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：6 s" Y) {& p1 E4 |+ w' M+ ?
Name = (WCHAR *) L"Poke";
1 k) R! y0 e: R1 G; d( m6 L
8 J5 N3 q+ I+ `; P! h% q3 s hr = m_pDisp->GetIDsOfNames (

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？？？
% c8 `, X4 k+ E* R/ k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？？？？
