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：% g' L1 `4 g" _. s# ?
Name = (WCHAR *) L"Poke";& P: Z# U9 x; L
% M2 o: O9 b* p/ _1 P3 }
hr = m_pDisp->GetIDsOfNames (
6 P" _' Z0 O q/ a5 T1 n, p IID_NULL, // reserved
0 x J; m6 M9 ^4 T, ] &Name, // Array of names to get IDs for
9 B( v e0 m; M2 A' P, {6 n 1, // # of names in the array7 `, d0 N* p7 P+ M2 v' \! X) v( H) r* Y
LOCALE_SYSTEM_DEFAULT, // System locale
" w$ o( j9 d8 {2 k; t5 U/ x) _% X5 D &pokeID); // Array of IDs to fill on output

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？？？& r3 V8 Q# m6 O* [6 N
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？？？？
