.net - ASP.NET Change SessionID?
Mar 2, 2012
i must change the SessionID for an ASP.NET 4.0 Application (SessionID via Cookies) to have it run on 2 domains with the same Session [URL]... This will keep the Items in sync abov the 2 domains.
Therefor the Page will have iframes with an "setkey.aspx/ashx", which must set the new SessionID.
<iframe src="http://web1.local/SetKey.aspx?sid=<%=Session.SessionID%>" width="250" height="100"></iframe>
<iframe src="http://web2.local/SetKey.aspx?sid=<%=Session.SessionID%>" width="250" height="100"></iframe>
In the Session.Start the Session is already filled, so the SessionID keeps static via several Requests from the same Broeser.

Our solution is built on ASP.NET v1.1 framework. User is presented with login form, so upon providing credentials this information is posted back to the server. Upon postback SessionID changes and our application crashes as some information which is required for processing is stored in the cache and is identified by SessionID string as a part of the name.
This SessionID change happens absolutely randomly and only to some of the clients. Most of the time browser used to view the page and post info is IE8. I cannot reproduce this issue in our test environment, as SessionID is persistent though-out the whole testing process.
I've already checked all solutions, i.e.
Session cache is used on Page_Load to retrieve/store some information, so it's initialized and contains data stored. I've made a Health Monitoring check on Application_End event to capture any possible AppDomain crashes using Reflection and Diagnostics Libraries and retrieving ShutDownMessage from httpruntime object, but that's also not a case. Cookieless attribute of the sessionState in web.config is set to false (using URL to store SessionID is not an option)
All MS security and bug fixes are installed on the server. IIS Server settings are similar to the ones we use in Test Environment.

I have a website, that needs to not allow simultaneous logins. I am controlling that by cache. But, now I am unable to give them the option to log out the other session. Goal: is to allow them to login, and when they do, tell them that the current user is already logged in, and give them an option to close that session, so they can continue logging into the system (website).Have not found any way to terminate a specific SessionID. oh BTW, I do have the sessionID of the parallel session, just dont know how to kill that one. Again note, I do not want to close this current session, but another session whose SessionID I have.

I've been trying to find a way to determine if I need to launch an application or maximize it because it is already running for the current user. The problem I am running in to is since I'm using the For Each command the application though it now knows to open the external .exe wants to open multiple since more than one instance of the application is running without the same SessionID.
VB.NET
Private Sub OrderLaunchOrSwitch()
Dim CurrentSessionID As Integer = Process.GetCurrentProcess.SessionId
Dim hwnd As IntPtr

I have two combobox in a form: Cb1 and Cb2
When I load the form, Cb1 and Cb2 are connected to a bindingsource.
When I change Cb1, the code (below) changes Cb2 to show only the items according to Cb1
This is working fine.
The problem is when I change Cb1 , change Cb2 and click the save button..... Cb2 seems to be 'lost'...
I'm using VS2008.

I'm getting familiar now with using the Dataset Designer and how it makes for quick and easy updates and query of tables. I use to use the OleDB commands and leave the Connection String as a Global Constant so I can easily change it if the server name changes, or if we have to re-direct the .NET to another instance of the database.
But now that I use the Dataset designer I'm concerned that I maintain flexibility and support in the long run. how the Dataset designer works and where it stores it's connection string info? And how difficult that would be to update. It looks like I modify the App.config file, but I'm unfamiliar with this.
What am I getting myself into? It looks like a standard XML file. Is that it?

Ok, so I know I have to change the labeledit to true but that doesn't change the selected node to be able to edit, so how does that work?
Along with renaming I have it set to that a user can add a node. So once the node has ben added how do I let them rename it as it is being added and without being a prompt or inputbox? So lets say I cam clicked on a parent and they click add node, it adds it to parent but I have it so it is default "New" but I want them to edit it as it is added. I think it will be along the same lines as clicking on one and rename but I have to start some place.

I have 10 Comboboxes in a form. All these combo boxes have databound items which come from the same column in a table in the database (access 07) (Am designing a billing software, and these comboboxes show the items (10 lines of them).All these combos reside in one Groupbox.Now for the strange (scary/funny) part, whenever I change a value of 1 combo, all the other combos change automatically and show the same value as the one that was changed. (strange!).

I have a change calculator program that has two user inputs and 6 outputs. The user inputs how much money is owed, then how much money is received. IT will then display how much change you need to give back. It should also display the different types of currency that are available to give as change. Here is my code so far.

I'm working on a simple base form in which all the other forms in the project will inherit. This base form only adds 5 properties (at the moment) dealing with painting a gradient background. The problem I'm facing right now is when I change a property on Form1 (the test form) and click run it doesn't show that change. I also checked the .designer.vb file and when I make a change it's not added to the code behind file, I'm at a loss right now to why.

I am throwing some data out into Excel and am having some formatting troubles. I have 5 columns (date, time, a long number I don't want displayed in scientific notation - text is fine, text, text). I can get it all working with numberformat, however I have to do them different ways.
Date works this way cell.numberformat = "m/d/yy" and it formats it to say 3/1/11
Time works this way cell.numberformat = "h:mm AM/PM" and it formats it to say 8:07 AM
For the long number cell.numberformat = "@" and it doesn't change the format and it gets displayed in scientific notation
BUT if I use cell.style.numberformat = "@" it works as it should, but it messes up all of the date and time cells. Apparently when you use style.numberformat, it doesn't just apply to the cell you're working with. If I try using style.numberformat with the date and time formats, they don't change and are entered as if I didn't change the format at all.

I am trying to make a program that checks a certain process and changes one hex value to another. I want it to work a tad like some of those memory editors out there [art money, cheat engine, etc]... where it works only when the program is open, and it goes back to normal if you close and open the program again.
