I m developing online examination website.
I want to show remaining time during examination without java script code.
I tried that by adding 10 minuts in starting time of examination and then continuously subtracting current time from that added time.
I m using label to show time . But it gives conversion error.
I am developing a web application which will deal with online examination. The requirement is:
There can be n-number of sections in an exam and admin users should be able to create questions/answers and add to an exam. The questions should be displayed for a certain amount of time in the browser with meclock and it should move to next question automatically. User should not be allowed to open any other instance of the browser or login from another IP if the exam is in progress.
I am seeking community vote of how would someone design the application to meet all these criterias? What patterns should be used? What components to reduce the development time etc..My technology stack is C#, ASP.NET MVC or ASP.NET with SQL Server.
I am a newbie and have designed a website using ASP .Net 2.0 with C# 2005. On the home page I am displaying rates of a few items which gets updated every 15 minutes. The new rates are entered through a different web page into a SQL Table and I am using Page Refresh of the home page to update the rates every 15 minutes. Everything is working ok upto this. But now I have to display a countdown timer of time remaining for the next update on the home page. I am totally clueless as how to approach the problem.

View 1 RepliesI want to create a Online Exam site in ASP.NET .In that i want to display Test based on the Date and time and the user can take the test at the time set my the Teacher.
For Example:
Teacher want to take C Test for the Mid Semester Test and the test is schedule on 1 May 2010,then the test should appear on the test page on the 1st may only and the user should be able to take the test on the set time.
The problem is that if i use System time then user can change the system time and can take the test schedule in future.
So i want to know how can implement this thing.I have given many online test but dont know how they work out the time and date logic.
I would like to pop up a box that warns the user of session timing out in 5 minutes. There are lots of examples of this on the net and I can figure something out. My question however is how to get the time remaining.All examples I read about set a client side timer to countdown from last postback. I would like to do something different. I would like to make an AJAX call to the server and get the time remaining from the server. Is this possible?Since an AJAX call will not reset the session timeout timer can I read the number and send it back to the client?
View 1 RepliesI have an object on the webpage that I normally will attach a source to. When doing that as in the code below it works fine.But if I have a empty string for setSrc1, then the webpage shows a message in the left down corner that:
"1 items remaining" Waiting for...
How would it be possible to not have this message if no src is set to the Object1 ?

I'm making a forum.
I need to show if a user is Offline or Online.
Like this:
Where is says Online i need it to say Offline when the user if offline.
Okay, now i think i got explained what i would like to do.
How i would like this to work:
When a user logs in i want his status to change to Online.When the user press Log Out i want the status to go Offline.
When the user haven't been active for 10 minutes i want the status to change to Offline, but he is still logged in.If he clicks on something he's active again, so i want the status to go to Online again.If the user browse away from the site or close the browser/site i want it to go to Offline status again.
I'm using a global.asax and i would like to know how to show a list of users on-line and maybe who has been on-line too .
I know how to show a number of users on-line now i would like to show they names too.

View 1 RepliesI'm developing an online auction with time limit.
The ending time period is only for one opened auction.
After logging into the site I show the time left for the open auction. The time is calculated in this way:
EndDateTime = Date and Time of end of auction;
DateTime.Now() = current Date and Time [code]....
The problem is that when I login from different browsers at the same time the browsers show a different count down.
what I need to know is how to show a count of how many users are signed on with a custom sql script, here is what i got that shows total users but not total online
[Code]....
Again this gives a total count but i need a total count of who is online with this setting, and try to keep it in sql statement if possible as i have not yet learned how to use stored procedures.
I have a client request that all times be displayed in Pacific Time Zone, regardless of client settings. I'd like to avoid a scenario where I have to call a function for every time display and instead have a single point where I can make the switch.
I'm thinking a custom culture might do the trick, but I wanted to ask before I set off down a potentially blind alley (or miss something trivially easy).
I have an ASP.NET website that worked fine using and debugging in VS2008. I went through the upgrade process opening the solution in VS2010. I can run the site, but as I make changes in the app_code folder classes, they don't seem to commpile and warn me of compile-time errors. As soon as I get to a point that calls the class, the errors show up. Sounds JIT I guess, but this isn't how it was working in 08. Is there an option that was changed in the upgrade process? This is a large project, I really don't want to break something and not find out until some obscure page is opened.

I am sure this is not enough.. am I right? so what else I should include there?
