Managing Session Timeout In Aspstate Database?
Jun 1, 2009
I am using sql server ASPSTate database for storing session. For testing purpose, I want to set the timeout period of 1 min.
In web.config, I have mentioned sessionState mode = "sqlserver" and timeout = "1"
In Global.asax, in Session_End event, I have redirected to error page.
But Session_End is not firing and hence page is not redirected.
As per my knowledge, The Session_End event is raised only when the sessionstate mode is set to InProc in the Web.config file. If session mode is set to StateServer or SQLServer, the event is not raised.
How can I test session timeout when session mode is set to SQLServer?
Is there any Table/column in ASPState database, where I can change session timeout value ?
I used: Update ASPStateTempSessions set Timeout=1
But still, I cant see session is ending.
How can I test my Session Timeout is working fine or not ?

I have written a page with an iFrame that basically cycles through a series of internal pages on our server displaying daily activity for our company. The problem I think is that it sporadically loses its session and redirects back to the login screen to keep losing its session which is the default behavior for anyone on our site trying to access a webpage without being logged in.
I have set the session timeout to 4hrs, the iframe cycles through 6 pages anywhere from 10 seconds to 5 minutes on each, and I have even set the META refresh on the page to refresh every 3 hours. I don't understand what else could possibly stop this page from staying active.

what would be the best way to manage a connection to a database in asp.net.My application is built using an N-Tier architecture.The DAL consists of static classes with methods such as
Public Shared Sub Delete( _
ByVal connection As MyConnectionClass, _
ByVal contact_id As Integer, _
ByVal contact_timestamp As Date _
[code]....
The point to note here, is that I pass the connection to the DAL from the BLL.Should I create the connections in the MasterPage, store it in an object, then pass it to my business objects as I create them (the thing I'm trying to avoid)Should I create a connection using a static class and calling a method like CreateConnection on it, from the constructor of my business objects (Something I'd like, but I don't want to have a connection per object, I'd like it to be shared for all instances of my objects, but since asp.net is multi-threaded, a static class doesn't make sense to store connections) the solution should also work well in a Windows Forms environment (So no connection storing in session, and retrieving it with a static method in a class, for the current context)?

I am having some problems in my app for the database timeout. Due to some network glitches the query takes more than 45 sec to return the resultset which has about 10,000 rows. Most of the time its fast upto 11-12 secs. My app is runs as a scheduled job in the background.The problem is I need to try three times if i get the timeout exception before writing the error to the error log or exiting. I know i can set the command timeout property to 60 seconds but still i want to try three times before exiting. I have written a method for that but I think there is some flaw in my method. For now i specifically set the timeout to be 5 seconds as i know well that it takes more than 25 seconds for this stored proc to run. I just want to get that timeout expired exception and write ways to handle it.
My problem is if after 2 times I set the connection timeout to 50 so my method goes and get the correct list but it again goes inside the methodname which i have called inside the catch statement and finally returns nothing. It looks like its getting into recursion or something but i am confused as to where i am wrong.[code]

I am storing a session variable that a user types into a textbox. With their valid input, their session gets created and they get a little more functionality than the regular end users of the site.I was wondering if it is possible to find a way to add someone's session variable to the end of a URL. This way we can email a link to one of our clients, they click it, and their session has automatically begun. They already have the textbox to enter their code into, but I was told that it would be much easier for the users to just click a link that will start their session.

I am using VS2008 and SQLite. I have created a database and several tables and am attempting to populate the tables with data from arrays.
The following code (example) works fine but stops after it inserts 30 to 50 records. I am running the VB code in debug mode and when it stops, I press pause to see where it is. It stops on "SQLcommand.ExecuteNonQuery()" and when I press continue (F5) it will insert another 30 to 50 records.
I do not get an error message. Is this a timeout issue? How do I keep the loop running to the end of the array?
Following is example code.
Dim
SQLconnect As New SQLite.SQLiteConnection()
Dim SQLcommand As SQLiteCommand

I have a class that seems to be recursively adding an EventHandler to an event. I have looked at the code but there is no AddHandler on it and there's only one method with the Handles clause.In the memory profiler it shows that the event handler is calling the event handler that is calling the event handler and so on for a rather large number of steps.

Whats the best way to organize code responsible for Form's content.In my case, there is a DataGridView and list, next to it, with a few options available (projects, managers, employees, etc...). Choosing any list's element fills DataGrid with proper data from database.Now, GridFill functions + handling of all add/delete/edit buttons of each list element gives quite a code in the Form's source, which bothers me a bit. How to split it then to avoid problems in the future? While googling, I've seen some advices to use partial classes, modules or just classes. Moving all functions relating the Projects, Managers, ... , to own separate class sounds like a nice idea but then comes the question how to pass all necessary data to the class functions.

have been writing code to replace an old Fortran program. The Fortran program had very organized subroutines which could be called from anywhere in the project. Most of these were relatively small and left a small, easily followed main routine. I'm converting over to VB.net and when I write the subroutines they are all on the same form. Wading through 50-100 subroutines on one form is going to be messy.

An application I am developing creates a directory and text file within the directory. A button is then coded to add a text string to text file. An error is issued stating the file cannot be written to as the is open to another process. This suggests the file needs to be closed before it can be written to.

However, when minimisingmaximising the "Loading" form appears before the parent making it look a little unprofessional. Anything I can do about that (Delay it appearing or attaching it in a different way)?
