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:7 E R8 \4 T9 V$ S8 \
Name = (WCHAR *) L"Poke";; f8 k% A9 s! Q% @# {
" M0 l; Q8 v) n8 h( Z0 ]! m; J( Q hr = m_pDisp->GetIDsOfNames (
. K# ^6 f: z5 ~( C0 z; t" ? IID_NULL, // reserved; [3 ^, E4 W( p: b N# h
&Name, // Array of names to get IDs for9 L& c A( m/ u& \, T$ P; Y
1, // # of names in the array
0 ?" _5 M d' g/ @ LOCALE_SYSTEM_DEFAULT, // System locale
5 y9 U: S: z' T* H" O3 Y+ T/ J &pokeID); // Array of IDs to fill on output

请问该程序是获得extend里面的哪个值?/ O3 E- b6 ?6 J
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???? |
