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:/ |* q3 x% S+ i+ P2 ^" Z

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???
! C" g6 X' Y8 y" B; @% r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?. i9 w1 q' A% x* \8 J. F1 f
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???? |
