MVC Authorize Attribute Deny Access / Permission
Oct 25, 2010
I'm using the Authorize() attribute to secure my controllers/actions and want to only display the Login action to unauthenticated users - or to put it another way, deny access to authenticated users. I haven't been able to find anything on the web dealing with either denying permission or allowing negative permissions (i.e., ! LoggedIn)
MVC2, .Net 4
To clarify, I want something like this:
Public Class PublicController
Inherits ControllerBase
<Authorize()> 'Only logged-in users can logout
Public Function Logout() as ActionResult
[Code] .....

I made an app that will dump the tasklist because rogue likes to force kill executables, is it possible to deny the rogueware's force kill when I try to open a program I made or Deny access to the program the is trying to end it, to clean the infection? I have also read from a few articles and it suggested to create a service that runs under svchosts.exe. I also read about hiding the process in task manager but I doubt that would work, is it possible to deny the rogue software from accessing the close event handler within a VB.NET application.
The reason I am working on this is we get a lot of customers in our PC shop with a lot of rogue software attacks and desktop hijacks. Since I know that the rogue software closes cmd.exe; msconfig; and notepad.exe I made a small somewhat worthless app that dumps the tasklist into a txt file on the desktop then of course knowing notepad wont open I know I can open it with a trusted application that the rogue looks forward to.."Internet explorer".
I get the file name and its path from the text file and Click Start > Run... > Taskkill /F /IM <roguename.exe> and of course the rogue software will BAM! disappear and be killed, but see I am trying to accomplish this in Normal mode and not Safe mode to Deny the rogue of closing my application. It also speeds up the removal process dramatically

I am using ASP.NET MVC to build a site. I am using VB as programming language.I have couple of questions.
1 I have created a role "Manager". How Do I check if a user belongs to this particular role?
For now I am using If My.User.IsInRole("Manager") Then 'Direct to a view Else 'Direct to another view End If Is this the right way? 2 How to use the Authorize attribute to limit access to a Function?
I know in C# it goes [Authorize (Roles ="Manager")] but not sure in VB. Also can I define property to redirect a user who does not have "Manager" role to a particular view when trying to access this function .

My.Computer.FileSystem.DeleteDirectory("folder location here", FileIO.DeleteDirectoryOption.DeleteAllContents)
I created a program which was deleting a particular directory for me. The program was compiled and working. Today I run the same program...did not do any system updates and now it won't delete my specified directory. I ran tests to make sure the directory is there when testing...I keep getting access/permission errors.
I rebooted system, ran my application...still gave me error. I turned off Windows Defender...still got error. If I manually delete the directory...no problem.
Is there a way to get system permission to delete the directory? I am being given an 'access denied' error...I do not have permission. I tried running my application as administrator...no good. - VB 2008 Express - VISTA OS

How difficult would it be to have my application check for user authorization over a network?
If I have a php server, each time someone starts my application it should connect to the server and check the users computer name against a list of authorized computers, possibly using MySQL.

I am making changes to my companies internal paysite in order to come into compliance with the new credit card regulations. We have decided that when we get a split tender transaction that comes through we want to get the remaining balance along with how much was on the card to start out with and send that info back to the customer service rep with a message relaying the need for another payment source along with the remaining balance and the amount that was originally on the card.
Instead of chaining the transactions together with the split tender Id we have decided we would like to finalize each split tender transaction with a prior_auth_capture and then request the next payment source and amount and process that transaction in the same manner. I know that we are side stepping the functionality some but those are my orders.
My questions are, is this feasible and possible and how do you do this in code? I am using the C# SDK to implement this in VB.NET 2008
My thoughts are that I would have to process the transaction for the amount passed as a auth_capture transaction and then some how do the prior_auth_transaction with a zero amount or something?

I am new to .NET and I have created a login page, with a user Id and password. In my webconfig, I put the following code in to deny users who are not authenticated.
<authentication mode="Forms">
<forms loginUrl="Login.aspx" timeout="10" protection="All" />
</authentication>
<authorization>
<deny users="?"></deny>
</authorization>
What I am trying to accomplish is that when a user enters the correct information, I would like to store information small information about the user in a cookie, say for example if there an admin, manager, user, etc...Here is the code that occurs when the user click the submit button. The problem is that the page doesn't redirect to the page after user enter correct information.
If txtPassword.Text.ToLower = "test" Then
'Create a cookie
Dim cookie As New HttpCookie("UserInfo")
'Cookie variables
cookie("User") = txtUser.Text

In my web application we have many users. I want to set permission for each user. In our windows application we used Database to store the Permission(Insert,Modify,delete and View). In web application can anybody tell me about where to store the permission. Somebody told that if we use database it will take so much time? In the case of XML it is easy and not taking much time. But if the client set permission for number of users,then it will create problem?.
(Permission means in case of "Category" page which user can view the Category page,which user can edit information about category,which user can delete information of category,which user can add new category)

Modifying a registry key we could 'write-protect' our USBs, and I wanted to make a program that would do such but I am getting a permission problem in adding a registry key to the local machine. My development machine is Windows 7 Ultimate 64 bit but I would want it that it will be able to run on other OS like XP and 32 bits. My thought is that I will use autorun and run my program so that upon insertion it will become 'write-protected' and be able to re-enable it also using the program.
