I afraid no.

Still no and no :-(

REALobject contains INISDE (where and how is closed info) our structure

struct DatabaseData
{
    ulong                    hack; // for RB 2005
    FBL::I_Database*        mpFblDatabase;
    VSQL::I_SqlDatabase_Ptr    mpSqlDatabase;
    bool                    mLocal;
    I_Encryptable*            mpEncryptable;
};    


Even if assume, that we make in V4RB additional methods like

    Vdatabase.GetRef() as Integer

To return you right into RB the raw value of FBL::I_Database*
Still not solved, because V4CC is also ADK and it also have
wrapper-structures around engine.

I think this is wrong way ...may be you need switch from REALbasic ?
