Lalit, If your C++ dll is a plain (unmanaged, machine-code) dll, you probably want to take a look at ctypes:
http://starship.python.net/crew/theller/ctypes/ Python for .NET doesn't specifically help you use arbitrary unmanaged dlls (but you should have no problem using ctypes within Python for .NET). -Brian On 4/4/06, Lalit DIGARI <[EMAIL PROTECTED]> wrote: > Thanks mark, > How could I use dll's exposed function with in python script? > Reagrd's > lalit > > -----Original Message----- > From: Mark McMahon [mailto:[EMAIL PROTECTED] > Sent: Monday, April 03, 2006 5:41 PM > To: Lalit DIGARI; pythondotnet@python.org > Subject: RE: [Python.NET] Use of c++ dll in python > > > Hi Lalit, > > This is not really the group to ask this question - as it doesn't have > anything to do with python.NET. > > But other then that I can answer your question I think :-) > > You say a "C++ DLL".
