by Sharon Rozenblum 5 এপ্রিল, 2013

Hi! Can someone tell me how to set PYTHONPATH variable in code when working with Python.Runtime.dll without changing the value in the system variables before.

Better doc strings.
by Brad Byrd 25 এপ্রিল, 2011

25 এপ্রিল, 2011

I'm trying to provide better documentation for some C# classes that are called from Python. Ideally, I'd like to markup my class in C#, either with the standard XML comments or with something like a [PythonDocAttribute], and have this documentation show up as the __doc__ string for the method or class in Python. That way, the clients of my wrapped objects will see nice tool-tips on my classes as they code away in their IDE. So, is this easily done? Has anyone else crossed this bridge before? Does something already exist that would work before I start hacking on the Python.NET source? (Also, are the archives of the list searchable somewhere? I just saw clickable-by-month archives, not searchable.) Thanks, Brad...

PyTables working with python not working with python.net
by Guillaume Pichard 2 এপ্রিল, 2011

2 এপ্রিল, 2011

Hello, I am trying to use pytables with python.net. It is working great with python alone. What I am doing with python.net is: PythonEngine.Initialize(); PythonEngine.AcquireLock(); PyObject sys = PythonEngine.ImportModule("sys"); PyObject path = sys.GetAttr("path"); PyObject append = path.GetAttr("append"); PyObject[] a = new PyObject[1]; a[0] = new PyString("C:\\Python27\\Lib\\site-packages"); append.Invoke(a); PyObject pyTables = PythonEngine.ImportModule("tables"); if (pyTables == null) throw new PythonException(); The exception message is "ImportError : DLL load failed: Specified module not found." What could be the differences between python.net and python ? Is there any specific path to add ? Thanks a lot, Guillaume.

Pre-method and post-method call hooks?
by Brad Byrd 28 মার্চ, 2011

28 মার্চ, 2011

Other than just modifying the source (in methodbinding.cs?) and doing it myself, is there an easy way to globally hook methods so that I can do something immediately before and after a method invocation from Python? For example, I'd like to acquire/release a lock or check if some subsystem is started up, and I'd be a lot cleaner to do it in one place instead of at the top/bottom of every single public function that I expose to Python. Thanks, Brad...

Application shutdown when Py_Initialize()
by Guillaume Pichard 25 মার্চ, 2011

25 মার্চ, 2011

Hello, I'm trying to get python.net work in c#. But I'm stuck at the first step which is to initialize python. When calling Py_initialize() my application shutdown without warning or throwing exception. I'm using python.net for python 2.7, I have installed python 2.7 and added python to path environment variable. What do I do wrong ? Thanks.

Working with XAML and WPF
by Victor Demydov 19 মার্চ, 2011

19 মার্চ, 2011

Hello, Has anyone been trying to use PythonNET to drive a WPF-based application? I am hitting a wall at first step - parsing my XAML with XamlReader. It is failing with a message indicative of bad Xaml, but it is fine (runs in IronPython). Google is proving futile after few hours of searching... any help would be greatly appreciated! Sample Code: # Reference the WPF assemblies import clr clr.AddReference("PresentationFramework.Classic, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35") clr.AddReference("PresentationCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35") import System.Windows Application = System.Windows.Application from System.Windows.Markup import XamlReader class XamlLoader(object): def __init__(self, xmlData): self.Root = XamlReader.Parse( xmlData ) def __getattr__(self, item): return self.Root.FindName(item) print "begin run" xamldata = """ <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="WpfApplication3" Height="300" Width="300"> <Grid></Grid> </Window> """ print xamldata xaml = XamlLoader( xamldata ) my_app = Application() my_app.Run(xaml.Root) print "ending run"

Pythonnet for Python2.7 binary distribution?
by Olof Bjarnason 7 মার্চ, 2011

7 মার্চ, 2011

Hi Python.NET (is that the correct spelling..?) community! I learned of Python.NET today. I love the idea of being able to use the .NET assemblies/types directly from CPython. I've tried IronPython before, but it just does not feel Python enough for me :) But I failed to play with Python.NET tonight, since I'm at a CPython2.7 computer. I couldn't find a 2.7 port of Python.NET on SF, even though I found a note about the changes necessary already being available: http://sourceforge.net/tracker/?func=detail&aid=3094895&group_id=162464&ati… /Olof PS. I'd love to help somehow with this project, since my day-time work is with a C# program, and I'm trying to integrate Python into "the loop" more and more. DS
