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：' l. M# H0 P; [ o. n
Name = (WCHAR *) L"Poke";2 [- e" e" h7 `; c
' m' a% ^ t; f6 ^: w
hr = m_pDisp->GetIDsOfNames (/ F# {" Y# C! u: ~4 c
IID_NULL, // reserved
( U7 n8 i% h7 _/ Z &Name, // Array of names to get IDs for( V, }) f& I) B m1 g
1, // # of names in the array
1 d3 ]0 B6 ~# d( M6 _$ @6 H; l LOCALE_SYSTEM_DEFAULT, // System locale) ]4 z5 O+ Q6 Y6 z: c
&pokeID); // Array of IDs to fill on output5 k7 \, z O5 X) q
# h2 @/ ?) j* o* X: g
if (hr)

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？？？& @4 [& U0 b/ \' B
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？？？？( k- I; M- Y' b/ D- l- h
