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:, `9 z& [9 m1 y3 w" c4 e/ A
Name = (WCHAR *) L"Poke";
0 ^" d' k/ }* n/ w, D3 n/ R% k3 n
7 x6 s, ^0 O/ Y% f d# z hr = m_pDisp->GetIDsOfNames (
# j# f& I# Z. S- A* e3 E IID_NULL, // reserved
6 S) E2 p* H/ H( z, `' p1 W &Name, // Array of names to get IDs for! _% I- s+ o) e1 H( H( p
1, // # of names in the array

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???
