All the work producing the pywin32 package was done by Mark Hammond, Roger Upole and others. My small contribution here is to take the .chm it ships with and to unpack it into individual HTML pages.

The second... not quite. Python has a C API: http://docs.python.org/c-api/ which can be used to wrap external systems / libraries etc. and expose them as Python objects. This been in existence for as long as Python itself, and is used by pywin32 and many other projects to offer Python the ability to interface with toolkits, libraries and so on. ctypes was a later addition, courtesy of the ingenious Thomas Heller. It lets you interface with shared libraries directly from Python without having to write C code. This has several advantages: (1) you don't have to write anything externally and link it in; (2) you're insulated to some extent from compiler / type library incompatibilities; (3) it's *really* easy to use and drops things straight into Python. And several disadvantages: (1) you sometimes have to work quite hard to translate C-level examples into ctypes Python; (2) you can crash Python hard -- something it's very difficult to do with the language alone.

I found the following snippets in similar form on the internets somewhere (unfortunately, I don't know from where). First, make sure you have pywin32. Since you're asking on this list, I presume you already have it. Next, there's the instart() function, which installs and starts the service [1]. Then, there's your particular service. You can extend the base class below [2] and define the start() and stop() methods as you need them. For example, I have a python app that I run using Popen. My subclass looks something like: class MyService(Service): _svc_name = 'myservice' _svc_display_name_ = 'My Python Service' [...] def start(self): self.ric = Popen(self.COMMAND, env=os.environ) def stop(self): self.ric.terminate() Finally, the script that installs and starts the service for the first time: #!/usr/bin/env python import sys from yourmodule import MyService, instart instart(MyService) After you run that the first time, you can start stop the service from the management console or using the net command (using the name defined in _svc_name): net stop myservice net start myservice Hope this helps, -Roberto. [1] the instart function: import pywintypes from os.path import splitext, abspath from sys import modules import win32api import win32service import win32serviceutil def instart(cls, stay_alive=True): """ Install and Start (auto) a Service cls : the class (derived from Service) that implement the Service name : Service name display_name : the name displayed in the service manager stay_alive : Service will stop on logout if False """ try: module_path = modules[cls.__module__].__file__ except AttributeError: # maybe py2exe went by from sys import executable module_path = executable module_file = splitext(abspath(module_path))[0] cls._svc_reg_class_ = '%s.%s' % (module_file, cls.__name__) if stay_alive: win32api.SetConsoleCtrlHandler(lambda x: True, True) try: win32serviceutil.InstallService( cls._svc_reg_class_, cls._svc_name_, cls._svc_display_name_, startType = win32service.SERVICE_AUTO_START ) except pywintypes.error, msg: # error 1073 is for 'CreateService', 'The specified service already # exists.' if we don't get this error, raise it if msg[0] != 1073: raise try: win32serviceutil.StartService(cls._svc_name_) except Exception, x: print x.__class__ print str(x) [2] The base service class import win32api import win32event import win32service import win32serviceutil class Service(win32serviceutil.ServiceFramework): _svc_name_ = '_unNamed' _svc_display_name_ = 'Python Service Template' def __init__(self, *args): win32serviceutil.ServiceFramework.__init__(self, *args) self.log('init') self.stop_event = win32event.CreateEvent(None, 0, 0, None) def log(self, msg): import servicemanager servicemanager.LogInfoMsg(str(msg)) def sleep(self, sec): win32api.Sleep(sec*1000, True) def SvcDoRun(self): self.ReportServiceStatus(win32service.SERVICE_START_PENDING) try: self.ReportServiceStatus(win32service.SERVICE_RUNNING) #self.log('start') self.start() #self.log('wait') win32event.WaitForSingleObject(self.stop_event, win32event.INFINITE) #self.log('done') except Exception, x: self.log('Exception : %s' % x) self.SvcStop() def SvcStop(self): self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING) #self.log('stopping') self.stop() #self.log('stopped') win32event.SetEvent(self.stop_event) self.ReportServiceStatus(win32service.SERVICE_STOPPED) # to be overridden def start(self): pass # to be overridden def stop(self): pass From timr at probo.com Tue Jul 20 01:08:50 2010 From: timr at probo.com (Tim Roberts) Date: Mon, 19 Jul 2010 16:08:50 -0700 Subject: [python-win32] pywin32 services In-Reply-To: References: <4C44D494.1070506@probo.com> Message-ID: <4C44DB02.1030404@probo.com> Michael Mileusnich wrote: > This is all local to my C drive.

