[python-win32] GetNetworkConnections fails since a Windows update

[Steven Manross]

That happens here too in Win10/Win11 using your code.  It looks like Microsoft altered the COM object for you not to be able to do a GetNetwork or GetCategory on the connection object, but that seems odd since it basically renders the object pointless.

P.S. some powershell code doesn't seem to be able to access the GetNetwork function either.

$networkListManager = [Activator]::CreateInstance([Type]::GetTypeFromCLSID([Guid]"{DCB00C01-570F-4A9B-8D69-199FDBA5723B}"))
$connections = $networkListManager.GetNetworkConnections()

$connections |foreach {
    $_.GetNetwork()
}

Element not found. (Exception from HRESULT: 0x8002802B (TYPE_E_ELEMENTNOTFOUND))
At line:2 char:5
+     $_.GetNetwork()
+     ~~~~~~~~~~~~~~~

Hello.

After a recent update on Windows 10, I not able to tell exactly which, I've a strange behavior on a program that works fine since 2015 on thousands of machines...



* With this code :

def networks_private():
     NETWORK_CATEGORIES = {1: "PRIVATE",0: "PUBLIC", 2: "DOMAIN"}
     m = win32com.client.Dispatch("{DCB00C01-570F-4A9B-8D69-199FDBA5723B}")
     more = 1
     pos = 1
     connections = m.GetNetworkConnections()
     while more:
         connection, more = connections.Next(pos)
         if connection:
             network = connection.GetNetwork()
             category = network.GetCategory()
             try:
                 log('switching network interface in private mode')
                 network.SetCategory(1)
             except:
                 log("error switching network interface in private mode")
         pos += 1



* I get this error :

Traceback (most recent call last):
[...]
File "Frame1.pyo", line 163, in _init_
File "fonctions.pyo", line 201, in networks_private File "win32com\client\dynamic.pyo", line 522, ingetattr_
AttributeError: Next.GetNetwork



Regards, thanks.
