I am trying to write a program to switch off serial port enumerations
via the associated registry key. My code is:
RegistryPermiss ion permission = new
RegistryPermiss ion(RegistryPer missionAccess.W rite,
"HKEY_LOCAL_MAC HINE\\SYSTEM\\C urrentControlSe t\\Enum\\ACPI\\ PNP0501");
permission.Dema nd();
RegistryKey key =
Registry.LocalM achine.OpenSubK ey("SYSTEM\\Cur rentControlSet\ \Enum\\ACPI\\PN P0501",
true);
But the last line throws a Security Exception saying "Requested
security access is not allowed". What am I doing wrong?

Does the user account that this program is running under have the
permissions to change the registry node?
Colin,
There are two things I can think of. First, the user account you are
running this under doesn't have the appropriate rights to access the
registry key. The second is that you are running the application from a
network share, or from the internet, and as a result, .NET is sandboxing the
application so that it doesn't do any harm.

You don't have the right to open this key for write access, regular users,
including administrators, can only open this key for reading. This whole
registry tree is owned by the OS device manager, what exactly are you trying
to achieve?

Thank Willy. As I said above, I am trying to set the registry keys to
stop enumeration of serial devices. I need to do this to stop Windows
incorrectly recognising my serial device as a mouse etc.
The user account full administrator access. What else do I need? This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

Hi there
I need to be able to programmatically set permissions on registry keys using
VB / VBScript / VBA. So far I have had a look at doing this using the
WScript.Shell object, API calls, and WMI but the only one of these that goes
any where near registry permissions is WMI and that is only to get the
permissions of a key (cannot set). I am also quite happy for the code to
call an external program to perform the task but can't seem to...
