I am want to develop a quiz site using MVC 2. A single page will display only one question. The examinee will select or type the answer and press Next button to proceed.
My business logic on the server side will record the time elapsed between two consecutive page requests. This time elapsed must not be tempered by any means to make a reliable diagnostic report.
my app requires an elapsed time calculation that I have done like this
CONVERT(Varchar, (DATEPART(dd, GETDATE() - DateAdded)-1) * 24 +
DATEPART(hh,GETDATE() - DateAdded)) + 'h:' + CONVERT(Varchar, DATEPART(mi, GETDATE() - DateAdded)) + 'm' AS ElapsedTime
This works.. I can then colour my grid view cells accordingly using the substring function.. the problem is that I have been told that using GETDATE three times is not a good use of resources, is it possible to use the Datediff function to get the same result?
I have 2 fields being displayed in a Gridview, StartTime, EndTime. I want to create a 'Time" column which shows the elapsed time in HH:MM format. (StartTime - EndTime) This was all generated with VS2008, table is pulled from an SQL Query.

View 5 RepliesIs it possible to measure the elapsed time from when a user clicks an 'ajaxified' button until the ajax controls are updated?
I'm using ASP.Net v4, Visual Studio 2010, C#, and the MS AjaxToolkit.
I am using the System.Timers.Timer class. And I enable when I send a message and disable when I receive the message. How do I calculate how much time has elapsed. I have set the interval as 1 sec
Basically I retransmit data after 1000 sec again if I do not recive an ACK. I retransmit 5 times max until I get a Ack. If I receive and something before 150ms then I stop retrnsmission.
Here's the code:
timer1.interval = 1000;
port.Write(data)
timer1.enabled = true;
event handler for the received data.
timer1.enabled=false;
Let's say I have a Label on my page. In PageLoad() it's Text parameter is set to "This is my first text".
After, for example, 1 minute I want this Label to change it's text parameter to "This is my second text" (completely automatically, without any interaction of a user with this site).
i have simple form which consists of 2 labels and 2 buttons, the first label will display the current time and second label will display the cached time for 2 mins which is absolute..
no w when i click on first button only current time have to get update,, and when i click on second button both current time cached time have to be updated even though the cached time of 2 mins not elapsed also.
We have an ASP.NET web app talking to WCF for data. After resolving a number of service and db level performance issues, we turned to look at the web app itself.
After running a profile while hitting a few common pages, ProcessRequest is at the top of the list as far as elapsed exclusive time (which means time just in that method and any kernel code if I'm not mistaken)
Function Name
Elapsed Inclusive Time
Elapsed Exclusive Time
System.Web.UI.Page.ProcessRequest(class System.Web.HttpContext)
31,573.64
17,915.56
Viewstate sizes are not severe, prob 60k at most for fattest page.

View 18 Replieswe have this web service that sends JSON code to an iPhone application.
Each time the app makes a request, the web serice accesses the database, grabs corresponding xml data, transforms it to JSON code and then sends it back to the app.
the xml data gets updated approximately every minute, you can assimiliate this process with a sport app of which you can watch live game commentaries.
Now the iPhone app is going to implement a refresh button which a user can proactivly hit it against the service to fetch the latest data.
So we need to implement something that is capable of handling multiple requests that could occur at the same time or in a very short period of time.
I run a site with decent traffic (~100,000 page views per day) and sporadically the site has been brought to its knees due to SQL Server timeout errors.When I run SQL Profiler, I see a command getting called hundreds of times a second like this:
exec dbo.TempGetStateItemExclusive3 @id=N'ilooyuja4bnzodienj3idpni4ed2081b',...
We use SQL Server to store ASP.NET session state. The above is the stored procedure called to grab the session state for a given session. It seems to be looping, asking for the same 2 or 3 sessions over and over. I found a promising looking hot fix that seems to address this exact situation, but it doesn't seem to have solved the problem for us. (I'm assuming this hotfix is included in the most recent .NET service pack, because it doesn't look like you can install it directly anymore). I added that registry key manually, but we still see the looping stored procedure calls like above (requesting the same session much more often than every 500ms) I haven't been able to recreate this on a development machine. When two requests are made for the same session ID, it seems to block correctly, and even try to hit SQL until the first page releases the session.
I have a requirement to calculate the Web application idle time. Say the user doesnt use the web application for 15 minutes, then a message needs to be displayed to the user.
