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：
t$ y) E7 O7 ?- TName = (WCHAR *) L"Poke";' \4 D/ z% i% l6 o! y2 j1 Z
* F# L- o) Z" a( t$ k5 u8 G3 B: O

0 l- |. Y# }! n IID_NULL, // reserved+ ` y; E% X' W" Y$ V
&Name, // Array of names to get IDs for
2 L- b; @% l9 S. ] 1, // # of names in the array
0 `' O+ D. C! h. |% l5 S9 o1 ^ LOCALE_SYSTEM_DEFAULT, // System locale% g- Q+ Y) D6 @$ I* ]
&pokeID); // Array of IDs to fill on output

请问该程序是获得extend里面的哪个值？. K" `6 N! ^. m0 n
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？？？？ |
