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:8 @" X& W u1 Z( V2 }, `
Name = (WCHAR *) L"Poke";1 x! p) L9 c, Y" t% b9 t: D
! Y& W$ j6 e- Q. J' G' L7 H

IID_NULL, // reserved! t5 M8 C- w/ G/ ?, \( M
&Name, // Array of names to get IDs for3 }. {! K3 w) c
1, // # of names in the array

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???

请问该程序是获得extend里面的哪个值?
/ n: c1 G6 g) w5 _- t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???? |
