I have two datetime2(1) fields in my db. I will calculate the time in hours and minutes between them. That I have done this way:
[Code]....
This works. But how can I calculate the avgerage speed if I have drived 665 kilometers in this time? I know how to do it with only houurs but not with the minutes to. I have tried this and I think it works. Is it correct?

There are various website speed test online tools available. Few of them are listed on: [URL] I tested my website using iweb and selfseo. My website is showing 0.03KB Average speed per KB everywhere. Even google also is giving same kind of results.I tested the site using Page Speed and YSlow. I have already followed most of the recommendations suggested by these tools like efficient use CSS, contents across the domains, caching, compression and all. But still I am getting the same average speed per kb. Page speed is showing around 85/100 as my page speed score, so I guess I have optimized my site a lot. My questions here are:
1. What are the other factors affecting the avg speed per kb of a website?
2. How to improve the Avg speed per kb?
3. Is there anything related with the Server Software and Hardware that I have to check?
Note: I tested by uploading a plain html page with simple text "Hello World", but the avg speed per kb is the same for this page as well. Same is the case with the rest of the pages.

I was reading this article about relative time calculationThe problem is that the results are wrong due to the time offset. My webpage is Greek.So how should i modify that function to work correctly, including the GMT+2 or GMT+3 hours offset?

I have events that have start and end dates and I want to display the current week that the event is in progress. To currently do this I am finding the week of the end date and subtracting the week of getdate(). This works unless the event goes into the next year and then it returns 0 .Here is my sql
course_status_1 = CASE
WHEN
GETDATE()[code].....
What I need to happen is for an event with start date and end date in differnet years to calculate what week of the event get date is currenty in.
I have a web application running on ASP.NET 3.5 which basically stores, retrieves, and allows users to manipulate data from a SQL Server 2005 database. One of the features allows users to search through the records in the database. When the system was first launched last year, there were no records, so searches were lightning fast. However, over the past year, about 100,000 records have been entered, so most searches now take over 15 seconds to perform. I'd like to speed up searches, but there are problems with both of the conventional approaches I can think of:
Caching - The database does all the heavy lifting in this application - the ASP.NET web application is little more than a UI that passes user input to the correct stored procedure, and displays the returned output. The stored procedures are responsible for interpreting user input, applying the business rules, and transforming the underlying tables and views into a context-sensitive result set which the application just displays as is. Unless if there's a way to apply a stored procedure to a C# object/collection (the cached records), and get another C# object/collection back, effectively bypassing the database, I don't think this will work.Stored procedure optimization - There's some optimization potential here, but even a simple SELECT * FROM TheView statement on the underlying view currently takes 11 seconds according to SSMS, and I expect that the amount of time taken will continue to increase as more records are entered.Are there are techniques out there that I'm not aware of, which could be used to bring searching down to a reasonable amount of time (5 seconds or less per search)?
My web server and database server are currently both in the same room. However, the web server might be changed to a different server in another building about a mile down the street. I want to make sure this doesn't have a negative impact on the connection speed between the database and web server. Is there a way to test the connection speed from both web servers to the database?

View 2 RepliesLast night I did a load test on a site. I found that one of my shared caches is a bottleneck. I'm using a ReaderWriterLockSlim to control the updates of the data. Unfortunately at one point there are ~200 requests trying to update the data at approximately the same time. This also coincided with CPU usage spikes.
The data being updated is in the ASP.NET Cache. What I'd like to do is if the CPU usage is around 75%, I'd like to just skip the cache and hit the database on another machine.
My problem is that I don't know how expensive it is to create a new performance counter to check the cpu usage. Also, if I would probably like the average cpu usage over the last 2 or 3 seconds. However, I can't sit there and calculate the cpu time as that would take longer than it's taking to update the cache currently.
Is there an easy way to get the average CPU usage? Are there any drawbacks to this?
I'm also considering totaling the wait count for the lock and then at a certain threshold switch over to the database. The concern I had with this approach would be that changing hardware might allow more locks with less of a strain on the system. And also finding the right balance for the threshold would be cumbersome and it doesn't take into account any other load on the machine. But it's a simple approach, and simple is 99% of the time better.

View 1 RepliesI have a datetime column in my table. It has a value like this for example: 4/27/2010 7:34:00 PM. I would like to display the time part of the column in military time. So this datetime column would appear as: 4/27/2010 19:34
Is this possible?
I have a gridview, I am binding the gridview with a datatable and in the gridView, my autogenerateColumn is set to true since I am generating the columns dynamically coming from database. I am also doing doing showFooter =true. There are values in the rows of these dynamically generated columns. I need to calculate the average of each of these columns and display it in the footer. so for e.g, I have
A B C
10 11 12
13 14 15
16 12 11
-- -- --
13 12.3 12.6
I have a table that includes a state column and a price column.
I am able to obtain the average price from a particular state using:
SELECT avg(Price)
FROM MainTable
WHERE StateId=x
I would like to display the average price from each state. The only way I know of doing this is 50 seperate datasource controls. Is there another way?
I am simply trying to determine age from a selection of Month, Day and Year representing birthdate, which I have captured from three drop down list boxes, by subtracting the studnetBirthDate from Today. How can I get Age? Using a calendar to select birth date seemed too clumsy because of the year navigation, age ranges from 3 to 26 yrs old. If anyone has a better idea I would be open to that as well. Instead I am using three dropdown boxes, one each for day, month and year.
Dim studentBirthDate
As
Date
Dim stMonth
As
String.........
I am having some issues with the performance. I am binding a Gridview with around 200 records and it is taking a long time. At one time I only display 10 records on the page, but I bind all the 200 records.
Generally what is the number of records that should be bound to a gridview ?
I want to calculate average time to cover a duration of a route.
A route can have multiple trip between different time slots.
trip have TripStartTime and TripEndTime.
For more clear of the Qns for Qns please go to this URL and for table structure please go to this Url.
Trip Time = TripEndTime - TripStartTime from columnin the table.
I have to calculate Actual trips time for different time slots group by Fleet Id which is related to route no in another table..
