That's quite easy:
Declare each function that you want to use in VB as (e.g.)
extern "C" int ___declspec( dllexport) MyFunction ( int i);
In VB, use
Declare Function _MyFunction lib "mydll.dll" (inp As integer) As integer
(NOTE the '_' before MyFunction - most C linkers prepend the functions' names with it if you don't suppress this explicitly)
