VS 2005 Insufficient Security Permissions To Set The System Time?
Jul 8, 2010
I'm working with a vb.net 2005 project that i converted from vb 6.0 last year. It's working fine in windows xp, but on vista and windows 7 i get an error saying 'Insufficient security permissions to set the system time.' Can you think of any way to replicate this error on windows xp? I'm trying to get a windows 7 box setup at work but I was wondering if there was anything I could try with xp in the meantime.

In a windows forms application I am attempting to read a file from a share into a filestream.I then start impersonating and write the stream to another share that only my impersonation account has access to.This works fine for small files. But if I attempt this on a 90 meg file I recieve a "Insufficient system resources exist to complete the requested service" error on the following line:
System.IO.File.WriteAllBytes(myLocation,MyByteArray)
Full Example:
Dim ImageData As Byte() = Nothing
Dim fsAttachment As IO.FileStream = Nothing[code].....

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

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.

Assume a .NET class library code that, for example, writes to the Windows registry. Then this code has problem to run over internet, because default Internet policy does not give access to write to the registry.By adding a RequestMinimum statement in the assembly we can specify that the code requires permission to write to write to the registry. This will not alter the fact that the code does not have the permission, but will stop the assembly from loading; the runtime will throw a System.Security.Policy.PolicyException and identify the permission that is required.Do you now any other examples of using evidence, security policy and permissions (the key elements of code-access security) to prevent an assembly from loading on a web server?

I am building a permissions system in vb.net against the normal Windows Server file system. Have not decided on the best method, but is there a way to get access to some kind of internal GUID that Windows might store for a folder. If I just store the path for security, then it quickly becomes very hard to update a database storing path information to get security information. If a folder had some kind of internal GUID structure that would be great. Is this available?

Now i'm working with users so for each user there are many permissions like add, update, view and delete, but i was thinking create a bit type data for each authorization, then i would load each one with 0 or 1 and show only the authorized form for the user. Could I do this? or there a better way to do the same?

I have a program that uses a font that's not stored on many computers, so the font comes with the program, in its resources. Before I was writing to a file and loading the font from that location, but I remember now that sometimes you don't have permission to write to a file. My application will not write to any other files, and having this font available is very important. So, I decided to use Marshal.AllocHGlobal() to store the font in memory, then read it back. (I'm using a PrivateFontCollection object to store these fonts.)Does Marshal.AllocHGlobal() require permissions? Is it more likely that it will throw an exception than IO.File.WriteAllBytes()?

My problem is that i want to be able to set permissions for users as they log into our software. When the program loads the users get the logon screen. Then once authenticated (in SQL)they can access all of the forms. What i want to know is can i create some sort of access levels. So for example if i was to login to the software as admin then i can see the "system" menu whereas if i login as someone else they cant see the menu. Can it be done in SQL, like my authentication. Even if we added an extra column called access then if it was set to 0 you are an admin and if it is set to 1 you are standard.

I realize AesCryptoServiceProvider is part of .NET framework 3.5. I do have 3.5 installed. However, (I can't believe I don't know this), how can I utilized Framework 3.5 so I can access the AesCryptoServiceProvider? Currently, it points to 2.0.

I have an app written on an xp pc which I want users to run on Vista
The app needs to delete a file on a portable drive in a particular folder
This folder was created on the xp machine and copied to the portable drive
The app will not delete a file in this folder on Vista but it will on xp
When I check folder security on vista (which does not exist on xp) I find that the folder does not have full control assigned
my app will write a file to that folder & delete it but will not delete a file put there from the xp pc
If I change the security in vista to full control it works
what I want to do is see if the folder has full control when the user selects it and advise them they need to alter security as I can not do it in the program
basically I want to advise them the moment they select the folder, not when it fails to delete the file after entering misc details in the app which are reuired before the file is deleted.

I want to add a feature to my trial version of the application. After first activation, I want to make it limited to 90 days. But I am concerned about user's changing the date of system hence deceiving my application. Is there any possibility to make it fool proof in a way that even if user takes the calender back, application expires after 90 days of first activation? First activation date has been saved in the database.

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.
