[python-win32] Array and CATIA
Hello,
we have a problem to pass an array to the GetComponents()-Method of
CATIA-COM-Object.
The method expects an array as method-parameter. The result will be written in
the given array. The array must be initialized with 12 elements. You can't pass
an empty array/dictionary to the method.
For unknown reason, this does not work. The array is not changed.
Does anybody has a solution for this?
Not working source:
# snip
CATIA = win32com.client.dynamic.Dispatch("CATIA.Application")
selection = CATIA.ActiveDocument.selection
# error checking
if selection.Count == 0:
CATIA.Statusbar = "exit1"
return
if selection.Item2(1).Type <> "Product":
CATIA.Statusbar = "exit2"
return
rootProduct = selection.Item2(1).Value
positionArray = [0.0,1.0,2.0,3.0,4.0,5.0,6.0,7.0,8.0,9.0,10.0,11.0]
result = rootProduct.Products.Item(1).Position.GetComponents(positionArray)
print result
# print result gives defaultvalues of positionArray,
# but should give other values
# snip
Thanks in advance
Andreas

[python-win32] Fw: Python COM and Photoshop
I thought I'd try this again -- still no progress on my debugging. From using Visual Basic it seems that the interface is expecting an array of type varint where each element of the array is another array. The inner arrays are two elements long (an x and y data point) I have also tried using the array module but I still get the same errors -- basically anything that I try in Python results in a error indicating that only a 1-dimensional arrays are supported -- which seems weird since the vbasic code is not making a single dimensional array.

Re: [python-win32] Python COM and Photoshop
One more thought -- I have tried both Early and Late binding COM calls and I get the same error message either way. >I thought I'd try this again -- still no progress on my debugging.

If possible, you should try and use a makepy based object. The easiest way is something like: from win32com.client.gencache import EnsureDispatch select = EnsureDispatch(select) # try and convert into makepy based object. If you can get that to work, you might have more luck, as python can determine the exact type of the variant from the type-library.
