbQuote(strUser) & "', '" & strTechName & "')"        
            'get the new transaction_id out for just inserted alarm   
            strSqual = "select max(transaction_id) as transaction_id from trans"  
            set rst = getStaticRecordSet(strSqual)
