Hi, I know this is not exactly a new question on this list but I have not been able to solve my problems by reading old threads. I have a dll (MyDLL) from which I want to call some methods. I've tried using Ctypes: print windll.MyDLL.FirstMethod() print windll.MyDLL.SecondMethod() If I run this, SecondMethod fails, but if I switch order FirstMethod will fail instead (since it is the second called...). The same dll can be used without problems in C++ code. So my questions are: 1. Does Ctypes have any "FreeLibrary" function? 2. Have you got any suggestions on alternative ways to call a dll (assuming you haven't got the source code to the dll)? Regards Ola
