Windows Vista & Internet Permissions?
Apr 7, 2009
I developed an assistance programme for an online game, and, in response to the users demands, I developed a secondary programme that downloads a zip file from a webpage hosted in a free Geocities server with the latest update for the programme and applies it. With the WinXP users it has worked perfectly, but with the Vista users, I've had a few cases where the update programme wasn't able to download the update, although everything worked fine with other uses.

With Vista we are having a permission denied error when an application tries to change properties of a file in Program Data folder... before replacing with a newer version of the file.Changing of security permissions for a standard user is not an option. Is there a way we can grant the premissions for an application developed in VB .net to give permission only to change properties of this file.

I have a user of one of my programs reporting that they get an "access to the path...is denied" error during this section of [code]He's using Windows 7 x64 with UAC turned on. The location of "FilePath" is a subdirectory inside Program Files (x86) in this case.I tried to reproduce the error on my Windows 7 x64 system by enabling UAC (I usually have it off) but the program worked fine. However, in my case, "FilePath" is not in a protected system folder like Program Files (where write permissions are not given to normal users without admin elevation).So I tried to recreate this situation on one of my Vista x86 Virtual PCs where the "FilePath" would be inside Program Files. However, my program again worked fine. It had no problems writing to the Program Files folder with a normal user account, UAC turned on and no elevated permissions required.
Thus, I am confused. Why does it work for me and not for him? I want to try an x64 virtual machine but I can't with the software I have (Virtual PC doesn't support x64 guest OSs, VirtualBox won't run the software that my program interacts with). So maybe you guys can help me instead. Are the write permissions for the Program Files (x86) folder different between x86 and x64, or maybe even Vista and 7?

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've encountered several scenarios when my application wants to delete an item, but is prevented from doing so by the operating system. So I've been wondering, is it possible to ask for elevated status after the application has launched? E.g. the application needs to delete a certain file, so it asks for confirmation and then deletes the file...

If I don't grant write permissions to the folder containing my exe file, I get an 'Access to the path binReleaseprogram.exe' is denied. But if I grant it write permission I don't get the error. Why would the executable need write permissions? I'm not writing anything to the root where it resides.

If I adjust permissions using the Security.Accesscontrol.DirectorySecurity on a directory, how can I make it so that subfolders automatically inherit the new permissions?
Brief overview of the situation is that my neighbors can't connect their Vista laptop to a shared folder on their computer running XP Home. They're getting access errors which I believe is because of the rights set on the folder. The problem is that XP Home won't let you adjust that and they're not upgrading.
I'm able to add the Everyone user to the directory I specify. But if I drag a new folder in or create a new folder, it does not have the Everyone user. Is there something I'm missing in this class that will let subfolders and files inherit the permissions?

i have created some shareware applications. I implemented the following mechanism for piracy protection. Before Windows Vista and Windows 7 i did write a dll file to the System32 folder with an encrypted license key. Also in the Registry under HKEY_LOCAL_MACHINE i inserted a registry key.
The problem is that with Windows Vista and Windows 7 due to the User Account Control (UAC) this is denied.
I want to ask : what other mechanism can be implemented ? Where should i store the encrypted key file and the registry key.
I want that the application can be installed for all users of a computer only once.
If i stored the key in the user's application data directory then another user could easily just install it under another user account. Also i do not want to put the key file in the application directory because that would be too obvious.
note that i create the registry key with my application and not with the installer.

I am wanting to update our current windows forms security to something a lot more flexible. At the moment we have a single column in thew users table which is named 'Access_Level', this field holds an int value (1 to 4) which is then use to determine users access to certain areas of the application. This worked fine when the system was small, but the system is growing rapidly now so I think it is a good time to update the user access and possibly introduce roles.

I've been struggling with this problem in VB.net for a while: whenever I try to access the My Documents, My video's or simular in Windows 7, I get an access denied error. The program that uses this code is a file-backup application, so it's important it can access everything. The app has admin rights, using this line:requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
To confirm, I also get a nice UAC popup when starting.The app accesses the files twice. Once to calculate the file size, and once to actually copy the files. Here is the file-size calculation code (that I found online:) Function GetFolderSize(ByVal DirPath As String, ByVal includeSubFolders As Boolean) As Long

I develop applications in Visual Basic.NET (Visual Studio 2005) for a long time on Windows Vista without problem.
Now, I'm changing my laptop, and the new has installed the Windows 7. So, I reinstalled VS 2005, taking care to install the Vista compatibility. Thus, the version of my current VS 2005 is 8.0.50727.867 (vsvista.050727-8600) SP2. And that is my problem.
When I ran the application in debug mode (F5) on Windows Vista, a windows appeared whenever there was an error, like below:
Now, on Windows 7, the application just shows a exception message in the Immediate Windows, don't showing any error window, continuing the application execution, as below:

I have an application that works fine on Windows XP. However I have taken the same application and made some modifications to it to run on vista the app loads fine etc.
the problem stems from trying to change a service in the registry under HKEY_LOCAL_MACHINESystemCurrentControlSetServicesDiagnostic Service Host
Start = 4 instead of 3 (which is what it is currently set to)
when the program tries to change it I get a dialog box with the information below. How can I makes the changes to the registry without getting these kinds of errors. I tried to get the Framework configuration tool but it talks about XP and Windows 2000 for VB.Net 2005 so I am not sure what to do... I should mention I have only been programming for a month...
Error details:
"Application attempted to perform an operation not allowed by the security policy. To grant this application the reuired permission contact your system administrator or use the Microsoft .NET Framework configuration tool. [code]...
