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：0 f5 n& ?* L' I x3 y* V/ b
Name = (WCHAR *) L"Poke";
# C( H6 h4 W) B+ C: w* f ]
& ^8 R1 M0 ?: k' O0 C hr = m_pDisp->GetIDsOfNames (
0 l2 V& g t8 A8 v IID_NULL, // reserved
/ H! g; n( Q) e& e &Name, // Array of names to get IDs for/ h$ B. `' }/ j e# G
1, // # of names in the array- A; g7 ~6 p9 S0 C8 `- |/ \; ] ~
LOCALE_SYSTEM_DEFAULT, // System locale* g4 ?8 f0 c! }( z1 r
&pokeID); // Array of IDs to fill on output
: |. N! ^4 n- @) u) { - Y( n5 J% w0 V l8 w, G
if (hr)

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？？？& s6 m/ |% A6 b+ w* Q/ 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？？？？
