Question

让我说一下,我是中华的后裔的 w子:

LRESULT CMyEdit::OnPaste(WPARAM wParam, LPARAM lParam)
{
//do some processing
return 0;
}

and let s say that in some cases I want to trigger the default behaviour for paste from this method. How do I do it? CEdit::OnPaste does not exist...

Answer 1

<http://msdn.microsoft.com/en-us/library/3323tewb.aspx” rel=“nofollow”>/code>,通过WM_PASTE,wParam/code>。

典型的情况是,在基数类别中,<代码>OnXxx的操作器包括一条电话<编码>的单行。 DefWindowProc——如果CEdit:OnPaste 存在,它会做些什么。

Answer 2

You can also simply call CWnd::Default. This function, which is defined in wincore.cpp, uses _afxThreadState.GetData() to obtain the information on the message that is currently being processed and then calls CWnd::DefWindowProc.

我提到,如果你在电文地图上使用国家妇女委员会(PASTE)的宏观方法,因而对“OnPaste”功能没有参数,那么Tim Robinson提到的解决办法就不会奏效,因为没有瓦帕拉姆和帕拉姆参数可以传给妇女委员会:DefWindowProc。
