I recently did a clean install of Windows 7 Home Premium and a reinstall of Visual Studio Professional 2008. I can't find the Framework Configuration anywhere. I have looked on the Start Menu and in the Control Panel and in Administrative tools. I need to find it so I can fully trust the network where my projects are located.
View 3 RepliesWhen I try to run my DLL in Autocad, I got the message below.Application attempted to perform an operation not allowed by the security policy. To grant this application the required permission, contact your.I know there are many threads on this error, but Im not sure about one thing.Can I resolved this on our FilesServer or I have to do something on each computers that will use the DLL ?
View 3 RepliesAssume 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?

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 ?

View 4 RepliesThis 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.

View 6 RepliesI 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?

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 need to create a software installation group policy using VB 2010 (or C# for that matter).
I have a project/app released which references a dll from the GAC folder. The project is looking for version 1.0 of the referenced dll.
I want to release version 2 of the dll without having to re-release the app and have all users re-install.
I had thought if i deployed a policy with the new dll which redirected calls for the dll to the new version this would be ok. However I think I am missing something. IT seems the redirect is not working as when I test on a users machine, give them the version 2 dll and the policy dll but take away the version 1.0 the app fails. It seem calls to the missing dll are not redirected by the policy dll to version 2.
Policy config which is used to create the policy.1.1.CorpReportsClassLibrary.dll
is as below.

how to build something like the following:I have an application that will reside on Kiosk style PCs that are out there in public settings. While the application is running on the Kiosk I'll need to restrict the access to certain PC features (reboot, command prompt, download files, etc.) so they don't mess with the PC. I need to build a Windows Installer that deploys the application and does all the set up needed to lock down the PC. The installer needs to do all the work; there can't be any manual steps besides running the installer. The installer will install the application, this part is standard. In addition it will create a local user and use Local Group Policy Objects to restrict the user's access to the machine. Then the machine administrator will log in as that local user and run the Kiosk application under this account. The hope is that the account is locked down and people playing with the application won't be able to stop the application or do anything malicious to the PC.I have been looking for a way to create GPOs in C# code. This way I can implement the GPOs as a CustomAction in my installer. So far I am not finding the right API for GPO management so I'm starting to wonder if I'm even on the right track.If you know of a nice solution for how to accomplish the Kiosk lockdown via a Windows Installer or you know something about managing Group Policy in a C# application

how I could retrieve the date/time of the last Group Policy update. I have a crude routine that will search the Event Log for Event 1704, but this runs slower than I'd like. I was hoping there might be a way to get this info via Registry, WMI query, etc. that would work faster in my VB2010 program.
