C# - ASP.NET Directory Access With Role Based Security?
Apr 27, 2011
I have an ASP.Net portal like application with multiple roles. I have placed the subpages of that role in its own directory adding a web config with an authorization allowing only that role. I have css and javascript in the root directory that can not get access inside the protected role folders. How can I allow these folders css/js to have access to all roles. Sorry if this is easy question I have searched but I am rather new to ASP.NET

I have the membership provider setup and its currently pointing to a SQL database on my machine. The role based access works and I have a menu that is security trimmed. The user can only get to pages that they have access to.When an anonymous user tries to get to a page that they dont have access to it brings them to a login page so that they can login. That is fine. But when a logged in user tries to get to a page they dont have access to(Usually by typing in a URL) it brings them to the login page again asking them to login(except there already logged in. I'd like to either take them to a different page or somehow tell them they don't have access.

I have a page with a gridview. The gridview has "Enable Editing" and "Enable Deleting" checked by default. I want to be able to "uncheck" either of these in the code-behind page_load event.
I found this SO question but this hides the whole commandcolumn. I only want to hide the "Edit" or "Delete" hyperlink based on the role of a user. How would I go about doing this?

I have a webForm app that registers a user in the database based on the information provided with a web service, auto-generates a random password and username, and e-mails the user a link to take an application based on the marketing company selected. How do I get only the currently logged in user's groups to show up under the MarketingCo_DropDownList. Each user allowed access to the system will have membership in at least one of the marketing groups as defined by the web.config. For example, a user that is currently logged in and belongs to the BIG group under location "algACOMP_user_BIG", will only be able to see BIG in the Marketing Company drop down list. A user that is currently logged in and belongs to the NIS group located under "algACOMP_user_NIS" will only be able to see NIS in the Marketing Company drop down list.
Here's my best guess (located under Private Sub GetMarketingCompanies() method in default.aspx.vb):
If InStr(WindowsIdentity.GetCurrent().Groups = "AMG", item.MarketingCompanyShort = "AMG", CompareMethod.Text) Then
marketingCo.Items.Add(String.Format("{0} | {1}", item.MarketingCompanyShort, item.MarketingCompanyName))
For Each item In ac1

I'm writing an installation program that needs to create a new Folder in the "Program Files (x86)" folder. I'm getting the following security exception:
System.Security.SecurityException was unhandled
Message=Exception from HRESULT: 0x800A0046 (CTL_E_PERMISSIONDENIED)
What do I need to do to get around this issue and create the desired Folder?

I'm creating a windows application form in vs 2005 for a client.. It's a data-tracking application. I have a few questions.The client wants a logon screen to be added into the application (at least any way or method that'll ensure that security was applied). My question in regards to this topic would be; Is it necessary to create a logon screen (or even a user authorization) for a windows form? I realize that in a webform project, security should always be considered and should be applied in all areas. Although with a windows form, I thought you can authorize who can gain access to the application by defining which workstations to install the final production release of the application (when its time to deploy the file). Is this correct?
My next question is, what is the best method to exporting data from EXCEL to SQL tables? I have many Excel files that I'd like to take portions of data from each file and insert them to there proper table.
The last question is about deploying a windows form application. As you can tell, I don't have much experience when it comes to developing Windows Form projects. Anyways back to the topic, When deploying a project, does it provide a .EXE file (installation package) to install the application on the workstation? Or is it a .EXE file of the application, where you can run it and no need to install anything?

I work on a vb.net winforms app where we currently are using simple roles for security. We enable/disable specific controls based on if the current user has the required role. We are to the point where this is no longer granular enough.Our application is based on different physical locations we call sites. A user might have permission to do something (for example, edit a site's configuration) at one site but not another. Therefore, we now need to lookup permissions based on current user AND current site. Also, a certain user's permissions may be very specific to themselves ie. no other user's permissions are exactly the same as another user's. Therefore we need a security model that's more permissions based rather than role based.
What's the best way to design a new permissions model that can meet these requirements? I want to make sure that it's easy to implement the checking in the code (I don't want a million if statements sprinkled in our SetUIPermissions methods) and we don't want to have to update every user (400+ and counting) each time we add a new permission. Because of this last requirement I think we need to keep the idea of roles but possibly add/remove exceptions for particular permissions for specific users

I need some help in the creation of a program to generate a security code based on the current date. I need to create something that first multiplies the MMDDYY (ie X=MM * DD * YY) then also adds the MMDDYY then finds the remainder and then multiplies but a specified number. I would like to create a small program that sits in the system tray with this code displayed. The code will always need to be 6 characters, so I might need to pad it with zeros. It has been years since I took basic VB, and I am really rusty.

One of my application is taking a lot of time on Windows 7 compared to XP. What application basically does is it creates some PDF files reads the content and emits on a form and then deletes the files. I ran ANT profiler on both XP and Win 7, and i could notice some differences. On win 7 some CAS related methods are widely called and those method calls were missing on XP.. Is this the reason ?

This program is a small ADOX database with a single data entry Form. Originally written in VB 2005, it was copied into the VB 2008 Project folder. Opening the file in the IDE, it went through the Conversion process, nevertheless, because of the following error detailed below, the program will not accept any changes.
Error List: Warning 1 Unable to find manifest signing certificate in the certificate store. AppointmentsMissed (<the project's name) Under Security in the project's Properties Window these suggestions are made: Visual Studio was unable to determine the Code Access Security (CAS) permissions that are applicable to your project. The most likely cause is that your project references a strongly-named assembly that defines custom permissions, but that is not properly installed in the global assembly cache (GAC).
To correct this, try the following: 1. Ensure that any custom permissions defining assemblies referenced by your project have been properly installed to the GAC. If any of these assemblies have been rebuilt or have had their version numbers modified, you must install the new assemblies in the GAC. 2. Restart Visual Studio.

Trying to read key "HKLMSOFTWAREPoliciesMicrosoftWindowsWindowsU pdateAU" value "AUOptions" and get the following : A first chance exception of type 'System.Security.SecurityException' occurred in mscorlib.dll Error occurs in ReadRegistry key SOFTWAREPoliciesMicrosoftWindowsWindowsUpdate AU : Requested registry access is not allowed. This occurs in my vb.net application when application is run under an account called OPER in the USERS group. The application :
1/is on my PC's hard drive, its not a web app or on a network share
2/is launched via a desktop click
3/ has a manifest specifying executionlevel "AsInvoker"
It does not occur when the Application is run as an Administrator. It does not occur if I read the value with a non .NET program when logged in as OPER whch makes me think it is a .NET problem not a registry permissions problem. Examining "Effective Permissions" shows that my OPER login has query value permission.I need the application to be able to read the key like the non .NET application while running at USERS level.

I've got this program I'm working on in VisStudio2008. Basically, it accepts a password and executes an Access 2003 database using the Access 2003 runtime. I've got the thing looking up a password and all is good, but there's one problem those annoying Access 2003 and higher warnings about unsafe macros. Does anyone know a way to make sure those don't show up when the program starts?My client has a database that someone else wrote for her. She's not at a point where she could have it rewritten (believe me, I've tried to talk her into that). So I have to stay in Access but it's not very professional to have those warnings come up.

I am not sure about the semantic of "ApplicationDirectory" membership condition. I am trying to use it in the .NET Framework 2.0 configuration tool. The tool's explanation to it is as below:
The Application Directory membership condition is true for all assemblies in the same directory or in a child directory of the running application. Assemblies that meet this membership condition will be granted the permissions associated with this code group.All the other membership conditions such as strong name, hash, allow me to input some criterias, only the Application Directory has not. So how to use it?
