貌似挂起线程必须在主界面的UI线程去操作

UINT UiThreadProcessProtocol(LPVOID lParam)
{
    CCalcPPIView* view = (CCalcPPIView*)lParam;
    DmcControler* Dmc = &(view->Dmc);

    while (1)
    {
        //AfxTrace("%u \n",GetTickCount());
        Sleep(500);
    }
    return 0;
}

CWinThread* m_ThreadProcessProtocol;
m_ThreadProcessProtocol = AfxBeginThread(UiThreadProcessProtocol,this);

void CCalcPPIView::OnBtnRegulate()
{
    if (m_ThreadProcessProtocol!=NULL) {
        m_ThreadProcessProtocol->SuspendThread();
        AfxTrace("SuspendThread() at %u \n",GetTickCount());
    }

    {
        CRegulate dlg(this);
        dlg.DoModal();
    }
    if (m_ThreadProcessProtocol!=NULL) {
        m_ThreadProcessProtocol->ResumeThread();
        AfxTrace("ResumeThread() at %u \n",GetTickCount());
    }
}

void CCalcPPIView::CloseDevice(BOOL bUpdateUI )
{
    CCalcPPIView* view = this;
    AfxTrace("CCalcPPIView::CloseDevice() Entry \n");

    Dmc.SetOpened(0);

    if (view->m_ThreadProcessProtocol!=NULL) {
        WaitForSingleObject(view->m_ThreadProcessProtocol->m_hThread,INFINITE);
        view->m_ThreadProcessPro NULL;
    }
}
