I've tried to compile the original sources from DC++ 0.25 and I ever got 2 Link Errors.
Ok, resolving this problem is much simple
Just Add the ADLSProperties.cpp and ADLSProperties.h in DCPlusPlus Project and enjoy..
I think Arne forgot it before he makes the sources public.
Should be the same at VS6 and VS7 (I'm using).
