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：
# k8 {8 Z" X! n% _1 Q( p5 N. fName = (WCHAR *) L"Poke";4 q0 }& ~3 L4 S: E0 S" N Q9 W
% g. \7 f: L. T: c3 Q hr = m_pDisp->GetIDsOfNames (
8 E; ^ f2 ?" f( p IID_NULL, // reserved
# v& `2 A- c" B &Name, // Array of names to get IDs for1 m7 A! ~9 j+ @ d) }; j: d) D1 A+ y: z
1, // # of names in the array
2 ~, E6 F% X" D! g y2 p LOCALE_SYSTEM_DEFAULT, // System locale' Y' z+ _2 e; ^, V& W4 `" V% g
&pokeID); // Array of IDs to fill on output, B' m4 o2 S9 f
9 g6 N- O+ _2 b/ }! ]
if (hr)
# M6 a8 y+ @; O5 P, y" O$ V {: B3 `$ L- \9 t1 Z) h
MessageBox ("Get Poke Unsuccessful");0 L' O4 g( J* ~1 \& E) A$ }% _
return;
