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：" N0 j: n7 }% s$ P4 t3 C4 V( p- K J
Name = (WCHAR *) L"Poke";( V/ f4 T9 Q7 |# I! e
* U* G, Y: @1 E6 O! |; l( ^ hr = m_pDisp->GetIDsOfNames (
& S7 g N% I. v IID_NULL, // reserved

: n7 Y# G: _. v( j 1, // # of names in the array
% p, S' L5 x2 Q$ X% ^3 w: J1 [9 F LOCALE_SYSTEM_DEFAULT, // System locale

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？？？- u+ f D# a7 i0 C! x$ f7 B
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？？？？
