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：
1 Q$ E3 C6 U+ t# qName = (WCHAR *) L"Poke";. v: h' x1 c. B- P2 h
3 C3 s4 L* k1 g6 d/ S' s hr = m_pDisp->GetIDsOfNames (4 `' u3 Z- `% A6 Q3 j
IID_NULL, // reserved
4 \) i0 M7 x7 j6 _# C( a+ Z &Name, // Array of names to get IDs for+ ?; y8 }: C6 s7 T; a" P
1, // # of names in the array
8 }0 h' K; U5 v x7 Q LOCALE_SYSTEM_DEFAULT, // System locale
% i3 X7 W4 \6 f7 u1 s1 Y( _1 ]6 o &pokeID); // Array of IDs to fill on output
& X8 s4 a# { j- |4 \7 l9 } . }" C( Z- F8 V$ Q, c
if (hr)! c, k: V4 z: F
{
! |" H9 Q* L5 c, H5 L MessageBox ("Get Poke Unsuccessful");* E( W( C# h2 L2 `) [

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？？？
% R9 h! u a) C! ]* S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？？？？

请问该程序是获得extend里面的哪个值？