FindFiles returns a tuple of interesting things about the data. The 8th thing in that tuple is the official file name. fname should not be a directory. "fname" should be the full path to the executable. "path" should be the path part of that -- everything up to the last backslash. The join reads the directory to find the full file name, and tacks that on to the path. 99.99% of the time, "fname" should end up the same coming out as it was going in. It would be nice to know whether the "index" it's complaining about is the [0] (meaning FindFiles found no matches) or the [8] (meaning FindFiles returned something unexpected). Perhaps you should add print win32api.FindFiles(fname) and see what it returns. Do you have an extension on your service script? -- Tim Roberts, timr at probo.com Providenza & Boekelheide, Inc.

If I try to > 'start' the service I get my service was unable to respond in a timely > fashion error. Well, wait a minute. How is that possible? How could "fname" get the wrong path? It was fetching the program's name from sys.argv[0], which it should have fetched from the command line that started the service. Did you move the directory after you did the original service creation? Remember that the path to your service is stored in the registry. I hope it's obvious that this path MUST be correct if you plan to have Windows start the service on its own. > Correct my I am wrong but all Windows looks for is the SvcDoRun? No, that's not right. You need to remember the pieces that are involved here. Windows doesn't have any clue about Python. It's just running your service as a standard executable. SvcDoRun is just a Python function, which happens to be called by the PyWin32 service framework. Windows services work by receiving messages from the operating system -- messages that tell the service what to do. There are messages for start, stop, and pause, among others. In response to the "start" message, the Python framework will eventually call SvcRun, which then calls your SvcDoRun. Just because Python makes it easy, that doesn't change the way services work. The registry must be correct, and your service must operate like a normal executable. -- Tim Roberts, timr at probo.com Providenza & Boekelheide, Inc.

In general, using a 32 bit Python + PyWin32 works just fine on 64 bit Windows. However there are a couple of very specific things that require a 64 bit build of Python and PyWin32 (and any other extensions) when running on a 64 bit server. One is running an ISAPI web server extension like iis_wsgi. (Running iis_wsgi may also require a tweak to Python 2.6.5's extension compiling file to fix the inclusion of Visual C runtime in the DLL manifest, but that's a bug/issue in Python, not PyWin32.) The other (I'm not 100% certain about this) is writing a Windows Explorer extension in Python. There may be a few other odds and ends like that which require 64 bit, but if you don't use / need those features, then you don't need to have 64 bit Python. I haven't seen any problems resulting from 64 bit deployment. It works great for me. Hope this helps, Preston -------------- next part -------------- An HTML attachment was scrubbed...

The Active Scripting implementation should register so that inproc or out of proc instances can be created (which is the default for all pywin32 implemented COM objects). By default, most things which consume script engines (eg, IE, IIS) create inproc engines. Hence, a single OS process which creates multiple script engines is sharing the same Python interpreter between instances. Py_NewInterpreter is not used by pywin32's COM support. This means a single OS process using multiple scripting engines will have each engine instance sharing the same Python 'environment' (ie, sys.path, loaded modules, etc). If you have control over the host and really want the isolated behaviour, you could try explicitly requesting an out of proc engine when calling CoCreateInstance.

In the future we'd like to use Python for new projects all together (outside of classic asp). For now we're still stuck with the classic asp environment.

It might set up a message queue, but in order to run an event loop and cause window messages to be dispatched, you have to call app.MainLoop(). Is this a GUI component? It's difficult for me to tell. If it is a GUI component, then you can't just instantiate it in empty space. You have to host it inside some GUI application. I see that it is a socket-based component. If they are using asynchronous socket processing, that also requires that the event loop be actively dispatching. If this expects to be part of a GUI application, then you are going to need to write a GUI application for it. -- Tim Roberts, timr at probo.com Providenza & Boekelheide, Inc.

