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:
" n! C3 W+ [2 D' @) s; R' nName = (WCHAR *) L"Poke";
/ A! f% i( s, O0 ` 6 W0 ~! G: f$ l0 }* W( y4 W% |
hr = m_pDisp->GetIDsOfNames (( s/ E9 u! O/ R: ^
IID_NULL, // reserved

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???
