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:
M9 L$ F* Y3 ]6 j, r, VName = (WCHAR *) L"Poke";7 b) i5 e/ @9 n8 D# }
# A) W; i5 j+ u- T' N$ a hr = m_pDisp->GetIDsOfNames (8 t5 @8 U5 ^8 d) h+ U
IID_NULL, // reserved
' w! T9 Y8 x/ A% O5 \1 K &Name, // Array of names to get IDs for
. N t) Q% ]% r k$ t& [ 1, // # of names in the array

请问该程序是获得extend里面的哪个值?
% f1 _, |0 w3 Q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???? |
