Hi experts,
Is there a way to determine if a particular registry key is writable (ACL)? My app needs to write to HKEY_LOCAL_MACHINE area under admin account. Before attempting to write to the branch, to avoid exception errors, I want to make certain that a specified branch in HKLM is writable.
I'm using Visual Basic 2005 for this.
Thanks.

Thanks, sirbounty :) For some reason, the regPerm.IsUnrestricted always returns "false" although the mentioned key is writable (tried using regedit.exe). I've tested with different branches also.
Perhaps I should try to write and then catch the exception. In that case, I'm wondering how to proceed to the next statement (in the try block) after an exception occurs in the previous line.
RegistryKey.GetAccessContr

An working example of the above would be great.
This seems to be a decent way of checking it - depending on your situation, but it worked for me.
I'm not sure what you're trying to accomplish exactly, but I denied access to my account for key Test and it dropped into the Catch. Specific error was: "Requested registry access is not allowed."
Dim regKey As RegistryKey = Registry.CurrentUser 'point regKey value to CU hive
Try
regKey.OpenSubKey("console
Catch ex As Exception
MessageBox.Show("The specified access to the key was not possible")
End Try
I'll see what I can find on the GetAccessControl method...
Dim dir As String = "D:\test\"
Dim Account As String = "BUILTIN\Users"
Dim act As Security.AccessControl.Acc
Dim fsar As Security.AccessControl.Fil
Dim info As IO.DirectoryInfo = New DirectoryInfo(dir)
Dim ds As Security.AccessControl.Dir
ds.AddAccessRule(fsar)
info.SetAccessControl(ds)

Hey sramesh2k!
I found this: http://msdn2.microsoft.com
which gives some good detail on registrypermission's.
You could use something like:
Dim strKey As String="HKEY_LOCAL_MACHINE
Dim RegPerm as New RegistryPermission(Registr
If regPerm.IsUnrestricted Then
'Process your changes here...
Hope that helps! (God knows you've helped me enough - lol)
