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());
}

As long as you have a ScriptScope per thread, you should be able to
share the ScriptEngine & Runtime between threads.
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.
