Problem using win32com
by unknown＠example.com Feb. 14, 2005

Feb. 14, 2005

Hi, A month ago, I decided to move from Delphi to Python/wxPython for a good deal of my development work, and for the past few projects (which included a full re-write of our point-of-sale system) I've had no problems and been very pleased with the move. We're Sage (accounting software) developers and frequently link into Line 50 using a Sage supplied COM server. In Delphi, the code to create the client and a workspace (which is required later) is as follows: SDO := CreateOLEObject('SDOEngine.10'); WS := SDO.Workspaces.Add('abc'); So naturally, I'd expect the following Python code to work: import win32com.client SDO = win32com.client.Dispatch("SDOEngine.10") WS = SDO.Workspaces.Add("abc") But at the last stage, I get an error: Traceback (most recent call last): File "<pyshell#4>", line 1, in -toplevel- ws=sdo.Workspaces.Add("ss") File "C:\PYTHON23\lib\site-packages\win32com\client\dynamic.py", line 154, in __call__ return self._get_good_object_(self._oleobj_.Invoke(*allArgs),self._olerepr_.defaultDispatchName,None) com_error: (-2147352573, 'Member not found.', None, None) So I used MakePy to generate the relevant Python interface code, and tried the following: SDO=win32com.client.gencache.EnsureModule("{ACE2C5EC-2EC0-4AEB-8B0D-27A5A1ED6421}",0,10,0) WS=SDO.Workspaces.Add("abc") But now I get: Traceback (most recent call last): File "<interactive input>", line 1, in ? TypeError: unbound method Add() must be called with IWorkspaces instance as first argument (got str instance instead) The relevant MakePy generated code looks like this: class IWorkspaces(DispatchBaseClass): CLSID = IID('{7075CC61-F056-11D0-A34B-000000000000}') coclass_clsid = IID('{7075CC63-F056-11D0-A34B-000000000000}') def Add(self, Name=defaultNamedNotOptArg): ret = self._oleobj_.InvokeTypes(2, LCID, 1, (9, 0), ((8, 0),),Name) if ret is not None: ret = Dispatch(ret, 'Add', None, UnicodeToString=0) return ret class Workspaces(CoClassBaseClass): # A CoClass CLSID = IID('{7075CC63-F056-11D0-A34B-000000000000}') coclass_sources = [ ] coclass_interfaces = [ IWorkspaces, ] default_interface = IWorkspaces What am I doing wrong? And more importantly, what can I do about it? I suspect there's a really simple answer which begins "Chris, you're being a fool...", but it's now pretty late, and I have other matters to deal with for the next few hours, so any help would be much appreciated. Regards, Chris

Larry Wall & Cults
by xah＠xahlee.org Jan. 21, 2005

Larry Wall and Cults (Lazyness, Impatience and Hubris) 200012 Dear readers, Did you know that throughout history there's this thing called cult? It is a very interesting phenomenon. I don't have time to expound and teach, but will try to brief you. These cults, are often lead by a single person. They form a group as small as a dozen to multinational octopuses (such as Scientology). Their creed varies from the mild in appearance (Dianetics) to appalling (flat earth, extraordinary life-after-death, impinging apocalypse scenarios, militant anti-government conspiracy, diabolism with human sacrifices ...). Don't think that i'm citing from some arcane books buried in libraries. These are real, and not difficult to find in real life. Some of these cult leaders, are so able to totally wash their member's brain, as to have them autonomously swear and volunteer to die for the cause of the cult. Occasionally, you'll even see mass suicide. You know, the world is not made completely of rubes. Somebody somewhere, will observe this phenomenon and study or report it as is. Big brother organizations, such as the FBI, is keen on these and very interested in benefiting from social psychology themselves. They are recorded in books too. Ever wonder why the library houses so many cold volumes of paper? This is one contributing reason. You might be interested to verify that sometimes. These brain-washing phenomenon, are not limited to fanatical life-and-death or otherwise dire beliefs. You see it work in all manners of human thought in the general sense. From culture formation to fashion to commercialism. Surely you have heard of Adolf Hitler and his atrocities of genocide? I must alert you, that a single person couldn't commit such a crime. You see, even if you are superman, you can only kill few at a time. You see, it is the people, people like you and me, who commit the killings willingly, by Hitler's teaching. You may say: "no, i won't ever do such stupid thing", well because you are very ignorant about social psychology. It is precisely innocent people like you and (not) me, who were lead by the radical leaders of supreme brain-washing abilities. The innocent mob were fervent in their leader's vision and beliefs to commit anything. You know the concept of war, right? We have two massive body of people committed to cut off other people's head or otherwise stick a knife in their bodies or bomb off an arm or leg. How did that happen? Well, it starts with patriotism for people like you and (not) me. Now, back to topic. In the computing world, there're also bad seeds with colorful creed taking innocent mobs forming cults. The three principal virtues of a programmer are Laziness, Impatience, and Hubris. Yes? How can we prevent heinous cults then? Stop bending truths. Education and rationalism. I'm starting my own cult to exterminate morons on this earth. Two things are on the top of my agenda: Unixism and Perl. -------- This post is archived at http://xahlee.org/UnixResource_dir/writ/larry_wall_n_cults.html Copyright 2000-2004 Xah Lee.

Advice to a Junior in High School?
by Howard Nease Jan. 18, 2005

Jan. 18, 2005

Hello, everyone. I would appreciate any advice that someone could give me on my future career path. Here is my situation: I am a bright Junior in a very well-respected private high school, taking almost all AP and accelerated classes. I am HIGHLY interested in technology, more specifically the field of Computer Science and software engineering. I have heard a whole lot about the fact that the market for software engineers nowadays is *HORRIBLE*, and that I should double major or perhaps go into a field of study in which I'm not very interested. I would be devastated were I to find the need to leave computer science. I love the subject, and I've wanted to be a computer scientist ever since I was 12 years old. Does anyone have any advice for me and my future? What should I study in college? Will the market for jobs get better? Do I have any hope at all of finding a decent-paying job in compsci? What languages do you suggest that I study (I'm already studying Python)? thank you very much for your help! --shn

OK, freelists.org *was* promising. The submit button on the signup page leads to a page displaying raw HTML with no content of interest. I guess the site is no longer active. John

Is there any module for parsing apache log files? O:-) I guess it could be done with regular expressions, but I'm not very gifted with them... :-) ----------------------- Fernando Rodriguez

My server is spitting out blank .asp pages which use python. If Python is not declared, the asp pages work fine. I just yesterday stepped up to Python 1.52 and the new win32all After the install, the blanks started appearing. All the paths look fine in registry. Any clues?

Python installation breaks Outlook Express
by M. Laymon Dec. 8, 2004

Dec. 8, 2004

I just installed Python 2.3.3 under Windows XP professional. After I did, my wife tried to access her email using Outlook Express and got the error messages: Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'incoming.verizon.net', Server: 'outgoing.verizon.net', Protocol: SMTP, Port: 25, Secure(SSL): No, Error Number: 0x800CCC0F Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'incoming.verizon.net', Server: 'incoming.verizon.net', Protocol: POP3, Port: 110, Secure(SSL): No, Error Number: 0x800CCC0F (No comments about Outlook, please.I have tried to get her to use a different email program, but she likes Outlook.) I checked the settings, then recreated her account in Outlook, but nothing worked. My Mozilla Thunderbird email client worked fine. Since the only thing I had done recently was to install Python. I used system restore to go back to the point before installing Python. After I did, Outlook started working again. Has anyone else seen this behavior ? Thanks. M. Laymon
