It's the library of the Xcalibur, a propietary program used in proteomics. to
read spectra. They provide an API, and VB examples to access it.
The problem is happening with those methods that return and array, as the
others work fine.
I am using defaultNamedNotOptArg= pythoncom.Missing
Is there something else I should check?
In a try to workaround this, let me explain that this Xcalibur program comes
with another COM library that does the same but with a different API. In this
case, makepy.py accesses Filters is a class and its accessed as an attribute
of this class:
class IXDetectorRead(DispatchBaseClass):
"""IXDetectorRead Interface"""
CLSID = IID('{88536044-BF39-11D2-BD97-0060978EEB9C}')
coclass_clsid = IID('{88536045-BF39-11D2-BD97-0060978EEB9C}')
...
_prop_map_get_ = {
...
"Filters": (1, 2, (9, 0), (), "Filters", None),
It works fine in VB, but in Python I get an exception:
Traceback (most recent call last):
File "<interactive input>", line 1, in <module>
File "C:\Python26\lib\site-packages\win32com\client\__init__.py", line 455,
in __getattr__
return self._ApplyTypes_(*args)
File "C:\Python26\lib\site-packages\win32com\client\__init__.py", line 448,
in _ApplyTypes_
dispid, 0, wFlags, retType, argTypes, *args),
com_error: (-2147352567, 'Ocurri\xf3 una excepci\xf3n.', (0, None, None, None,
0, -2147473634), None)
I have identified -2147352567 = 0x80020009 = DISP_E_EXCEPTION
but -2147473634 = 0x8000271C which I don't know what this code means. Is this
an Xcalibur-specific error code?
In a previous mail I found that one guy solved a similar problem replacing the
None of:
"Filters": (1, 2, (9, 0), (), "Filters", None),
by the CLSID of the Filter's class. So I tried:
"Filters": (1, 2, (9, 0), (), "Filters",
'{8E2D2225-C0BE-11D2-BD99-0060978EEB9C}'),
but the exception is the same.
So, I have two libraries to access the data but both crashes for different
reasons.
I'd appreacite any glue that I could follow.

Yes, but that should be irrelevant.
