[python-win32] Problems with Python+COM and XP Firewall Manager

[Jens B. Jorgensen]

Interesting. I would think that would work actually. Hmm. Actually the 
reason that call doesn't work is because the InvokeTypes call is 
attempting to turn the argument (which is the INetConnection *) into 
VT_DISPATCH, which cannot be done since that interface doesn't support 
IDispatch. I'm not sure where the mistake was made but perhaps when the 
type library was processed it was assumed that the INetConnection 
interface would support IDispatch which of course it does not. I think 
this is technically a bug in makepy. You can actually fix this by 
modifying the hnet.py that was generated by makepy. Go to the line in 
there where it defines INetSharingConfigurationForINetConnection there 
is a line there with "InvokeTypes(0x6, LCID, 2, (9, 0), ((9, 1)"... and 
change the bit with "((9, 1)" to "((13, 1)" and now the code should 
work. If I had more time to spare at the moment looking at this I'd 
figure out a patch for makepy and send it on to Mark.
