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.

View 2 RepliesI have created a .exe that uses My.Computer.FileSystem and now receive an error "Open File - Security Warning" dialog starting:
"The publisher could not be verified."
The file is located on a Windows File Server under ADS on a mapped drive. It was created under VB2005 and the .exe was copied using Windows Explorer drag and drop to the mapped drive. If I select to Run the file I get a security error. Same problem happens with new Access MDBs stored on the same file server. I have backed off all the IE zone settings to no avail. ADS security properties look like I have permission to run OK.
Files (exe and mdb) run fine from the desktop. I'm guessing somehow the files are being flagged as coming from the Internet instead of from the LAN. MS KB suggestion indicates there is a file property that appears indicating Internet origin - that is not showing up. IE 7 Beta 2 is installed. This error is suspending project work!
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
Hi All,Out of the blue VS 2008 has started showing a security warning dialog every time I create a new project or open an existing one as follows:"The {application name} project file has been customized and could present a security risk by executing custom build steps when opened in Microsoft Visual Studio. If this project came from an untrustworthy source, it could cause damage to your computer or compromise your private information."Two options given are:1) Load Project for Browsing2) Load Project NormallyA 'More Details' button opens a message box with:"An item referring to the file "" was found in the project file "C:UsersAdministratorAppDataLocalTemporary ProjectsWindowsApplication1WindowsApplication1.vbproj". Since this file is located in a system directory, root directory or network share it could be harmful to write to this file."1) I havent changed any settings since before getting this error and have kept all directories the same2) file locations are in "C:UsersAdministratorDocumentsVisual Studio 2008" - with full permissions3) Vista UAC is turned off4) I am using the Administrator login5) I tried Tools>Options>Projects and Solutions>General - and un-checked "Warn user when the project location is not trusted" -

View 5 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 3 RepliesWhen I send a mail from my external program through Outlook, then I get the security warning.
I've tried bypassing it with secman and redemption, but both these tools doesn't allow the app to be "Any CPU".
I need the app to be Any CPU because it must be x64 on client and x86 in design (since designer doesn't allow inherited forms on x64).
So how would you go around Outlook security?
Should I write some kind of TCP-listener-Outlook-Addin and then send a TCPIP from client with mail info?

View 7 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?
View 1 RepliesI am writing a small visual basic application to install clean up tools quickly on any machines that we need to work on here at my workplace. I am using 4-5 cleanup programs that I have packaged into MSI's and have batch scripts that I am calling in my visual basic application to run them as silent installs. However, because I am doing the silent installs, windows always pops up with the "open file - security warning" and I have to click run for each individual program. I am wondering how to get around this from my end within the application. I know it can be disabled in windows but I am not wanting to have to go through a process on every machine that I run this program on. I would like to find a fix on the back end in my script.

I'd like to auto-register the common/simple services in my unity container. I think the cleanest way to do this would be via a custom atribute.I can then examine all the (abstract) classes in an assembly and register those types with unity.The piece of information I'm missing is the interface(s) that the class wants to be registered against
eg:
Public Class AutoRegisterAttribute
Public Property ForInterface As System.Type
Public Sub New(ForInterface As System.Type)

Having just spent ages removing all of the previous warnings, I don't really want to add a new one. Any idea how to get rid of it (aside from not using generics)?I don't know what details I'd put in the attribute, or what number to put in the project-level ignore list.
