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：
: R+ c$ P: g0 ?2 AName = (WCHAR *) L"Poke";
* g+ u+ @7 ]+ d% h9 B- Q5 U7 q: k T5 g% s+ Q( v- q
hr = m_pDisp->GetIDsOfNames (8 O6 m, _& x7 b6 [) b9 c: S/ ]
IID_NULL, // reserved

1, // # of names in the array
