[python-win32] MemoryError: CreatingSafeArray when trying to use VB COM API

[Rex Corrovan]

I have a VB COM App I am trying to use.

I used makepy and it generated the wrapper. Then I go to use:

import win32com.client
o = win32.client.Dispatch("vbAPI.App")

o.myFunct(arg1=("test","test"), arg2=1, arg3=("test2","test2"))


The function in the makepy generated wrapper looks like this:

def myFunct(self, arg1=defaultNamedNotOptArg, arg2=defaultNamedNotOptArg, 
arg3=defaultNamedNotOptArg):
    return self._ApplyTypes_(1610809344, 1, (8, 0), ((24584, 3), (11, 1), 
(24612, 3)), 'myFunct', None, arg1, arg2, arg3)


The output I get is:

Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
  File 
"C:\Python24\lib\site-packages\win32com\gen_py\0A54F42C-8CBC-4C09-9F6B-C976C6476689x0x1x1.py", 
line 43, in myFunct
    return self._ApplyTypes_(1610809344, 1, (8, 0), ((24584, 3), (11, 1), 
(24612, 3)), 'myFunct', None, arg1
  File "C:\Python24\Lib\site-packages\win32com\client\__init__.py", line 
446, in _ApplyTypes_
    return self._get_good_object_(
MemoryError: CreatingSafeArray

I am baffled as to what is going on here. Anyone help?

Thanks

Rex
