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：
& K# r- x) ~, s) hName = (WCHAR *) L"Poke";, @( i" }1 Q: q1 H
- n$ }( e1 }, O4 Q& ^9 I% Y
hr = m_pDisp->GetIDsOfNames (0 s/ ^7 ^1 ?6 L2 V2 m3 w2 P
IID_NULL, // reserved7 L" `) v7 Q5 Q3 k
