we do have incidents that two different users signing on the same website and seeing other's account, one possible reason is the session id assigned to each sign on user got a collision - although the possibility could be extremely low, but in our case it is not acceptable as long as it is possible. So I am looking for a 100% absolutely secured session id?

View 1 Repliesdo you guys know a .net ListView-Replacement which can be highly customized?I am developing an app which is similar to a "todo" list.I want to be able to customize almost every visual detail of the list so I get something like this: I want also to be able to reorder items by mouse + I need drag&drop.If you don't know any ListView, maybe you know how I could make my own listview like this one from scratch?
View 3 RepliesI have some code I've written that has worked sporadically, and I don't understand the reasons why it succeeds or fails. The code in question is fairly straightforward, a single call to CreateFile() from VB.NET;
Dim Handle As Integer = Win32.CreateFile(KeyboardPath, GENERIC_READ Or GENERIC_WRITE, _
FILE_SHARE_READ Or FILE_SHARE_WRITE, Nothing, _
OPEN_EXISTING, &H80, 0)
The problem is that when I call this, I get the win32 error ERROR_ACCESS_DENIED, but if I remove the GENERIC_READ request, the handle is granted just fine. This has happened before (on a different machine), and I'm completely stumped as to what sequence of events would result in the ability to write to a device and not read from it. The device in question is a Logitech G510 keyboard, and this code has worked fine before on a Vista 32-bit system (I'm now testing it on a Win7 x64 system and fixing all the compatibility issues I can find).My question is, what can cause CreateFile to sporadically fall back to only allowing write access, what am I doing wrong that's causing it to do so, and how would I go about fixing the issue? I've included the full function below - note that with ONLY the GENERIC_READ flag passed, I also am not allocated a handle (same error)
As reference, the particular device path I've been using is \?hid#vid_046d&pid_c22d&mi_00#7&1a08be07&0&0000#{4d1e55b2-f16f-11cf-88cb-001111000030} (This is for a Logitech G510 gaming keyboard)

Dim oControl as Control
For Each oControl In Me.Controls

the thing its that i doesnt enumerate the child objects for example..
if the form has a tabcontrol, it will spit only Tabcontrol1 but i want to enumerate everything contained in all the form even of theyr childs of other objects.
I am attempting to move a highly referenced class from one namespace to another. Simply moving the file into the new project which has a different root namespace results in over 1100 errors throughout my solution.Some references to the class involve fully qualified namescape referencing and others involve the importing of the namespace.
I have tried using a refactoring tool (Refactor Pro) to rename the namespace, in the hope all references to the class would change, but this resulted in the aforementioned problem.Anyone have ideas of how to tackle this challenge without needing to drill into every file manually and changing the fully qualified namespace or importing the new one if it doesn't exist already?
I am making a crosshair(for a game) which needs to be absolutely topmost!//. This can only be done if the form's topmost property is true, and the next second false, and then true...etc..
But is there a possibililty to make sure your form is absolutely topmost.. Or make another program/application not topmost so that yours is.
My questions is only about the topmost not about the rest of the application because I have made everything already.
I have a customer intranet (ASP.NET / VB) thats instantiating an asp.net session checking various things in the dblogin process. The Intranet has various sub-systems.The marketing sub-system requires an app_role to be assigned to the Intranet user for them to view the section.I need to create a new booking form for this section but the code appears to use a generic form which is use throughout the site in various other sections. So its not a good idea to ammend what is currently there.Create a new application in C# / ASP.NET and also in IIS. (rather than a new site, create an app within the Intranet site in IIS)Will I be able to check for the session thats currenting set in the cookie?If the session is open then the user is able to see the Intranet and I assume I will need to do some checks for the app_role too.I am simply going to put the URL for the app in the menu for marketing and then do another check just incase someone gives the URL to someone who doesnt have access to the menu.Will i be able to check and use the cookie thats been instantiated by another application?

I am using VB .Net to access the eBay API and store all completed orders in a database. This database is then fed into a proprietary shipping system, which can not handle an order number larger than 20 characters. eBay returns an order number like so 230407279314-680141236013 which is too long. The order number is always 12 numbers a hyphen and 12 more numbers. What I need to do, is turn this (the result can be alpha numerical) into a shorter, unique order key to store in my database alongside the true orderId (so that this can be referenced by the shipping software instead of the actual order number). The reason for the 20 character limit is the barcode algorithm used. Is there any way to achieve this in VB .Net 2010? This number can be anything unique, so long as it does not exist already (even a good uniqueid function would work, but I would have to query the database to make sure it isn't taken)

View 2 RepliesI 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.
