我现在用c++编写了一个程序，希望能够和extend交换数据，以及自动对extend进行一些操作。我参阅了例子里的关于OLE AUTOMATION方面的c++程序，但搞得不是很懂。比如说，c++程序向extend发送一个数据：
4 `, @' S0 S! z$ z, M* X' {Name = (WCHAR *) L"Poke";0 _# l/ w$ I# L1 Q! p8 w" b
; Q# o h" Y7 C+ T& v$ h" o, d0 t: Y2 D
hr = m_pDisp->GetIDsOfNames (
2 [% \" {" }' ^( @ IID_NULL, // reserved
0 n) @: h* M/ n$ S7 L( E. t* _3 }; y &Name, // Array of names to get IDs for
1 q8 g2 R( z8 O4 R* Y+ O 1, // # of names in the array
, A3 q: I5 \( P. X LOCALE_SYSTEM_DEFAULT, // System locale
; B5 [- |) n5 E" n% U3 l' ^# b &pokeID); // Array of IDs to fill on output
$ W# {% n4 z& D. V6 `& D: M8 Q
