Python COM Server

[Bjorn Pettersen]

I believe your problem is that VB is calling SplitString with the
default argument (i.e. None), and then you are passing it (None) to
string.split, ie. your call is string.split(str(val), None).

I would probably code it like:

def SplitString(self, val, item=None):
  import string
  if item is None:
     item = ''
  else:
     item = str(item)
  return string.split(str(val), item)
