Subject: [Python.NET] How to use python object from powershell drectly?
Message-ID: <CADtvxC84u4pfYqA2cXwh4r1Z32Lo57OCidGYBi7-p5dos9WeMQ@mail.gmail.com>

Hi,

I'd like to call python method, or receive python object (method) directly
from powershell. Is it possible using python.net?

Thanks,
Spark.

In order to test if it is possible, I try to load assembly
Python.Runtime.dll from Powershell.
Once open powershell prompt, and tried to load Python.Runtime.dll, but I
got following error in Windows 2008 R2 x64.

I compiled pythonnet with 32bit and Pyton 2.7.3 (32bit) installed.
(nPython.exe works fine in dos propmpt though, copied nPython.exe,
Python.Runtime.dll, clr.pyd into C:\Python27).
Is there something I missed? or anything I need to check? looks like I need
to load some assemblies before Python.Runtime.dll, or environment settings
to load Python 2.7.3.

Thank you,
Spark.

What exactly are you trying to do?  It looks like you are trying to create a class in python that inherits from .net's System.Object, rather than python's object.  But then you treat it as a dynamic object, which it really isn't.  And then you try and treat it as a statically typed object, which it doesn't seem t be either really, now that you've treated it as dynamic in python.  What is the intent?  Do you mean to create a dynamic object that both .net and python treat as a dynamically typed object?

Actually i'm just trying to use a .net System.Object List with this one -
http://objectlistview.sourceforge.net/cs/index.html. I like the way the
grid is displayed on that objectlistview so i'm trying to experiment and
dispay, but what i get is just an empty row.

Here is the snippet of my code.

def LoadRecord(self,sender,e):
listing = List[person]()
listing.Add(person('jojo','maquiling'))
listing.Add(person('gary','granada'))
self._objectListView1.SetObjects(listing)


A datagrid is good,I have used it, but then i just want to figure out also
if its possible for me to use this ObjectListView control on my application.

Thanks and best regards.

Message-ID: <1369339944.23724.YahooMailNeo@web142606.mail.bf1.yahoo.com>

Brian,


Just wanted to share something with you in case it helps the cause. I was having real trouble getting a custom assembly compiled against 4.0 framework to import. Technically, it was the open source EPPlus.dll library and I could add it fine via clr.AddReference("EPPlus") but the import step failed saying "No module named OfficeOpenXml".

Here's where it gets strange ... the *exact* same source code against the *exact* same target framework 4.0 created slightly different .dll's when compiled from VS2010 vs 2012. The one compiled using Vs2010 had no problems being imported into python.net but the Vs2012 exhibited the behavior above.

It turns out that there's a subtle thing going on:

1) Your ScanAssembly() method inside assemblymanager.cs iterates over all the types in the assembly to deduce namespaces and adds them to a new dictionary object (ok so far)

2) But the 2012-compiled ,dll and the 2010-compiled .dll seem to have their assembly.GetTypes() in slightly different order and your extra "if (t.IsGenericTypeDefinition) {GenericUtil.Register(t);}" piece of this?ScanAssembly() method was running into some generic types w/o a namespace in the 2012-compiled .dll "sooner" than they're listed in the 2010-compiled .dll and blowing things up before any namespaces could be added

To make a long story short, here's what I changed and then all worked again for me:

BEFORE:
if (t.IsGenericTypeDefinition) {
? ?GenericUtil.Register(t);
}


AFTER:
if (ns != null && t.IsGenericTypeDefinition) {
? ?GenericUtil.Register(t);
}

By the way, I was able to compile a new "Python.Runtime.dll" and "clr.pyd" (aka, clrmodule.dll) against 4.5 using Visual Studio 2012 without any problems and load in said EPPLus.dll compiled against 4.5 within my python script. I'm not sure how robust your module is against a heavy RAM/CPU/IO load, but it's definitely intriguing to be able to tap into .NET 4.0/4.5 assemblies from python!!

Cheers,
Tom

Subject: [Python.NET] missing constructor
Message-ID: <519FCC39.5030503@routeware.dk>


First of all, thank you for a great library.

I have run into an issue of an "object" in my assembly that do not have 
a constructor (other than "void").
The object is called TFloatPoint and has 2 public fields x and y.

At first we used this:
myPoint = TFloatPoint(), but that didn't work due to lack of matching 
constructor.

Then I replaced it with a method call that returned a TFloatPoint result 
and that works.

But for another class, I do not currently have any methods returning 
such an instance.

Is there any generally working method, other than creating dummy methods 
returning the desired class / type?

I'm using this one with Python 2.7.2:
pythonnet-2.0-Beta0-clr4.0_140_py27_UCS2_x86.zip

Kind regards
Uffe Kousgaard

Ok Thanks Brad for  the reply.

I'm just confused really on that static and dynamic thing that i have
experimented on it via console. I have figure it out now on how to use that
objectlistview. I've just created a datatable and fill data on it and use
the DataListView which is part of the ObjectListView library.

Python dot net is really a great software.
