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：' D/ d" L7 ^3 J* V
Name = (WCHAR *) L"Poke";
/ Z3 w/ f2 h3 v4 P $ y% L4 _8 c& l: C. ?+ N2 k7 l* b
hr = m_pDisp->GetIDsOfNames (+ Y" x* o0 x- t* i) m
IID_NULL, // reserved
+ H1 \* A. J+ k0 l7 ^) ] &Name, // Array of names to get IDs for
3 J/ U2 i5 z, A+ x# `( N& u# h 1, // # of names in the array
( b: e/ E7 Z/ t B3 [& w- j LOCALE_SYSTEM_DEFAULT, // System locale

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？？？
