Hi Alberto - Thanks for your help! Seems to work fine now....except...I am trying to use arrays. I am following the README on the python for .NET website. Here are the commands I am trying to run: from System import Array # works! myarray = Array[int](10) # fails! TypeError: Cannot convert 10 to System.Int32[] I'm a little confused...obviously the example doesn't work, but how *should* arrays be initialized in Python .NET? The c# code might look like: int[,] numbers = new int[,] { {1, 2}, {3, 4}, {5, 6} }; I'm actually looking to make a 2D array. Further, the end goal is to make a 2D array...then serialize it....then deserialize it in c# code itself. I'm hoping to make this a transport layer between Python and C#. It's a bit complicated, but I have an existing application in Python which I want to get some calculated results out of without writing listeners, named pipes, web services, etc. All I want to do is to serialize a .NET 2D array created in Python. - Aaron > -----Original Message----- > From: pythondotnet-bounces(a)python.org > [mailto:pythondotnet-bounces@python.org] On Behalf Of Alberto Berti > Sent: Friday, April 20, 2007 1:49 AM > To: pythondotnet(a)python.org > Subject: Re: [Python.NET] Installing Python for .NET with .NET 2.0? > > > Hi Aaron, > > the tarballs on pythondotnet's site are for .NET 1, if you > want to use it with .NET 2 you should checkout the last svn > trunk and patch it with the instruxtions described in this mail > http://thread.gmane.org/gmane.comp.python.dotnet/576 .In that > message there is also a link to binary packages provided by > Angel Ignacio. > > Hi hope soon to set up a wiki dedicated to pythondotnet as > there aren't so many examples of using it for things like > embedding etc. I'm just looking for a wiki engine which as > some effective spam protection.

Installing Python for .NET with .NET 2.0?
by Aaron Rubin 20 Apr '07

20 Apr '07

Hi - I am running Python 2.4 along with .NET 2.0 I understand that unless I get the trunk of the code, .NET 2.0 is not supported, but I figured it would be backwards compatible? Basically, my problem is the same problem in this posting: I cannot get things to work like the samples on the README on the website. I did, however, try to install in my existing installation of Python, instead of the stand alone. Anyone have the same problems? - Aaron Seshagiri Cherukuri seshagiri.cherukuri at gmail.com <mailto:pythondotnet%40python.org?Subject=%5BPython.NET%5D%20.net%202.0% 20-%20pythonnet%20v2.4%20does%20not%20recognize%20any%20of%0A%09.net%202 .0%20assemblies&In-Reply-To=> Mon Dec 4 21:50:47 CET 2006 * Previous message: [Python.NET] Help please: Convert to Python <http://mail.python.org/pipermail/pythondotnet/2006-December/000564.html > * Next message: [Python.NET] Subset implementation for CompactFramework <http://mail.python.org/pipermail/pythondotnet/2006-December/000566.html > * Messages sorted by: [ date ] <http://mail.python.org/pipermail/pythondotnet/2006-December/date.html#5 65> [ thread ] <http://mail.python.org/pipermail/pythondotnet/2006-December/thread.html #565> [ subject ] <http://mail.python.org/pipermail/pythondotnet/2006-December/subject.htm l#565> [ author ] <http://mail.python.org/pipermail/pythondotnet/2006-December/author.html #565> ________________________________ hi All, I have just installed Pythonnet v2.4 and was trying to work with .net 2.0assemblies, it is not able to recognize any of the .net 2.0 assemblies either those in GAC or those not in GAC. Here are the problems I am seeing ( I am running the standalone pythonnet): 1. The readme files at http://pythonnet.sourceforge.net/readme.html mentions that you dont have to use the CLR.System kind of namespace anymore. However if I write something like from System import String There is an error which says "No module named System" 2. When using .net 2.0 assemblies, even the CLR.xxx syntax is not working - there is always an error which says "No module named xxx" 3. Not able to use any of the .net stuff - e.g. from CLR.System.Collections.Generic does not work because it is not able to see the module Generic. Am I doing something wrong? The 2.4 installation was obtained from here ( http://sourceforge.net/project/showfiles.php?group_id=162464). Do I have to get the latest code instead of these installers to be able to use the .net 2.0 and other features? Looking forward to your reply.

Re: [Python.NET] Unable to import library imaplib

Dear Sir, My name is Vipin, I am a student doing an internship at a small software development company. I want to embed python in C#. But I have no specific idea how to do it. All material that I could find on the net and the books talk about embedding python in c/ c++ using pointers etc. But I want to embed python in a C# code. I read the Python for .NET web page and I think that is something that can fulfil my requiremenmts. But again using pointers in C# is not what we want as it makes us comple 'unsafe' & takes away our garbage collection also. As i am a beginer I would request you to please help me with a 'sample program' that illustrates the entire embedding process. Your help will be deeply appreciated by me. Thanking you, Sincerely, Vipin Gupta Send a FREE SMS to your friend's mobile from Yahoo! Messenger. Get it now at http://in.messenger.yahoo.com/

Hi I changed the version to 2.44, but the problem remains. Meanwhile I found another solution to communicate directly from C# to an IMAP server with a very nice freeware library. It also includes some other protocol communication like pop3, smtp, Auth_HttpDigest, dns, ftp, http, icmp, io, log, mime, nntp, sdp and sip. If you are interested, you can find my writings here http://www.lumisoft.ee/Forum/default.aspx?g=posts&t=98 The example there uses following library http://www.lumisoft.ee/lsWWW/ENG/Products/WEB_Mail/webmail_index_eng.aspx?t… Rregards, Kris Date: Wed, 11 Apr 2007 11:18:24 -0400Subject: Re: [Python.NET] Unable to import library imaplibFrom: brian.lloyd(a)revolution.comTo: kris_beyers(a)hotmail.com; dvpdiner2(a)yahoo.comCC: pythondotnet(a)python.org Note that the latest PythonNet is built for and includes 2.4, not 2.5, unless you’ve built your own version.That probably means that pythonnet is looking at the PYTHONPATH for 2.4, which probably doesn’t have imaplib installed.I’d suggest making sure to install imaplib in the site-packages used by your PythonNet/2.4 installation...-BrianOn 4/11/07 5:16 AM, "Kris Beyers" <kris_beyers(a)hotmail.com> wrote: Hi I can import CLR, but not imaplib.
