[IronPython] Installing IP with the new CTP
Hi Martin Thank you for your update on the tutorial, good news. I can get by without animations for now - but do you know a solution for the threading problem in the new environment? I can only do more substantial work by running from scripts rather than interactively! It's the eventually deliverable IP/WinFX combination that I'm interested in; so I'd rather have something with shelf life despite the occasional roadblock than revert to an obsolescent configuration of system software - up to a point at least.

Re: [IronPython] Experience installing IP with the new WPF CTP
Did you spell it RepeatBehaviour or RepeatBehavior (shouldn't have the u on this side of the ocean. ;-) Greg Iain Mackay wrote: I ran into several problems running the first Avalon example from the tutorial, using IP 0.9.6 I should mention that at this time I was running .net Framework 2.0 and the Dec 2005 CTP preview of WPF x64 versions without the Framework SDK; installing the SDK subsequently did not change the behaviour. I noticed three problems: - I couldn't set the Text attribute on a Window object - I couldn't set the TextContent attribute on a TextBlock object - the class RepeatBehaviour seems not to be imported. Another strange aspect is that I get this far when I enter the script interactively to the console, but when I put the script in a file and execute it from the command line I get the exception: System.InvalidOperationException: The calling thread must be STA, as many UI components require this. on calling the Show method of the Window object. I think I might need to rebuild the console to sort this out - C# and .net threading models are rather a steep learning curve for this evening, so I've stuck to interactive experiments for now. Here's my console experience following the tutorial: G:\downloads\ironpython\IronPython-0.9.6\IronPython-0.9.6\Tutorialironpytho nconsole IronPython 0.9.6 on .NET 2.0.50727.42 Copyright (c) Microsoft Corporation.

However, if you set Title, all is well. w.Content = TextBlock () w.Content.TextContent = Hello IronPython! Traceback (most recent call last): at shell TypeError: can't set arbitrary attributes on built-in type System.Windows.Contro ls.TextBlock Similarly, w.Content.Text = Hello IronPython, works just fine. You can discover the attributes of w of course just by: for (key, value) in w.__dict__.items (): print key, value (Iron)Python is so cool like that. w.Content.FontSize = 50 a=DoubleAnimation(0.0,Duration(TimeSpan.FromSeconds(3))) a.RepeatBehaviour = RepeatBehaviour.Forever Traceback (most recent call last): at shell NameError: name 'RepeatBehaviour' is not defined ^Z I didn't persist beyond here just yet. I suppose there have been some substantial changes in object properties during the evolution of WPF as seen in this latest preview, not yet reflected in the tutorial source - a life on the bleeding edge thing. import sys sys.path ['G:\\downloads\\ironpython\\IronPython-0.9.6\\IronPython-0.9.6\\Tutorial', 'G:\\downloads\\ironpython\\IronPython-0.9.6\\IronPython-0.9.6\\bin\\Lib'] Anyway, a whole lot of wonderful things are working straight out of the box, including the XAML calculator. This is going to be a lot of fun. Thanks to everyone for getting things this far. Am I doing something silly to get the threading problem?

Re: [IronPython] Installing IP with the new CTP
Hi Iain, The threading issue... It seems that STAThred is what works for most uses so in the next release we are making IronPython STA by default. We are also adding a command line parameter -X:MTA that will run the script / interactive prompt on MTAThread thread. Hope this helps Martin -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Iain Mackay Sent: Wednesday, December 28, 2005 1:49 AM To: users@lists.ironpython.com Subject: [IronPython] Installing IP with the new CTP Hi Martin Thank you for your update on the tutorial, good news.

Re: [IronPython] Bitwise boolean operators and Forms
The DockStyle enum does not have the Flags attribute so
IronPython doesn't add the bitwise operators.

[IronPython] os.mkdir and os.rmdir
I'd like to see os.mkdir and os.rmdir implemented in the next release of IronPython. Until then, this seems to work: import System import os os.mkdir = System.IO.Directory.CreateDirectory os.rmdir = System.IO.Directory.Delete Seo Sanghyeon ___ users mailing list users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com
[IronPython] os.path functions give wrong result on non-Windows platforms
Currently, os.path module is same as ntpath, and gives wrong result on
non-Windows platforms.
IronPython 0.9.6 on .NET 2.0.50727.42
Copyright (c) Microsoft Corporation. All rights reserved.
import os
os.path.join('a', 'b')
'a\\b'
Currently, I have the following code in my site.py, but obviously this
is not the correct solution:
import System
import os
if str(System.Environment.OSVersion.Platform) == 'Unix':
import posixpath
os.path = posixpath
Any idea?
