Registry DeleteSubKey UnauthorizedAccessException ??

[Sagaert Johan]

Hi

Why do i get UnauthorizedAccessException when using DeleteSubKey ?
using DeleteValue does not produce an exception.

I don't know how to solve this since the CF does noe seem to support
System.Security.Permissions.RegistryPermission

Does the key you're attempting to delete have any subkeys itself?
Did you open the parent with write permissions?
Is this a WM device? If so, what key are you trying to delete?

Hi

Its a CE5 device, only the DeleteSubkey give me an exception, same when i
try to use DeleteSubKeyTree.
I have also written the code to create all keys and values and had no
prblems with that.


This is my code :

RegistryKey regkey =
Registry.LocalMachine.OpenSubKey(@"Drivers\BuiltIn\COM1\Unimodem", true);


string[] vals = regkey.GetValueNames();

foreach (string s in vals)

{

regkey.DeleteValue(s);

}

regkey.Close();

regkey =
Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"Drivers\BuiltIn\COM1",
true);

//delete key

regkey.DeleteSubKey("Unimodem");


vals = regkey.GetValueNames();

foreach (string s in vals)

{

regkey.DeleteValue(s);

}

regkey.Close();

//remove COM1 key

regkey =
Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"Drivers\BuiltIn", true);

regkey.DeleteSubKey("COM1");

regkey.Close();
