For the following code, the method "GetPerson" has no explicit argument (except
self).
class MyCOMObject:
_public_methods_ = ["GetPerson"]
#_reg_clsid_ = '{44ee76c7-1290-4ea6-8189-00d5d7cd712a}'
#_reg_desc_ = "My COM server"
#_reg_progid_ = "MyCOMObject"
def get_person(self):
person = Person("haha", 45)
wrapped = win32com.server.util.wrap(person, useDispatcher =
my_dispatcher)
return wrapped
When calling from VBA, like below , it works fine.
Set o = CreateObject("MyCOMObject")
Set p = o.get_person()
However, when calling from C++, or Delphi, the following error will be thrown:
"TypeError: MyCOMObject.get_person() takes 1 positional argument but 2 were
given"
Delphi code:
procedure TForm1.Button1Click(Sender: TObject);
var
o: OleVariant;
p: OleVariant;
begin
o := CreateOleObject('MyCOMObject');
p := o.get_person(); // error will be thrown
s := p.name;
age := p.age;
ShowMessage(s);
end;
The fix is to change Line 639 of policy.py to the following:
if len(args) == 1 and (args[0] == -2147352572 or args[0] ==
None):
return func()
else:
return func(*args)
