Right now I am creating this session with the session key "PhonePart" which is also the name of object I am passing in as a parameter in first method. In subsequent methods, I use the the same name to retreive and clear session value. My problem is, this approach works fine If I instantiate a single object of the class where these methods are defined and using that object call the methods, but when I create another instance of the same class and calls for instance method AddToSession and pass that instance, it overwrites the session value stored by the first instance of the class as the session key is the same that is "PhonePart".
Considering this scenario, is it possible that I somehow grab the name of the object as string in the calling method say "AddToSession" and create a session with that name? If Yes, then I can do the same in subsequent methods and retreive session value and also clear the session specific to that instance name without affecting the other session values stored by other instances.

View 2 RepliesI need to send a cookie to the my web site's visitors and receive them back for information. For example when machine1 visits my site if not set I set a cookie with "user1", for machine2 I set "user2" etc.
Actually I need to retrieve the cookie back from my log file, so I thought if I do this it will be saved to my log file.
I do some dynamic stuff with UpdatePanel controls and it would be great to store stuff in a Session key and be able to grab it immediately with confidence in a Page_Init. Fantasy e.g.,
If(!isPostBack)
Session[pageInstanceID + "ThekeyIWantAccessTo"] = "123";
else
locVarValue = Session[pageInstanceID + "ThekeyIWantAccessTo"] +"";
I want something like this so that even if an individual user has two or more instances of that page open I am able to respond correctly to the immediate instance in Page_Init. Is it possible to achieve what I want or some facsimile of same? I know I can speculatively make an assumption and then check it in Page_Load when I have access to ViewState, but I would like something that approaches a best practice.
I am building an invoice system for a client and I am having trouble with the web forms related to the INSERT new order query.Basically I want to build up the order query from the selections made and then store it all in db at the end.
I don't want to use temporary db storage because it's a wasted trip to the server, I don't want to use session state because it's not data about the user I'm storing.... Unless I'm wrong, from what I've read I think query string is my best method since the data is not sensitive, it will just be primary keys and the like.
On the first form, the user will select the customer id from a datagrid displaying all customers. The next form allows them to choose the product from a datagrid showing all products and so on.... How do I pass this information across several pages?
My hope is at the end I will be able to take all the values and insert them into the corresponding tables to make up the customer order.

How could i get the total number of visitors of my website?
View 3 RepliesI'm using the following line of code to display the number of users currently logged on:
lblNoOfUsers.Text = Membership.GetNumberOfUsersOnline().ToString()
I'm still debugging my application so it's on the local server. As I debug and stop then debug again, eventually lblNoOfUsers.text turns to "0" instead of "1", even as I'm navigating my application. It only turns to "1" again if I log out and sign back in. It's almost as though Membership.GetNumberOfUsersOnline my login are referencing two different session states. How is this possible? Does asp.net create a new session state cookie each time I start debugging?
I have a website that has 10 aspx pages in it, and I'm trying to count how many users are on any one page at a time, and display that number on the web page. I have set it up to use an Application object ("TotalViewers"), and initialize it to 0 in the Application_Start event handler of the global.asax file. My reasoning (probably way off base) is to increment the count on each page load, and then decrement the count on each page unload. The increment part works ok, but when I add the code in the page unload event handler to decrement, it seems that Unload happens before the Page is presented to the client, so the value always stays the same (adds one in page load, subtracts one in page unload).
How else can I track number of users on each page? (simply, becuase I am still a beginner). I have already done some google searching and haven't come up with anything useful.
All my pages are being navigated via a TreeView control.
I want to control the login user to access our system. I authenticated all of users by using my own way in project. and I want to limit the number of user to access the system cncurrently. It means , We sell our project to customer as Licence software. If user buy it for three users, we will allow three conurrent login user to access the system. Our system allow our customer to create their own users as they wish. We don't want to control the user creation to use the system. but But we want to control the total no of current login user at the server as per our licence agreement . After reading some article, I see there are two main ways to control the no of users.
One way is to use the membership property in my project and then can count the number of online users by executing Membership.GetNumberOfUsersOnline Method.
If I use membership property, I think it is not ok at my project. As my understanding, the system will control the user creation if we use the memebership provider. I am not really sure whether I can use membership provider property to get my system requirement or not.

