does DbCommand.Dispose() automatially close the database connection?
Here is my code:

string sqlCommand = "procUIBillingAdjustmentsCreditInvoicedSegment";
DbCommand dbCommand = db.GetStoredProcCommand(sqlCommand);
DataSet ds = new DataSet();

I have a page where I load a couple of dropdown lists from the database (DB). I do this by calling a general function that connects to the DB and gets the data to the dropdownlist. This means that I can have three queries to the DB while rendering one page.
should I close and dispose the sqlconnection, sqlcommand and sqldatareader at the end of this function?
Would it be faster if I left it open for the next call, if you get what I mean, or is it best to close and dispose it every time?
There's a problem, wherein a XML Document.Save is resulting in the error the process cannot access the file, because it is being used by another process or the statement an Invalid XML Document.I think it's because I do not dispose the XML Document object after it's operation is complete.Is it possible to do this.Is there a workaround?

View 3 RepliesI have developed a web application which downloads files from FTP server. I want to run this application every day at 09:00 and automatically closed when the job is done.
I tried javascripts "window.close, self.close etc" but couldn't workd.
It is worth mentioning that the website is hosted on Windows Server 2003.
am trying to fix an issue. I have an ASP.NET Ajax's TabContainer on the page. And each tab there is a gridview control that gets binded onload. However for some reason the browser gets closed automatically after the page renders. If I remove the TabContainer then it works fine. I think the binding code will no way effect the browser to close bacause no where in my code I am registering any Script block.Also one notable thing is this happens only in IE 8. It works fine in firefox and other browsers.I don't know if anyone encountered a similar issue before.
View 1 RepliesI recently inherited an asp.net website made up of multiple .aspx and .ascx pages and being rather new to web development and especailly asp.net. I have the site create a cookie upon login to automatically log users back in if the page times out on them while they're entering information.
I need the site to automatically log users out when the site is closed. Obviously using the me.close event on each page won't work because we don't want it to log people out every time they navigate to a new page in the site.
I've tried setting the timeouts in both IIS and in the files of the website to longer but it doesn't seem to have an effect.
Is there an easy way to automatically log users out when they leave the site but not when they navigate from page to page.

Which the best place to close the connection. Is it in Server side or Client side?
Our site was under Slow HTTP POST DOS attack recently. It's when your server receives a lot of incoming connections and keep them for long time because the sender sends information very slow and server cant serve real users' request - denial of service.
So I decied to reject such POST requests:
void Application_BeginRequest(object sender, EventArgs e)
{
if ( _my_condition_here_ )
{
_reject_the_request_by_dropping_connection_
}
}
The problem is that I can't drop the HTTP connection in asp.net:
Response.End(), throw new Exception(), even Thread.CurrentThread.Abort()
don't close the connection. It waits while sender sends all the fake data, then answer to it with '500 server error' or something. The slow POST attack still will be successful in this case.
How can I just drop the connection?

The reason this question came up, is because if I run my website application with a SQL Server data store, and I terminate the browser (terminating the session), I try to open up SSMS to edit the DB. But I can't access the database because I believe there is still an open connection, even after application termination.
Is it recommended to close the database connection upon session/application closing? Or am I way off on what I'm thinking could be the problem?

I can open the modalpopup, can close the popup, but if i click the "edit" button to edit any of rows, the popup closes automatically. If I click again, the "Update" and "Cancel" buttons shows, and after clicking one of those, popup closes again. The above code works, if i use gridview the insert, edit or delete the data, does not close automatically. What may be the cause of this problem.

View 1 RepliesI am having trouble wiht my AJAX collapsible Panel Extender. I have the CPE opening a panel that contains the Table of Contents of a document being displayed on the page. A user clicks on the link for a certain part of the document, the event triggers a C# function that gets the file that particular section is contained in an displays the section. Right now you have to, of course, click on the TitlePanel to open and to close the CPE. What I want to do is have it close automatically whenever a link inside the content panel has been clicked. I have tried placing this.cpeTOC.Collapsed=true; in the functiion that gets the files but it does not work. I have also tried the autocollapse property of the CPE and it just collapses whenever someone moves thier mouse from the titlepanel.
