How To Store A Value Into A Session Variable And Load From That Value Back From The Session Variable
Nov 22, 2010Currently in an .aspx file, I am storing a value (filename that was created in that session) in an hidden text box. When the user clicks on the "Print" labeled Hyperlink control, it opens the file that was stored in the hidden text box control. But when the user goes to different screen (in the same session), I loose the filename value that is stored in the hidden text box control. So I would like to store the filename variable in a session variable. So that if the user leaves this .aspx file and comes back to this .aspx file I can load the value into the hidden text box from the session variable.

State Management :: Public Variable Vs Session Variable To Store Logged In UserID
May 17, 2010I have a web application which uses a session variable to store the logged in userid. If no user is logged in, of course this variable will be empty and the contents displayed on my website are meant for guests. If there is a user logged in, the user specific controls/access/links will then be a displayed.
I am now having issues with my hosting where on shared application pool, the worker recycle is triggered every 90 minutes, this will clear sessions causing all my users to be logged out. I opted for a dedicated application pool, which got worse because I am only allocated 50MB memory limit and if this is reached, the worker recycle is triggered and I lose my sessions again. I have tried as much as possible optimization techniques, e.g. dispose where possible, close connections, disable viewstate for static controls etc but my memory per instance keeps building up from page to page without any signs of improvement. I don't use loops nor store huge objects like bitmaps etc but my sessions are now gone even faster than 90 minutes in shared application pool before.
I have considered using SQL Session State but there isn't a simple guide on using this with MySQL. I am getting desperate and considering using a public variable, a string as a replacement to store logged in user id instead of in a session variable. I am pretty sure this will solve my issue with sessions being recycled but are there any negative consequences of doing this? One problem I can think of is if the user closes the browser, the system will never know that the user is now logged out and this public variable should be nothing. In this scenario, will the GC eventually clear this abandoned public variable.

my quesation is session is better or Globel variable is better way use in my situavation..
State Management :: Global.asax To Load Up Several Session Variable When A Session Starts?
Sep 14, 2010I added the following code to global.asax to load up several session variable when a session starts. I'm assuming that when a page goes to use the variable that I should be
1) checking at the page level that the value is valid not 0 when its not expected to be 0, not a zero-length string when its expected to have a length
2) have code at the page level that sets the values if the values have not been set as when the Session timeout, ideally putting the code in a class derived from Page and then deriving all of my pages from the new class so that the code does not have to be repeated in every page

State Management :: Session Variables And Tabs / Is There A Way To Reset The Session Variable

State Management :: Session Variable Persisting Even After Abandoning A Session - Closing Browser Windows
Aug 5, 2010I 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.

Web Forms :: Session Variable In VS2010 - Error "Session Is Not Declared"

View 9 RepliesWeb Forms :: Populating Dropdownlist From Session Variable?
Nov 3, 2010To speed things up for the visitor of my web page, I put a personalised dropdownlist in a session variable (as below).
The idea is that if the user is logged in and the ddl session variable is Nothing then it should be set here, and the next times the dropdownlist should be set from this session variable.
The session seems to be populated ok, but the resulting dropdownlist (ddlMenu) doesn't (it just becomes blank). I suspect that it has soemething to do with the way I try to assign it. No matter what I try I run into problems, saying that one thing is a one-dimensional array and the other thing a listitemcollection, or the like. What should I write in the last line?
If Session("aid") IsNot Nothing And Session("ddl") Is Nothing Then
Dim ddlny As New DropDownList
ddlny.Items.Add(New ListItem(vstr, ""))
ddlny.Items.Add(New ListItem(kontrstr, "PageA.aspx"))
ddlny.Items.Add(New ListItem(bstr, "PageB.aspx"))
If dt IsNot Nothing Then 'dt is a datatable, populated elsewhere
For i As Integer = 0 To dt.Rows.Count - 1
ddlny.Items.Add(New ListItem(dt.Rows(i).Item("name"), dt.Rows(i).Item("did")))
Next
End If
Session("ddl") = ddlny
End If
ddlMenu.Items.Clear()
ddlMenu = Session("ddl") 'THIS IS THE LINE THAT SHOULD BE REWRITTEN.

Web Forms :: Using A Session Variable As Web Form Validator Control
Apr 13, 2010I'm creating a session variable in my .vb file and I'm able to display it in my .aspx but I can't seem to use it as a control in my asp:CompareValidator. The only way I can think to reference it on the .aspx page is with <%=Session("MyVariable") %> but
such constructs are not allowed in a validator with runat="server". But it seems like the validator must have that attribute and value.
Really what I'm trying to do is validate a user-entered number in a textbox against the one populated in that same textbox from the database. If the user replaces the textbox value with a smaller one I want to show an error message and prevent submit.