I m trying for counting Total No Visitors/Views(like in youtube) visits defalut.aspx.
But after trying a lot of codes i found it starts from 0 again when Application is closed.
i am wishing to count total number of visits on any particular page with also the ability to work when IIS reset is done, i think by using database we can solve it.
how to count total number of visits on any particular page?
I'd like that when a user logoff or his session expires, tha SessionID is no longer valid.
I've found the way to do it when the user logoff, simply doing:
[Code]....
But I don't know how to do it when the session has expired. Apparently, if the session has expired and the browser tries again to connect, the same SessionID will be recycled, and I want the server issues a new one, how can I do it?
Very new to ASP.NET and C# (somewhat knowledgable in PHP) I have an ASP.NET web application and need to manage access to pages based on a 'status' stored in a cookie. I would like to use the following code to create the cookie in a login method.
HttpCookie cookie = new HttpCookie("UserCookie");
cookie.Value = "status"; <-- this will be replaced with a variable once its working
cookie.Expires = DateTime.Now.AddHours(1);
Response.SetCookie(cookie);
My problem is that the only place I can put this code where it works is in the global.asax Session_Start method. It simply doesn't work anywhere else. I am checking the cookie creation in firefox options and see the ASP.NET_SessionId created but nothing else (This is all running on localhost).
Is the session status somehow interfering with the cookie creation? Do I need to configure something in Web.config? It would appear that the only time I can create a cookie is on Session_Start. Does anyone have any tips, perhaps I am missing something simple?
whenever any internet user visit any site on the world wide web, a session is created by the site for that useram i right? or is the session created by the iis on webserver?and this sessionwhat is it, yes i know session variables and how used them, but never understood what is this sessionwhat information does it have
View 6 RepliesI have a question about viewstate:I have created a simple little website in 2008 (.net 3.5)I have one page with markup that looks like this:
[Code]....
I'm creating a website where I want people not to be able to create link to certain pages.The site work like this: The user do a serch for a document and click the link to view it, then he can view the document. If the user somehow adds the URL to favorites he should not be able to view the document when he at some time later tries to view the document. In addition if the user sends the URL to other people they should not be able to view the document.
View 6 RepliesCurrently I am creating some dynamic controls on my page these can be hundreds of controls.Some of these will be available depending upon the input of the page so you can say the visibility will be different. This page in fact represents the dozens of pages.I want to create these pages from viewstate, e.g I have created 5 textboxes on page_Init() and then want to store these in Viewsate and next time if needed then load from the view state.In the other words can I create the and store the whole control object with all of the properties in viewstate, if so then how I will be able to accomplish this.
View 2 Repliesis it possible to create a new Session Id using C# and without using a Response.Redirect(...Page ... ). I want to create a new session Id on page load.
Reasons for doing so:
I have a testing application that creates IFrames to act as users. the problem I have is that with Multiple Instances (or Multiple IFrames running the same application "Default.aspx") all IFrame's are using the Same Session ID. I have variables stored in the Session ID that I need to be seperated from IFrame to IFrame. Ex:
IFrame 1 gets passed a query string of a client ID "1"
IFrame 2 gets passed a query string of client ID "2"
WHen the IFrame 2 gets loaded the session state of IFrame 1 inherits the IFrame 2's session's making the Client ID in Session 1 = "2". See what I am getting at?
I want to be able to have each IFrame create its own Session State. I guess there is 2 questions to this, 1.) is it possible to create a new Session State by abandoning the original and by doing so will that abandon both session ID's and just create an ID for both IFrames being the same ID? 2.) How can I do this if it is possible :-)
I'm attempting to create Data Access Layer for my web application. Currently, all datatables are stored in the session. When I am finished the DAL will populate and return datatables. Is it a good idea to store the returned datatables in the session?
