8. 如何自定义消息
.h中
#define WM_DO_MESSAGE WM_USER+100

//{{AFX_MSG(...)
    ......
    //}}AFX_MSG
    afx_msg LRESULT OnDoMessage(WPARAM wParam,LPARAM lParam);
         ......
    DECLARE_MESSAGE_MAP()


.cpp中
BEGIN_MESSAGE_MAP(...)
    //{{AFX_MSG_MAP(...)
    ......
    //}}AFX_MSG_MAP
    // Global help commands
    ON_MESSAGE(WM_DO_MESSAGE,OnDoMessage)
         ......
END_MESSAGE_MAP()

LRESULT CTest8Dlg::OnDoMessage(WPARAM wParam,LPARAM lParam) 
{
                  .....你的操作；//如int k=(int)wParam;等等
        return 0L;
}
