Hi everyone! I'm trying to automate an operation with Alibre Design (http://www.alibre.com) via COM.
It is mostly working, except for a call to a method that accepts a single optional boolean parameter. When I try to call this method, I get an "Invalid number of parameters" exception. Here's my code: ---------------- import win32com.client import pywintypes try: # Check if Alibre is already running h = win32com.client.GetObject(Class="AlibreX.AutomationHook") except pywintypes.com_error: h = win32com.client.Dispatch("AlibreX.AutomationHook") h.Initialize("", "", "", False, 0) root = h.Root # Open a file and get its mass f = root.OpenFile(path_to_file) d = win32com.client.CastTo(f, "IADDesignSession") mass = d.PhysicalProperties(2).Mass f.Close() ---------------- The exception is triggered from the last call.. makepy generates it in this way: ---------------- def Close(self, saveSession=False): """Closes the session and saves the modified session and sub-sessions, if any, to their original folder locations, if the saveSession flag is set to true. Use SaveNew or SaveAs if this session is being saved for the first time""" return self._oleobj_.InvokeTypes(7, LCID, 1, (24, 0), ((11, 49),),saveSession ) ---------------- This matches the documentation of Alibre's API, and what I get when I try to inspect the corresponding DLL using Reflector. Any idea on what I could try? Thanks for your time!