Yeah, unfortunately, I can't get far enough to call app.MainLoop() -- that wx.activex.ActiveXWindows(f, clsid) line crashes python.exe. > Is this a GUI component? That's what's annoying -- it shouldn't be (the API is data-driven, it doesn't expose any UI controls), but it looks like it's been written as an ActiveX GUI component anyway. (I think the target audience for the ActiveX component is VB developers, so the developer use case they're targeting is "drag tws.ocx onto your form".) They provide C++ and Java socket-oriented interfaces as well, so I'll have a play around with those instead. Thanks for confirming my suspicions. Regards, Trent.

Message-ID: <1280176307.6527.1386838237@webmail.messagingengine.com> Is it possible to update an exe file's properties and/or icon file via the win32api library? By exe file properties I mean the properties typically set via a resource file when an exe file is created. Example properties are what one would see if they right clicked on a file in Windows Explorer and chose the Properties dialog. Sample exe file properties: - product name - product version - product description - copyright - exe icon Use case: We have a single exe whose file properties we would like to customize for specific customers. An alternative question would be is there a way to update an exe's file properties using an external resource file? Or would I be better off finding a Windows utility that might allow me to script exe resource file updates?

See, for example, "resource hacker". There are many valid uses for having multiple external resource DLLs. That's the way internationalization is often done. You have one resource-only DLL for each language, and the main program looks up resources there first. But if you want to change what Windows Explorer shows, then you have little choice other than modifying the executable file itself. -- Tim Roberts, timr at probo.com Providenza & Boekelheide, Inc.

Kinda - although it is pretty painful to use. To get started, check out the 'verstamp.py' utility included with pywin32 and if you want to update the icon etc, be prepared to read the win32 docs for BeginUpdateResource etc and alot of experimentation (although digging into the py2exe source code might be helpful there as it updates icons and string resources using the same basic functions - although not via pywin32) Cheers, Mark From vernondcole at gmail.com Sat Jul 31 09:46:26 2010 From: vernondcole at gmail.com (Vernon Cole) Date: Sat, 31 Jul 2010 01:46:26 -0600 Subject: [python-win32] Announcing adodbapi version 2.4.0 -- now with COLUMN NAME data access Message-ID: Announcing a new version of adodbapi... [ for those who may not know... [ adodbapi is a pure Python package which fully implements the PEP-249 db-api [ using Microsoft ADO/db. [ It runs on CPython versions 2.3 and later, IronPython 2.6 and later, [ or Python 3.0 and later. http://sourceforge.net/projects/adodbapi I have often been frustrated by the need to count '?' marks for input parameters and remembering column numbers to get my SQL output. This release fixes that by allowing the use of 'named' parameters as an option, and by returning 'SQLrow' objects which allow the use of column names. This version includes a distutils setup.py file, so installation is easy. Just 1) unzip 2) "cd" to the directory you just unzipped. 2) Execute the command: python setup.py install using the python distribution of your choice. It even runs 2to3 automatically if you run it using a 3.n Python. (Why didn't I do this years ago?) NOTE: you must have already installed pywin32. This will upgrade your existing version. Here's what's new............................ * adodbapi version 2.4.0 -- in this version, "fetchall()" and "fetchmany()" return an SQLrows object ...which emulates a sequence of SQLrow objects. "fetchone()" or the cursor's "next()" method return an SQLrow object. An SQLrow object emulates a tuple of data fields. An SQLrow object also appears to have an attribute for each column of data. therefore... >>> import adodbapi >>> myConnection = adodbapi.connection('someDSN') >>> cur = myConnection.cursor() >>> cur.execute("select name, rank, serialNumber from soldiers") >>> row = cur.fetchone() >>> assert row[0] == row['name'] >>> assert row[1] == row.rank >>> rows = cur.fecthall() >>> assert rows[4,'serialNumber'] == rows[4][2] * adodbapi version 2.3.0 -- this is includes major refactoring and specifically adds features for django support, including the ability for the programmer to change ado's SQL "paramstyle" at run time to select between 'qmark', 'format' and 'named' methods of passing SQL parameters. ** also, in response to user requests, adodbapi will now use client-side cursors by default. This will make rowcount and stored procedure return parameter values more readily available. -------------- next part -------------- An HTML attachment was scrubbed... URL:
