<br>内容：1.你从CButton派生一个类，然后在OnNotify里写上你的代码！<BR>CWnd::OnNotify<BR>virtual BOOL CWnd::OnNotify( WPARAM wParam, LPARAM lParam, LRESULT* pResult );<BR><BR>Return Value<BR><BR>An application returns nonzero if it processes this message; otherwise 0.<BR><BR>Parameters<BR><BR>wParam<BR><BR>Identifies the control that sends the message if the message is from a control. Otherwise, wParam is 0.<BR><BR>lParam<BR><BR>Pointer to a notification message (NMHDR) structure that contains the notification code and additional information. For some notification messages, this parameter points to a larger structure that has the NMHDR structure as its first member.<BR><BR>pResult<BR><BR>Pointer to an LRESULT variable in which to store the result code if the message is handled.<BR><BR>Remarks<BR><BR>The framework calls this member function to inform the parent window of a control that an event has occurred in the control or that the control requires some kind of information.<BR><BR>OnNotify processes the message map for control notification.<BR><BR>Override this member function in your derived class to handle the WM_NOTIFY message. An override will not process the message map unless the base class OnNotify is called.<BR><BR>For more information on the WM_NOTIFY message, see Technical Note 61 (TN061), ON_NOTIFY and WM_NOTIFY messages. You may also be interested the related topics described in TN060, The New Windows Common Controls, and TN062, Message Reflection for Windows Controls.<BR><BR>
