well there are cases (like mine :) where using a DLL would be useful.
Let's say I want to program a CRPG (actually a warcraft clone :)
Now I have the main engine, which gives me the sound, network, input,
graphics, pathfinding etc etc. It would be very useful if I could add a
new character without relinking the whole thing (like if I only
distribute the EXE and the user can add his own guys).
I could have something like a subdirectory with the charater's name and
in that subdirectory, have all the graphics, sounds etc and this little
file called behaviour.dll in which I would have all the functions for
that character. the character is attacked by someone, call a function in
the DLL. the time is 12 and the character set a timer for this hour,
send a message (call a function) to the DLL etc etc.
see what I mean? (of course I could use scripting, which is what I'm
looking at now, but a DLL is compiled code, therefore a lot faster...)
