p->m_pTheadA=NULL;
}

return 0;
}
void CBase::StartThreadA()

{
if(!TerminateThread(m_pThreadA->m_hThread,0UL))

delete m_pThreadA;
m_pThreadA=NULL;
}
m_pThreadA= AfxBeginThread(ThreadA,this,THREAD_PRIORITY_IDLE,0,0,NULL);

Answer 1

在一个view中
BOOL CXXView::PreTranslateMessage(MSG* pMsg) 
{
// TODO: Add your specialized code here and/or call the base class if(pMsg->message==MSG_XXXXX&&m_pBase!=NULL)
{
            .......
            .......
}

return CView::PreTranslateMessage(pMsg);
}

Answer 2

试了啊  sendmessage 感觉好像一点儿用都没有

Answer 3

用PostMessage很不专业，用PostThreadMessage向你的主线程发送消息更专业一些，你的问题也可以得到解决。

Answer 4

点菜单时响应WM_ENTERIDLE消息，这样处理
       BEGIN_MESSAGE_MAP(CMyDlg, CDialog) 
              //{{AFX_MSG_MAP(CMyDlg)
                    ON_WM_ENTERIDLE()
              //}}AFX_MSG_MAP
       END_MESSAGE_MAP()           void CMyDlg::OnEnterIdle(UINT nWhy, CWnd* pWho) 
          {
                  CDialog::OnEnterIdle(nWhy, pWho);
  MSG msg;
  if (PeekMessage(&msg, m_hWnd, MSG_XXXXX, MSG_XXXXX,PM_REMOVE))
                  {
                       .......
                       .......                  }          }
