主线程用afxBeginThread()创建多个线程安全退出的办法

HANDLE hand[];
CCriticalSection m_crisecoin;
CEvent m_event;
struct Student
{
    int nNO;
    int nYear;
    CWnd *wnd;
    BOOL bExit;
};
Student stdent;
//创建线程
void CMyDlg::OnBnClickedButtonBegin()
{
    stdent.nNO = ;
    stdent.nYear = ;
    stdent.wnd = this;
    stdent.bExit = FALSE;

    pThread[] = AfxBeginThread( threadADD , &stdent );
    pThread[] = AfxBeginThread( threadADD1 , &stdent );
    hand[] = CreateEvent( NULL,FALSE,FALSE , NULL );//这个是事项
    hand[] = CreateEvent( NULL,FALSE,FALSE , NULL );
}
//线程里面的程序

UINT threadADD( LPVOID  p )
{
    Student *pStudent = ( Student *)p;
    for ( int i = ; i < ; i++ )
    {
        if ( pStudent->bExit )
        {
            SetEvent(hand[]);
            return ;
        }
        ::SendMessage( pStudent->wnd->GetSafeHwnd() , WM_USER_ADD , pStudent->nNO++,  );
        Sleep();
    }
    return ;
}

UINT threadADD1( LPVOID p )
{
    Student *pStudent = ( Student *)p;
    for ( int i = ; i<; i++ )
    {
        if ( pStudent->bExit )
        {
            SetEvent( hand[]);
            return ;
        }
        ::SendMessage( pStudent->wnd->GetSafeHwnd() , WM_USER_ADD1 , (pStudent->nYear)--,);
        Sleep(  );
    }
    return ;
}

退出程序：
BOOL CMyDlg::ExistThread()
{
    m_crisecoin.Lock();
    stdent.bExit = TRUE;
    m_crisecoin.Unlock();
    DWORD dwWait =;
    dwWait = ::WaitForMultipleObjects( , hand , TRUE,INFINITE);
    return TRUE;
}
//挂起线程;
void CMyDlg::OnBnClickedButtonSuperthread()
{
    SuspendThread( pThread[]->m_hThread );
    SuspendThread( pThread[]->m_hThread );
}
//唤起线程
void CMyDlg::OnBnClickedButtonResunme()
{
    ResumeThread( pThread[]->m_hThread );
    ResumeThread( pThread[]->m_hThread );

}
