Problem setting COM property using win32com

[Paul Prescod]

Bare in mind that I'm not a COM expert. We should probably be talking 
about this on the python-win32 list. But I see something strange in your 
makepy code...

In my makepy'd classes, default_interface is never a string.

class ResourceManager(CoClassBaseClass): # A CoClass
	# ResourceManager Class
...	default_interface = _ResourceManager

# This CoClass is known by the name 'XMetaL.Global'
class Global(CoClassBaseClass): # A CoClass
....
	default_interface = _Global

That's probably why you're getting the "cannot call string" problem. 
Look at the __init__ that's causing a problem. It probably looks like this:

class CoClassBaseClass:
	def __init__(self, oobj=None):
		if oobj is None: oobj = pythoncom.new(self.CLSID)
		self.__dict__["_dispobj_"]=self.default_interface(oobj)

I don't know how your default_interface got to be a string (perhaps a 
genpy bug, or hand-tweaking, or something else I don't understand), but 
I'd suggest you replace it with something like:

default_interface = _SmRecordList

or maybe

default_interface = ISmRecordList
