Just to speed up my calculations I wrote a good part of the functions in C++ and imported in Excel as DLL. Now, for practical reasons I would prefer to write them in Visual Basic and than to create a DLL with the VB6 compiler.
How should I proceed?

Function Example:

Function abc (x As Single, y As Single) As Single
abc = x * y
End Function

Should I open an ActiveX DLL or an AddIn? How should I save it?

Thanks to everyone

Filippo
