how to pass an array to a VB array via COM

[jelle]

Thomas,

No, i went over the syntax extensively. The syntax is
RS.AddCurve(points, degree), so 3 represents the degree of a bezier
curve. I'm doing fine with all types of functions which use 2 x,y,z
coords, but all arrays -tuple of tuples- fail. The odd thing is that
when i use RS.GetPoints() which is a method to get back user-defines
x,y,z points, i get a tuple of tuples containing these points. Though
when i write these back to the program,  all fails:

I admit posting this problem also to the more specific python-win32
group, though no response there yet...

>>>s = RS.GetPoints()
>>>s
((-7.0, -30.0, 0.0), (15.0, -24.0, 0.0), (-7.0, 12.0, 0.0), (14.0,
29.0,
0.0), (28.0, 10.0, 0.0), (20.0, 1.0, 0.0))

Cool, I get to choose points in the GUI, right back into python,
wicked!
Though when I send these points back to the app:
RS.AddPolyline(s)
The same error all over again:
