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：
+ Z" `2 O+ h! M# t. E+ kName = (WCHAR *) L"Poke";/ X7 M0 u7 w% D& b1 r$ |8 i3 C
$ |3 p8 ]" \1 W3 F* `3 l I- a

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？？？
