i want to create a global session which will stay active until and unless we manually kill it.how to do this in asp.net with c# what i am doing is
HttpContext.Current.Session["UserID"] = someValue;
but in this way the session is lost after some time.
I wrote a page using a tabcontainer to display different functionality. On the main page I have a modal popup used for login. In ie8 everything works fine, but in IE7 the modal popup is hidden behind the tabcontainer and the controls on the tab stay active.
View 2 Repliesi have a menu bar in my master page that is made up of 4 hyperlinks with background images that are being set using css. on hover-over, these images are swapped out, also by css. so each menu item (hyperlink) has two images, a static image and a hover-over image. when a user clicks one of the menu items and is taken to that page, i would like that hover-over image to "stick" for that page. here's my code:
<div id="nav">
<asp:HyperLink ID="hlHome" runat="server"
NavigateUrl="~/Default.aspx" CssClass="menuHome" />
</div>
#nav a, #nav a:visited
{
height:39px;
border:none;
padding:0;
display:block;
cursor:pointer;
}
a.menuHome, a.menuHome:visited
{
width:76px;
height:39px;
background:url('home.gif');
}
a.menuHome:hover, a.menuHome:active
{
width:76px;
height:39px;
background:url('home_hover.gif') no-repeat;
}
my hyperlinks background images are rendering, the mouse-over effect works too, i just can't get the mouse-over image to "stick"/stay active.
I 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

I am developing an intranet application that needs to authenticate against a global catalog server (containing about 14 domains). What would I use for the connection string?
GC://DC=mb,DC=rellish,DC=com
Whenever an unhandled exception occurs on our site, I want to:
Send a notification email Clear the user's session Send the user to a error page ("Sorry, a problem occurred...")
The first and last I've had working for a long time but the second is causing me some issues. My Global.asax.vb includes:
[Code]....
When I run a debug, I can see the session being cleared, but then on the next page the session is back again!
I eventually found a reference that suggests that changes to session will not be saved unless Server.ClearError is called. Unfortunately, if I add this (just below the line that sets "ex") then the CustomErrors redirect doesn't seem to kick in and I'm left with a blank page?
Quick question: Is there a "per-user" data storage object (similar to Session) that I can store data in the global scope (similar to HttpRuntime.Cache)? Almost as if Session and HttpRuntime.Cache had a baby.
Full Background: I have a ASP.NET website that was originally written for a single thread. Now I changed it so that certain actions will spawn a background thread and the browser polls a service to get status updates.
The problem I am having with this is that certain pieces of data are stored into the HttpContext.Session[] object (membership authentication token, for example). These pieces of data need to be unique to each user and accessible to the background thread. Session is not available to the background thread.
I am aware of HttpRuntime.Cache but that would require micromanagement to segment out the users and to expire it at the same time the session is expired. Session, on the other hand, automatically expires this things at the right times that I want it too and is already used by things like the SqlMembershipProvider.
My question is, is there something that behaves similar to the Session but exists in the global scope?
how to get sessions in the global.asax, but I still cant get it to work...for some reason my session throws NullExceptions..the sessions are set from another page add looks something like:
[Code]....
And once I try to get those session values I do the following in the Global.asax:
[Code]....
But as I said, for some reason I get a NullException once I try to get the values...and they do have the same session-name,so they shouldn't be null..
I want to use something better thatn using the session to store global values, because it has somw problems

View 5 RepliesI'm using VS2010 and created a simple asp. web forms application, using Development Server to test it. I try to store user data - queried from sql server - in the session, since I don't want to access database in every request. I'm using the 'Application_AuthenticateRequest' and the 'Session_Start' methods.
First round:
AuthenticateRequest called. The following code ran:
[Code]....
The _current variable is a private static field published through a static property. In the first round the Session is null, and I think it's ok because the Session_Start not called yet. The Session_Start looks like this:
protected void Session_Start(object sender, EventArgs e)
{
Session["EMPLOYEE_DATA"] = EmployeeFactory.Current;
}
In the next round the Session_Start is not called of course but in the AuthenticateRequest I can't access to the session. The HttpContext.Current.Session is null and the this.Session reference throw a HttpException says the "Session state is not available in this context".
However I can access the Session from any of the page_load events but it's a bad practice I think that I put authentication every page_load.

View 1 RepliesI have a method in one class file with defination like this which gets the user id of logged person.
public string GetUserID(HttpRequest req)
{ .... }
I need to call this method in global.asax and save that value in session. I need to use this session value i need to use this Session value and assign that to label in Masterpage. I did not use global.asax before. And what should be the input to method... i have seen only Request is have the returntype HttpRequest. So i thought of giving that.
I'm getting a very peculiar problem with my asp.net application, it took me an age to track down but I still don't know what is causing this behaviour.
If I set a session variable in the Application_PreRequestHandlerExecute event, then my external JavaScript files are ignored, and therfore causing a raft of errors. I have simplified the problem below.
E.g.
I have file called JScript.js containing the code:
function myAlert() {
alert("Hi World");
}
And in my Default.aspx file I reference the js with the code:
<script src="JScript.js" type="text/javascript"></script>
And in the body onload event I call the myAlert() function:
<body onload="myAlert()">
And finally in the Global.asax file:
Private Sub Application_PreRequestHandlerExecute(ByVal sender As Object, ByVal e As EventArgs)
HttpContext.Current.Session("myVar") = "MyValue"
End Sub
If you run the Default.aspx file you will see the js function isnt called, however, if you comment out the line of code Global.asax then the external js is called and the function executed when the page loads.

I also enabled SessionState in Web.config by addind following line:
<sessionState mode="InProc" cookieless="false" timeout="120" />
And when I run the application I'm getting this exception:

My ASP.NET intranet web application uses Windows Authentication, and I would like to record the following details:
1) Windows ID
2) Session Start Time
3) Session Stop Time
4) URL being browsed to (optional)
I've got some basic code setup in "Session_Start" method of the Global.ASAX to log session start times (seen below), but that's it so far. I have the feeling this is a primitive approach and there are "better" ways of doing this. So I really have two questions:
1) Is this the right way to go about doing this? If not what are some other options?
2) If this is the right way, do I just need to drop some code in the "Session_End" method to record the time they exit, and thats a complete solution? Does this method always get called when they close the browser tab they have the site open in, or do they have to close the entire browser (I don't have logout functionality)? Any way users can skip over this session end method (or start for that case)?
