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：- C: v# |0 |1 M4 P, H4 }( v+ L
Name = (WCHAR *) L"Poke";
' k; ^7 d* W! {/ g ' s4 }' `2 M5 Y! Q1 K+ t' X

&Name, // Array of names to get IDs for
& r/ ?# a4 _: \9 g 1, // # of names in the array5 S3 ~9 X+ _4 n+ K4 P c3 A& `. v
LOCALE_SYSTEM_DEFAULT, // System locale1 U# |/ O1 u' \% T
&pokeID); // Array of IDs to fill on output

请问该程序是获得extend里面的哪个值？' U& w" Z# s2 ] `
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？？？？ |
