我点击一个按钮，就能得到这个按钮的句柄，不是通过按钮ID得到按钮句柄的,这个我怎么做到？

按钮也是一种mfc窗口,因此,可以子类化按钮控件(也就是产生一个这个按钮控件的映射变量m_myButton),然后在WM_ONLBOTTONDOWN消息重调用 HWND hWnd=m_myButton.GetSafeHwnd();即可得到.

可以呀，成员变量m_hWnd;
最后通过GetSafeHwnd()

[anjy]

CWnd* GetDlgItem( int nID ) const;

void CWnd::GetDlgItem( int nID, HWND* phWnd ) const;

Return Value

A pointer to the given control or child window. If no control with the integer ID given by the nID parameter exists, the value is NULL.

The returned pointer may be temporary and should not be stored for later use.

Parameters

nID

Specifies the identifier of the control or child window to be retrieved.

phWnd

A pointer to a child window.

Remarks

Retrieves a pointer to the specified control or child window in a dialog box or other window. The pointer returned is usually cast to the type of control identified by nID.

可以重新写windowproc，lparam就是hwnd。
