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:
+ O5 M/ N0 g5 |1 RName = (WCHAR *) L"Poke";9 {6 A! r# j7 e, Y: T
. q2 q2 U( G, R; R& ^ hr = m_pDisp->GetIDsOfNames (
$ o0 @, ?* D& i IID_NULL, // reserved6 H7 r( o6 Q/ T& S5 j) o
&Name, // Array of names to get IDs for
+ W" x. \+ K1 A+ b5 w+ P 1, // # of names in the array. B: y# G& z+ c. {/ \6 t
LOCALE_SYSTEM_DEFAULT, // System locale5 R0 @' v3 K0 T5 L- ?
&pokeID); // Array of IDs to fill on output
' n- M( H G, }' u 1 n S3 h. f0 H# \; p* T, V; t
if (hr)
' S3 X b. p8 H% d. r) e0 } {

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???) ^7 u; T9 l8 a. F
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????

请问该程序是获得extend里面的哪个值?
