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：2 D/ |* ^0 l+ J0 U; W
Name = (WCHAR *) L"Poke";
6 c. d3 n2 F m 1 t6 j# X6 G9 h" f& g8 {
hr = m_pDisp->GetIDsOfNames (4 ]$ ~% U1 B+ W5 a( ^9 R; q% k
IID_NULL, // reserved! Z" v# |; s' U! @2 n1 J, E/ u
&Name, // Array of names to get IDs for
9 X$ U! k% u/ y' R9 n 1, // # of names in the array6 i* a3 J! a7 b% v% g5 f/ R
LOCALE_SYSTEM_DEFAULT, // System locale

7 U4 r& `0 D* t- G5 |# a. V1 [

现在这个程序可以实现将1232这个数据发送到extend，extend有一个对话框弹出并出现1232这个数据，不知道这个对话框为什么会弹出并显示这个数据？？？
6 `- I- G, j# Z& u: H此外我希望将这个数据赋给extend程序里面的一个变量，请问如何实现？？？？
