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：
3 c V6 s8 k E/ {Name = (WCHAR *) L"Poke";
2 m( ^) _# g! y9 r( L ) Y1 L- c' I5 ^0 W
hr = m_pDisp->GetIDsOfNames (
0 P7 D$ f2 t1 B7 G IID_NULL, // reserved y* u. ]6 ?$ g
&Name, // Array of names to get IDs for) x* @7 ^: ?% W! ^
1, // # of names in the array
5 G+ F0 b5 S2 q: A1 @8 X LOCALE_SYSTEM_DEFAULT, // System locale( S% y. E# \# q" A
&pokeID); // Array of IDs to fill on output
, f W! B* A( O4 a

- p4 T6 Z# R# {# e% Z5 W2 J {' ^& H- ]3 n8 K" q

如果我希望获得extend程序里面的某个变量的数值，那个c++程序应该如何实现？？？？ |
