Hi everyone,
I am struggling with a problem related to passing a
VARIANT argument to a COM object.
I am getting this exception:
TypeError: The VARIANT type is unknown (0000001e)
Here's what I am trying to execute:
- - - - - - - - - - - - - - - - - - - - - - - - - - -

Python 2.4 (#60, Nov 30 2004, 11:49:19) [MSC v.1310 32
bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for
more information.
>>>
>>> import win32com.client
>>>
>>> obj =
win32com.client.Dispatch('XTAPI.TTOrderSelector')
>>>
>>> obj.AddTest('IsBuy', True)

line 609, in AddTest
return self._oleobj_.InvokeTypes(4, LCID, 1, (24,
0), ((30, 1), (12, 1)),lpProperty, vValue)
TypeError: The VARIANT type is unknown (0000001e)

The makepy generated code-snippet is this:
- - - - - - - - - - - - - - - - - - - - - - - - - - -
- - - - - - - -
def AddTest(self, lpProperty=defaultNamedNotOptArg,
vValue=defaultNamedNotOptArg):
"""method AddTest"""
return self._oleobj_.InvokeTypes(4, LCID, 1, (24,
0), ((30, 1), (12, 1)),lpProperty, vValue)
- - - - - - - - - - - - - - - - - - - - - - - - - - -
- - - - - - - -
The AddTest method is documented to accept two
arguments: the first argument is a string and the
second is a variant. It returns nothing.
I am not able to pass anything as the second argument.
I have tried string, int, float,... but nothing gets
properly converted to variant,
and I get the same exception as above.
What does the above exception really mean? Regardless
of what I pass as the second argument, I get the same
exception message.
It just complains about unknown type 0000001e, which
probably corresponds to VT_LPSTR. But, why is it
trying to convert True to a VT_LPSTR?!
I'd really appreciate any ideas/help.
Thanks!
-Sumeet.
