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：- e+ w' P M6 c7 o8 e2 F
Name = (WCHAR *) L"Poke";
( U- {. e1 o4 \5 d4 u' ^1 M7 ? 5 T4 q; R6 ^& \; T
hr = m_pDisp->GetIDsOfNames (
9 h! ]# ?5 Y3 U) v; @" q! s y( g IID_NULL, // reserved
1 E/ v2 N0 z% ?- P, t& L6 b% u &Name, // Array of names to get IDs for
& B* p: I8 U& w$ y5 w' ?5 `2 ~ 1, // # of names in the array
0 v+ e( C% h' i LOCALE_SYSTEM_DEFAULT, // System locale
6 v4 T& q$ d) j: q7 D! h7 z( H &pokeID); // Array of IDs to fill on output
$ ^- t% W/ D% o9 @" m3 n! M; E' Y
