Hi Colin,

I'm not an expert on DLLs, but I have just finished wrapping a BCB component 
into a DLL, to be used in VC++ and BCB.  It took me quiet some time to get 
it right.  The __stdcall is a good calling convention to use, and use 
standard types for parameters (I used ints and enums and it went horribly 
wrong, so changed them to ulong, char, etc).  You also have to make sure 
that the DLL releases memory it creates and vice versa.  Haven't tried 
callbacks though.

Paul.
