Hi,
I'm trying to use an Automation interface from Python, but I'm stuck with
the following error calling a method:
The IDL for the method is:
HRESULT QueryAvailableProperties(
[in, string] BSTR ItemID,
[out] LONG *Count,
[out] SAFEARRAY(LONG) *PropertyIDs,
[out] SAFEARRAY(BSTR) *Descriptions,
[out] SAFEARRAY(SHORT) *DataTypes );
The MakePy version is:
def QueryAvailableProperties(self, ItemID=defaultNamedNotOptArg,
Count=defaultNamedNotOptArg, PropertyIDs=defaultNamedNotOptArg,
Descriptions=defaultNamedNotOptArg, DataTypes=defaultNamedNotOptArg):
return self._ApplyTypes_(0x60020017, 1, (24, 0), ((8, 1), (16387, 2),
(24579, 2), (24584, 2), (24578, 2)), 'QueryAvailableProperties',
None,ItemID, Count, PropertyIDs, Descriptions, DataTypes)
and the code I'm using to call it is:
>>> a = None
>>> b = None
>>> c = None
>>> d = None
>>> print x.QueryAvailableProperties("Test.Item1", a, b, c, d)
Traceback (innermost last):
File "<interactive input>", line 1, in ?

File "C:\Python20\win32com\client\__init__.py", line 334, in _ApplyTypes_
return self._get_good_object_(apply(self._oleobj_.InvokeTypes, (dispid,
0, wFlags, retType, argTypes) + args), user, resultCLSID)
com_error: (-2147352571, 'Type mismatch.', None, 3)
Any ideas ?
