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:% o* N8 h- ]- ]+ F7 B
Name = (WCHAR *) L"Poke";- x0 w2 U9 P8 K: ]( g
! z( c" f! V, U hr = m_pDisp->GetIDsOfNames (
2 x! `! W( N3 k IID_NULL, // reserved
f/ R! w8 B+ C; A& } &Name, // Array of names to get IDs for
4 t% o3 ?$ a! b0 W( p+ g 1, // # of names in the array, ]/ \/ D& A; w9 G% @4 ^) G2 ?( h
LOCALE_SYSTEM_DEFAULT, // System locale

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???
, B' ~3 m: W4 d8 }) t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????

请问该程序是获得extend里面的哪个值?
6 \5 {9 V, d) G如果我希望获得extend程序里面的某个变量的数值,那个c++程序应该如何实现???? |
