It is true that I call the python routine like that in vb :
toto = obj.SqVal(ty)
If I am understanding well I need to pass an array of 2x2 and I should
retireve an array of variant of 2x2
I tried to do that :
vb6 :
Dim obj As Object
Dim toto(1, 1, 2) As Variant
Set obj = CreateObject("Python.Fop")
Dim ty(1, 1, 2) As Variant
ty(0, 0, 0) = 1
ty(0, 1, 0) = 2
ty(0, 0, 1) = 3
ty(0, 0, 2) = 7
ty(0, 1, 1) = 4
ty(0, 1, 2) = 45
ty(1, 0, 0) = 1
ty(1, 1, 0) = 2
ty(1, 0, 1) = 3
ty(1, 0, 2) = 7
ty(1, 1, 1) = 4
ty(1, 1, 2) = 45
toto = obj.SqVal(ty)
but it is saying that the compiler can not assign the array toto at
the line toto=obj.SqVal() hum strange .
any ideas ?

Debugging COM objects is best done using logging module or at least
writing to a file during processing. You can review the log file
to see what was going on.

I just tried to replace the *val by SqVal(self,val) and call the
method in vb but it crashes down :
"when refilling safe array the sequence must have the same number of
dimension as the existing array"
my python code is now :
def SqVal(self,val):
##volr=[val[0][0][i] for i in range(size(val,2))]
##voli=[val[0][1][i] for i in range(size(val,2))]
##mat1=mat(volr)+1j*mat(voli)
##up=linalg.pinv(mat1)
##out=up.real.tolist()
##out.extend(up.imag.tolist())
return val
By the way Do you have any idea to debug the com server script ? ( I
would like to know if a can access the value in the function while
calling it from vb 6)
tahnks a lot !

This is the expected behaviour. Writing it completely in Python:
py> def SqVal(*val):
... return str(val)
...
py> ty=((1,3),(2,4))
py> SqVal(ty)
'(((1, 3), (2, 4)),)'
The *val parameter receives a tuple, whose elements are the positional
arguments used when calling the function. As you call the function with a
single argument, val receives a tuple with a single element.
Perhaps you want to write it as:
py> def SqVal(val):
... print val[0][0]
... print val[0][1]
... print val[1][0]
... print val[1][1]
...
py> SqVal(ty)
1
3
2
4
(Of course, if used as a Fop method, dont forget the "self" parameter)

passing an array of variant in vb to a python COM object = win32com bug ?
I have a python com object which contains a method to inverse an array
in vb 6 the definition of the class is :
class Fop:
_public_methods_ = [ 'SqVal' ]
def SqVal(self,*val):
#vol=(val[0][0],val[0][1])
#mat1=mat((vol))
#up=linalg.inv(mat1)
return str(val)#up
_reg_verprogid_ = "Python.Fop.3"
_reg_progid_ = "Python.Fop"
_reg_desc_ = "Python Fop"
_reg_clsid_ = "{30BD3490-2632-11cf-AD5B-524153480001}"
I pass to this method an array of variant which is the matrix to
invert like that:
vb6 code :
Set obj = CreateObject("Python.Fop")
Dim ty(1, 1) As Variant
ty(0, 0) = 1
ty(1, 0) = 2
ty(0, 1) = 3
ty(1, 1) = 4
toto = obj.SqVal(ty)
when I dispaly toto as str(val) I obtain the following tuple "(((1,
3), (2, 4)),)" which is not usable
Do you have an idea to explain this strange behaviour ?
thank you !
