Is there some way of simply overriding methods in Python so that they do get

In Form1.cs I have:
namespace ip_cl1
{
public partial class Form1 : Form
{
public Form1()

My *impression* was that adding stuff to the GAC was a recipe for DLL hell and therefore it was better left to individual users rather than being automatic on installation. This opinion may be ill-informed however... You just have to be *really* careful with you assembly versions, and what kinds of changes cause a rev of version numbers. However, I don't think it should be the default, but it would be nice to have the option during installation. I think gacutil is only included in the SDK anyway. Right. I think the issue of version numbering is tricky, which is why I'm nervous about IronPython being GAC'd. As an example, the IronPython 2.0.1 and 2.0 assemblies have the same version numbers - and I understand why and don't disagree with this decision - but the net result is that Resolver One required 2.0.1 and would probably fail if the user has 2.0 in the GAC. I certainly wouldn't object to it being an installer option, but it would still make me nervous... :-) Having minor IronPython versions have new assembly versions would probably help - but with the disadvantage that they are no longer drop-in replacements.

Re: [IronPython] Question Regarding WPF : DataBinding, DataTemplates and C# Extensions
As the error message says, it cannot find the type LocalTimes.
Normally you have to map an xml namespace into the corresponding clr
namespace by adding something along the lines of
xmlns:src=clr-namespace:Whatever.Namespace;assembly=TheAssemblyName
to the xaml file
and then you would declare the objectDataProvider like this instead
ObjectDataProvider x:Key=localTimes ObjectType={x:Type
src:LocalTimes}/
However, I'm not sure how it works if you don't put LocalTimes in a
namespace

*Subject:* [IronPython] Question Regarding WPF : DataBinding,
DataTemplates and C# Extensions
Dear Group,
I have a rather involved question (more accurately series of questions)
regarding WPF, particularly how it relates to DataBinding and
DataTemplates. I will do my best to keep this posting to a reasonable
length, but ... well ... I guess this serves somewhat as a warning ;) If
you will spare me a bit of background, I recently began trying to learn
IronPython after hearing an enthusiastic endorsement from a friend and
colleague. While not a programmer or computer scientist by training (on the
opposite of the spectrum, actually, my degree is in biomedical engineering);
I have found myself increasing needing to work with programming tools in the
past few years. This friend pointed me toward the .Net framework, and
IronPython in particular as a potential solution to several major issues we
have been facing with our primary data processing tool: Matlab.
As a trial test, I therefore decided to create a small program in
IronPython, namely, a Podcast Aggregator. I purchased a Manning Early
Access Program copy of Michael Foord's (excellent BTW) book, IronPython in
Action and started trying to work toward my small test project. As I also
wanted to learn WPF (not to mention make my little program as pretty as
possible), I decided to write the user interface for my aggregator in .xaml.
So, with that background out of the way, I arrive at a few questions. The
first of these is somewhat of a follow-up to a topic addressed in May on
this very list somewhat recently (reference:
http://lists.ironpython.com/pipermail/users-ironpython.com/2007-May/004912.html).
In the original post, the author (Bish Bosh) asked what the best method of
referring to Python types in Xaml was. Later in the discussion, Dino
Viehland offered that it might be best to:
Declare an interface in C# (or find an existing one which has what you
want) and inherit and implement the interfaces in Python. Then the
interface will be the bridge between the static and dynamic worlds
(reference:
http://lists.ironpython.com/pipermail/users-ironpython.com/2007-May/004913.html
).
So, my first question: After reading all the material I have been able to
find on the subject, I have not been able to locate a good tutorial or
example of how this might be done. Might it be possible to get some
additional information on how this can be accomplished? A simple example of
how it can then be integrated into IronPython code would be extremely
appreciated.
I have made an effort using the information available in the IronPython
tutorial and a relatively simple XAML example (reference:
http://blah.winsmarts.com/2007-3-WPF__The_DataTemplate,_choosing_how_your_data_will_look_like.aspx),
but I have had no luck in creating a test application that will successfully
load and perform as advertised.
Using the xaml, C# and mainWindow.py file below, I receive the error:
SystemError: Type reference cannot find public type named 'LocalTimes'
I am at the end of my rope and am not sure what I should try next. Are
there any ideas on how I might successfully implement a custom C# interface?
Sincerely,
Rob Oakes
PS, Here is the source code for the simple test case I have been working
with.

But your program almost certainly makes use of parts of the standard CPython library, which you'd then have to copy over as well.

Re: [IronPython] C#, Types and IronPython
Several of the MSDN examples use 'typeof(int)', why not just specify 'Int32' ? I guess it makes the code less platform dependent ?? Oh well. they are not the same thing In CLS (or whatever the .net type system is called), System.Int32 is the normal integer type, that you can type just int in C# is just syntactic sugar. In normal cases you work with variables, but in some cases you want to work with the types (just as you can use e.g. type(42) in python), in that case you can use either typeof(int) or int foo=42;foo.GetType() (or Type.GetType (System.Int32) ) and of these the former is more efficient if the type you want is known at compile time.. hope this helps, Simon ___ users mailing list users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com
Re: [IronPython] Method invocation when assigned to instancediffers from default assignment?
snip -Original Message- Here's a simple scenario I can think of where instances might have callable attributes that don't need (or want) self automatically put in as the first argument: --Reply-- But see, wouldn't it be nice, in your example, to do this: import sys class Logger(object) : writer = sys.stdout.write def __init__(self, writer=None) : if writer is not None : self.writer = writer def Log(self, message) : self.writer(message) Temp = Logger() OtherTemp = Logger() ErrorLog = Logger(sys.stderr.write) #At a later point in time... messageCount = 0 def myLogger(message): global messageCount messageCount += 1 sys.stdout.write( + str(messageCount) + + message) Logger.writer = myLogger Temp.Log(SomeMessage) OtherTemp.Log(SomeMessage) ErrorLog.Log(SomeError) As neither Temp nor TempOther have their own instanced function, Log would have to fallback on the class function, which is now different, just like any other class variable. But we can't do that as a function attached to a class is considered an unbound method. This inconsistency is what has me confused about the utility of this ability. FWIW, if you want to add a new instance method to an already instantiated class, in python you can do import new Temp.writer = new.instancemethod(myLogger, Temp, Logger) (Haven't tried it IronPython though..) ___ users mailing list users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com

Is a better diagnostic message
possible? This would let us distinguish a pyd problem from playing
tricks with paths, and presumably there might be some value in fixing any

You're right, I did miss
that… Looking at this page: http://pyxml.sourceforge.net/topics/howto/section-install.html
It would seem that you may be right about the Pyd's (it at least requires
a C compiler, making that likely – and almost guaranteeing it won't
work w/ IronPython).
Unfortunately we don't support
PYD's currently (and aren't likely to soon) so most likely this
won't currently work. If you absolutely need XPath support in the mean
time I'd suggest using .NET's XMLPath (and if you need to work on
both you could make a thin wrapper over either PyXml for CPython and
.NET's XPath support). For example:
import clr
clr.AddReference('System.Xml')
import System.Xml.XPath as XPath
xpathDoc =
XPath.XPathDocument('file://foo.txt')
