Hi,
I am having a web application, which can be accessed by different users based on their userid's and passwords.
Now I want to prevent user 1 from accessing the application from more than one system.
In order to prevent this I have created a table with three columns as :
userid password flag
with flag having two values (true, false)
true means that user is logged in
false means looged off
session id generated by the server when the session is created
SESSION.SESSIONID gets the id generated on the IIS.
reference: http://msdn.microsoft.com/en-us/library/ms524326.aspx
now how can I delete it?
so that there can be only one user per user id.
am I right in achieving the goal?
I don't want to use Asp.net MembershipProvider.
thanks

I don't think I understand what you are trying to accomplish. Are you looking to limit the IP addresses that can access the application? Are you trying to ensure that if a person is logged in through one browser that they can't be logged in from a second?

Why you want to delete it ? How does it relates with signle user singing? Session ID is unique for each and every user.
On Logoff you make sure that, data base field is reseting properly. and what about if user Close the Browser by Clicking [X] button ? You need to handel this situation also.
Thanks !

You can try this way,
function CheckBrowserClose()
{
if(window.event.clientX < 0 && window.event.clientY <0)
{
}
}
And called it on Body unload.

|
|
|
|
it is possible when the window is closed or at the time of session time out, but it is not possible in case of network failuer

Hi Abhijit and YESU,

I think Yesu's point is correct , can we handle this scenario as well, it does exists in gmail though.
whenever two or more users with same email id's log in, in different machines , one of them can log out all other machines.
thanks

Try with ajaxResponse.firstChild to get the first child of ajaxResponse node.

Are you dynamically adding the control in the Load event of the page?
If so, try adding it in the Initevent instead.

Hello,
I'm building a site with asp.net (fw 3.5).
In my code behind I'm filling a literal with a "mailto" link which have a subject and a body parameters in hebrew.
When I run the site and click the link it open my outlook but the subject and body are in gibberish (scrambeled latters).
I tried saving the page as hebrew or UTF. Also tried adding meta of hebrew or UTF-8. nothing worked 
Any ideas way is that or what I can do?
Thanks.

Actually it is totally related on how the data is sent to the Outlook from the browser. The process is invoked from the Browser and depends on the browser itself.
Rather than doing this, I think the better way would be to send email from your web interface, not using mailto in your case.
