主线程用afxBeginThread()创建多个线程安全退出的办法

HANDLE hand[2];
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 = 1;
    stdent.nYear = 10000;
    stdent.wnd = this;
    stdent.bExit = FALSE;
    
    pThread[0] = AfxBeginThread( threadADD , &stdent );
    pThread[1] = AfxBeginThread( threadADD1 , &stdent );
    hand[0] = CreateEvent( NULL,FALSE,FALSE , NULL );//这个是事项
    hand[1] = CreateEvent( NULL,FALSE,FALSE , NULL );
}
//线程里面的程序

UINT threadADD( LPVOID  p )
{
    Student *pStudent = ( Student *)p;
    for ( int i = 0; i < 9999999; i++ )
    {    
        if ( pStudent->bExit )
        {
            SetEvent(hand[0]);
            return 0;
        }
        ::SendMessage( pStudent->wnd->GetSafeHwnd() , WM_USER_ADD , pStudent->nNO++, 0 );
        Sleep(500);
    }
    return 0;
}

UINT threadADD1( LPVOID p )
{
    Student *pStudent = ( Student *)p;
    for ( int i = 0; i<1000000; i++ )
    {
        if ( pStudent->bExit )
        {
            SetEvent( hand[1]);
            return 0;
        }
        ::SendMessage( pStudent->wnd->GetSafeHwnd() , WM_USER_ADD1 , (pStudent->nYear)--,0);
        Sleep( 500 );
    }
    return 0;
}

退出程序：
BOOL CMyDlg::ExistThread()
{
    m_crisecoin.Lock();
    stdent.bExit = TRUE;
    m_crisecoin.Unlock();
    DWORD dwWait =0;
    dwWait = ::WaitForMultipleObjects( 2, hand , TRUE,INFINITE);
    return TRUE;
}
//挂起线程;
void CMyDlg::OnBnClickedButtonSuperthread()
{
    SuspendThread( pThread[0]->m_hThread );
    SuspendThread( pThread[1]->m_hThread );
}
//唤起线程
void CMyDlg::OnBnClickedButtonResunme()
{
    ResumeThread( pThread[0]->m_hThread );
    ResumeThread( pThread[1]->m_hThread );

}
