Directx and Borland C++ Builder

I am trying to compile the "hello world" tutorial of the Direct3d retained version on C++ Builder, but it says that the lpVtbl is not a member of "IDirect..." (this error shows to each one of them used). Everything looks all right, it seems to be declared when the DECLARE_INTERFACE macro (defined in objbase.h) is called.
Just tried now another example (globe.c) and the same thing happened.

The lpVtbl is only used when you use the C interface to the OLE stuff. When using C++ like in C++Builder, the lpVtbl is not used, virtual functions are instead.
I think your problem may be that the example code is in C and not C++. You must coerce the C++ compiler into going into C mode.
