IDebugBoundBreakpoint2::Enable

  • 發行項

啟用或停用斷點。

語法

int Enable( 
    int fEnable
);

參數

fEnable
[in]設定為非零 （TRUE） 以啟用或設為零 （FALSE） 以停用斷點。

傳回值

如果成功，則會傳回 S_OK；否則，會傳回錯誤碼。 E_BP_DELETED如果繫結斷點物件的狀態設定為 BPS_DELETED （BP_STATE 列舉的一部分），則傳回 。

範例

下列範例示範如何為公開IDebugBoundBreakpoint2 介面的簡單CBoundBreakpoint物件實作這個方法。

HRESULT CBoundBreakpoint::Enable(BOOL fEnable)
{
    HRESULT hr;

    // Verify that the bound breakpoint has not been deleted. If deleted,
    // then return hr = E_BP_DELETED.
    if (m_state != BPS_DELETED)
    {
        // Check the state of the bound breakpoint. If the breakpoint is
        // supposed to be, but has not already been, enabled, then have the
        // interpreter set the breakpoint.
        if (fEnable && m_state != BPS_ENABLED)
        {
            hr = m_pInterp->SetBreakpoint(m_sbstrDoc, this);
            if (hr == S_OK)
            {
                // Change the state of the breakpoint to BPS_ENABLED.
                m_state = BPS_ENABLED;
            }
        }
        // Check the state of the bound breakpoint. If the breakpoint is
        // supposed to be, but has not already been, disabled, then have the
        // interpreter remove the breakpoint.
        else if (!fEnable && m_state != BPS_DISABLED)
        {
            hr = m_pInterp->RemoveBreakpoint(m_sbstrDoc, this);
            if (hr == S_OK)
            {
                // Change the state of the breakpoint to BPS_DISABLED.
                m_state = BPS_DISABLED;
            }
        }
        else
        {
            hr = S_FALSE;
        }
    }
    else
    {
        hr = E_BP_DELETED;
    }

    return hr;
}
