n this case it is only a dll for exchangability reasons. But some layers above a COM-Server will use this dll indirect. > > Have you built your DLL as a DLL or a COM-Object? > Which threading model do you use?

The dll has already been used in some test apps. one of them using 3 concurrent Ethernet connections, communicating a whole night through without any problems. It seems the only problem left with it is the colsing part. > > The biggest question is why you need a DLL?

The dll was thought of a "simple" encapsulation of all communication methods available for my projects. So the communication dll itsself avoid threads as much as possible. > Are you sure that the ONLY problem you have is with the TWSocket.close > and free?
