Marvin,

>I thought so. But it is not nice to distribute an FLL with about 700 kb Size just for this function.

What are you putting in there!? I've done an fll with about 100 lines of code and it's about 20 KB (VC++ 6.0). Did you compile debugging code into the FLL? Just for the purpose of providing a callback function, it shouldn't be more than about 10 KB ...
