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: * S; U* M N- {- p; f7 tName = (WCHAR *) L"Poke";( k$ Y _ k# U2 N A H
) G* p/ R0 [" A2 f5 j* Y3 n) I4 {
hr = m_pDisp->GetIDsOfNames (+ J2 u' Z: I3 h
IID_NULL, // reserved! z6 [6 C1 A) J6 C4 V$ \
&Name, // Array of names to get IDs for + t$ R& n5 I. D; ^/ ?2 U 1, // # of names in the array ) r5 H1 a6 e( m; `* w LOCALE_SYSTEM_DEFAULT, // System locale : W3 Y/ y5 l# \, h: B6 j6 p0 J &pokeID); // Array of IDs to fill on output * ?, a% R& i. j, N2 b7 ^2 A ( C; K% ]* l% |
