Bug for directory access

New User Posts : 5 Join date : 2008-10-18 Age : 28

This is a bug that i have since the first version of media companion
The application wont scan the directory because the folder contain an Unauthorized directory.
System.UnauthorizedAccessException: Access to directory 'V:\RECYCLER\S-1-5-21-602162358-308236825-725345543-1003' is refused
I have no idea how you did your function for getting the folders in a directory
but i did a little function that work without any errors

Code:: Function getdirectory(ByVal path As String) As List(Of String)
On Error Resume Next
Dim dirtoreturn As New List(Of String)
For Each dirtoadd As String In System.IO.Directory.GetDirectories(path)
dirtoreturn.Add(dirtoadd)
Next
Return dirtoreturn
End Function

this way if the directory cant be accessed its only going to skip the directory
if you have any question about that just ask

I'd rather avoid the exception altogether. I had a similar problem with the Sytem Restore Folder many versions ago.

I'll filter out the RECYCLER folder from the next version.

Are there any other system folders that you can think of that would cause an exception?

hummmmmm
i took a look into the object browser in vb2008 and you actually got in System.IO
in the DirectoryInfo you got

Code:: Public Function GetAccessControl() As System.Security.AccessControl.DirectorySecurity
Member of System.IO.DirectoryInfo
Summary:
Gets a System.Security.AccessControl.DirectorySecurity object that encapsulates the access control list (ACL) entries for the directory described by the current System.IO.DirectoryInfo object.

Return Values:
A System.Security.AccessControl.DirectorySecurity object that encapsulates the access control rules for the directory.

Exceptions:
System.SystemException: The directory could not be found or modified.
System.UnauthorizedAccessException: The current process does not have access to open the directory.
System.IO.IOException: An I/O error occurred while opening the directory.
System.PlatformNotSupportedException: The current operating system is not Microsoft Windows 2000 or later.
System.UnauthorizedAccessException: The directory is read-only. -or- This operation is not supported on the current platform. -or- The caller does not have the required permission.

For example "comodo internet security" don't allow to scan their virus vault. IMHO it's not a resolve to filter out special folder, you have to catch that kind of exception and solve the problem.
