i was wondering if i could capture transaction time automatically. e.g. if form has a grid submit button and user clicks submit button to submit changes on a grid to database, is there a way to capture start time when user clicked the button and reply user got back from page?
View 3 RepliesI want to know how much data is recommended to make transaction in web application at a time. I have 30,000 data. I want to insert and update in different transaction.

I have a quiz application in which i am adding from date and to date. If the todate expires then that quiz will not come from the database. Now i want the timer also with the todate.
For example - fromdate is 1/6/2011 and todate is 6/6/2011. I am using DateTime object for these fromdate and todate. In between these dates i have 4 quizes. I want to set times for these four quizes so that they will expire when the timer time is over.
I've got all of my ASP.NET requests wrapped in a Session and a Transaction that gets commited only at the very end of the request. At some point during execution of the request, I would like to insert an object and make it visible to other potential threads - i.e. split the insertion into a new transaction, commit that transaction, and move on. The reason is that the request in question hits an API that then chain hits another one of my pages (near-synchronously) to let me know that it processed, and thus double submits a transaction record, because the original request had not yet finished, and thus not committed the transaction record.
So I've tried wrapping the insertion code with a new SessionScope, TransactionScope(TransactionMode.New), combination of both, flushing everything manually, etc. However, when I call Refresh on the object I'm still getting the old object state. Here's some code sample for what I'm seeing:
Post outsidePost = Post.Find(id); // status of this post is Status.Old
using (TransactionScope transaction = new TransactionScope(TransactionMode.New))
{
Post p = Post.Find(id);
p.Status = Status.New; // new status set here
p.Update();
SessionScope.Current.Flush();
transaction.Flush();
transaction.VoteCommit();
}
outsidePost.Refresh();
// refresh doesn't get the new status, status is still Status.Old

View 1 RepliesHow can i capture Application pool recycle event in asp.net c# code so that when recycle event occurs i can make a post back or refresh the page in the code ?. Our Application sessionstate mode is StateServer which helps me in not loosing the session data but still i need to refresh the page at server side only on this particluar event.The reason is at the client side javascript webform_DoCallBack doesnot fire when there is application pool recycle and thus website stops getting updates.we have a timer set to 15 minutes when webform_DoCallBack fires and fecthes updates for the page and displays it.

View 1 RepliesMy goal is to extend the display time of the tooltip of a web control (say a label) since it disappears too fast (the tooltip is simply flicking and is very hard to read). But it looks like there is no available property that I can set to extend its show time. note that it is web application. And also having a transparent image over the label control and using the image title to mimic as tooltip is not appropriate in this case since there are too many labels (and other controls) that require the tooltips and lots of useless images will dramatically slow down the page display time.

View 3 RepliesI need to add a "real-time" element to my web application. Basically, I need to detect "changes" which are stored in a SQL Server table, and update various parts of the UI when a change has occured. I'm currently doing this by polling. I send an ajax request to the server every 3 seconds asking for any new changes - these are then returned and processed.
It works, but I don't like it - it means that for each browser I'll be issuing these requests frequently, and the server will always be busy processing them. In short, it doesn't scale well. Is there any clever alternative that avoids polling overhead?

View 1 RepliesI 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.
View 1 RepliesI'm working on an application (a web application, asp.net and c#) which is datetime-dependent, so, based on the current date, it will launch forms for the logged user to fill in.
I've been thinking about how we're going to simulate real usage of the application, for debugging and testing purposes.
So I'm talking about replacing all those:
DateTime currentDate = DateTime.Now;
with something like:
DateTime currentDate = MyDateClass.GetCurrentDate();
And then I'll have a class:
public class MyDateClass
{
private DateTime _currentDate;
public DateTime GetCurrentDate()
{
// get the date, which may be different from DateTime.Now
return _currentDate;
}
public void SetCurrentDate(DateTime newCurrentDate)
{
// set the date to the value chosen by the user
_currentDate = newCurrentDate;
}
}
allowing me to set the current data, by invoking the SetCurrentDate method, for example, in the code-behind of a link button and a calendar input.
how should I exactly store the DateTime variable, throughout all the application? I can't work with the session in this class, right? Should I work with the Thread?
