I could be mistaken, but I think you are on the wrong list. PythonDotNet is for folks like me who are using CPython and need to interact with .NET managed code. IronPython is NOT CPython. It is Python running inside .NET CLR. I'd recommend going to the IronPython forums or mailing lists for help. --- Matt On Tue, 5 Feb 2008 12:32:54 +0530, Praveen Kumar <praveen@mahiti.org> wrote:
