I am working on an application that is for online examination,
I need to maintain exam info such that if unexpected closing of browser such as power failure etc, the exam will restart for the user from same last position.
I tried to do it through session state mode sqlserver but problem is what if after closing system without clearing session if some another user want to give exam from same machine?
I am facing an issue in my application when a user directly clicked on browser close [X] button. Browser can be IE, Chrome, Mozilla, Firefox and many more.
What I want to do:
1. as soon as user hits [X] button of browser, need to set their status as logged off in database for which we have a method in Login.aspx file which is within the master page.
2. We do not have any Logoff feature in the application
I am using asp.net 2.0 with c#.
i want a pop up to be displayed when user tries to close the browser and if user click on "no" [i.e. he don't want browser to be closed] then it prevent browser to get closed.
I want to Change application variable value on closing browser, Problem is; I am using sessionState mode="StateServer" and in this mode, Session_end event does not fire in global.asax
how i can detect session_end or browser close and then change the application variable?
on closing the browser the command must execute...
update tablename set islogin='0'..
it is working properly on click of sign out
but
when the user close the browser ,it doesn't updated ....
How to keep the session variables even after closing the browser?
Everytime I close the browser, I lose all the session variables.
Is there any way to keep them?
I want to show a popup about browser compatibility to the users visiting my website. I have used the popup in about 5 pages and it would be annoying for the users to see the same popup for more than once when they visit my website. So I am thinking to use a session and kill it when the user closes the poup. IT should not be shown until the browser is restarted.

View 2 RepliesI have the following main query:
[Code]....
One of the navigation properties of the User object is Users_UserStatus1. This is a one to many (we store the status for each user account, when an account's status is changed, a new record is inserted into the status table as opposed to updating it). One of the search criteria I'm trying to filter on is the UserStatus. So, I pass in a comma-delimited string like so:
[Code]....
The problem, it seems, is that this is only bringing back one record, even though more of them should be matching. Also, I only want this to filter based on the last status for each user, not all of them. Can't quite seem to figure this one out.
I have been spending a better part of a week trying to track down why I am not able to clear all session variables in a web app (vs 2010, vb.net). What I have tracked it down to is that when I remove or abandon sessions that my html pages or codebehind access, it works, but for some reason in any of my class files where I use "Public Shared strConnection as String = HttpContext.Current.Session("strConnection").ToString" to access a session variable, it finds the old one and not the current one. I have to wait for it to time out, go in again, and it will find the new one.
I do not use Linq, and there is only one place in the whole web app that I place the connection string in a variable whcih is when a person logs in. It points them to the correct database. The sqlconnection is set for all of my listviews in Page_Init to make sure that they aren't using any session variable that they create on their own. Interestingly enough that if I use debug to go in each time, exit debug, enter debug again trying to access a different database, it works correct each time. I assume that debug is correctly killing the session variable for the classes for me.
My ASP.NET application will have to handle HTTP GET requests that will have the following URL format: [URL] currently the requirement is to validate that there're no parameters in the query string except id and indicate an error like "unknown parameter P passed". Is such requirement a good idea? Will it interfere with some obviously valid cases of using the application I haven't thought of?

I am transfering data from DB server to second DB server using one test page.
But i am getting following unexpected message ....
The CLR has been unable to transition from COM context 0x205480 to COM context 0x2055f0 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.

We are creating a new user control using a boiler plate template for our application. We noticed that anytime a textbox on the new user control has a focus and the enter key is pressed, the form executes a postback. This happens even if the AutoPostback on the text box is set to true. No other user controls in our app behave this way. What could be some of the places for me too look?

View 2 RepliesI drafted 2 ASP.NET applications using LINQ. One connects to MS SQL Server, another to some proprietary memory structure. Both applications work with tables of 3 int fields, having 500 000 records (the memory structure is identical to SQL Server table). The controls used are regular: GridView and ObjectDataSource.
In the applications I calculate the average time needed for each paging click processing.
LINQ + MS SQL application demands 0.1 sec per page change.
LINQ + Memory Structure demands 0.8 sec per page change.
This Is shocking result. Why the application handling data in memory works 8 times slower than the application using hard drive? Can anybody tell me why that happens?
In the MSDN is writen about TreeNode that:
"By default, a node is in selection mode."
"To put a node into selection mode, set the node's NavigateUrl property to an empty string."
"When a node is in selection mode, use the SelectAction property to specify which event or events are raised when a node is selected."
"Setting TreeNodeSelectAction value TreeNodeSelectAction.Select Raises the SelectedNodeChanged event when a node is selected."
Here is the problem and possibly a bug in the control:
When I set the TreeNode object PopulateOnDemand value to true and call the Collapse() function on that node.Then the TreeNodeExpanded event is raised in addition to the SelectedNodeChanged event.This is in complate contradiction to what is writen in the MSDN.According to the MSDN this sould happen only if TreeNodeSelectAction Property is set to TreeNodeSelectAction.SelectExpand value.
Here is the code:
<asp:TreeView ID="TreeView1" runat="server" AutoGenerateDataBindings="False"
onselectednodechanged="TreeView1_SelectedNodeChanged"
ontreenodepopulate="TreeView1_TreeNodePopulate"> [code]...
Getting an unexpected event firing dropdownlist's selectedIndex event. When I try to redirect from another page by a linkButton. I just changing dropdownlist selectedIndex.Its okay.But after that When I attempt to redirect to another page,DropDownList's selectedIndex event firing (before linkButton Onclick event).But I am not changing any thing in dropdownlist.Somehow its event firing.
also any page viewstates is default (not off).But loading webcontrols into masterpage Page_Load like this :
[Code]....
if this dropdownlist selectedIndexchanged event firing. Because of I am loading webcontrols each masterpage's PageLoadEvent.
What do you prefer this may the reason of this unexpected event firing ? if so. Do you have a better technic to load controls Just for one time and not each pageLoad.maaybe a caching technic I am missing or shoult I use substution.
I couldnt find the main reason why a dropdownlist selectedIndexchanged event firing without I changed anything on that dropdownlist.
what reasons may cause this problem ? if you say viewstate its turned on defaultly. any other reason you know why ?
