#350 arrayOfVariantOfBSTR in Python

[Mustafa]

Hi,

I have problem with an application which I try to automate with win32com. My problem is now, that a GetListOfDependantFile expects a arrayOfVariantOfBSTR byreference. I think this must be a list of strings. The VB Code is this:

Set Send1 = CATIA.CreateSendTo()
Call Send.SetInitialFile(myfile)
ReDim arrayOfVariantOfBSTR(500)
Call Send1.GetListOfDependantFile(arrayOfVariantOfBSTR)

How can I write this in Python for win32com ?

best regards

If you run makepy, you should be able to pass no params - the strings will be returned. Please show the code you use and the exception you see.

Hi marc,

this is my code:

import win32com.client
app=win32com.client.Dispatch('Catia.Application')
sendto=app.CreateSendTo()
sendto.SetInitialFile('c:\\...igteil.CATPart')
refs=sendto.GetListOfDependantFile()
print refs

When I use no params I get a type error or type conflict (with makepy):

Traceback (most recent call last):
File "C:\Python25\Lib\site-packages\pythonwin\pywin\framework\scriptutils.py", line 310, in RunScript

dispid, 0, wFlags, retType, argTypes, *args),
com_error: (-2147352571, 'Typkonflikt.', None, 1)

When I give a list as the param, the function returns the param as a tuple:

GetListOfDependantFile([])
returns ()
GetListOfDependantFile(['hello'])
returns (u'hello',)

Here is the traceback without makepy:

Just noting this is also being discussed in http://www.mail-archive.com/comtypes-users@lists.sourceforge.net/msg00144.html

It isn't clear this is still a problem - and the new builtin VARIANT support should make things easier.
