I applied the suggested patch and have been testing it for quite a few days. The exception did not occur ever since. So I think I can assume that the problem is no longer there. Thanks a lot for all your timely help

The fastest possibility is:- Fetch the IronPython source.- Patch PythonContext.GetEqualSite yourself according to the description in the thread.- Use your own compiled version.

April 2011 04:28 An: Discussion of IronPython; Jeff Hardy Betreff: Re: [IronPython] how to generate multiple concurrent scriptignengines? Hi,Sorry I missed the posts on this thread. This is the code that caused me the problem (I posted this in the first post of the thread)So according to your mails, I take that this is due to a bug in the ironpython code. Is there a way I can have some alternative work-out, something that I can do through my code? (i'm in kind of a hury to finish the project :S ) ScriptEngine engine = Python.CreateEngine();ScriptRuntime runtime = engine.Runtime;ScriptScope scope = runtime.CreateScope();ops = engine.Operations;try{ScriptSource source = engine.CreateScriptSourceFromFile("ironpython.py");source.Execute(scope);string class_param = rule;object[] parameters = new object[1];parameters[0] = class_param;object klass = scope.GetVariable("model_checker");object instance = ops.Invoke(klass, parameters);method = ops.GetMember(instance, "check_model");}catch (Exception e){Console.WriteLine(e.ToString());} --- On Thu, 14/4/11, Jeff Hardy <jdha...@gmail.com> wrote: From: Jeff Hardy <jdha...@gmail.com> Subject: Re: [IronPython] how to generate multiple concurrent scriptign engines?

What is the exception that you are getting? If it's a GUI program, remember that UI elements can only be manipulated from the main thread. - Jeff On Thu, Apr 14, 2011 at 1:02 AM, surangika ranathunga <lady_ra...@yahoo.com> wrote: > > Hi, > I am using Ironpython to connect to a legacy python code from C#. > I am not fully familiar with Ironpython, but managed to get it working for a > single-threaded application. > This is how I implemented this: > > ScriptEngine engine = Python.CreateEngine(); > ScriptRuntime runtime = engine.Runtime; > ScriptScope scope = runtime.CreateScope(); > ops = engine.Operations; > ScriptSource source = > engine.CreateScriptSourceFromFile("ironpython.py"); > source.Execute(scope); > string class_param = rule; > object[] parameters = new object[1]; > parameters[0] = class_param; > object klass = scope.GetVariable("model_checker"); > object instance = ops.Invoke(klass, parameters); > method = ops.GetMember(instance, "check_model"); > > Now I want to make my application multi-threaded, and I want to have > concurrently running scripting engines.
