How is TRACKER_API defined? You're using ctypes.oledll, which uses the __stdcall calling convention. It's possible your DLL is defined as __cdecl. Try cdll.LoadLibrary instead of oledll.LoadLibrary. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. -- http://mail.python.org/mailman/listinfo/python-list
